The Virtual Human: Hellblade
I found this video amazing; it is an explanation of how they used a real person to create a game character, and in the process invented the combination of technology needed to allow that person to act in real time in the game. Which means that anyone with deep enough pockets (which would have to be very deep, at this point) could schedule time to get themselves scanned and processed, buy the gear including the head mounted camera system, and do the same thing. It allows you to be fully immersed in the 360 VR game environment as yourself, with everyone able to see and hear you, right down to your current facial expression. Of course, it will be a decade or so before the price comes down enough that the rest of us get to try this out, but its good to know it is on the way.
