Shaking image in HMD

When standing still, the image is visibly shaking. I can see up close objects and menus shaking. 4.4m playspace with base stations 6.6m apart and mounted tight to the wall studs. There are no reflective objects. Sync cable with B-C mode. Tried USB 3.0 and 2.0. This is the 2nd computer that had this problem. i7 8700K, 1080 Ti, 32GB 3200 DDR4. I've tried everything. Please, help.

As you've probably already guessed, the two main reasons you'd see shaking are environmental or base stations that aren't firmly mounted. Could you please send photographs of your play space? If possible, also try reducing your tracking space to test.

Since you used two different computers already I think it's safe to say that it's not a software problem and your PC specs are very good so that's not the issue either.

 

Thanks,

The TV screen is never facing the playspace. Even the recessed light bulbs are covered. The base stations couldn't be any tighter. They had one mount each from April 2016 until Dec 2017, when I added a 2nd mount to each in hopes that it would decrease vibrations. Tracking of controllers and games isn't an issue other than this close up menu/object shaking issue. If I'm in a car or cockpit in-game, I can see it shaking. There's ductwork in that lower part of the ceiling, but the shaking still occurs when there's no air on.

Can you take them down and test them just sitting on a desk or something on the ground? Just to rule out the walls shaking for whatever reason. I agree that reflection is almost certainly not the issue, given the images of your room. (Looks like a great play space, actually!)

Thanks,

Re: Shaking image in HMD

1. Do you have updates for Base Station, Controlers?

2. Vibration from the street?

3. Vibrating motor in the base station? Touch the station by hand.

 

The larger area = the greater vibration error .

Perform a new calibration.

Re: Shaking image in HMD

1. Fully updated
2. Vibration from street? I'm in a regular neighborhood with cars rarely passing. It's a big house.
3. Of course it's vibrating. They're vibrating if they're on.

Re: Shaking image in HMD

1. the base vibration is loud or normal?

2. try without Sync cable

3. Is shake reduced when you are closer to the base and look at it?

Synthesis, thanks. Here's the other side: https://imgur.com/gallery/SYIOp
I had this shaking image issue before adding those other machines, shuffleboard table, and picture frames. Are they far enough away to not be an issue?

Re: Shaking image in HMD

1. I only hear the regular high pitched barely audible base station sound.
2. I haven't tried that yet. Why would that help?
3. The closer I am to the base stations, the less shaking. The closer to the center I am, the more shaking. I don't want to have to make my playspace smaller. People with larger playspaces have said they don't have this issue. I'll do anything to fix this without sacrificing space. I bought this house partly for Vive space. Do 2.0 base stations fix this issue? If so, I'd buy them for over a grand.

Re: Shaking image in HMD

Hard to say, maybe people from HTC will know. I'm not a specialist, just thinking.

When the base station sees the other base station, do not need a sync cable.

 

maybe this

1. Powered USB extension cable

 

Then replace base station.

Very interesting. Do you know if it's one or the other than seems to be the culprit? In other words, does it happen more often when you're facing one direction? You said it gets better when you get closer, and presumably worse when you get further away.

It's very strange.

Thank you,

Re: Shaking image in HMD

The shaking reduces when I'm close to either one. The lower one might be better but, maybe, only because it's closer to my head. My only guess is vibrations. I want to reduce them as much as possible. I wonder if other people have the same issue but just don't notice it. For example, I've seen a lot of people on reddit that act like their subpar PC is running games perfectly when it would be impossible that they're not in major reprojection. I notice any reprojection immediately.

I'm trying to think of a good way to test that. Taking them down off the walls doesn't help or change anything? Set them on a chair or something temporarily.

Thanks,

Re: Shaking image in HMD

One more thing

1. it seems to me that the base station is too inclined down.

2. You can video shoot vibrations in HMD on a solid support in the center area. /Desk,Chair.../ for how much vibrations are.

3. Is SteamVR updated in your Steam account> SteamVR-tools-library

Vive has a very precise tracking, sometimes my hands/body shake and controlers or HMD too Smiley Happy

I tried the Vive Tracker on my heart and it is visible shake Smiley Happy

EDIT: Fixed by changing from usb 3.0 to usb 2.0. More details in this thread https://www.reddit.com/r/Vive/comments/4g7ym6/htc_vive_tracking_wobble_jittering_thread/d2wllqj Troubleshooting video to show tracking judder. This is a more detailed version of the previous judder video and features ...
