As far as i recall, adding realistic movement in the screen helps
your brain accept the virtual environment. I think this is part of
the reason the 'walking' motion of the point-of-view was introduced
(Doom?).

I would theorize that the more 'true' or more calm the simulation,
the easier it gets, while ultra fast rotation and ultra even paths
of the viewpoint controlled by the player will cause more
uncomfort. Also, i would guess that rotation may be the most
influential factor in the problem?

Does anyone have some article references for this, or any knowledge
of what else have been done to reduce the problem?
