On the left, drag to turn the piece, pinch to zoom, or place it in AR. On the right, see motion parallax and changing highlights together as you move your head.
Camera starts only when you choose. Video and landmarks stay on this device; nothing is recorded or uploaded.
Start facing the screen in even light. Hold still briefly to set the center; use “Center here” after repositioning the phone. Move sideways rather than only turning your face. On iPhone, Safari is the recommended place to try the camera and AR link.
Loading the original brooch…
Drag with one finger to rotate; use two fingers to zoom. On desktop, drag and use the scroll wheel. Open AR in iPhone Safari to move, rotate and resize the piece in your room.
Move your head to see around the jewel and watch its reflections change at the same time. The window and lights stay fixed; one tracked camera creates both effects.
Use Start head tracking above, Play demo motion, or the manual viewpoint slider. No camera is needed for demo motion.

MediaPipe locates eye landmarks using the front camera. Their midpoint and separation estimate relative head movement after centering. This is camera-based perspective, not TrueDepth, gaze tracking, or a measurement of viewing distance in meters. Turning your head can affect the distance estimate.
Moodwatch’s face-detection approach informed the choice of MediaPipe. This page uses a separate, local landmark tracker for position only.
