Waving the Channel

Television viewers will soon be able to change channels with a wave of the hand. A new TV set with a chip-based infrared sensor embedded in its front maps the depth of objects in the room, making it possible to detect hand motions–even when the lights are low. A sharp wave powers up the set; a circular motion flips the channel; an up-and-down motion controls volume. The product is expected to be available in 2010.
