My name is Hiatus, and I am one of the developers on the Project Babble Team.

For the past 2 years at the time of writing this, me and a team have been working on the eponymous Project Babble, a cross-platform and hardware-agnostic VR lower-face expression tracking solution for VRChat, ChilloutVR, and Resonite.

This blog post was inspired by a member of our community DragonLord. His work is responsible for this feature, and this blog post largely paraphrases his findings. Again, put where credit is due and check out his Github. You can check out his findings as well as his repo here.

This is the story of how the Vive Facial Tracker, another VR face tracking accessory was reverse engineered to work with the Babble App.

Buckle in.
