Abstract

An information processing apparatus includes: a processor configured to acquire position information of a communication device; and a storage configured to store first map information and second map information. The processor is further configured to, in a case in which the processor acquires position information a predetermined number of times of at least two or more, in a first partial area of plurality of first partial areas, determine that the communication device exists in the first partial area. The processor is further configured to, in a case in which the processor acquires position information a predetermined number of times of at least two or more, in a second partial area of plurality of second partial areas, determine that the communication device exists in the second partial area.

First claim

The invention claimed is:

1. An information processing apparatus comprising:
a processor configured to acquire position information of a communication device; and
a storage configured to store first map information and second map information, the first map information indicating a plurality of first partial areas that divide an area in which the communication device is movable, the second map information indicating a plurality of second partial areas that divide the area, each of the plurality of second partial areas being smaller than each of the plurality of first partial areas; wherein:
the processor is further configured to:
in a case in which the processor acquires position information a predetermined number of times of at least two or more, in a first partial area of the plurality of first partial areas, based on the first map information, determine that the communication device exists in the first partial area, and
in a case in which the processor acquires position information a predetermined number of times of at least two or more, in a second partial area of the plurality of second partial areas, based on the second map information, determine that the communication device exists in the second partial area.

2. The information processing apparatus according to claim 1 , wherein the predetermined number of times is a detection set value that is variable.

3. The information processing apparatus according to claim 2 , wherein the detection set value can be set with respect to each first partial area of the plurality of first partial areas or each second partial area of the plurality of second partial areas.

4. The information processing apparatus according to claim 2 , wherein:
the processor is configured to:
in a case in which position information is continuously acquired at least a number of times equal to the detection set value, in a first partial area of the plurality of first partial areas, determine that the communication device exists in the first partial area, and
in a case in which position information is continuously acquired at least a number of times equal to the detection set value, in a second partial area of the plurality of second partial areas, determine that the communication device exists in the second partial area.

5. The information processing apparatus according to claim 1 , wherein:
the processor is configured to, when the communication device moves from a subject first partial area to another first partial area in the plurality of first partial areas:
upon determining that the communication device exists in the subject first partial area, determine that an entering event occurs, the entering event indicating that the communication device has entered the subject first partial area; and
upon determining that the communication device exists in another first partial area other than the subject first partial area after the entering event occurs, determine that a leaving event occurs, the leaving event indicating that the communication device has left the subject first partial area.

6. The information processing apparatus according to claim 1 , wherein:
the processor is configured to, when the communication device moves from a subject second partial area to another second partial area in the plurality of second partial areas:
upon determining that the communication device exists in the subject second partial area, determine that an entering event occurs, the entering event indicating that the communication device has entered the subject second partial area, and
upon determining that the communication device exists in another second partial area other than the subject second partial area after the entering event occurs, determine that a leaving event occurs, the leaving event indicating that the communication device has left the subject second partial area.

7. The information processing apparatus according to claim 5 , wherein the processor is further configured to output event type information of at least one of the entering event and the leaving event that has been determined.

8. The information processing apparatus according to claim 7 , wherein the processor is further configured to count time, and to output time and the event type information in an associated manner.

9. The information processing apparatus according to claim 8 , wherein time that is associated with the event type information is a time when the communication device is determined as existing in the first partial area or the second partial area.

10. The information processing apparatus according to claim 5 , wherein the processor is configured to, in response to occurrence of the entering event at the another first partial area before the leaving event at the subject first partial area occurs, forcibly generate the leaving event at the subject first partial area.

11. The information processing apparatus according to claim 1 , wherein:
the processor is further configured to:
count a number of times that the position information acquired by the processor indicates that the communication device exists in the first partial area or the second partial area and

reset the number of times that has been counted with respect to the first partial area or the second partial area, in a case in which the number of times does not reach the predetermined number of times within a predetermined time.

12. The information processing apparatus according to claim 11 , wherein the processor is configured to restart counting a number of times that the communication device exists in the first partial area or the second partial area, after resetting the counted number of times.

13. An information processing system comprising:
the information processing apparatus according to claim 1 ; and
a communication terminal configured to communicate with the information processing apparatus;
wherein the communication terminal is configured to display a first partial area or a second partial area in which the communication device is determined as existing, the predetermined number of times, so that the first partial area or the second partial area is visually distinguished from other first partial areas or other second partial areas.

14. The information processing system according to claim 13 , wherein, when the communication terminal requests position information of the communication device to an information processing terminal, the information processing apparatus causes the communication terminal to display position information of the communication device in the second map information, in a condition in which the communication device is determined as existing in both of the first partial area and the second partial area.

15. The information processing system according to claim 13 , wherein, when the communication terminal requests position information of the communication device to the information processing terminal, the information processing apparatus causes the communication terminal to display position information of the communication device in the first map information and in the second map information, in a condition in which the communication device is determined as existing in both of the first partial area and the second partial area.

16. The information processing system according to claim 13 , further comprising:
a locator configured to receive a radio wave that is emitted from the communication device; and
a position identification device configured to measure a position of the communication device based on an angle of arrival of the radio wave that is received by the locator;
wherein the information pr
