Light Glove

Merely strap the wireless device to the underside of your wrists and allow the optical sensors to detect your finger's typing movements for "air typing" or as if you're using a "virtual keyboard". With built in pointers on each side, your typing and mouse functions converge into an ergonomic, wireless and wearable device. http://www.lightglove.com/
