Abstract

A device and method are provided for increasing touch screen response.

Claims

1. A touch screen response method, comprising:

acquiring a touch;

determining a touch region based on a location of the touch;

acquiring option buttons, each having a respective overlap region with the touch region;

calculating a possibility of being selected of each option button by using a first function including a respective calculation coefficient for each option button, an area of the respective overlap region for each option button, and a respective button area corresponding to each option button; and

selecting an option button having a maximum possibility of being selected,

wherein the respective calculation coefficient for each button option corresponds to at least one of an importance of the corresponding button and a use frequency of the corresponding button.

2. The touch screen response method according to claim 1, wherein the method further comprises:

changing and storing the calculation coefficient of the button having the maximum possibility of being selected.

3. The touch screen response method according to claim 1, wherein the method further comprises:

selecting no button when a plurality of option buttons having the maximum possibility of being selected exists or when a difference between a possibility of being selected of one or more option buttons is within a preset range.

4. The touch screen response method according to claim 1, wherein the method further comprises:

re-calculating the possibility of being selected by using a second function for calculating a possibility of being selected when a plurality of buttons having the maximum possibility of being selected exists or when a difference between a possibility of being selected of one or more option buttons is within a preset range.

5. The touch screen response method according to claim 1, wherein the method further comprises:

determining whether only one button exists in the touch region, and selecting the button if yes.

6. The touch screen response method according to claim 1, wherein the calculation coefficient for each option button comprises an area calculation coefficient;

and the first function comprises K_i×

S_i/G_i, where Ki is the area calculation coefficient for option button i, Si is the area of the respective overlap region for option button i, and Gi is the respective button area for option button i.

7. The touch screen response method according to claim 6, comprising:

selecting buttons in a window at an uppermost layer as option buttons among all windows where buttons each having an overlap portion with the touch region are located.

8. The touch screen response method according to claim 6, wherein the method further comprises:

changing and storing the area calculation coefficient of the button having the maximum possibility of being selected.

9. The touch screen response method according to claim 8, wherein changing the area calculation coefficient comprises:

10. The touch screen response method according to claim 1, wherein

determining the touch region comprises:

determining a first touch region according to the touch;

determining whether the determined touch region satisfies a preset condition;

in response to the first touch region not satisfying the first preset condition, determining a second touch region;

determining whether the second touch region satisfies the preset condition;

continuing to determine a touch region until the preset condition is satisfied; and

selecting the touch region that satisfies the preset condition as the touch region.

11. The touch screen response method according to claim 10, wherein the method further comprises:

changing and storing the method of generating the touch region, and the changed method of generating the touch region is used as a method of generating a touch region for a next touch.

12. A touch screen response device, comprising:

a touch acquisition module, configured to acquire a touch and generate a touch region based on a location of the touch;

an option button acquisition module, configured to acquire option buttons, each having a respective overlap region with the touch region;

a possibility-of-being-selected calculation module, configured to calculate a possibility of being selected of each option button by using a first function including a respective calculation coefficient for each option button, an area of the respective overlap region for each option button, and a respective button area corresponding to each option button; and

a button selection module, configured to select a button of the option buttons having a maximum possibility of being selected,

wherein said respective calculation coefficient corresponds to at least one of an importance of the corresponding button and a use frequency of the corresponding button.

13. The touch screen response device according to claim 12, further comprising:

a calculation coefficient changing module, configured to change and store the calculation coefficient of the button having the maximum possibility of being selected.

14. The touch screen response device according to claim 12, wherein

the possibility-of-being-selected calculation module is further configured to re-calculate a possibility of being selected by using a second function for calculating a possibility of being selected when a plurality of buttons having the maximum possibility of being selected exists or a difference between a possibility of being selected of one or more option buttons is within a preset range.

15. The touch screen response device according to claim 12, wherein

the calculation coefficient for each button comprises an area calculation coefficient;

and

the possibility-of-being-selected calculation module is configured to calculate a function value of the first function using K_i×

S_i/G_i, where Ki is the area calculation coefficient for option button i, Si is the area of the respective overlap region for option button i, and Gi is the respective button area for option button i.

16. The touch screen response device according to claim 15, wherein

for the option buttons, buttons in a window at an uppermost layer are selected as option buttons among all windows where buttons each having an overlap portion with the touch region are located.

17. The touch screen response device according to claim 15, further comprising:

an area calculation coefficient changing module, configured to change and store the area calculation coefficient of the button having the maximum possibility of being selected.

18. A touch screen system, comprising:

a main control unit configured to perform data calculation and processing;

a touch screen coupled with a touch screen control unit, wherein the touch screen and touch screen control unit are configured to provide a user interface; and

a storage configured to store an operation system, software programs, and data;

wherein the main control unit is configured to perform operations to determine a touch region according to user interaction with the touch screen, determine option buttons, each having a respective overlap region with the touch region, calculate a possibility of being selected of each option button by using a first function including a calculation coefficient corresponding to each option button, an area of the respective overlap region for each option button, and a respective button area corresponding to each option button, and select a button having a maximum possibility of being selected,

wherein the respective calculation coefficient for each button corresponds to at least one of an importance of the corresponding button and a use frequency of the corresponding button.
