Fitted barf bag?
As a bit of releif from all the porn experts:
I led a team developing a high-performance headset like Oculus some years ago. Our test bed was a copy of Descent, with very high-res graphics and really fast GPU processing. We found that 1 user out of 3 couldn't take the "roll-over" at the start of Descent, where the user dives down a mine shaft.
We kept a bucket by the test setup!
