  Embodiments will be described below with reference to the drawings. In FIG. 1, reference numeral 1000 denotes, for example, a cloud server (hereinafter simply referred to as a server). The server 1000 can communicate with the portable terminal 2000 via the base station 3000.

  The mobile terminal 2000 includes, for example, a personal computer 2001, a tablet 2002, and a mobile phone (smartphone or the like) 2003.

  The server 1000 is connected to the signage terminal 4000 via a network (the Internet, a local area network, a wireless system, a combined system thereof, or the like) 5000. A signage terminal 4000 is shown as a representative, but there are a plurality of signage terminals, and they are installed in places of various environments including outdoor and indoor.

  For example, the installation site of the signage terminal 4000 includes multiple places in the event hall, multiple places in a company, multiple places in a factory, multiple places in a station yard, multiple places in a supermarket or outlet mall, multiple places in a department store, hospitals There are several places of facilities and.

  The signage terminal 4000 includes a transceiver 4001 connected to the Internet, a signal processor 4002 for processing transmission and reception signals, a display 4003, and a control unit 4004 for overall control. In addition, a connection terminal 4005 for connecting a USB memory or the like may be provided.

  FIG. 2 illustrates an example when mutual communication is performed among the portable terminal 2000, the signage terminal 4000, and the server 1000.

  The portable terminal 2000 can acquire an address from the signage terminal 4000 based on an operation by the user (step SA1). This address indicates, for example, a URL (Uniform Resource Locator). There are various methods for acquiring the address, which will be described later.

  The portable terminal 2000 can perform line connection with the server 1000 using the acquired address. When the user wants to upload a message to the signage terminal 4000, the card template is requested to the server 1000 (step SA3). In this case, for example, the user presses the template request button of the card of the portable terminal 2000.

  Then, the server 1000 transmits a card template to the portable terminal 2000 (step SA4). As a result, the portable terminal 2000 creates a content as a card based on the user's operation (step SA5).

  The card will be described later, but it may be called, for example, a frame, a piece for image generation, a template, a strip, a tile, etc., and the name is not limited. The card referred to here includes, for example, the following meaning.

  That is, it can also be captured as an image of a plurality of parts to be attached to the signage screen. There are various parts, and the shape of each card may be basically the same. In the case of the same shape, there is a convenience that it is easy to arrange and arrange on the signage screen.

  In addition, the vertically long common shape may be standard so that the shape of the card is the same as the screen of the smartphone used by the user.

  However, of course, the shape of each card may be different. For example, a shape similar to the smart phone screen of each user, or a shape set or selected by the user may be used. Further, the size, color, shape, etc. of the card may be selected for each type of content to be conveyed by the card, for each user, for each category. For example, the user A and the user B who communicate with each other may be allowed to negotiate the shapes and colors of the cards used with each other. In addition, when telling the destination etc., depending on the transportation to use, the card of the shape of the bus or the card with the mark of the bus, the card of the shape of the train, the card with the mark of the train, the shape of the bicycle A card or a card marked with a bicycle may be made available.

  Each card stores content created by the user, and when the card is posted, a card with content and a designed card are displayed and reproduced on the signage terminal.

  Then, a card with content or a designed card can be obtained as an image from the signage board displayed on the signage terminal on the screen of the portable terminal. The card can be created not only for each user but also for a signage provider.

  As the contents of the card, characters, images, moving pictures, sounds, etc. can be added as categories.

  The card can be grasped as a virtual sense of being stuck, placed, or suspended or floated at a predetermined position in the screen of the signage terminal.

  For example, the method of handling the card can be described in the sense of virtual space in the signage screen. For example, hooks and hangers are provided in advance on the wall, and the user can suspend the card on each of the hooks, and the user gets a sense of taking the card suspended on the hook or the like. be able to.

  In the sense of virtual space, the role of the above-mentioned "wall" is the entire signage screen, and the hanger can be felt as a frame in which each card is arranged.

  Furthermore, in the virtual space, a plurality of cards can be suspended in a pile on one hook. That is, a plurality of cards can be stacked and displayed on each frame. Examples of this usage will be described later.

  The user uses the template on the screen of the portable terminal 2000 to create content for a message. As content, there are a character string, a photo with a comment, and the like.

  The user can write characters in the card template while viewing the screen of the portable terminal 2000 and operating the keyboard on the touch panel. When the portable terminal 2000 has a touch panel input function, characters can also be input by touching a pen tip or a fingertip. Furthermore, when the portable terminal 2000 further has a camera function, it is possible to combine a photo image with a card template.

  The user can finish the card into a favorite card (design) by adding content such as the characters and photos described above.

  Next, when it is desired to upload the card to the server (i.e., the signage terminal), the mobile terminal 2000 is operated to perform the upload (step SA6). The card is sent to the server 1000, and the server 1000 transmits this card to the signage terminal 4000 (step SA7). The card uploaded by the user is thereby displayed on the signage terminal 4000. The card displayed on the signage terminal 4000 can also be deleted by the user who has uploaded the card. The act of “uploading” may be referred to as “action of posting or posting”.

  The card displayed on the signage terminal 4000 can also be downloaded by another user or a user who has uploaded the card. In this case, the number of downloads may be set. In other words, the user performs an operation for uploading the created card to the server 1000. However, before performing this operation, the number of times the card is downloaded is restricted, for example, 10 times, 20 times, 30 times, etc. You may give it. The contents of download are message message (text), voice, picture, etc.

  As described above, the user can feel as if operating the signage terminal 4000 directly with the portable terminal 2000. That is, the portable terminal 2000 and the signage terminal 4000 are in an area physically close to each other. Therefore, when the signage terminal 4000 displays the card (step SA8), the user can feel as if operating the signage terminal that he / she is viewing. In the portable terminal 2000, there is no need to hold a dedicated (or general purpose) application, and the above-described operation (as if the signage terminal 4000 is directly operated) can be performed by accessing the signage terminal 4000. It is.

  FIG. 3 shows that the cards 4011, 4012, 4013 and 4015 are displayed on the signage terminal 4000. In addition, the signage terminal 4000 can display, for example, a QR code (registered trademark) 4020 (hereinafter simply referred to as a code) on the same screen as the screen for displaying a card. This code includes a URL and provides an address for accessing the server 1000.

  The address providing means is not limited to the above method, and there are various methods. The address may be provided by a barcode. Alternatively, AR (Augmented Reality) technology or the like may be applied. For example, when the camera terminal of the mobile terminal 2000 captures, for example, characters of "message board" of the signage terminal 4000, an address for server access may be acquired as augmented reality (AR) data.

  The above code is switched to different contents depending on the time zone. The switching time interval can be arbitrarily set, for example, 30 minutes, 1 hour, 2 hours, 3 hours, 4 hours, and so on. This naturally switches the access address of the server 100 as well.

  The reason why the code is switched as described above is that the code read by the portable terminal 2000 which has read the code is stored, and then the portable terminal 2000 accesses the server 1000 from a place different from the place where the signage terminal 4000 is installed. It is to prevent doing. If the portable terminal 2000 accesses the server 1000 at a place different from the place where the signage terminal 4000 is installed, the user can not view the image (card) of the signage terminal 4000.

  FIG. 4 also shows an example where signage terminal 4000 further includes short range transceiver 4007. The short range transceiver 4007 may communicate with the portable terminal 2000 and provide the portable terminal 2000 with the address of the server 1000.

  The short distance transmitter / receiver 4007 is a weak radio wave, infrared, WiFi (Wireless Fidelity; compliant with IEEE 802.11x), NFC (Near Field communication; low speed magnetic coupling), Blutooth (registered trademark) compliant with IEEE 802.15.1, transfer jet (Transfer Jet; ultra short range high speed wireless communication) may be applied.

  When the signage terminal 4000 can recognize the portable terminal 2000 by the above-described short distance communication, the following usage may be performed. In addition, that the portable terminal 2000 is located in the vicinity of the signage terminal 4000 means that, for example, the signage terminal 4000 recognizes (grasps) the signage terminal 4000 by acquiring GPS (Global Positioning System) information from the portable terminal 2000. It is possible.

  For example, a unique application may be installed in the signage terminal 4000 so that the communication partner can be restricted or controlled. For example, it is also possible for signage terminal 4000 to refuse communication with a specific party. Further, it is also possible to transfer the mobile terminal address of a specific partner to the server 1000. In addition, when the signage terminal 4000 detects a mobile terminal address of a specific partner, it is also possible to notify the specific server of the detection.

  FIG. 5 shows an example where signage terminal 4000 further includes short range transceiver 4007 and camera 4008.

  In the case of this embodiment, a user located near the signage terminal 4000 can be imaged and specified by the camera 4008. The signage terminal 4000 can determine whether the user is located in front of the signage terminal 4000 and looks into the screen of the signage terminal 4000.

  When the user is located near the signage terminal 4000 and in a specific area (imaging area), the signage terminal 4000 can determine that the user intends to use the signage system. At this time, signage terminal 4000 may provide operation guidance to the user through voice or image.

  Also in this embodiment, the signage terminal 4000 can recognize the user and the portable terminal 2000. For this purpose, for example, it is also possible to refuse the user to use signage. It is also possible to transfer the user's face image to the server 1000 or a specific server. It is also possible to compare the user's face image with the past user's face image and to identify an inappropriate user.

  FIG. 6A is a diagram showing a display example of signage terminal 4000 and an operation example of portable terminal 2000 (2003). The portable terminal 2003 has a display that doubles as a touch panel. When the portable terminal 2003 receives an address from the signage terminal 4000 and joins the signage system, the portable terminal 2003 shifts to the operation mode of the signage terminal 4000.

  The portable terminal 2003 can select (designate) one of the cards 4011 to 4015 displayed on the signage terminal 4000.

  For example, an arrow-like selection mark 2012 is displayed on the display of the portable terminal 2003. When the user swipes the selection mark 2012 in the direction (right direction) indicated by the arrow, the designation mark displayed on the signage terminal 4000 is the position of the designation mark 4031 from the position of the designation mark 4031 (position of the card 4011). It can be moved to (the position of the card 4012). Further, when the user swipes the selection mark 2012 in the arrow direction (right direction), the designation mark can be moved to the position of the next card 4013. In addition, when the selection mark 2012 is swiped in the direction (left direction) indicated by the arrow, the designation mark moves to the left by one card every operation (swipe). Thus, the user can designate a desired card.

  The portable terminal 2003 can display the download mark 2014 on the display. For example, in a state in which the card 4011 is designated, when the download mark 2014 is swipe in the arrow direction, the portable terminal 2003 can acquire the card 4011. The card 4011 is actually sent from the server 1000 to the portable terminal 2003.

  The portable terminal 2003 can display the posting mark 2011 on the display. When the posting mark 2011 is swiped in the direction of the arrow, the created card can be displayed on the signage terminal 4000. In practice, the card created from the portable terminal 2003 to the server 1000 is transmitted.

  The portable terminal 2003 can display the deletion mark 2013 on the display. The user operates the selection mark 2012 and can specify a card to be deleted by the designation mark. Then, when the deletion mark 2013 is swipe or touched while the card to be deleted is designated by the designation mark, the designated card is deleted. However, the card that can be deleted is usually only the card submitted from the portable terminal 2003 that created the card. In addition, the person who can delete the card is only a specific person (manager of digital signage). A manager can, for example, possess a special authorization number to operate digital signage.

  Note that, as shown in FIG. 6B, the selection mark and the download mark on the portable terminal 2003 (2000) indicate, for example, arrow marks in a direction from the background screen display 2050 capable of recognizing the message board to the portable terminal 2003 (2000). Marks) 2052 may be arranged (and display examples) such as a rightward arrow mark 2053 and a leftward arrow mark 2054 which indicate movement from one column (item column) of the message board to the next column. Further, in the display example (arrangement) shown in FIG. 6B, the arrow mark in the direction toward the message board (signage terminal) 4000 in the next screen (FIG. 6C) which is switched by turning on the POST MESSAGE button 2051 May be displayed.

  In FIG. 7, it is assumed that the content of the card 4013 is a card 4013 saying "Career and ticket for today's baseball game" and "Please download this message and come to wear ...". In the case of such a card 4013, it is expected that many people want a ticket. Therefore, the ticket provider (the user who uploaded the card) can limit the number of downloads. In the example of FIG. 7, it is shown that the cards are superimposed in an instant manner (visually visible) that the number of times the card has been downloaded is four. In the example of FIG. 7, the number of remaining cards is displayed one by one each time it is downloaded.

  Although the above example limits the number of downloads, the download period and time may be limited. For example, if the sale advertisement for a product is performed through a card, the period or time of the advertisement may be set. When a period or time is set, the card is automatically erased when the set period or time has elapsed.

  FIG. 8A shows an example in which there are a large number of postings to the signage terminal 4000, and the card is displayed in a reduced size. In the digital signage system of the embodiment, for example, 100 postings are possible for one signage terminal. In the display example shown in FIG. 8A, it is possible to distinguish that a plurality of users are accessing a plurality of cards at the same time (or a plurality of users are accessing one card). An identifier (identification display) 4016a (card 4016), 4017a (card 4017), 4018a, 4018b (card 4018) which can be viewed by the user is displayed at a predetermined position in the vicinity of the card. The identifier (identification display) is, for example, a color bar (marking by color) or coloring of the outer frame of the card (changes the color of the entire circumference or a part of the outer frame of the card), or the MAC address (Media Access Control) In accordance with the above, it is possible to use a model display according to the above, or a display of a number of digits (in a portable terminal) of a telephone number, and a combination thereof. Of course, the access number may be a serial number from 1 (serial number), in which case the serial number corresponding to the access order is transmitted from signage terminal 4000 to each mobile terminal (user). Preferably, the same serial number is maintained until communication with the portable terminal (user) ends.

  FIG. 8B shows an example in which the card 4017 selected by the user is enlarged and displayed among a large number of cards displayed on the signage terminal 4000.

  The embodiment showing the change of the display state in FIG. 8A to FIG. 8B is an example when the card enlargement display function is operated. When many cards are reduced and displayed on the signage terminal 4000, the user may find it difficult to view the contents of the cards. Then, if a desired card is selected as shown in FIG. 8A and, for example, the enlargement button 2015 of the portable terminal 4000 is touched, the desired card 4017 is enlarged and displayed as shown in FIG. 8B. In the display example of FIG. 8A, when moving the selection mark 2012 in the direction indicated by the arrow next to the card on the right of the card positioned on the first row (upper row), the left end of the second row (lower row) In the example of jumping to a card, it is also possible to move to the card at the right end of the second line (below, and then move one card at a time toward the left card.

  FIG. 9 shows an example of a system operation in the case where signage terminal 4000 has a function of recognizing the user of portable terminal 2000. The signage terminal 2000 can acquire the portable terminal number of the portable terminal 2000 or the face image of the user (step SB1). Signage terminal 2000 transmits the acquired user information, for example, a face image to server 1000 (step SB2).

  Then, the server 1000 can identify the user using the face image of the user and the database, and determine whether the user is a qualified person or a disqualified person (step SB3). The ineligible person may be, for example, a criminal, or a history of destroying a signage terminal in the past. In such a case, the server 1000 can transmit a warning screen, a warning sentence, a warning sound or the like to the signage terminal 4000 (step SB4).

  FIG. 10 shows an example of system operation when the server 1000 has a function of recognizing the user of the portable terminal 2000. The portable terminal 2000 acquires an address from the signage terminal 4000 (step SC1). Then, the signage terminal 4000 performs line connection with the server 1000 using the acquired address (SC2). At this time, the server 1000 determines whether the user is a person suitable for using signage based on the mobile number of the mobile terminal 2000 (ID (identification information) unique to the user) ( Step SC3). If the user is an ineligible person, notification is made that the user's portable terminal 2000 is ineligible (SC4).

  For example, if the card is a card that can be used by special members, the above-described determination of the eligible and non-qualified persons may be made.

  FIG. 11 shows that when requesting a card template from the portable terminal 2000 to the server 1000, it is possible to select a template to be used from various types of templates. FIG. 11 shows various types of templates 2031, 2032 and 2033 having different designs and colors.

  FIG. 12 shows an example in which a signage terminal 4000 is used at, for example, a reception of a hospital. The signage terminal 4000 is used to register the examination order of patients who have visited the hospital. At this time, the user can receive a card for medical examination order registration from the server. When the card is filled with a nomination and uploaded, the nomination is displayed on the signage terminal 4000 for medical examination reception, and registration of the examination order is completed.

  When the user's mobile terminal 2000 is downloaded, the signage terminal 4000 can determine that the user has canceled the medical examination or entered the medical examination room. Then, it is possible to notify that the medical examination is approaching from the user who has entered the current cancellation or examination room to the portable terminals of other users who have made a reservation, for example, about 5 persons later.

  FIG. 13A shows that, for example, Tom operates a portable terminal (smart phone) 2000 to post a card describing a message on a signage terminal 4000.

  FIG. 13B shows that Betty, for example, downloads a message posted by Tom while operating the mobile terminal (smart phone) 2000 and looking at the signage terminal 4000.

  In FIG. 14, Tom takes a picture of a person or a picture of a catalog using the camera function of the portable terminal 2000, attaches the picture to a card, creates a card for posting, and signs this card. The state of posting on the terminal 4000 is shown. In this case, a message may be added to the card together with the picture. The message may be implemented by, for example, handwriting input or pen input, or may be input from a keyboard.

  FIG. 15 shows, for example, a plurality of clothing stores (one store may post a plurality of cards) using a smartphone to post clothing advertisements. The store clerk at the clothing store takes a picture of a model or mannequin with, using the camera function of the mobile terminal (eg smart phone). Next, the user operates the mobile terminal and pastes the taken picture on the card to be used. Then, it is possible to come to the peripheral area of the signage terminal near the store and post a card having the taken image as the content. In this case, voice data can also be posted along with the card. When the user downloads the card, the downloaded smart phone can also receive an audio explanation.

  FIG. 16 is an example of a typical installation location showing where the signage terminal according to the present embodiment is installed. For example, signage 4000 (1) may be installed on the side of the building road. Also, for example, a large signage 4000 (2) may be installed on the wall of a building. For example, signs 4000 (3) and 4000 (4) may be installed at the entrance of a building or in information. Also, 4000 (5) may be installed in the building.

  FIG. 17 is an example showing where the mobile terminal of the user for using the signage terminal according to the present embodiment actually performs electrical communication.

  The portable terminal 2000 actually communicates with the web socket server and the web server. At this time, the signage terminal 4000 installed near the portable terminal 2000 is controlled by the server and can behave as if it were communicating with the portable terminal 2000.
