OrthoTennis

DESCRIPTION OrthoTennis turns live or imported tennis video into a persistent player-case workflow. Record a session or import a selected movie from Photos or Files, review it forward or backward, step frame by frame, jump to candidate events, and inspect synchronized skeleton, ball, phase, motion, stereo and arithmetic measurements. KEY CAPABILITIES • Player-centred cases with retained videos, notes and dated measurements. • Photos, Files and iCloud movie import into private app-managed storage. • Live or imported Apple Vision Skeleton and optional MediaPipe pose recognition. • Tennis-ball tracking, event candidates, Kalman smoothing and motion analysis. • Play, pause, reverse, stop/rewind, frame step, ±5 seconds, timeline seek and 0.25×–2× review. • Complete measurement reports with TXT, CSV and JSON export. • One-camera technique proxies and calibrated stereo evidence when valid geometry is available. • Reliable conventional rear-camera baseline with optional supported calibrated built-in stereo. • Encrypted derived-observation broadcasting to the Vision products. OrthoTennis is a sports-performance documentation and coaching-support tool. It does not provide medical diagnosis, injury-risk prediction, treatment recommendations, return-to-play clearance, official line calling, or laboratory force/kinetic measurements. Automatic pose, ball, event, phase and triangulation outputs must be reviewed with the source video and capture-quality evidence.
