Mind pong
Electrical engineering students Chuck Moyes and Mengxiang Jiang play Pong with their brainwaves in the video below.
Writes Engadget: “Their experiment links a baseball cap full of EEG-scanning electrodes to a computer, letting the cap wearer control a paddle using Alpha or Mu waves. Depending on the waves you use, you can move the paddle either by changing your concentration level or by thinking about moving your feet. You won’t rack up a high score while napping (or with a teammate narrating over your shoulder), but with a budget under $75, it’s hard to find fault.”
