I have been a GRA for Jim Foley since Fall 2004. We have been working on the Human Centered Computing Education Digital Library (HCC EDL). Specifically, I am investigating different ways to support browsing library contents and intertwining the browsing and searching processes more closely. We have created ResultMaps, a visualization system for search result listings, which we use with the HCC EDL search engine.

In collaboration with Sham Navathe and Jim Foley, I have developed ER and relational models that describe extant faceted navigation backing data and query features. Such models are useful for building new systems or frameworks and suggest novel extensions to the state-of-the-art.

As a class project for CS 7470 (Ubiquitous Computing), James Clawson and I conducted a study to investigate how fast people can type using those little QWERTY keyboards (with Kent Lyons and Thad Starner). The results of that and later studies on mini-QWERTY keyboards have been presented at CHI and ISWC.

During Spring and Summer 2004 I did independent research with Ron Arkin on the application of heuristic evaluation to human-robot interfaces and systems.

Between Summer 2004 and Spring 2005, Shwetak Patel and I (advised by Jeff Pierce and Gregory Abowd) investigated interaction techniques enabled by pressures sensors deployed on mobile computing devices (e.g., phones). (pdf)
