Before you start
π Your camera stays on this device. Pose tracking runs
entirely in this page on your own machine β video is never uploaded,
recorded, or stored anywhere. Nothing leaves your browser.
Stand back so your whole body is in frame (head to feet,
roughly 2β3 m), in decent light. Then do jumping jacks β the wizard
does them with you. 100 real ones is a real workout (~2β3 minutes):
rest whenever you like, and stop if anything hurts. The counter only
moves on complete reps.
Camera: off β permission is only asked when you click START CAMERA.
