Abstract: An apparatus, method and computer program product provide a simplified method for unlocking an electronic device that uses soft keys, such as capacitive touch keys, or proximity detection areas and patterns. The keys may be implemented in the form of areas of a sensor, and a processing circuit observes a touch pattern and compares the same with the registered pattern to determine if there is a likeness. In doing so, the electronic device is operated at a low power state, and in that low power state observes whether a predetermined pattern is observed and when it is, unlocks the electronic device for interaction with a user at a fully operational state. By operating in the low power state while waiting to observe a predetermined pattern before unlocking the user interface, the device does not waste power on false positive detections, and allows for convenient wakeup and accessibility by a user.
