Solved!: Oculus Rift tracking problems on motion sim

Solved!: Thanks to SeatTime and SilentChill for helping me fix this problem!

I can confirm this is a fix! Mounting the Rift camera near eye level and straight in front of your face fixes the problem. It may also need to be fairly close to your head. Right now my camera is about 20" in front of me, but I'm going to try moving it a bit farther away for better tracking FOV and see how it goes.

I flew (in DCS) the P-51D, Mig Trainer, and Huey for hours tonight with little to no head tracking issues!

Hey guys.

I'm having problems with head tracking when I attach my Rift camera to my motion simulator.

I have a video here I will show to demonstrate the problem but basically when the Rift camera is mounted to the motion sim my camera will frequently leap to a different location.
Check 3:20 and 3:39 to see the problem quickly

Check 3:20 and 3:39 to see the problem quickly


If I take the camera off of the motion sim and put it on my stand in front of the sim this problem does not happen at all, but then if I use decent travel on my motion sim positional tracking is a problem. I'm mostly stuck flying with no positional tracking then, which is a shame.

I have tried two different Rift cameras, several different mount locations for the camera, mounting two cameras at once... nothing helps. With two cameras the viewpoint jumped around even more.

This is happening in DCS world, and also was happening in P3D FlyInside a month or two ago when I was flying in that.

I have no idea where to begin to solve this problem, HELP!!!

Thank you all!

to same
This issue ever not resolved

Thanks for the reply Misoswan, I did not know if anyone else was having this same problem.

and try change . steel grip on rift camera maybe help slightly

too many people have this problem.

Been down this road before as in my 'that sinking feeling' thread. To stop the camera from spasmodically, jumping when it feels like it on big roll/pitch movements - mount the camera on a gimbal. Not a great solution, but it is the only solution that I have found at the moment. At least you keep heave/surge/sway mainly in step with the camera mounted to the rig. The issue is with the roll and pitch from the headset gyro, which the gimbal isolates.

You can also fit a G-seat (what I have done) and servo controlled belt tensioners (soon), which reduces the amount of roll and pitch that you need to dial-in to fool your brain in VR and therefore minimising the effect.

Thanks guys, I was hoping the gimbal thing might alleviate the problem.

I too have been considering a G-seat and especially belt tensioners but I'm now thinking just the belt tensioners.

Do you have a picture of your gimbal setup? I bought that same powered gimbal as some others used and pulled it out today to start making a camera mount to utilize it. The first thing I noticed is the cord tugging at it was too much for the gimbal to handle on the pitch axis.

Thanks for replying, now I know which tree to bark up!

Re: Gimbal - did a bit of Videoing in my past and you need to balance the load on the Gimbal to adjust for the cable weight - I do also own a high powered one (for bigger cameras) which would not be as sensitive to balance, but have not even needed to use either of late even for a reasonable amount of movement in No-limits 2 . Eg.

I don't really get any issues, I get thrown around quite a bit and the vibrations are pretty intense which you can't actually see. I think mounting the camera closer has always seemed to work for me.



You can see I have mounted the rift camera just above the steering wheel.

So that's two of you not having problems and not having to use a gimbal. That motivates me to try to figure out how/why that is so I can try to get the same results.

I tried mounting my camera on the front of my right side console the other day and it didn't seem to improve it any. Mounted there it was maybe 2 feet from my face, about a foot below the headset, but off to the side at maybe a 30 degree angle.

I will try to experiment and see what I can learn.

The position of my camera has never changed, with the DK2 I never had any jumping image issues at all, it was only when I changed to CV1 that this became apparent and I had to use a gimbal - in the last few iteration of the CV1 drivers the issue has seem to disappeared and I can now hard mount the camera (you can see it under the white velcro wrap in the video). As you can see in the video, I have the tracking camera quite close and almost level with CV1 headset, but note I did originally have the same issue as you and have not changed the camera position .

@SeatTime You mean you had the same issue as me, but prior to the most recent Oculus driver updates?

I notice both of you who aren't having problems have the camera mounted straight in front of the headset and about on level with it so I'm going to try that. The only problem is there is no quick and easy to securely mount it there with my current setup so I can't test it without some hours of preparation.

Correct, which is why I initially raised the thread and completed some investigations and fitted a gimbal, for me the video jumping went away I think two updates ago - have not needed a gimbal since.

try camera up higher more focused on the rift for stronger detection.
if you aint tried it yet.ps dont blame me tho if yaa misses can not find your broom after lol

LOL =P I'm still sitting here staring at my sim deciding how to get the camera just where I want it. It's a little bit more complicated with a center joystick setup and not wanting to butcher my beautiful rig!

This is certainly helping me rationalize that it makes sense to get started on that P-51D cockpit build I've been trying to talk myself out of.

/sigh Ugly plywood and 2x4 temporary mount it is.

Alright folks, I can confirm this is a fix! Camera near eye level and straight in front fixes the problem. Right now my camera is about 20" in front of me, but I'm going to try moving it a bit farther away and see how it goes.

Thanks for the help guys!

Yes, I red that a little on one lateral side is even better because the camera can even track the sensors on the side of the hmd.
Mine is about 80 cm from my head, a little on the rightside

I did what you said and I'm still having the same problem that you had. Is very frustrating
Did somebody else found a solution?
