You don&#x27;t run video over the VR session, it&#x27;s all a 3D rendering. You have an avatar, and you correlate the HMD head movements to the avatar&#x27;s 3D model. Combined with simple hand tracking like Leap Motion, you get very natural body language of of it. Check out AltspaceVR for an example.<p>There are also some fairly recent advances in photogammetry that I think we will soon all have 1-to-1 avatars with our own faces.
