So a team of neuroscientists sent a message from the brain of one person in India, to the brains of three people in France, using brainwave-reading equipment and the Internet. Yes, really.
The process is slow and cumbersome. It also doesn’t make use of any bleeding-edge technology. Instead, it puts together neurorobotics software and hardware that have been developed by several labs in recent years. We’re not predicting that this will have practical applications, or society-changing implications, any time soon. Still, it’s pretty amusing that somebody did this, and we’re here to give you the step-by-step instructions on how.
- The emitter—we’re using the vocab and italics from the original paper because they are awesome—wears an EEG cap on her scalp that records the electrical activity in her brain. The cap communicates wirelessly with a laptop that shows, on its screen, a white circle on a black background.
- The emitter translates the message she wants to send into an obscure five-bit binary system called Bacon’s cipher, which is more compact than the binary code that computers use.
