VR Motion Cancellation - Time to test!

you are using this workaround yourself? i read somewhere that its not totally necessary - will have to try it out. still building the bloody rig (3 days later)

I am using it. Trying to fly without it is no fun. Having said that I haven't used the rig in weeks as I still find it flaky and I don't like running in SteamVR mode. My interim solution is to build a G Seat - no actual movement, just the forces are felt.

ive read its not as much of a problem for sim racing - which is all im doing

As far as I know yes. =( I really wish Oculus would add motion cancellation. I even tried switching to Vive but just couldn't deal with the reduction in image clarity and performance (performance difference being ASW). I sold the Vive after a few weeks of testing, at a significant loss.

Also so you are aware, this solution is generally incompatible with shakers. If you can isolate the motion controller from the vibration you can get around this but that's not as easy as it sounds.

Just tried this and it worked quite well
Not quite as smooth as with ASW on but the head doesn’t vibrate like fook anymore!

struggled with motion sickness during dirt rally . Think I need to just reduce the overall effects of the rig during this one maybe

Last week after a long period I tried to optimize motion in combination with VR. Basically without motion cancellation it's impossible to feel real on the rig. Shaking doubles the overall effects and nausea is the consequence. Especially on a seat shaker...

It seems to me that this tiny widget does the job of vive's tracker for a fraction the cost and size and could be a great oculus solution for motion cancellation.

I bought a bunch of these to mount the seat on which seems to be helping as the shakers are fixed to the seat. I mount the tracker on the rig rather than the seat - not ideal for cancellation calculations, but I'm going to build some brackets to move it as close to my head as possible.

I've tried oculus CV1 and have the same problem. I have 6dof that can do 30 degree roll, yaw, pitch so it is very apparent. It seems rotational compensation does not work and the view area goes out of headset view causing blank black area to show instead. I've been struggling with this problem since yesterday. Can anyone else confirm this is a known issue so that i can perhaps move on to other solutions. @SilentChill, are you using older version of oculus runtime and that it is working for you and not have this problem?

Do you have this problem on any other games e.g Asetto Corsa? From your last post in matzman github, it seems like you are still using CV1 for your project.

From reading this thread no one got VR working properly on 6dof motion simulator yet well enough yet.

I am thinking the solution is pledging for pimax 8k with the base stations but i am skeptical about the vibrations from bass shaker still affecting the HMD IMU accuracy. The alternative is welding a mount for the good old conventional lcd monitor; most likely will go for 21:9 ultrawide 29 inch monitors. I am still hoping VR will work on motion simulator though, they are so meant for each other.

I haven't had any luck, but I've only tried in DCS and Dirt Rally. SilentChill had it working at one point at least, I sent him a PM hoping to find out if it still works for him and if so how he is doing it.

I am using CV1. Currently I'm only flying and just using smaller movements. To get racing I need the motion compensation. I'm also hoping that the LG SteamVR headset will actually come out in 2018 and that it will have a display that looks at least as good as Rift CV1 (Vive is far inferior).

There is also one other thing, if we are willing to pay for it I'm almost certain we can get the guy who makes DRIVER4VR to work on this for us since MatzMan666 dropped off the grid. I'd absolutely be willing to pay a fee myself for working motion compensation. How about you guys?

I really, really badly wanted to switch to Vive because of the motion cancellation but couldn't stand the difference. Mostly the lenses, the sweet spot was small to an extreme for me and everything off dead center was blurry as hell. Also to me I feel like the Vive display pixels look like 3D little bumps, weird I know.

Palmer Luckey implied at one point that the LG VR headset might not actually happen, and the long silence coupled with that has me a bit concerned. The headset was shown again recently, but as near as I can tell it was still the same prototype which is concerning.

Don't get me wrong, what I want most in the world of VR is a headset upgrade that runs natively on SteamVR. I believe in that platform and want in on it. Even now as I sit here I am questioning myself "was it (Vive) really that bad?". The answer however I'm confident is "yes", I exhaustively compared the two for over a month before I sold the Vive (and took a beating in the process).

As I expect to be using '8K' Pimax sometime in the new year, I'm hoping that the motion cancellation will work as advertised with a native Steam VR system.

I don't get the beef with the Vive. I've tried both and much prefer Vive to Rift but that's my own opinion. There is more screen door but it's not excessive but since they have the same number of pixels, the tradeoff is more field of view in the Vive. And the tracking for me is flawless. I still haven't fired up motion cancellation on my 2 dof, but from what I hear Vive motion cancellation works great but Oculus changed their driver somehow that broke it and it remains broken. Even at the current price on CV1, I'd still rather pay the bump and have a Vive. For me it's just that much better and I don't have to string cameras or deal with any of the other stuff.

I know everyone will have their own preferences but for me it's Vive hands down. And for whatever it's worth, I was told by a guy from Valve that SteamVR will eventually have native motion cancellation. He didn't say when or what the status was, but it's coming supposedly at some point.

I can confirm it!
I bought the vive to compare it , it is totally worth compared to the oculus CV1 in terms of image quality , blurryness and sweet spot.

No doubt that each has advantages and I didn't mean to trash-talk the Vive. I think it partly depends on what you are playing. The DCS World community pretty much unanimously agree that Rift is far better than Vive, but that is because we are constantly trying to see detail at long distances.

One of my main tests was sitting on the pad in a Huey while a C130 took off from the nearby runway. I ran this with the exact same parameters with Vive, Rift, and Pimax many times over. With Vive the C130 was basically a slightly blurry silhouette. With Rift I could see the shape of the aircraft clearly. In that same scene there was also a treeline maybe a mile away and in the Rift I could clearly make out individual trees where with Vive the treeline was more of a treeline shaped blob.

The cockpit on the other hand looked just fine in Vive. Pimax of course was clearer than either, except with my own physical IPD of 67.5mm vs the fixed physical (63ish I think I heard) IPD of the Pimax headset and lack of fresnel lenses the Pimax headset was like being permanently cross-eyed. For Pimax it seems the lower your IPD the better, being a couple mm obove average I couldn't use it.

I really appreciated the increased vertical FOV of the Vive and the motion compensation was great but there was too much blurriness and it caused a lot more eye strain for me. The screen-door effect didn't much bother me.
