How to get angular velocity and acceleration of headset

Is there a way to get the angular velocity and acceleration of the VR user (the headset itself) in unity? I am only looking for angular velocity and acceleration because the user will be stationary wh...

I haven't tried myself, but this might work:
OVRPlugin.Vector3f angularVel = OVRPlugin.GetNodeAngularVelocity(OVRPlugin.Node.Head, OVRPlugin.Step.Physics); OVRPlugin.Vector3f angularAcc = OVRPlugin.GetNodeAngularAcceleration(OVRPlugin.Node.Head, OVRPlugin.Step.Physics);
I'm not sure if the last parameter should be Physics or Render. I've seen Render used by someone on here in another thread.

Edit: I don't like posting things I haven't tried myself... so I just tested it.
The angular velocity part looks like it works correctly. The numbers seem reasonable.
The angular acceleration doesn't seem to work though, even with the headset sitting on a stable surface it has random values (positive and negative) on every axis.
