Star Trek fictional VISOR worn by Geordi LaForge might become reality soon, researchers say. The Star Trek Visor is a device used by the blind to artificially provide them with a sense of sight. The device scans the electromagnetic spectrum, creating visual input, and transmits it into the brain of the wearer via the optic nerves.

“Researchers have proposed a brain impant for the blind, whereby visual signals could be wirelessly beamed directly into the brain. The idea behind this is that a blind person would wear a special pair of glasses that could record video images using two digital video cameras. This video would then be wirelessly beamed into an implant that would translate that video into electrical signals to stimulate a specific area of the brain. This area of the brain is called the lateral geniculate nucleus (LGN) and is a part of the brain’s processing system for sight. By electrically stimulating this area of the brain, it can give a blind person the impression that they are actually seeing something visually. Scientists have already electrically stimulated this area of the brain in primates and found it had induced sight perception.” via [Brain Stimulant]
