Keywords: Ubicomp, activity-based computing, rapid prototyping tools, pen-based user interfaces, programming by demonstration, context-aware computing

I am a Research Associate in the Department of Computer Science and Engineering, working with James Landay. I earned a Ph.D. degree in Computer Science from the Chinese Academy of Sciences, and then did my postdoctoral research in EECS at the University of California at Berkeley.

I am broadly interested in Human-Computer Interaction and User Interface Software Engineering, especially user interface prototyping tools, pen-based user interfaces, ubiquitous computing and programming by demonstration. My current research focus is on design tools for ubiquitous computing applications. In particular, I am using an activity-based approach that is grounded in existing ubicomp design pratice as well as social psychological theories to:

  • streamline a ubicomp design process including field research, analysis, prototyping, and testing,
  • and ground interaction design/computing in both situational factors and the persistent structures of human activity.
I designed and built ActivityDesigner, a system for activity-based ubicomp prototyping.
