The easiest way to not get sick in VR is to not “walk” around in the space, but “teleport”… gliding around like one would in a 2D video game works fine in 2D but 3D makes your brain eventually conclude you are moving without any of the inner ear action that is normally associated with forward movement… and you get sick. Teleporting is moving in small jumps, and your brain has no expectation of forward movement… it’s a bit visually jarring but no sickies.
