Here’s today’s fill of futurology.
Researches achieved brain-to-brain communication where one person was able to control the movements of another person’s hand by simply thinking about it.
The study — published yesterday by The University of Washington — involved three pairs of participants working together to play a computer game. Each duo was comprised of a “sender” and a corresponding “receiver,” who sat in a room a half mile away.
In the experiment, each sender was placed in front of a computer game that involved firing a cannon and intercepting rockets to protect a city. The senders, however, were unable to physically interact with the game. They could only defend the city by thinking about moving their hands to fire the cannons and intercept the rockets. Meanwhile, the corresponding receivers sat in a distant, dark room with no ability to see the game and their right hands positioned over touchpads that controlled the game.
The senders were hooked to EEG machines that read brain activity, and their partners wore caps equipped with technology to stimulate the part of the brain that controls hand movements. When the senders thought about moving their hands to shoot the cannon, their partners’ brains received the message to do so via signals sent from their partners’ brains to theirs over the Internet.
Accuracy among the pairs varied from 25 to 83 percent, but the researchers found that most misses were caused by senders failing to accurately execute the “fire” command, not by failure on the receivers’ ends.
