Method and device for inputting handwriting character

1. A method for inputting handwriting character, comprising:

adding a handwriting input on a touch screen, where the touch screen has a plurality of input areas;

detecting a position of an initial point of the handwriting input;

determining an input area for the handwriting input among the plurality of input areas of the touch screen based on the position of the initial point of the handwriting input;

determining an operation of the handwriting input based on the position of the initial point of the handwriting input and performing the determined operation, wherein the step of determining an operation of the handwriting input further comprises:

if the position of the initial point of the handwriting input does not fall on an existing character, determining whether the position of the initial point of the handwriting input falls between two existing characters; and

if it is determined that the position of the initial point of the handwriting input falls between the two existing characters, determining the operation of the handwriting input as inserting a character between the two existing characters; and

upon completion of the handwriting input, recognizing the input as a character and displaying the recognized character in the determined input area on the touch screen.

2. The method of claim 1 , wherein the step of determining an input area for the handwriting input among the plurality of input areas of the touch screen further comprises:

if the position of the initial point of the handwriting input falls in one of the plurality of input areas, determining the one of the plurality of input areas as the input area for the handwriting input.

3. The method of claim 1 , wherein the step of determining an operation of the handwriting input further comprises:

if the position of the initial point of the handwriting input falls on an existing character, determining the operation of the handwriting input as correcting the existing character.

4. The method of claim 3 ,

wherein correcting the existing character comprises: replacing a wrong stroke with a new stroke or adding a missing stroke onto the existing character without repeatedly inputting an existing and correct stroke of the existing character,

wherein the step of recognizing the input as a character and displaying the recognized character further comprises:

recognizing the input as the character by combining the input with the existing and correct stroke of the existing character; and

displaying the recognized character by replacing the existing character with the recognized character.

5. The method of claim 1 , wherein:

if it is determined that the position of the initial point of the handwriting input does not fall on the existing character and does not fall between the two existing characters, determining whether the position of the initial point of the handwriting input falls after an existing character; and

if it is determined that the position of the initial point of the handwriting input falls after the existing character, determining the operation of the handwriting input as continuing writing a character after the existing character.

6. The method of claim 5 , wherein:

if it is determined that the position of the initial point of the handwriting input does not fall on the existing character, does not fall between the two existing characters, and does not fall after the existing character, determining the operation of the handwriting input as writing a first character of a word or a sentence.

7. The method of claim 1 , wherein the step of recognizing the input comprises recognizing the input by only considering the character, without considering a word or a sentence containing the character.

8. The method of claim 1 , wherein the character is an alphanumeric character.

9. The method of claim 1 , wherein the character is an ideographic character.

10. An electronic device for inputting handwriting character, comprising:

a touch screen having a plurality of input areas;

a memory configured to store non-transitory computer-executable instructions;

a processor, coupled to the memory and the touch screen, configured to perform a set of functions including:

adding a handwriting input on the touch screen;

detecting a position of an initial point of the handwriting input;

determining an input area for the handwriting input among the plurality of input areas of the touch screen based on the position of the initial point of the handwriting input;

determining an operation of the handwriting input based on the position of the initial point of the handwriting input and performing the determined operation, wherein the processor is configured to perform the function of determining an operation of the handwriting input by:

if the position of the initial point of the handwriting input does not fall on an existing character, determining whether the position of the initial point of the handwriting input falls between two existing characters; and

if it is determined that the position of the initial point of the handwriting input falls between the two existing characters, determining the operation of the handwriting input as inserting a character between the two existing characters; and

upon completion of the handwriting input, recognizing the input as a character and displaying the recognized character in the determined input area on the touch screen.

11. The electronic device of claim 10 , wherein the processor is configured to perform the function of determining an input area for the handwriting input among the plurality of input areas of the touch screen by:

if the position of the initial point of the handwriting input falls in one of the plurality of input areas, determining the one of the plurality of input areas as the input area for the handwriting input.

12. The electronic device of claim 10 , wherein the processor is configured to perform the function of determining an operation of the handwriting input by:

if the position of the initial point of the handwriting input falls on an existing character, determining the operation of the handwriting input as correcting the existing character.

13. The electronic device of claim 12 ,

wherein the processor is configured to perform the function of correcting the existing character by replacing a wrong stroke with a new stroke or adding a missing stroke onto the existing character without repeatedly inputting an existing and correct stroke of the existing character,

wherein the processor is configured to perform the function of recognizing the input as a character and displaying the recognized character by:

recognizing the input as the character by combining the input with the existing and correct stroke of the existing character; and

displaying the recognized character by replacing the existing character with the recognized character.

14. The electronic device of claim 10 , wherein the processor is further configured to perform the functions of:

if it is determined that the position of the initial point of the handwriting input does not fall on the existing character and does not fall between the two existing characters, determining whether the position of the initial point of the handwriting input falls after an existing character; and

if it is determined that the position of the initial point of the handwriting input falls after the existing character, determining the operation of the handwriting input as continuing writing a character after the existing character.

15. The electronic device of claim 14 , wherein the processor is further configured to perform the function of:

if it is determined that the position of the initial point of the handwriting input does not fall on the existing character, does not fall between the two existing characters, and does not fall after the existing character, determining the operation of the handwriting input as writing a first character of a word or a sentence.

16. The electronic device of claim 10 , wherein the processor is configured to perform the function of recognizing the input by recognizing the input by only considering the character, without considering a word or a sentence containing the character.

17. The electronic device of claim 10 , wherein the character is an alphanumeric character.

18. The electronic device of claim 10 , wherein the character is an ideographic character.
