  The projector 24 is a projection device that converts the image data output from the control unit 23 into image light and irradiates the image data toward the screen unit 22. For example, the projector 24 performs a display operation by individually turning on / off each tilt angle of a plurality of micromirrors arranged in an array (in the case of XGA, horizontal 1024 pixels × vertical 768 pixels) at high speed. A DLP (Digital Light Processing) (registered trademark) projector using a DMD (digital micromirror device), which is a display element that forms a light image with the reflected light, is applicable.

  The storage unit 25 is configured by an HDD (Hard Disk Drive), a nonvolatile semiconductor memory, or the like. The storage unit 25 is provided with a program storage unit 251 as shown in FIG. The program storage unit 251 includes a system program executed by the control unit 23, a processing program for executing various processes including a detection result acquisition process and a content evaluation process described later, and is necessary for the execution of these programs. Data etc. are stored.

  The storage unit 25 is provided with a content information storage unit 252. In the content information storage unit 252, content information (content data) for outputting content by the digital signage device 1 in association with a content ID for identifying the content, and a display place of the product introduced in the content The direction of the (product corner) and the time for starting the guidance of the direction of the product corner in the content (information indicating how long the content corner guidance has started since the content reproduction start) are stored. Here, the content information is composed of, for example, moving image data composed of a plurality of frame images and audio data corresponding to each frame image. In the present embodiment, the content includes guidance indicating the direction of the display location (product corner) of the product introduced in the content (see FIG. 5).

  The storage unit 25 is provided with a detection result storage unit 253. FIG. 3 is a diagram illustrating a data storage example of the detection result storage unit 253. As shown in FIG. 3, the detection result storage unit 253 includes items such as “content ID”, “measurement date / time”, “movement direction” (right direction, left direction, no movement, other directions), and the like. In association with the content ID, the detection result of the direction in which the viewer has moved after viewing the content is stored.

  The operation unit 32, the audio output unit 33, and the imaging unit 34 are connected to the control unit 23 as shown in FIG.

[Operation of Digital Signage Device 1]
Next, the operation of the digital signage apparatus 1 will be described.
FIG. 4 shows a flowchart of detection result acquisition processing executed in the digital signage apparatus 1. The detection result acquisition process is executed in cooperation with the control unit 23 and the program stored in the program storage unit 251 when the output of content is started.

  First, the control unit 23 outputs content by the projector 24 and the audio output unit 33 (step S1). For example, the control unit 23 reads the content information stored in the content information storage unit 252 according to a predetermined schedule, and the projector 24 sends the content image to the image forming unit 27 based on the moving image data of the read content information. Project (display). Further, the audio output unit 33 outputs the audio of the content based on the audio data of the read moving image data.

Next, the control unit 23 detects a viewer of the content (step S2).
For example, the control unit 23 takes a picture with the imaging unit 34 at a timing (for example, n seconds before the start of the product corner direction guidance, where n is a positive integer) immediately before the content corner direction guidance starts. Then, face recognition processing is performed on the obtained captured image. Then, a line-of-sight detection process is performed on each recognized face image to detect a line-of-sight direction, and a person whose line of sight is directed toward the image forming unit 27 is detected as a viewer. A known image processing technique can be used as the face recognition process and the line-of-sight detection process.
Alternatively, images are taken by the imaging unit 34 at predetermined time intervals from m seconds (m is a positive integer) before the start of the guidance for the location of the product corner in the content, and are recognized from the obtained captured images. Based on each face image, a person who exists for at least m seconds before the image forming unit 27 may be specified, and the specified person may be detected as a viewer.

  When the time zone for starting the guidance for the location in the direction of the product corner comes, the control unit 23 causes the projector 24 and the audio output unit 33 to output guidance for the product corner in which the product introduced in the content is displayed (step S3). ).

  FIG. 5 is a diagram showing the product corner guidance and the product corner arrangement output in step S3. For example, if the content introduces a digital camera (digital camera) and a video camera, and there is a digital camera corner on the right side and a video camera corner on the left side as shown in FIG. 5, in step S3, , An arrow indicating that the digital camera is in the right direction when viewed from the viewer and an arrow indicating that the video camera is in the left direction when viewed from the viewer are displayed. Information is provided.

  Next, the control unit 23 detects the moving direction of the content viewer (step S4). For example, the control unit 23 causes the imaging unit 34 to capture images at predetermined time intervals after starting the guidance for the product corner, recognizes the viewer detected in step S2 from each captured image, and recognizes each recognized viewing The moving direction of the viewer is detected based on the change in the position of the viewer. For example, the control unit 23 detects the moving direction of each viewer as one of four directions of “right direction”, “left direction”, “no movement”, and “other directions”. And the number of people who moved in each direction is counted. In the arrangement shown in FIG. 5, “right direction” indicates that the camera moves in a direction that coincides with the guidance of the digital camera corner. “Left direction” indicates that the camera has moved in a direction that matches the guidance at the video camera corner. “No movement” indicates that the user remains in front of the digital signage device 1 (continues to view the content). “Other direction” indicates that the content has moved in a direction different from the content guidance.

  And the control part 23 memorize | stores a detection result in the detection result memory | storage part 253 (step S5), and complete | finishes a detection result acquisition process. For example, the current date and time is acquired from the time counting unit 30, and the content ID of the content output this time, the current date and time (measurement date and time), and the number of people moved in each movement direction are associated and stored in the detection result storage unit 253.

  The control unit 23 cooperates with a program stored in the program storage unit 251 to turn off the digital signage device 1 (eg, at the end of a day) or to determine a predetermined number of data (for example, 100 cases). The content evaluation process is executed when the detection results are collected, and the effect of guiding the content to the product corner is evaluated based on the detection results stored in the detection result storage unit 253.

  In the content evaluation process, for example, the control unit 23 refers to the information stored in the detection result storage unit 253 and totals the moving direction of the viewer after viewing the content for each content. For example, for each of “right direction”, “left direction”, “no movement”, and “other directions”, the total number of people moved in that direction matches the product corner for the total number of viewers of the content. The ratio of the number of people who moved in the direction is calculated as the evaluation value of the guidance effect to the product corner of the content. For example, when content describing a digital camera and a video camera is output in the arrangement shown in FIG. 5, the higher the percentage of viewers that move in the direction that matches the arrow indicating the direction of the digital camera corner, that is, the right direction. The higher the percentage of people, the higher the effect of guiding the content to the digital camera corner. The higher the percentage of viewers who moved in the direction that matches the arrow indicating the direction of the video camera corner, that is, the higher the percentage of people who moved to the left, the higher the effect of guiding the content to the video camera corner. Indicates. Note that the number of viewers who do not move does not indicate the effect of guiding to the product corner, but may be an evaluation value indicating the effect of attracting customers of the content because it is the number of viewers who continue to view the content.

  Note that the movement direction of the viewer may be aggregated for each measurement time period. Thereby, the guidance effect to the product corner of the contents can be evaluated for each time zone.

  Further, when detecting a viewer in step S2, a known gender / age estimation process is performed on each face image recognized in the face recognition process to obtain the gender / age (age) of each viewer, When the moving direction of each viewer is detected in S4 and the number of people moving in each direction is counted, the number of viewers moving in each direction is counted for each gender and age, and the detection result storage unit 253 is counted. It is good also as making it memorize. In the content evaluation process, the moving direction of the viewer after viewing the content may be aggregated for each content by gender and age. For example, for each of “Right”, “Left”, “No movement”, and “Other directions”, the total number of people by gender / age is summed, and all viewers of that gender / age are classified by gender / age. The ratio of the number of people who moved in that direction to the number of people may be calculated as the evaluation value. Thereby, the guidance effect to a goods corner can be evaluated according to sex and age. In addition, for each content, the moving direction of the viewer after viewing the content may be aggregated by sex and age by time zone. Thereby, it is possible to evaluate the induction effect by time zone, sex, and age to the product corner of the content. Further, it is possible to grasp which customer moves to which product corner at which time zone.

As described above, according to the digital signage apparatus 1, the control unit 23 detects the content viewer based on the captured image acquired by the imaging unit 34, and determines the moving direction of the viewer after viewing the content. The content is detected and the content is evaluated based on the detected moving direction of the viewer. For example, the control unit 23 evaluates the content based on whether or not the direction guided by the content matches the moving direction of the viewer.
Therefore, it is possible to evaluate the content induction effect.

  For example, the content includes information indicating the direction of the display location of the product introduced in the content, and the control unit 23 determines whether the direction of the display location of the product indicated by the content matches the moving direction of the viewer. Based on whether or not, the content is evaluated. Therefore, it is possible to evaluate the effect of guiding the content product to the display location.

  In addition, the description content in the said embodiment is a suitable example of the digital signage apparatus 1 which concerns on this invention, and is not limited to this.

  For example, in the above embodiment, the case where content introducing two products of digital camera and video is evaluated has been described as an example. However, one product may be introduced by content. In this case, it can be evaluated that the higher the ratio of the number of viewers who moved in the direction that matches the arrow indicating the product corner of the product introduced in the content, the higher the effect of guiding the content to the product corner. .

It also displays content that introduces multiple products, and then determines which product the viewer has moved in the direction that matches the arrow that indicates the product corner of the product that was introduced in the content. It may be evaluated whether the advertising effect is high.
In the above embodiment, the case where the guidance effect of the content introducing the product is evaluated has been described as an example. However, the present invention is not limited to this. For example, the content introducing the event (the direction of the venue of the event is guided). The present invention may be applied to the evaluation of the induction effect of the content including the content.

  Moreover, although the digital signage apparatus 1 in the said embodiment demonstrated as what displays an image by projecting an image on a screen from a projector, it assumes that it has other display apparatuses, such as a liquid crystal display and a plasma display, for example. Also good.

  In addition, the detailed configuration and detailed operation of the digital signage apparatus can be changed as appropriate without departing from the spirit of the invention.
