Football Juggling

What is JuggleJs?

JuggleJs counts football juggles from your camera — or from a video file. Put the phone down, keep the ball in frame, and watch the count climb.

Live session

Start / Resume — green control (or a hands-free pose).
Pause — yellow control, or Autopause after idle.
Stop / Reset — red control; clears the count.
Top bar shows timer, count, and menu.

Hands-free poses

Works only while you are not actively counting, so juggling keeps full FPS. Hold the pose about 1 second.

Arms up → Start / Resume

Raise both hands above your shoulders and hold. Same as tapping the green button.

Arms crossed → Stop / Reset

Cross your arms on your chest while paused. Same as tapping the red button.

Settings

Voice — volume for spoken counts and session words (OFF … MAX).
Say every — speak the count every N juggles (session words always speak).
Hands-free — enable pose controls.
Autopause — pause after ~5s without juggles.
Min bounce — how big a bounce must be to count (lower = more sensitive).
Trajectory OFF / Simple / Extended — plot modes; Extended adds color-cycled debug table.
Mirror video — flip the picture left↔right (Live and File). Off by default; counting is unchanged.
From file + Debug step — test with a video; scrub and step frame by frame.

Keep the ball up. Keep the phone down. Break your record — not your screen.
