- Calibration accounts for room, chair, clothing, and camera angle; the site says frames are discarded after on-device analysis.
Field notes
Setup calls for a webcam or iPhone positioned about a metre away, low enough to keep both legs in frame; the page notes that a laptop's built-in camera sits too high. Calibration covers five named poses and the app offers a delay setting to avoid nudging on brief shifts. The page also qualifies its health discussion: it says the research is thin and states that SitSquare is not a medical device or medical advice.
