> photorealistic avatars.
It's coming, to, of all things, Second Life. Second Life is adding "puppeteering", and this works with head tracking, face tracking, and full body tracking. Users have been working on VR viewers. (The client is open source.)
It's all very experimental, but there is a meeting in Second Life every two weeks[1] where all of this is demoed. Some of the attendees are rigged for full body tracking, and, with good quality Second Life avatars, which have far more detail than Meta or VRChat, and can do facial expressions, they look reasonably good. It's striking how someone with a full rig dominates a meeting without even trying. They're so much more present than the people sitting at keyboards.
Hardware is a big problem. You need a good gamer PC to run all this and get the full effect.
And a VR headset. And tracking gear. This is a real problem in the era of the $99 Chromebook. It's not getting cheaper, either. The first NVidia graphics card that was good enough for this was the NVidia 1060 with 6GB VRAM, in 2016, introduced at $250. It still costs about $250 to get that level of GPU power from NVidia.
People who really want to be looked at - performers, influencers, etc - will need a full tracking rig. The audience doesn't.
