Abstract

A method for processing a letter input in an electronic device is provided. The method includes, if at least one letter is input, determining at least one input behavior related to the input and if a predetermined delimiter is input, determining whether to disable a function of automatically recommending at least one word similar to an input word, based on the determined input behavior.

Claims

1. A method for processing a letter input in an electronic device, the method comprising:

when at least one letter is obtained, identifying a manner of a touch input for the at least one letter;

obtaining an input word including the at least one letter;

in response to identifying a first manner as the manner of the touch input, displaying a first recommended word similar to the input word, wherein the at least one letter is changed to a letter in the first recommended word; and

in response to identifying a second manner as the manner of the touch input, displaying a second recommended word similar to the input word without displaying the first recommended word, wherein the at least one letter is maintained in the second recommended word,

wherein the input word, the first recommended word and the second recommended word are different from each other, and

wherein the first manner is identified based on a touch for an input held within a first predetermined time range and the second manner is identified based on a touch for an input held within a second predetermined time range different than the first predetermined time range.

2. The method of claim 1, further comprising:

obtaining a predetermined delimiter received next to the input word;

in response to obtaining the predetermined delimiter, determining whether to disable a function of automatically recommending a word;

in response to identifying the first manner or the second manner, enabling the function; and

in response to identifying a third manner as the manner of the touch input, disabling the function and displaying the an input word including the at least one letter intact.

3. The method of claim 2, wherein the third manner is identified based on a touch for an input held longer than the second predetermined time range.

4. The method of claim 2, wherein the third manner is identified based on a touch for an input being made with a pressure greater than or equal to a predetermined value.

5. The method of claim 2, wherein the third manner is a manner based on a touch for an input being made with an area greater than or equal to a predetermined value.

6. The method of claim 1, wherein the manner of the touch input includes at least one of a time for which a touch is held for an input, a touch pressure, a contact area, or behavior of a gesture.

7. The method of claim 1, further comprising:

expanding, based on a touch in a keypad area being held for a predetermined time or more, the touched keypad area or a perimeter of the touched keypad area by an amount greater than or equal to a predetermined value or more.

8. An electronic device comprising:

a display; and

at least one processor configured to;

when at least one letter is obtained, identify a manner of a touch input for the at least one letter,

obtain an input word including the at least one letter,

in response to identifying a first manner as the manner of the touch input, control the display to display a first recommended word similar to the input word, wherein the at least one letter is changed to a letter in the first recommended word, and

in response to identifying a second manner as the manner of the touch input, control the display to display a second recommended word similar to the input word without displaying the first recommended word, wherein the at least one letter is maintained in the second recommended word,

wherein the input word, the first recommended word and the second recommended word are different from each other, and

wherein the first manner is identified based on a touch for an input held within a first predetermined time range and the second manner is identified based on a touch for an input held within a second predetermined time range different than the first predetermined time range.

9. The electronic device of claim 8, wherein the at least one processor is further configured to:

obtain a predetermined delimiter received next to the input word;

in response to obtaining the predetermined delimiter, determine whether to disable a function of automatically recommending a word;

in response to identifying the first manner or the second manner, enable the function; and

in response to identifying the manner of the touch input as a third manner, disable the function and display the an input word including the at least one intact.

10. The electronic device of claim 9, wherein the third manner is identified based on the touch for an input held longer than the second predetermined time range.

11. The electronic device of claim 9, wherein the third manner is identified based on the touch for an input being made with a pressure greater than or equal to a predetermined value.

12. The electronic device of claim 9, wherein the third manner is identified based on the touch for an input being made with an area greater than or equal to a predetermined value.

13. The electronic device of claim 8, wherein the manner of the touch input includes at least one of a time for which a touch is held for an input, a touch pressure, a contact area, or a behavior of a gesture.

14. The electronic device of claim 8, wherein the at least one processor is further configured to control, based on a touch in a keypad area being held for a predetermined or more, the display to expand the touched keypad area or a perimeter of the touched keypad area with a predetermined value or more.

15. The electronic device of claim 8, wherein the display is further configured to display a keyboard including letter keys and special keys which are separated from at least one of the letter keys by a blank area.

16. A non-transitory computer readable storage medium recording a program for executing a method for processing a letter input by at least one processor in an electronic device, the method comprising:

when at least one letter is obtained, identifying a manner of a touch input for the at least one letter;

obtaining an input word including the at least one letter;

in response to identifying a first manner as the manner of the touch input, displaying a first recommended word similar to the input word, wherein the at least one letter is changed to a letter in the first recommended word; and

in response to identifying a second manner as the manner of the touch input, displaying a second recommended word similar to the input word without displaying the first recommended word, wherein the at least one letter is maintained in the second recommended word,

wherein the input word, the first recommended word and the second recommended word are different from each other, and

wherein the first manner is identified based on a touch for an input held within a first predetermined time range and the second manner is identified based on a touch for an input held within a second predetermined time range different than the first predetermined time range.
