Wiimote Turns TV into Touchless MS Surface
RemyBR writes "User interface project allows you to control objects on a display using gestures, working like Microsoft's Surface but without touching the screen at all. Inspired by Johnny Chung Lee's work, the system requires you to wear Minority Report-style gloves equipped with infrared emitters on your fingertips. A Wiimote on top of the display keeps track of these IR LEDs, while the software can read the motion down to two-finger pinching gestures for image zooming."
Would it be possible to shine IR light through the edge of a plexiglass surface, and then when the user touches the surface it would cause the IR to scatter at that point creating a point source for the Wiimote to track?
