Hitachi Gesture Remote

Among the many interesting concept areas in Hitachi's booth was the gestural remote control. By waving your hands in various simple gestures, you can control the volume, change the channel, dim the lights, and other tasks, and the onscreen user interface is simple and attractive. The system uses a 3D camera and infrared beams to sense your gestures. It felt a bit awkward at first, but I believe I could get the hang of it eventually.
