Hand gesture camera with real-time effects
Show a hand sign to your camera and watch it come alive. Hand Sign Camera recognizes 16 gestures, from a simple thumbs up to two-hand heart hands, and gives every one its own visual effect.
How it works
Everything happens live in the browser tab. No account, no download, no upload.
Allow the camera
Open the camera page and allow access. The hand tracking model loads once and is cached.
Make a hand sign
21 points on each hand are tracked and matched against the shape of every gesture, many times a second.
Watch the effect
Each gesture triggers its own effect, drawn on top of your video. Record a clip to keep it.
16 hand gestures, 16 effects
Every card leads to a step-by-step guide: how to make the sign, what it means, and how the camera tells it apart from similar ones.

Two hands at once
Each hand gets its own gesture and effect, and heart hands or a double palm join both hands into one.
Private by design
Recognition runs on your device. Your video is never uploaded. Read how.
Works offline
After the first visit the app and model are cached, so it keeps working without a connection.
Record clips
Capture the camera view with the effects as a video file, saved straight to your device.
Code view on desktop
On a computer, the camera sits in a code editor layout with the live source, landmarks and tracker log.
Demo without a camera
No webcam? Watch the demo: animated hands run through the same recognizer and effects.
