The “location characteristic” is statistical data of attribute information at the location that defines the characteristics of an unspecified number of passers-by who see the street display 20 placed on the street, for example, gender, age, and Consists of the most interesting topics such as sports, fashion and movies.

  The location characteristic measurement unit 101 includes a transmission / reception unit 103, a terminal position acquisition unit 104, an attribute acquisition unit 105, a memory 106, a movement direction calculation unit 107, a viewability calculation unit 108, a most frequent direction calculation unit 109, and a viewing target characteristic recording unit. 110.

  Here, an example will be given regarding the contents of data stored in the location characteristic storage unit 130 and the content storage unit 120.

  FIG. 4 is an example of data stored in the location characteristic accumulation unit according to the embodiment of the present invention.

  The location characteristic storage unit 130 stores the result of the location characteristic analysis unit 102 defining the typical characteristics of passersby in the time zone “001” at the location ID “0001”, for example. As described above, the place characteristic storage unit 130 stores the place ID, measurement time, time zone information, the place, the place characteristic measured in the time zone, and the like. Here, the “location ID” is a number uniquely assigned to a certain location and may correspond to each street display 20 or may correspond to a certain area. “Time zone information” represents a time zone classification such as morning, noon, and night.

  The location characteristic storage unit 130 stores a typical property for the new location ID defined by the location analysis unit 102 and the latest typical property for the existing location.

  The content storage unit 120 stores video / audio itself such as advertisement content, its content ID, and basic information about the content. As basic information, for example, in the case of advertising content, information about a product to be advertised and attributes of people to be watched, that is, sex, age, and topics of interest are stored. This basic information overlaps at least partly with information stored in the location characteristic storage unit 130, such as sex, age, and topic of interest.

  In addition, the location characteristic measurement unit 101 of the apparatus 100 of FIG. 3 has a configuration in which each street display 20 is locally provided and a configuration in which one is provided for a plurality of street displays 20. The example which changed the deployment form is shown in FIG. FIG. 5 shows another example of the configuration of the location characteristic measurement unit according to the embodiment of the present invention. The example in the figure is an example in which only the transmission / reception unit 103 is provided for each street display, and other functions are connected via the network 30.

  The present invention can be applied to any of the configurations shown in FIGS.

  Hereinafter, the operation of the location characteristic measurement unit 101 will be described.

  FIG. 6 is a flowchart of the operation of the location characteristic measurement unit in one embodiment of the present invention.

  Step 110) The transmission / reception unit 103 receives the terminal ID, the terminal position information, and the terminal position measurement time automatically transmitted from the mobile terminal 10 directly or via a network. The received information is recorded in the memory 106 as shown in FIG. The processing of the terminal position acquisition unit 104 will be described below. FIG. 8 is a flowchart of the operation of the transmission / reception unit / terminal position acquisition unit according to the embodiment of the present invention. When the terminal ID, the position information, and the position measurement time are sent from the mobile terminal 10 (step 1101, Yes), the transmission / reception unit 103 receives the information (step 1102), and the terminal ID received by the transmission / reception unit 103 The position information and the position measurement time are passed to the terminal position acquisition unit 104 (step 1103). The terminal location acquisition unit 104 records the passed terminal ID, location information, and location measurement time in the memory 106 (step 1104).

  Step 120) The movement direction calculation unit 107 issues a position information transmission request to the memory 106, thereby acquiring the terminal ID, the terminal position information, and the terminal position measurement time, and moves for each terminal ID of each mobile terminal 10. The direction is calculated, and a set of the terminal ID and the moving direction is passed to the viewability calculation unit 108.

  Step 130) The viewability calculation unit 108 uses the street display direction and the moving direction stored in the street display direction recording unit 111, and a person carrying the mobile terminal for each terminal ID uses the street display 20 to move. Determine whether viewing is possible. The viewability calculation unit 108 may record the viewability determination result for each portable terminal ID in the view target characteristic recording unit 110. In the following description, it is assumed that the viewability determination result is recorded.

  Step 140) The location characteristic analysis unit 102 performs a statistical process of the attribute information of the terminal ID that can view the street display 20 recorded in the viewing target characteristic recording unit 110.

  The process of step 140 is executed when the number of terminal IDs determined to be viewable in step 130 reaches a predetermined number or more, or at a certain time after a predetermined period has elapsed. You may do it.

  At the time of statistical processing, the mobile terminal 10 transmits information indicating the gender, age, and field of interest of the mobile terminal holder together with the terminal ID to the transmission / reception unit 103 and is stored in the memory 106 by the attribute acquisition unit 105. In this case, the terminal ID capable of viewing the street display 20 is acquired from the viewing target characteristic storage unit 110, and further information indicating the gender, age, and the field of interest corresponding to the terminal ID capable of viewing the street display 20 is stored in the memory 106. There is also a method of obtaining statistical data from The result of the statistical processing is stored in the location characteristic accumulation unit 130 shown in FIG. The data of the location characteristic storage unit 130 shown in FIG. 4 is an example in the case where the location ID is assigned to each street display 20 and the number of terminal IDs determined to be able to view this street display 20 is four. In the figure, “time zone” is information indicating in which time zone the measurement time is included by dividing the time of the day into one or more time zones in advance. In “gender”, for example, males are coded as “0” and females are coded as “1” and recorded. In “age”, the age is divided into one or more ages in advance, and information indicating in which era the age information associated with the terminal ID is included is recorded. . For “interest”, several areas of interest are determined in advance, and code numbers indicating each area are also determined in advance (eg, 0 is for sports, 1 is for music, 3 is for fashion) The number of the field containing the information indicating the field of interest transmitted based on the terminal ID is recorded.

  The location characteristic analysis unit 102 calculates, as statistical information, for example, a field of interest in which the percentage of women is the highest among those who can view the street display 20 in the time zone “001”. However, the attribute information as described above can be acquired only when the mobile terminal 10 discloses the attribute information. For example, in the morning at location “001”, there are many men in their 30s who are interested in housing information and sports, but there are many women in their 30s and 20s in the daytime. It is possible to define many characteristics for people who pass there by time, such as being interested in information about the car, the latter being interested in cars and gourmets. At this time, only the information stored in the viewing target characteristic storage unit 110 can be used for the calculation of the location characteristic based on the viewing possibility determination performed in step 130. Thus, by summing up the time zone and the obtained attribute information, the location characteristics of the time zone are defined. As a method of aggregation, simply select the most common attribute elements, or specify the most frequent only by gender and age group, and select the attributes that such people are most interested in. An aggregation method that takes into account co-occurrence between elements, such as defining as a typical attribute, may be used.

  Step 150) The location characteristic storage unit 130 is updated with the location characteristics in a certain time zone defined by the location characteristic analysis unit 102 in Step 140.

  Further, between the step 130 and the step 140, the mode (mode) in which the mobile terminal 10 is moving most frequently using the moving direction obtained in the step 130 by the mode calculating unit 109 is, for example, Alternatively, a process of calculating for each predetermined time zone and recording the time zone and the most frequent direction in association with each other in the viewing target characteristic recording unit 110 may be inserted. For this, the correspondence of the movement purpose considered from the combination of the movement direction and the time zone registered in the most frequent direction calculation unit 109 in advance is used. For example, if there are many people who move in the direction toward the station in the morning in a place called a passage toward the station, it can be estimated that the purpose of movement is often commuting to school. At the same time, business-related content can be preferentially added to the playlist. That is, the mode calculation unit 109 refers to the basic information for the content stored in the content storage unit 120 based on the correspondence with the movement purpose, thereby giving the content selection unit 121 the priority of the content related to the movement purpose. Can be raised.

  Step 160) The content selection unit 121 calculates the degree of matching between the location identification referred from the location characteristic accumulation unit 130 and the viewing target attribute of the content referenced from the content accumulation unit 120. A process of adding the most suitable content to the playlist on the street display 20 may be performed. This will be described with reference to the flowchart of FIG.

  FIG. 9 is a flowchart of the operation of the content selection unit in one embodiment of the present invention.

  Step 310) Upon receiving a playlist generation assistance request from a street display of a certain place, for example, the place “001”, the content selection unit 121 acquires the place characteristic corresponding to the place “001” from the place characteristic accumulation unit 130. .

  Step 320) For content candidates that may be displayed on the street display 20, the content ID and the corresponding viewing target attribute are acquired from the content storage unit 120. As described above, the viewing target attribute is, for example, information about the age group and sex of the viewer targeted by the content, and what topic the user is interested in.

  Step 330) The degree of matching between the location characteristic acquired in Step 310 and the viewing target attribute is calculated and scored. As the calculation of the fitness level, for example, for each candidate content, 12 points are added for the location identification, gender, age, and the three topics that are interesting, and 4 points are added for each element by partial match. An addition method or a method of weighting and adding any important element can be considered. In addition, when the fitness score has already been calculated for a certain factor in another system, the fitness can be defined in consideration of more factors by adding the score for this system to that score. .

  Step 340) Prioritize the contents according to the high score of fitness. For example, higher priority may be set for content with higher scores as content to be added to the playlist.

  Step 170) The content selection unit 121 determines whether there is a street display (distribution destination candidate) whose fitness is not calculated among the street displays (distribution destination candidates) whose content suitability is to be calculated. If there is a calculated street display, the process returns to step 160. If there is no street display whose fitness is not calculated, the process ends.

  As a method for specifying the street display whose fitness is to be calculated, a location ID is assigned to each street display, and a list of location IDs corresponding to the street display whose fitness is to be calculated is stored in a storage unit (not shown). And the content selection unit 121 obtains this list from the storage unit at the time when the step 160 is started. In addition, as a method of determining whether or not there is a street display whose fitness is not calculated, a flag indicating whether or not each street display has been processed is provided, and the content selection unit 121 sets all flags at the time of list acquisition. There is a method in which a predetermined value indicating unprocessed is set and a flag value for a street display subjected to the processing of step 160 is set to a predetermined value indicating processed.

  Next, the viewability determination process in steps 120 and 130 of the flowchart of FIG. 6 will be described in detail.

  FIG. 10 is a flowchart of viewing possibility determination processing according to the embodiment of the present invention.

  Step 1201) The movement direction measuring unit 107 of the place characteristic measuring unit 101 determines whether or not a predetermined viewing possibility determination processing time has come. In addition to the method of determining the viewability determination processing time, the previous viewability determination processing time is recorded in a recording unit (not shown), and the time is a predetermined length from the previous determination processing time. It is possible to determine whether or not elapses, and when a predetermined time elapses, the process may proceed to step 1202.

  Step 1202) The movement direction calculation unit 107 determines whether or not there is an unprocessed terminal ID among the terminal IDs recorded in the memory 106. If all terminal IDs have been processed, the movement direction calculation unit 107 ends the process. If there is an unprocessed terminal ID, the process proceeds to step 1203.

  In addition, as a method for determining whether or not the terminal ID is unprocessed, for example, a flag indicating whether or not processing has been performed for each terminal ID is provided, and flag values for all terminal IDs are set to “ By setting it to “predetermined value indicating unprocessed” and setting the flag value for the selected terminal ID to “predetermined value indicating processed” every time a terminal ID is selected. There is a method of determining whether the value of the flag for each terminal ID is a predetermined value indicating unprocessed or a value indicating processed.

  Step 1203) The movement direction calculation unit 107 selects one terminal ID from the unprocessed terminal IDs in the memory 106, and proceeds to Step 1204.

  Step 1204) The movement direction calculation unit 107 acquires the position measurement result and measurement time information of the selected terminal ID from the memory, and proceeds to Step 1205.

  Step 1205) The movement direction calculation unit 107 calculates a direction vector from the measurement position at the measurement time farthest from the current time to the position measurement position at the measurement time closest to the current time, and the direction of the calculated direction vector Is set as the moving direction of the selected terminal ID, and the moving direction calculation unit 107 transfers the terminal ID and the moving direction information to the viewability calculation unit 108 and proceeds to step 1301.

  Step 1301) The viewability calculation unit 108 reads the predetermined display screen direction of the street display 20 and the predetermined threshold angle from the street display direction storage unit 111, and determines the moving direction of the selected terminal ID. An angle formed by the direction of the display surface of the read street display 20 is calculated, and it is determined whether or not the formed angle is equal to or smaller than the read threshold angle (if there are a plurality of street displays, the location is determined for each street display. An ID is assigned and the location ID and the display direction of the display are associated with each other and recorded in the street display direction viewing target characteristic recording unit 111, and the terminal position acquisition unit 104 sends the terminal ID together with the location ID information from the transmission / reception unit 103. The ID, terminal position information, and terminal position measurement time are received and recorded in the memory 106 in association with each other. Place may be that the location characteristic measurement unit 101 performs processing shown in FIG. 10 for each location ID). If it is equal to or smaller than the threshold value, the process proceeds to step 1302. If it is not less than or equal to the threshold, the process proceeds to step 1303.

  Step 1302) The viewability calculation unit 108 makes the selected terminal ID viewable on the street display, and returns to Step 1201. Note that the viewability calculation unit 108 may record the determination result in the viewing target characteristic recording unit 110 (in this case, the terminal ID and information indicating that viewing is possible are associated with each other in the viewing target characteristic recording unit 110). May be recorded).
