title: How to check if Oculus Go controller on OVRInputModule is clicking on GUI object or not
body: <p>I'm a beginner of Unity and I've been trying to make an app for the Oculus go. So I implemented the Oculus go Controller working and some buttons on the screen. I can click the buttons and call the functions connected to the buttons. 
  What I wanna do is I want to trigger some action when the controller clicked on not UI buttons.</p>
  
  <p>I've tried these methods but I got false every time even if the button shows highlight color when the pointer is on the button.</p>
  
  <pre><code>Physics.Raycast(..)
  EventSystem.current.IsPointerOverGameObject
  </code></pre>
  
  <pre><code>Ray laserPointer = new Ray(rightHandAnchor.position, rightHandAnchor.forward);
  RaycastHit hit;
  bool hitOrNot = Physics.Raycast(laserPointer, out hit, maxRayDistance);
  </code></pre>
  
  <p>and </p>
  
  <pre><code>bool hitOrNot = EventSystem.current.IsPointerOverGameObject;
  </code></pre>
