body: <p>I have attached a script to Vuforia AR camera component inorder to add buttons to Ar camera surface .</p>
  
  <pre><code>void OnGUI()
  {
      if (showComponent)
      {
          bool isOverlayClicked;
          int onePartHeight = Screen.width / 10;
          GUILayout.BeginArea(new Rect(0, 0, Screen.width, Screen.height));  // x,y,w,h
          GUI.backgroundColor = Color.clear;
          isOverlayClicked=  GUI.Button(new Rect(0, 0, Screen.width, (Screen.height / 2) + 100 + (onePartHeight * 2)), "");
          GUI.DrawTexture(new Rect(0, 0, Screen.width, (Screen.height / 2) + 100 + (onePartHeight * 2)), btntexture);
          thisMenu.blocksRaycasts = thisMenu.interactable = false;//disallows clicks
          thisMenu.alpha = 0;   //makes menu invisible
          if (isOverlayClicked)
          {
              Debug.Log("Overlay clicked in unity");
          }
          GUILayout.EndArea();  
  
          bool isProfileButtonClicked;
          GUILayout.BeginArea(new Rect((Screen.width) - (iconSize + (25 * DPinPixels)), iconSize - (30 * DPinPixels), iconSize, iconSize));
          GUI.backgroundColor = Color.clear;
          isProfileButtonClicked = GUI.Button(new Rect(0, 0, iconSize, iconSize), "");
          GUI.DrawTexture(new Rect(0, 0, iconSize, iconSize), profileViewTexture);
          if (isProfileButtonClicked)
          {
              Debug.Log("Profile icon clicked in unity");
              openProfileActivity();
          }
          GUILayout.EndArea();
      }
  }

  <p>Overlay Image click is always being called whenever I clicks the profile image.</p>
  
  <p>To your note:
  Overlay Image fills the entire screen.</p>
