Hitachi Arm & Hands Built-in Sensor TV

Those who often struggle to find a TV remote may be pleased to know some makers are working on new ways to control the set. At the Consumer Electronics Show in Las Vegas in January, Hitachi (HIT) showed off a new set letting users wave their hands in front of the TV to turn it on. It has a built-in sensor that creates a 3D map of what's in front of it to use hands and arms to move through menu functions.
