Mesekai

Mesekai is a real-time motion tracking virtual avatar application. Use your physical body through webcam video to control the avatar's arms, fingers, head, and facial expressions. It supports personalized ReadyPlayerMe avatars.

The primary use case is Vtubing. Additionally, the motion tracking feature can be applied to a 3rd person online multiplayer game for immersive social interactions. Enter the hub world to try this feature with other players.
