Research Areas

The HCIL has conducted a broad range of research over the years, and continues to pursue several areas in depth.  All projects are listed below, and are grouped by area:


Current Projects

Children as Design Partners (Intergenerational Design Teams) Screenshot

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

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

Community Analysis and Visualization Screenshot

Community Analysis and Visualization
Nation of Neighbors is Neighborhood Watch for the 21st century. It facilitates real-time collaboration within communities and between community members and Law Enforcement. Their mission is to enable Citizens and Law Enforcement to work together to fight and deter crime and improve our communities.

Evaluation of Visual Analytics Screenshot

Evaluation of Visual Analytics
The NSF funded SEMVAST project (Scientific Evaluation Methods for Visual Analytics Science and Technology) aims to provide benchmark data sets with ground truth, develop corresponding metrics and automated tools for evaluation, and to seed an infrastructure for the coordination of long term evaluation activities.

EventFlow Screenshot

EventFlow
The HCIL's ongoing work with temporal event records has produced powerful tools for analyzing patterns of point-based events (LifeLines2, LifeFlow). However, users found that point-based events limited their capacity to solve problems that had inherently interval attributes. To address this issue, EventFlow extends its predecessors to support both point-based and interval-based events. With EventFlow, we present novel solutions for displaying interval events, simplifying their visual impact, and incorporating them into meaningful queries.

ManyLists
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. We proposed three guidelines for designing similar Spatial Layouts with Animated Transitions systems: break multi-step processes into small comprehensible steps, show animated transitions for each step, and use spatial layouts to indicate relationships among features.

MonoTrans Screenshot

MonoTrans
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.
