Visual Input Devices

Visual input devices consist of low vision devices, such as magnifiers that enlarge print for people with low vision, Closed Circuit Televisions (CCTV), which enlarge the image, and optical character recognition devices (OCR) that allow printed information to be  converted to digital information. Once converted to a digital format, information can access information through output devices in the client’s preferred format (visual, speech or tactile).
