The status of the research should be the same as that of motion
sickness in general, i.e., decorrelation of visual and vestibular 
inputs is often thought to cause motion sickness. One well published 
example is space sickness, a common example is motion sickness from 
riding in an automobile (car sickness). 

Check your library for medical/psychological journal articles on 
motion sickness -- much has been done.
