Technology for the impaired is always widely appreciated, regardless of its eventual effectiveness. The BrainPort vision device has been developed specifically for people with visual impairments. The basic premise of this device is in creating tactile images on the tongue, and thus enabling the patient to ‘feel’ the images. The input for this device comes from visual information gathered by a user-adjustable head-mounted camera. The processed information is sent to the BrainPort base unit, which converts it into electrical patterns projected on to the tongue. The resulting image is perceived as stimulation, wherein white pixels are strong, black is no stimulation and gray is medium.
