On-Body Interaction

An interaction paradigm that uses the surface of the user's own body as an input medium, typically through gestures like taps, swipes, or touches on the skin. On-body interaction leverages tactile and proprioceptive feedback from the user's own body, making it potentially efficient for eyes-free use by people with visual impairments. This approach can support both location-independent gestures (performed anywhere on the body) and location-specific gestures (mapped to particular body areas like the palm or wrist), each offering different tradeoffs in efficiency, learnability, and social acceptability.
