title: On-screen button for A-frame AR
body: <p>I`m trying this for days and I need help, please! What I need is two buttons on-screen overlaying the ar-camera picture reacting on touch. I tried two a-planes inside the the camera entity and I added <strong>cursor="rayOrigin: mouse"</strong> to a-scene (A-Frame 0.8.0). Somehow <strong>cursor="rayOrigin: mouse"</strong> blocks the aframe-ar.js to open the cam.</p>
  
  <p>So, is there another way, maybe creating 2 buttons via js or html to switch objects on/off?</p>
