I wrote down a very basic spec on how eye and face tracking can be implemented: https://cabanier.github.io/webxr-face-tracking-1/ Here's the [README](https://github.com/cabanier/webxr-face-tracking-1). Comments welcome :-)

@dmarcos do you want to discuss this at the face to face next week? (March 25-26)

@toji updated with [a831680538590bb9ddd87b02a31584f7063ad948](https://github.com/cabanier/webxr-body-tracking/commit/a831680538590bb9ddd87b02a31584f7063ad948)
the positions of the hand and the controller would be different. It's not just that you get the controller inputs.
yes, this is why it only works with Quest Pro controllers. They are self tracked so they don't need IR emitters and HMD camera tracking.
