PicoBridge - C# Library for parsing face-tracking data from PICO headsets

A C# library for parsing FT data from PICO 4 Pro.

PicoVRCFTModule - PICO 4 Pro Module for VRCFaceTracking 4.0

Note: If you are using the newer version of VRCFaceTracking (that runs on .NET 7), then try out Mitchell Taylor's Implementation.

Setup

1. (TBA by PICO) Download and install the latest Streaming Assistant for PICO
2. Remove or rename pico_et_ft_bt_bridge.exe in %StreamingAssistantInstallationDirectory%\driver\bin\win64. Typically it's in ?:\Program Files (x86)\Streaming Assistant\driver\bin\win64 where ? is a drive letter
3. Download the latest module file from Release
4. Put both PicoBridge.dll and PicoVRCFTModule.dll into %appdata%\VRCFaceTracking\CustomLibs
5. Start VRCFaceTracking!

Road Map

• [x] Basic gaze tracking
• [x] Eyelid support
• [ ] Basic expression support
• [ ] Viseme support

Known Issues

Eye closing is not properly mapped

Some avatars may not respond to eye closing. This is a known issue that we are investigating.

Expressions are always mapped to frowning / sad face

Expression support is still under development. It seems that PICO's data doesn't map cleanly to the formats of other vendors. We will need to convert them.

Troubleshooting

Port already in use. Run PICOBridgeHelper.exe first!

Please make sure that you have removed pico_et_ft_bt_bridge.exe and restarted Streaming Assistant. Should the problem persists, please report it in the Issues.
