EEG Brainwave-Controlled Pong Game

We also implemented an alternative control scheme using mu suppression which we tried measuring using C3, C4, and Cz. This worked by having the user imagine (or actually move) their hands or feet to control the paddle movement. The other thing was that we actually used back of the head (mastoid) and right ear lobe instead of G.

The last thing I'd like to mention is that frontal alpha measurement is all over the research literature -- commercial products exist that use headbands to measure alpha activity. We noticed increases in alpha wave spectral power when the subject was relaxing or meditating -- precisely when the subject would least likely be scrunching their forehead. This was noticed even in neurofeedback applications when the subjects were not playing the game.
