The BSI-TOYOTA Collaboration Center has succeeded in developing a system which utilizes one of the fastest technologies in the world, controlling a wheelchair using brain waves in as little as 125 milliseconds. The new Toyota system fuses RIKEN’s blind signal separation and space-time-frequency filtering technology to allow brain-wave analysis in as little as 125 ms, as compared to several seconds required by conventional methods. Brain-wave analysis results are displayed on a panel so quickly that drivers do not sense any delay.The system has the capacity to adjust itself to the characteristics of each individual driver, and thereby is able to improve the efficiency with which it senses the driver’s commands.Thus the driver is able to get the system to learn his/her commands (forward/right/left) quickly and efficiently.

The newly developed system allows elderly or handicapped people to interact with the world through signals from their brains, without having to give voice commands. The new system has succeeded in having drivers correctly give commands to their wheelchairs. An accuracy rate of 95% was achieved, one of the highest in the world.
