> My experience is that the better the 3D device, the worse the nausea is. What I think is going on there is that you are successfully fooling the bodies visual inputs, but these are being cross referenced against your bodies Vestibular system in the inner ear.
This is true. But some people, at least, can get used to it to a significant degree.
My first session with Playstation VR, major vestibular disruption and I tapped out after 30 mins or so.
A few sessions later, I was doing hours at a time with no problems at all.
To this day, pulling extreme maneuvres in a fighter jet in VR induces a wave of unpleasant sensations - but then so would doing it for real!
For those who can never find their 'VR legs'...yes, value very much limited to no-lateral-movement experiences.
