Computing with a wave of the hand (w/ Video)

(PhysOrg.com) -- The iPhone`s familiar touch screen display uses capacitive sensing, where the proximity of a finger disrupts the electrical connection between sensors in the screen. A competing approach, which uses embedded optical sensors to track the movement of the user`s fingers, is just now coming to market. But researchers at MIT`s Media Lab have already figured out how to use such sensors to turn displays into giant lensless cameras. On Dec. 19 at Siggraph Asia -- a recent spinoff of Siggraph, the premier graphics research conference -- the MIT team is presenting the first application of its work, a display that lets users manipulate on-screen images using hand gestures.
