Nice interview with John demoing and discussing his work: "So the way this has gone, is, I decided to treat myself after Rage on there, I bought a, you know, a head mount for $1,500 or so. It's a little cottage industry, there's a few places that do these things with integration, and... it sucked. It was really bad. It was everything that I expected it to be, that it, it didn't look like there had been any progress in 20 years, since... or 15 years since I had looked at these things last. But, when I got that, then, I started taking it apart, both literally and figuratively, to go ahead and see what are all of the aspects on here, on the sensing side, where, when I wrote my own test software for this, using their library to go ahead and get the head-tracking, it had 100ms of latency, and this just didn't make any sense to me. Why is it so bad, did they need to have so much filtering? And, I wound up, I took the software that I wrote for Armadillo Aerospace for our rocket control with fiber-optic gyros, I took that gyro integration software and took raw values from the micro-machine sensors on there, and all the sudden it got way better. You know I can only guess that they may have filtering from 10 years ago when they had really noisy sensors, and they're a lot better now." [...] Resolution is gonna get better. We're gonna get to 120Hz displays, I'm haranguing all the display vendors about this. [...] Removing the latency, one of the cases that I've been making that shows the
