How to disable Oculus head input tracking

Archived Forums Questions & Answers

Dear all I need to set my camera to be fixed and pointing to the same position regardless of the head movements.

I’ve found UnityEngine.VR.InputTracking.Recenter() where I can recenter, but it’s probably not the best option to use in update method …

Can I somehow disable headtracking and set camera position to be fixed?

many thanks

Any news on this topic?

I had the same problem with the HTC Vive, now it may not exist, but with the SteamVR package I dug into the positioning of the SteamVR objects, (SteamVR_TrackedObject.cs) which had a couple lines of code in there for positioning a given SteamVR object - in that case I didn't need the Vive controllers so I was able to have it be a general hack. I haven't played with the Oculus plugins so this may not exist, but perhaps there's a positioning script in the Utilities you could find and put a couple of booleans to control?

Found the solution.

When you say head input tracking, I assume you are referring to the Position Tracking.

To disable it:

  • First import the Oculus Utilities
  • In the folder OVR-> Scripts, there is a script called: OVRManager. Add this script to your camera.
  • Deselect the option “Use Position Tracking”

As simple as that.

it doesn't work for me, still tracks head position

You’re probably going to need to selectively disable and rewrite parts of the Oculus plugin code to do so. I don’t believe it’s written into the framework because it simply should not be done. Head tracking is enabled even in loading screens for Oculus because turning it off is a one-way trip to vomit town. Our brains aren’t good at handling a sudden loss of autonomy.

I was synchronizing Oculus camera/player controller with 3Drudder so had to find and override Y rotation.

For all three axis must work like this:

OVRi/Assets/OVR/Scripts/Util/OVRPlayerController.cs at master · real7a/OVRi · GitHub line 326

transform.rotation = Quaternion.Euler(euler);

change to = Quaternion.identity for fixed zero orientation;

Hope it helps :slight_smile:
