sensory substitution

Sensory substitution is a method that uses one sense to provide information normally gathered by another sense. For example, devices can convert visual data into tactile or auditory signals, allowing someone who is blind to “see” through touch or sound. This process helps the brain interpret information through alternative sensory pathways, enhancing perception and independence. Sensory substitution leverages the brain’s ability to adapt and rewire itself—called neuroplasticity—to compensate for lost or impaired senses, improving quality of life and communication with the environment.
