Abstract

A computing apparatus for recognizing a touch input is disclosed. In accordance with the present invention, one or more objects and a space including the one or more objects displayed on a display device may be easily controlled by converting a touch of a first finger group and a touch of a second finger group into a predetermined command.

Claims

1. A computing apparatus connected to a display device and a touch recognition device mounted on the display device, the apparatus comprising:

a memory, a program stored in the memory and a processor for executing the program, wherein the program comprises;

a first instruction for detecting a touch of a first finger group and a touch of a second finger group applied on the touch recognition device;

a second instruction for mapping the touch of the first finger group and the touch of the second finger group onto a first position information and a second position information of a screen displaying on the display device, respectively; and

a third instruction for converting the touch of the first finger group and the touch of the second finger group into a predetermined command based on the first position information and the second position information.

2. The computing apparatus in accordance with claim 1, wherein the display device displays on the screen a space comprising an area with objects including one or more objects and an area without objects other than the area with objects.

3. The computing apparatus in accordance with claim 2, wherein the second position information corresponds to the area with objects on the screen, and

the first position information corresponds to the area without objects on the screen.

4. The computing apparatus in accordance with claim 3, wherein the second instruction comprises a first sub-instruction for mapping the touch of the first finger group onto the first position information and a second sub-instruction for mapping the touch of the second finger group onto the second position information when the first position information is constant, and

the processor subjects the object corresponding to the second position information to the command converted by the third instruction.

5. The computing apparatus in accordance with claim 4, wherein the command comprises one of select, rotate, move, zoom in and zoom out.

6. The computing apparatus in accordance with claim 3, wherein the second instruction comprises a first sub-instruction for mapping the touch of the second finger group onto the second position information and a second sub-instruction for mapping the touch of the first finger group onto the first position information when the second position information is constant, and

the processor subjects the object corresponding to the second position information to the command converted by the third instruction.

7. The computing apparatus in accordance with claim 6, wherein the second sub-instruction and the third instruction are executed while the first sub-instruction is executed or after the first sub-instruction is executed.

8. The computing apparatus in accordance with claim 7, wherein the command comprises one of select, rotate, move, zoom in and zoom out.

9. The computing apparatus in accordance with claim 2, wherein the first position information and the second position information correspond to the area without objects on the screen.

10. The computing apparatus in accordance with claim 9, wherein the second instruction comprises a first sub-instruction for mapping the touch of the first finger group onto the first position information and a second sub-instruction for mapping the touch of the second finger group onto the second position information when the first position information is constant, and

the processor subjects the area with objects to the command converted by the third instruction based on the first position information.

11. The computing apparatus in accordance with claim 10, wherein the second sub-instruction and the third instruction are executed while the first sub-instruction is executed or after the first sub-instruction is executed.

12. The computing apparatus in accordance with claim 11, wherein the command comprises one of rotate, move, zoom in and zoom out.

13. The computing apparatus in accordance with claim 2, wherein one or more objects are displayed in perspective view.

14. The computing apparatus in accordance with claim 1, wherein the touches of the first finger group and the second finger group are applied on the touch recognition device by both hands of an user.

15. The computing apparatus in accordance with claim 1, wherein the touch recognition device is integrated into the display device.

16. A computer-readable medium having thereon a program carrying out a method for recognizing a touch input comprising:

detecting a touch of a first finger group and a touch of a second finger group applied on a touch recognition device;

mapping the touch of the first finger group and the touch of the second finger group onto a first position information and a second position information of a screen displayed on a display device, respectively; and

converting the touch of the first finger group and the touch of the second finger group into a predetermined command based on the first position information and the second position information.
