Abstract

A playback apparatus is provided that includes an operation plane, a detection unit to detect which of contact relationship including first contact relationship, second contact relationship with a higher degree of contact than the first contact relationship and third contact relationship with a higher degree of contact than the second contact relationship the operation plane and an operation object have, a creation unit to create a list screen of content data for selecting content data based on movement of the operation object with respect to the operation plane in the first contact relationship, a playback unit to play back content data, and a playback control unit to cause the playback unit to play back content data selected on the list screen when becoming the second contact relationship from the first contact relationship if contact relationship becomes the third contact relationship from the second contact relationship.

Claims

1. A playback apparatus comprising:

an operation plane;

a detection unit to detect a first contact relationship, a second contact relationship, and a third contact relationship between the operation plane and an operation object, the second contact relationship including a higher degree of contact than the first contact relationship, and the third contact relationship having a higher degree of contact than the second contact relationship;

a creation unit to create a list screen of content data allowing selection of content data based on movement of the operation object with respect to the operation plane while in the first contact relationship, the content data selected being in close proximity to a position on the list screen specified by movement of the operation object;

a playback unit configured to play back the content data; and

a playback control unit configured to control the playback unit to play back the content data, which is selected on the list screen when the contact relationship moves from the first contact relationship to the second contact relationship, when the contact relationship moves from the second contact relationship to the third contact relationship.

2. The playback apparatus according to claim 1, wherein

the playback control unit causes the playback unit to play back the content data selected while the operation plane and the operation object are in the first contact relationship from a particular part of the content data.

3. The playback apparatus according to claim 1, wherein

a shift amount of the position on the list screen specified by movement of the operation object with respect to the operation plane becomes smaller in relation to the same movement of the operation object as a degree of contact between the operation plane and the operation object increases.

4. The playback apparatus according to claim 1, wherein

a moving speed of the position on the list screen specified by movement of the operation object with respect to the operation plane becomes lower in relation to the same movement of the operation object as a degree of contact between the operation plane and the operation object increases.

5. The playback apparatus according to claim 1, wherein

the creation unit creates an image display screen containing images respectively indicating selected content data and the content data associated with a peripheral position of the content data, in addition to the list screen.

6. The playback apparatus according to claim 5, wherein

the creation unit enlarges the images contained in the image display screen as a degree of contact between the operation plane and the operation object increases.

7. The playback apparatus according to claim 6, wherein

the creation unit creates a playback screen of the content data to be played back when contact relationship between the operation plane and the operation object becomes the third contact relationship.

8. The playback apparatus according to claim 1, wherein

the creation unit enlarges a peripheral part of selected content data on the list screen and displays an image indicating the content data associated with the peripheral part in a corresponding position when contact relationship between the operation plane and the operation object becomes the second contact relationship.

9. The playback apparatus according to claim 1, wherein

the detection unit detects contact relationship between the operation plane and the operation object based on at least one of pressure on the operation plane and a contact area of the operation object with the operation plane.

10. The playback apparatus according to claim 1, wherein

the first contact relationship is relationship where the operation plane and the operation object are separated.

11. The playback apparatus according to claim 1, further comprising:

a vibration control unit to vibrate a vibrator according to beat of content data being played back by the playback unit.

12. A playback method comprising the steps of:

detecting a first contact relationship, a second contact relationship, and a third contact relationship between an operation plane and an operation object, the second contact relationship including a higher degree of contact than the first contact relationship, and the third contact relationship having a higher degree of contact than the second contact relationship;

creating a list screen of content data allowing selection of content data based on movement of the operation object with respect to the operation plane when the operation plane and the operation object have the first contact relationship, the content data selected being in close proximity to a position on the list screen specified by movement of the operation object; and

playing back content data, selected on the list screen when the contact relationship moves from the first contact relationship to the second contact relationship, when the contact relationship moves from the second contact relationship to the third contact relationship.

13. A program for causing a computer to function as a playback apparatus comprising:

an operation plane;

a detection unit to detect a first contact relationship, a second contact relationship, and a third contact relationship between the operation plane and an operation object, the second contact relationship including a higher degree of contact than the first contact relationship, and the third contact relationship having a higher degree of contact than the second contact relationship;

a creation unit to create a list screen of content data allowing selection of content data based on movement of the operation object with respect to the operation plane while in the first contact relationship, the content data selected being in close proximity to a position on the list screen specified by movement of the operation object;

a playback unit configured to play back the content data; and

a playback control unit configured to control the playback unit to play back the content data, which is selected on the list screen when the contact relationship moves from the first contact relationship to the second contact relationship, when the contact relationship moves from the second contact relationship to the third contact relationship.
