For those who are blind, the non-surgical BrainPort vision device is an investigational assistive device for orientation, mobility, object identification and spot reading. It enables perception of visual information using the tongue and camera system as a paired substitute for the eye. Visual information is collected from a video camera and translated into gentle electrical stimulation patterns on the surface of the tongue. Users describe it as pictures drawn on their tongue with champagne bubbles. With training users may perceive shape, size, location and motion of objects in their environment. The BrainPort vision device is intended to augment rather than replace other assistive technology such as the white cane or guide dog.
Very impressive.
