Abstract

Information processing device includes display unit that displays operation object; tactile contact detection unit that detects a plurality of push-down points; and control unit that performs first operation assessment for detecting whether or not outer peripheral distance of first area formed by connecting adjacent push-down points among a plurality of push-down points detected by tactile contact detection unit decreases over time to predetermined value or less, and that performs second operation assessment for detecting whether or not the outer peripheral distance of second area formed by connecting adjacent push-down points among a plurality of push-down points detected by tactile contact detection unit increases over time to predetermined value or more. Control unit puts operation object in selected state when there is overlapping part between operation object and first area after first operation assessment, and performs first operation corresponding to place where second operation assessment has been performed on operation object.

Claims

1. An information processing device, comprising:

a display unit that displays a device'"'"'s operation object;

a tactile contact detection unit that detects a plurality of push-down points; and

a control unit that;

puts said device'"'"'s operation object in a selected state when there is an overlapping part between said device'"'"'s operation object and an area formed by connecting adjacent push-down points among said plurality of push-down points detected by said tactile contact detection unit when a user'"'"'s pinch operation is detected;

performs a user'"'"'s operation assessment for detecting a user'"'"'s release operation;

determines whether a number of push-down points when said user'"'"'s release operation is detected and a number of push-down points when said device'"'"'s operation object is put in the selected state are equal;

performs a first device'"'"'s operation in a case where said number of push-down points when said user'"'"'s release operation is detected and said number of push-down points when said device'"'"'s operation object is put in the selected state are equal; and

performs a second device'"'"'s operation in a case where said number of push-down points when said user'"'"'s release operation is detected and said number of push-down points when said device'"'"'s operation object is put in the selected state are different.

2. The information processing device according to claim 1, wherein said display unit changes a color of said device'"'"'s operation object when said device'"'"'s operation object is in said selected state.

3. The information processing device according to claim 1, wherein said control unit cancels said selected state according to a predetermined condition.

4. The information processing device according to claim 1, wherein said control unit performs said first device'"'"'s operation on a plurality of said device'"'"'s operation objects overlapping said area.

5. The information processing device according to claim 1, wherein said first device'"'"'s operation is moving said device'"'"'s operation object to a place where said user'"'"'s operation assessment has been performed.

6. The information processing device according to claim 1, wherein said control unit determines a start-up mode of a software program installed in advance by starting said software program in said selected state.

7. The information processing device according to claim 1, wherein said control unit:

performs a third device'"'"'s operation when there is no overlapping part between said device'"'"'s operation object and said area; and

performs a fourth device'"'"'s operation corresponding to said third device'"'"'s operation when said user'"'"'s operation assessment is performed.

8. The information processing device according to claim 1, wherein the determination of movement of push-down point includes determination that the push-down points spread outward.

9. A control method for an information processing device comprising:

a display unit that displays a device'"'"'s operation object; and

a tactile contact detection unit that detects a plurality of push-down points, said control method including;

putting said device'"'"'s operation object in a selected state when there is an overlapping part between said device'"'"'s operation object and an area formed by connecting adjacent push-down points among said plurality of push-down points detected by said tactile contact detection unit when a user'"'"'s pinch operation is detected;

performing a user'"'"'s operation assessment that detects a user'"'"'s release operation;

determining whether a number of push-down points when said user'"'"'s release operation is detected and a number of push-down points when said device'"'"'s operation object is put in the selected state are equal;

performing a first device'"'"'s operation in a case where said number of push-down points when said user'"'"'s release operation is detected and said number of push-down points when said device'"'"'s operation object is put in the selected state are equal; and

performing a second device'"'"'s operation in a case where said number of push-down points when said user'"'"'s release operation is detected and said number of push-down points when said device'"'"'s operation object is put in the selected state are different.

10. The control method for an information processing device according to claim 9, further including having the display unit change a color of the device'"'"'s operation object when the device'"'"'s operation object is selected.

11. The control method for an information processing device according to claim 9, further including canceling the selected state according to a predetermined condition.

12. The control method for an information processing device according to claim 9, wherein a plurality of the device'"'"'s operation objects overlapping the area are selected in the step of selecting the device'"'"'s operation objects.

13. The control method for an information processing device according to claim 9, wherein the first device'"'"'s operation is moving the device'"'"'s operation object to a place where the user'"'"'s operation assessment step has been performed.

14. The control method for an information processing device according to claim 9, further including determining a start-up mode of a software program installed in advance by starting the software program in a state in which the device'"'"'s operation object is selected.

15. The control method for an information processing device according to claim 9, further including:

performing a third device'"'"'s operation when there is no overlapping part between the device'"'"'s operation object and the area, and

performing a fourth device'"'"'s operation corresponding to the third device'"'"'s operation when the user'"'"'s operation assessment is performed.

16. A computer readable non-transitory medium storing a program executed by a computer that includes an information processing device comprising:

a display unit that displays a device'"'"'s operation object; and

a tactile contact detection unit that detects a plurality of push-down points, said program having said computer execute;

putting said device'"'"'s operation object in a selected state when there is an overlapping part between said device'"'"'s operation object and an area formed by connecting adjacent push-down points among said plurality of push-down points detected by said tactile contact detection unit when a user'"'"'s pinch operation is detected;

performing a user'"'"'s operation assessment that detects a user'"'"'s release operation;

determining whether a number of push-down points when said user'"'"'s release operation is detected and a number of push-down points which are detected when said device'"'"'s operation object is put in the selected state are equal;

performing a first device'"'"'s operation in a case where said number of push-down points when said user'"'"'s release operation is detected and said number of push-down points when said device'"'"'s operation object is put in the selected state are equal; and

performing a second device'"'"'s operation in a case where said number of push-down points when said user'"'"'s release operation is detected and said number of push-down points when said device'"'"'s operation object is put in the selected state are different.

17. The medium according to claim 16, wherein the program further has said computer execute a process of having the display unit change a color of the device'"'"'s operation object when the device'"'"'s operation object is selected.

18. The medium according to claim 16, wherein the program further has said computer execute a process of canceling the selected state according to a predetermined condition.
