Viewing device screens in close proximity can cause eye strain. Some devices use front-facing cameras to detect and recognize faces in order to personalize the user experience (UX) to the user close to the device. However, such personalized operation does not include functionality that depends on the user’s proximity to the device screen. Proximity sensing within devices is used to turn the screen off in situations when the device is held against the user’s head. Such capacitive proximity sensing operates at distances from the screen that are relatively short. This disclosure describes techniques to change the operation of a device display based on detecting a user’s proximity to the device screen with the user’s permission. If the user permits, the user getting too close to the device screen can trigger appropriate measures that restrict the screen operation.
