Except it's not and it's a different phenomenon: http://www.cyberedge.com/info_r_a+p05_ss-es.html and a lot of people that get "motion sick" very quick don't get "simulation sickness" while wearing HMD and the other way around.
And it does go away after 2-3 weeks of getting used to it, getting slightly better each time.
But I'm sure you're an expert since people that have actually experienced it and people dedicated to solving said phenomenon and professionally working on it don't know any better...
Except that's a study from 1995 that clearly "concludes"
Although there is debate as to the exact cause or causes of simulator sickness
At that point in time they didn't know what it was.
How about a dictionary term for the medical definition of Simulator Sickness
http://medical-dictionary.thefreedictionary.com/Simulation+sickness
Motion sickness is the uncomfortable dizziness, nausea, and vomiting that people experience when their sense of balance and equilibrium is disturbed by constant motion. Riding in a car, aboard a ship or boat, or riding on a swing all cause stimulation of the vestibular system and visual stimulation that often leads to discomfort. While motion sickness can be bothersome, it is not a serious illness, and can be prevented.
Notice how it redirects you to Motion Sickness because Simulator Sickness is Motion Sickness.
There are 3 types of Motion Sickness
Type 1) Your Ears are telling your brain you're moving and your eyes are telling you you're still.
Type 2) Your Eyes are telling your brain you're moving and your ears are telling you you're still.
Type 3) Your Eyes are telling your brain you're moving in one direction and your ears are telling you you're moving in a different direction.
And if you understand Physics and Vectors you know that Type 3 is type 1 and 2 because it's a meaningless semantic difference between not moving and having motion in a different vector.
They are ALL motion sickness, and have the same Root Cause. Give the brain contradictory sensory data and it gets sick.
