Few video games are more basic than Pong, but Charles Moyes and Mengxiang Jiang’s version is incredibly complex.The two Cornell University students built a custom
electroencephalography (EEG) device so they could control the game’s onscreen paddle with their minds.The alpha waves that EEG machines read are faint electrical signals; Moyes and Jiang ran the EEG readings through an amplification circuit to filter and boost the signals.The amplified readings are then
digitized and sent over USB to a computer running the game.
Spiking alpha waves produced during relaxation move a player’s paddle up, and smaller waves indicating concentration move it down.The size of the waves determines how much the paddle moves.
