ARCHIVE – Research Projects

The HCIL has conducted a broad range of research over the years, and continues to pursue several areas in depth. Past projects are listed below, and are grouped by area. Current projects can be viewed HERE.

Accessibility

GPII Automated Personalization Computing Project (APCP)
A first large-scale deployment of the Global Public Inclusive Infrastructure (GPII). Approximately 15,000 students and AJC clients, with the full range of ability/disability, literacy, and digital literacy found in these environments, will be provided with access to the GPII auto-personalization. Metrics will be gathered on the reliability, security, privacy, utility, and impact of the GPII, including increased accessibility, reduction in time / effort to configure access, ability to transfer accessibility between environments (home, schools, work), user outlook on self and tech, and impact on education / employment efforts.

Inclusive Design Lab
Our goal is to make the next generation of computing technologies more inclusive. We focus primarily on new mobile and wearable technologies — from touchscreens to head-mounted displays to custom wearable devices — both for broad use as well as for the needs of people with motor or visual impairments. Another thread of our work focuses on the intersection of HCI and machine learning.

Rehabilitation Engineering Research Center on Universal Interface & Information Technology Access
Focused in three areas: (1) Continuing development of the GPII concept – evolving it to address the changing technology landscape and our growing understanding of its role based on discussions with the different accessibility and mainstream stakeholders. (2) Moving the GPII from concept, papers, and laboratory prototypes, through to field implementations where we can test the efficacy and viability of the concept with real-world conditions, users and limitations/realities. (3) Continued work to motivate and facilitate access built directly into mainstream products – through our technology transfer program and our research support of industry standards groups and governmental agencies working on accessibility standards. Included in this project is ongoing work related to EZ Access.

In addition, social interaction and collaboration are essential to the emotional and cognitive development of young children.

Preserving Virtual Worlds
Interactive media are highly complex and at high risk for loss as technologies rapidly become obsolete. The Preserving Virtual Worlds project will explore methods for preserving digital games and interactive fiction. Major activities will include developing basic standards for metadata and content representation and conducting a series of archiving case studies for early video games, electronic literature and Second Life, an interactive multiplayer game.
