Abstract

An electronic device includes a touch position receiving unit which receives from a touch panel, touch position information indicating each of touch positions of a first object and at least one of second objects with respect to the touch panel for each object, the second object being different from the first object, a change type setting unit which calculates a movement direction of each of the first object and the second object based on the touch position information, and determines a change type of a display of the touch panel based on the movement direction, and a change amount setting unit which recognizes the number of the second objects based on the touch position information, and determines a change amount of the display based on the number.

Claims

1. An electronic device comprising:

a touch position receiving unit which receives, from a touch panel, touch position information indicating each of touch positions of a first object and at least one of second objects with respect to the touch panel for each object, the second object being different from the first object;

a change type setting unit which calculates a movement direction of each of the first object and the second object based on the touch position information, and determines a change type of a display of the touch panel based on the movement direction; and

a change amount setting unit which recognizes the number of the second objects based on the touch position information, and determines a change amount of the display based on the number.

2. The electronic device according to claim 1,

wherein the change type setting unit determines the change type based on the change in a relative position of the second object with respect to the first object, the change in the relative position being calculated based on the touch position information of the first object and the touch position information of the second object.

3. The electronic device according to claim 2,

wherein the number of the first object is one, the number of the second objects is plural, and a plurality of the second objects move in the same direction each other.

4. The electronic device according to claim 2,

wherein based on a change amount of the relative position between the first object and the second object, the change amount setting unit further determines the change amount.

5. The electronic device according to claim 2,

wherein the change type setting unit enlarges and displays a screen when a distance from the first object to the second object has been increased.

6. The electronic device according to claim 5,

wherein the change amount setting unit increases an enlargement factor of the screen as the number of the second objects is increased.

7. The electronic device according to claim 2,

wherein the change type setting unit shrinks and displays the screen when the distance from the first object to the second object has been decreased.

8. The electronic device according to claim 7,

wherein the change amount setting unit increases an shrink factor of the screen as the number of the second objects is increased.

9. The electronic device according to claim 1,

wherein the change amount setting unit causes the screen to be scrolled in a movement direction of the second object.

10. The electronic device according to claim 9,

wherein the change amount setting unit increases a scroll amount of the screen as the number of the second objects is increased.

11. The electronic device according to claim 1,

wherein a plurality of images, orders of which are predetermined, are displayed in a set order on the touch panel, and

wherein the change type setting unit switches an image that is being displayed to a previous- or next-image of the image.

12. The electronic device according to claim 11,

wherein the change amount setting unit increases a return number or a progress number of the image as an amount of the touch position information is increased.

13. The electronic device according to claim 1,

wherein the electronic device stores data in a folder format with a plurality of hierarchical structures,

wherein the touch panel displays a first folder positioned in a first hierarchy,

wherein the change type setting unit changes the hierarchy of the folder to be displayed on the screen, and

wherein the change amount setting unit determines the change amount of the hierarchy based on the number of the second objects.

14. The electronic device according to claim 1,

wherein the change amount setting unit maximizes the change amount when the number of the second objects is equal to or larger than a predefined number.

15. The electronic device according to claim 1,

wherein in a case where the number of the second objects is changed after the change amount is determined, the change amount setting unit changes the change amount using the changed number of the second objects.

16. The electronic device according to claim 1, further comprising:

a control setting unit which determines control over the electronic device based on the number of the second objects, when it is determined that the first object moves in a direction different from the second object.

17. The electronic device according to claim 1,

wherein the control setting unit determines a zoom ratio of a screen to be displayed on the touch panel based on the number of the second object, and changes the zoom ratio of the screen based on a change in a relative position of the first object and the second object.

18. The electronic device according to claim 1,

wherein the control setting unit determines a zoom ratio of a screen to be displayed on the touch panel based on the number of the second object, and determines a movement direction of the screen based on a movement direction of the second object.

19. The electronic device according to claim 1,

wherein the touch panel is provided in the electronic device,

wherein the electronic device has a volatile memory, a non-volatile memory, or a hard disk, and

wherein when the movement direction of the second object satisfies a condition, the control setting unit saves data and determines where to store the data in the volatile memory, the non-volatile memory, or the hard disk, in response to the number of the second objects.

20. The electronic device according to claim 1,

wherein the touch panel is provided in the electronic device,

wherein the electronic device displays a trash folder and an icon indicating data on the touch panel,

wherein the control setting unit moves the data to the trash folder when the first object moves to the trash folder while selecting the icon, and

wherein the control setting unit erases the data when the first object and at least one of the second objects moves to the trash folder while selecting the icon.

21. The electronic device according to claim 1, further comprising the touch panel.

22. A control setting method of a display of a touch panel which is implemented by a computer comprising:

receiving, from a touch panel, touch position information indicating each of touch positions of a first object and at least one of the second objects with respect to the touch panel for each object, the second object being different from the first object;

calculating a movement direction of each of the first object and the second object based on the touch position information, and determining a change type of a display of the touch panel based on the movement direction; and

recognizing the number of the second objects based on the touch position information, and determining a change amount of the display based on the number.

23. A non-transitory computer-readable storage medium including a program which causes a computer to function as an electronic device which controls a display of a touch panel, the program causing the computer to execute:

receiving, from a touch panel, touch position information indicating each of touch positions of a first object and at least one of second objects with respect to the touch panel for each object, the second object being different from the first object;

calculating a movement direction of each of the first object and the second object based on the touch position information, and determining a change type of a display of the touch panel based on the movement direction; and

recognizing the number of the second objects based on the touch position information, and determining a change amount of the display based on the number.
