ARCHIVE – Overview

We keep the pages from past projects in a separate Archive.
Also included are pages that are not updated anymore but have an historical value.

The 4 logos of HCIL, from old to new

In particular, our collection of video and research projects contains valuable materials demonstrating pioneer work in Human-Computer Interaction.

The early HCIL Publications and Tech Reports are hosted in the Computer Science department, the original home of the HCIL website.


Past Project Highlights

Read the following introductory short stories that describe the bigger picture of some of our projects

COCO: A Visual Analytics Tool for Comparing Cohorts of Event Sequences

CoCo: A Visual Analytics Tool for Comparing Cohorts of Event Sequences Screenshot

CoCo is a visual analytics tool that enables users to compare two sets of temporal sequence data. It combines automated statistical tests with user-guidance to enable insights, hypothesis generation, and much more. Users see (1) statistics about their dataset, (2) event-level statistics, and (3) a menu of metrics. CoCo displays significance tests in a unified form for measures such as prevalence and duration of gaps.

International Children’s Digital Library Helps Young Readers Worldwide

International Children's Digital Library Screenshot

Libraries have come a long way since Andrew Carnegie’s vision of developing citizenship through increased literacy. Generations have benefited from abundant books in free libraries, purchased with his donated wealth. Times change. Imagine a virtual library of international children’s literature available to kids around the world, created and shared using unique technology. The online International Children’s Digital Library provides a supportive and safe environment for children to communicate with each other, even across language barriers.

ManyLists Screenshot

ManyLists is a product comparison tool that compares products’ features using Spatial Layouts with Animated Transitions. We applied the design concept from our recent comparison tools: Twinlist. It aims to meet the following three goals: 1. Support the comparison of at least four products, each with dozens of attributes. 2. Provide an overview to help users spot products provide more desirable features with less effort. 3. Allow the customization of positive and negative features.

MonoTrans Screenshot

We propose a rethinking of the translation problem to bring together translation technology and human-computer interaction, producing a framework for translation that exploits imperfect technology and limited human abilities in tandem to achieve capabilities neither can achieve alone. The core of this framework is MonoTrans, an iterative protocol in which monolingual human participants work together to improve imperfect machine translations.

Q&A: Supporting Engagement And Peer Learning In A Classroom Setting

Q&A: Supporting Engagement and Peer Learning in a Classroom Setting Screenshot

We are investigating the use of technology to support active student engagement and peer learning in the classroom. We have created a tool called Q&A that allows instructors to pose a question to their students. The students then use Q&A to submit their responses and help aggregate the class’ responses.
