About 5 years ago I took my lunch after making a delivery at a place in Whitby that repairs electronics for big manufacturers. They have a small retail outlet out front where they sell some of the repaired/refurbished stuff. They had a PS3 (I think?) with the VR goggles and I dove right in.
There was some racing game running on the system. I got seriously into it, trying different cars and generally having an absolute riot. I was blown away by how real it all looked (even by 5 year ago standards) and the fact that I could turn my head and look at cars beside me, or into the back seat, or at the floor....etc etc.
I was having a great time.
Until I wasn't. I spun the car out on a tight corner and it was at that moment that my brain decided that it had quite enough of my eyes seeing things that my body wasn't actually experiencing. And then the nausea set in. HARD and FAST..
I broke out into a full sweat suddenly. I pulled off the headset and put everything down and slinked out of there very, very slowly, worried I was going to chuck.
I got out to the parking lot and did manage to keep my lunch down but had to literally lay in the shade under my trailer on my back for another 30 minutes until I felt well enough to force myself to get back to work.
I've never done anything VR related since.
