This is my fork of the workshop code that sends relaxation and focus metrics to vrchat avatar paramaters via OSC
Demos
Instructions
- See the document
INSTRUCTIONS.mdfor instructions on how to prepare your pc hardware, bluetooth, and install the base packages. Specifically: the intro, sections A1 and A2. Don't worry about muse-lsl. We'll replace that with the next step. - Instead of following section A3, download the Experimental version of Petal Metrics App.
- Install python-osc
- Turn on your Muse headset and click on Stream in the Petal App. The headset will connect automatically and stream data via LSL
- Run the script
python\osc_multichannel.py. That will start sending OSC messages to set Avatar Parameters
OSC Avatar Parameters
Avatar parameters being sent are floats that range from -1.0 to 1.0. Negative and Positive values correspond to low and high focus/relaxation. Left and right sides of the brain are measured and can be recieved by VRC seperately. Update your avatar paramaters as needed to influnece animations and the like. Have fun!
/avatar/parameters/osc_relax_left/avatar/parameters/osc_relax_right/avatar/parameters/osc_focus_left/avatar/parameters/osc_focus_right
Adjusting sensitivity per OSC path can be done by having float parameters in your avatar that are prefixes of the paramater name + '_tune'.
This will allow you to adjust how reactive the metrics are on the fly from your radial menu.
For example, having a parameters named osc_relax_tune will adjust the sensitivity for the paramaters:
/avatar/parameters/osc_relax_left/avatar/parameters/osc_relax_right/avatar/parameters/osc_relax_avg
While having a parameter named osc_relax_left_tune will only adjust /avatar/parameters/osc_relax_left
Interplay with other OSC programs
Considering that sensitivity adjustment requires receiving data back from vrchat, other OSC programs might fight over port 9001. The server part of this code has been changed so that it will forward vrchat messages on port 9002 by default. You can also change the receive, send, and forward ports in the OSC threads section of python/osc_multichannel.py (line 87)
Deprecated OSC Avatar Parameters
These paramaters have been deprecated. They will always report the left channels since taking the average of each side of the brain averages the noise as well:
/avatar/parameters/osc_relax_avg/avatar/parameters/osc_focus_avg
