At CES (Consumer Electronics Show) in Vegas, Toshiba unveiled a prototype of a television that doesn't require a remote control -- TV watchers simply wave their hands in the air to control the menu, fast-forward movies and turn the volume up or down. Many TV makers are working on "gesture" technology for TVs, and it hasn't been perfected, but Toshiba is among the first to show it off publicly.

In a demo at CES, a woman put her palm out in a "halt" position to select items from a 3-D, spherical menu on the TV screen. She looked like she was swimming the breaststroke when she commanded the TV to zoom in on an image. The TV uses infrared technology to sense a viewer's movements in a particular zone of the room, which a demonstrator referred to as the "couch-potato zone."

So, it's a pantomime version of the Clapper.
