|Hi, Chat’s here! I am a fourth year PhD student at Media Computing Group. I am interested reinterpreting human motions for input to improve accessibility, expressivity, and ergonomics. One track of this is to empower users with hand tremor to use touchscreens with Swabbing input. Since 2011, I directed the second track of my research to mid-air inputs. I also have several works on interactive surfaces. I am interested in research methods and statistics, and even hosted a bookclub in 2012. My lifetime goal is to find a reliable way to make people understand and practice a right mixture of design thinking and scientific method in their everyday life.|
NEWS: If you are interested in topics about midair interaction techniques and devices, drop me an email with your CV. Estimate thesis start: January, 2014.
Recent and On-going Projects
|How We Gesture is a study of how users’ perception and behavior of gestural interaction differ between gesturing to human vs. gesturing to computer. In collaboration with Sukeshini A. Grandhi (previously at Natural Media & Engineering Lab, now at Eastern Connecticut State University). (read more)|
Work-in-progress at CHI 2013
|Indirect Touch is a multitouch system in which users indirectly manipulate objects on the vertical screen by with touches on the horizontal screen. This interaction improves ergonomics of interactions over an extended period by reducing gorilla arm (vertical screen) and stiff neck (horizontal screen). (read more)|

|Swabbing is a touchscreen target selection method designed for users with hand tremor. Instead of touching on the target, the user slides his hand towards a target placed along the edge of the screen.

etc., etc.As a HCI researcher, I am honored to be a reviewer for publications in these venues: CHI (2011–14), UIST (2012, where I blessed with a “Great Reviewer” star, 2013), MobileHCI (2013), GI (2013), SUI (2013), DIS (2012), and APCHI (2012).
