Abstract

A character correcting method using an electronic device includes displaying a virtual keyboard that includes a plurality of character keys on a display device. A character corresponds to one of the plurality of character keys is outputted. A wrong character is determined when a delete key on the virtual keyboard is touched. Multiple candidate keys are determined according to a position of a character key that corresponds to the wrong character on the virtual keyboard. The candidate keys are displayed on a generated window. Once one of the candidate keys on the window is touched, the wrong character is replaced with a character that corresponds to the one of the candidate keys.

Claims

1. A character correcting method for an electronic device, the method comprising:

displaying a virtual keyboard on a display device of the electronic device, wherein the virtual keyboard comprises a plurality of character keys;

outputting, at the electronic device, a character corresponding to one of the plurality of character keys, according to touch signals generated when the one of the plurality of character keys is touched;

determining, at the electronic device, the outputted character to be a wrong character, when a delete key on the virtual keyboard is touched, wherein a character key that corresponds to the wrong character is defined to be a wrong character key;

determining, at the electronic device, a plurality of candidate keys according to a position of the wrong character key on the virtual keyboard;

generating, at the display device, a window and displaying the candidate keys on the window; and

replacing, at the display device, the wrong character with a character corresponding to one of the candidate keys touched on the window.

2. The method according to claim 1, wherein the candidate keys comprise all character keys located in a predetermined range around the position of the wrong character key on the virtual keyboard.

3. The method according to claim 1, wherein the candidate keys are displayed on the window according to touch areas of the candidate keys, wherein the touch areas are determined according to touch signals generated by the candidate keys when the user touches the wrong character key.

4. The method according to claim 1, wherein the candidate keys are displayed on the window according to a position of each of the candidate keys on the virtual keyboard.

5. The method according to claim 1, wherein a size of each of the candidate keys on the window is in direct proportion to a touch area corresponding to each of the candidate keys.

6. The method according to claim 1, further comprising:

generating a control key and displaying the control key on the window; and

closing the window and returning to the virtual keyboard when the control key is touched.

7. An electronic device comprising:

at least one processor;

a storage device being configured to store one or more programs that, when executed by the at least one processor, cause the at least one processor to;

display a virtual keyboard on a display device of the electronic device, wherein the virtual keyboard comprises a plurality of character keys;

output a character corresponding to one of the plurality of character keys, according to touch signals generated when the one of the plurality of character keys is touched;

determine the outputted character to be a wrong character, when a delete key on the virtual keyboard is touched, wherein a character key that corresponds to the wrong character is defined to be a wrong character key;

determine a plurality of candidate keys according to a position of the wrong character key on the virtual keyboard;

generate a window and display the candidate keys on the window; and

replace the wrong character with a character corresponding to one of the candidate keys touched on the window.

8. The electronic device according to claim 7, wherein the candidate keys comprise all character keys located in a predetermined range around the position of the wrong character key on the virtual keyboard.

9. The electronic device according to claim 7, wherein the candidate keys are displayed on the window according to touch areas of the candidate keys, wherein the touch areas are determined according to touch signals generated by the candidate keys when the user touches the wrong character key.

10. The electronic device according to claim 7, wherein the candidate keys are displayed on the window according to a position of each of the candidate keys on the virtual keyboard.

11. The electronic device according to claim 7, wherein a size of each of the candidate keys on the window is in direct proportion to a touch area corresponding to each of the candidate keys.

12. The electronic device according to claim 7, wherein the at least one processor is further caused to:

generate a control key and display the control key on the window; and

close the window and return to the virtual keyboard when the control key is touched.

13. A non-transitory storage medium having stored thereon instructions that, when executed by a processor of an electronic device, causes the processor to perform a character correcting method, wherein the method comprises:

displaying a virtual keyboard on a display device of the electronic device, wherein the virtual keyboard comprises a plurality of character keys;

outputting a character corresponding to one of the plurality of character keys, according to touch signals generated when the one of the plurality of character keys is touched;

determining the outputted character to be a wrong character, when a delete key on the virtual keyboard is touched, wherein a character key that corresponds to the wrong character is defined to be a wrong character key;

determining a plurality of candidate keys according to a position of the wrong character key on the virtual keyboard;

generating a window and displaying the candidate keys on the window; and

replacing the wrong character with a character corresponding to one of the candidate keys touched on the window.

14. The non-transitory storage medium according to claim 13, wherein the candidate keys comprise all character keys located in a predetermined range around the position of the wrong character key on the virtual keyboard.

15. The non-transitory storage medium according to claim 13, wherein the candidate keys are displayed on the window according to touch areas of the candidate keys, wherein the touch areas are determined according to touch signals generated by the candidate keys when the user touches the wrong character key.

16. The non-transitory storage medium according to claim 13, wherein the candidate keys are displayed on the window according to a position of each of the candidate keys on the virtual keyboard.

17. The non-transitory storage medium according to claim 13, wherein a size of each of the candidate keys on the window is in direct proportion to a touch area corresponding to each of the candidate keys.

18. The non-transitory storage medium according to claim 13, wherein the method further comprises:

generating a control key and displaying the control key on the window; and

closing the window and returning to the virtual keyboard when the control key is touched.
