For those paralyzed from the neck down, controlling a wheelchair even with a joystick is impossible. Researchers at Japan's Miyazaki University have created a wheelchair that solves that problem with electrodes affixed to the face. Certain motions will cause the wheelchair to move, stop, and turn--and it can all be done above the neck. An array of electrodes are attached to the face, and a few distinct motions control it. Clenching the jaw starts it moving forward, and a hard wink on either eye--hard enough to tense the cheek muscle, which triggers the electrode--indicates a turn. A second clenched jaw stops the chair.
