Two Cornell University electrical engineering students, Chuck Moyes and Mengxiang Jiang created a brain-controlled version of the classing Pong game. The experiment connects an EEG brain-computer interface to a microcontroller, letting the player control a paddle using Alpha or Mu waves. The user can move the paddle either by changing his concentration level or by thinking about moving his feet. Unbelievable? Check the video below and believe your own eyes.
