Bin He, professor of biomedical engineering, and his students are working with neuro-engineering and a brain-computer interface, or thinking cap, with 64 electrodes. It makes hands-free mind control of a computer possible. Presently, they're controlling the movements of a pong-like video game. The student puts on the cap, a process that involves making sure each electrode is making contact with the head. The cap is connected to a computer and a monitor. The student concentrates or thinks about moving a hand or other body part. The computer processes the brain waves and translates them into a signal that moves a cursor on a computer screen. He believes this technology will eventually be wireless and will have many practical applications, from video games to simulators. But the most exciting possibility is moving artificial limbs with only the mind. What a powerful thought.
