University of Washington researchers have successfully performed what is claimed to be the first non-invasive human to human brain interface. It allowed one person to control the actions in another, by sending brain signals over the internet. This is certainly not the first brain to brain interface performed, in the past various researchers have been able to demonstrate brain to brain communication between two rats, as well as between a human and a rat, however this is believed to be the first demonstration of human to human interfacing.
In the demonstration, Professor Rao had to look at a computer screen and play a simple video game with his mind, when he was supposed to fire a cannon at a target he had to imagine moving his right hand, without actually moving it, causing a cursor to hit the fire button. These brain signals were then sent to another part of the campus where Professor Stocco, the guinea pig in this experiment, almost instantaneously and involuntarily moved his right index finger to push the space bar on the keyboard that was set in front of him firing the cannon, this movement Stocco compared to that of a nervous tic. It's also worth noting that Stocco was wearing noise cancelling ear-buds and wasn't actually looking at the computer screen.
The demonstration was performed whilst wearing highly specialised equipment under ideal conditions. They also had to obtain and follow a stringent set of international human-subject testing rules to conduct the demonstration.
“It was both exciting and eerie to watch an imagined action from my brain get translated into actual action by another brain,” Rao said. “This was basically a one-way flow of information from my brain to his. The next step is having a more equitable two-way conversation directly between the two brains.”
We won't go into too much detail over the actual technology used for this demonstration, but it certainly looks like another interesting technology is taking baby steps into becoming a usable technology, I mean who can really say no to a bit of mind control ?
