Vision Substitution by Tactile Image Projection


WE describe here a vision substitution system which is being developed as a practical aid for the blind and as a means of studying the processing of afferent information in the central nervous system. The theoretical neurophysiological basis1 and the physical concept of the instrumentation2 have been discussed previously, and results obtained with preliminary models have been briefly reported3. A detailed description of the apparatus will appear elsewhere (manuscript in preparation).
