Abstract

An information processing device is disclosed. The information processing device includes an inclination detection unit configured to generate a first signal regarding inclination of the device. The information processing device also includes a display processing unit configured to, based on the first signal, generate a second signal to initiate a change in orientation of a display of content, and generate a third signal to cancel the change in orientation in response to receipt of a CANCEL command after initiation of the change.

Claims

1. An information processing device comprising:

an inclination detection unit configured to detect inclination of the device; and

a display processing unit configured to;

initiate, when the detected inclination of the device is at least at or over a threshold angle, a change in orientation of a display of content; and

cancel the change in orientation in response to receipt of a CANCEL command received during a period of time after initiation of the change,

wherein the period of time is a predetermined period of time for the change in orientation of the display of the content to be completed, and

wherein the inclination detection unit and the display processing unit are each implemented via at least one processor.

2. The information processing device according to claim 1, further comprising:

a rotation detection unit configured to detect an angular velocity of the device, and communicate with the display processing unit,

wherein the rotation detection unit is implemented via at least one processor.

3. The information processing device according to claim 2, wherein the period of time is determined in accordance with a result of detecting the angular velocity by the rotation detection unit.

4. The information processing device according to claim 2, wherein the display processing unit determines whether the device is rotated intentionally or not in accordance with the angular velocity detected by the rotation detection unit.

5. The information processing device according to claim 1, wherein the threshold angle is 90 degrees.

6. The information processing device according to claim 1, wherein the display processing unit is further configured to display an animation during the period of time after initiation of the change.

7. An information processing method comprising:

detecting an inclination of a device;

initiating, when the detected inclination of the device is at least at or over a threshold angle, a change in orientation of a display of content; and

canceling the change in orientation in response to receipt of a CANCEL command received during a period of time after initiation of the change,

wherein the period of time is a predetermined period of time for the change in orientation of the display of the content to be completed.

8. The information processing method according to claim 7, further comprising:

detecting an angular velocity of the device.

9. The information processing method according to claim 8, wherein the period of time is determined in accordance with a result of detecting the angular velocity.

10. The information processing method according to claim 8, further comprising:

determining whether the device is rotated intentionally or not in accordance with the detected angular velocity.

11. A non-transitory computer-readable medium having embodied thereon a program, which when executed by a computer causes the computer to execute an information processing method, the method comprising:

detecting an inclination of a device;

initiating, when the detected inclination of the device is at least at or over a threshold angle, a change in orientation of a display of content; and

canceling the change in orientation in response to receipt of a CANCEL command received during a period of time after initiation of the change,

wherein the period of time is a predetermined period of time for the change in orientation of the display of the content to be completed.
