What is eye tracking
Eye tracking is a feature on your Meta Quest Pro headset (also referred to as Meta Quest Pro device) that uses cameras to estimate the direction of where your eyes are looking. This feature is used to improve the image quality within the area where you are looking. Eye tracking may also be used as an input (similar to hand tracking), meaning you can interact with virtual content based on where you're looking. Eye tracking is not used to identify you. You can turn eye tracking on and off in Settings on your Meta Quest Pro headset.
How eye tracking works
When eye tracking is enabled
When you choose to enable eye tracking on the headset, software on the Meta Quest Pro headset analyses infrared images of your eyes ("raw image data") to create an estimate of where your eyes are looking ("abstracted gaze data"). This estimation is done on your device in real time as your eyes move. The raw image data is deleted from your headset after the abstracted gaze data has been generated. The abstracted gaze data is continuously generated and overwritten in real time as it provides this feature.
If another person uses your shared mode session on your Meta Quest Pro when you have enabled eye tracking, the raw image data and abstracted eye gaze data (collectively, "eye tracking data") from such person may also be processed unless they turn off the feature. You can only permit other people to use the feature during your shared mode session if you are their legally authorised representative.
How to enable eye tracking
For the device
To enable this feature for the device, navigate to Settings in VR, select Movement tracking and select Eye tracking. Toggle eye tracking on to enable it. You can disable eye tracking at any time by toggling the feature off in Settings.
What data is collected
Eye tracking function
If you choose to enable eye tracking, the raw image data is processed in real time on your headset and deleted once processing has been completed. We do not collect or store raw image data from the eye tracking feature on Meta servers. The abstracted gaze data is generated in real time on your headset, and processed on device or Meta servers to improve the image quality where you are looking, and/or to interact with virtual content.
We collect and retain certain data about your interactions with eye tracking as required for the feature to work properly and to provide the feature, consistent with our Privacy Policy. For example, we collect and retain information about tracking quality and the amount of time it takes to detect your eyes.
Headset crash logs
If your headset crashes, we send crash logs about your headset to our servers, which may contain recently generated abstracted gaze data and other information about your interactions with the eye tracking feature consistent with our Privacy Policy. Crash logs will not include raw image data of your eyes. Crash logs are deleted from Meta servers within 90 days, when no longer needed to provide eye tracking.
What data is shared with apps
If you enable eye tracking and the feature is used with a third-party app, the app will process your abstracted gaze data in accordance with the app developers' privacy policies. We do not control how a third-party app uses, stores or shares your abstracted gaze data, so you should only allow access to your data to apps that you trust.
