Warning
IF YOU ARE READING THIS IN SEPTEMBER 2025 OR AFTER - NOTE THAT THIS TOOL IS NO LONGER RELEVANT.
Most OpenXR runtimes now support XR_EXT_eye_gaze_interaction, including SteamVR OpenXR. You do not need this API layer anymore.
- Quest Pro works out-of-the-box through Virtual Desktop, SteamLink and Quest Link (Developer mode)!
- PSVR2 (through PSVR2 Toolkit) works out-of-the-box!
- HP Reverb G2 Omnicept (through Oasis) works out-of-the-box!
- Bigscreen Beyond 2e works out-of-the-box (follow the setup guide)
This tool only support extremely niche combinations such as Pimax+SteamVR. YOU MOST LIKELY DO NOT NEED THIS.
If you are an OpenXR runtime developer, you may look at this implementation for inspiration. If you are a SteamVR driver developer, please use the new IVRDriverInput APIs to pass eye tracking data.
This software enables the use of eye trackers in HP Reverb G2 Omnicept, Meta Quest Pro, PlayStation VR2, Varjo Aero and Pimax Crystal by OpenXR applications, via the XR_EXT_eye_gaze_interaction extension.
Some examples of applications relying on OpenXR eye gaze interaction support and that can now be enabled on many headsets with OpenXR-Eye-Trackers:
- Microsoft Flight Simulator 2024 (Dynamic Foveated Rendering)
- iRacing (Dynamic Foveated Rendering)
- Quad Views foveated fendering
- OpenXR Toolkit dynamic foveated rendering
