A camera, a skeleton model and a classifier can detect exercises, gestures, balance, fatigue and unsafe movement patterns without wearable hardware.
Pose detection finds joints. Pose tracking follows them over time. Pose recognition interprets those trajectories as a squat, a fall risk, a dance move, a surgical posture alert or a hands-free command.
The same signal chain applies across health, fitness, games, sports analytics, industrial ergonomics, accessibility and immersive interfaces. The category should name the technical layer, not only one end market.
