So, if you work on studies with car simulators or flight simulators you find an interest reverse of this: "Simulation sickness." This happens when your body does not feel in motion but your eyes say differently. Psychologist have used simulation sickness as a way to combat motion sickness! They have subjects watch a simulation (I used someone else playing Halo, and it worked with that too) for short periods of time, slowly building up the individual's ability to handle the disparate information in the brain. It's a useful way to acclimate your body to the sensation. I could only watch 5 minutes at first, now I can go a full hour before feeling sick.
