Sensor managed apparatus, method and computer program product
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.
1. An electronic device comprising:
a display;
a first area and a second area related to the display;
circuitry configured to
detect user interaction with the second area, wherein the second area includes a plurality of input receiving objects each configured to receive an individual touch event from the user to perform a different respective function to perform control on an object or information displayed on the display; and
execute a display state change of the display, including the first area and the second area, when the detected user interaction with the second area corresponds to predetermined touch operations that are performed over at least one of the plurality of input receiving objects,
wherein the predetermined touch operations are tap operations, and the tap operations are sequential tap operations.
2. The electronic device of claim 1 , wherein the tap operations are a same tap operation.
3. The electronic device of claim 1 , wherein the tap operations are three tap operations.
4. A method, implemented by an electronic device that includes a display, and a first area and a second area related to the display, the method comprising:
by circuitry of the electronic device,
detecting user interaction with the second area, wherein the second area includes a plurality of input receiving objects each configured to receive an individual touch event from the user to perform a different respective function to perform control on an object or information displayed on the display; and
executing a display state change of the display, including the first area and the second area, when the detected user interaction with the second area corresponds to predetermined touch operations that are performed over at least one of the plurality of input receiving objects,
wherein the predetermined touch operations are tap operations, and the tap operations are sequential tap operations.
5. The method of claim 4 , wherein the tap operations are a same tap operation.
6. The method of claim 4 , wherein the tap operations are three tap operations.
7. A non-transitory computer-readable medium for storing therein a program that includes instructions which when executed by a processor of an electronic device that includes a display, and a first area and a second area related to the display, causes the electronic device to perform a method comprising:
detecting user interaction with the second area, wherein the second area includes a plurality of input receiving objects each configured to receive an individual touch event from the user to perform a different respective function to perform control on an object or information displayed on the display; and
executing a display state change of the display, including the first area and the second area, when the detected user interaction with the second area corresponds to predetermined touch operations that are performed over at least one of the plurality of input receiving objects,
wherein the predetermined touch operations are tap operations, and the tap operations are sequential tap operations.
8. The non-transitory computer-readable recording medium of claim 7 , wherein the tap operations are a same tap operation.
9. The non-transitory computer-readable recording medium of claim 7 , wherein the tap operations are three tap operations.
