In-game facial expressions or pre-recorded emotion data?

[NumesSanguis]

I just stumbled upon your project and I was wondering about this sentence "the human emotion data is streamed to a Unity character which is projected on a DIY pyramid hologram.".

Do you mean an emotion is detected, a trigger is send to Unity and the Unity character plays the pre-recorded emotion (although with some timing information?) or do you actually send the facial expression coordinates to the Unity character, making a copy of the user's facial expression in (running-/)real-time?
