title: HoloLens user position
body: <p>Is there a way to get the position of the HoloLens user? I want to send the position of user back to PC and then update my hologram accordingly.
  Is there a way to do so? I haven't been able to find any API using which I can send back user's location to my computer.</p>
  
  <p>We can use the initial position and orientation of user as origin and then calculate everything relative to it.</p>
