I've got a Quest headset and the thing causes a lot of pressure on my sinuses, making it unwearable for more than about 15 minutes at a time. There are no AR/VR headsets that I'd be willing to strap on to my face for more than about 10 or 15 minutes.
It seems like there are several high technological barriers to surmount though. I don't expect to see that kind of AR for decades.
These are a start.. taking the opposite approach of the Apple device and limiting functionality to what will actually fit in a reasonable form factor right now.
No visual display included, because that would require a clunkier form factor still.
Today's products, even AVP, are way, WAY too big and inconvenient in 50 different little ways to be seriously used for anything.
