Who hasn’t tried to send a message telepathically? Whether it was in grade 5 and you were trying to tell your best friend across the room a secret message, whether it was just this morning trying to tell the slow driver in front of you to go, or whether it was your grandfather clearly trying to give you a non-verbal message which you just didn’t understand….but you wished you could understand – well, someone has actually succeeded in making it happen!
In 2014, scientists and researchers in Barcelona achieved the first non-invasive human brain-to-brain communication. For details see here:
This type of technology is called Brain Computer Interfaces, or BCI for short, and has progressed greatly in less than a century, and includes the first brain implant only 20 years ago. Although the idea that a human brain can control a robot across the galaxy seems like something taken directly from Dr Who, amputees have been using their minds to control their own prosthetic limbs for a few years now. This includes Leslie Baugh, who lost both arms in an electrical accident 40 years ago and became the first shoulder-level amputee to wear and simultaneously control a pair of mind-controlled prosthetic arms.
Never left behind in the tech scene, the gaming world has already begun testing BCI gaming and virtual reality systems for fun (https://www.hindawi.com/journals/cin/2016/3861425/) and also for physical and mental rehabilitation (http://factor-tech.com/feature/brain-computer-interfaces-the-video-game-controllers-of-the-future/).
However, the need for a communication device to communicate with non-verbal humans has been discussed for a while now (https://www.uwo.ca/fhs/csd/ebp/reviews/2009-10/Deagle.pdf), and even though limited messages have been sent as far as from India to France, John Trimper, an Emory University doctoral candidate in psychology, points out that, “It is, however, not too soon to start considering the ethical implications of future developments, such as the ability to implant thoughts in other people or control their behavior (prisoners, for example) using devices designed for those purposes. “The technology is outpacing the ethical discourse at this time,” Emory’s Trimper says, “and that’s where things get dicey.”” Read more: http://www.smithsonianmag.com/innovation/why-brain-brain-communication-no-longer-unthinkable-180954948/#VXxELMtlXeiRkJoH.99
