Well I posted my interpretation of how to handle UI in a WebXR world with devices which also have hand & eye tracking. Arrangements have also already been made for slightly different version for the release vid here.
It was a weird moment when I was trying to solve the problem of how to show the UI-Portal when it was being blocked by the user stand in. When the obvious solution of changing to being the stand in came to me, I was hesitant thinking ‘Jumping the camera all over the place is going to confuse the watcher’.
Duh, TV & movies have been doing that forever. Enjoy!
