In the Daily Mail of January 9th there was an interesting piece, "Think and Drive".

It said that you often need to think fast while driving—particularly in a Scalextric-style game.  But now, thanks to ‘mind reading’ technology, the cars speed along slots in the track using the power of thought.

The track, developed by Harvard scientists, is on display at the Consumer Electronics Show in Las Vegas—the global showcase for new tech products.  The cars are controlled via a headset that measures electrical signals in the brain associated with concentration.  The harder you concentrate, the faster the car goes.

The technology, based on conventional medical scanning devices, uses tiny sensors on the scalp to pick up electrical signals generated as brain cells communicate with each other.

Mind-reading technology has huge potential in the toy sector but also gives hope to people who have difficulty operating limbs.  Headsets are already being developed to control wheelchairs and prosthetic hands.
