Hi Raanan,
Thanks for the reply. Yeah i don’t care at all where the user touches the screen, just that they have touched it, it is a trigger. This is how cardboard works in Unity for instance. The position is always directly ahead of the camera, ie the gaze direction. Touching the screen is just like pulling a trigger on a controller, for a controller the ray is determined by the orientation of the controller. For cardboard it is the orientation of the camera. I don’t see why they should be handled any differently. I got sidetracked on other issues today so didn’t get to progress it but i will pursue soon.
Thanks again for your input.
