  <p>To be more specific, where (on the hardware) the following method call (from <a href="https://github.com/ValveSoftware/openvr/blob/9d48ccf90d709382a137de9bc429aab5f7cea5de/headers/openvr.h" rel="nofollow noreferrer">OpenVR</a>) refers to?</p>
  
  <pre><code>virtual void GetDeviceToAbsoluteTrackingPose( ETrackingUniverseOrigin eOrigin, float fPredictedSecondsToPhotonsFromNow, VR_ARRAY_COUNT(unTrackedDevicePoseArrayCount) TrackedDevicePose_t *pTrackedDevicePoseArray, uint32_t unTrackedDevicePoseArrayCount ) = 0;
  </code></pre>
