+# 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.
