Pick a physiotherapy exercise from the University of Melbourne CHESM video library (knee and hip osteoarthritis), open camera + chat, and get live guidance from an AI coach (Gemini Live). No exercise detection — you choose the exercise; the coach guides you. Targeted at elderly people with knee and/or hip OA.
