As you probably know, VR has been around commercially since the '90s, but it only became more widely recognized when Oculus and Vive headsets, which could be hooked up to a PC, became accessible. A short time thereafter, mobile phones were being turned into VR headsets as a cheaper alternative, examples including Google Cardboard and Samsung's Gear VR attachment headsets.
As a Unity Developer, we need to not only understand the technical limitations of these VR devices, but also understand how and why some people feel sick while others do not.
VR games/simulations can get rejected very quickly if, for example, the brain and the body know they are not inhabiting the world their eyes are telling them they are a part of.
