If it is determined that these conditions are met, the advertisement displayed on the display unit is in Japanese. The contents of these items are stored in advance.

  If there are a plurality of countries that satisfy these conditions, display language candidates may be displayed on the display unit and selected by the viewer.

  FIG. 7 is a diagram illustrating an example of the tracking database 2013. The tracking database 2013 is a database that stores a result of tracking an advertisement in which the viewer's viewpoint is displayed on the display unit. As shown in FIG. 7, the tracking database 2013 includes a serial number for identifying the viewer's viewpoint being tracked, a branch number for identifying an advertisement viewed by the tracking, and the start of tracking (start). ) Time, tracking end (end) time, the number of the advertisement being tracked, and the viewing percentage that indicates how far the displayed advertisement is viewed are associated with each display device. Is remembered. Although not shown in FIG. 7, actually, detailed data (data in which time is associated with the position of the viewpoint on the image being tracked) indicating when and at which position the viewpoint is stored is stored. Yes. In the following, the degree to which the advertisement is being viewed is shown as a percentage, but the degree may be determined by the amount such as the number of rows and the time.

  In FIG. 7, for example, the time when the advertisement identified by the content number C0001-01 is viewed is from 18:00 on July 1, 2014 to 18:02 on July 1, 2014. 80% (for example, 80 characters of the text advertisement shown in FIG. 4) are viewed. The time when the advertisement identified by the content number C0001-02 is viewed is from 18:02 on July 1, 2014 to 18:03 on July 1, 2014, and is 100% of the total ( For example, the company logo image shown in FIG. 4 is viewed. The tracking database 2013 stores the content of each item described above for each display device (display device X0001 in FIG. 7). These contents are recorded by a tracking unit 203 described later.

  FIG. 8 is a diagram illustrating an example of the display status database 2014. The display status database 2014 is a database that stores the display status of advertisements. As shown in FIG. 8, the display status database 2014 identifies a serial number for identifying a display device, a display device installation location, location information on the installation location, and an advertisement displayed on the display device. , The tracking start (start) time, the tracking end (end) time, and the viewing ratio are stored in association with each other.

  In FIG. 8, for example, the display device identified by X0001 is installed at a certain position (first) of the Shinagawa station concourse, and the position is P1. The display device displays an advertisement identified by C00001-01, and indicates that the advertisement was tracked from the start time to the end time described above, and the viewing ratio was 80%. The start time, end time, and viewing ratio are the same as those shown in FIG. 7, and are recorded by the tracking unit 203 described later. The contents of items other than these are stored in advance.

  FIG. 9 is a diagram illustrating an example of the facial expression database 2015. The facial expression database 2015 is a database for determining the degree of interest in the advertisement from the viewer's facial expression. As shown in FIG. 9, the facial expression database 2015 includes a serial number for identifying the viewpoint of the viewer being tracked, the attributes (gender, age, height, physique) of the viewer being tracked, and the viewer. Are stored in association with each other, the degree of interest in the advertisement, and the timing at which the value indicated by the degree of smile and the degree of interest is generated.

  In FIG. 9, for example, tracking identified by T0001 is performed by a 30-year-old female, 160 cm tall, and medium-sized viewer, and the timing is A in the range in which the advertisement is viewed. Sometimes the smile level has increased slightly, indicating that the level of interest has increased. The tracking identified by T0002 is by a 40-year-old man, a height of 180 cm, and a thin physique. When the advertisement viewing timing is A, the smile level is normal and the interest level is Indicates that has become slightly larger.

  The viewer attribute can be determined by, for example, analyzing the image captured by the imaging unit 102 of the display device 100 by the recognition unit 202 of the server 200. In addition, the smile level can be determined, for example, based on how much the viewer's mouth corner is raised by analyzing the above-described image by the recognition unit 202. That is, it can be determined that the viewer is smiling as the mouth corner is raised. Furthermore, the degree of interest is determined by, for example, how much the viewer is interested in the advertisement when the tracking unit 203 determines the size of the pupil of the viewer's eyes and the number of blinks. You can judge whether you have it. That is, it can be determined that the larger the pupil and the greater the number of blinks, the more viewers are watching the advertisement with interest. Next, returning to FIG. 1, each unit after the recognition unit 202 will be described.

  The recognition unit 202 analyzes the image received from the display device 100 to detect the viewer, and recognizes the viewer's attributes. Various techniques conventionally known can be applied to the analysis of the viewer. The tracking unit 203 analyzes the image received from the display device 100 and the viewpoint on the viewer's image detected by the detection unit 103, and tracks the viewer's viewpoint on the image. The display control unit 204 displays an advertisement on the display device 100 and switches the display language of the advertisement. The totaling unit 205 totals the results of tracking the viewer's line of sight. The communication unit 206 receives the image captured by the imaging unit 102 in real time, and communicates various information between the server 200 and the display device 100. Specific processing performed by each unit of the display device 100 and the server 200 will be described later with reference to flowcharts.

  FIG. 10 is a flowchart showing a processing procedure of processing (information collection processing) for collecting information for evaluating the advertising effect displayed on the display device 100 by the system.

  As illustrated in FIG. 10, in the information collection process, the detection unit 102 detects the viewer from the images captured by the imaging unit 101 of the display device 100, and the result (for example, the position of the viewpoint on the image) along with the image. To the server 200, and the recognition unit 202 detects and recognizes the viewpoint of the viewer in the image (S1001).

  For example, the recognition unit 202 compares the pixel value on the detected and recognized image with the appearance pattern of the viewer stored in the language switching database 2012 shown in FIG. Determination is made (S1002).

  The display control unit 204 calls up the content stored in the language determined by the recognition unit 202 from the content database and displays the content on the display unit 101 of the display device 100 (S1003).

  The tracking unit 203 repeatedly reads the viewer's viewpoint on the image recognized by the recognition unit 202 for each viewer's viewpoint, and records the tracking result in the tracking database 2013 (S1004, S1005, S1006). For example, the tracking unit 203 specifies the serial number and branch number shown in FIG. 7 in order to identify the viewer's viewpoint recognized by the recognition unit 202, and records the start time of tracking the advertisement from that viewpoint. To start. The tracking unit 203 reads the viewer's viewpoint on the image recognized by the repetitive recognition unit 202, and for each advertisement stored in the content database 2011 shown in FIG. And the display amount of the content database 2011 are compared to determine the viewing ratio, and the result is recorded in the tracking database 2013.

  Furthermore, the tracking unit 203 analyzes the image recognized by the recognition unit 202, determines the smile level and the interest level of the viewer who is tracking, and records the result in the display status database 2014 (S1007, S1008). For example, the tracking unit 203 analyzes the above-described image, obtains the smile level and the interest level based on the degree of increase in the viewer's mouth corner, the size of the pupil of the viewer's eyes, and the number of blinks. The result is recorded in the display status database 2014 together with the gender, age, height, and physique that are part of the attribute. At this time, the tracking unit 203 records the timing at which the smile level and the interest level are generated in the display status database 2014 together with these pieces of information.

  Then, the recognition unit 202 determines whether or not the viewer's viewpoint in the image can no longer be detected and recognized (S1009), and determines that the viewer's viewpoint in the image cannot be detected and recognized (S1009; Yes), the process ends. That is, the above process is repeated until the viewer's viewpoint in the image cannot be detected or recognized. When the process of step S1009 ends, the information collection process shown in FIG. 10 ends.

  FIG. 11 is a flowchart illustrating a processing procedure of a process of collecting information collected by the above-described information collection process (information aggregation process). Note that the tracking database 2013 and the display status database 2014 are updated at any time in the above-described information collection process, and therefore this process can be executed at an arbitrary timing by a system administrator or the like.

  As shown in FIG. 11, in the information totaling process, the totaling unit 205 refers to the tracking database 2013 and totals the number of tracking for each advertisement type (S1101). For example, in FIG. 7, the totaling unit 205 counts one for the advertisement with the advertisement number “C0001-01” and two for the advertisement with the advertisement number “C0001-02”, and totals the number. For example, the total number of tracking can be visually grasped by the totaling unit 205 by creating a graph as shown in the left of FIG. 12 and displaying it on the display unit. , Which ads are often watched.

  Furthermore, the totaling unit 205 refers to the tracking database 2013 and totals the viewing ratio for each advertisement type (S1102). For example, in FIG. 7, the counting unit 205 views 80% of the text advertisement identified by the advertisement number “C0001-01”, but the text identified by the same advertisement number “C0001-01” is also available. Read the viewing percentage of the ad. The viewing ratio read in this way is such that, for example, the totaling unit 205 creates a graph as shown in the right of FIG. 12 and displays it on the display unit, thereby visually grasping how far the advertisement has been viewed. And know which advertisements have been viewed to the end. The example shown on the right side of FIG. 12 indicates that the largest number of people watched up to 80% of the text advertisement identified by “C0001-01”. Therefore, the remaining 20% of the text advertisement may be viewed at a low rate for some reason (for example, there are too many characters to read quickly until the end, or the content is not interesting). Recognize.

  Then, the counting unit 205 accesses the content database 2011, the tracking database 2013, and the display status database 2014 using the serial number and branch number of the tracking database 2013 as a key, and for each display device 100 installed at each installation location, Are counted (S1103). For example, the tabulation unit 205 tabulates the number of tracking of advertisements (text advertisements and company logo advertisements) for the product A identified by the advertisement numbers “C0001-01” and “C0001-02” for each store. A store summary table as shown in Fig. 2 is created and displayed on the display unit. In FIG. 13, the results of aggregation are stored for each month, and the transition of the advertisement being viewed can be grasped by obtaining the month-on-month ratio.

  In addition, the counting unit 205 refers to the facial expression database 2015 shown in FIG. 9 to determine which advertisement makes the viewer smile for each age and sex of the viewer's facial expression and interest level when tracked. You may total whether it was watched with interest from the viewer. For example, the tabulation unit 205 ranks by age and gender in descending order of the number of interests and smiles “Large”, and at what timing the level of interest and smiles is “Large”. Judge whether it became. Then, the totaling unit 205 may identify words and images in the advertisement that makes the viewer do so, and may total the number of words and images that have caused the viewing to be in such a state. By performing such aggregation, it is possible to evaluate what kind of words and images have influenced the viewer at what timing. Of course, when the viewer becomes indifferent and indifferent, the same judgment can be made and tabulated.

  As described above, in this system, by executing the information collection process and the information aggregation process described above, the number of advertisements to be viewed, which advertisements the viewers watched with interest, and at what timing It is possible to evaluate the advertising effect on the viewer in detail, such as whether they are interested.

  In the above embodiment, the tracking unit 203 refers to the tracking database 2013 to determine whether or not tracking is repeated around a certain time, and when it is determined that tracking is repeated, the display control unit 204 may determine that the advertisement displayed in the portion is difficult to view or is viewed with particular interest, and may enlarge and display the portion of the advertisement at a certain magnification. For example, the tracking unit 203 determines the position of the viewpoint on the image being tracked when the end time does not change for a certain time and the viewing rate does not change for a certain time, or in a certain time zone from the start time to the end time. If there is no change, the advertisement is enlarged and displayed according to the above determination. At this time, the enlargement ratio may be increased as the number of times tracking is repeated.

  Further, as shown in FIG. 8, in this system, the display status of advertisements by the display device 100 is recorded for each installation location. Therefore, for example, a beacon or BLE (Bluetooth (registered)) is established between a portable terminal owned by a viewer and a terminal communication unit 105 of a certain display device 100 (for example, the display device 100 installed in the Shinagawa station concourse 1). When the tracking unit 203 records in the tracking database 2013 and the display status database 2014, the terminal ID of the portable terminal is recorded in association with the serial number and the branch number. The tracking unit 203 of the display device 100 (for example, the display device 100 installed in the Shinagawa station concourse 2) refers to the tracking database 2013 and the display status database 2014 using the terminal ID, serial number, and branch number as keys, Which ads the viewers who own the mobile device watched, and the viewing percentage of those ads And the subsequent advertisement may be displayed on the display unit.

  In the example shown in FIGS. 7 and 8, the text advertisement identified by the advertisement number “C0001-01” of the record (serial number and branch number “T0001-01”) in which a certain viewer shows the tracking record is 80% at present. When another viewer detects the viewer's mobile terminal by the above-described method, the serial number and branch number recorded in association with the terminal ID of the mobile terminal are used as keys. The advertisement number that the viewer is viewing is specified, and the remaining 20% of the text advertisement that is a continuation of the advertisement with the specified advertisement number is displayed on the display unit. In this way, by displaying the continuation of the currently viewed advertisement from one display device 100 to another display device 100, the viewer can continuously view the same advertisement while moving from place to place. In addition, the advertiser can guide the viewer to a place where the display device 100 is installed by an advertisement continuously displayed on different display devices 100.

  In the above-described example, the advertisement is displayed by obtaining the viewer's viewing ratio. However, the tracking unit 203 measures the display time of the advertisement so far (for example, 10 seconds out of 30 seconds). For example, the continuation of the advertisement (for example, the remaining 20 seconds out of 30 seconds) may be displayed on another display device 100 by determining the elapsed time and remaining time when the advertisement is viewed.

  In the above-described example, when the display device 100 displays content, the display language of the content is determined by the appearance pattern of the viewer. However, if it is known in advance that there are many viewers of a specific nationality depending on the area where the display device 100 is installed, and the viewer is analyzed and corresponds to a plurality of display languages, the language of the nationality with many viewers The content may be displayed with. Furthermore, it is possible to switch the content to be displayed on the display device 100 at any time according to the marketing information in that region.

  For example, when a supermarket in a region where the display device 100 is installed displays advertisements for a plurality of products (for example, advertisements for the products A and B), an advertisement for a product with a high sales amount or a large sales volume in the supermarket. May be displayed on the display device 100 and the advertisement to be displayed may be switched every month by increasing or decreasing these values. Further, the advertisement time of a product with a high sales amount or a large sales quantity may be extended.

  Furthermore, movement information (for example, information that associates the terminal ID and electronic medium ID with the Tokyo-Shinagawa boarding / exiting record and the date and time) recorded on an electronic medium such as a viewer's mobile terminal or IC commuter pass is included. When accumulated in the database, the counting unit 305 refers to the tracking database 2013, the display status database 2014, and the movement information thereof, and when the product is purchased before a predetermined time has passed since viewing, It may be determined that the product has been purchased by the viewer viewing the advertisement.

  For example, the counting unit 205 records the terminal ID and electronic medium ID, the purchased product, the purchase location, and the purchase date and time using the terminal ID and electronic medium ID included in the movement information as keys. Referring to the database, the viewer who possesses the terminal ID or electronic medium ID purchased the product after how long it has passed from the boarding date / time recorded as the movement information to the purchase date / time of the product. Determine whether. This database stores information when products are purchased with electronic money recorded on mobile terminals or electronic media at station shops, convenience stores, etc. For example, the period from the boarding date to the purchase date Is one day, the counting unit 205 can determine that the product has been purchased by viewing the advertisement of the product.

  Furthermore, if the purchase is made within a certain range (for example, a store in the same station as the station where the display device 100 is installed) from the display device 100 on which the advertisement of the product is displayed within that period, the advertisement It may be determined that there is a high possibility that the product has been purchased by viewing.

  As described above, according to the present system, the relationship between the viewer and the advertisement is multifaceted by using not only the advertisement effect but also the peripheral data such as the movement information of the viewer and the purchase history of the product. It can be a material for analysis.
