Abstract
The Tactile Vision Substitution System converts the visual image from a narrow-angle television camera to a tactual image on a five-jnch square, loo-point display of vibrators placed against the abdomen of the blind person. This arrangement allows for the free use of the hands at the same time that the machine is in use. The possible applications of the system in education include the teaching of certain spatial concepts, e.g., monocular cues, and as an attachment to a microscope to allow for the examination of slides. In employment, the system could be used in those jobs in electronics requiring the use of an oscilloscope (to which it can be attached) or in assembly work involving the microscope, e.g., microcircuitry.
