Abstract: Embodiments of the present invention are capable of detecting a command issued by the user to lock a mobile device from receiving user input provided by input devices coupled to the mobile device, as well as the native buttons of the device itself, while an application executes. Provided the command is confirmed by the user, embodiments may proceed to intercept signals transmitted from input devices coupled to the mobile device and as well as from the native buttons of the device for the duration of the device's locked state. Additionally, embodiments of the present invention can provide users with visual notification of the device's current locked state. Furthermore, embodiments may operable remove the mobile device from a locked state in a manner that enables the application to resume receiving user input in a standard operational manner in response to detecting a subsequent unlock command issued by the user.

Abstract: Embodiments of the present invention provide a novel solution which leverages peripheral resources used during the performance of system wake events to detect the presence of gesture input provided by a user during power saving operations (e.g., sleep modes). During the occurrence of a system wake event, embodiments of the present invention utilize proximity detection capabilities of the mobile device to determine if a user is within a detectable distance of the device to provide possible gesture input. When a positive detection comes in, embodiments of the present invention may use the light intensity (e.g., brightness level) measuring capabilities of the mobile device to further determine whether the user is attempting to engage the device to provide gesture input or if the device was unintentionally engaged.
