Not entirely sure if this helps with motion sickness or makes it worse. When I first started playing VR I was too exhausted to keep standing and used a rotating chair for a bit, which pretty much instantly made me sick.
That was basically the only time I got sick, I don’t have an issue with loopings, flying, etc. Could just be that I wasn’t as used to it yet though.
It definitely looks like an interesting idea, but yeah it could be really bad. Perhaps it does work though, in that case it‘s mix of sitting and physically turning. I guess we’ll see
