• BBL Speaker Series: Cooperative Inquiry: When Children and Adults Design Together

  Date: Sep 19th, 2024 12:30 PM
  Talk Title:  Cooperative Inquiry: When Children and Adults Design Together
  Speaker:  beth bonsignore, Associate Research Professor; Director, BA in Tech & Info Design; Director, KidsTeam
  Location: HBK 2105 and Zoom
  Abstract:  The goal of Participatory Design is to include as many people (users) as possible in all stages of the technology design process. Initially, it was unclear whether children could be actively involved in participatory design in any role beyond "end user" or "tester." In 1998, KidsTeam was launched at UMD’s Human-Computer Interaction Lab to explore practical and ethical questions about co-design between children and adults. This research resulted in Cooperative Inquiry, a design-based research approach that is now in use internationally across academia and industry. Its participatory design practices and techniques have been incorporated into HCI curricula and integrated into design-based research in the Learning Sciences, with impacts on industry practice. KidsTeam has also expanded its reach, demonstrating its replicability, utility, and generalizability as similar intergenerational co-design capabilities have been created in university/K-12, not-for-profit, and industry settings. More recently, new horizons for intergenerational co-design have opened up. For example, the Cooperative Inquiry design framework has become foundational in emerging critical design and computational empowerment programs. This raises interesting research questions about the role of youth in these new efforts. In this talk, Beth will provide a brief overview of KidsTeam at UMD: how it started, how it's going, and how it might best meet these new challenges.
  Bio:  Elizabeth (“beth”) Bonsignore is an associate research professor at UMD’s College of Information and Human-Computer Interaction Lab (HCIL). Her research explores the design of interactive play and social experiences that promote new media literacies and arts-integrated science learning. She co-designs and advocates with youth, families, and local communities with the goal of empowering youth historically underrepresented in STEM to advance in these fields. Her recent collaborations with amazing graduate students have explored the challenges (and conundrum) of making participatory design as inclusive as possible through assets-based design and funds of identity.  

• BBL Speaker Series: Student Lightning Talks

  Date: Sep 26th, 2024 12:30 PM
  Talk Title:  Student Lightning Talks
  Location: HBK 2105 and Zoom
  Description: 
  This BBL will be dedicated to four student lightning talks. We are excited to hear what they are working on!
  How do lightning talks work? 
  Typically, people give a 4-5 minute "presentation" -- this can be very informal or involve slides. The presentation gives some background on your project and then introduces a specific question or "ask" that you want feedback on. Then we have ~15 minutes of conversation with attendees about your question/topic. This is a great opportunity for students to get feedback on research ideas or projects in various stages.  

• BBL Speaker Series: From Haptic Illusions to Beyond Real Interactions in Virtual Reality

  Date: Oct 3rd, 2024 12:30 PM
  Talk Title: From Haptic Illusions to Beyond Real Interactions in Virtual Reality Speaker:  Parastoo Abtahi, Assistant Professor of Computer Science, Princeton University
  Location: HBK 2105 and Zoom
  Watch Here
  Abstract:  Advances in audiovisual rendering have led to the commercialization of virtual reality (VR) hardware; however, haptic technology has not kept up with these advances. While haptic devices aim to bridge this gap by simulating the sensation of touch, many hardware limitations make realistic touch interactions in VR challenging. In my research, I explore how by understanding human perception, we can design VR interactions that not only overcome the current limitations of VR hardware but also extend our abilities beyond what is possible in the real world. In this talk, I will present my work on redirection illusions that leverage the limits of human perception to improve the perceived performance of encountered-type haptic devices, such as improving the position accuracy of drones, the speed of tabletop robots, and the resolution of shape displays when used for haptics in VR. I will then present a framework I have developed through the lens of sensorimotor control theory to argue for the exploration and evaluation of VR interactions that go beyond mimicking reality.

  Speaker:  Chelsea Butkowski (left), American University & Frances Corry (right), University of Pittsburgh
  Location: HBK 2105 and Zoom
  Watch Here
  Abstract:  Though the social media ecosystem has never been   stable—with platforms constantly emerging, evolving, aging, and closing—the last few years have appeared particularly volatile. Major companies like Meta and X have undergone historic transformations, and a slew of new platforms have also emerged, including TikTok, BeReal, Threads, Bluesky, Mastodon, and others. It appears as if social media companies, the platforms they run, and the users they support, have arrived at an existential juncture. What is social media for in today’s society––and what does its future look like? Decades on, is “new media” still “new” after all? In this talk, Drs. Chelsea Butkowski and Frances Corry draw on their recent research analyzing press coverage of emerging platforms to argue that contemporary social media discourse has become fueled by cultural memory, a phenomenon that they call “nostalgic anticipation.” In other words, speculation about social media's volatile future is persistently filtered through a yearning for its past. Butkowski and Corry will discuss how this unique juncture for social media can contribute to reframing understandings of platforms in our scholarship and our everyday lives.

• BBL Speaker Series: Scaling Expertise via Language Models with Applications to Education

  Date: Oct 17th, 2024 12:30 PM
  Talk Title:Scaling Expertise via Language Models with Applications to Education
  Speaker:  Rose Wang, Computer Science PhD candidate, Stanford University
  Location: HBK 2105 and Zoom
  Watch Here
  Abstract: Access to expert knowledge is essential for fostering high-quality practices across domains like education. However, many novices—such as new teachers—lack expert guidance, limiting their growth and undermining student outcomes. While language models (LMs) hold potential for scaling expertise, current methods focus on surface patterns rather than capturing latent expert reasoning. In this talk, I'll discuss how my research addresses this by (1) identifying problematic practices for intervention from noisy, large-scale interaction data, (2) developing benchmarks that measure expert quality of practices, and (3) extracting latent expert reasoning to adapt LMs for real-time educational interventions. I'll highlight how my methods have been deployed to improve K-12 education at scale, positively impacting millions of live interactions between students and educators.

• BBL Speaker Series: Designs to Support Better Visual Data Communication

  Date: Oct 24th, 2024 12:30 PM
  Talk Title:  Designs to Support Better Visual Data Communication
  Speaker:  Cindy Xiong, Assistant Professor, School of Interactive Computing, Georgia Institute of Technology
  Location: HBK 2105 and Zoom
  Watch Here
  Abstract:  Well-chosen data visualizations can lead to powerful and intuitive processing by a viewer, both for visual analytics and data storytelling. When badly chosen, visualizations leave important patterns opaque or misunderstood. So how can we design an effective visualization? I will share several empirical studies demonstrating that visualization design can influence viewer perception and interpretation of data, referencing methods and insights from cognitive psychology. I leverage these study results to design natural language interfaces that recommend the most effective visualization to answer user queries and help them extract the ‘right’ message from data. I then identify two challenges in developing such an interface. First, human perception and interpretation of visualizations is riddled with biases, so we need to understand how people extract information from data. Second, natural language queries describing takeaways from visualizations can be ambiguous and thus difficult to interpret and model, so we need to investigate how people use natural language to describe a specific message. I will discuss ongoing and future efforts to address these challenges, providing concrete guidelines for visualization tools that help people more effectively explore and communicate data.

• BBL: Speaker Series: A New Model for News Engagement Depends on Human-Computer Interaction

  Date: Oct 31st, 2024 12:30 PM
  Talk Title: A New Model for News Engagement Depends on Human-Computer Interaction
  Speaker: Dr. Ronald Yaros, Associate Professor, UMD’s Digital Engagement Lab (.org) Philip Merrill College of Journalism
  Location: HBK 2105 and Zoom
  Watch Here
  Abstract:  Despite the enduring importance of quality writing, reporting, and sourcing in local journalism, digital communicators have yet to fully leverage cutting-edge research from other disciplines to meet the evolving needs of today’s news consumers. Since 2005, Yaros has combined journalism with concepts from cognitive psychology, educational psychology, and human-computer interaction to develop a new model for digital engagement. The unique model combines ten user and content variables and is incorporated into a “smart story suite” so users can select their news narrative. The interface builds what Yaros calls "attention momentum" without depending on clickbait, text-heavy pages, and video. As news consumption and advertising revenues continue to decline, the model seeks to increase the probability that more users will spend more time with more news. Yaros looks forward to presenting this applied research and welcomes collaboration with his team in the digital engagement lab.
  Bio:  Dr. Yaros is an Associate Professor in the Philip Merrill College of Journalism and an Affiliate Associate Professor in the College of Information Science. He earned his Ph.D. at the University of Wisconsin-Madison.

  Abstract:  My research focuses on the enhancements in human computer interaction in Mixed Reality. As the integration of digital and physical worlds through Mixed Reality expands the interaction space beyond traditional screens, it has a significant impact on how users perceive and interact with the world. Through user studies, I observe and model the behavioral and perceptual patterns of users as they interact with Mixed Reality. Based on the findings, I design and develop interaction techniques that are tailored to these behavioral changes in order to facilitate user input and information display. Additionally, I explore augmentation methods that allow users to surpass their capabilities in the real world, such as embodying healthier virtual avatars or non-humanoid avatars to gain unique experiences not possible in reality.

• BBL Speaker Series: Visualizing the Unseen: Perceptographer – A Pioneering AI Paradigm for Brain-Computer Interaction

  Date: Nov 14th, 2024 12:30 PM
  Talk Title: Visualizing the Unseen: Perceptographer – A Pioneering AI Paradigm for Brain-Computer Interaction
  Speaker:  Elia Shahbazi
  Location: HBK 2105 and Zoom
  Abstract:  Understanding the complexities of human perception is a fundamental challenge in neuroscience. We have recently developed an innovative approach called Perceptography to visualize intricate perceptual distortions resulting from localized brain stimulation in the inferotemporal (IT) cortex. Perceptography leverages machine learning to create and refine specific image distortions that are challenging for animals to distinguish from the effects of cortical stimulation. In this talk, I will present Perceptographer, a groundbreaking, customizable framework for visualizing brain-stimulation-induced perceptual events across various regions of the visual cortex. By overcoming the limitations of existing image generation models in handling complex distortions, Perceptographer opens new pathways for exploring and understanding the intricate phenomena of brain induced perception.

• BBL Speaker Series: Intent-AI Interaction: Elevating Human-Computer Interaction to the Intent and Conceptual Level

  Date: Nov 21st, 2024 12:30 PM
  Talk Title: Intent-AI Interaction: Elevating Human-Computer Interaction to the Intent and Conceptual Level
  Speaker:  Jason Ding
  Location: HBK 2105 and Zoom
  Watch Here
  Abstract:  Technological advancements are continually reshaping human-computer interaction (HCI). Although direct manipulation methods, such as clicking and dragging icons in graphical user interfaces (GUIs), remain widespread, generative AI now has the ability to understand user interfaces and autonomously perform tasks. This reduces the reliance on direct user manipulation and prompts a reimagining of HCI paradigm. In this talk, we introduce "intent-AI interaction" as a forward-looking paradigm where interactions are driven by the user's intent and conceptual reasoning rather than command-level actions. We will demonstrate this paradigm shift through three studies: human-AI co-creation of news headlines, ideation enabled by cross-domain analogies, and data exploration.

  Speaker:  Yasmine Kotturi, Assistant Professor of Human-Centered Computing, Information Systems, University of Maryland, Baltimore County
  Location: HBK 2105 and Zoom
  Watch Here
  Abstract:  The “future of work” promises innovation and opportunity, yet for many, it manifests as uncertainty and instability—exposing a stark divide between optimistic predictions and lived realities. In this talk, I explore the critical role of peer networks in addressing worker challenges such as isolation and skill development in digitally-mediated work. Drawing on community-based, participatory design methods, I present three peer support systems—Hirepeer, Peerdea, and Tech Help Desk—that tackle these issues by fostering trust and accountability within worker communities. These systems demonstrate how localized, community-based approaches can overcome the limitations of current approaches to building sociotechnical systems which prioritize scale over relationship building. Finally, my work highlights the importance of constructive community-academic partnerships in computing which kickstart and sustain community initiatives.

• BBL Speaker Series: “Making Data Strange in Nonprofit Organizations”

  Date: Feb 6th, 2025 12:30 PM
  Talk Title: Making Data Strange in Nonprofit Organizations
  Speaker: Dr. Amy Voida, Associate professor and founding faculty in the Department of Information Science, University of Colorado Boulder
  Location: HBK 2105 and Zoom
  Abstract: "This is a talk with an alter ego. As a research talk, I explore the myriad ways in which the use of data in nonprofit organizations disrupts our expectations of what it means to design organizational information systems — defamiliarizing data or… making data strange. From needing to address the coerciveness of the nonprofit database’s primary key to requiring new approaches for identifying the manipulative uses of data by ideologically polarized nonprofits, research about this sector serves as a critical case study of information systems at a state of enormous precarity and politicization. The research talk’s alter ego is a teaching talk in which I introduce defamiliarization, a construct that transcends subdisciplines and extends from one end of the design process to the other. Despite this impressive resume, defamiliarization is rarely taught in our curriculum, so I also take this opportunity to share seven strategies for using defamiliarization in your own work. I conclude by offering a glimpse of a new course I have designed to put defamiliarization center stage."

• BBL Speaker Series: “Steps Towards an Infrastructure for Scholarly Synthesis”

  Date: Feb 13th, 2025 12:30 PM
  Talk Title:  Steps Towards an Infrastructure for Scholarly Synthesis
  Speaker:  Dr. Joel Chan, Assistant Professor; Assistant Director, PhD Information Studies; Associate Director, HCIL
  Location: HBK 2105 and Zoom
  Abstract:  Sharing, reusing, and synthesizing knowledge is central to research progress. But these core functions are not well-supported by our formal scholarly publishing infrastructure: documents aren't really the right unit of analysis, so researchers resort to laborious "hacks" and workarounds to "mine" publications for what they need. Information scientists have proposed an alternative infrastructure based on the more appropriately granular model of a discourse graph of claims, and evidence, along with key rhetorical relationships between them. However, despite significant technical progress on standards and platforms, the predominant infrastructure remains stubbornly document-based. What can HCI do about this? Drawing from infrastructure studies, I diagnose a critical infrastructural bottleneck that HCI can help with: the lack of local systems that integrate discourse-centric models to augment synthesis work, from which an infrastructure for synthesis can be grown. In this talk, I'll describe what we can and should build in order to grow a discourse-centric synthesis infrastructure. Drawing on 3 years of research through design and field deployment in a distributed community of hypertext notebook users, I'll sketch out a design vision of a thriving ecosystem of researchers authoring local, shareable discourse graphs to improve synthesis work, enhance primary research and research training, and augment collaborative research. I'll discuss how this design vision -- and our empirical work -- contributes steps towards a new infrastructure for synthesis, and increases HCI's capacity to advance collective intelligence and solve infrastructure-level problems.
  Bio: Dr. Chan’s research and teaching explore systems that support creative knowledge work. He conceives of “systems” very broadly, from individual cognitive skills, interfaces, tools and practices, to collaborative and organizational dynamics and tools, collective intelligence and crowdsourcing, social computing, all the way to sociotechnical infrastructures within which knowledge work is done. Dr. Chan is also broadly interested in creative work across many domains, although he spends most of his time considering the disciplines of design and scientific discovery. His long-term vision is to help create a future where any person or community can design the future(s) they want to live in. Before coming to the College of Information Studies, Dr. Chan was a Postdoctoral Research Fellow and Project Scientist in the Human-Computer Interaction Institute (HCII) at Carnegie Mellon University. Dr. Chan received his Ph.D. in Cognitive Psychology at the University of Pittsburgh.

• BBL Speaker Series: Engineering Bodies and Subjectivity

  Date: Feb 27th, 2025 12:30 PM
  Talk Title:  Engineering Bodies and Subjectivity
  Speaker:  Jun Nishida, Assistant Professor, Department of Computer Science and Immersive Media Design program, University of Maryland, College Park
  Location: HBK 2105 and Zoom
  Abstract: While today’s tools allow us to communicate effectively with others via video and text, they leave out other critical communication channels, such as physical skills and embodied knowledge. These bodily cues are important not only for face-to-face communication but even when communicating motor skills, subjective feelings, and emotions. Unfortunately, the current paradigm of communication is rooted only in symbolic and graphical communication, leaving no space to add these additional haptic and/or somatosensory modalities. This is precisely the research question I tackle: how can we also communicate our physical experience across users? In this talk, I introduce how I have engineered wearable devices that allow for sharing physical experiences across users, such as between a physician and a patient, including people with neuromuscular impairments and even children. These custom-built user interfaces include exoskeletons, virtual reality systems, and interactive devices based on electrical muscle stimulation. I then investigated how we can extend this concept to support interactive activities, such as product design, through the communication of one's bodily cues. Lastly, I discuss how we can optimize our subjectivity using the psychophysics approach, such as a sense of agency, when our bodies are modified, actuated, or shared with a computer or a human partner. I conclude my talk by discussing how we can further explore the possibilities enabled by a user interface that communicates more than audio-visual cues and the roadmap for using this approach in new territories, such as understanding how our bodies, perceptions, and somatic interactions contribute to the formation of human embodiment, subjectivity, and behavior.

  Speaker:  Dr. Elissa M. Redmiles, Clare Luce Boothe Assistant Professor, Computer Science Department, Georgetown University; Faculty Associate, Berkman Klein Center for Internet & Society, Harvard University.
  Location: HBK 2105 and Zoom
  Abstract:  The creators of sexual content face a constellation of unique online risks. In this talk I will review findings from over half a decade of research I’ve conducted in Europe and the US on the use cases, threat models, and protections needed for intimate content and interactions. We will start by discussing what motivates for the consensual sharing of intimate content in recreation ("sexting") and labor (particularly on OnlyFans, a platform focused on commercial sharing of intimate content). We will then turn to the threat of image-based sexual abuse, a form of sexual violence that encompasses the non-consensual creation and/or sharing of intimate content. We will discuss two forms of image-based sexual abuse: the non-consensual distribution of intimate content that was originally shared consensually and the rising use of AI to create intimate content without people’s consent. The talk will conclude with a discussion of how these issues inform broader conversations around internet governance, digital discrimination, and safety-by-design for marginalized and vulnerable groups.

  Date: Mar 13th, 2025 12:30 PM
  Talk Title: Trans Technologies
  Speaker:  Oliver Haimson, Assistant Professor, University of Michigan School of Information
  Location: HBK 2105 and Zoom
  Abstract:  In this talk, drawing from my new book Trans Technologies (MIT Press, 2025), I discuss how technology creates new possibilities for transgender people, and how trans experiences, in turn, create new possibilities for technology. Mainstream technologies often exclude or marginalize transgender users, but when trans creators take technology design into their own hands, transformative possibilities emerge. Through in-depth interviews with over 100 creators of trans technology—including apps, games, health resources, extended reality systems, and supplies designed to address challenges trans people face—I uncover what trans technology means and explore its possibilities, limitations, and future prospects. I examine the design processes that brought these technologies to life, the role of community in their creation, and how they empower trans individuals to create their own tools to navigate a world that often fails to meet trans needs. This work highlights the successes and limitations of current trans technologies, identifies gaps still to be addressed, and investigates how privilege, race, and access to resources shape which trans technologies are created, who benefits, and who may be left out. Finally, I chart new directions for design and innovation to drive meaningful social change, inviting us to rethink the relationship between technology and marginalized communities.

  Talk Title:Reading, Augmented
  Speaker:  Andrew Head, Assistant Professor, Computer Science, University of Pennsylvania
  Location: HBK 2105 and Zoom
  Abstract:  Have you ever read a text and failed to get much out of it? Why did that happen? There is a good chance it is because you came to a text with different context than the author expected. In this talk, I offer a vision of texts where they are always augmented to provide the necessary context. These texts explain their complex jargon. They simplify their own dense passages. They provide indexes into their best passages. And they enliven the stuffiest notations. Then, I show this vision is close to reality. It is based on a series of novel interfaces my lab and collaborators have developed. Lab studies of these interfaces have shown they improve information acquisition and change the way readers navigate texts. Their design has even influenced production reading applications. Come to this talk to examine a most common intellectual activity—reading—from a new viewpoint.

  Talk Title: Threat Modeling Reproductive Health Privacy
  Speaker:  Dr. Nora McDonald, Assistant Professor,  Department of Information Science and Technology, George Mason University
  Location: HBK 2105 and Zoom
  Abstract: In a post-Roe landscape, reproductive privacy has become increasingly complex and high-stakes. This talk draws on mixed-methods research with healthcare providers and people who can become pregnant to examine how both groups understand and respond to evolving privacy risks. My work with colleagues found that providers’ privacy threat models often overlook new legal, digital, and contextual risks. While many are thinking critically about patient safety, their models need updating. Meanwhile, patients—deeply aware of their risks—are increasingly taking extreme privacy measures but still rely on guidance from providers. I conclude by proposing a concept that I have been evolving over the years, privacy intermediaries, as a promising framework to support people navigating these urgent, evolving threats.

  Speaker: Dr. Vinitha Gadiraju, Assistant Professor, Department of Computer Science, Wellesley College
  Location: HBK 2105 and Zoom
  Abstract:  Generative AI holds immense potential to revolutionize how we work, communicate, and access information. But are we building a future that includes everyone? In this talk, we will delve into how Large language models (LLMs) trained on real-world data can inadvertently reflect harmful societal biases, particularly toward people with disabilities and other marginalized communities. As we discuss biases, we will characterize the subtle yet harmful stereotypes people with disabilities have encountered that were reinforced by LLM-based chatbots, such as inspiration porn and able-bodied saviors. In contrast, we will also examine the creative and resourceful ways people with disabilities leverage these tools, how chatbots fit into their technological ecosystem, and their desires for the next iteration of generative AI tools. Finally, we will contemplate the role of chatbots in common and high-risk use cases in the context of previous foundational research and disability justice principles.

  Abstract: 
  Novel HCI devices are prone to planned obsolescence, which sometimes causes clever ideas and great sensor packages to be trashed before being thoroughly explored. This is a particular problem in closed-source hardware designed with strongly opinionated interfaces. The Myo armband by Thalmic Labs packed high-grade EMG sensors into a successful, compact wearable, before being discontinued in 2018. This talk covers how we repurposed a Myo armband to take advantage of its subtle muscle tracking to activate a pneumatic sculpture made from materials that are similarly regarded as junk in the making. This creative hacking approach is a promising way to thwart planned obsolescence, which is especially important when it comes to HCI and accessibility devices.

  By interfacing a Myo to a Raspberry Pi 3B+, we enabled forearm muscles to trigger air valves and animate assemblies of latex, bamboo, and PLA. These forms were then programmed to maintain peristalsis, only to dramatically deflate and flop about in response to custom gesture control. Though the interactions aim more for surprise and delight than technical polish, this comedy of errors examines the latent expressiveness of both the obsolete Myo hardware and everyday trash. It also allowed us to explore which software systems, exactly, would be required to take further advantage of the Myo system in an open-hardware environment. By finding fresh ways to work with what’s on our shelves, we hope to squeeze more value from devices otherwise destined for landfills.

• BBL Speaker Series: Rich and Intuitive Haptic Interaction for Future Computers

  Date: Feb 15th, 2024 12:30 PM
  Speaker: Jaeyeon Lee, Assistant Professor, Computer Science and Engineering, UNIST
  
  Location: HBK 2105 and Zoom
  
  Abstract: Computers became small yet powerful enough to be worn and provide information to the user in their daily life. However, interacting with those computers is still challenging, primarily due to their small and rigid form factors. This is problematic since one of the significant reasons for wearing computers is to access information from anywhere comfortably. This talk introduces studies enriching expressivity and natural interactions on small computers using the human sense of touch. It explores how wearable tactile displays can offer enhanced efficiency, comfort, and ease of use. Specifically, it compares design options for a tactile display on the backside of a smartwatch in terms of information transfer. Incorporating multiple distinct tactile sensations can increase the capacity for conveying information. Furthermore, non-contact tactile displays present an opportunity to enhance the wearability of these devices and deliver intuitive spatiotemporal patterns on the face. Finally, the findings from these studies have broader implications for future computing environments, including ultra-thin skin interfaces and technologies such as VR and AR.

  Abstract: Algorithms increasingly mediate interactions that cross the digital-physical divide, creating both online and offline safety risks. In this talk, I will share my work on understanding safety in algorithmically-mediated offline introductions (AMOIs). In AMOIs, digital platforms use algorithms to match strangers for offline meetups (e.g., online dating, gig work). Thus, harm in AMOIs transcends digital boundaries into the physical world, raising questions about how to measure harm and who bears responsibility. In my first study, I examine how women gig workers’ experiences with safety are shaped by both individual risk factors and platform design. In my second study, I systemetize harms and protective behaviors across gig workers and online daters and measure the prevalence of different harms and behaviors. Ultimately, my work shows that users who engage in seemingly disparate kinds of AMOIs actually share many safety concerns and protective behaviors.

  Abstract: Online harassment is a problem that we still have been unable to solve in the social media age of Web 2.0. Moreover, as we move deeper into Web 3.0, which includes 3D virtual worlds, moderation moves beyond content to include behavioral components such as embodied interactions. While much of the research in computing focuses on how to deal with bad content through technological advancement, this talk presents research from the past few years that focuses on the social complexities involved when communities, rather than companies, try to self moderate.

  Abstract: Today, I want to discuss how we can leverage the vast amount of data from social media to gain insights into mental health and community engagement. I will start by exploring the impact of online depression communities. Initial concerns focused on the potential for negative emotion spread, research reveals a surprising trend: members often experience positive changes in their emotional language use and language impairment over time. This suggests that these communities can hold unexpected benefits for both mental well-being.
  
  Building on this understanding, I’ll introduce a study examining how to encourage active participation in online health communities. We delve into the concept of homophily, which describes our natural tendency to connect with those who share something similar. Here we look at language patterns. Our findings across diverse online communities show that shared vocabulary significantly predicts future interaction among members. This holds valuable implications for fostering deeper engagement and meaningful peer support by harnessing the power of shared language.

  Location: HBK 2105 and Zoom
  
  Abstract: Agency and communication are essential to our personal development, we advance our individual goals by communicating them. Nonetheless, agency is not a fixed property. Many individuals who use speech-generating devices to communicate encounter social constraints and barriers that reduce their agency in conversation including how much they can say, how they can say it, and when they can say it. In this BBL talk, I will argue how using agency as a design framework can serve us to generate accessible communication experiences and center the perspectives of people with disabilities in the design process of new technology. Through empirical studies and co-design with people with disabilities I explore how different technology materials can support their agency in conversation. In doing so, I will present accessible design methods as well as new design guidelines for augmented communication using automated transcription, physical artefacts, and AI-based language generative tools.
  
  Bio: Stephanie Valencia, PhD,  is an assistant professor at the College of  Information Studies at the University of Maryland. Dr. Valencia is a Human-Computer Interaction researcher who builds accessible technologies that are grounded in behavioral theory, co-designed with people with disabilities, and deployed to users for impact. Her research focuses on designing for accessibility and conversational agency when using assistive technologies such as augmentative and alternative communication (AAC) devices that support communication for users with motor and speech disabilities. Dr. Valencia uses participatory design to explore how different design materials such as AI and non-anthropomorphic robots can be used to create agency-increasing AAC systems and builds and deploys these systems to evaluate their impact.

  Location: HBK 2105 and Zoom
  
  Watch Here!
  
  Abstract: What is this thing AI? Is it the possible mimicry of the technical, social, or cultural intelligence of the human or the actuality of superintelligence? But wait, which Human, the Hegelian Man-as-Human or the Wynterian Beyond MAN, towards the Human? We don’t know! This thing AI that was presented to us during the short-lived summers and long cold winters will solve the “common sense” problem, i.e., model human knowledge of the everyday, what Heideggerian phenomenology calls “Being-in-the-World”.
  
  In this talk, I will introduce a particular dimension of the Heideggerian critique of AI, i.e. enflaming [Gestell] and standing reserve [Bestand]. In particular, I will adopt the concept of standing reserve to articulate a particular relation of the African citizen – a user, a client, a producer, or a labourer- within a largely Eurocentric AI landscape, and attempt to demonstrate how the existing institutional conception of the African as an objectifiable subject that can be resourced for capital will inform (and reform) the African orientation of the future of AI. In short, I will argue that the African, just as Kalluri and colleagues (2023) “Surveillance AI pipeline” paper has demonstrated how Humans are conceived as entities under the umbrella term of “objects” or “region of interest” in computer vision research, is historically and continuously co-opted as standing reserve for the total mobilization of technocratic ideals – thus to be catalogued, computed and used as resource that is disposable and replaceable.

  Abstract: After increasing rapidly over seven years, the number of active contributors to English Wikipedia peaked in 2007 and has been in decline since. A body of evidence will be presented that suggests English Wikipedia’s pattern of growth and decline appears to be a general feature of “peer production”—the model of collaborative production that has produced millions of wikis, free/open source software projects, websites like OpenStreetMap, and more. It will be argued that this pattern of growth, maturity, and decline is not caused by newcomers who have stopped showing up, but rather because communities have become less open to the newcomers who do arrive. A theoretical model and a range of empirical evidence will be provided that suggests why this surprising dynamic may be a rational approach to the shifting governance challenges faced by digital knowledge commons.

• BBL Speaker Series: On the Politics of Algorithmic Accountability: Comparing the Impacts of AI on Financially Vulnerable Communities in India and the US

  Date: Apr 11th, 2024 12:30 PM
  Speaker: Divya Ramesh, PhD candidate, Computer Science and Engineering, University of Michigan, Ann Arbor
  
  Location: HBK 2105 and Zoom
  
  Abstract: Algorithmic accountability ensures that the design, development, and use of AI systems has public approval and trust. However, barring a few success stories, accountability as a governance mechanism to ensure public trust in AI remains elusive. Recent work suggests that accountability mechanisms may be effective in a handful of democratic, rich, and western contexts. Algorithmic accountability also relies on the support of a critical public, watchdog journalism and strong institutions; these conditions are not universally available or true. How does algorithmic accountability mediate in contexts when one or more preconditions are not true? How do vulnerable users of AI systems perceive their relations to algorithmic accountability in such contexts?
  
  In this talk, I will present two examples from my research that give a glimpse into how AI-based decisions govern financially vulnerable communities in India and the US; and how such communities perceive their relations to algorithmic accountability. Placing the two case studies in conversation with one another does two things: 1) nudges us to examine the political nature of algorithmic accountability, and 2) raises questions about the extent to which our current accountability proposals address the needs of vulnerable communities around the world. I will conclude by re-centering the politics of technical questions in human-centered AI, and proposing alternative governance approaches that could better address the needs of vulnerable communities and rebuild their trust in AI.

• BBL Speaker Series: Decoding Teenagers’ Implicit Struggles with Accessibility and Safety in Computing Technologies

  Date: Apr 18th, 2024 12:30 PM
  Speaker: Alex Wen, Postdoctoral researcher, Computer Science Department, Virginia Tech
  
  Location: HBK 2105 and Zoom
  
  Abstract: This talk will explore the implicit struggles teenagers face in using computing technologies, focusing on the challenges presented by e-learning tools and social virtual reality (VR) applications. It uncovers that teenagers frequently conceal their emotional distress arising from learning challenges, exacerbated by the accessibility issues of e-learning tool designs. Furthermore, within social VR settings, teenagers demonstrate overconfidence in their protective strategies and a misplaced sense of safety, issues arising from inadequate design of interaction safety measures. These findings highlight the unique needs of teenagers, distinct from those of adults, shaped by their specific social situations and evolving mental models. Through a sociological lens, I aim to deepen the understanding of these needs and identify solutions that truly meet the teenagers. My goal is to design digital environments that are both accessible and safe for all young users, catering specifically to the nuanced demands of teenagers.

• BBL Speaker Series: Envisioning Identity: The Social Production of Computer Vision

  Date: Apr 25th, 2024 12:30 PM
  Speaker: Morgan Klaus Scheuerman, Postdoctoral Associate, Information Science, University of Colorado Boulder
  
  Abstract: Computer vision technologies have been increasingly scrutinized in recent years for their propensity to cause harm. Broadly, the harms of computer vision focus on demographic biases (favoring one group over another) and categorical injustices (through erasure, stereotyping, or problematic labels). Prior work has focused on both uncovering these harms and mitigating them, through, for example, better dataset collection practices and guidelines for more contextual data labeling. There is opportunity to further understand how human identity is embedded into computer vision not only across these artifacts, but also across the network of human workers who shape computer vision systems. Further, given computer vision is designed by humans, there is ample opportunity to understand how human positionality influences the outcomes of computer vision systems. In this talk, I present work on how identity is implemented in computer vision, from how identity is represented in models and datasets to how different worker positionalities influence the development process. Specifically, I showcase how representations of gender and race in computer vision are exclusionary, and represent problematic histories present in colonialist worldviews. I also highlight how traditional tech workers enact a positional power over data workers in the global south. Through these findings, I demonstrate how identity in computer vision moves from something more open, contextual, and exploratory to a completely closed, binary and prescriptive classification.
  
  Bio: Morgan Klaus Scheuerman is a Postdoctoral Associate in Information Science at University of Colorado Boulder and a 2021 MSR Research Fellow. His research focuses on the intersection of technical infrastructure and marginalized identities. In particular, he examines how gender and race characteristics are embedded into algorithmic infrastructures and how those permeations influence the entire system. His work has received multiple best paper awards and honorable mentions at CHI and CSCW. He earned his MS degree in Human-Centered Computing from University of Maryland Baltimore County and his BA in Communication & Media Studies (Minor Gender & Sexuality Studies) from Goucher College.

• BBL Speaker Series: AGI is Coming… Is HCI Ready?

  Date: May 2nd, 2024 12:30 PM
  Speaker: Merrie Morris, Director for Human-AI Interaction Research, Google DeepMind
  
  Location: HBK 2105 and Zoom
  
  Abstract: We are at a transformational junction in computing, in the midst of an explosion in capabilities of foundational AI models that may soon match or exceed typical human abilities for a wide variety of cognitive tasks, a milestone often termed Artificial General Intelligence (AGI). Achieving AGI (or even closely approaching it) will transform computing, with ramifications permeating through all aspects of society. This is a critical moment not only for Machine Learning research, but also for the field of Human-Computer Interaction (HCI).
  
  In this talk, I will define what I mean (and what I do NOT mean) by “AGI.” I will then discuss how this new era of computing necessitates a new sociotechnical research agenda on methods and interfaces for studying and interacting with AGI. For instance, how can we extend status quo design and prototyping methods for envisioning novel experiences at the limits of our current imaginations? What novel interaction modalities might AGI (or superintelligence) enable? How do we create interfaces for computing systems that may intentionally or unintentionally deceive an end-user? How do we bridge the “gulf of evaluation” when a system may arrive at an answer through methods that fundamentally differ from human mental models, or that may be too complex for an individual user to grasp? How do we evaluate technologies that may have unanticipated systemic side-effects on society when released into the wild?
  
  I will close by reflecting on the relationship between HCI and AI research. Typically, HCI and other sociotechnical domains are not considered as core to the ML research community as areas like model building. However, I argue that research on Human-AI Interaction and the societal impacts of AI is vital and central to this moment in computing history. HCI must not become a “second class citizen” to AI, but rather be recognized as fundamental to ensuring the path to AGI and beyond is a beneficial one.

• BBL Speaker Series: Exploring immersive meetings in the Metaverse: A conceptual model and first empirical insights

  Date: May 9th, 2024 12:30 PM
  Talk Title: Exploring immersive meetings in the Metaverse: A conceptual model and first empirical insights
  
  Speaker: Marvin Grabowski, PhD Candidate at University of Hamburg, Germany
  
  Location: HBK 2105 and Zoom
  
  Abstract: New technological developments open up new possibilities for the way teams can work together virtually. In particular, immersive extended reality (XR) meetings enable groups to represent, view, and interact with each other in a shared three-dimensional (3D) space. XR meetings take place in the highly publicized “metaverse”, defined as a multi-user interaction space that merges the virtual world with the real world (e.g., Dwivedi et al., 2022). By wearing a headset that blocks off perception from their current physical environment, group members become immersed into a shared virtual environment (i.e., the metaverse). Users generate realistic embodied avatars that are qualitatively different from two-dimensional (2D) video interactions, such as Zoom (e.g., Hennig-Thurau et al., 2023). We developed a conceptual framework of 3D immersive XR group meetings that integrates technological design characteristics, subjective attendee experiences, mediating mechanisms, and meeting outcomes. I am going to present our preliminary findings on meeting outcomes and individual XR experiences (i.e., group interaction characteristics, avatar perception, simulator sickness, and task load). Following the talk, you are cordially invited to discuss about opportunities and challenges of the metaverse as a platform for enabling immersive learning scenarios and conducting workplace meetings in the future.
  
  Bio: My research as a current PhD Candidate at University of Hamburg, Germany, highlights the future of workplace meetings. Between the interface of Industrial & Organizational Psychology and Human Computer Interaction, the immersive experience through VR glasses opens up new interdisciplinary perspectives. In particular, I am interested in underlying mechanisms of fruitful interactions in immersive meetings in the metaverse. Furthermore, I am interested in success factors of hybrid meetings with the goal of gaining new insights into how the new framework of New Work can be used practically Based on national and international academic stations, I am happy to build bridges between organizational needs and scientific findings. In addition, I am a speaker on career guidance and professional orientation after high-school and published the book “Early Life Crisis”.  

• BBL Speaker Series: The Road Less Taken: Pathways to Ethical and Responsible Technologies

  Date: Sep 7th, 2023 12:30 PM
  Speaker: Dr. Susan Winter, Associate Dean for Research, College of Information Studies, the University of Maryland
  
  Location: HBK 2105 and Zoom Watch Here!
  
  Abstract: Technology is no longer just about technology – now it is about living. So, how do we have ethical technology that creates a better life and a better society? Technology must become truly “human-centered,” not just “human-aware” or “human-adjacent”. Diverse users and advocacy groups must become equal partners in initial co-design and in continual assessment and management of information systems with human, social, physical, and technical components. But we cannot get there without radically transforming how we think about, develop, and use technologies. In this chapter, we explore new models for digital humanism and discuss effective tools and techniques for designing, building, and maintaining sociotechnical systems that are built to be, and remain continuously ethical, responsible, and human-centered.
  
  Bio: Dr. Susan Winter, Associate Dean for Research, College of Information Studies, the University of Maryland. Dr. Winter studies the co-evolution of technology and work practices, and the organization of work.

  Watch Here! | Slides Here!
  
  Abstract: This talk discusses the opportunities and challenges of technology to support successful aging. The population of people aged 65 and older is growing faster than any other age group worldwide. While people are living longer, it's crucial to ask whether those additional years are being lived healthier and happier. Successful aging has become a central priority at both societal and individual health levels. Technology holds the promise to significantly contribute to successful aging in various ways. For example, keeping people physically active, enabling independent living through fall detection and smart home technology, aiding in the early detection and management of diseases, as well as helping maintain social connections to reduce isolation. Keeping in mind that aging in the digital era presents its own set of challenges, we need to ensure that technologies are inclusive and accessible to everyone regardless of age. Addressing the specific needs and older adults’ factors is crucial in the endeavor to reap the benefits of technology for successful aging.

  Speaker: Ming Yin, Assistant Professor, Department of Computer Science, Purdue University
  
  Location: HBK 2105 and Zoom
  
  Watch Here! Abstract: Artificial intelligence (AI) technologies have been increasingly integrated into human workflows. For example, the usage of AI-based decision aids in human decision-making processes has resulted in a new paradigm of human-AI decision making—that is, the AI-based decision aid provides a decision recommendation to the human decision makers, while humans make the final decision. The increasing prevalence of human-AI collaborative decision making highlights the need to understand how humans and AI collaborate with each other in these decision-making processes, and how to promote the effectiveness of these collaborations. In this talk, I'll discuss a few research projects that my group carries out on empirically understanding how humans trust the AI model via human-subject experiments, quantitatively modeling humans' adoption of AI recommendations, and designing interventions to influence the human-AI collaboration outcomes (e.g., improve human-AI joint decision-making performance).

• BBL Speaker Series: Navigating the New Normal: An Exploration of Face-to -Face Design Meetings in the Era of Remote Work

  Date: Oct 19th, 2023 12:30 PM
  Speaker: Karen Holtzblatt
  
  Location: HBK 2105 and Zoom
  
  Watch Here!
  
  Abstract: Advancements in technology, the globalization of companies, and a growing awareness of environmental issues have catalyzed a shift in work cultures, transforming traditional face-to-face meetings into online ones. The COVID-19 pandemic further accelerated this transition, establishing videoconferencing as the prevailing mode of professional interaction. But now companies are asking workers to come back to the office at least some of the time. They cite better collaboration, information sharing, and coaching for early career folks. But is that true and what does it really mean? To find out, we 11 conducted deep dive interviews primarily with HCI professionals to understand their experience of working in person vs remotely or hybrid. HCI professionals often find themselves organizing, leading, facilitating, and participating in complex interactive meetings of various kinds: data synthesis, ideation, brainstorming, design review with whiteboarding, roadmapping, and project kickoffs. Our work complements recent research on Return-to-Work that has been conducted by surveys and gives a deeper understanding of what is going on. We sought to gain insights into these types of meetings and interactions to understand participants’ experiences and what works and what doesn’t. We hope these findings will helpguide both HCI professionals and companies as they choose when to be in-person and how to best run hybrid and remote meetings. We spoke with both senior people and early career professionals. Our insights are also against the backdrop of last year’s research into the experience of remote working during the pandemic and related literature. The presentation will tell stories of our experiences and explicate what drives people to bring people together for these complex meetings and what impacts the success of these meetings in any context. We will also describe the impact of the social dimension of working together. We discuss the need for a shared understanding, ensuring engagement, managing the meeting, and the powerful role of nonverbal communication as well as the need and desire for connection both for its own sake and for the sake of the work and career.

  Watch Here!
  
  Abstract: We live in a storied life. Stories from people at present and in the past are guiding our actions in the future. Although this narrative mode of knowing complements the pragmatic mode, the pragmatic mode of knowing is the only ubiquitously supported mode in personal health informatics systems. In this talk, I will present my research on personal health informatics that uses storytelling to support health behavior in marginalized communities. These studies examined how storytelling technologies can amplify social connections and knowledge within the family and neighbors. The use of stories socially is a departure from health technologies that are often individually focused. Technologies that portray health solely as an individual’s responsibility could widen health disparities because marginalized communities face numerous health barriers due to systemic inequities. Storytelling health informatics could lessen this burden by supporting health behaviors as collective community efforts.
  
  Bio: Dr. Herman Saksono is an Assistant Professor at Northeastern University with a joint appointment at the Bouvé College of Health Sciences and the Khoury College of Computer Sciences. Previously, he was a postdoctoral research fellow at the Center for Research on Computation and Society at Harvard University. He completed his Ph.D. in Computer Science at Northeastern University and a Fulbright scholarship recipient.
  
  Herman’s interdisciplinary research contributions are in Personal Health Informatics, Human-Computer Interaction, and Digital Health Equity. His research investigates how digital tools can catalyze social interactions that encourage positive health behaviors, thus facilitating collective efforts toward health equity. He conducts the entire human-centered design process by designing, building, and evaluating innovative health technologies in collaboration with local community partners. Herman published his work in ACM CHI and CSCW where he received honorable mentions for Best Paper awards.

  Speaker: Dr. Jane Chung, Associate Professor, Virginia Commonwealth University School of Nursing
  
  Location: HBK 2105 and Zoom Watch Here!
  
  Abstract: Older adult residents of low-income housing are at a high risk of unmanaged health conditions, loneliness, and limited healthcare access. Smart speakers have the potential to improve social connections and well-being among older adult residents. We conducted an iterative, user-centered design study with primarily African American older adults who lived alone in low-income housing to develop low-fidelity prototypes of smart speaker applications for wellness and social connections. Focus groups were held to elicit feedback about challenges with maintaining wellness and attitudes towards smart speakers. Through design workshops, they identified several smart speaker functionalities perceived as necessary for improving wellness and social connectedness. Then, several low-fidelity prototypes and use scenarios were developed in the following categories: wellness check-ins, befriending the virtual agent, community involvement, and mood detection. We demonstrate how smart speakers can provide a tool for their wellness and increase access to applications that provide a virtual space for social engagement. This presentation will also highlight strategies for addressing digital health inequities among socially vulnerable older adults. The goal is to enhance technology proficiency, reduce fear, and ultimately foster the acceptance of essential technologies.
  
  Bio: Dr. Jane Chung is an Associate Professor at Virginia Commonwealth University School of Nursing. She is a nurse scientist with special emphasis on aging and technology research. Her research program has two foci: 1) advancing the methods for functional health monitoring and risk detection among older adults using innovative sensor technologies and 2) improving social connectedness and well-being in socially vulnerable older adults based on advances in data science and digital technologies including novel machine learning algorithms. She currently leads two NIH-funded studies – R01 project to identify digital biomarkers of mobility that are predictive of cognitive decline in community-dwelling older adults, and R21 project where her team is developing a smart speaker-based system for automatic loneliness assessment in older adults. Recently, she has been selected as a fellow for the Betty Irene Moore Fellowship for Nurse Leaders and Innovators, and in this fellowship program, she is working on a smart speaker-based intervention designed to assist low-income older adults in managing chronic conditions and daily activities more effectively.

• BBL Speaker Series: Connecting Realities for Fluid Computer-Mediated Communication

  Date: Dec 7th, 2023 12:30 PM
  Speaker: Seongkook Heo, Assistant Professor, CS, University of Virginia
  
  Location: HBK 2105 and Zoom Slides Here!
  
  Abstract: Computers are more deeply integrated into our daily lives than ever before, and recent advancements in ML and AI technologies enable computers to comprehend the real world. However, using such capabilities for daily tasks still induces friction because of inefficient interactions with them.
  
  In this talk, I will share my group's research on how we can better connect the physical and virtual worlds through the design and development of interactive systems. First, I will discuss how we can bring objects and interactions of the physical world into the virtual world to make virtual communication rich and frictionless. In many computer-mediated meetings, we not only share our faces and voices but also physical objects. We developed a remote meeting system that supports the instant conversion of physical objects into virtual objects to allow efficient sharing and manipulation of objects during the conversation.
  
  Second, I will share how we can physicalize computation results into physical actions. Many projects and applications have demonstrated the use of AI in assisting users with visual impairments. However, computers usually only provide guidance feedback to the user and leave the interpretation of the feedback and the execution to the user, which can be cognitively heavy tasks. We suggested automated hand-based spatial guidance to bridge the gap between guidance and execution, allowing visually impaired users to move their hands between two points automatically. Finally, I will discuss the implications and remaining challenges in bridging the two realities.

• Developing an Approach to Support Instructors to Provide Emotional and Instructional Scaffolding for English Language Learners Through Biosensor-Based Feedback

  Date: Feb 16th, 2023 12:30 PM
  Abstract: In this talk, I'll present the potential of using biosensor-based feedback to support instructors in providing emotional and instructional scaffolding for English language learners (ELLs). This research includes classifying the intensity and characteristics of public speaking anxiety (PSA) and foreign language anxiety (FLA) among ELLs, with a view to providing tailored feedback to instructors. A focus group interview was conducted to identify instructors’ needs for solutions providing emotional and instructional support for ELLs. This was followed by an ideation and design session, where prototypes incorporating biosensing technology were designed to support teaching. I conclude this talk by discussing the feasibility of using electrodermal activity (EDA) to measure ELLs' emotional states, provide an algorithm for classifying speaking anxiety, and offer design guidance for an educational system using EDA data in an ESL/EFL environment as well as the instructors’ perspectives about using biosensor-based feedback in teaching. Bio: Heera Lee is a Lecturer in the Information Studies department at the University of Maryland, College Park. Her interest research area in Human-Computer Interaction (HCI) is educational technologies and affective computing for English language learners (ELLs) from diverse cultures. She has been focusing on investigating contributing factors to the public speaking anxiety (PSA) and foreign language speaking anxiety (FLA) among ELLs by analyzing their self-report questionnaire, individual interviews, non-verbal behaviors, and physiological data including electrodermal activity (EDA). These interests stem from her teaching experience as an instructor in English Language Institute (ELI), Teaching Assistant in undergraduate programs at University of Maryland, Baltimore County (UMBC), and Adjunct faculty at Towson University.

• Brown Bag Talk: Human Spaceflight Risk from Decreasing Ground Support on Long-Duration Missions Beyond Low-Earth Orbit

  Date: Mar 2nd, 2023 12:30 PM
  Abstract: Human spaceflight over the past 60 years has been remarkably safe. This has been largely due to the fact that support from Earth, in the form of near-real-time communication, resupply, and evacuation options, has been a successful countermeasure to the significant hazards associated with in-space operations. Longer duration missions to the Lunar surface, and then to Mars, will quickly break this approach, requiring a paradigm shift in terms of on-board, in-mission capabilities for increased Earth-independence. Bio: Dr. Alonso Vera is Chief of the Human Systems Integration Division at NASA Ames Research Center. He has worked at NASA for over 20 years and has served as Division Chief since 2010.

• Brown Bag Talk: Aligning incentives with institutional values

  Date: Mar 9th, 2023 12:30 PM
  

  Abstract: In this talk, I will discuss key issues underlying the current incentive systems for research evaluation, summarize existing data on the relation between key indicators of research quality and traditional metrics, and highlight some of the challenges with reputation-based systems. I argue that real reform in research evaluation requires a fundamental rethinking of how we conceptualize research productivity, moving away from traditional incentive structures that heavily weigh quantity and toward a model in which the incentives align with our institutional and scientific values. I suggest that these reforms must be designed in a way to incentivize researchers to engage in pro-social behaviors.

• Brown Bag Talk: Dr. Katie Davis discusses her new book, “Technology’s Child”

  Date: Mar 16th, 2023 12:30 PM
  Abstract: What happens to the little ones, the tweens, and the teenagers, when technology, ubiquitous in the world they inhabit, becomes a critical part of their lives? Technology’s Child brings clarity to what we know about technology’s role in child development and provides guidance on how to help children of all ages make the most of their digital experiences.
  
  From toddlers who are exploring their immediate environment to twenty-somethings who are exploring their place in society, technology inevitably and profoundly affects their development. Drawing on her expertise in developmental science and design research, Dr. Katie Davis describes what happens when child development and technology design interact, and how this interaction is complicated by children’s individual characteristics as well as social and cultural contexts.  Critically, she explains how a self-directed experience of technology—one initiated, sustained, and ended voluntarily—supports healthy child development, especially when it takes place within the context of community support, and how an experience that lacks these qualities can have the opposite effect.
  
  Bio: Katie Davis is Associate Professor at the University of Washington (UW) Information School, Adjunct Associate Professor in the UW College of Education, and a founding member and Co-Director of the UW Digital Youth Lab. Katie investigates the impact of digital technologies on young people’s learning, development, and well-being, and co-designs positive technology experiences for youth and their families. Her work bridges the fields of human development, human-computer interaction, and the learning sciences. In addition to her academic papers, Katie is the author of three books exploring technology’s role in young people’s lives: Technology’s Child: Digital Media’s Role in the Ages and Stages of Growing Up (MIT Press, 2023), Writers in the Secret Garden: Fanfiction, Youth, and New Forms of Mentoring (with Cecilia Aragon, MIT Press, 2019), and The App Generation: How Youth Navigate Identity, Intimacy, and Imagination in a Digital World (with Howard Gardner, Yale University Press, 2013).  Prior to joining the faculty at the University of Washington, Katie was a research scientist at Harvard Project Zero, where she worked on the research team that collaborated with Common Sense Media to develop the first iteration of their digital citizenship curriculum. She holds two master’s degrees and a doctorate in Human Development and Education from Harvard Graduate School of Education.

• Brown Bag Talk: Dr. Andrea Parker presents “Transforming the Health of Communities through Innovations in Social Computing”

  Date: Mar 30th, 2023 12:30 PM
  Dr. Andrea Parker Transforming the Health of Communities through Innovations in Social Computing
  
  March 30, 2023, 12:30pm ET
  
  Abstract: Digital health research—the investigation of how technology can be designed to support wellbeing—has exploded in recent years. Much of this innovation has stemmed from advances in the fields of human-computer interaction and artificial intelligence. A growing segment of this work is examining how information and communication technologies (ICTs) can be used to achieve health equity, that is, fair opportunities for all people to live a healthy life. Such advances are sorely needed, as there exist large disparities in morbidity and mortality across population groups. These disparities are due in large part to social determinants of health, that is, social, physical, and economic conditions that disproportionately inhibit wellbeing in populations such as low-socioeconomic status and racial and ethnic minority groups.
  
  Despite years of digital health research and commercial innovation, profound health disparities persist. In this talk, I will argue that to reduce health disparities, ICTs must address social determinants of health. Intelligent interfaces have much to offer in this regard, and yet their affordances—such as the ability to deliver personalized health interventions—can also act as pitfalls. For example, a focus on personalized health interventions can lead to the design of interfaces that help individuals engage in behavioral change. While such innovations are important, to achieve health equity there is also a need for complimentary systems that address social relationships. Social ties are a crucial point of focus for digital health research as they can provide meaningful supports for positive health, especially in populations that disproportionately experience barriers to wellbeing.
  
  I will offer a vision for digital health equity research in which interactive and intelligent systems are designed to help people build, enrich, and engage social relationships that support wellbeing. By expanding the focus from individual to social change, there is tremendous opportunity to create disruptive interventions that catalyze and sustain population health improvements.
  
  Bio: Andrea Grimes Parker is an Associate Professor in the School of Interactive Computing at Georgia Tech. She is also an Adjunct Associate Professor in the Rollins School of Public Health at Emory University and at Morehouse School of Medicine. Dr. Parker holds a Ph.D. in Human-Centered Computing from Georgia Tech and a B.S. in Computer Science from Northeastern University. She is the founder and director of the Wellness Technology Lab at Georgia Tech. Her interdisciplinary research spans the domains of human-computer interaction and public health, as she examines how social and interactive computing systems can be designed to address health inequities.

• Brown Bag Talk: Andy Stefik shares “Evidence Standards and Data Science for All”

  Date: Apr 6th, 2023 12:30 PM
  Talk Title: Evidence Standards and Data Science for All Abstract: Scientific fields often believe that they hold a strong basis of evidence for claims made by their own community. In practice, however, exactly what evidence is expected for a paper to be published or for a hypothesis to become an accepted theory is complex and historically bizarre. In this talk, we will discuss a snippet of the history of evidence and how these lessons are morphing into what some scholars are calling data science. In the process, we will discuss barriers and problems in data science that need resolution for it to become accessible to the general public, scholars, and notably people with disabilities.
  
  Bio: Andreas Stefik is a professor of computer science at the University of Nevada, Las Vegas. For more than a decade, he has been creating technologies that make it easier for people, including those with disabilities, to write computer software. He helped establish the first national educational infrastructure for blind or visually impaired students to learn computer science and invented the first evidence-based programming language, Quorum. The design of Quorum is created from data derived through methodologies similar to those used in the medical community. He has been a principal investigator on 8 NSF-funded grants, many of which related to accessible graphics and computer science education.

  Abstract: Recent rapid advances in machine learning have brought new energy to the future of human + machine partnerships. In this talk, I will use three research threads on interactive data visualization to better understand the balance between automation and augmentation. First, I will describe how new specifications of visual and non-visual data representations allow us to reason about visual perception and cognition. Second, I will explore how visualization can be used to bridge human mental models and machine-learned representations. And, finally, I will discuss how data visualization already exhibits an epistemological crisis of truth—one that generative models threaten to further widen.
  
  Bio: Arvind Satyanarayan is Associate Professor of Computer Science at MIT, and a member of the Computer Science and Artificial Intelligence Laboratory (CSAIL). He leads the MIT Visualization Group, which uses visualization as a lens to explore how software systems can enhance our creativity and cognition, while respecting our agency.

  Title: Affective Polarization and Support for Democratic Institutions: Evidence from Survey Experiments in Brazil, Chile, and Colombia
  
  Abstract: We examine the relationship between partisan social media messages and voters' support for democratic institutions. The experiments test whether partisan voters favor dissolving Congress or impeaching the president to advance in-group goals, considering a range of messages on consensual and wedge issues. We hypothesize that incumbent voters and opposition voters are more likely to reduce their support for democratic institutions controlled by out-group members, with opposition respondents more supportive of impeaching the president and government respondents more supportive of dissolving Congress. Partisan messages are expected to increase these effects, weakening those institutions controlled by the out-group party. We implement survey experiments in Chile, Brazil, and Colombia between October 2022 and March 2023. The experiments randomly expose respondents to partisan messages on issues such as inflation, abortion, crime, and protests. Inter-party differences conform to expectations, with opposition voters reporting higher preferences for impeaching the president and government supporters reporting higher preferences for dissolving Congress. However, we find no consistent social media effect. Incumbent and opposition voters support undemocratic policies that align with in-group goals, yet the effect does not increase with exposure to partisan social media messages on wedge issues.

  Date: May 4th, 2023 12:30 PM
  Yi Ting Huang, Associate Professor, Department of Hearing and Speech Sciences, University of Maryland
  
  Title: Technology and the future of clinical services: Language, communication, and disabilities
  
  Abstract: Speech-language pathologists and audiologists are at the front lines of improving functional language and communication across the lifespan. These include treating wide-ranging disabilities such as language disorders, autism, stuttering, hearing loss, traumatic brain injury, stroke, dementia, etc. The success of early diagnosis paired with rapidly changing US demographics have introduced two broad challenges. First, clinicians are faced with massively increasing caseloads, and new populations that were unseen decades ago. Second, clinicians are a 93% white workforce and 56% of clients identify as people of color, and this raises a host of challenges related to cultural and linguistic diversity. While existing technology has focused on specific client needs (e.g., hearing aids, AAC devices), developing tools that can increase the efficiency and efficacy of service delivery in a heavily labor-intensive industry will improve quality of life for individuals with disabilities at scale. To do so, I will introduce three on-going projects that leverage 1) telehealth to provide language therapy for children with Developmental Language Disorder, 2) automated methods for multilingual transcription to accurately assess language knowledge in bilingual children, 3) video-calling platforms for create augmented spaces for communication for autistic and neurotypical adults. These examples demonstrate how technology can reach clients that are geographically inaccessible, offer services that typically take substantial time and expertise, and alter environments that provide communicatively relevant information. I will close by considering the wealth of opportunities at the intersection of language, communication, and disabilities, and invite others to brainstorm technology applications to address urgent needs in health care access, disproportionality in diagnosis, and diversity and inclusion in the workplace.
  
  Bio: Yi Ting Huang is an Associate Professor in the Department of Hearing and Speech Sciences. She received her Ph.D. in Developmental Psychology at Harvard University and trained as a post-doctoral fellow in Cognitive Psychology at the University of North Carolina at Chapel Hill. Dr. Huang’s research focuses on how young language learners acquire the ability to coordinate linguistic representations during real-time comprehension. She explores this question by using eye-tracking methods to examine how the moment-to-moment changes that occur during processing influence the year-to-year changes that emerge during development. She has applied this approach to examine a variety of topics including word recognition, application of grammatical knowledge, and the generation of pragmatic inferences. Other interests include the relationship between language and concepts, language comprehension and production, and language development and literacy.  She is currently a member of the Maryland Language Science Center and the Program in Neuroscience and Cognitive Science.

• BBL Talk: Dr. Deokgun Park, “Cognitive Architecture for Operant Conditioning

  Date: May 11th, 2023 12:30 PM
  Cognitive Architecture for Operant Conditioning
  
  Abstract: In this talk, I will present my research on cognitive architecture for operant conditioning.  To lay the foundation for the discussion, I will start by reviewing the definitions and tests for AI and propose a new definition and the test for human-level artificial intelligence (HLAI).  I claim that the essence of HLAI to be the capability to learn from others' experiences via language.  Based on the definition, a test based on the language acquisition task will be proposed with the simulated environment to run the test practically.  A next milestone toward programming HLAI would be enabling operant conditioning inspired by the ‘Skinner box’ experiment.  To achieve this goal, I will explain two lessons that we can learn from the biological brain.  First, the working principle of neocortex can be modeled as Modulated Heterarchical Prediction Memory (mHPM). In mHPM, autoregressive universal modules in sparse distributed memory (SDM) representations are connected in a heterarchical network, and they are update in a local and distributed way instead of current deep learning trend of end-to-end optimization based on the single objective function. mHPM stores the multi-modal world model.  Second lesson is that we need non-homogeneous cognitive architecture for innate and learned behaviors instead of current homogeneous architecture.  I will explain the role of innate components such as hippocampus, reward system, hypothalamus, and amygdala.  Those innate components use the world model in mHPM enabling episodic memory formation and rapid adaptation.

• BBL Speaker Series: Aphasia Profiles and Implications for Technology Use

  Date: Sep 8th, 2022 12:30 PM
  Talk Title: Aphasia Profiles and Implications for Technology Use
  
  Speaker: Kristin Slawson, Clinical Associate Professor, University of Maryland Hearing and Speech Clinic, and Michael Settles
  
  Location: HBK 2105
  
  Abstract: Conservative estimates suggest that 2.5 million people in the US have aphasia, yet few people have ever heard of the condition. Aphasia is a poorly understood, "invisible disability" that specifically impacts use of language in all forms. People with aphasia are more likely than other stroke survivors to experience social isolation, loss of independence, and significantly lower levels of employment. These immediate consequences have negative ripple effects on the mental and physical health outcomes of survivors and their family members. This talk aims to increase awareness of specific aphasia profiles in hopes of exploring how technology can be adapted to help people with aphasia maintain their prior level of work, social engagement, and independence to the greatest degree possible.
  
  Bio: Kristin Slawson is a Speech-Language Pathologist and a Clinical Associate Professor in Hearing and Speech Sciences. As a brain injury specialist, she is particularly interested in the functional impact of brain injuries on cognitive-linguistic abilities and implications of these changes on maintenance of social connections and return to school and work.
  
  Bio: Michael Settles is a 2022 ASHA Media Champion Award for his work advocating for aphasia awareness.  He is featured in a special exhibit on aphasia and word finding at the Planet Word Museum in Washington, DC. He is an advocate for expanded use of technology to support communication needs of people with aphasia.

• BBL Speaker Series: Ideological Trajectories in Recommendation Systems for News Consumption

  Date: Sep 15th, 2022 12:30 PM
  Speaker: Cody Buntain, Assistant Professor, iSchool, UMD
  
  Location: HBK 2105
  
  Abstract: While originally developed to increase diversity in product recommendations and show individuals personalized content, recommendation systems have increasingly been criticized for their opacity, potential to radicalize vulnerable users, and incentivizing anti-social content. At the same time, studies have shown that modified recommendation systems can suppress anti-social content across the information ecosystem, and platforms are increasingly relying on such modifications for soft content-moderation interventions. These contradictions are difficult to reconcile as the underlying recommendation systems are often dynamic and commercially sensitive, making academic research on them difficult. This paper sheds light on these issues in the context of political news consumption by building several recommendation systems from first principles, populated with real-world engagement data from Twitter and Reddit. Using domain-level ideology measures, we simulate individuals' ideological trajectories through recommendations for news sources and examine whether standard recommendation approaches drive individuals to more partisan content and under what circumstances such radicalizing trajectories may emerge. We end with a discussion of personalization's impact in consuming political content, and implications for instrumenting deployed recommendation systems for anti-social effects.

• BBL Speaker Series: Assistive Smartwatch Application to Support Neurodiverse Adults with Emotion Regulation

  Date: Oct 6th, 2022 12:30 PM
  Speaker: Vivian Motti, Assistant Professor, Department of Information Sciences and Technology, George Mason University
  
  Location: HBK 2105
  
  Abstract: Emotion regulation is an essential skill for young adults, impacting their prospects for employment, education and interpersonal relationships. For neurodiverse individuals, self-regulating their emotions is challenging. Thus, to provide them support, caregivers often offer individualized assistance. Despite being effective, such an approach is also limited. Wearables have a promising potential to address such limitations, helping individuals on demand, recognizing their affective state, and also suggesting coping strategies in a personalized, consistent and unobtrusive way.  In this talk I present the results of a user-centered design project on assistive smartwatches for emotion regulation. We conducted interviews and applied questionnaires to formally characterize emotion regulation. We involved neurodiverse adults as well as parents, caregivers, and assistants as active participants in the project. After eliciting the application requirements, we developed an assistive smartwatch application to assist neurodiverse adults with emotion regulation. The app was implemented, tested and evaluated in field studies. I conclude this talk discussing the role of smartwatches to deliver regulation strategies, their benefits and limitations, as well as the users' perspectives about the technology.

• BBL Speaker Series: Toward an Equitable Computer Programming Practice Environment for All

  Date: Oct 13th, 2022 12:30 PM
  Speaker: Carl Haynes-Magyar, Presidential Postdoctoral Fellow, Carnegie Mellon University Location: HBK 2105
  
  Abstract: Traditional introductory computer programming practice has included writing pseudocode, code-reading and tracing, and code-writing. These problem types are often time-intensive, frustrating, cognitively complex, in opposition to learners' self-beliefs, disengaging, and demotivating—and not much has changed in the last decade.  Pseudocode is a plain language description of the steps in a program. Code-reading and tracing involve using paper and pencil or online tools such as PythonTutor to trace the execution of a program, and code-writing requires learners to write code from scratch.  In contrast to these types of programming practice problems, mixed-up code (Parsons) problems require learners to place blocks of code in the correct order and sometimes require the correct indentation and/or selection between a distracter block and a correct code block.  Parsons problems can increase the diversity of programmers who complete introductory computer programming courses by improving the efficiency with which they acquire knowledge and the quality of knowledge acquisition itself.  This talk will feature experiments designed to investigate the problem-solving efficiency, cognitive load, pattern application and acquisition, and cognitive accessibility of adaptive Parsons problems. The results have implications for how to generate and sequence them.
  
  Bio: Carl C. Haynes-Magyar is a Presidential Postdoctoral Fellow at Carnegie Mellon University's School of Computer Science in the Human–Computer Interaction Institute. Carl's master's work included evaluating curriculums based on their ability to develop a learner's proficiencies for assessment and assessing the relationship between perceived and actual learning outcomes during web search interaction. His doctoral work involved studying the design of learning analytics dashboards (LADs) to support learners' development of self-regulated learning (SRL) skills and investigating how people learn to program using interactive eBooks with adaptive mixed-up code (Parsons) problems. His postdoctoral work is a continued investigation into computing education that involves creating an online programming practice environment called Codespec. The goal is to scaffold the development of programming skills such as code reading and tracing, code writing, pattern comprehension, and pattern application across a gentle slope of different problem types. These types range from block-based programming problems to writing code from scratch. Codespec will support learners, instructors, and researchers by providing help-seeking features, generating multimodal learning analytics, and cultivating IDEAS: inclusion, diversity, equity, accessibility, sexual orientation and gender awareness. Carl has published several peer-reviewed articles at top venues such as the Conference on Human Factors in Computing Systems (CHI). He has taught as an instructor for courses on organizational behavior, cognitive and social psychology, human-computer interaction, learning analytics, educational data science, and data science ethics.

• BBL Speaker Series: Unobtrusive Machine-Readable Tags for Identifying, Tracking, and Interacting with Real-World Objects

  Date: Oct 22nd, 2022 12:30 PM
  Speaker: Doğa Doğan, Ph.D. candidate, MIT
  
  Location: HBK 2105
  
  Abstract: Ubiquitous computing requires that mobile and wearable devices are aware of our surroundings so as to augment the real world with contextual information that enriches our interactions with them. For this to work, the objects around us need to carry machine-readable tags, such as barcodes and RFID labels, that describe what they are and communicate this information to devices. While barcodes are inexpensive to produce, they are typically obtrusive, less durable, and less secure than other tags. Regardless of their type, most conventional tags are added to objects post hoc as they are not part of the original design.
  
  I propose to replace this post-hoc augmentation process with tagging approaches that extract objects’ integrated hidden features and use them as machine-detectable tags to make the real world more informative. In this talk, I will introduce three projects: (1) InfraredTags are invisible fiducial markers embedded into 3D printed objects using infrared-transmitting filaments, and detected using cheap infrared cameras. (2) G-ID marks different 3D printed copies of the same object by using unique printing (“slicing”) settings, which result in unobtrusive, machine-detectable surface artifacts. (3) SensiCut is a smart laser cutting platform that leverages speckle imaging and deep learning to distinguish visually similar workshop materials. It adjusts designs based on the chosen material and warns users against hazardous ones. I will show how these methods assist users in creative tasks and enable new interactive applications for augmented reality (AR), object traceability, and user identification.

  Speaker: Elena Agapie, Assistant Professor, Informatics, UC-Irvine
  
  Location: HBK 2105
  
  Abstract: Pursuing healthy behaviors is a complex, long-term process that is difficult to maintain. Many technologies promise to support people in pursuing health goals, yet many such technologies fail to account for people’s everyday needs or incorporate evidence-based strategies. In this talk, I discuss the challenges that researchers encounter in designing technologies that use health evidence-driven techniques and accounting for people’s everyday life. I use human-centered design methods and create novel systems that address key challenges that people encounter in working on health goals: starting new behaviors while accounting for the complexities of everyday life and engaging with health goals long term. I discuss how technology can better support clinicians and peers in providing evidence-driven tailored support to clients, for supporting physical activity, and mental health therapy.

  Speaker: Huaishu Peng, Assistant Professor, CS, UMD
  
  Location: HBK 2105
  
  Abstract: In this talk, I will give a brief overview of the HCI research we are conducting (or planning) in the Small Artifacts Lab. I will showcase several recent works concerning various HCI topics, e.g., design, fabrication, wearable computing, and accessibility, but all from a technical perspective. As examples, I will discuss how we designed a small wearable robot that can relocate itself on a user's full body instead of staying only in one area of interest (e.g., a smartwatch on the wrist) and how the design opens new opportunities in both research and art; I will also talk about how we created a tangible artifact that supports blind developers to create the graphical layout of webpages on their own. Towards the end of the talk, I will time and discuss with the audience how technical innovation can drive HCI research.
  
  Bio: Huaishu Peng is an Assistant Professor in the Computer Science department at the University of Maryland, College Park. He aims to advance interactive technologies by designing, prototyping, and evaluating novel artifacts that are personal, hands-on, and often small when it comes to the form factors. He is interested in the methods of building these personal artifacts (through design and interactive fabrication), the scenarios of using them (in mixed reality), and the users who can benefit from them (with assistive and enabling technology). His work has been published in CHI, UIST, and SIGGRAPH and won Best Paper Nominee.

  Location: HBK 2105
  
  Abstract: Advances in computing technology continue to offer us new insights about our health and well-being. As mutually reinforcing trends make the use of  wearable and mobile devices routine, we now collect personal, health-related data at an unprecedented scale.  Meanwhile, the use of deep-learning-based health screening technologies changes relationships between caregivers and care recipients, with multitudinous implications for equity, privacy, safety, and trust . How can researchers take inclusive and responsible approaches to envisioning solutions, training data, and deploying AI/ML-driven solutions? Who should be involved in decisions about how to use ML/AI in digital health and well-being solutions, and even what solutions matter in the first place? In this talk, I will discuss participatory approaches to designing digital health and well-being technologies with patients, family members, and clinicians.  Starting with field studies in clinics exploring how people navigated use of a deployed, diagnostic AI system, and moving onto examples of responsibility AI practices, I will discuss participatory approaches and their importance throughout the technology design, development, and evaluation process.

• BBL Speaker Series: (Some) things I worry about in HCI/CSCW research

  Date: Dec 1st, 2022 12:30 PM
  Speaker: Dan Cosley, Program Officer, National Science Foundation
  
  Location: HBK 2105
  
  Abstract: In this talk, rather than report out on some research that I'm involved with, I plan to do some meta-reflection on things that I worry reduce the contribution and impact of research in HCI, CSCW, and related areas. I tentatively plan to focus on four main issues, based both on work I've been involved with myself and on other studies I've seen:
  
  

  • Our Methods Make Us Dumb (Other People Know Things)
  • Whither the Artifact? (Goldilocks and the Three Stances)
  • Things Change (Tweet, Tweet… Musk!); and
  • Failure To Generalize (A Grounded Theory of X?)

  I haven't given a talk like this before, and many of the issues have already been observed in some form by people smarter than me, but I think there's value in bringing them together and hope that talking about this will be useful for both HCI practice and HCI research. I plan to have the talk itself run a little short so we can have a more interactive discussion, so feel free to bring a few of your own worries along to share.

Finding the Grammar of Generative Craft

Abstract: Art and craft design is challenging even with the assistance of computer-aided design tools. Despite the increasing availability and intelligence of software and hardware, artists continue to find gaps between their practices and tools. Through this presentation, I introduce Grammar-driven Craft Design Tools (GCDTs), which explicitly embed and utilized craft domain knowledge as their primary mechanisms and interfaces. Besides bridging the gap between design-aid tools and craft domain knowledge, GCDTs also have additional benefits such as supporting generative design, facilitating learning, and preserving domain knowledge. This talk discusses how the next generation of design-aid tools can help artists find their creative expressions.

Bio: Licia He is a generative artist and a human-computer interaction researcher. After receiving her Ph.D. from the School of Information, University of Michigan, Licia is currently an assistant professor at the Department of Visualization, Texas A&M University, where she leads the Generative Craft Lab.

Everyday stress management technology “in the wild” towards equitable wellbeing computing

Abstract: In this talk, I discuss my work in stress management sensing and intervention technologies for everyday use, i.e. that can be widely adopted by the entire population. I present stress as an example and introduction to equitable wellbeing computing focused on the design, building, and evaluation of affordable, engaging, and efficacious ubiquitous computing technology enabling the equal widespread of wellbeing. I delve in detail into examples of both sensors and interventions that can enable this vision.
First I discuss “sensorless” sensing as an approach to repurposing existing data and infrastructure to obtain continuous, longitudinal stress data that is informed by sound theory on biomechanics. Then I describe an intervention design approach that combines applied machine learning with human-centered design to repurpose engaging attention-grabbing technology (Internet apps, messaging) into personalized just-in-time stress management interventions. My talk finalizes with a future vision on how to take wellbeing computing research out of the lab and “in the wild”, how to manage “shared autonomy” challenges between humans and automated wellbeing systems, and how to focus on embedding ethical principles in the design of these modern systems.

Considering Users’ Basic Psychological Needs in Technology Design

Abstract: Users’ needs should be at the center of new technology design and development efforts. Nonetheless, there is a big gap in current research surrounding basic psychological need fulfillment. According to the Basic Psychological Needs Theory, the satisfaction of our basic psychological needs is necessary for autonomous motivation: if our needs, namely autonomy (desire to have control over our actions), competence (innate desire to experience mastery) and relatedness (desire to care for others and be cared for in return) are fulfilled, we are motivated to engage in a task. If the needs are not fulfilled, our well-being is negatively affected. In the past, basic psychological needs were measured to explain motivation for task engagement in the workplace, education and sport sector but there is little research drawing a link to technology usage and interaction. However, especially with the growing use of technologies in our daily lives, their increasing autonomy and competence in executing tasks, and their role in virtual communication, it is crucial to assess users’ need satisfaction to ensure their well-being when interacting with new technologies. My research focuses on design factors that positively influence users’ basic psychological needs. I will present several studies that address design factors, individual differences in need satisfaction, and the importance of basic psychological needs for technology acceptance.

Understanding Social Media Usage related to Cognitive Disabilities in the Arabic World

Abstract: Social media has become a desirable means for spreading awareness, advocating for rights, establishing communities, acquiring information, and much more. Studies confirmed the substantial value of social support and community belonging for individuals with disabilities and their caregivers. Users in the Arabic world have shown an increasing interest in using social media in the past decade. However, there is limited research that investigated how social media was used in the Arabic world to support people with cognitive disabilities and advocate for their rights. We tried to start filling this gap through a two-stage project. In the first stage, we interviewed caregivers and teachers for children with cognitive disabilities from Saudi Arabia to examine their motivations and concerns around using social media in relation to their children or students’ conditions. We found that caregivers used social media with caution to seek information and emotional support, to spread awareness, and to communicate and build communities. In the second stage of the project, we applied text mining approaches, including sentiment and temporal analyses, on Arabic tweets related to cognitive disabilities during a nine year period. Content volume, temporal evolution, user accounts, sentiment, and topics of the tweets were analyzed. The results provide new insight into public perspectives, which may assist interested entities to form and distribute appropriate resources and information.

Personal Informatics in the Changing, Social World

Abstract: Personal informatics refers to information individuals can collect about themselves, such as food intake, physical activity, sleep, and mood. Current personal informatics tools have been designed primarily for personal use, focusing on quantitative measurements that are easy to collect via sensors or manual input. These systems often overlook the changing nature of everyday life, the social contexts individuals live in, the variety of goals and values they have, and the constraints and preferences associated with these contexts and values. My research has examined the collaborative use of personal informatics data and co-constructed experience in various contexts. In this talk, I will share a few recent studies unpacking ways to rethink personal informatics technology that considers the changing contexts of health behavior, shifting values and priorities, as well as the social roles and relationships that often deeply intertwine with health decisions.

Designing to Introduce Technological and Algorithmic Bias in Computing Lessons

Abstract: Technology is ubiquitous in modern society. It affects our daily activities and exists in every household and on every street corner. Yet, research has shown that both the process of creating technologies and the technologies themselves are biased. New technologies are based on datasets, algorithms, and designs that encode developer and data biases. As youth increasingly use technologies in their daily lives, experience the effects of technologies and algorithms, and learn to be technology creators, it is important for them to critically explore and understand the ways that technology introduces and perpetuates inequities. In this talk, I present a design study on the development and implementation of materials specifically designed to teach about Threats to Techquity. Threats to Techquity are aspects of computing and technologies that cause or could cause inequalities, especially inequalities based on marginalized identities (e.g., inequalities due to race, immigration status, gender, sexual orientation, ability). To understand how to bring Techquity into the classroom, I partnered with youth and teachers using participatory design to develop the “Talking Techquity” curriculum for middle grades (5th through 8th grade) students. Findings from this work revealed: (1) youth initially named and identified examples of visible Threats to Techquity, but as they learned more about these threats, they uncovered and discussed invisible Threats to Techquity more frequently and identified these threats as important topics to be taught to peers; (2) youth and teacher designers had similar instructional priorities and utilized similar pedagogical strategies when designing and critiquing learning experiences about online data collection and data use, but had contrasting ways of discussing examples and different learning goals; and (3) when implementing “Talking Techquity,” teachers who helped co-design the curriculum made adaptations to content and project requirements to provide more scaffolding and ensure students experienced success based on teachers’ perceptions of student needs and other factors. This research encourages researchers, curriculum designers, educators, and students themselves to consider how to teach about the Threats to Techquity affecting youth’s daily lives and demonstrates how participatory design methods can help uncover key conceptualizations and instructional priorities that make this possible.

Human-Centered AI: Ensuring Human Control, Enhancing Human Performance

Abstract: A new synthesis is emerging that integrates AI technologies with Human-Computer Interaction to produce Human-Centered AI (HCAI). Advocates of this new synthesis seek to amplify, augment, and enhance human abilities, so as to empower people, build their self-efficacy, support creativity, recognize responsibility, and promote social connections. Researchers, developers, business leaders, policy makers and others are expanding the technology-centered scope of Artificial Intelligence (AI) to include Human-Centered AI (HCAI) ways of thinking. This expansion from an algorithm-focused view to embrace a human-centered perspective, can shape the future of technology so as to better serve human needs. Educators, designers, software engineers, product managers, evaluators, and government agency staffers can build on AI-driven technologies to design products and services that make life better for the users. These human-centered products and services will enable people to better care for each other, build sustainable communities, and restore the environment. The passionate advocates of HCAI are devoted to furthering human values, rights, justice, and dignity, by building reliable, safe, and trustworthy systems. The talk will include examples, references to further work, and discussion time for questions. These ideas are drawn from Ben Shneiderman’s new book Human-Centered AI (Oxford University Press, February 2022). Further information at: https://hcil.umd.edu/human-centered-ai

Building customizable and collaborative AI assistants

Abstract: AI assistance is an increasingly widespread approach to improving knowledge work. However, most commercial AI assistants today offer users limited customization options, making them difficult to integrate in specific workflows. You might be able to change its voice or superficially integrate it with other apps, but what if you wanted to teach it complex new skills (e.g. formulating research questions, connecting ideas, putting together counterarguments, etc.)? In this talk, I will describe two prototypes which explore this question. Dual is an experimental AI assistant whose skills are entirely defined by users through a lightweight scripting language which extends prompt engineering with variables and nested calls. However, even if customizable skills are handy in tailoring an AI assistant’s skill set to the user’s needs, knowing when to use what skill remains challenging. You might only have a broad overarching goal (e.g. learning a concept, solving a problem, making a decision, etc.) whose translation to individual replies is non-trivial. As an early step in addressing this challenge, I will introduce Oneironomicon, a conversational sandbox for training AI assistants on “dreamed-up” user simulators using reinforcement learning before repurposing their know-how to help real users.

Bio: Paul is a Romanian-born Netherlands-based student exploring ways of augmenting human cognition using AI. On the surface, this happens by designing tiny new primitives, mechanics, and affordances which symbiotically bring together minds and machines. On a deeper level, this happens by putting together a cognitive infrastructure: a patchwork of building blocks which together enable a rich combinatorial space of thought patterns, both organic and artificial, both individual and collective.

From content moderation to school assignment: What do theories of justice teach us about design?

Abstract: Computational systems have a complex relationship with justice: they may be designed with the intent to promote justice, tasked to resolve injustices, or actively contribute to injustice itself. In this talk I will take two theories of justice, restorative and distributive justice, as frameworks to analyze and imagine alternatives to two real-world systems. First, I will analyze online harms such as harassment and revenge porn and how they are currently addressed through content moderation. I will use restorative justice to discuss the shortcomings of content moderation to effectively address those harms and discuss what alternatives we might design. Second, I will analyze an attempt at using computational systems to promote distributive justice in public schools in San Francisco that ultimately failed to achieve its theoretical promises of transparency, equity, and efficiency. I will show how incorrect modeling assumptions about families’ priorities, constraints, and goals clashed with the real world causing the algorithm to fail. Through this work I argue for recognizing the limitations of algorithmic solutions, broadening how we evaluate computational socio-technical systems, and ongoing engagement with those affected by those systems.

Fake-News Network Model: A Conceptual Framework for Strategic Communication to Deal with Fake News

Abstract: This article analyzes the entire life span of a corporate fake-news report as a case study, proposing a conceptual framework for strategic fake-news communication. Using the confirmation-bias theoretical model, this qualitative textual analysis examines the most widely circulated tweets of a fake-news item about Nike, 603 replies to the tweets, users’ biographical profiles (e.g., political affiliations), the role of opinion leader(s), and relevant prior contexts. The findings provide in-depth insight into how people believe fake news and how their conversations about fake news (re)shape the victim brand’s social realities. Overall, the findings of this study illustrate a “Fake-News Network Model” that explains the underlying mechanisms of how a fake-news item functions together with other aspects (e.g., context, perception, opinion leaders, and cognitive processes), prompting certain people to believe particular fake-news reports and, discuss the victim brand (e.g., Nike) based on that perceived truth. The article discusses the implications of this network model for both fake-news researchers and strategic communication professionals.

AI-powered Interaction: Principles, Models, and Applications

Abstract: How to leverage AI to enhance and augment users’ interaction with computers is a grand challenge. In this talk, I will use text-based communication in Post-PC computing as an example to demonstrate how to integrate AI into interactive systems. We have created multiple AI-powered writing systems that can (1) infer users’ communication intention from noisy input such as eye gaze, voice, and finger touch, and (2) adapt to individuals and support text input on invisible and imaginary keyboards, and (3) detect whether users develop early signs of Parkinson’s Disease. The secret ingredient behind these AI-powered interactive systems is probabilistic modeling: we have created probabilistic models to quantify uncertainty in interaction, and adapted Bayesian inference as a principle of resolving uncertainty in interaction and integrating multimodal input.

2/4 | Pardis Miri
— Facilitating Affect Regulation Using a Vibrotactile Technology

[Recording]

Abstract. Dr. Miri will discuss her work on designing vibrotactile technologies to facilitate affect regulation. Specifically, she will cover how she designed, engineered, and evaluated a vibrotactile breathing pacer to help with stress reduction in a population of young college students. She will discuss whether the pacer was effective in anxiety reduction (both in self report and psychophysiology measures) and, where effective for whom it was effective (e.g., for those low on Big Five Openness, the device was more effective). She will then discuss how she built on the knowledge gained from a college student population, and is currently targeting her research for children diagnosed with autism spectrum disorder.

Bio. Pardis Miri, PhD, is a postdoctoral fellow at Stanford University, where she is working at the intersection of human computer interaction and affective science. Such research is highly interdisciplinary, and involves computer systems, human-computer interaction, psychology, and behavioral science. She is being advised by Professor Keith Marzullo at the University of Maryland iSchool, whose research is on distributed systems, and by Professor James Gross, whose research underlies much of what we now know about emotion regulation. She is also working with Professor Antonio Hardan of the Stanford School of Medicine, whose research is on children with Autism Spectrum Disorder.
Dr. Miri leads a multidisciplinary research team in the Stanford Psychophysiology Lab (the WEHAB team) aimed at the design, engineering, and evaluation of technologies to help people to successfully manage their emotions, moods, and stress responses. She is interested in both neurotypical and neurodiverse populations. Specifically, her work focuses on using theoretically-grounded and data-driven approaches to engineer end-to-end systems that empower people to regulate their unwanted affective experiences and behaviors in their everyday lives. Then, by running carefully-designed clinical experiments, she examines both the average effect (whether the system was effective in changing affect) and the heterogeneous effect (for whom the system was effective). The results of this research will inform practice about what types of interventions are more useful for what type of trait and state individual differences, and will reduce the use of drugs in personalized mental healthcare.

— Automating the News: How Algorithms are Rewriting the Media
[Recording]

Abstract. Amid the push for self-driving cars and the roboticization of industrial economies, automation has proven one of the biggest news stories of our time. Yet the wide-scale automation of the news itself has largely escaped attention. In this rapidly shifting terrain, Nicholas Diakopoulos focuses on the people who tell the stories—increasingly with the help of computer algorithms that are fundamentally changing the creation, dissemination, and reception of the news.
Diakopoulos reveals how machine learning and data mining have transformed investigative journalism. Newsbots converse with social media audiences, distributing stories and receiving feedback. Online media has become a platform for A/B testing of content, helping journalists to better understand what moves audiences. Algorithms can even draft certain kinds of stories. These techniques enable media organizations to take advantage of experiments and economies of scale, enhancing the sustainability of the fourth estate. But they also place pressure on editorial decision-making, because they allow journalists to produce more stories, sometimes better ones, but rarely both.

Bio. Nicholas Diakopoulos is an Associate Professor in Communication Studies and Computer Science (by courtesy) at Northwestern University where he directs the Computational Journalism Lab. He is also a Tow Fellow at Columbia University School of Journalism as well as Associate Professor II at the University of Bergen Department of Information Science and Media Studies. His research focuses on computational journalism, including aspects of automation and algorithms in news production, algorithmic accountability and transparency, and social media in news contexts. He is author of the book, Automating the News: How Algorithms are Rewriting the Media, published by Harvard University Press. Recently he was a resident researcher in the Computational Political Journalism Lab at the Washington Post. He received his Ph.D. and M.S. degrees in Computer Science from the School of Interactive Computing at the Georgia Institute of Technology, and his Sc.B. degree in Computer Engineering from Brown University.

— Information Integration Theory and the Human-Computer Interface

[Recording]

Abstract. Information Integration Theory (IIT) was developed in the 1960’s by Norman H. Anderson. It is a comprehensive theory on how people assess information of different types from different sources to form an overall judgment or decision.  It has been used to scale information, determine the integration function, and measure the weighting of factors of information.While I was trained in IIT as a graduate student at the University of Iowa and a post doc  at UCSD with Anderson and published numerous studies in the 70’s and 80’s, I failed to truly carry it through to research in HCI and more recently the psychology of video games. In atonement, I present this talk and propose new research methods using the experimental designs of IIT to reap the benefits of IIT in human-computer interaction.

Bio. Kent L. Norman (https://en.wikipedia.org/wiki/Kent_Norman) received his doctorate from the University of Iowa in Experimental Psychology, 1973.

— The Colorectal Cancer Risk Assessment Tool: A Case Study

[Recording]

Abstract. The Colorectal Cancer Risk Assessment Tool redesign project is a good, albeit rare, example of a “soup-to-nuts” project.  The project was conducted by the Human Factors Engineering firm I direct, for the National Cancer Institute .  It involved literature research, interaction design, and iterative design as well as both qualitative and quantitative evaluations.   After describing multiple interactive visualization designs we will discuss evaluation results and show a demonstration of the final implementation. The origin of the project provides some insight into when and how user experience design issues become the focus of a project in the corporate world. Sadly, it also shows when and how user experience design is forgotten in the corporate world.

— Towards Alignable AIs: Helping humans to better understand, steer, and use deep neural networks

[Recording]

Abstract. As the use of machine learning models in product development and data-driven decision-making processes became pervasive in many domains, people’s focus on building a well-performing model has rapidly shifted to understanding how their model works. Recent years have seen an explosion of interest in understanding how Deep Neural Networks (DNNs) work under the hood and more importantly, how we can adjust the way DNNs work based on our knowledge and expectation. However, DNNs’ architecture offers limited transparency, imposing significant challenges in (1) determining when DNNs make unsuccessful predictions with potential bias and more importantly, and (2) improving the model to make the future behavior align with human expectation. In this talk, I will introduce my approach and vision towards establishing an interactive platform that assists data scientists in steering DNNs in a more cost-efficient, effective, and useful way. At the beginning of the talk, I introduce a formative study that aimed at deeply understanding the current practice of data scientists who apply explainable AI tools in designing, building, and deploying machine learning models. Then I introduce my recent approaches focusing on leveraging interactive attention mechanisms towards empowering users to better steering DNNs in the stage of data collection/annotation and model building stages.

— Portable Laser-Cutting: Transitioning From 1000s of Users to Millions of Users

[Recording]

Abstract. Laser-cut 3D models shared online tend to be basic and trivial—models build over long periods of time and by multiple designers are few/nonexistent. I argue that this is caused by a lack of an exchange format that would allow continuing the work. At first glance, it may seem like such a format already exist, as laser cut models are already widely shared in the form of 2D cutting plans. However, such files are susceptible to variations in cutter properties (aka kerf) and do not allow modifying the model in any meaningful way. I consider this format machine specific. I tackled the challenge by writing software tools to modify 2D cutting plans, replacing non-portable elements with portable counterparts. This makes the models portable, but it is still hard to modify them. I thustook a more radical approach, which is to move to a 3D exchange format (kyub). This guarantees portability by generating a new machine-specific 2D-cutting plan for the local machine when exported.And the models inherently allow for parametric modifications. Instead, it raises the question of compatibility: Files already exist in 2D—how to get them into 3D? I demonstrate a software tool to reconstruct the 3D geometry of the model encoded in a 2D cutting plan, allows modifying it using a 3D editor, and re-encodes it to a 2D cutting plan. I demonstrate how this approach allows me to make a much wider range of modifications, including scaling, changing material thickness, and even remixing models. The transition from sharing machine-oriented 2D cutting files, to 3D files, enables users worldwide to collaborate, share, and reuse. And thus, to move on from users creating thousands of trivial models from scratch to collaborating on big complex projects.

4/29 | Alex Leitch — Glitch As Interface

Abstract. When designing interfaces, there is an inherent tension between usability and learnability. Come and consider how style and breakage play into this tension by encouraging and then undermining user trust, and how expert users may take greater ownership over devices by working with breakage to make unique interactions. We will explore the promises of the most common interaction design grammars and contrast them with familiar grammars of other types of screen-based interaction, examining the role played by game feel, and how a play-oriented perspective can decompose a skilled, planned experience into alternate, client-driven use cases. TL:DR; people find their own uses for things, let’s see how that works with screen-based experiences.

Bio. Alex Leitch is a technology consultant and artist whose work focuses on interaction design. As an artist, they have exhibited at the Toronto International Film Festival, multiple galleries, and installation festivals such as Gladstone Hotel’s Come Up To My Room, Ontario Place’s Winter Lights, and the Burning Man festival.

10/8 | Sarah McGrew
— Who is Behind This? Teaching Students to Evaluate Online Information

Abstract. Young people often turn to the Internet for information, where they face nearly constant questions about what to trust. In this talk, I will argue that educational innovations are a necessary component of efforts to combat the spread of online mis- and disinformation. However, few research-based resources exist to support teachers and students to learn to effectively evaluate online information. I will outline a curricular approach designed to teach strategies that professional fact checkers use to evaluate online sources and explore students’ progress in learning these strategies with findings from a series of intervention studies in high school and college classrooms. I’ll discuss possibilities and hurdles for teaching evaluation strategies and consider how technological solutions might accompany educational innovations.

Bio. Sarah McGrew is an Assistant Professor in the College of Education at the University of Maryland, College Park. Her research focuses on young people’s civic online reasoning—how they search for and evaluate online information on contentious social and political topics—and how schools can better support students to learn effective evaluation strategies. Dr. McGrew has developed assessments of students’ online reasoning, conducted research on fact checkers’ strategies for evaluating digital content, and tested curriculum designed to teach these strategies to secondary and college students. In addition to investigating online reasoning curricula in secondary and college classrooms, Dr. McGrew’s current research focuses on how best to support teachers to learn online reasoning themselves and how to design lessons in online reasoning that are rooted in civic and community issues that students know and care about. She has a Ph.D. in Curriculum and Teacher Education from Stanford University and previously taught high school history in Washington, DC.

10/15 | Karen Holtzblatt — The Jerk Project

[Recording]

Abstract. The Valuing and Jerk Project.
For the last 40 years we’ve been encouraging women to choose technology careers. But today the quit rate for women in tech is 41% compared to 17% for men. The number of WIT has fallen from 31% in 1990 to 25% in 2014. Research points to cultural dimensions of tech companies that create a work environment of bias, hostility and devalue. Overall women and people of color report a significantly more negative workplace experience. These interpersonal dynamics create more stress and work against feelings of belonging and value. It is not surprising that our research finds that women “thinking of leaving their job” score lower on key factors necessary for women to thrive.
In this talk Karen shares the research and some of the interventions to identify the explicit behaviors which create or undermine the experience of connection and value in the workplace. Field research identified 15 key valuing and 15 key jerk behaviors. A subsequent survey helped to determine the relative value of each behavior for men and women. We share our data and unveil our interventions including fun awareness posters, a self-assessment checklist, and workshop ideas. All work was done by world-wide professional and student volunteers, including many from UMD.

Abstract. Stroke is a major contributor to adult disability in many countries. Stroke often causes long-term disabilities that affect cognitive, physical, and speech functions. Intensive rehabilitation exercise is critical for stroke recovery during the early stage of a stroke. However, only 31 percent of stroke survivors actually complete the recommended exercises due to a variety of factors including lack of motivation. Working closely with stroke survivors and therapists, we investigated the use of mainstream smart phone-based technology in supporting everyday stroke rehabilitation under the supervision of medical professionals. Rather than using specialized sensors to track user movements, we focused on developing an approach without the need for any additional hardware. ARMStrokes supports customized exercise plans to fit each stroke survivor’s specific functionalities in different recovery stages. Longitudinal evaluations with stroke survivors and therapists suggested the application played positive roles in motivating the patients to complete rehabilitation exercises. Design challenges were also identified through the evaluation studies.

— Towards a grammar for animated data graphics

Abstract. Animated data graphics are becoming popular for data-driven storytelling. However, creating such animated graphics remains challenging and time consuming. In this talk, I will present research results on understanding the design space and authoring paradigms of animated data graphics, and describe our first attempt at designing a tool for authoring animated transitions based on the keyframing paradigm. The ultimate goal of this line of research is to develop a visualization grammar that can power the creation of expressive animated narratives, and provide a foundation for developing authoring and design tools.

— Human-Centered AI: 15 Recommendations for Bridging from Ethics to Practice

[Recording]

Abstract. Human-Centered Artificial Intelligence (HCAI) is a growing theme that seeks to shift the focus from algorithms to the users and many stakeholders in modern information technology systems. This talk and related article (https://dl.acm.org/doi/10.1145/3419764) attempt to bridge the gap between widely discussed ethical principles of Human-Centered AI (HCAI) and practical steps for effective governance. I propose 15 recommendations at three levels of governance: team, organization, and industry. The recommendations are intended to increase the reliability, safety, and trustworthiness of HCAI systems: (1) reliable systems based on sound software engineering practices, (2) safety culture through business management strategies, and (3) trustworthy certification by independent oversight.

— Countering Structural Oppression through Co-design with Residents in Resource-Constrained Communities

[Recording]

Abstract. There has been a recent push in technology design to consider social implications of design — both historical, current, and future. In resource-constrained communities, there have been historical policies and practices (e.g., redlining, overpolicing) that have created concentrated poverty, increased unemployment, and lack of adequate and equitable educational, housing, and health opportunities. However, several local community-based organizations have taken the initiative to address their communities’ challenges regarding issues such as safety and education. In this talk, I will discuss two projects that illustrate how we design technologies, practices, and programs with community residents and organizations to support their efforts to counter social issues that are a result of long-term structural oppression. Specifically, I describe (1) our co-design and evaluation process of a mobile application to support violence prevention efforts by street outreach workers and (2) the evolution of Digital Youth Divas, our program that encourages middle school Black and Latina girls to engage and participate in STEAM experiences. The first project is an example of how to design with organizations that intentionally attempts to counter traditional policing practices by law enforcement by taking a community-led approach to public safety in neighborhoods that experience high violence. The second project illustrates how we can address policies and infrastructure that create barriers for Black and LatinX girls and their families to engage in informal learning opportunities. Insights lead to discussion regarding how we as designers can intentionally support community-based counter structures to make a long-term, sustainable impact on communities that have historically faced systemic oppression.

Bio. Dr. Sheena Erete is an associate professor in the College of Computing and Digital Media at DePaul University. Her research explores the role of technology and design in addressing social issues such as violence, civic engagement, and STEM education in resource constrained communities in Chicago.

— There’s no AI in Team: Evaluating Systems for Multiple-Human Interaction

Abstract. As AI systems become increasingly common, they will need to become more useful and usable as well. One way to make an AI more usable is to embed it into a team structure. Current research on AI-enabled teams generally focuses on functional requirements for the AI, such as task performance or levels of operator intervention required. However, AIs must be designed to optimize the outcomes of the entire sociotechnical system, or else gaps may lead to failures. Looking into the future, AI systems created to assist humans will need to be designed to work with humans, or within human teams. We do not argue that AI systems in human teams need to be human-like, but there are particular behaviors and non task-related requirements that are necessary for them to operate harmoniously as part of a team. This research effort uses a novel input-process-emergent state-output-input (IPEOI) model with four levels to describe what is needed for AI-enabled team performance. In this talk, I will describe the work our multidisciplinary team has done to define the problem of AI-human teaming and provide a preliminary look at our proposed model. This work has been done in collaboration with Breana Carter-Browne (ARLIS), Susannah Paletz (iSchool), Melissa Carraway (iSchool PhD student), Sarah Vahlkamp (iSchool PhD student), Jana Schwartz (ARLIS), and Polly O’Rourke (ARLIS).

— The Impact of Tool Design and Media Portrayals in the Success of Activist DDoS Attacks
[Recording]

Abstract. This talk explores the role of tool design and media coverage in the relative success of Operation Payback and earlier activist distributed denial-of-service (DDOS) actions. Through a close reading of changes in the tool’s interface and functionality across several iterations, the article considers the evolution of the Low Orbit Ion Cannon (LOIC) DDOS tool, from one that appealed to a small, inwardly focused community to one that engaged with a larger population. The article further considers Anonymous’s contribution to the reframing of DDOS actions from a tool of direct action to a tool of media manipulation and identity construction as well as the news media’s role in encouraging individuals to participate in the Operation Payback actions.

The User Experience of Viewing Captioned Content
Much has been made of the ability of automatic speech recognition (ASR) to supplement or replace human captioners both for video content and for live meetings. While the word error rate of ASR has been steadily improving, and on some types of content can even beat out human captioners, these improvements do not automatically in a good user experience for people who are deaf or hard of hearing. In this talk we will examine the reasons why this is so, and provide an overview of current efforts to develop human-centered caption quality metrics that are more closely aligned with meeting the needs of people who depend on captions to consume content.

Promoting Pro-social Behavior with End-to-End Data Science
The recent development of data science methods, including large-scale machine learning and causal inference, has presented a game-changing opportunity for social good provision through the effort of the crowd. In this talk, I introduce an end-to-end data science pipeline to promote behavioral change for pro-social benefits. More specifically, this involves conducting causal data analysis on empirical data for actionable insights and robust prediction models, incorporating the insights and predictions in designing recommender systems for individual actions, and evaluating the effectiveness of the recommender systems in promoting behavioral changes with randomized field experiments. I will present two applications of the end-to-end pipeline, where we designed and deployed team recommender systems on an online microfinance platform (Kiva.org) and a ride-sharing platform (DiDi). We evaluated the recommender systems through large-scale field experiments, which show significant increases in user participation. The recommender system has been deployed in DiDi and has impacted millions of users in practice.

Quantifying Human Performance and the Quality of Immersive Experiences
Psychometric evaluations are generally used to understand the Quality of Experience (QoE) of immersive environments produced using augmented/mixed/virtual reality. Typically, these subjective evaluations are done from an end-user point-of-view, but these are limited by the subjective observations due to a number of factors. The objective approach consists of measuring the QoE by monitoring the network technical parameters or the network Quality of Service (QoS), such as throughput, delay, and packet loss. Most of the research on objective approaches for QoS-QoE mapping have focused on video streaming. Such objective QoS-QoE mapping strategies cannot be directly applied for immersive environments. Hence, in this talk, we address two related questions: (1) Can we identify metrics that can objectively quantify the performance of an immersive environment? (2) Can we use the above objective performance metrics to understand the possible user QoE without the need for subjective user study or with minimal user study? We start with different examples of immersive environments such as haptic-enabled applications, mirror therapy, and games. We discuss what metrics are influenced by different system parameters such as processing power, and network QoS. Then, we present some of our preliminary work on understanding users’ QoE through these metrics.

Celestial: Color Patterns for improving Color Perception for blind people.
It is relatively difficult to recreate the abstract three-dimensional shape with only the tactile sense. Gibson said “These abilities can be improved through practice.” “When you touch something, You may have no idea about it at first touch, but as you continue touching, you soon will know vaguely what it is” , Kojiro Hirose said.

Recently, we developed “Blind-touch” to aid the visually impaired to appreciate greater painter’s work of art. This work is a reproduction of an existing masterpiece by means of a 3D printer and haptic electronics. It recognizes the pattern by touching the object in the artwork with a fingertip, and voice explanation and sound effect are provided through the voice user interface. Color is an equaling lens through which we experience the natural and digital realities. Now, we are exploring the tactile-color association based on semiotics to represent colors with fingertip tactile sensation. In this way, audio and touch contribute information to the non-visual perception of color in an complementary manner. In this talk, we review the related works and introduce a so-called “Celestial color tactile pattern” built based on the concept of both pictogram and ideogram and its variants.

Human-Centered Artificial Intelligence: Designing Next Generation User Experiences
The next generation of user experiences will produce 1000-fold improvements in human capabilities. These new tools will amplify, augment, enhance, and empower people, just as the Web, email, search, navigation, digital photography, and many other applications have already done. These new human-centered tools will produce comprehensible, predictable, and controllable applications that promote self-efficacy and social participation at scale. The goal is to ensure human control, while increasing the level of automation. In short, the next generation of tools will make more people, more creative, more often.
Improved designs will give billions of users comprehensible interfaces that hide the underlying complexity of advanced algorithms. Users will see familiar visual strategies based on direct manipulation to provide informative feedback about the machine’s state and what they can do. Every use will build confidence that users can reliably accomplish their goals and increase the trust that the machine is under their control.

MakeCode and CODAL: intuitive and efficient embedded systems programming for education
Across the globe, it is now commonplace for educators to engage in the making (design and development) of embedded systems in the classroom to motivate and excite their students. This new domain brings its own set of unique requirements. Historically, embedded systems development requires knowledge of low-level programming languages, local installation of compilation toolchains, device drivers, and applications. For students and educators, these requirements can introduce insurmountable barriers.
We present the motivation, requirements, implementation, and evaluation of a new programming platform that enables novice users to create software for embedded systems. The platform has two major components:
1) Microsoft MakeCode (www.makecode.com), a web app that encapsulates an entire beginner IDE for microcontrollers; and
2) CODAL, an efficient component-oriented C++ runtime for microcontrollers.
We show how MakeCode and CODAL provide an accessible, cross-platform, installation-free programming experience for the BBC micro:bit and other embedded devices.

Towards Automated Fact Discovery and Ranking
In this talk, I present the work of finding new, prominent situational facts, which are emerging statements about objects that stand out within certain contexts. Many such facts are newsworthy—e.g., an athlete’s outstanding performance in a game, or a viral video’s impressive popularity. Effective and efficient identification of these facts assists journalists in reporting, one of the main goals of computational journalism. A situational fact can be modeled as a “contextual” tuple that stands out against historical tuples in a context, specified by a conjunctive constraint involving dimension attributes when a set of measure attributes are compared. New tuples are constantly added to the table, reflecting events happening in the real world. Our goal is to discover constraint-measure pairs that qualify a new tuple as a contextual significant tuple, and discover them quickly before the event becomes yesterday’s news.

Diversity in Matching Markets
In bipartite matching problems, vertices on one side of a bipartite graph are paired with those on the other. In its offline variant, both sides of the graph are known a priori; in its online variant, one side of the graph is available offline, while vertices on the other arrive online and are irrevocably and immediately matched (or ignored) by an algorithm. Examples of such problems include matching workers to firms, advertisers to keywords, organs to patients, and riders to rideshare drivers. Much of the literature focuses on maximizing the total relevance—modeled via total weight—of the matching. However, in many real-world problems, it is also important to consider the contribution of diversity: hiring a diverse pool of candidates, displaying a relevant but diverse set of ads, and so on.

In this talk, we model the promotion of diversity in matching markets via maximization of a submodular function over the set of matched edges. We present new results in a generalization of traditional offline matching, b-matching, where vertices have both lower and upper bounds on the number of adjacent matched edges. We also present new theoretical results in online submodular bipartite matching. Finally, we conclude with ongoing work that approaches the problem of hiring a diverse cohort of workers through the lens of combinatorial pure exploration (CPE) in the multiarmed bandit setting, and discuss an ongoing experiment in this space at a large research university.

This talk will cover joint work with Saba Ahmadi, Faez Ahmed, Samsara Counts, Jeff Foster, Mark Fuge, Samir Khuller, Zhi Lang, Nicholas Mattei, Karthik A. Sankararaman, Candice Schumann, Aravind Srinivasan, and Pan Xu.

What is Valuing vs “Jerk” Behavior? How behavior impacts a positive working experience
Women in tech leave the field at twice the quit rate as men. Women often state, and research confirms, that women don’t feel valued. They point to the culture of the organization and how they are treated as a contributing factor. They say that men are “bro’s” or “jerks.” In 2018, we launched the Valuing & Jerk Project as one WITops initiative (https://www.witops.org). This talk will present our findings and perspective. Behavior creates or undermines connection and value. The Valuing and Jerk Project focuses on understanding which behaviors are experienced as valuing in everyday work and which result in naming the other as a “jerk”. Using Contextual Inquiry, we have uncovered core valuing behaviors, what devaluing means, and where behavior crosses the line to become “jerk” behavior. Armed with this understanding our next step is to generate and test interventions and solutions. The talk will introduce the Valuing and Jerk Project.

Underestimating the challenge of cognitive disabilities (and digital literacy). Directions to explore in short, medium and long term.
Recent work has caused us to question our understanding of the challenge of digital access by people with cognitive disabilities. Our underestimation may, in part, help explain our difficulties as a field to date. In part, it has exposed what may be a much wider problem than we understood, and one that goes beyond those we have thought of as having cognitive disabilities. It intersects with digital literacy but also has implications for those with other disabilities as well. The concept of Technology Quotient (TQ) will be discussed and approaches for addressing access by people with cognitive disabilities and low digital literacy today, tomorrow and in the future will be explored in this talk.

Human Factors in Mobile Authentication
Mobile authentication is a crucial component of authentication more broadly, especially as mobile devices become evermore connected to the broader computer security ecosystem. The overarching goal of my research is to improve the current state of mobile authentication by taking a holistic approach to measuring mobile authentication and its impacts that intersect directly with the user experience. In this talk, I will present a narrative of contributions to mobile authentication over the last 10 years, focusing on how human factors impact the security, from attacks, choices, and perceptions. I will particularly focus on one form of mobile authentication, Android’s graphical pattern unlock, which may be the most heavily used graphical authentication system, ever. Based on my experience, I will also present some new directions and methods that can improve the security of mobile authentication and some new results on PINs and LG’s graphical Knock Code Authentication.

Storytelling makes research data come to life
We all love our user research data…but why is it such a struggle to use the insights we uncover to create direction for a project? Storytelling is the missing link, getting past charts and graphs to dig into what the data means for meeting human needs and making something usable and useful. Whitney will show how stories put research insights into context, communicate the entire user journey, show problems through the eyes of your users, and help you ask better questions (and run better usability tests) to gain deeper insights. Whitney is the co-founder of the Center for Civic Design, approaching democracy as a design problem, so there will be examples from the challenges of designing elections as well as stories from her work in theatre.

Design Democratization in the Age of Machine Learning.
Design democratization can transform the way we think about designing products. However, to enable design democratization, we need machine learning and computing methods to enable organizations to process a large amount of information efficiently. Using the example of online design contests, we will discuss three problems which organizations face in conducting design contests: a) How does one form teams to evaluate design ideas? b) How does one filter high quality and diverse ideas out of hundreds of submissions? and c) How does one reliably measure the creativity of ideas? We will discuss how matching, ranking, and novelty estimation methods developed in our work address these issues and what challenges remain for the field.

Interactive Fabrication and Fabrication for Interaction.
3D printing technology has been widely applied to produce well-designed objects. There is a hope to make both the modeling process and printing outputs more interactive, so that designers can get in-situ tangible feedback to fabricate objects with rich functionalities. To date, however, knowledge accumulated to realize this hope remains limited. In this talk, I will present two lines of research. The first line of work aims at facilitating an interactive process of fabrication. I demonstrate novel interactive fabrication systems that allow the designer to create 3D models in AR with a robotic arm to print the model in real time and on-site. The second line of work concerns the fabrication of 3D printed objects that are interactive. I report new techniques for 3D printing with novel materials such as fabric sheet, and how to print one-off functional objects such as sensor and motor. I will conclude the talk by outlining future research directions built upon my current work.

Everyone a Data Scientist: Empowering Casual Users to Understand Complex Data.
Understanding data is quickly becoming the new digital divide. Merely having access to information and communication technologies (ICTs) is no longer sufficient when our society is overflowing with massive volumes of raw, complex, and heterogeneous data. Since best-practice data science workflows are still only available through esoteric software libraries, typically accessed using the Python and R languages, leveraging this data to its full potential often requires significant programming expertise. Even commercial point-and-click analytics tools such as Tableau, Spotfire, and QlikView require training and assume significant prior knowledge of mathematical, statistical, and sometimes even machine learning concepts. This means that currently only people who have the appropriate data and technology literacy can harness the ready availability of data in our society.

In this work-in-progress talk, I will discuss our efforts for shrinking or outright eliminating this new digital data divide through interactive visualization, explainable machine learning, and collaborative technologies. More specifically, I will talk about several past, current, or planned projects on this topic, including (1) the use of mixed-initiative interaction, which combines both human and computational efforts in the analytical process; (2) the use of attention for computational steering; (3) recommender systems for automatically suggesting the next analytical step in a workflow; (4) direct manipulation methods for interacting with machine learning models; and (5) “team-first” collaborative mechanisms that reduce the barrier to synchronizing and sharing work to facilitate emergent collaboration. This is ongoing research, so your feedback on these efforts is welcome.

Join, Stay or Go? Members’ Life Cycles in Online Health Communities
This talk discusses temporal changes in members’ participation in online health community (OHC), focusing on their motivations for joining and changes in their motivations as they transition to other roles or ultimately leave the community. We use mixed methods, combining behavioral log analysis, automated content analysis, surveys and interviews. We found that members started participating in OHCs for a common set of reasons, mainly to acquire support and to perform social comparisons. When their need for support decreased, most members quit the site. The motivations of those who stayed shifted to providing support and helping other members in the community. Oldtimers also established social ties with others members, which motivated them to stay in the community. These oldtimers, who contributed the majority of content, encountered challenges that threatened their commitment to the community, including negative emotion related to other members’ deaths. These challenges led them to take leaves of absence from the community or to drop out permanently. Our findings shed light on the changing motivations of OHC members, which provide implications for better designing OHCs.

ORC Layout: Adaptive GUI Layout with OR-Constraints
We propose a novel approach for constraint-based graphical user interface (GUI) layout based on OR-constraints (ORC) in standard soft/hard linear constraint systems. ORC layout unifies grid layout and flow layout, supporting both their features as well as cases where grid and flow layouts individually fail. We describe ORC design patterns that enable designers to safely create flexible layouts that work across different screen sizes and orientations. We also present the ORC Editor, a GUI editor that enables designers to apply ORC in a safe and effective manner, mixing grid, flow and new ORC layout features as appropriate. We demonstrate that our prototype can adapt layouts to screens with different aspect ratios with only a single layout specification, easing the burden of GUI maintenance. Finally, we show that ORC specifications can be modified interactively and solved efficiently at runtime.

One of the most valuable parts of the DNA of HCIL is its focus on “human”, and how our mentors guide us to connect our work with people (users). As a student of this school of thought, I had found my purpose to help the 95% by identifying, questioning, and removing barriers (creating opportunities) in visual analytics. Two years ago, with results baked in lab, and the same driving purpose, I stepped into a world unknown to me: creating, running, and growing a business, one customer at a time.

I am back to share some of the surprises, new perspectives, and validations from this journey so far. What I missed can help you realize the opportunities you already have. What I wish I knew may reveal some gaps. And, what remained constant may hint that research in university and what comes after may not be so different after all. I also will touch on the subtle and dynamic balance between your elevator pitch, your audience, the value you provide, and crossing the finish line.

Brian’s paper talks about Evaluating Visual Comparison and seeks to understand how different encodings of data can drastically affect how we perceive quantities. More information about this project is available at https://hcil.umd.edu/visualcomparison/.

Karthik’s paper is about a computing platform called Vistrates which seeks to unify the fragmented analytical workflows employed by users to analyze a group of visualizations created in different tools.

Information Olfactation: Harnessing Scent to Convey Data
Olfactory feedback for analytical tasks is a virtually unexplored area in spite of the advantages it offers for information recall, feature identification, and location detection. We have introduced the concept of information olfactation as the fragrant sibling of information visualization, and this talk will cover our theoretical model of how scent can be used to convey data. Building on a review of the human olfactory system and mirroring common visualization practice, we propose olfactory marks, the substrate in which they exist, and their olfactory channels that are available to designers. To exemplify this idea, we present viScent: A six-scent stereo olfactory display capable of conveying olfactory glyphs of varying temperature and direction, as well as a corresponding software system that integrates the display with a traditional visualization display, along with three applications that make use of the viScent system.

Learning in the Holodeck: the Role of Multisensory Cues on Pattern Recognition in VR
Designing for multiple senses has the capacity to improve virtual realism, extend our ability to process information, and more easily transfer knowledge between physical and digital environments. HCI researchers are beginning to explore the viability of integrating multisensory media (“multimedia”) into virtual experiences, however research has yet to consider whether mulsemedia truly enhances pattern recognition in virtual reality (VR). In the context of citizen science watershed habitat training, our research asks, how does realism affect observation skills in VR? Within this domain, we build a multisensory system that allows users to feel (wind, thermal, humidity) and smell landscape and environmental conditions. We then compare and report on how users make observations and infer patterns between 2 stream habitats in VR, with and without the multisensory information. Our findings reveal that multisensory information improved the number of high-level, mid-level and low-level observations participants made, and positively impacted engagement and immersion.

A Characterization Study of Exploratory Analysis Behaviors in Tableau
Exploratory visual analysis (EVA) is an interactive process comprising both focused tasks and more open-ended exploration. Visual analysis tools aim to facilitate this process by enabling rapid specification of both data transformations and visualizations, using a combination of direct manipulation and automated design. With a better understanding of users’ analysis behavior, we might improve the design of these visualization tools to promote effective outcomes.
In this talk, I will present our recent work on characterizing the EVA process. We contribute a consistent definition of EVA through review of the relevant literature, and an empirical evaluation of existing assumptions regarding how analysts perform EVA. We present the results of a study where 27 Tableau users answered various analysis questions across 3 datasets. We measure task performance, identify recurring patterns across participants’ analyses, and assess variance from task specificity and dataset. We find striking differences between existing assumptions and the collected data. Participants successfully completed a variety of tasks, with over 80% accuracy across focused tasks with measurably correct answers. The observed cadence of analyses is surprisingly slow compared to popular assumptions from the database community. We find significant overlap in analyses across participants, showing that EVA behaviors can be predictable. Furthermore, we find few structural differences between open-ended and more focused analysis tasks. Finally, I will discuss the implications of our findings for the design of effective data analytics systems, and highlight several promising directions for future study.
