Vibro-audio Interface
Also known as: VAI
An assistive technology that combines vibration patterns and audio feedback to convey spatial and graphical information through touchscreen devices. Originally developed to make maps and diagrams accessible to people who are blind, VAIs can render shapes, routes, and directional information through haptic vibrations synchronized with audio cues. For autonomous vehicles, VAIs offer a way to communicate driving routes, nearby landmarks, and real-time navigation updates to passengers with visual impairments using their existing smartphones.
