Abstract

Provided is an information processing apparatus including a course setting unit that sets a course containing at least one place associated with positional information, a course information generation unit that generates first course information regarding the course on the basis of first user behavior information generated from a behavior of a first user having visited the course, and a course information provision unit that provides the first course information to a second user different from the first user.

Claims

1. An information processing apparatus comprising:

circuitry configured to

set a course containing at least one place associated with positional information,

generate first course information regarding the course on the basis of first user behavior information generated from a behavior of a first user having visited the course,

calculate a moving speed of the first user on the basis of a history of positional information of the first user,

distinguish between a staying period and a moving period of the first user on the basis of the moving speed,

identify a location of the first user in the staving period as a place the first user has visited, and

provide the first course information to a second user different from the first user.

2. The information processing apparatus according to claim 1, wherein the circuitry is configured to

generate the first course information which displays, in association with the place, the first user behavior information generated at the place when the place the first user has visited is contained in the course.

3. The information processing apparatus according to claim 2, wherein the circuitry is configured to

further identify a place the second user has visited, and

update the first course information by additionally associating, with the place, second user behavior information generated from a behavior of the second user at the place when the place the second user has visited is contained in the course.

4. The information processing apparatus according to claim 3, wherein

the circuitry is configured to update the first course information by adding a new place to the first course information and associating the second user behavior information with the place when the place the second user has visited is not contained in the course.

5. The information processing apparatus according to claim 4, wherein

the circuitry is configured to add a new place to the first course information and also add the place to the course.

6. The information processing apparatus according to claim 2, wherein

the circuitry is configured to set the course containing the place the first user has visited.

7. The information processing apparatus according to claim 2, wherein the circuitry is configured to

further identify a place the second user has visited, and

when the place the second user has visited is contained in the course, generate second course information regarding the course, the second course information displaying, in association with the place, second user behavior information generated from a behavior of the second user at the place.

8. The information processing apparatus according to claim 2, wherein the circuitry is configured to

identify a moving route of the first user, and

generate the first course information which displays, on the moving route, the place the first user has visited.

9. The information processing apparatus according to claim 8, wherein

the circuitry is configured to calculate a moving acceleration of the first user on the basis of a history of the positional information, remove noise data from the history of the positional information on the basis of the moving acceleration, and then, trace the history of the positional information to identify the moving route.

10. The information processing apparatus according to claim 9, wherein

when the moving acceleration when the first user moves from a first point to a second point is larger than a positive threshold, the circuitry is configured to remove data corresponding to the second point as the noise data.

11. The information processing apparatus according to claim 9, wherein

when the moving acceleration when the first user moves from a first point to a second point is smaller than a negative threshold, the circuitry is configured to refer to a history of a moving distance of the last three sections having, as a latest section, a section from the first point to the second point, and remove, as the noise data, data corresponding to a point sandwiched by sections of the last three sections the moving distance of which is not smallest.

12. The information processing apparatus according to claim 1, wherein

the circuitry is configured to distinguish a period in which the moving speed is smaller than a first threshold as the staying period and distinguish a period in which the moving speed is larger than the first threshold as the moving period.

13. The information processing apparatus according to claim 12, wherein

when a difference between the first threshold and a local maximum value or a local minimum value of the moving speed in a first staying period or a first moving period is smaller than or equal to a predetermined value, the circuitry is configured to combine the first staying period or the first moving period with a second staying period or a second moving period before or after the first staying period or the first moving period.

14. The information processing apparatus according to claim 13, wherein

the circuitry is configured to combine the first staying period or the first moving period with one of the second staying period and the second moving period which has a larger difference between the first threshold and the local maximum value or the local minimum value of the moving speed in the period than the other has.

15. The information processing apparatus according to claim 14, wherein

the first threshold is set on the basis of a frequency of staying and a frequency of moving for each moving speed in a behavior recognition result for the first user or a behavior recognition result for an average user.

16. The information processing apparatus according to claim 1, wherein

the circuitry is configured to calculate a moving acceleration of the first user on the basis of the history of the positional information, remove noise data from the history of the positional information on the basis of the moving acceleration, and then, calculate the moving speed of the first user on the basis of the history of the positional information.

17. An information processing method comprising:

setting a course containing at least one place associated with positional information;

generating first course information regarding the course on the basis of first user behavior information generated from a behavior of a first user having visited the course;

calculating a moving speed of the first user on the basis of a history of positional information of the first user;

distinguishing between a staying period and a moving period of the first user on the basis of the moving speed;

identifying a location of the first user in the staying period as a place the first user has visited; and

providing the first course information to a second user different from the first user.

18. A non-transitory computer-readable storage medium including computer executable instructions, wherein the instructions, when executed by a computer, cause the computer to perform a method, the method comprising:

setting a course containing at least one place associated with positional information;

generating first course information regarding the course on the basis of first user behavior information generated from a behavior of a first user having visited the course;

calculating a moving speed of the first user on the basis of a history of positional information of the first user;
