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 an operation object;

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

a control unit that performs a first operation assessment for detecting whether or not an outer peripheral distance of a first area formed by connecting adjacent push-down points among a plurality of push-down points detected by said tactile contact detection unit decreases over time to a predetermined value or less, and that performs a second operation assessment for detecting whether or not an outer peripheral distance of a second area formed by connecting adjacent push-down points among a plurality of push-down points detected by said tactile contact detection unit increases over time to a predetermined value or more, wherein

said control unit puts said operation object in a selected state when there is an overlapping part between said operation object and said first area after said first operation assessment, and performs a first operation corresponding to a place where said second operation assessment has been performed on said operation object.

2. The information processing device according to claim 1, wherein said control unit performs said second operation assessment when said tactile contact detection unit detects the same number of push-down points as that of the push-down points forming said first area in said second operation assessment.

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

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

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

6. The information processing device according to claim 1, wherein said first operation moves said operation object to the place where said second operation assessment has been performed.

7. 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.

8. The information processing device according to claim 1, wherein said control unit performs a predetermined second operation when there is no overlapping part between said operation object and said first area after said first operation assessment, and performs a third operation corresponding to said second operation when said second operation assessment is performed.

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

a display unit that displays an operation object; and

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

performing a first operation assessment that detects whether or not an outer peripheral distance of a first area formed by connecting adjacent push-down points among a plurality of push-down points detected by said tactile contact detection unit decreases over time to a predetermined value or less;

selecting said operation object when there is an overlapping part between said operation object and said first area;

performing a second operation assessment that detects whether or not an outer peripheral distance of a second area formed by connecting adjacent push-down points among a plurality of push-down points detected by said tactile contact detection unit increases over time to a predetermined value or more; and

performing a first operation corresponding to a place where said second operation assessment has been performed on said operation object.

11. The control method for an information processing device according to claim 9, wherein the second operation assessment is performed when the tactile contact detection unit detects the same number of push-down points as that of the push-down points forming the first area.

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

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

14. The control method for an information processing device according to claim 9, wherein a plurality of the operation objects overlapping the first area are selected in the selecting the operation objects.

15. The control method for an information processing device according to claim 9, wherein the first operation moves the operation object to the place where the second operation assessment has been performed.

16. 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 operation object is selected.

17. The control method for an information processing device according to claim 9, further including performing a predetermined second operation when there is no overlapping part between the operation object and the first area, and performing a third operation corresponding to the second operation when the second operation assessment is performed.

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

a display unit that displays an operation object; and

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

a first operation assessment process of detecting whether or not an outer peripheral distance of a first area formed by connecting adjacent push-down points among a plurality of push-down points detected by said tactile contact detection unit decreases over time to a predetermined value or less;

a process of selecting said operation object when there is an overlapping part between said operation object and said first area;

a second operation assessment process of detecting whether or not an outer peripheral distance of a second area formed by connecting adjacent push-down points among a plurality of push-down points detected by said tactile contact detection unit increases over time to a predetermined value or more; and

a process of performing a first operation corresponding to a place where said second operation assessment process has been performed on said operation object.

18. The medium according to claim 10, wherein the second operation assessment process is executed when the tactile contact detection unit detects the same number of push-down points as that of the push-down points forming the first area.

19. The medium according to claim 10, the program executing a process of having the display unit change the color of the operation object when the operation object is selected.

20. The medium according to claim 10, the program executing a process of canceling the selected state according to a predetermined condition.
