Abstract

A detected information correction apparatus configured to correct detected information, includes: a usage status detecting configured to detect status information on the basis of detected information detected by one or more sensors, the status information indicating how a portable apparatus is being used; a correction data acquiring configured to acquire correction data at specific timing intervals, the correction data being used to correct the detected information; and a detected information correcting configured to correct the detected information with the correction data.

Claims

1. A detected information correction apparatus comprising:

a memory which stores instructions; and

a computer processor coupled to the memory and executes the stored instructions which cause the computer processor to execute;

acquire gesture status information of a portable apparatus based on an output from a first sensor which is installed in the portable apparatus, the gesture status information indicating an orientation of the portable apparatus,

acquire grip position information from a second sensor which is installed in the portable apparatus, the grip position indicating a position of the portable apparatus where one or more hands grip,

acquire correction data according to the orientation and the grip position, and

correct the gesture status information with the correction data.

2. The detected information correction apparatus according to claim 1, wherein the detected gesture status information includes a first, a second, and a third angle, each being an angle between a surface and a first axis in a width direction of the portable apparatus, a second axis in a height direction of the portable apparatus, and a third axis in a depth direction of the portable apparatus, respectively,

the detected gesture status information further includes a first, a second, and a third acceleration, each being an acceleration along the first axis, the second axis, and the third axis, respectively, and

the acquired correction data includes a first, a second, and a third coefficient for multiplication with the first, second, and third acceleration, respectively, wherein each coefficient is a respective cosine of the detected first, second, and third angles.

3. The detected information correction apparatus according to claim 1, wherein

the detected gesture status information indicates whether shake is being produced in the portable apparatus,

the acquired correction data includes correction data for the shake, and

the computer processor executes to remove components of the shake expressed by the correction data for the shake from a wave that represents a variation in the detected gesture status information.

4. The detected information correction apparatus according to claim 1, wherein

the detected gesture status information additionally indicates whether shake is being produced in the portable apparatus, and

the computer processor executes to acquire correction data at timing intervals when the shake is detected.

8. The apparatus according to claim 1, wherein the detected gesture status information includes variation data of orientations of the portable apparatus and the correction data corrects the variation data to emphasize a movement along a certain axis from among direction axes set for the portable apparatus.

9. The apparatus according to claim 8, wherein the certain axis is determined according to one or more factors of misrecognition, recognition, user profile, portable apparatus location, or shake of the portable apparatus.

5. A portable apparatus, comprising:

a sensor;

a memory which stores instructions; and

a computer processor coupled to the memory and executes the stored instructions which cause the computer processor to execute;

acquire gesture status information of the portable apparatus based on an output from the sensor;

acquire correction data based on the gesture status information;

correct the gesture status information with the correction data; and

determine commands issued to the portable apparatus based upon the gesture status information which is corrected, and

wherein the gesture status information includes a first, a second, and a third angle, each being an angle between a surface and a first axis in a width direction of the portable apparatus, a second axis in a height direction of the portable apparatus, and a third axis in a depth direction of the portable apparatus, respectively,

the gesture status information further includes a first, a second, and a third acceleration, each being an acceleration along the first axis, the second axis, and the third axis, respectively, and

the correction data includes a first, a second, and a third coefficient for multiplication with the first, second, and third acceleration, respectively, wherein each coefficient is a respective cosine of the first, second, and third angles.

6. The portable apparatus according to claim 5, wherein

when a command differs from an intended command, the correction data acquirer acquires new correction data.

7. A detected information correction method for execution by a computer processor for a portable apparatus, the method comprising:

executing by the computer processor;

acquiring gesture status information of the portable apparatus based on an output from a first sensor which is installed in the portable apparatus, the gesture status information indicating an orientation of the portable apparatus;

acquiring grip position information from a second sensor which is installed in the portable apparatus, the grip position indicating a position of the portable apparatus where one or more hands grip; and

correcting the gesture status information according to correction data acquired based on the orientation and the grip position.
