BFI VRCFT Module 🧠

A VRCFT module that let's you control VRCFT avatars using BFI expression actions controlled by your brain 🧠

Supported expressions 😀

List of supported expressions not set in stone yet

Reference	Expression	Description
	eyeclosed	eyelids closing fully

	cringe	mouth stretches and reveles the bottom teeth
	cheekpuff	cheek puffs
	apeshape	lower jaw while keeping the mouth closed

Tested hardware 🧰

While this module is compatible with any Brainflows compatible boards, training facial expressions has only been tested with the MuseS and Muse 2 headbands thus far.

Please get in contact if you try this with a different device so I can list it here 😊

How to use 🤔

1 - Train your expressions as BFI Actions🏋️ :

Make sure you've trained your actions

Here's BFI's documentation on how to train your own actions

2 - Get data into the module 💨

You've got a couple ways you can go about doing that but using an OSC mixer is recomended to remain compatibility with your BFI parameters compatible avatar.

OSC Mixing 🎛️

We'll use VOR but the setup should be about the same with any other OSC mixing software:

• Select a port for BrainFlows

• Configure your routing

• Launch BFI

  python .\main.py --board-id=YOURBOARD --enable-action --osc-port=9002

Directly output to the module ➡️

Here's the command to launch BFI with the right launch option if you leave the port on the default setting:

python .\main.py ----osc-port 8999

⚠️The port can be configured at the bottom of config.json

3 - Install the module 📁

Go to VRCFT's modules registery tab, click the + button and select the latest release of the module 📁

4 - Configured your supported expressions based on your trained actions 🤓

config.json must be in the same folder as the module and is used to define which expressions you have trained and which action number it's assigned to and it's overhall weight.

Here's an exemple of a config.json supporting all of the supported expressions thus far:

{
  "supportedexpressions": {
    "eyeclosed": {
      "id": 1,
      "weight": 1.0
    },
    "smile": {
      "id": 2,
      "weight": 1.0
    },
    "frown": {
      "id": 3,
      "weight": 1.0
    },
    "anger": {
      "id": 4,
      "weight": 1.0
    },
    "cringe": {
      "id": 5,
      "weight": 1.0
    },
    "cheekpuff": {
      "id": 6,
      "weight": 1.0
    },
    "apeshape": {
      "id": 7,
      "weight": 1.0
    }
  },
  "ip": "127.0.0.1",
  "port": 8999,
  "timouttime": 3.0
}

5 - Launch VRChat and switch to a VRCFT compatible avatar

VRCFT compatible avatars can be found by searching for VRCFT or Face Tracing in Prismic's Avatar Search world
