Amazing wheelchair controlled by mind power

Scientists have developed a wheelchair controlled by the power of thought.

It works by creating a three-dimensional picture of the area around it, with a laser scanner. This is displayed on a screen in front of the user. To steer the chair, the user simply concentrates their thoughts on the part of the display where they want to go. Electrodes in a skullcap then detect the brain activity of the users - and work out their destination.

Volunteers who tested the chair took just 45 minutes to learn how to use it safely and accurately. A commercial version that is even easier to use is currently being developed.

The robotic chair could revolutionise life for those with severe disabilities who are unable to use a conventional joystick.
