Parents who implore their children to put down the controller to that video game may soon get their wish.
Many video game companies are now developing controllers that do not require the use of hands.
The new little platform made by Nintendo will let your feet do the playing. It's called a balance-board, and it is loads of fun if you're playing a skiing game.
One company is developing a motion-capture camera that will allow your gestures to control game play.
"We have a camera that actually tracks you in 3D space," Rich Flier said. "It knows where you are, so at all times it can tell what you're doing. Whether you're just moving your fingers around and what that means. all the way through the large big gestures like you're seeing right over our shoulder here -- a boxing game."
Perhaps the most impressive feature of all -- one company developed a little headset that can monitor your brain waves.
One gamer managed to make a cube on screen disappear -- just by thinking about it.
