I am a Ph.D student in Computer Science program at University of Maryland.

My research interests include Human-Computer Interaction, Ubiquitous Computing, Multimedia and Computer Network. My advisor is Dr. Francois Guimbretiere.

Before I came to U.S in 2001, I spent eight years in Tsinghua University, Beijing, China, where I had so many nice friends and cherishable memories.

Here is where I was born, yanjin, a small town in southwest China and a place haunting in my dream from time to time ...

 

 

Selected Projects:

PaperCP

 

 In line with research integrating physical and digital media, PaperCP explores a paper-based interface for a digital communication infrastructure, Classroom Presenter, in an educational setting. It allows students to enjoy the easy reading, writing, navigation and wonderful tangibility of paper while being able to send written answers on paper to the instructor via underlying computer network. We believe this paper interface can provide better physical-digital trade-off than the original Tablet PC interface for such applications.

Multimodal feedback Pen

 

 The biggest challenge for paper-based interface is the lack of real time feedback. To address this prooblem, we invented this multimodal feedback pen to provide real time pen-top feedback via LEDs, vibration motors and sound/speech for visual, tactile and auditory feedback for interactions on paper.

Butterfly Net

 

 At many times, people simultaneously use digital devices and paper for data capture, for example, in biological field work. A difficulty in this practice is to seamlessly organize and access the data distributed on different media. As a solution, ButterflyNet allows users to link digital pictures in paper notebooks and browse digital data through physical interactions on paper.

PapierCraft

 PapierCraft explores a new approach to bridge paper and computers: Users can use only a digital pen to draw gesture commands on paper documents to manipulate the corresponding digital copies. Not relying on projectors, graphics tablets or any nearby computers, PapierCraft is completely compatible to farmiliar pencil-paper interactions, and provide many more digital functions, which allow you, for instance, to copy-paste on paper, create hyperlink between paper sheets and stich them together !
