Audio-tactile interface
Also known as: Audio-tactile system, Talking tactile
An interactive system that combines physical tactile surfaces with electronic audio feedback, providing spoken labels, descriptions, or sonified data when the user touches specific areas of a tactile graphic or map. Audio-tactile interfaces reduce the cognitive load of tactile exploration by supplementing spatial touch information with auditory context, and can be further enhanced with visual augmentation for users with residual vision.
