Decoding Brain Waves

Honda Motor Co. (HMC) has developed a way to read patterns of electric currents on a person's scalp as well as changes in cerebral blood flow when a person thinks about four simple movements - moving the right hand, moving the left hand, running and eating.

Honda succeeded in analyzing such thought patterns, and then relaying them as wireless commands for Asimo, its human-shaped robot.
In a video shown Tuesday at Tokyo headquarters, a person wearing a helmet sat still but thought about moving his right hand - a thought that was picked up by cords attached to his head inside the helmet. After several seconds, Asimo, programmed to respond to brain signals, lifted its right arm.
