 The BrainPort vision device is a visual prosthetic designed for those who are blind. 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. With training users perceive shape, size, location and motion of objects in their environment. It is a functional, non-surgical device developed to demonstrate as an aid to the visually impaired. The BrainPort vision device is the only new technology likely available in the near term to address safety and mobility issues resulting from blindness.
