Abstract

There is provided an information processing apparatus including an extraction section which extracts a first touch region and a second touch region, each satisfying a predetermined region extraction condition, from a plurality of touch positions detected by a touch panel, and a recognition section which recognizes an input event, based on a change in a distance between the first touch region and the second touch region.

Claims

1. An information processing apparatus, comprising:

an extraction section which extracts a first touch region and a second touch region, each satisfying a predetermined region extraction condition, from a plurality of touch positions detected by a touch panel; and

a recognition section which recognizes an input event, based on a change in a distance between the first touch region and the second touch region.

2. The information processing apparatus according to claim 1,

wherein in a case where the distance between the first touch region and the second touch region becomes smaller, the recognition section recognizes a first input event.

3. The information processing apparatus according to claim 1,

wherein in a case where the distance between the first touch region and the second touch region becomes larger, the recognition section recognizes a second input event.

4. The information processing apparatus according to claim 1,

wherein the recognition section recognizes the input event, based on an amount of change in the distance between the first touch region and the second touch region.

5. The information processing apparatus according to claim 1,

wherein the recognition section recognizes the input event, based on a relative moving direction between the first touch region and the second touch region.

6. The information processing apparatus according to claim 1,

wherein the recognition section recognizes the input event, based on a moving direction of the first touch region and a moving direction of the second touch region.

7. The information processing apparatus according to claim 1, further comprising:

a control section which changes a display of an object to be operated, which is displayed between the first touch region and the second touch region, according to the recognized input event.

8. The information processing apparatus according to claim 7,

wherein in a case where the distance between the first touch region and the second touch region becomes smaller, the recognition section recognizes a first input event, and

wherein in a case where the first input event is recognized, the control section repositions an object to be operated in a narrower range.

9. The information processing apparatus according to claim 7,

wherein in a case where the distance between the first touch region and the second touch region becomes smaller, the recognition section recognizes a first input event, and

wherein in a case where the first input event is recognized, the control section unites data corresponding to a plurality of objects to be operated displayed before the recognition of the first input event.

10. The information processing apparatus according to claim 9,

wherein the data is a moving image.

11. The information processing apparatus according to claim 7,

wherein in a case where the distance between the first touch region and the second touch region becomes larger, the recognition section recognizes a second input event, and

wherein in a case where the second input event is recognized, the control section repositions a plurality of objects to be operated in a wider range.

12. The information processing apparatus according to claim 7,

wherein in a case where the distance between the first touch region and the second touch region becomes larger, the recognition section recognizes a second input event, and

wherein in a case where the second input event is recognized, the control section aligns a plurality of objects to be operated displayed before the recognition of the second input event.

13. The information processing apparatus according to claim 7,

wherein in a case where the distance between the first touch region and the second touch region becomes larger, the recognition section recognizes a second input event, and

wherein in a case where the second input event is recognized, the control section divides data corresponding to one object to be operated displayed before the recognition of the second input event.

14. The information processing apparatus according to claim 13,

wherein the data is a moving image.

15. The information processing apparatus according to claim 1,

wherein the region extraction condition includes a condition for a size of a touch region to be extracted.

16. The information processing apparatus according to claim 1,

wherein the region extraction condition includes a condition for a shape of a touch region to be extracted.

17. The information processing apparatus according to claim 1,

wherein the region extraction condition includes a condition for a density of a touch position included in a touch region to be extracted.

18. An information processing method, comprising:

extracting a first touch region and a second touch region, each satisfying a predetermined region extraction condition, from a plurality of touch positions detected by a touch panel; and

recognizing an input event, based on a change in a distance between the first touch region and the second touch region.
