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

2. The apparatus according to claim 1, wherein the area indicating existence of the plurality of objects is an area in which at least a part of the plurality of objects are displayed as overlapping each other.

3. The apparatus according to claim 1, wherein the display changing unit displays an arrangement of the plurality of objects.

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

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

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

an obtaining unit configured to obtain a position of each of a plurality of touch 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 grouped objects wherein at least a part of the grouped objects are overlapping each other; and

a display changing unit configured to, if 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 from a position where the plurality of grouped objects are displayed in a condition where at least a part of the group objects are overlapping each other, display an arrangement of the plurality of grouped objects on the touch screen.

7. The apparatus according to claim 6, wherein the display changing unit controls a position interval of the plurality of objects in the arrangement based on the positions of the plurality of touch points that have moved.

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

an obtaining unit configured to obtain a position of each of a plurality of touch 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 configured to, if 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 from positions of the plurality of objects displayed by the display unit, change locations of the plurality of objects.

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

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

a display step of displaying an area indicating existence of a plurality of objects on the touch screen; and

a display changing step of displaying, if 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 from the area indicating existence of the plurality of objects, the plurality of objects on the touch screen, whose existences are indicated by the area.

10. The method according to claim 9, wherein the area indicating existence of the plurality of objects is an area in which at least a part of the plurality of objects are displayed as overlapping each other.

11. The method according to claim 9, wherein the display changing step displays an arrangement of the plurality of objects.

12. The method according to claim 9, wherein the display changing step controls a position interval of the plurality of objects displayed on the touch screen based on the positions of the plurality of touch points that have moved.

13. The method according to claim 9, wherein the display changing step changes a front/rear overlapping relationship of the plurality of objects displayed on the touch screen.

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

an obtaining step of obtaining position of each of a plurality of touch 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 grouped objects wherein at least a part of the grouped objects are overlapping each other; and

a display changing step of displaying, if 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 from a position where the plurality of grouped objects are displayed in a condition where at least a part of the group objects are overlapping each other, an arrangement of the plurality of grouped objects on the touch screen.

15. The method according to claim 14, wherein the display changing step controls a position interval of the plurality of objects in the arrangement based on the positions of the plurality of touch points that have moved.

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

an obtaining step of obtaining position of each of a plurality of touch 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 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 from positions of the plurality of objects displayed by the display unit, locations of the plurality of objects.

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

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

a display step of displaying an area indicating existence of a plurality of objects on the touch screen; and

a display changing step of displaying, if 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 from the area indicating existence of the plurality of objects, the plurality of objects on the touch screen, whose existences are indicated by the area.
