The 3D camera tracks your body movements, so you can throw a punch or kick a ball, without having anything in your hand.It will also incorporate face detection and voice recognition, and as well as controlling games, will allow users to flick through films and TV shows on Xbox Live.These latest developments come hot on the heels of last week's news that Sky TV is linking up with Xbox Live this autumn to bring Sky TV and films to the Xbox.
