Two very cool next generation UIs from MIT:
A new Media Lab system turns LCD displays into giant cameras that provide gestural control of objects on-screen
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.
‘SixthSense’ is a wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information.
