Mind-Controlled Wheelchair Unveiled

Japan's Toyota Motor said on Monday it had invented a way to allow a person to steer an electric wheelchair through simple thought, using a helmet-like device that measures their brain waves.

The cutting-edge Brain Machine Interface (BMI) technology uses electrodes attached to the scalp to measure localised brain activity when a user concentrates on certain physical movements.


The signals are displayed on a panel in almost real time and translated into instructions to steer the motorised wheelchair, the researchers said.


"Such systems allow elderly and handicapped people to interact with the world through signals from their brains without having to give voice commands," Toyota said in a statement.
