# EyeTrackVR
DIY eye tracking for any headset. Here are the steps to get the software working on linux.
## EyeTrackApp
`git clone https://github.com/EyeTrackVR/EyeTrackVR.git`
`cd EyeTrackVR`
`git checkout v2.0-beta-feature-branch`
`poetry install --no-root`
and it'll error because pysimplegui 4 is yanked. I dont know how to install yanked packages so just do this and it should work.
`poetry run pip install pysimplegui-4-foss`
`cd EyeTrackApp`
and bada bing bada boom you now should now have a fully functional eyetrack app when you run:
`poetry run python3 eyetrackapp.py`
## VRChat Native Eyetracking
VRCFT support will be added soon in oscavmgr. for now vrc native eyetracking works well. If you're having issues with your avatar cocnstantly squinting like I was, you can make a little change to osc.py at line 239 to correct that to your liking.
```diff
if self.config.gui_vrc_native: # VRC NATIVE
+ eye_blink = min(1.0, eye_blink * eyeblink_offset) # helps keep eyes open in VRC native eyetracking
if self.main_config.eye_display_id in [
EyeId.RIGHT,
```
This should only affect native eyetracking. replace `eyeblink_offset` with your preferred multiplier. I set mine to `1.8`
Squinting issues may also be caused by using IBO, so you may want to turn off "Intensity Based Openness" in blink algo settings.
## Current Bugs
Currently the app wont exit gracefully. when you close the window it will hang and you will have to ^C in the terminal to quit.
