Thought control of devices takes another step forward with this wheelchair arm that is controlled by thought alone, as reported at Discovery.com. University of South Florida researchers mounted a robotic arm on a wheelchair and a helmet on the user's head. The helmet includes electromagnetic sensors that respond to excitations in the brain resulting from the user thinking about moving the arm and acts on its interpretations. Pretty cool. Previous experiments have yielded thought controlled pointing devices for computers (link not available at the moment).
