Researchers in Japan, backed by automaker Toyota, have demonstrated a thought driven wheelchair that is said to have achieved as much as 95% accuracy rates. According to this CBC article "The system measures electrical activity in the brain through five electroencephalography (EEG) electrodes placed above the areas of the brain that handle motor movement. The sensors interpret the signals they pick up and translate them into motion." The technology, still in the developmental stage, is hoped to be useful for rehabilitation and for support of people who use the vehicles. Japan has an aging population and as the result an active robotics industry, with much support and encouragement from the government which is facing a demographic shift.
