How it works
Face mesh
A neural network places 478 points on each face, including the irises. From them the tool works out where you're facing and looking, and reads 52 facial movements such as smiling, blinking and raised eyebrows.
Hands & gestures
21 points per hand, for up to two hands. The tool counts raised fingers and recognises gestures such as thumbs up, victory and open palm.
Eye colour & body
Eye colour is estimated from the pixels inside each iris, so lighting changes the result. A third model tracks 33 points on the body.
