Microsoft’s Project Natal, a bar that sits above or below your TV, lets you control games just by moving around, using a camera, sensors and a microphone.

It lets you move through menus by swiping your hands back and forth. The camera allows for facial and voice recognition and will recognize your face and sign you in automatically.

It also tracks your full body movement in 3-D, while responding to commands, directions, and even a shift of emotion in your voice.
