Mirroring

The tendency of people in social interaction to unconsciously or deliberately copy each other's postures, gestures, expressions, and speech patterns, which psychology research identifies as a non-verbal marker of rapport and affiliation (the "chameleon effect"). In human-robot interaction and accessibility research, mirroring emerges as a key mechanism by which users build a sense of connection with a robot: participants bow back when a robot bows, cheer when it celebrates, or imitate dance moves. Designers can exploit mirroring by embedding simple, recognisable gestures (nods, bows, high-fives) that invite imitative reciprocity, which is particularly valuable for users with intellectual disabilities for whom non-verbal channels may carry more weight than speech.
