Information processing apparatus, information processing method, and recording medium
An information processing apparatus, method, and recording medium which acquire movement trace information and automatically determine a division point for dividing the movement trace information based on an analysis result of the movement trace information. Optionally a movement trace track is generated from the movement trace. Various criteria used for how the division points are generated include using distance and time; altitudes; repeated track; mode of transportation; and lapse of data, for example.

a computer processing unit that automatically divides the movement trace information at a division point into a first movement trace segment and a second movement trace segment, wherein
the computer processing unit automatically determines the division point based on content data associated with the movement trace information, and
the computer processing unit adds a content data segment, for the content data, in between the first movement trace segment and the second movement trace segment, and the computer processing unit is configured to generate a movement trace track from the movement trace information; and an interface through which the computer processing unit outputs a display signal that causes a display device to display the movement trace track that includes the first movement trace segment, the second movement trace segment, a visual indication of the division point and the content data segment, wherein the movement trace track is represented by a bar having a length according to a movement time.
2. The apparatus of claim 1 , wherein
the computer processing unit automatically determines an additional division point based on position information of a stay part.
3. The apparatus of claim 2 , wherein
said stay part includes a plurality of stay positions within a predetermined geographic area over a predetermined time period.
4. The apparatus of claim 3 , wherein
one of the plurality of stay positions is set when position information of a movement trace track is continuously contained within the predetermined area for an hour or more.
5. The apparatus of claim 1 , wherein
the computer processing unit automatically determines an additional division point based on altitude information.
6. The apparatus of claim 5 , wherein
the altitude information includes time-series altitude changes of the movement trace information, and
the computer processing unit determines an additional division point at a peak altitude within a predetermined time period.
7. The apparatus of claim 6 , wherein
the computer processing unit does not set the additional division point at the peak altitude when inclination angle information is less than a predetermined threshold.
8. The apparatus of claim 1 , wherein
the computer processing unit automatically determines an additional division point based on detection of an orbiting movement in the movement trace information.
9. The apparatus of claim 1 , wherein
the computer processing unit automatically determines an additional division point based on a change in transportation mode.
10. The apparatus of claim 9 , wherein
the computer processing unit detects a change in speed of the movement trace information, and
determines that the transportation mode has changed when the change in speed is above a predetermined level.
11. The apparatus of claim 1 , wherein
the content data is associated in time with a position in the movement trace information.
12. The apparatus of claim 1 , wherein
the content data includes at least one of a photograph, a video recording, and an audio recording.
13. The apparatus of claim 1 , wherein
the computer processing unit automatically determines an additional division point based on a lapse of position data.
14. The apparatus of claim 1 , wherein
the computer processing unit automatically determines an additional division point based on at least one of time of day and day of week.
15. The apparatus of claim 1 , wherein
the computer processing unit automatically determines an additional division point based on predefined user settable track segments.
16. The apparatus of claim 1 , wherein
the first movement trace segment and the second movement trace segment are each a segment that does not include the content data.
17. The apparatus of claim 1 , wherein
the content data segment is a segment that does not include the movement trace information.
18. An information processing method comprising:
retrieving, from a non-transitory computer readable medium, movement trace information;
automatically dividing, with a computer processing unit, the movement trace information at a division point, based on content data associated with the movement trace information, into a first movement trace segment and a second movement trace segment; and
adding, with the computer processing unit, a content data segment, for the content data, in between the first movement trace segment and the second movement trace segment, generating, with the computer processing unit, a movement trace track from the movement trace information, displaying, on a display device, the movement trace track that includes the first movement trace segment, the second movement trace segment, a visual indication of the division point and the content data segment, wherein the movement trace track is represented by a bar having a length according to a movement time.
19. A non-transitory computer readable storage device having instructions that when executed by a computer processing unit performs an information processing method comprising:
retrieving, from the non-transitory computer readable medium, movement trace information;
automatically dividing, with the computer processing unit, the movement trace information into a first movement trace segment and a second movement trace segment at a division point based on content data associated with the movement trace information; and
adding, with the computer processing unit, a content data segment, for the content data, in between the first movement trace segment and the second movement trace segment, generating, with the computer processing unit, a movement trace track from the movement trace information, displaying, on a display device, the movement trace track that includes the first movement trace segment, the second movement trace segment, a visual indication of the division point and the content data segment, wherein the movement trace track is represented by a bar having a length according to a movement time.
20. The apparatus of claim 16 , wherein
the content data segment is a segment that does not include the movement trace information.
