Question VR Head/Camera Collision?

[TripleR]

I started making a scene where the Camera Rig was parented to an Empty Atom so that I could trigger when it went inside of the area of a Cube. This works in desktop but the Camera Rig doesn't seem to be the default view in VR because the Empty Atom doesn't follow my VR head in the scene. What should I be calling when it comes to collision triggers and the VR head/camera?
