Interactive experiment / 01
Your hand.
A digital echo.
Move your index finger.
Watch this one follow.
Bend, straighten, explore. All you need is a camera and a little curiosity.

A study of movement, inspired by my printed robotics research. The model follows estimated joint angles; it does not simulate material behaviour or control a physical robot.
Meet the physical prototypesHow it works & camera help
A hand tracker estimates landmarks from your camera. The finger’s three bend angles are measured relative to your palm, smoothed, and applied to the digital model. The model stays anchored so you can concentrate on the joints.
Use even lighting, show your entire hand, and avoid overlapping fingers. Fast motion and hidden joints can make the estimate jump. Try a slight side angle if a bend is hard to read.
If the camera is blocked, allow it in your browser’s site settings and retry. In an embedded browser, open this page in Safari, Chrome, Edge or Firefox. You can use the manual controls at any time.
The tracker and 3D libraries download when needed from jsDelivr and Google’s model hosting. Camera frames are processed locally and are neither stored nor sent to a server. Leaving the page or switching tabs turns the camera off.
Built with MediaPipe Hand Landmarker and Three.js.
