Abstract

A method for automatic learning of software keyboard input characteristics includes the following steps. (a) An input is received. (b) Whether the input is a normal key input is determined. (c) The input value of the input is stored when the input is determined to be the normal key input. (d) Step (a)-(c) are repeated until (N+1) input values are stored, wherein N is a positive integer. (e) When there are (N+1) inputs stored, the input characteristics of the first input in the (N+1) inputs are determined according to the first stored input value in the stored (N+1) input values. A computer program product using the method and a system for automatic learning of software keyboard input characteristics are also disclosed herein.

Claims

1. A method for automatic learning of software keyboard input characteristics comprising the following steps:

(a) receiving an input;

(b) determining whether the input is a normal key input;

(c) storing the input value of the input when the input is determined to be the normal key input, wherein the input value of the input comprises the key value and the touch coordinate of the input;

(d) repeating step (a)-(c) until (N+1) input values are stored, wherein N is a positive integer;

(e) determining, according to the first stored input value in the stored (N+1) input values, the input characteristics of the first input in the (N+1) inputs when there are (N+1) inputs stored by determining the touch coordinate of the first input corresponding to the key value of the first input; and

(f) removing the first stored input value in the stored (N+1) input values.

2. The method of claim 1, further comprising the following step:

determining whether the input is a removing function; and

removing a stored input value when the input is determined to be the removing function.

3. The method of claim 2, wherein the removed input value is the last stored input value among the stored input values.

4. The method of claim 1, wherein the input characteristics of the first input in the (N+1) inputs comprise a coordinate shift direction and a coordinate shift amount.

5. The method of claim 1, wherein the normal key input is a character.

6. The method of claim 5, wherein the character is an alphabet, number or punctuation.

7. A system for automatic learning of software keyboard input characteristics comprising:

a receiving module for receiving an input;

a storage unit for storing the input value of the input;

an input determining module for determining whether the input is a normal key input;

a placing module for placing the input value of the input into the storage unit when the input determining module determines the input to be the normal key input, wherein the input value of the input comprises the key value and the touch coordinate of the input;

a characteristics determining system for determining, according to the first stored input value in the stored (N+1) input values, the input characteristics of the first input in the (N+1) inputs when there are already (N+1) input values stored in the storage unit by determining the touch coordinate of the first input corresponding to the key value of the first input, wherein N is a positive number; and

a first removing module for removing the first stored input value in the stored (N+1) input values after the input characteristics of the first input in the (N+1) inputs are determined.

8. The system of claim 7, wherein the input determining module comprises a removing function determining module for determining whether the input is a removing function.

9. The system of claim 8, wherein the placing module comprises a second removing module for removing an input value stored in the storage unit when the removing function determining module determines the input to be the removing function.

10. The system of claim 9, wherein the second removing module removes the last stored input value among the stored input values in the storage unit when removing the input value stored in the storage unit.

11. The system of claim 7, wherein the input characteristics of the first input in the (N+1) inputs comprise a coordinate shift direction and a coordinate shift amount.

12. The system of claim 7, wherein the normal key input is a character.

13. The system of claim 12, wherein the character is an alphabet, number or punctuation.

14. The system of claim 7, wherein the storage unit stores the input value of the input with a data structure.

15. The system of claim 14, wherein the data structure is a circular queue.

16. A computer storage medium storing program codes for executing the following steps:

(a) receiving an input;

(b) determining whether the input is a normal key input;

(c) storing the input value of the input when the input is determined to be the normal key input, wherein the input value of the input comprises the key value and the touch coordinate of the input;

(d) repeating step (a)-(c) until (N+1) input values are stored, wherein N is a positive integer;

(e) determining, according to the first stored input value in the stored (N+1) input values, the input characteristics of the first input in the (N+1) inputs when there are (N+1) inputs stored by determining the touch coordinate of the first input corresponding to the key value of the first input; and

(f) removing the first stored input value in the stored (N+1) input values.

17. The computer storage medium of claim 16, further comprising the following step:

determining whether the input is a removing function; and

removing a stored input value when the input is determined to be the removing function.

18. The computer storage medium of claim 17, wherein the removed input value is the last stored input value among the stored input values.

19. The computer storage medium of claim 16, wherein the input characteristics of the first input in the (N+1) inputs comprise a coordinate shift direction and a coordinate shift amount.

20. The computer storage medium of claim 16, wherein the normal key input is a character.

21. computer storage medium of claim 20, wherein the character is an alphabet, number or punctuation.
