> I don't know what they consider their largest hurdle It seems like there are still plenty of challenges to solve with VR devices. John Carmack recently spoke [1] at the University of Texas at Dallas and mentioned that designing for VR is all about tradeoffs--hardware just isn't powerful enough to reach the ideal combination of resolution, framerate, etc. He also talked about how to design media to work well with the current generation of VR devices. For example he said to avoid accelerating the user, because this commonly causes users to feel sick (due to mismatch between what your eyes and inner ear are telling your brain). Moving at a constant velocity is fine. [1] https://www.youtube.com/watch?v=rBtXMtUNpdE https://www.youtube.com/watch?v=rBtXMtUNpdE
