ClassSearch: A Classroom Environment for Teaching Web Search Skills
We explore the use of social learning — improving knowledge skills by observing peer behavior — in the domain of Web search skill acquisition, focusing specifically on co-located classroom scenarios. Through a series of interviews,…
Project
SearchBar: A Search-Centric Web History
SearchBar is a system for proactively and persistently storing query histories, browsing histories, and users’ notes and ratings in an interrelated fashion.
Project
SuperBreak: Using Interactivity to Enhance Ergonomic Typing Breaks
Repetitive strain injuries and ergonomics concerns have become increasingly significant health issues as a growing number of individuals frequently use computers for long periods of time. Currently, limited software mechanisms exist for managing ergonomics; the…
Project
Always-Available Mobile Interfaces
We have continually evolved computing to not only be more efficient, but also more accessible, more of the time (and place), and to more people. We have progressed from batch computing with punch cards, to…
Project
AirWave: Non-Contact Haptic Feedback Using Air Vortex Rings
Input modalities such as speech and gesture allow users to interact with computers without holding or touching a physical device, thus enabling at-a-distance interaction. It remains an open problem, however, to incorporate haptic feedback into…
Project
Muscle-Computer Interfaces (muCIs)
We explore the feasibility of muscle-computer input: an interaction methodology that directly senses and decodes human muscular activity rather than relying on physical device actuation or user actions that are externally visible or audible.
Project
Humantenna: Sensing Gestures Using the Body as an Antenna
We use the human body as an antenna for sensing whole-body gestures. Such an approach requires no instrumentation to the environment, and only minimal instrumentation to the user, thus enabling truly mobile applications.
Project
SoundWave: Using the Doppler Effect to Sense Gestures
We present SoundWave, a technique that leverages the speaker and microphone already embedded in most commodity devices to sense in-air gestures around the device.
