FIG. 8 is a diagram showing a first example of the sensor log according to this embodiment.
The sensor log SL10 is an example of the above-mentioned second log. The sensor log SL10 is configured by accumulating detection information indicating the number of people detected by a sensor installed in the air conditioner AC. The sensor log SL10 is configured to include device identification information (device ID), detection time information, and detection information (detected number of people) for each detection.
In the example shown in the second row of FIG. 8, the device identification information is “B001” indicating the air conditioner AC, the detection time is 43 seconds on November 28, 2018, and the number of people detected is 1 person as the detection information. Indicates that.

As exemplified by the detection information, the detection information detected by the detection unit of the second device installed in a different space in the same space as the first device is detected by the user who can use the first device or It is used to determine the number of users. Therefore, the detection direction of the detection unit of the second device can be oriented to face the front surface of the first device in a normal use state. Assuming that the detection unit is installed in the television receiver TV (FIG. 1) as an example of the first device, there is a risk that the user in front of the television receiver TV may be shielded and other users may not be detected. is there. As in this example, by using the detection unit of the air conditioner AC as an example of the second device, it is possible to avoid the shielding by the user located in front of the first device, and thus it is possible to improve the detection accuracy of the user. Moreover, since the increase in the number of parts can be suppressed by utilizing the detection unit for exhibiting the function of the second device, it is possible to achieve an economical realization.

FIG. 9 is a diagram showing a second example of the sensor log according to this embodiment.
The sensor log SL12 is an example of the above-mentioned second log. The sensor log SL12 is configured by accumulating detection information indicating devices detected by the communication unit included in the air purifier AR.

In addition, each information terminal device 30 includes an oscillator that emits a sound wave in a predetermined frequency band (for example, an ultrasonic wave having a frequency higher than an audible band that can be heard by humans), and the air purifier AR detects an incoming sound wave. A sensor may be provided. The identification information of each information terminal device 30 may be conveyed by a sound wave. Sound waves coming from the outdoor information terminal device 30 are blocked by the wall of the room where the air purifier AR is installed. Therefore, the air purifier AR can find the information terminal device 30 in the same space based on the received signal by the sound wave received by the sensor.
In the example shown in the second row of FIG. 9, the device identification information is “C001” indicating the air purifier AR, the detection time is November 28, 2018, 43 seconds, and one device identification information “ S002” is included.

As exemplified by the detection information, the detection information indicating the device or the number of devices detected by the communication unit of the second device installed in the space common to the first device is the user who can use the first device. Alternatively, it is used to determine the number of users. Therefore, when each user carries a device that can communicate with the communication unit of the first device in the same space as the first device, the user who uses the first device can detect the device and use the first device. It can be determined as a detection. Since it is not necessary to provide the second device with a dedicated detection unit for detecting the user, economical realization can be achieved.

(Example of generating analysis result information)
Next, an example of generating analysis result information will be described. FIG. 10 is a diagram showing a first example of analysis result information according to the present embodiment.

The identification information “S001”, “S002”, “S003”, and “S004” is shown, and “4” is shown as the group attribute information. The service ID is information indicating individual broadcasting services, that is, individual broadcasting channels in all broadcasting areas. The “power OFF” shown in the second column of the fifth row indicates that the content presentation device 40 is in an operating state in which power is not supplied, that is, the content presenting device 40 is not operating.

When generating the analysis result information IL14, the information analysis unit 142 of the information processing device 10 uses the viewing log including the operation information of the content presentation device 40 as the first log and the communication unit included in the air purifier AR as the second log. A sensor log containing detection information is used. However, in this example, the operation information indicates the operation status according to the operation command. For example, the information analysis unit 142 refers to the linked device information, and as the linked device corresponding to the content presentation device 40 (television receiver), the air purifier in which the associated home ID (group) and the room are common. The machine AR is specified. The information analysis unit 142 reads, from the information storage unit 130, a viewing log including operation information of the content presentation device 40 and a sensor log including detection information of the air purifier AR. The information analysis unit 142 determines the number of users at the detection time from the detection information for each detection time included in the sensor log. The information analysis unit 142 counts the number of device identification information included in the detection information, and determines the counted number as the number of users. Then, the information analysis unit 142 determines the operation information indicating the operation status at the common time with the detection information. More specifically, the information analysis unit 142 determines whether or not there is time information indicating the time that matches the detection time, among the operation information included in the viewing log. When the information analysis unit 142 determines that the time information exists, the information analysis unit 142 specifies the motion information associated with the time information. When it is determined that the operation information does not exist, the information analysis unit 142 sets the operation information associated with the time information indicating the time before the detection time and having the shortest period until the detection time as the operation at that time. Specify as information.

The information analysis unit 142 may set the number of users corresponding to the operation information indicating the power OFF to 0. The number of users being 0 indicates the absence of users at that time. This is because, in such a situation, since the content presentation device 40 is not operating, the user is not contemplated for use.
The information analysis unit 142 can generate the analysis result information IL14 by associating the identified operation information, the detection information, and the group attribute information indicating the defined number of users for each time information indicating the detection time.

The information analysis unit 142 may estimate the group configuration based on the detection information included in the second log, as another example of the group attribute information of the group including the user of the content presentation device 40. The group configuration does not mean the attributes of individual users, but the characteristics of a group of which the user of the content presentation device 40 is a member. For example, the information analysis unit 142 estimates the total number of users of the content presentation device 40 as an example of the group attribute based on the detection information within the predetermined investigation period. The total number of users means the number of users that make up the group, and is different from the number of users of the first device at that time, like the number of viewers described above. If the group is a household, the total number of users corresponds to the number of household members. The information analysis unit 142 determines the maximum value of the number of users determined from the detection information on a certain day as the total number of users. The information analysis unit 142 further rounds off the average value or the median value of the maximum values of the number of users within a predetermined survey period (for example, 1 to 6 months) up to that point as the total number of users.
