Device screens are often set to turn off and/or dim automatically if no user interaction is detected for a specified amount of time. Turning off or dimming the screen saves power and prolongs the amount of time the device can operate without needing to recharge the battery. However, such timeout-based actions can result in false positives or negatives. With user permission, this disclosure utilizes contextual input of a user’s gaze and attention for management of the automatic turn off or dimming of the device screen. The techniques are applied to reduce the false positives and negatives and ensure that the screen stays on longer if the user is still engaged with the device and turns off or dims before the timeout if the user has stopped using the screen.
