Trying to figure out what makes people sick. Does it toy with equilibrium?
I IMAGINE it must give the impression of separating the head from the body. Two different worlds.
I also think of the old school stereo-vision toy Viewmaster, changing of depth perception. The human eye doesn't actually see in full 3d, the brain does? So I looked into it.
VR can make you sick because of a conflict between the signals your eyes and inner ear send to your brain (equilibrium), leading to a mismatch in sensory cues, similar to motion sickness. This is often referred to as cybersickness.
Here's a more detailed explanation....
Sensory Conflict:
Your brain relies on visual and vestibular (inner ear) cues to understand your position and movement. In VR, your eyes might perceive movement (like a character running in the game), while your inner ear might not be registering that movement, or vice versa.
Cybersickness:
This mismatch can lead to a range of symptoms, including nausea, dizziness, headaches, eyestrain, disorientation, and fatigue, collectively known as cybersickness.
Factors that Contribute:
Field of View: A narrow field of view in VR can contribute to cybersickness.
Frame Rate: Low frame rates can also cause issues.
Latency: High latency (delay between input and output) can also contribute to cybersickness.
Individual Susceptibility: Some people are more prone to VR sickness than others.
Mitigation Strategies:
Short Bursts: Start with short VR sessions and gradually increase the time.
Frequent Breaks: Take regular breaks to rest your eyes and inner ear.
Focus on a Fixed Point: Try focusing on a fixed point in the virtual environment to help your brain reconcile the sensory input.
Ginger: Ginger is a natural remedy for motion sickness and can help alleviate VR sickness.
Anti-Motion Sickness Medications: Consider taking Dramamine or other anti-motion sickness medications.
