The SeeHear is a system designed to help the blind. The heart of the system is a single custom chip upon which an image is projected by a lens. The function of the system is to map visual signals from moving objects in the image into auditory signals that can be projected through earphones to a listener. A sensation is evoked similar to that which the listener would experience if the moving objects were emitting sound. We hope that the auditory signals provided by the SeeHear device, in addition to the sound cues already present in the environment, will enable blind people to create a more detailed internal model of their surroundings than that which can be extracted from naturally occuring sound cues alone.
