Abstract

The information processing apparatus according to the present invention includes an input position detecting unit that detects a position of an operator positioned on an operation input unit; a direction detecting unit that detects a moving direction of the operator based on a time variation of the detected position of the operator; a reproduction speed changing unit that changes a reproduction speed of the contents that vary with elapse of time displayed in a screen according to the number of operators detected by the input position detecting unit, and a reproducing direction changing unit that changes a reproducing direction of the contents displayed in the screen according to the moving direction of the of the operator detected by the direction detecting unit.

Claims

1. An information processing apparatus, comprising:

an input position detecting unit that detects a position of an operator positioned on an operation input unit;

a direction detecting unit that detects a moving direction of the operator based on a time variation of the detected position of the operator;

a reproduction speed changing unit that changes a reproduction speed of contents varying with elapse of time displayed in a screen according to the number of operators detected by the input position detecting unit; and

a reproducing direction changing unit that changes a reproducing direction of the contents displayed in the screen according to the moving direction of the operator detected by the direction detecting unit.

2. The information processing apparatus according to claim 1, wherein the input position detecting unit outputs coordinates of the operator positioned on the operation input unit, and

the reproduction speed changing unit changes the reproduction speed according to the number of coordinates of the operators simultaneously transmitted from the input position detecting unit.

3. The information processing apparatus according to claim 2, wherein the reproduction speed changing unit increases the reproduction speed as the number of the operators is increased, and decreases the reproduction speed as the number of the operators is decreased.

4. The information processing apparatus according to claim 3, wherein the reproducing direction changing unit changes the reproducing direction to a direction of forwarding a reproduction elapse time of the contents when the moving direction is approximately the same as a direction of elapse time in the contents, and the reproducing direction is changed to a direction of rewinding the reproduction elapse time of the contents when the moving direction is opposite to the direction of elapse time in the contents.

5. The information processing apparatus according to claim 4, wherein the direction detecting unit selects a direction corresponding to a sum of vectors formed by a locus drawn by each of the operators as the moving direction, when the number of the operators is plural number.

6. The information processing apparatus according to claim 2, wherein the direction detecting unit determines a movement of the operators when the coordinates of the operators transmitted from the input position detecting unit change to a predetermined threshold value or more.

7. An information processing method, comprising the steps of:

detecting a position of an operator positioned on an operation input unit;

detecting a moving direction of the operator based on a time variation of the detected position of the operator;

changing a reproduction speed of contents varying with elapse of time displayed in a screen according to the number of detected operators; and

changing a reproducing direction of the contents displayed in the screen according to the moving direction of the operator detected by the direction detecting unit.

8. A program for causing a computer having an operation input unit to realize:

an input position detecting function of detecting a position of an operator positioned on the operation input unit;

a direction detecting function of detecting a moving direction of the operator based on a time variation of the detected position of the operator;

a reproduction speed changing function of changing a reproduction speed of contents varying with elapse of time displayed in a screen according to the number of operators detected by the input position detecting function; and

a reproducing direction changing function of changing a reproducing direction of the contents displayed in the screen according to a moving direction of the operator detected by the direction detecting function.
