"Brain-computer interfaces are quickly becoming more advanced and accessible, and some of the ways they're being used are truly mind-boggling.
Why toil with the pressing of buttons or tilting of joysticks when controlling something can be as simple as thinking about it? This kind of technology may sound like the stuff of science fiction, but in reality, it’s actually been around for decades. The development of electroencephalography (EEG) technology can be traced back to the 1920′s, but it wasn’t until recently that we figured out a way to use neurofeedback to control electronic devices. Nowadays, we can use brain-computer interfaces (BCI’s) to control everything from prosthetic limbs, to robotic arms, cars, and even things as simple as your computer’s cursor."
