Vision For The Blind

Brainport is a nonsurgical device, intended for the blind and people with poor vision, that consists of an electrode "lollipop" that sits on the tongue and a pair of glasses that contain a small video camera.  The camera sends signals to the device, which "draws" images with mild impulses on the tongue, allowing identification of shape, size and location of objects.
