Interactive Smart Computers
Takeo Igarashi


Current user interfaces are not very smart in that computers dumbly do what the user explicitly commands it to do via buttons or menus. As computers become more capable and applications become complicated, more smart user interfaces are desired.

We are exploring possible smart user interfaces in the domain of pen-based computing and interactive 2D/3D graphics. The idea is to allow the user to intuitively express his/her intention in the form of freeform strokes, and have the computer take appropriate actions without explicit commands.

This talk consists of many live demonstrations to illustrate the idea of interactive smart interfaces. I plan to show 2D geometric drawing program, electronic whiteboard system, sketch-based 3D modeling, automatic zooming, clothing manipulation interfaces, two-handed manipulation of drawings,and other interesting systems.


Takeo Igarashi is an Associate Professor in the Computer Science Department at the University of Tokyo. He was a post doctoral Research Associate at the Brown University Computer Graphics Group from June 2000 - Feb 2002. He received the Ph.D from the Department of Information Engineering, the University of Tokyo in 2000. He also worked at Xerox PARC, Microsoft Research, and Carnegie Mellon Universety as a student intern. His research interest is in user interfaces in general and his current focus is on interaction techniques for 2D/3D graphics. He received the SIGGRAPH Significant New Researcher Award in 2006.
