Tactile Substitution for Vision

Sensory Substitution ( SenSub ) is an approach that allows perceiving environmental information that is normally received via one sense (e.g., vision) via another sense (e.g., touch or audition). A typical SenSub system includes three major components: (a) a sensor that senses information typically received by the substituted modality (e.g., visual), (b) a coupling system that can process the sensor’s output and drive the actuator, and (c) an actuator that activates receptors of the substituting modality.
