Decolonise colons!
No. The vestibular system (the things in your ears that detect rotation and acceleration) cannot be fooled. If your visual system reports acceleration or rotation, but your vestibular system does not, then you will become nauseous. This is because visual/vestibular disconnect is a common symptom of poison, so it's an evolutionary benefit to puke when that happens, to get the toxins out of your body.
If the "camera" in VR acclerates or rotates without an exactly matching real-world head movement, then it can trigger this effect. Using a thumbstick to slide your character around is perfect example of this.
Interesting stuff. I have a little headset which I've played little VR games and videos with on with my phone - no ill effects but this has only been for a few mins at a time.
This PS4 VR is a bit of an expensive thing to buy if it makes you puke.
