WorldSpace canvas at player location.

I'm trying to get a WorldSpace canvas to appear in front of the player when called, just like the OVRInspector in the sample framework. I cannot find anything in the code that controls where the interface appears. I've tried a simple follow script on a canvas with a public transform property for the OVRPlayerControler. But dragging any part of the OVRPlayerController into it seems to create problems for it. Can someone point me to the location in the SampleFramework code, or provide another direction. Thank you.
