Abstract

A control method using a touch shield to be performed by a touch sensing display, and an electronic apparatus are provided. The control method using the touch shield may include determining a touch area of a touched point in a normal state, switching to a touch shield state when the touch area is greater than or equal to a threshold value, and executing an instruction in response to a movement of the touched point in the touch shield state.

Claims

1. A control method using a touch shield, the method performed by a touch sensing display, the method comprising:

determining a touch area of a touched point in a normal state;

switching to a touch shield state when the touch area is greater than or equal to a threshold value; and

executing an instruction in response to a movement of the touched point in the touch shield state.

2. The method of claim 1, wherein the switching comprises:

switching to an intermediate state when the touch area is greater than or equal to the threshold value; and

switching to the touch shield state when the touched point is maintained for a threshold time in the intermediate state.

3. The method of claim 2, wherein the switching to the touch shield state when the touched point is maintained for the threshold time in the intermediate state comprises switching to the touch shield state when the touch area is maintained to be greater than or equal to the threshold value for the threshold time in the intermediate state.

4. The method of claim 2, wherein the switching to the touch shield state when the touched point is maintained for the threshold time in the intermediate state comprises generating a touch shield widget.

5. The method of claim 4, wherein the generating comprises providing an animation to generate the touch shield widget.

6. The method of claim 5, wherein the providing comprises providing the animation around the touched point.

7. The method of claim 2, further comprising:

switching to the normal state when the touched point is released in the intermediate state.

8. The method of claim 2, further comprising:

switching to the normal state when the touched point is moved in the intermediate state.

9. The method of claim 2, further comprising:

switching to the normal state when the touched point is out of a touch shield area in the intermediate state.

10. The method of claim 1, further comprising:

switching to the normal state when the touched point is released in the touch shield state.

11. The method of claim 4, wherein the executing comprises executing an instruction corresponding to upper, lower, left, and right directions respectively, when the touched point is moved in one of the upper, lower, left, and right directions, on the touch shield widget.

12. The method of claim 4, wherein:

the touch shield widget comprises a marking menu, and

the executing comprises executing an instruction corresponding to a predetermined menu selection when the touched point is moved to the predetermined menu selection of the marking menu.

13. The method of claim 4, wherein the executing comprises executing an instruction corresponding to a pattern when the touched point is moved along the pattern on the touch shield widget.

14. An electronic apparatus controlled using a touch shield, the apparatus comprising:

a touch sensing display;

a processing apparatus; and

a computer storage medium comprising instructions for controlling the processing apparatus to perform operations during execution performed by the processing apparatus,

wherein the operations comprise;

determining a touch area of a touched point in a normal state;

switching to a touch shield state when the touch area is greater than or equal to a threshold value; and

executing an instruction in response to a movement of the touched point in the touch shield state.

15. The apparatus of claim 14, wherein the switching comprises:

switching to an intermediate state when the touch area is greater than or equal to the threshold value;

switching to the touch shield state when the touch area is maintained to be greater than or equal to the threshold value for a threshold time in the intermediate state; and

generating a touch shield widget in the touch shield state.

16. The apparatus of claim 15, wherein the operations further comprise:

switching to the normal state when the touched point is released, moved, or out of a touch shield area, in the intermediate state.

17. The apparatus of claim 14, wherein the operations further comprise:

switching to the normal state when the touched point is released in the touch shield state.

18. The apparatus of claim 15, wherein the executing comprises executing an instruction corresponding to upper, lower, left, and right directions respectively, when the touched point is moved in one of the upper, lower, left, and right directions, on the touch shield widget.

19. The apparatus of claim 15, wherein:

the touch shield widget comprises a marking menu, and

the executing comprises executing an instruction corresponding to a predetermined menu selection when the touched point is moved to the predetermined menu selection of the marking menu.

20. The apparatus of claim 15, wherein the executing comprises executing an instruction corresponding to a pattern when the touched point is moved along the pattern on the touch shield widget.
