Tips for Starting with VR

Virtual reality (VR) motion sickness occurs when your eyes tell your brain you’re
moving around in an immersive environment, but your body feels like it’s sitting
in a chair or standing still.
Motion sickness is common for people not accustomed to mixed signals acting
on their inner ears while receiving information from multiple sources of motion.
If you’re experiencing motion sickness, it’s because your inner ear cannot tell
whether you’re moving or not moving.
When you enter VR, your eye perceives the virtual world as being a physical
space, because of how closely your head motion correlates to what’s in the
display. It’s why your brain gets mixed signals: Your eyes detect motion while
your inner ear doesn’t detect any motion at all. This is compounded by the nearly
imperceptible lag between commands and responses, causing you to feel sick.
The science behind all of this is complex, but what you feel is a fight between
your different senses to figure out what signals are right: the vestibular inputs
(concerned with balance and located in your inner ear), the visual inputs
(associated with your eyes), or the kinesthetic inputs (which assist in movement).
And that mixture of contradicting signals is too much for your brain to digest at
once, resulting in nausea and other unpleasant symptoms.
WARNING
:
You may experience sensations such as nausea, dizziness,
headaches, sweating, and/or excessive salivating.
Here are some tips for handling VR motion sickness:
•
Start out slowly, allowing time for proper immersion.
•
At any moment motion sickness occurs, shut your eyes and take short
breaks.
•
Remind yourself that what you’re feeling is normal, and that you’re going
to be fine.
•
Try having a fan aimed at you when using a VR system.
