Thanks for the update. I had some doubts about the purpose of phone PT when it was first announced and still have:
When watching this on a phone screen, how would you align the scale of the performer with the scale of the real life furniture which differs probably by a factor of 10? It seems you would have to walk 20 meters away from your couch and my humble chambers will not allow that.
Moreover, I don't get how this should work during the POV sex parts. Even if the screen touches my nose, the performer's scale still is totally off.
If this was for cardboard VR, okay. But for flat videos that you watch with your phone in your hand? What am I missing?
