TV's could soon be controlled by a wave of the hand using new technology developed at a UK university. Researchers have created the Matchpoint system that makes it possible to interact with screens simply by using body movements or waving objects. It lets users change the channel, adjust the volume or access their TV guide simply by moving their hand, or even an everyday object like a cup of tea. TV's could soon be controlled by Minority Report style gestures using new technology developed at a university in the UK. Requiring only a simple webcam, Matchpoint works by displaying moving targets that orbit a small circular'widget' in the corner of the screen.
