Unhealthy postures have become increasingly prevalent, affecting health and productivity, yet existing posture-correction devices rely on intrusive external reminders. We present Tuotle, a desktop robot that leverages cognitive dissonance by adopting a “bad posture,” prompting users to correct it and, in turn, reflect on their own posture. A pilot user study shows it has comparable posture-correction effectiveness to traditional devices, while showing significantly better user experience and long-term adoption intentions. Our work demonstrates that psychological mechanisms can be activated through human-robot interactions, opening new directions for technologies grounded in human psychology.
