Researchers at Carnegie Mellon University and Microsoft’s Redmond research lab have developed a working prototype of a system called Skinput that effectively turns your body surface into both screen and input device.

Skinput makes use of a microchip-sized pico projector embedded in an armband to beam an image onto a user’s forearm or hand. When the user taps a menu item or other control icon on the skin, an acoustic detector also in the armband analyzes the ultralow-frequency sound to determine which region of the display has been activated.

The technology behind Skinput is described in this paper the group will present in April at the Computer-Human Interaction conference in Atlanta.
