In the demo there is a scene where a guy displays some iceberg photo on a virtual screen and then moves closer to it, with the screen anchored to some 3D point in the real world.
They kept doing that, like the woman sitting on the sofa watching a film leans down towards her popcorn[1] and the screen doesn't move, or the woman lying in bed watching the ceiling change into a blue sky[2] instead of just a blue sky where she was looking.
