You’re correct about motion, but that’s not my main concern. My main concern is range finding. The human brain uses parallax and eye focus information to figure out where objects are in space. All VR toolkits right now vary parallax for range, but can only produce light that is focused on one plane. This confuses the human brain, because it now has two pieces of information that disagree badly. This is actually why the Air Force abandoned its first attempts at HUD helmets, iirc the post I saw here said that the Air Force had to enforce a 24 ban on driving after using them, because your sense of range and speed would be wildly out of whack after using it. They were also worried about brain damage after excessive use. I’m glad that you like VR gaming, I personally found it to be novel but ultimately uninteresting after a few minutes.
