Eye tracking and foveated rendering
Android XR supports foveated rendering. This page supplements the OpenXR foveated rendering documentation and outlines how to configure foveated rendering on Android XR.
Enable eye tracking and foveated rendering
To enable eye tracking and foveated rendering, you must configure the following settings in the OpenXR section of the XR Plug-in Management settings:
- Add the Eye Gaze Interaction Profile under Enabled Interaction Profiles.
- Enable the Foveated Rendering feature from All features under OpenXR Feature Groups.
Refer to Configure project settings to understand how to configure your interaction profiles and OpenXR features.
Permissions
To use foveated rendering, you must request the android.permission.EYE_TRACKING_FINE permission. Refer to Request eye tracking permission on Android for more information.
Build profile
The Android XR build target from the Build Profiles window automatically enables the Android XR feature group and the Foveated Rendering feature in XR Plugin Management Settings window. Refer to Build Profile in the Unity manual for more information.
