Abstract

The operating state of a computer is switched only when moving of the computer is detected. An information processing device has a detection unit, which detects, as a lifting action, a fact that an accelerated velocity has been kept applied in one direction for a given period of time, and a control unit, which executes a predetermined control operation that is associated with the lifting action detected by the detection unit. A lifting action detecting method has a detection step of detecting, as a lifting action, the fact that an accelerated velocity has been kept applied in one direction for a given period of time, and a control step of executing a predetermined control operation that is associated with the lifting action detected in the detection step.

a control unit which executes a predetermined control operation that is associated with the lifting action detected by the detection unit.

2. An information processing device according to claim 1, wherein the control operation is for putting at least some of components of the information processing device out of operation.

3. An information processing device according to claim 1, wherein the detection unit detects the lifting action when the accelerated velocity is within a given range.

4. A lifting action detecting method, comprising:

a detection step of detecting, as a lifting action, a fact that an accelerated velocity has been kept applied in one direction for a given period of time; and

7. A readable-by-computer medium recorded with a program for causing a computer to execute:

a detection step of detecting, as a lifting action, a fact that an accelerated velocity in one direction has lasted a given period of time; and

a notification step of notifying an application program of the lifting action detected in the detection step.

8. A readable-by-computer medium recorded with a program according to claim 7, wherein the application program is for putting at least some of components of an information processing device out of operation.

9. A readable-by-computer medium recorded with a program according to claim 7, wherein the detection step is a step of detecting the lifting action only when the accelerated velocity is within a given range.

10. An information processing device, which is connected to an acceleration sensor capable of detecting at least an accelerated velocity along one axis, comprising:
