I am a first year graduate student in Computers Science and Engineering at the University of Washington. I work with DUB. My temp advisor is James Landay. My research intersts is in human-computer interaction and ubiquitous computing. In particular, I am interested in augmented objects, desing tools, mobile computing, persuasive interface and interactive environments.

I did my undegraduate at National Taiwan Univervisity in Taiwan, where I originally come from. I worked with Ubicomp Lab and my advisor was Hao-hua Chu .

My CV in pdf is here.

Visual Design Tool for context-aware mobile data collection: We feel that sensors combined with in situ data entry will be an incredibly prominent and powerful form of research in the medical and social sciences in the future. Our goal with this frontend tool is to lower the barrier of entry for this method of research, particularly for non-programmers. In particular, this is a frontend tool for MyExperience project.
 
Angle Mouse: In this project, we are devising a way to make mouse pointing more accurate for people with motor impairments by dynamically adjusting mouse gain based on angular deviation and outlier angles and considerations for wiggle, tremors, direction changes, and pauses.

Diet-aware dining table: This augmented dining table can track what and how much we eat from the tabletop surface. In other words, this table is “aware” of our natural eating behavior. The goal is to provide information about our eating behavior and lead a healthier life. We augmented an ordinary dining table with two layers of RFID and weighing surface. With a rule engine running in it, this table can detect and recognize multiple, concurrent person-object interactions occurring on the table with 80% accuracy. (video)

 
Persuasive interface: It is an interactive, persuasive game built into an ordinary lunch tray to assist parents to improve dietary behaviors of their young children. The persuasive game is played over a smart lunch tray. By eating from the lunch tray, a child can see his/her favorite cartoon character being colored. The smart lunch tray incorporates both the context-awareness (of pervasive computing) and the persuasive media (of persuasive computing), enabling the creation of a smart object that is not only aware of human behavior but can also influence and shape human behaviors through their natural interactions with the object. (video)
 

 
Crowded paradise: Taiwanese night-market is often crowded with lots of people who are looking for delicious foods to eat and small fun items to buy. We think “crowdedness” is one of the main sources of joy in the night-market experience. “Crowded paradise” is an interactive game to connect the level of crowdedness and joyfulness; therefore, provide users with a sense of joyful experience of the nightmarket crowdedness. This game is prototyped using a camera in a box. Visitors can walk by and participate in the game by watching the scene in the box. The scene in the box gradually changes and becomes more colorful and joyful as the number of simultaneously watching participants increase.
