Research Projects

Entable The Entable system improves the accessibility of web sites presenting data by introducing table semantic structure. The observational pilot study with visually-impaired internet users studied the potential impact of the introduction of table structure for users of screen reader assistive software. Video SmartWrap The SmartWrap system enables a crowd of end users, explicitly including people who are not programmers, to specify the table semantics of a web data set, and contribute those table semantics to a centralized repository. The SmartWrap system was evaluated with several dozen non-programmers in the lab, as well as remotely using hundreds of participants on Mechanical Turk. Video Mixer The Mixer system lets people quickly and easily accomplish repetitive web data retrieval tasks by demonstrating the required actions on a single row then letting Mixer repeat the demonstrated actions to fill out the rest of the rows of the desired spreadsheet. Mixer was evaluated with several dozen administrators who were not programmers. Video RADAR Space/Time The RADAR Space/Time project studies reasoning under uncertainty in the context of an intelligent assistant helping a user plan a conference with multiple unpredictable venues and attendees.
