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.

Claims

1. An information processing device, which is connected to an acceleration sensor to detect an accelerated velocity along at least one axis, comprising:

a correction instruction input unit in which a correction instruction from a user is entered;

an acceleration measuring unit which uses the acceleration sensor in response to the correction instruction to obtain, more than once, a measurement value about an accelerated velocity that is applied to the information processing device along at least one axis;

a measurement value judging unit which judges whether the measurement values about the accelerated velocity obtained through measurement by the acceleration measuring unit are within a specific range;

a correction value creating unit which, when the measurement values about the accelerated velocity are judged to be within the specific range by the measurement value judging unit, creates a correction value for the acceleration sensor based on the measurement values about the accelerated velocity; and

a correcting unit which corrects the measurement values about the accelerated velocity with the correction value.

2. The information processing device according to claim 1, further comprising a maximum value judging unit which judges whether or not the measurement values are equal to or smaller than a first value.

3. The information processing device according to claim 1, further comprising a minimum value judging unit which judges whether or not the measurement values are equal to or larger than a second value.

4. An information processing device according to claim 1, further comprising a self-diagnostic driver which applies a voltage to a connection line that connects the acceleration sensor and the information processing device.

5. A correction method of correcting an information processing device, which is connected to an acceleration sensor to detect an accelerated velocity along at least one axis, comprising:

accepting a correction instruction from a user;

using the acceleration sensor in accordance with the correction instruction to obtain, more than once, a measurement value about an accelerated velocity that is applied to the information processing device along at least one axis;

judging whether the measurement values are within a specific range;

creating, when the measurement values about the accelerated velocity are judged to be within the specific range, a correction value for the acceleration sensor based on the measurement values about the accelerated velocity; and

correcting the measurement values about the accelerated velocity with the correction value.

6. The correction method according to claim 5, further comprising judging whether or not the measurement values are equal to or smaller than a first value.

7. The correction method according to claim 5, further comprising judging whether or not the measurement values are equal to or larger than a second value.

8. The correction method according to claim 5, further comprising making a self-diagnosis with a use of a self-diagnostic driver which applies a voltage to a connection line that connects the acceleration sensor and the information processing device.

9. A readable-by-computer medium recorded with a correction program for causing a computer, which is connected to an acceleration sensor to detect an accelerated velocity along at least one axis, to execute:

accepting a correction instruction from a user;

using the acceleration sensor in accordance with the correction instruction to obtain, more than once, a measurement value about an accelerated velocity that is applied to the information processing device along at least one axis;

judging whether the measurement values are within a specific range;

creating, when the measurement values about the accelerated velocity are judged to be within the specific range, a correction value for the acceleration sensor based on the measurement values about the accelerated velocity; and

correcting the measurement values about the accelerated velocity with the correction value.

10. The readable-by-computer medium recorded with a correction program according to claim 9, further comprising judging whether or not the measurement values are equal to or smaller than a first value.

11. The readable-by-computer medium recorded with a correction program according to claim 9, further comprising judging whether or not the measurement values are equal to or larger than a second value.

12. The readable-by-computer medium recorded with a correction program according to claim 9, further comprising making a self-diagnosis with the use of a self-diagnostic driver which applies a voltage to a connection line that connects the acceleration sensor and the information processing device.
