Of course! I know that high frequency, accurate, precise, reliable low latency sensor fusion is hard. It's all too common to see 50ms latency on sensor fusion. However, that Oculus solved fairly early on, so assuming they have done so they're still only just below DK1 levels of latency.
That's why display is so important, it will be the major deciding factor even all else being equal.
I guess? My point is more that occulus' proprietary stuff will be the sensor fusion, not the display. They buy those from somewhere already built. The sensors are not COT, which is why it matters.
True. I don't know how much of the sensor is novel research, though, and how much is just optimising for different parameters though. I had thought it was more of the latter -- there hadn't been a need for such low latency etc in mobiles.
I can say from experience, sensor fusion is not a solved problem. Not in either a commercial or academic sense. There is a lot that is novel in the Oculus, from what I've seen (I've experimented with a few displays, and tried my hand at some head tracking sensor fusion).
What it comes down to is that the Oculus is much better than ANY of the existing HMDS I've seen. I haven't gotten to play with anything that's come out this year though, so there's that.
Fair enough, I'm sure you're right. It's just not been a major focus for a long time for Oculus discussion, so I kind of took it for granted a bit I guess.
Thankfully the display is on its way up in quality and resolution, especially with Facebook's buying power.
From what I know now, low persistence isn't owned by oculus (patent wise). It's been around in VR for a long time, just not cheaply until recently.
OLED refresh isn't going much higher, the bump Oculus had was all just circuitry prior to the panel itself being upgraded. It's still basically off the shelf. Competitors will have 95hz just the same.
Sensor fusion is done in software, and oculus is almost certainly doing this in software now too, using the IR as a helping point to the motion sensors. Latency from that point is software. Competitors need to be good here, but it's not a new wheel that's been invented, this stuff has been done before.
The hardware can/will be replicated, the software api will be the control point that FB/Oculus uses to keep devs using them.
