I think part of the disinterest is just that current VR headsets are huge. Who wants to wear that monstrosity on their heads (and then that battery pack hanging off it?) Yuck.
If you can reduce VR headsets to the size of a pair of glasses, like those Meta Wayfairers for example, that size will get people excited.
The Vision system can’t and won’t ever be able to fit in sunglasses like the Ray-Ban Meta. No way, no how. The limitations on a system like that are very obvious. And as many have already pointed out, even if it was glasses, who exactly wants that? What unique and indispensable function would it have that makes the trade offs worth it?
