Oculus: Is player looking at Object A ?

Hello everybody,

so far i have used this code to check if player looks at objects:

 var ySize = Screen.height*percentageOfScreenHeight;
     centerRect = Rect(Screen.width/2 - ySize/2, Screen.height/2 - ySize/2, ySize, ySize);
 
 
 if (centerRect.Contains(Camera.main.WorldToScreenPoint(transform.position)) && renderer.enabled ) {
     TimerForLooking += Time.deltaTime;   
     }

and somehow the same code does not work, if i use the character from the rift sdk.

Is there any chance how to see if someone looks at an object, but with with the rift?

Getting really desperate ...

thank you !
