Brainwaves on your avatar

Projects that turn a headset's signal into VRChat avatar parameters over OSC, and the plumbing they depend on. Star counts as of 8 October 2026.

BrainFlowsIntoVRChat

The reference project. Focus, relaxation, per-hemisphere band power, heart rate and trained thought commands, sent from any BrainFlow board to avatar parameters.

BFI VRCFT Module

A VRCFaceTracking module that maps BrainFlowsIntoVRChat's trained actions onto face-tracking expressions, so a thought can close your avatar's eyes or make it smile.

bci-workshop (VRChat fork)

The 2015 Montreal BCI Workshop material, modified to send relaxation and focus to VRChat. The seed BrainFlowsIntoVRChat grew from, and a readable place to learn.

BrainEmotionToVRChat

An experiment mapping brainwaves to emotion, trained against music with known mood labels and run through BrainFlow's ONNX support. Archived, but worth reading.

History · GPL-3.0

NextMindToVRC

An early client mod that let the NextMind visual BCI drive avatar parameters. The hardware was discontinued after Snap bought NextMind, and client mods risk a VRChat ban. Listed as history only.

Neighbours and plumbing

Other biosignals and the OSC layer

Brain projects rarely ship alone. These are the face, heart and OSC pieces they are most often combined with.

VRCFaceTracking

The standard OSC app for eye and face tracking in VRChat, with a module system that the BFI module above plugs into.

HRtoVRChat_OSC

Streams heart rate from a range of monitors onto avatar parameters. Archived, but still a clear example of a biosignal-to-OSC bridge.
