I wear glasses (which I keep inside the helmet) and have mild motion sickness when moving in VR. The faster I move in-game, the worse it gets. Racing games are OK because I don't move inside the car, I suspect having a static dashboard is similar to a virtual nose.

Glasses wearer here. VR makes me nauseous af. And not just during, for hours afterwards. Its not an intense 'I have to vomit' but a queasy feeling that persists. I'm old though, and my kids have zero issues with it.

Glasses wearer here, I still see my nose with the glasses on. VR gives me mild motion sickness but only when moving around in a "smooth" way (Teleporting or walking irl is fine but using regular controller movement makes me want to throw up after ~30 minutes)

Ye! Tbh one of my biggest pet peeves with VRChat is the fact that they shrink your head to avoid it interfering with the player camera, but the result is that you don't have a nose. It's not as obvious with human/humanoid avatars because, like you said, it's normally "edited out" by our brains (though you can probably see it if you want to by crossing your eyes, I know I can see mine); but it ends up being super obvious with furry avatars due to the lack of a snout/muzzle. That said, I've seen a few furry avatar creators starting to add a snout (not sure how they do that, I think they parent a copy of the face onto the head bone), and it's pretty neat. Maybe other avatar creators will follow suit.

I don't think you want a nose for those videos.

So you are saying that 90s is a remarkable improvement?

I would expect a huge difference in the usefulness of a simulated nose, depending on the content. In a roller coaster the movement of your head (rotation) and the movement of the carriage (translation) are separate and clearly defined this way. You control the Rotation while the game controls the translation. I don't know what this villa demo is, but depending on how the movement is controlled, an unintuitive and unnatural system is bound to make almost everyone nauseous.
