steering with your brain

TOKYO (AP) — Toyota Motor Corp. says it has developed a way of steering a wheelchair by just detecting brain waves, without the person having to move a muscle or shout a command.

Toyota's system, developed in a collaboration with researchers in Japan, is among the fastest in the world in analyzing brain waves, it said in a release Monday.

Past systems required several seconds to read brain waves, but the new technology requires only 125 milliseconds — or 125 thousandths of a second.

The person in the wheelchair wears a cap that can read brain signals, which are relayed to a brain scan electroencephalograph, or EEG, on the electrically powered wheelchair, and then analyzed in a computer program.

Research into mobility is part of Toyota's larger strategy to go beyond automobiles in helping people get around in new ways.

The new system allows the person on the wheelchair to turn left or right and go forward, almost instantly, according to researchers.
