Good question. As a comparison we have been piling up dirt significantly longer than VR has been around and yet the physics of granular materials is still activ

  the software I was selling at the construction show in 1991 was essentially about piling up dirt. The reason I was there to sell it was that my software had a round up / "fudge factor" applied to the models, based on real world experience; where as the competition consistently under estimated things because they used the nice clean textbook formulas. Just because a machine has a 2.6 yd^2 capacity doesn't mean it will move that much dirt per load. And so on. Applying back to the original discussion of VR; I expect there's been enough time and enough experience with the things like head mounted displays that there shouldn't need to be much original research into "how to do the optics" of same. I'm ignorant of optics generally (and much else) but there should be textbooks and people arguing over where those are wrong and such; by now. For this specialized purpose even. See the amount of literature on LCD displays by comparison; the basic optics there are known, right?

    We did just have a major breakthrough in HMD optics not more than 10 years ago with "pancake optics" that have only started making it into devices you can actually buy within the last year or two.
