That's cool and all until a couple scenarios.
A) Awesome, I have an IMAX screen on my face. My boss, coworker, spouse, kid, or random person approaches and I want to show them the thing... sure I can take it off and hand it to them so we both swap sweat and face grease but also only one of us can see it at the same time. Screens on a desk or in the hand can be viewed by several people simultaneously.
B) I just got the IMAX screen on my face and everything is comfy. It takes a minute as my head is shaped a little different from the spec the headset was built for, no biggie but takes a minute... and now I have to go pee... rip the headset off and come back in a few minutes to try again. Screens on a desk mean I just get up and leave in an instant any time it's necessary.
A) First, the existence of goggles doesn't eliminate all other screens. Where the "as is" already exists and/or serves a more useful purpose, people will still use screens on desk/lap/phone/tablet/wall/tv/billboard/blimp/watch/etc. This would simply be ANOTHER screen, not the
only screen.
As to sharing a screen issues, you have a telescope in your yard and you are looking at Jupiter. Along comes someone else without a telescope. They want to see Jupiter too. So you may choose to let them have a look.
You have a microscope at your lab desk and are looking at the new samples. You spy something interesting. Co-workers in the lab have a look to see the interesting observation too.
You are using binoculars on the expedition and you spy the prize. The others can’t see it without magnification. So you hand them the binoculars so they can see the prize too.
You find a funny YouTube video on your phone. You laugh. Others around you wonder what is so funny, and you show them on your screen, perhaps passing around your phone in a situation where all eyes can't gather around you.
You flashback to using viewmaster (toy) as a kid. You have some new slide images. You and your friends pass around your viewmaster so they can see it too.
You time travel back to when someone in the neighborhood was the first with a television. Now people they barely know- even complete strangers- want to come over and watch moving pictures.
Yes, all these people can buy/get their own telescope, microscope, binoculars, phone, viewmaster, tv, etc and/or just do without seeing whatever you get to see in yours. But the point is sharing devices to show/see interesting things is nothing new at all. And if you are worried about grease & grime, don’t share.
B) if you have to “rip” anything off of you to be able to take a pee, perhaps that thing is not for you?
If I have a laptop on my lap and need to take a pee, a few simple motions gets the laptop off my lap so I’m free to go pee. No need NOT creating a laptop computer because it will impede people’s ability to go the restroom. People will figure out how to remove it from their lap and go pee.
If I have wired headphones on my head and need to pee, a simple motion removes them so I can go pee.
If a model is wrapped up in an elaborate bit of garb for fashion week and needs to pee, they certainly find a way. I’m yet to see a wet catwalk.
If the Ironman stunt double needs to take a pee, they won’t soon be creating rust in there.
If I’m wearing a helmet for the bike or motorcycle ride and need to pee, a simple motion removes the helmet.
Do skiers generally pee their pants because it’s too hard to deal with their masks?
If I’m a welder, I am not obligated to simply pee my pants because it’s too hard to “rip” that much more sizable mask from my head.
Etc.
Again, it’s fine for people to not like the idea of new technologies such as this one… but neither of these issues comes with some very difficult or undesirable hurdles to use this thing. There’s already plenty of precedent for both issues that don’t overly complicate one’s life and or lead to stinky pants or unfortunate puddles. 😉
And just as we can opt to NOT share existing technology with others, we can simply say “No” to the filthy, grimy, diseased stranger wanting to use our <whatever> now.
