Selection With Eyes - Quest Pro (and future headsets)?

Hi All, thought I'd ask in here about whether there is any work going on for a user interface for people with limited or no use of their arms because of a thread in the Talk VR section of the forums?

If we think back to the Gear VR, selection could be made by holding your gaze on buttons.  

The Apple Vision Pro does use this for some things, you don't always have to tap your finger and thumb and going forward, all headsets will have eye tracking soon enough.

Interested to hear what people think.  Thanks.
