Abstract

In one embodiment, the information processing apparatus includes an acceleration sensor configured to detect acceleration of the information processing apparatus, and a display part configured to include a screen for displaying an image. The apparatus further includes a determination part configured to determine whether a displayed position of the image is to be corrected, based on duration of a state in which the acceleration occurs in a predetermined direction. The apparatus further includes a correction part configured to correct the displayed position of the image according to the determination made by the determination part.

Claims

1. An information processing apparatus comprising:

an acceleration sensor configured to detect acceleration of the information processing apparatus;

a display module configured to include a screen for displaying an image;

a determination module configured to determine to correct a displayed position of the image when duration of a state in which the acceleration occurs in a predetermined direction is longer than a threshold; and

a correction module configured to correct the displayed position of the image according to the determination made by the determination module,

wherein

the predetermined direction is opposite to a direction in which gravity acts, and

the correction module is configured to determine a correction amount of the displayed position, based on a value of the acceleration in the predetermined direction, and configured to vary the correction amount, based on an inclination of the information processing apparatus.

3. The apparatus of claim 1, wherein

determination module is configured to determine not to correct the displayed position when the duration is shorter than the threshold.

5. The apparatus of claim 1, wherein

the correction module is configured to determine the correction amount, based on an increment of the acceleration during a fixed period.

6. The apparatus of claim 1, wherein

the correction module is configured to determine the correction amount, based on a value obtained by integrating the acceleration twice with respect to time.

8. The apparatus of claim 1, wherein

the correction module is configured to determine the correction amount, based on the duration.

9. The apparatus of claim 1, wherein the correction module comprises:

a position change calculating module configured to calculate a change in position of the information processing apparatus, based on a value of the acceleration in the predetermined direction;

a reaching point estimating module configured to estimate a maximum reaching point and a minimum reaching point of a change in position of a user of the information processing apparatus, based on a result of the calculation of the change in position of the information processing apparatus;

a position change estimating module configured to estimate the change in position of the user, based on the maximum reaching point and the minimum reaching point; and

a correction amount determining module configured to determine the correction amount of the displayed position, based on the result of the calculation of the change in position of the information processing apparatus and a result of the estimation of the change in position of the user.

10. The apparatus of claim 9, wherein

the position change estimating module is configured to estimate the change in position of the user by interpolation with the maximum reaching point and the minimum reaching point.
