Movement guide
What forehand form analysis can measure.
Video cannot explain every part of a forehand. It can show repeatable changes in visible joint position and body movement when the camera captures the swing clearly.
Visible mechanics
Measurements, not labels.
Shoulder and trunk movement
Estimated shoulder landmarks help describe how the upper body changes through the clip. Trunk-angle measurements summarize the amount and timing of visible torso movement.
Elbow bend
The angle formed by the shoulder, elbow, and wrist shows how extended or bent the hitting arm appears. KinetiCourt can compare the clip's elbow measurements with its reference values.
Balance and body position
Hip, knee, ankle, and shoulder landmarks provide a frame-by-frame view of stance and body alignment. Missing or obstructed landmarks reduce confidence in the result.
When movement happens
The model also uses normalized frame positions. That lets it describe when a measured peak occurs within the recorded swing rather than relying only on the clip's raw duration.
What video misses
Context still matters.
A pose estimate does not know the player's intent, grip pressure, fatigue, injury history, or whether the shot landed in. It can also mistake a landmark when the racket, clothing, another person, or motion blur blocks the body.
Use the report as one piece of evidence. Pair it with ball outcome, your own feel, and advice from a qualified coach.
