Audio-Tactile Interface

A user interface that combines tactile (touch-based) interaction with auditory feedback to convey information that is otherwise visual. Audio-tactile interfaces are widely used in accessibility to make graphical content such as charts, maps, and diagrams accessible to blind and visually impaired users. The tactile component provides spatial and shape information through physical touch, while the audio component adds detail, labels, and data values through speech, tones, or sonification.
