#2That redirected walking video was weird... The guy walked what looked like about 10 feet forwards in VR and went what looked like twice as far in the enormous room that was at least 4x too small to get him to walk in a circle to continue the straight line...

#3I've been wondering if inertial engines could be placed on either side of a VR helmet, to combat motion sickness. When your VR avatar would be moving forward, the inertial engines would both pull backwards, hopefully tricking your inner ear. This could be extended to make all motion feel more natural.

#4Real-time graphics in general, not just VR, has always had "tricks" at its core. What has drawn me to that subfield of graphics is I think the collection of 'hacks' and deceptions that are needed for the user/viewer to buy into the virtual environment, whether on a desktop screen or in an HMD. There's an aspect of cleverness about it all that I enjoy -- from billboarding faraway objects instead of rendering them as 3D to baking static shadows into textures before runtime.
I wonder if there have been any in-depth articles examining comparisons between real-time graphics and stagecraft. The design of props and backgrounds in the theatre has similar objectives -- not necessarily fooling the audience into thinking it's real, but using a collection of 'tricks' to extend the capabilities of the stage to achieve greater effects. When attending a performance of The Nutcracker a few months ago, I found myself fascinated by how the multiple layers of forced-perspective backdrops offered a greater sense of depth to the stage.

Related: in [1] there's a VR version of the hyperbolic plane where there's "more space" than the Euclidean space we live in. So the person in the demo walks a loop and a half in order to end up back where he started in hyperbolic space. That group has some talks filmed on youtube that explain it in more detail if you want to listen, but I can't find the right snippet.

Can you further explain your “interial engine”? My understanding of physics says that it would only be able to actuate once then slowly “reset”, ruining the illusion if you’re moving in any steady state mannor

EDIT: Another thing this article makes me think about:
If you're interested in redirected walking, you might also be interested in the CyberMotion simulator [0]. I had the chance to see it in action when attending IEEE VR 2018. It's for motion sickness research, and it allows for mapping arbitrary motion into a limited robotic range of motion, in order to give a realistic sense of acceleration in different directions to the user.

Gyroscopes are used in satellites to change orientation. It should be possible to use one on either side of the head to simulate basic balanced inertia.

Ah. I was thinking linear inertia and you were describing rotational.
