I am an interaction builder. I am excited about discovering and enabling novel sensing and interaction techniques that challenge the existing ways of using a digital device. My ultimate research mission is to approximate the future by building it today.

I am a 2nd year PhD student in the Human-Computer Interaction Institute in Carnegie Mellon University, working with Prof. Scott Hudson and Prof. Jen Mankoff.

Motion and Context Sensing for Pen Computing (2012) - GI 2013

We explore techniques for a slender and untethered stylus prototype enhanced with a full suite of inertial sensors (three-axis accelerometer, gyroscope, and magnetometer). These sensors enable motion-gesture inputs, as well sensing the context of how the user is holding or using the stylus, even when the pen is not in contact with the tablet screen.

Body-Centric Interaction (2011~2012) - TEI 2012MobileHCI 2012

Body-Centric Browser is a mobile browser that extends tabbed browsing from the small screen to the space on or around the user's body.   
Body Viewer is an image viewer where people can drop an image on their body location and later pick it up.
Pockets: People use their physical pockets to store/access digital objects, e.g., showing and exchanging business cards.   
Body Cobweb is an imaginary cobweb around a person. Close up: shows current contents; Reaching out: grabs contents at the cobweb; Further out: 'sticks' current contents to the cobweb.
Body Workspace is an imaginary workspace on your body (e.g., laps), where you can place, move and organize your work items.   
Body Shortcuts uses body parts to trigger programmable digital actions, e.g., wrist triggers calendar, right knee finds route on a map, abdomen searches restaurants nearby.
Rotating Watch is a watch that shows one of your calendar event at a time. To go schedules, one moves the watch around the body where it switches to next/last event.   
Body Toolbar is toolbar outside the screen, on your body. To select painting tools, go to the right arm; to pick colors go the left arm; etc.
Body Surface people use their dominant hand to touch the device surface and the other to touch the body surface, and the two combined makes various controls.


Calendar Visualization (2010) - AVI 2012

Spalendar == Spatial Calendar, Visualizing people's calendar by showing how they move between different event places. A social network of people can see and access Spalendar from shared public places, and can keep aware of each other's activities and whereabouts.

Visualization & Expressive Rendering (2009) - CAD/Graphics 2011  The Visual Computer 2013

Expressive City explores an expressive rendering approach with various styles integrated in a seamless way. Each view is a combination of photorealistic rendering, non-photorealistic rendering, and line drawing, so as to highlight the information that interests the users and de-emphasize the other that is less important.
