Apple Shifts Focus from Vision Pro to Smart Glasses

There has never been any significant demand for headwear displays.
I'm not sure what degree of sophistication they have to hit for people to catch on, my hunch is it needs to use transparent lenses with at least 90 degrees FOV of display, full 6DOF tracking, eye tracking and hand tracking. Vision Pro's performance capabilities are overkill, but something with it's user experience in a pair of lightweight glasses,even if it's mostly floating virtual windows and environmental overlays with simple graphics, would be self evidently useful to anyone who would try them for a few minutes.
None of the products released thus far have hit the mark, though.
That's not to say that some changes etiquette won't develop, but think about it this way: no one asks someone else to put their phone away in private residences during conversations because it has a camera on it, but they might because they want the other person's full attention.
