Looks like a serious attempt at an ambitious concept. I love how the video showcases what seems to be an actual working prototype, with its capabilities and imperfections – as opposed to the usual trend of AR 'demo' videos that are actually just mockups, and completely unrealistic ones at that (as seen with Google Glass, Pokemon Go, and Magic Leap, just from memory.) I'm curious about the hardware. Is there a base station or two hiding in a corner somewhere? If there is, why isn't head tracking accurate enough to prevent "sway" of virtual objects with respect to real-world ones, which seems to be visible in the video? But if not, how does it capture the position and pose of the user's hands? In any case, what kinds of sensors are being used? Unfortunately, when watching the video, what really stands out is that the 3D "ghosts" of the other participants have juddery, unsmooth motion. Surely it couldn't hurt to add a bit of interpolation? It would increase latency, but not by much, given that a user's view of a different user's body pose is not especially latency sensitive. Edit: On second look, it seems like the HMD is just a Magic Leap One, though that doesn't answer the question of whether there's other hardware in the room.
