The future is here again. Scientists in New York successfully tested a helmet that picks up brainwaves, enabling people to move a computer cursor with their thoughts alone. Something like that was accomplished a few years ago, but only through the unappetizing expedient of implanting electrodes in your brain.

Controling machines with your mind is not just really cool, it's the road ahead for disabled people to live an independent life. More sophisticated sensors will eventually make it possible to turn home appliances on and off at will or surf the 'Net.

Beyond that, one can envision a mentally operated exo-skeleton to give the paralyzed near-normal mobility. Or think of actuators controlled by brainwaves rather than nerve impulses, implanted in all the inoperable areas of the body, giving an accident victim the ability to walk again.
