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 display which detects a touch input, comprising:

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

a display control unit configured to cause the touch screen display to display a plurality of objects wherein at least a part of the plurality of objects are overlapping each other;

wherein the display control unit, in a case where it is detected that positions of the plurality of touch points obtained by the obtaining unit move in directions such that the plurality of touch points obtained by the obtaining unit become further away from each other where at least a part of the plurality of objects are overlapping each other, causes the touch screen display to change locations of the plurality of objects.

2. The apparatus according to claim 1, wherein each of the plurality of objects is an image data.

3. The apparatus according to claim 1, wherein the display control unit aligns each object in the plurality of objects equally spaced apart, based on the positions of the plurality of touch points that have moved.

4. The apparatus according to claim 1, wherein the display control unit controls a position interval of the plurality of objects displayed on the touch screen display based on the positions of the plurality of touch points that have moved.

5. The apparatus according to claim 1, wherein the display control unit changes a front/rear overlapping relationship of the plurality of objects displayed on the touch screen display.

15. The apparatus according to claim 1, wherein the display control unit is configured to rearrange the plurality of objects in the touch screen display such that the objects that overlap each other in different directions are rearranged to a state where the differences in directions is small.

16. The apparatus according to claim 15, wherein a state where the plurality of objects are overlapping each other in different directions is a state where a first angle between a first object and a second object is different from a second angle between the second object and a third object.

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

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

a display control unit configured to cause the touch screen display to display a plurality of objects wherein at least a part of the plurality of objects are overlapping each other,

wherein the display control unit, in a case where the relative distance between two touch points obtained by the obtaining unit is extending where at least a part of the plurality of objects are overlapping each other, causes the touch screen display to change locations of the plurality of objects.

7. The apparatus according to claim 6, wherein the plurality of objects are a plurality of image data.

8. The apparatus according to claim 6, wherein the display control unit causes the touch screen display to display an arrangement of the plurality of objects.

9. The apparatus according to claim 8, wherein the display control unit controls a position interval of the plurality of objects in the arrangement based on the relative distance between two touch points that have changed.

10. The apparatus according to claim 6, wherein the display control unit changes a front/rear overlapping relationship of the plurality of objects displayed on the touch screen display.

17. The apparatus according to claim 6, wherein the display control unit is configured to rearrange the plurality of objects in the touch screen display such that the objects that overlap each other in different directions are rearranged to a state where the differences in directions is small.

18. The apparatus according to claim 17, wherein a state where the plurality of objects are overlapping each other in different directions is a state where a first angle between a first object and a second object is different from a second angle between the second object and a third object.

11. A method of controlling an information processing apparatus, the information processing apparatus having a touch screen display which detects a touch input, the method comprising:

an obtaining step of obtaining positions of a plurality of touch points corresponding to a plurality of touch inputs existing at the same time on the touch screen display; and

a displaying step of causing the touch screen display to display a plurality of objects wherein at least a part of the plurality of objects are overlapping each other;

wherein the displaying step, in a case where it is detected that positions of the plurality of touch points obtained by the obtaining step move in directions such that the plurality of touch points obtained by the obtaining step become further away from each other where at least a part of the plurality of objects are overlapping each other, causes the touch screen display to change locations of the plurality of objects.

12. A method of controlling an information processing apparatus, the information processing apparatus having a touch screen display which detects a touch input, the method comprising:

an obtaining step of obtaining positions of a plurality of touch points corresponding to a plurality of touch inputs existing at the same time on the touch screen display; and

a displaying step of causing the touch screen display to display a plurality of objects wherein at least a part of the plurality of objects are overlapping each other,

wherein the displaying step, in a case where the relative distance between two touch points obtained by the obtaining step is extending where at least a part of the plurality of objects are overlapping each other, causes the touch screen display to change locations of the plurality of objects.

13. A non-transitory computer-readable storage medium including a program that, when executed by a computer, causes the computer to execute a method of controlling an information processing apparatus, the information processing apparatus having a touch screen display which detects a touch input, the method comprising:

an obtaining step of obtaining positions of a plurality of touch points corresponding to a plurality of touch inputs existing at the same time on the touch screen display; and

a displaying step of causing the touch screen display to display a plurality of objects wherein at least a part of the plurality of objects are overlapping each other;

wherein the displaying step, in a case where it is detected that positions of the plurality of touch points obtained by the obtaining step move in directions such that the plurality of touch points obtained by the obtaining step become further away from each other where at least a part of the plurality of objects are overlapping each other, causes the touch screen display to change locations of the plurality of objects.

14. A non-transitory computer-readable storage medium including a program that, when executed by a computer, causes the computer to execute a method of controlling an information processing apparatus, the information processing apparatus having a touch screen display which detects a touch input, the method comprising:

an obtaining step of obtaining positions of a plurality of touch points corresponding to a plurality of touch inputs existing at the same time on the touch screen display; and

a displaying step of causing the touch screen display to display a plurality of objects wherein at least a part of the plurality of objects are overlapping each other,

wherein the displaying step, in a case where the relative distance between two touch points obtained by the obtaining step is extending where at least a part of the plurality of objects are overlapping each other, causes the touch screen display to change locations of the plurality of objects.
