New tech allows gamers to connect via brain signals
Researchers have developed a new technology that allows multi-player collaboration using only communication through brain signals a step closer to reality.
Researchers from the university of Washington showed that three people can play a Tetris-like game using a brain-to brain interface. This is the first demonstration of two concepts a brain-to-brain network of more than two people, and a person being able to both receive and send information to others using only their brain.
That’s how we came up with the idea of BrainNet: where two people help a third person solve a task,” said corresponding author Rajesh Rao. The game shows a block at the top of the screen and a line that needs to be completed at the bottom.
Two people, the Senders, can see both the block and the line but can’t control the game. The third person, the Receiver, can see only the block but can tell the game whether to rotate the block to successfully complete the line.
Each Sender decides whether the block needs to be rotated and then passes that information from their brain, through the internet, and to the brain of the Receiver.
Then the Receiver processes that information and sends a command to rotate or not rotate the block to the game directly from their brain signals, hopefully completing and clearing the line.
