  • Patent number: 10216266
    Abstract: Systems and methods are provided that allow a user to interact with a device using gaze detection. In the provided systems and methods, the gaze detection is initiated by detecting a triggering event. Once gaze detection has been initiated, detecting a gaze of a user may allow the user to activate a display component of the device, pass a security challenge on the device, and view content and alerts on the device. The gaze detection may continue looking for the user's gaze and keep the display component of the device activated as long as a gaze is detected, but may deactivate the display component of the device once a gaze is no longer detected. To conserve power the gaze detection may also be deactivated until another triggering event is detected.
