Abstract

A method and system for revising user input position. The method for revising user input position includes, detecting input position of a user, revising the input position of the user based on a predefined revising model, to obtain an accurate position, where, a wrong input position of the user is at least analyzed in advance to obtain the revising model and in response to obtaining the accurate position, triggering an application corresponding to the accurate position. With the technology for automatically revising the input position of the user on the touch screen provided by the invention, it is possible to help the user more conveniently locate the needed content, so as to save the time of the user and improve the user experience.

Claims

1. A method for revising user input position, the method comprising the steps of:

detecting input position of a user;

revising the input position of the user based on a predefined revising model, to obtain an accurate position, wherein, a wrong input position of the user is at least analyzed in advance to obtain said revising model; and

in response to obtaining the accurate position, triggering an application corresponding to the accurate position.

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

obtaining said revising model by analyzing a correct input position of the user in advance.

3. The method according to claim 1, wherein, said at least analyzing wrong input positions of the user in advance to obtain said revising model includes:

obtaining the wrong input position of the user;

based on an association between the wrong input position of the user and the accurate position, forming a sample set; and

based on said sample set, forming said revising model.

4. The method according to claim 3, wherein said obtaining the wrong input position of the user includes:

obtaining an input position of the user; and

in response to obtaining a back action and an action for redetermining the accurate position of the user, determining the input position of the user as a wrong input position.

5. The method according to claim 2, wherein, said obtaining said revising model by analyzing a correct input position of the user in advance includes:

obtaining the correct input position of the user;

based on an association between the correct input position of the user and the accurate position, forming a sample set; and

based on said sample set, forming said revising model.

6. The method according to claim 3, wherein, said revising model is formed based on the sample set, and according to one of the Mathematical Expectation Model and the Mean Value Model.

7. The method according to claim 3, further comprising the step of:

recording an input path of the user.

8. The method according to claim 1, wherein, said input position is the input position of the user on a touch screen.

9. A system for revising user input position, comprising:

a detecting unit, configured to detect input position of a user;

a revising unit, configured to revise the input position of the user based on a predefined revising model, to obtain an accurate position, wherein, a wrong input position of the user is at least analyzed in advance by an analyzing unit to obtain said revising model; and

a triggering unit, be configured to, in response to obtaining the accurate position, trigger an application corresponding to the accurate position.

10. The system according to claim 9, wherein, said analyzing unit is further configured to obtain said revising model by analyzing a correct input position of the user in advance.

11. The system according to claim 9, wherein, said analyzing unit includes:

a wrong position obtaining unit, configured to obtain the wrong input position of the user;

a sample set forming unit, configured to, based on an association between the wrong input position of the user and the accurate position, form a sample set; and

a revising model forming unit, configured to, based on said sample set, form said revising model.

12. The system according to claim 10, wherein said wrong position obtaining unit includes:

an user input position obtaining unit, configured to obtain an input position of the user; and

a wrong input position determining unit, configured to, in response to obtaining a back action and an action for redetermining the accurate position of the user, determine the input position of the user as a wrong input position.

13. The system according to claim 9, wherein, said analyzing unit further includes:

a user correct input position obtaining unit, configured to obtain the correct input position of the user;

a sample set forming unit, configured to, based on an association between the correct input position of the user and the accurate position, form a sample set; and

a revising model forming unit, configured to, based on said sample set, form said revising model.

14. The system according to claim 10, wherein, said revising model is formed based on the sample set, and according to one of the Mathematical Expectation Model and the Mean Value Model.

15. The system according to claim 10, further comprising:

a unit for recording an input path of the user.

16. The system according to claim 9, wherein, said system has a touch screen, and said input position is the input position of the user on the touch screen.

17. A non-transitory computer readable storage medium tangibly embodying a computer readable program code having computer readable instructions which, when implemented, cause a computer to carry out the steps of a method comprising:

detecting input position of a user;

revising the input position of the user based on a predefined revising model, to obtain an accurate position, wherein, a wrong input position of the user is at least analyzed in advance to obtain said revising model; and

in response to obtaining the accurate position, triggering an application corresponding to the accurate position.
