We'll probably have some form of GVS in the future in order to mitigate the more extreme cases of disorientation from the acceleration/vestibular mismatch, but if seeing any sort of large scale objects moving relative to you (large windows moving on a big screen TV) is enough to make you feel queasy then you might be in the small minority that will never be able to cope well.
It doesn't happen generally with 2D or 3D movies. Although the Doom movie was notable for making me a bit queasy near the end with the first person camera gimmick that they did. However, I think that had more to do with the low framerate of movies combined with the first person view. I should make a 60 FPS interpolated encode of that scene sometime to test it out. I'm curious now whether that would affect that.
I also noticed that 2D movies viewed without a background on a VR device can make me feel a bit queasy if large sudden camera movements are made (shaky cam, for instance) but it's generally not too bad. However, the same camera movements with the 3D version of a movie would induce significantly more discomfort, though generally not enough to potentially induce vomiting. At least with what I tried. I wouldn't be surprised if there was something that might though. I don't know if there's going to be a 3D version of Hardcore Henry, but seeing some video reviews of it makes me think that might possibly do it.
Most of that disappears with a rendered environment (cinema, room, drive-in) but not completely in the more extreme cases.
One thing that will immediately start the ramp up towards vomiting, however, is when I've viewed 180 or 360 degree VR video clips where the cameraman is moving the camera around like a traditional cinematographer. I can't take more than a few seconds of that before the nausea starts to rapidly build. I suspect if I kept viewing it for a minute or maybe less, that I'd be disgorging the contents of my stomach in quick order.
The thought of being in a VR simulation where I'm small enough to fit in someone's palm and they are moving me around just makes me queasy in the extreme.
Real life situations that cause people to vomit (roller coasters, spinning teacup rides, etc.) don't make me queasy, however. But there is one real life analogy that does. If I'm riding in the backseat of a car sitting sideways and looking out a side window AND the car is subject to a lot of stop and go or very rough and frequent gear shifts. It's pretty specific, but mirrors the nausea that I've felt in VR.
