An example of what I'm trying to achieve: <https://workshop.chromeexperiments.com/examples/guiVR/#1--Basic-Usage>

How could I get the Google Cardboard crosshair, (gaze)pointer, reticle, whatever you want to call it effect in three.js? I would like to make a dot, as crosshair, in the center of the screen in my scene. Like that I would like to use a raycaster to identify what I'm looking at in VR. Which way would be best to go here?

Do I fake an X and Y position of my mouse? Because I found other people have answered how to cover this [by adding an event listener to the mousemove event.](https://stackoverflow.com/questions/28872583/three-js-raycasting-from-a-child-camera-to-the-scene/28873205#comment69750197_28873205) But this works on desktop, and I want to bring this to mobile.
