## What it is
EyeTrackVR is a free, open-source, DIY software platform that turns affordable cameras and IR LEDs mounted inside a VR headset into an eye tracker. It streams eye-tracking data to social VR applications like VRChat, ChilloutVR, and NeosVR via OSC and UDP.

## Use cases
- add eye tracking to a VR headset that lacks it
- get eye tracking working in VRChat avatars
- build a DIY eye tracker with ESP32 and IR cameras
- stream eye data to social VR games over OSC
- make VRChat avatars blink and look realistically
- affordable alternative to headset eye tracking add-ons

## When to choose
- you want free or low-cost eye tracking for social VR
- you are comfortable building and mounting small hardware yourself
- you use VRChat, ChilloutVR, or NeosVR and want expressive eye movement
- you want a privacy-focused, locally hosted solution

## When to avoid
- you need plug-and-play eye tracking without DIY assembly
- you are unwilling to handle IR emitter safety precautions
- you need production-grade, fully finished software
- your headset cannot physically fit cameras and LEDs
