While we've successfully solved the problem of how to make VR users look like idiots, one solution we haven't settled on is how to provide a realistic sensation of walking. Proposed solutions differ widely. The Infinadeck is an omnidirectional treadmill:
Cybershoes are a wearable solution, but they require you to sit-stand:
Incredibly, it appears that the way they work is, there are wheels in the boots that attempt to return you to your original position as you stride:

As you can see, the boots are so chunky that they affect a good portion of the testers' gaits. I can't see this being an effective solution until they get slimmed down, and I do wonder about losing your balance while walking around on rollerskates designed to counter your natural locomotion.
To solve the walking-in-VR problem, my suggestion was to use a grid of ball-transfer-style outfeed rollers hooked up to sensors:
The only problem is that I don't have any financial backing, technological acumen, proof-of-concept, ambition, etc.
What are your predictions for the VR future, will the solution be treadmill-style or wearable? Or a third thing no one's thought of yet?
