Mind-control games may be the coming thing: Mattel plans to demonstrate a Mind Flex game (also due this fall), which uses brain-wave activity to move a ball through a tabletop obstacle course, at the Consumer Electronics Show in Las Vegas on Thursday.

In the Force Trainer, a wireless headset reads your brain activity, in a simplified version of EEG medical tests, and the circuitry translates it to physical action. If you focus well enough, the training sphere, which looks like a ping-pong ball, will rise in the tower.

A state of deep concentration is needed to achieve a Force-full effect. "When you concentrate, it activates the training remote," says Frank Adler of toymaker Uncle Milton Industries, which is creating the Trainer. "There is a flow of air that will move the (ball). You can actually feel like you are in a zone."
