Very cool, but that video works by using normal supervised learning (to detect hand gestures) while mine detects the direction your face is pointing in using pose estimation.

Edit: I didn't train the pose estimation model myself, it's taken from a tensorflow.js example: https://github.com/tensorflow/tfjs-models/tree/master/faceme...

How hard would it be to use these tools to detect someone touching their face and throwing a chime to help remind them not to? It could run in the background all day for laptop/webcam users. #covid etc.
