VR may cause vomiting – Because of motion sickness

VR may cause vomiting – Because of motion sickness – In order to fully enter the virtual reality,
one has to deceive not only the eyes but also the other senses.
This is also the reason why
many virtual reality users can cause problems with motion sickness.
Then the impressions
received by the liar do not agree with the visual stimulus.
In motion sickness,
the eyes see that the body is not moving, and that the labyrinth registers continuous motion,
tilting and acceleration, in the case of nausea caused by virtual reality is quite the opposite.

Eyes see the perfect simulation of space, covering the entire field of view.

However, the brain does not record any motion signals from the labyrinth or other senses.

In both cases there is a sensual dissonance that causes malaise, dizziness, fatigue,
and even vomiting.
