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 (or proximity pattern, or characteristic pattern such as a capacitance pattern of a user'"'"'s finger) 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.

Claims

1. An electronic device comprising:

an interactive display having a sensor that detects user interaction with a sub-portion of the interactive display; and

a processing circuit configured to a state change of the interactive display from a low power state to an operational state in response to detected user interaction with the electronic device, wherein

the processing circuit is configured to perform the state change after determining that a detected capacitance pattern, caused by an object used to generate the user interaction, matches a preregistered capacitance pattern within a predetermined amount,

the one user interaction is a touch event against to surface of the sub-portion of a touch panel display.
