Re Project cars/Dirt, they have the cockpit to ground you in the world despite the external movement. Cockpit based games are generally much better tolerated than free movement.
Agreed. The mind is smart, but it can be confused too. Because VR takes over your major senses (seeing, hearing) and puts you
there, it has to mostly react to what it sees there, even if it knows it isn`t real. It`ll be fine with things that make sense, like you`re in a car in a driving game, especially if you`re sat down. But if you`re walking about, the mind wants to know that you`re walking too or it starts to try and balance you, so you don`t fall over. It sees you walking but feels you not walking and the "gyro" in us becomes confused and you feel sick. This can even be more stark for a new user where the very basic lizard mind will auto-react.
Heck I remember when first starting VR, I`d played a few games, then tried my first zombie game. I told myself over and over again it was not real. I was doing ok. Then I was in a room, searching, and a zombie burst through the door and came at me. In shock I fumbled and dropped my gun, and as the zombie came at me, I frantically turned and ran -
for real! Straight into the room wall! lol. That was my lizard brain fight or flight acting over the conscious that knew it wasn`t real.
My subconscious and conscious are better trained now!
It would be fascinating to do a paper on how the conscious and sub conscious mind works on the Human mind in a VR game, especially regarding motion.
