Since 1968 scientists have been creating sensory substitution and augmentation devices. With these devices they try to replace or enhance one sense by using another sense. For example, in tactile–vision, stimulation of the skin driven by input to a camera is used to replace the ordinary sense of vision that uses our eyes. The feelSpace belt aims to give people a magnetic sense of direction using vibrotactile stimulation driven by a digital compass. This talk discusses these developing technologies, mentions psychologists studying the minds and behavior of subjects who use these kind of devices, and analyzes the nature of perceptual experience and sensory interaction. The talk also explores the nature, limits and possibilities of these technologies, how they can be used to help those with sensory impairments, and what they can tell us about perception and perceptual experience in general.
