Gesture Replay Kit

A motion lab without the footage

Replay the gesture.
Not the person.

Capture pose and hand landmarks, reproduce a missed move, then compare threshold rules frame by frame—all locally, with no video retained.

  • No account
  • JSON stays local

Movements become test fixtures—not recordings.
Landmarks are not anonymous. Get consent, collect only what the game needs, and delete fixtures when the test is done. Read the privacy note

Local fixture workbench

Current fixtureNo trace loaded

Bridge accepts local gesture-replay:frame window messages from your detector.

Bring a landmark trace

Drop a JSON fixture here or load the anonymous example. Raw video is neither requested nor supported.

Typed ESM + CommonJS. Zero runtime dependencies. The format is open and versioned.

  1. 1

    Record

    Feed timestamped pose or hand arrays into LandmarkRecorder. Video is not a valid input.

  2. 2

    Reproduce

    Use frameAt and ReplayClock for deterministic time and speed.

  3. 3

    Compare

    Evaluate threshold rules with hold time and inspect every disagreement interval.
