A research group at the University of Washington is using brain stimulation to allow people to play simple games. Using a metal coil at the base of the skull, subjects brains are stimulated to allow them to navigate a maze without using any of their senses. Is this the creepiest thing you’ve ever heard?
Players navigate a simple two dimensional maze by using phosphenes, articles that are perceived as little balls of light. The subjects aren’t actually using their eyes to see them. This has great applications in gaming and other media, especially for people who are blind or deaf and could experience sound or sight through brain stimulation.
