Researchers from the University of Washington have developed a method of playing games with just a persons mind. In their testing, 3 participants were connected using a brain-to-brain interface to play a Tetris type game. The participants were put in different rooms and couldn’t see, hear, or speak to each other.
Two people, the Senders can see the game, but can’t control the game. The third person, the Receiver is the only one that can tell the game to rotate the block or not. Besides seeing the game, the senders screens showed the word “Yes” on one side and “No” on the other side. Beneath the “Yes” option, an LED flashed 17 times per second. Beneath the “No” option, an LED flashed 15 times per second.
Once the Senders make a decision, they send it to the Receiver’s brain by concentrating on the corresponding light. Read the full article to learn more.
