User input method and apparatus in electronic device

1. An electronic device for operating in response to a user input, the electronic device comprising:

a user input device configured to receive a touch input and having an inner region and a peripheral region defined as an outermost area, with a user definable width, that has the ability to detect a touch or hovering state;

a memory configured to store therein a mapping relation between each of inputs from the user input device and each of operations to be performed in the electronic device, each of the inputs being identified based on a direction from the inner region to an outer region in a different direction, and each of the operations being mapped corresponding to a direction of each of the inputs; and

at least one processor configured to:

receive an input from the inner region to the peripheral region,

detect a direction of the received input, when the received input with a pressed button of the electronic device is detected, and

perform an operation mapped to the detected direction,

wherein each of the operations to be performed in the electronic device is mapped by the user, and

wherein the user definable width of each edge of the peripheral region is independently configurable.

2. The electronic device of claim 1 , further comprising:

a display configured to display thereon the operation when the mapped operation is performed.

3. The electronic device of claim 2 , wherein the at least one processor is further configured to control the display to display an absence of mapped operation when there is no operation mapped to the detected direction.

4. The electronic device of claim 3 , wherein the at least one processor is further configured to:

control the display to display a message for querying whether to map an operation together with or after displaying the absence of mapped operation,

control the display to display a list of available operations retrieved from a memory when a mapping is requested via the user input device, and

when a user selects one of the available operations, map the selected operation with the input.

5. The electronic device of claim 2 , wherein when the electronic device is in a document input mode for displaying an enlarged portion of a document, the operation mapped to the detected direction is at least one of a movement, reduction, or additional enlargement of the enlarged portion.

6. The electronic device of claim 1 , wherein the input from the inner region to the peripheral region includes at least one of a hovering input of an electronic pen, a drag input with a pressed button of the electronic device, a hovering input of the electronic pen with the pressed button, or a hovering input of a part of a user's body.

7. The electronic device of claim 1 , wherein the operation mapped to the detected direction is defined depending on a program or an application currently executing in the electronic device.

8. The electronic device of claim 1 , wherein the at least one processor is further configured to output a notification by means of at least one of a visual effect, sound, perfume, or vibration when the mapped operation is performed.

9. The electronic device of claim 1 , wherein the at least one processor is further configured to ignore the input when there is no operation mapped to the detected direction.

10. The electronic device of claim 1 ,

wherein the peripheral region is divided into two or more regions corresponding to activation regions of a program or application which is currently executing in the electronic device, and

wherein the at least one processor is further configured to:

identify one activation region corresponding to the divided region of the peripheral region from which the direction is detected, and

perform an operation mapped to the identified activation region.
