Claim:
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 change a state 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 user interaction is a touch event against a surface of the sub-portion of a touch panel display, the sub-portion being arranged in an adjacent area of a main portion of the interactive display and including a plurality of soft key regions that include at least a first soft key and a second soft key, and the touch event includes a movement across the soft key regions that include the first soft key region and the second soft key region.
