In Windows 10, having an eye tracker as part of your device or system enables you to control your PC with only your eyes, enjoy more immersive game experiences, assist those with reading difficulties, and more. Some apps and services request permission to access your eye tracker, and you can always control which apps can access your eye tracker in Windows settings.
Microsoft wants to inform you about these new eye-tracking capabilities so that you can decide whether they’re the right choice for you when using your Windows device. This page describes the eye tracker settings that are available to you and how they work.
How to control which apps can access your eye tracker
The first time an app needs to access your eye tracker, it requests your permission. If you give an app permission, but you change your mind later, you can turn off that app’s access to your eye tracker in Settings > Privacy > Eye tracker and under Choose apps that can access your eye tracker, switch the individual settings for apps and services to On or Off.
Note: Some apps might not work as intended if you choose to block them from accessing the eye tracker on your device.
You can also turn off eye tracking for all apps by going to Settings > Privacy > Eye tracker and switching Let apps use my eye tracker to Off.
Exceptions to the eye tracker privacy settings
If an app accesses the eye tracker using a service that’s different from the one offered by Windows, it will not appear in the list under Choose apps that can access your eye tracker and will not be affected by the Let apps use my eye tracker setting. To allow or block an app like this, change the settings within the app or the settings for your eye tracker.
