Movement in VR is still tricky. Traditional FPS controls cause motion
sickness in most people, and while teleportation works it puts limits on
game design.
The Black Lodge is a VR artificial locomotion experiment that contains
several anti-motion sickness features in a test environment. The
anti-motion sickness modes are:
Grid on collision: When trying to walk through solid objects it shows the
room perimeter to prevent disorientation.
Grid on movement: Shows the room perimeter while using artificial
locomotion. This might help reduce motion sickness by giving a static frame
of reference to focus on.
Limit FOV: Research suggests limiting the field of view while moving can
help motion sickness so this reduces the FOV while using artificial
locomotion.
Snap rotation: Rotate in 45 degree steps instead of smoothly, as rotation
in VR seems to give more motion sickness than forward motion.
As well as these, different play styles may help reduce motion sickness
like standing and physically turning instead of turning with the controller.
Default control is with an Xbox controller but this can remapped to any
controller before starting. We've tested on Oculus Rift, and OpenVR support
is enabled in the build so it should work on Vive too.
