Toyota technology has brain waves move wheelchair

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.
