Clinical Kinetics / Crossover Counter

Athlete OS Crossover Counter

The prototype now watches the dribble hand against your hip centerline, detects side-to-side crossover cycles, and counts repetitions while keeping the pose overlay active in selfie mode.

Preparation

Start low, then cross the hand fully through center.

The counter looks for a low dribble pocket, an athletic stance, and a clear left-to-right or right-to-left crossover finish.

Motion brief

Crossover dribble calibration

Start in a low stance and keep your shoulders, hips, knees, and active dribble hand inside the selfie frame.

Counts a rep when the dribble hand crosses body center and finishes on the opposite lane.

Uses mirrored selfie framing so the filter feels natural on iPhone.

Runs in-browser for quick testing without installing a native app.

Safari readiness

01Use iPhone Safari and allow front-camera access when prompted.

02Frame your full body so the counter can compare wrist position against hip center.

03A low stance and a clear hand cross through the torso midline produce the cleanest rep count.

What this prototype measures

Crossover repetition heuristic

The counter uses pose landmarks to infer the dribbling hand, compare it against the hip centerline, and increment when the hand clearly finishes on the opposite side.

Because there is no ball tracking yet, the count is best for form drills and prototype testing rather than official stat capture.
