Sensor managed apparatus, method and computer program product
First Claim
1. An electronic device comprising:
- an interactive display having a touch sensor that detects user interaction with a sub-portion of the touch sensor; and
a processing circuit configured to determine that a detected movement pattern, caused by an object used to generate the user interaction, matches a preregistered movement pattern,whereinthe user interaction is a touch event against a surface of the sub-portion of the touch sensor,the sub-portion being arranged in an adjacent area of a main portion of the touch sensor, andthe processing circuit is configured to perform visual feedback at a location corresponding to the sub-portion of the touch sensor when the detected movement pattern matches the preregistered movement pattern.

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.

15. A method for managing operation of a user interface in an electronic device comprising:
-
detecting with a touch sensor user interaction with a sub-portion of touch sensor; determining, via a processing circuit, that a detected movement pattern, caused by an object used to generate the user interaction, matches a preregistered movement pattern, wherein the one user interaction is a touch event against a surface of the sub-portion of a touch sensor, the sub-portion being arranged in an adjacent area of a main portion of the touch sensor; and performing visual feedback at a location corresponding to the sub-portion of the touch sensor when the detected movement pattern matches the preregistered movement pattern. - View Dependent Claims (16, 17, 18, 19)

20. A non-transitory computer readable storage medium having computer readable instructions that when executed by a processing circuit implement a method of managing a user interface in an electronic device, said method comprising:
-
detecting with a touch sensor user interaction with a sub-portion of the touch sensor; determining, via a processing circuit, that a detected movement pattern, caused by an object used to generate the user interaction, matches a preregistered movement pattern, wherein the one user interaction is a touch event against a surface of the sub-portion of a touch sensor, the sub-portion being arranged in an adjacent area of a main portion of the touch sensor; and performing visual feedback at a location corresponding to the sub-portion of the touch sensor when the detected movement pattern matches the preregistered movement pattern.
