Another report of motion sickness with the Oculus Rift
Among an otherwise glowing hands-on experience report with the Oculus Rift, another mention of motion sickness:
Did you feel nauseous/sick or get a headache during or after use? No headache at all, but I have to say that after about 10 minutes, I felt really sick in my stomach. I had eaten a rather heavy meal right before my gaming session and that made it probably much worse, but it was unpleasant. I usually don't have big problems with reading in a car or motion sickness in gaming, so this was very surprising for me. To be fair, I was standing up and putting the thing to the test, making fast turns, jumping around, standing really close to ledges, looking up and down repeatedly, using the analogue stick in different ways – so this has probably worsened the motion sickness I experienced. Also, Nate and Palmer said that they are aware of the issue and can adjust for it. For example, positional tracking should help a lot to alleviate the motion sickness problems. Also, Nate pointed out that swaying while standing as well as using the right analogue stick too much worses the motion sickness. I did both probably too much.
The nauseous feeling got worse, but sitting down felt much better. It was a little less immersive that way, but still great. It worked surprisingly well even when sitting down, which is a huge plus if you ask me: If you want to sit down in your living room and relax, you can – and still get an immersive experience. The nauseous feeling stopped about 10 minutes after playing, but I felt a little woozy for about 2 hours.
