The Xbox Kinect project is an embodiment of a new generation of user interface. Broadly, the history of user interface for computers is: green screen and cursor, mouse and windows, touch and multitouch, and now “no touch” or “action at a distance”. Kinect has developed “no touch” interaction in the gaming context and brought Natural User Interface technology to consumer scale. Now the research challenge is to see how NUI technology can be developed in more general settings and with a more versatile design methodology.
