The video embedded above shows cool new HoloLens tech from Microsoft Research, which can create 3D models of people in remote locations and project them into the room you're in -- tech that could be used for games as well as Skype-like video conferencing, the use that it is put to in the demo. 

HoloLens, at $3,000, is still far from being a consumer product -- but this demo shows the appeal and its potential for game developers.

What's also notable here is that there are views of the in-device experience periodically in the bottom-left corner of the window, giving a more "honest" look at what the experience will actually feel like.

It's also worth noting that Meta has developed similar remote-meeting technology for its AR glasses, which we got to try out at GDC -- and which worked well. That company is currently taking preorders for its new dev kit at $949.
