Abstract

An information processing apparatus comprising a touch screen which detects a touch input by a user detects the position and pressure of each of a plurality of pressed points corresponding to a plurality of touch inputs existing at the same time on a touch screen. Then, the front/rear overlap relationship of the plurality of objects displayed on the touch screen is changed based on the difference in pressure between the detected plurality of pressed points.

Claims

1. An information processing apparatus having a touch screen which detects a touch input, comprising:

an obtaining unit configured to obtain position of each of a plurality of pressed points corresponding to a plurality of touch inputs existing at the same time on the touch screen;

a display unit configured to display a plurality of objects on the touch screen; and

a display changing unit configure to, if a movement of positions of the plurality of pressed points from positions of the plurality of objects displayed by the display unit is detected, change locations of the plurality of objects based on the movement.

2. The apparatus according to claim 1, wherein the display changing unit changes a display such that the plurality of objects are aligned.

3. The apparatus according to claim 1, wherein the display changing unit changes a display interval of the plurality of objects.

4. The apparatus according to claim 1, wherein the display unit displays the plurality of objects overlapping each other, and the display changing unit changes a display of the plurality of objects such that the plurality of objects spread.

5. The apparatus according to claim 1, wherein the display changing unit changes front/rear overlap relationship o the plurality of objects.

6. The apparatus according to claim 1, wherein the display changing unit detects, as the movement, that positions of the plurality of pressed points move such that they become further away from each other.

7. The apparatus according to claim 1, wherein the obtaining unit further obtains pressure of each of the plurality of pressed points.

8. The apparatus according to claim 7, wherein the display changing unit changes display of the plurality of objects based on difference in pressure obtained by the obtaining unit between the plurality of pressed points.

9. An information processing apparatus having a touch screen which detects a touch input, comprising:

an obtaining unit configured to obtain pressure of each of a plurality of pressed points corresponding to a plurality of touch inputs existing at the same time on the touch screen; and

a generation unit configured to generate an operation instruction based on pressure of the plurality of pressed points.

10. The apparatus according to claim 9, wherein

the obtaining unit further obtains a relationship between pressures of the plurality of pressed points, and

the generation unit generates operation instruction based on the relationship of the pressure.

11. The apparatus according to claim 9, wherein

the obtaining unit further obtains movement of the plurality of pressed points, and

the generation unit generates operation instruction based on pressure of the plurality of pressed points and the movement.

12. The apparatus according to claim 9, further comprising a display control unit configured to perform display control for one or a plurality of objects displayed on the touch screen based on the pressure of the plurality of pressed points, which have been obtained by the obtaining unit.

13. The apparatus according to claim 12, wherein the display control unit aligns the plurality of objects based on pressure of the plurality of pressed points.

14. The apparatus according to claim 12, wherein the plurality of object have a front/rear overlap relationship, and the display control unit changes the front/rear overlap relationship of the plurality of objects based on the pressure.

16. The apparatus according to claim 13, wherein the obtaining unit further obtains location of a plurality of pressed points, and the display control unit displays an object at a position corresponding to the location, which has a size corresponding to the pressure.

15. An information processing apparatus having a touch screen which detects a touch input, comprising:

an obtaining unit configured to obtain pressure of each of a plurality of pressed points corresponding to a plurality of touch inputs existing at the same time on the touch screen;

a display control unit configured to control displaying, on the touch screen, a representation corresponding to the pressure obtained by the obtaining unit, such that a user can recognize pressure of the plurality of pressed points.

17. A control method of an information processing apparatus having a touch screen which detects a touch input by a user, comprising:

an obtaining step of obtaining position of each of a plurality of pressed points corresponding to a plurality of touch inputs existing at the same time on the touch screen;

a display step of displaying a plurality of objects on the touch screen; and

a display changing step of changing, if positions of the plurality of pressed points obtained in the obtaining step move from positions of the plurality of objects displayed in the display step, locations of the plurality of objects based on the movement.

18. A control method of an information processing apparatus having a touch screen which detects a touch input, comprising:

an obtaining step of obtaining pressure of each of a plurality of pressed points corresponding to a plurality of touch inputs existing at the same time on the touch screen;

a generation step of generating an operation instruction based on pressure of the plurality of pressed points.

19. A control method of an information processing apparatus having a touch screen which detects a touch input, comprising:

an obtaining step of obtaining pressure of each of a plurality of pressed points corresponding to a plurality of touch inputs existing at the same time on the touch screen;

a display control step of controlling to display, on the touch screen, a representation corresponding to the pressure obtained in the obtaining step, such that a user can recognize pressure of the plurality of pressed points.

20. A non-transitory computer readable storage medium storing a program for causing a computer to execute a method of an information processing apparatus having a touch screen which detects a touch input by a user, the method comprising:

an obtaining step of obtaining position of each of a plurality of pressed points corresponding to a plurality of touch inputs existing at the same time on the touch screen;

a display step of displaying a plurality of objects on the touch screen; and

a display changing step of changing, if positions of the plurality of pressed points obtained in the obtaining step move from positions of the plurality of objects displayed in the display step, locations of the plurality of objects based on the movement.

21. A non-transitory computer readable storage medium storing a program for causing a computer to execute a method of an information processing apparatus having a touch screen which detects a touch input, the method comprising:

an obtaining step of obtaining pressure of each of a plurality of pressed points corresponding to a plurality of touch inputs existing at the same time on the touch screen;

a generation step of generating an operation instruction based on pressure of the plurality of pressed points.

22. A non-transitory computer readable storage medium storing a program for causing a computer to execute a method of an information processing apparatus having a touch screen which detects a touch input, the method comprising:

an obtaining step of obtaining pressure of each of a plurality of pressed points corresponding to a plurality of touch inputs existing at the same time on the touch screen;
