In the video, the central Hatsune Miku avatar is driven by optical motion capture of a real person on the left, while the Hatsune Miku on the right is driven by video motion capture based on the central Hatsune Miku.
You can see real-time motion recognition in the bottom left corner of the screen.
(Using anime characters as inputs for video motion capture is not best practice and is just for fun)
The motion is captured using Dollars MONO and streamed to Unity in real time.
(The original video was edited to retain only the cartoon character parts.)
