Therefore, in the present embodiment, a computer program for functioning as those modules (a program for causing a computer to execute each procedure, a program for causing a computer to function as each means, a function for each computer) Also serves as a description of a program, system and method for realizing However, for convenience of explanation, "store", "store", and equivalent terms are used, but in the case where the embodiment is a computer program, these terms are stored in a storage device or stored. It means to control to be stored in the device. Also, modules may correspond to functions one to one, but in mounting, one module may be configured by one program, or a plurality of modules may be configured by one program, and conversely one module May be composed of a plurality of programs. Also, multiple modules may be executed by one computer, or one module may be executed by multiple computers in a distributed or parallel environment. Note that one module may include another module. Also, in the following, “connection” is used not only for physical connection but also for logical connection (transfer of data, instruction, reference relationship between data, login, etc.). The "predetermined" means that it is determined before the target processing, and of course after the processing according to the present embodiment has started, before the processing according to the present embodiment starts. Also, before the target processing, it is used according to the current situation and condition, or including the meaning of being determined according to the current situation and condition. When there are a plurality of "predetermined values", they may be different values, or two or more values (of course, all the values are also included) may be the same. In addition, the description “to perform B if A” is used in the meaning of “determining whether or not A and performing B when it is determined to be A”. However, the case where determination of whether it is A or not is unnecessary is excluded. Moreover, when things are listed like "A, B, C" etc., it is an illustration list unless there is a notice, and the case where only one of them is selected (for example, only A) is included.

The user operation field 550 stores user operations (icon movement, display content change instruction, etc.).

The user detection module 112 includes a portable terminal connection state management module 114 and a front user detection module 116.
The portable terminal connection state management module 114 manages the connection state of the portable terminal 150. The initial user determination (connection confirmation in a predetermined period) and the information management (unoperated state etc.) of the connected portable terminal 150 are performed.
The front user detection module 116 recognizes the portable terminal 150 in the communicable range of the front of the digital signage 100 or the operator of the portable terminal 150.
The “communicable range” here is a range determined by the direction or the number of WiGig antennas 120 of the wireless communication of IEEE 802.11ad. A plurality of WiGig antennas 120 included in the digital signage 100 may be provided.

Also, the WiGig control module 108 may transmit a beacon signal. In that case, the WiGig antenna 120 may recognize the number of recognizable mobile terminals or the number of operators according to the number of mobile terminals 150 that have responded to the beacon signal. Here, the number of operators may be the number of people operating the portable terminal 150 (that is, the same as the number of portable terminals 150), or a portable terminal among the users 210 of the portable terminal 150 that responded to the beacon signal. The number of users registered in the information management server 180 may be used.

  The signage information storage module 118 stores content information to be displayed by the display module 102, screen information to be displayed on the portable terminal 150, advertisement information to be distributed to the portable terminal 150, and other data. When the data managed by the signage information storage module 118 is managed by an external network storage (for example, the signage data management server 170), the signage information storage module 118 is unnecessary. The signage information storage module 118 stores, for example, a content information table 300. FIG. 3 is an explanatory view showing an example of the data structure of the content information table 300. As shown in FIG. The content information table 300 includes a content ID column 310, a content information column 320, a screen information column 330 for mobile terminals, and an attribute information column 340.

The portable terminal information management server 180 has a user information search module 182 and a user information storage module 184.
The user information search module 182 searches for user information registered in the user information storage module 184 from the portable terminal ID transmitted from the digital signage 100.
The user information storage module 184 stores and manages, as user information, a portable terminal ID, a use history of the digital signage 100 so far, and the like. User registration is performed on the portable terminal information management server 180 in advance using a web service or the like according to the operation of the user.
The portable terminal information management server 180 can be used for collecting and managing user information, an authentication processing function, and the like, but this is not necessarily required in the present embodiment.
The user information storage module 184 stores, for example, a user information table 600. FIG. 6 is an explanatory view showing an example of the data structure of the user information table 600. As shown in FIG. The user information table 600 includes a portable terminal ID field 610, a user ID field 620, a name field 630, an age field 640, a sex field 650, and the like. The portable terminal ID column 610 stores a portable terminal ID. The user ID column 620 stores the user ID of the user 210 who holds the portable terminal 150 of the portable terminal ID.

In addition, attributes (hobby, purchase history, usage history of the digital signage 100, and the like) for selecting content to be presented by the digital signage 100 may be stored.

The digital signage 100, the portable terminal 150, the signage data management server 170, and the portable terminal information management server 180 are connected to one another via the communication line 190. Communication between the digital signage 100 and the portable terminal 150 is wireless communication in accordance with IEEE 802.11ad.
The communication line 190 may be wireless, wired, or a combination of these, and may be, for example, the Internet as a communication infrastructure, an intranet, or the like. A mobile phone line is used to connect the mobile terminal 150 and the communication line 190. Also, the functions of the signage data management server 170 and the portable terminal information management server 180 may be realized as a cloud service.

FIG. 2 is an explanatory view showing an example of a scene in which the present embodiment is used.
For example, the digital signage 100 is installed on a sidewalk or the like through which the user 210 passes. In the digital signage 100, advertisements (still images, moving images) are presented on a large display. Of course, the speaker may output audio such as music. There are a user 210 who is interested in the advertisement and a user 210 who is passed without being shown interest. The user 210 has a portable terminal 150.
It can be said that the user 210 (mobile terminal 150) in the front area 250 of the digital signage 100 is interested in the advertisement. Specifically, the user 210A (mobile terminal 150A) and the user 210B (mobile terminal 150B). On the other hand, it can be said that the user 210D on the back of the digital signage 100 and the user 210C who has passed off the front area 250 are not interested in the advertisement.

In the present embodiment, for example, the following processing is performed. In particular, this explanation (the explanation in this paragraph number) is intended to facilitate the understanding of the present embodiment, and is not intended to be interpreted in a limited manner using this explanation. And it should not be judged that the invention to be patented is the one described in the detailed description of the invention (Patent Law Article 36 Section 6 No. 1) using only this explanation part. It is natural.
The identification information transmitted from the portable terminal 150 present in the front area 250 of the digital signage 100 is received. Then, the portable terminal 150 temporarily occupies the digital signage 100. An operation for remotely controlling the digital signage 100 is accepted. For example, according to the operation data in the portable terminal 150, the display content of the content in the digital signage 100 is changed.
If there are a plurality of people around the digital signage 100, they pass, and even people who are not behind the digital signage 100 and so forth (people who do not look at the digital signage 100) are detected. Therefore, only the person in front of the digital signage 100 is detected by using the directivity of WiGig (beamforming: a technology of narrowing radio waves and emitting intensively in a specific direction).
By remote control of the digital signage 100 at the operation of the user 210, occupation of the digital signage 100 occurs. However, even though the user 210 is not already in the front area 250 of the digital signage 100, the other person can not use it if it is occupied. Therefore, it is necessary to release the occupation of the digital signage 100. Therefore, in order to determine the timing of the release, WiGig connection disconnection using the directivity and short-distance characteristics of WiGig is used for determination.
The digital signage 100 utilizes the directivity (beamforming) of WiGig to detect only the user 210 within the front area 250 of the digital signage 100. Also, the digital signage 100 side transmits a signal for recognizing the portable terminal 150, and the portable terminal 150 responds to it, thereby authenticating the portable terminal 150. Therefore, battery consumption on the portable terminal 150 side can also be suppressed.
Further, by using WiGig, two functions of communication for recognizing the portable terminal 150 and data communication to the portable terminal 150 can be used in combination. In addition, because of high-speed communication, large-capacity data communication services are also possible.

FIG. 7 is a flowchart showing an example of processing according to the present embodiment. It is assumed that digital signage 100 permits connections from a plurality of users 210.
In step S702, the content is displayed, operates as WiGig TCP / AP, and transmits a beacon.
The digital signage 100 operates as a WiGig PCP / AP and continues to transmit a beacon while displaying predetermined content.
Here, the WiGig antenna 120 is adjusted to transmit radio waves in front of the digital signage 100. The following is an adjustment method of the WiGig antenna 120.
(1) The person in charge adjusts the orientation of the WiGig antenna 120 so that radio waves are transmitted in an arbitrary direction.
(2) The transmission / reception range of the WiGig antenna 120 is automatically adjusted according to the situation such as the number of people. Although terminal authentication is performed by WiGig connection, the amount of surrounding people is determined from the number of connected terminals, connection frequency, and the like.
If it is determined that there are many people, it is determined that there is a possibility of viewing from multiple directions and distant places, and the range of the WiGig antenna 120 is automatically adjusted. The change of the range of the WiGig antenna 120 may be realized by providing a plurality of WiGig antennas 120 and switching the WiGig antenna 120 to be used.
The recognition process of the portable terminal 150 may be performed not only by the digital signage 100 but also by a small terminal or the like having a WiGig function, for example.

In step S704, the connection from the portable terminal 150 is detected.
When receiving the WiGig radio wave from the digital signage 100, the portable terminal 150 carried by the user 210 operates as a WiGig STA (STAtion), and connects the digital signage 100 with the WiGig. At this time, the portable terminal 150 transmits the portable terminal ID of the portable terminal 150 to the digital signage 100 using the WiGig network.

In step S706, the user is determined, and if the connection is maintained for a predetermined period, the process proceeds to step S708, and if the connection is disconnected, the process returns to step S702.
When the digital signage 100 detects a connection from the portable terminal 150, it performs user determination. There are the following two determination methods. Either may be used.
(1) The digital signage 100 stores the time when the WiGig connection with the portable terminal 150 is established, and when the connection is continued for a predetermined period, the user 210 who is the owner of the portable terminal 150 is the digital signage. It is determined that the advertisement presented at 100 is being viewed. Note that WiGig's radio waves are highly directional and the connectable distance is short, so if you connect with a non-viewer, the connection will be cut off immediately.
(2) Judge as a user when connected by WiGig. This determination method is effective for a service that delivers an advertisement to people who are not browsing or are passing by.

In step S 708, the mobile terminal ID is received, and the mobile terminal information management server 180 is inquired about the mobile terminal ID (or user ID).
The digital signage 100 acquires the portable terminal ID received from the portable terminal 150, queries the portable terminal information management server 180, and acquires user information (specifically, the user information table 600). Here, when the user is already registered in the portable terminal information management server 180, it is determined as "registered user", and when it is not registered, it is determined as "unregistered user". Some services can also be used as an authentication role, such as providing services only to registered users.
If the service does not require user authentication or user identification, this authentication process (the process of step S 708) is unnecessary.
In addition, by performing user authentication, for example, the following service becomes possible.
(1) The data to be displayed on the digital signage 100 and the data to be distributed to the portable terminal 150 are changed according to the user information.
(2) Change the priority of service provision according to user information. For example, when a plurality of users 210 use the service, the registered user may be prioritized.

In step S710, the operation icon is displayed, and an operation accepting state is set.
Digital signage 100 provides a predetermined service to connected user 210 using WiGig communication. For example, there are the following services.
(1) Remote Control Operation The digital signage 100 causes the display device of the digital signage 100 to display an icon dedicated to the portable terminal 150 determined by the user. The portable terminal 150 transmits remote control information to the digital signage 100 using a dedicated application (hereinafter, also referred to as a dedicated application).
The digital signage 100 receives the remote control information from the portable terminal 150, and moves the icon or switches the content in accordance with the operation of the user 210. Specifically, switching of advertisements, map display of shops, etc. are performed.
(2) Distribution of Data The digital signage 100 distributes data such as advertisement information and coupon information (discounted ticket information and coupon information) to the portable terminal 150 determined by the user.

In step S712, it is determined whether or not disconnection has been detected. If the connection is continued, the process proceeds to step S716, and if the connection is disconnected, the process proceeds to step S714.
When ending the use of the digital signage 100 service, the user 210 performs disconnection processing from the dedicated application. When the digital signage 100 receives the disconnection process from the dedicated application, the digital signage 100 determines that the use of the user 210 is ended, and cancels the display of the icon and the like. In addition, the digital signage 100 determines that the use of the user 210 is ended even under the following conditions.
(1) When the WiGig connection from the user 210 is disconnected and a predetermined time has passed (because it can be determined that the user 210 is far away)
(2) When no operation from the user 210 occurs for a predetermined period (3) When a disconnection request from the user 210 is received

In step S714, the operation acceptance is canceled, and the process returns to step S702.
