"Simulator sickness is very common," said David Whittinghill, an assistant professor in Purdue University's Department of Computer Graphics Technology. "The problem is your perceptual system does not like it when the motion of your body and your visual system are out of synch. So if you see motion in your field of view you expect to be moving, and if you have motion in your eyes without motion in your vestibular system you get sick."
Anecdotal evidence has suggested simulator sickness is less intense when games contain fixed visual reference objects - such as a racecar's dashboard or an airplane's cockpit - located within the user's field of view.
Findings showed the virtual nose allowed people using the Tuscany villa simulation to play an average of 94.2 seconds longer without feeling sick, while those playing the roller coaster game played an average of 2.2 seconds longer.
"Our suspicion is that you have this stable object that your body is accustomed to tuning out, but it's still there and your sensory system knows it," he said.
