Description

The present invention relates to a technique for displaying information to passersby.

In recent years, IC cards have been widely used as tickets for the use of transportation. The IC card used as a ticket stores information such as the name of the holder, and causes a ticket vending machine, an automatic ticket gate, or the like to read the stored information. Therefore, a technique has been proposed in which personal information such as the language used by the holder is stored in the IC card, and guidance corresponding to the personal information read from the IC card is displayed at a ticket vending machine, an automatic ticket gate, or the like. ..

For example, in Patent Document 1, when a passerby passes through an automatic ticket gate, advertising information corresponding to the passerby's personal information read from an IC card used by the automatic ticket gate as a ticket is displayed to the passerby. The mechanism to do this is described. Further, in Patent Document 2, when a passerby passes through an automatic ticket gate, guidance information is displayed to the passerby in the language used by the passerby read from the IC card used by the automatic ticket gate as a ticket. The mechanism is described.

It is widely practiced to display various information such as destination information and area information to an unspecified number of passers-by by using an electric bulletin board installed in a public place such as a station yard. In Japan, many passers-by can understand Japanese, but some passers-by cannot. Therefore, a mechanism for simultaneously displaying the same information in both Japanese and a foreign language on a display device such as an electric bulletin board, and a mechanism for displaying the same information alternately in Japanese and a foreign language are becoming widespread.

At present, English, Chinese, and Korean are often selected as foreign languages used when displaying information on electric bulletin boards. This is because many foreigners visiting Japan use these languages. However, some foreigners do not understand Japanese, English, Chinese, or Korean. There is a problem that public guidance cannot be provided to such foreigners by the conventional system.

In addition, the size of characters displayed on the electric bulletin board and the displayed time are not always appropriate for all passers-by. For example, for elderly passers-by, the characters displayed on the electric bulletin board may be too small to be read, or the displayed time may be too short to read the guide to the end. In addition, for children in the lower grades, information may be displayed on the electric bulletin board in kanji or wording that they do not yet remember, and the guidance may not be understood.

Hereinafter, the information display system 1 according to the embodiment of the present invention will be described. The information display system 1 is a system that provides destination guidance by displaying characters and voice to an unspecified passerby who passes through the ticket gate of a station.

FIG. 1 is a diagram showing an overall configuration of the information display system 1. The information display system 1 has an automatic ticket gate 11 that manages entry to the area P in the ticket gate, an automatic ticket gate 12 that manages entry from the area P, and a place that can be seen by an unspecified passerby in the area P. It includes the installed guide devices 13-1 and 13-2, a camera 14 installed so as to take a picture from the inside of the area P toward the automatic ticket gate 11, and a server device 15. The guide devices 13-1 and 13-2 are devices having the same configuration. Hereinafter, when the guide devices 13-1 and 13-2 are not distinguished, they are collectively referred to as "guidance device 13". Note that FIG. 1 shows train T as an example of transportation.

The automatic ticket gate 11 and the automatic ticket gate 12 are based on information read from an IC card C (an example of a passerby's personal belongings) carried by a passerby as a ticket (an example of an admission ticket), for example, by opening and closing a gate. It is a device that allows or prohibits passersby from entering and exiting the area P. The automatic ticket gate 11 and the automatic ticket gate 12 are provided with a communication interface and communicate with the server device 15. Since the automatic ticket gate 11 and the automatic ticket gate 12 are known devices, detailed description thereof will be omitted.

In the present embodiment, the IC card C is a ticket for the balance of charged electronic money, records of entry / exit to / from the station ticket gate used in the past (entrance station name, entry time, exit station name, exit time, etc.) In addition to the information related to the function of, the attribute information indicating the attribute of the passerby carrying the IC card C is held. In the present embodiment, the attribute information held by the IC card C includes the language used by the passerby (one or two), the age, and the presence or absence of visual impairment.

The guidance device 13 is a device that guides passers-by in the area P by displaying characters and pronouncing voice in accordance with instructions from the server device 15. The guide device 13 also plays a role of photographing a passerby in front of the guide device 13. FIG. 2 is a diagram showing the appearance of the guide device 13. The guidance device 13 includes a display 131 (an example of a display device), a speaker 132, and a camera 133. Further, the guidance device 13 includes a communication interface (not shown) for communicating with the server device 15.

As illustrated in FIG. 2, the display 131 can simultaneously display the same destination guidance in two different languages. The speaker 132 produces a voice represented by the voice information transmitted from the server device 15. The camera 133 continuously photographs a passerby in front of the guidance device 13. The guidance device 13 sequentially transmits image information representing an image taken by the camera 133 to the server device 15.

The camera 14 continuously photographs passers-by who pass through the automatic ticket gate 11 and enter the area P. The camera 14 includes a communication interface, and sequentially transmits image information representing the captured image to the server device 15.

The server device 15 is a computer including a processor, a memory, and a communication interface. The server device 15 sequentially receives from the host system (not shown) a guide table, which is a collection of destination guide information indicating the contents of the destination guide that changes every moment according to the train operation status, and uses the received guide table as the guide table. It plays a role of instructing the guidance device 13 on the destination guidance indicated by the included destination guidance information.

FIG. 3 is a diagram showing the configuration of the guide table. A guide table is a collection of records corresponding to each of a plurality of destination guide information. A plurality of destination guidance information included in one guidance table indicates text expressing the same content in different languages or in an expression form according to the age group of passersby.

The information table has fields "language", "age group", and "text". Language information such as "Japanese" and "English" is stored in the field "Language". In the field "age group", age group information indicating either "young age group" or "middle-aged age group" is stored. For example, "younger age group" means 10 years old or younger, and "middle and older age group" means 11 years old or older. In the field "text", text information (that is, destination guidance information) indicating the content of the destination guidance is stored.

In one guide table, a plurality of destination guide information included in the guide table is identified by a combination of language and age group. Hereinafter, the combination of language and age group is referred to as "language attribute" for convenience.

For example, if the destination guidance information according to the language attribute "Japanese / Middle-aged and older" is "Express / Fujisawa / 11: 59 / Sagamiono will contact the limited express bound for Odawara.", It will be stored in the same guidance table. The destination guidance information according to the language attribute "English / middle-aged" is, for example, "Express / Fujisawa / 11: 59 / It connects to a limited express to Odawara in Sagamiono.", And the language attribute is "Japanese / For destination information according to the "younger age group", for example, "(Fujisawa) Ikino (Kyukou) will be available at 11:59. (Sagamiono) and (Odawara) Ikino (Tokkyu). You can change to another. "

The server device 15 sets the destination according to two (a predetermined number of examples) language attributes from the plurality of destination guidance information stored in the latest guidance table every time a predetermined time (for example, 15 seconds) elapses. Guidance information is selected, and a display instruction including the destination guidance information is transmitted to the guidance device 13.

The guidance device 13 displays the text indicated by the destination guidance information included in the display instruction transmitted from the server device 15. That is, the guidance device 13 repeats the operation of displaying the destination guidance having the same contents at the same time in two expression forms for a predetermined time and then displaying the destination guidance in two different expression forms for a predetermined time.

The server device 15 provides the destination guidance information according to the language attribute of a visually impaired passerby in the area P indicated by the attribute information read from the passerby's IC card C by the automatic ticket gate 11. Select as destination guidance information to be included in the display instructions to be sent to. Therefore, the guidance device 13 displays the destination guidance in an appropriate expression form according to the language attribute of a passerby who is not visually impaired in the area P.

Further, the server device 15 selects destination guidance information according to one (a predetermined number of examples) language attributes from a plurality of destination guidance information stored in the latest guidance table, and the destination guidance information is used. The voice that reads out the indicated content is synthesized, and a pronunciation instruction including voice information representing the synthesized voice is transmitted to the guidance device 13. After transmitting the pronunciation instruction to the guidance device 13, the server device 15 selects new destination guidance information from the guidance table when the reproduction time of the voice represented by the voice information included in the pronunciation instruction elapses, and the destination guidance information. A pronunciation instruction including voice information corresponding to the above is transmitted to the guidance device 13.

The guidance device 13 produces a voice represented by voice information included in the sounding instruction transmitted from the server device 15. That is, the guidance device 13 repeats the operation of pronouncing the destination guidance having the same content in a certain expression form and then pronouncing it in another expression form.

The server device 15 provides the guidance device 13 with destination guidance information according to the language attribute of a visually impaired passerby in the area P, which is indicated by the attribute information read from the IC card C of the passerby by the automatic ticket gate 11. It is selected as the destination guidance information used for synthesizing the voice information to be included in the pronunciation instruction to be transmitted. Therefore, the guidance device 13 pronounces the destination guidance in an appropriate expression form according to the language attribute of the visually impaired passerby in the area P.

FIG. 4 is a diagram showing a functional configuration of the server device 15. When the processor included in the server device 15 performs information processing according to the program stored in the memory, the server device 15 operates as a device including the functional component shown in FIG. The functional components of the server device 15 shown in FIG. 4 will be described below.

The information stored in the storage unit 152 includes various tables (described later) used in the process of selecting destination guidance information. The information update unit 153 updates a part of those tables stored in the storage unit 152.

The image recognition unit 154 recognizes a passerby from the image information transmitted from the camera 14 and the camera 133. Since the image recognition process performed by the image recognition unit 154 is known, the description thereof will be omitted.

The selection unit 155 selects the destination guidance information used for the display instruction and the pronunciation instruction to be transmitted to the guidance device 13 from the plurality of destination guidance information included in the guidance table (FIG. 3).

The voice synthesis unit 156 synthesizes the voice read out from the text indicated by the destination guidance information selected by the selection unit 155. Since the speech synthesis process performed by the speech synthesis unit 156 is known, the description thereof will be omitted.

The collation unit 157 includes the characteristics of the passerby recognized by the image recognition unit 154 from the image information transmitted from the camera 14 and the characteristics of the passerby recognized by the image recognition unit 154 from the image information transmitted from the camera 133. To match.

Next, various tables used by the server device 15 for processing the selection of destination guidance information will be described. The storage unit 152 stores a hall passerby table, a device front passerby table, a notification order table, and a notification history table as tables used for processing the selection of destination guidance information.

The passerby table in the hall is a table that stores attribute information of passersby for which a predetermined time (for example, 15 minutes) has not passed after passing through the automatic ticket gate 11. The passerby whose attribute information is stored in the passerby table in the hall is a passerby who is presumed not to have boarded the train after entering the area P.

FIG. 5 is a diagram showing the configuration of a passerby table in the hall. The passerby table is a collection of records for each passerby. The passerby table in the hall has fields "passer ID", "entrance time", "language used 1", "language used 2", "age", "presence or absence of visual impairment", and "characteristics".

In the field "passer ID", identification information for identifying a passerby in the passerby table in the hall is stored. In the field "entrance time", time information indicating the time when a passerby has passed the automatic ticket gate 11 is stored. In the fields "Language 1", "Language 2", "Age", and "Presence / absence of visual impairment", the attribute information according to the field names read by the automatic ticket gate 11 from the passerby's IC card C is displayed. It is stored.

In the field "feature", feature information indicating the characteristics of the passerby recognized by the image recognition unit 154 from the image taken by the camera 14 at the timing when the passerby passes through the automatic ticket gate 11 is stored.

The record of the passerby table in the hall is deleted by the information update unit 153 when a predetermined time (for example, 15 minutes) has elapsed from the time of admission.

The passerby table in front of the device is a table that stores the passerby ID of the passerby recognized by the image recognition unit 154 from the image taken by the camera 133 of the guidance device 13 within the latest predetermined time (for example, 1 minute). Therefore, the storage unit 152 stores the device front passerby table corresponding to each of the guide device 13-1 and the guide device 13-2. The passerby whose passerby ID is stored in the passerby table in front of the device is a passerby who is presumed to be currently in front of the guidance device 13.

FIG. 6 is a diagram showing the configuration of a passerby table in front of the device. The device front passerby table has fields "recognition time", "features", and "passerby ID". In the field "recognition time", time information indicating the time when the image recognition unit 154 recognizes a passerby is stored. In the field "feature", feature information indicating the features of the passerby recognized by the image recognition unit 154 is stored.

When the feature information is stored in the field "feature", the collation unit 157 collates the feature information with the feature information stored in the passerby table (FIG. 3). In the field "passer ID" of the passerby table in front of the device, when the matching feature information is found from the passerby table in the hall by the collation unit 157, the passerby ID corresponding to the feature information is stored.

The record in the passerby table in front of the device is deleted by the information update unit 153 when a predetermined time (for example, 1 minute) has elapsed from the recognition time.

The notification order table is a table that stores the language attributes of the destination guidance notified (displayed or pronounced) by the guidance device 13 selected by the selection unit 155 in the order of notification. The storage unit 152 stores a notification sequence table for displaying the destination guide and a notification sequence table for sounding the destination guide for each of the guide device 13-1 and the guide device 13-2.

FIG. 7 is a diagram showing the configuration of the notification order table. The notification sequence table has fields "order", "language", "age group", and "elderly flag". The field "order" stores order information indicating the order of notifications. In the fields "language" and "age group", language information and age group information for identifying the expression form of the destination guide are stored.

In the field "elderly flag", there is an elderly flag indicating whether or not the passersby of the language attribute indicated by the language information and the age group information stored in the same record include the elderly (for example, 65 years or older). It is stored. If the senior citizen flag is set (value is True), it means that senior citizens are included. Notification of display When the elderly flag of a record included in the order table is set, the destination guidance of the expression form according to the language attribute of the record is displayed for a longer time than usual (for example, twice the normal time). Will be done. In addition, when the elderly flag of the record included in the notification order table regarding pronunciation is set, the destination guidance of the expression form according to the language attribute of the record is slower than usual (for example, 1.5 times the normal). It is pronounced (over time).

In the notification order table for display, the records having the order "1" and "2" are the records corresponding to the language attribute of the destination guidance currently displayed by the guidance device 13, and the order is "3" or later. Is a record corresponding to the language attribute of the destination guide to be displayed by the guide device 13 in the future.

Further, in the notification order table for pronunciation, the record having the order "1" is the record corresponding to the language attribute of the destination guidance currently pronounced by the guidance device 13, and the record having the order "2" or later. Is a record corresponding to the language attribute of the destination guide to be pronounced by the guide device 13 in the future.

When the notification (display or pronunciation) of the destination guidance in the expression form corresponding to a certain language attribute is completed, the record corresponding to the language attribute is deleted from the notification order table by the information update unit 153.

The notification history table is a table that stores the language attributes according to the expression form of the destination guide that has been notified (displayed or pronounced) most recently, in the order of notification. In the storage unit 152, for each of the guidance device 13-1 and the guidance device 13-2, a notification sequence table for storing the language attributes corresponding to the recently displayed destination guidance and the language attributes corresponding to the recently pronounced destination guidance are stored in the storage unit 152. The notification sequence table to be stored is stored.

FIG. 8 is a diagram showing the configuration of the notification history table. There is an upper limit (for example, 4) to the number of records included in the notification history table, and when a new record is added, the number of records exceeding the upper limit is deleted in order from the oldest one.

The notification history table has fields "order", "language", and "age group". The field "order" stores order information indicating the notified order. In the fields "language" and "age group", language information and age group information for identifying the expression form of the destination guide are stored. For example, the record having the order "1" stores the language attribute according to the expression form of the notification made immediately before the notification (display or pronunciation) of the destination guidance currently being performed.

When the notification (display or pronunciation) of the destination guidance in the expression form corresponding to a certain language attribute is completed, the notification history table is displayed with a predetermined number (for example, four) of the destination guidance most recently notified by the information update unit 153. It is updated to store the language attribute according to the expression form of.

The above is the description of the various tables used by the server device 15 for the process of selecting the destination guidance information.

The destination guidance information included in the display instruction transmitted from the server device 15 to the guidance device 13 is a record in which the order of the notification order table (FIG. 7) regarding the display at the time of transmitting the display instruction is "1" and "2". This is information stored in the field "text" of the record of the guide table (FIG. 3) according to the language attribute.

Further, the voice information included in the pronunciation instruction transmitted from the server device 15 to the guidance device 13 is set to the language attribute of the record in which the order of the notification order table (FIG. 7) regarding the pronunciation at the time of transmitting the pronunciation instruction is "1". This is information representing the voice of reading the text stored in the field "text" of the record of the guide table (FIG. 3).

As described above, the notification order table is updated by the information update unit 153 when the notification is completed. That is, the record for the completed notification is deleted from the notification sequence table. In addition to the update of the notification sequence table performed by the information update unit 153 when the notification is completed, the selection unit 155 of the server device 15 sets the table of passersby in the hall at that time every predetermined time (for example, 1 minute). The notification order table is updated based on the information stored in FIG. 5). The update procedure will be described below.

Every time a predetermined time (for example, 1 minute) elapses, the selection unit 155 extracts a record in which "None" is stored in the field "Presence / absence of visual impairment" from the passerby table in the hall, and is a collection of the extracted records. Create a table for a certain work (hereinafter referred to as "workplace passerby table").

Subsequently, the selection unit 155 generates an empty work table (hereinafter, referred to as “work notification order table”) having the same fields as the notification order table (FIG. 7).

Subsequently, the selection unit 155 performs a process according to the flow shown in FIG. First, the number of records in the work place passerby table is counted for each language attribute (combination of language and age group) stored in those records (step S101).

The work hall passerby table has fields "language 1" and "language used 2", similarly to the hall passerby table (FIG. 5). For a record in which language information is stored in each of these two fields, the selection unit 155 counts the record as a record corresponding to the language attribute corresponding to each of the two languages used.

For example, if the passerby table in the work place contains a record in which the language 1 is "Japanese", the language 2 is "English", and the age is "23 years old", the selection unit 155 relates to this record. , It is counted as a record of the language attribute "Japanese / middle-aged group" and also as a record of the language attribute "English / middle-aged group".

Subsequently, the selection unit 155 adds a record storing the language attribute having the largest number counted in step S101 to the work notification sequence table (step S102). For example, in step S101, if the number counted for the record of the language attribute "Japanese / middle and old age group" is the largest, the selection unit 155 adds a new record to the work notification order table and sets the field "order". A numerical value obtained by adding 1 to the maximum value of an existing record is stored, "Japanese" is stored in the field "language", and "middle-aged age group" is stored in the field "age group".

Subsequently, the selection unit 155 may store the age information indicating the age corresponding to the elderly (for example, 65 years or older) in the record of the most language attributes included in the passerby table in the workplace. Whether or not it is determined (step S103). When it is determined that the record of the most language attributes included in the passerby table in the work place stores the age information indicating the age corresponding to the elderly (step S103; Yes), the selection unit 155 “True” is stored in the field “elderly flag” of the record added to the work notification sequence table in step S102 (step S104).

When it is determined that none of the records with the most language attributes included in the worksite passerby table stores age information indicating the age corresponding to the elderly (for example, 65 years or older) (step S103). ; No) or when the process of step S104 is completed, the selection unit 155 deletes the record having the largest number of language attributes from the passerby table in the work place (step S105).

For example, when the most language attribute of the record included in the work place passerby table is "Japanese / middle and old age group", the selection unit 155 changes the field "language used" from the work place passerby table in step S105. Delete all the records in which "Japanese" is stored in "1" or "Language used 2" and the age information indicating the age of 11 years or older is stored in the field "Age".

Subsequently, the selection unit 155 determines whether or not one or more records are included in the work place passerby table (step S106). When one or more records are included in the work place passerby table (step S106; Yes), the selection unit 155 uses the work place passerby table after deleting some records in step S105 in step S101. The subsequent processing is repeated.

When no record is included in the passerby table in the work place (step S106; No), the selection unit 155 uses the work notification sequence table to guide device 13-1 and guide device 13-2, respectively. The process for updating the notification order table for display (the following steps S107 to S109) is performed.

First, the selection unit 155 puts a record indicating those language attributes at the end of the notification sequence table, if there is a language attribute that is indicated by any record of the work notification sequence table and does not indicate any record of the notification sequence table. Add (step S107). The order of the records added to the notification order table follows the order of the corresponding records in the work place passerby table.

Subsequently, the selection unit 155 indicates a language indicated by any record in the notification sequence table (excluding the record corresponding to the language attribute currently being notified) and does not indicate any record in the work notification sequence table. If there are attributes, the records indicating those language attributes are deleted from the notification sequence table (step S108).

Subsequently, the selection unit 155 stores the information stored in the field "elderly flag" of the record of the notification sequence table in the field "elderly flag" of the record indicating the same language attribute of the work notification sequence table. Update with the information (step S109).

By the process according to the flow of FIG. 9, the notification order table is updated according to the attributes of the passersby who are currently estimated to be in the area P.

The above-mentioned process is a process of updating the notification order table related to display. The selection unit 155 also performs the same processing on the notification order table regarding pronunciation. That is, in parallel with the above-described processing, the selection unit 155 stores a record in which "Yes" is stored in the field "Presence / absence of visual impairment" from the passerby table in the hall every time a predetermined time (for example, 1 minute) elapses. Is extracted to generate a work table (passerby table in the work place) which is a collection of the extracted records.

Subsequently, the selection unit 155 generates an empty work table (work notification order table) having the same fields as the notification order table (FIG. 7).

Subsequently, the selection unit 155 performs a process according to the flow shown in FIG. 9 by using the work place passer-by table and the work notification sequence table generated as described above. As a result, the notification sequence table for pronunciation is also updated according to the attributes of the passersby who are currently presumed to be in the area P.

In the present embodiment, the selection unit 155 stores the order of the records included in the notification order table updated every time a predetermined time (for example, 1 minute) elapses as described above in the device front passerby table (FIG. 6). Adjust based on the information provided. This adjustment process is a process of increasing the order of notification of the expression form according to the language attribute of the passerby in front of the guidance device 13. Therefore, this adjustment process is performed for each of the guide device 13-1 and the guide device 13-2. The adjustment procedure will be described below.

Every time a predetermined time (for example, 15 seconds) elapses, the selection unit 155 extracts and extracts a record in which "None" is stored in the field "Presence / absence of visual impairment" from the passerby table (FIG. 5). Generate a work table (passerby table in the work place) that is a collection of records.

Subsequently, the selection unit 155 leaves a record for storing the passerby ID stored in any record of the passerby table in front of the device among the records of the passerby table in the work place, and deletes the other records. ..

Subsequently, the selection unit 155 generates an empty work table (work notification order table) having the same fields as the notification order table (FIG. 7).

Subsequently, the selection unit 155 performs a process according to the flow shown in FIG. 10 by using the work place passer-by table and the work notification sequence table generated as described above.

Steps S201 to S206 of FIG. 10 are the same processes as steps S101 to S106 of FIG. 9 except that the records included in the work place passerby table are different. Therefore, the description of steps S201 to S206 will be omitted.

Subsequently, the selection unit 155 deletes a record storing the same language attribute as any record in the notification history table (FIG. 8) from the work notification sequence table (step S207). This process is a process for avoiding the inconvenience that the notifications of the same expression form are repeated when the order of the notifications of the expression form performed most recently is raised.

Subsequently, the selection unit 155 searches the notification sequence table for records that store the same language attributes as the records in the work notification sequence table (excluding records corresponding to the language attributes currently being notified). Then, the order of the searched records is changed so that the order follows the records according to the language attribute currently being notified (step S208).

In the notification order table related to display, the records of the order "1" and "2" are the records corresponding to the language attribute to which the notification is currently performed. Therefore, when the selection unit 155 searches, for example, three records from the notification order table in step S208, the order of the three records is changed to "3", "4", and "5", and the order of the other records is changed. Move the order down as appropriate.

By the process according to the flow of FIG. 10, the order of the records in the notification order table is adjusted according to the attribute of the passerby who is presumed to be in front of the guidance device 13.

The above-mentioned process is a process of adjusting the notification order table related to display. The selection unit 155 also performs the same processing on the notification order table related to pronunciation. That is, in parallel with the above-described processing, the selection unit 155 stores a record in which "Yes" is stored in the field "Presence / absence of visual impairment" from the passerby table in the hall every time a predetermined time (for example, 15 seconds) elapses. Is extracted to generate a work table (passerby table in the work place) which is a collection of the extracted records.

Subsequently, the selection unit 155 leaves a record for storing the passerby ID stored in any record of the passerby table in front of the device among the records of the passerby table in the work place, and deletes the other records. ..

Subsequently, the selection unit 155 generates an empty work table (work notification order table) having the same fields as the notification order table (FIG. 7).

Subsequently, the selection unit 155 performs a process according to the flow shown in FIG. 10 by using the work place passer-by table and the work notification sequence table generated as described above. As a result, the notification sequence table for pronunciation is also updated according to the attributes of the passersby who are currently presumed to be in front of the guidance device 13.

According to the information display system 1 described above, the destination guidance is notified (displayed or pronounced) in a manner corresponding to the attributes of the passersby in the area P. Further, according to the information display system 1, notification (display or pronunciation) of destination guidance is given priority in a manner corresponding to the attributes of passersby in front of the guidance device 13. Therefore, even passers-by with a minority attribute (for example, passers-by who can understand only a minor language) are provided with an understood destination guide.

[Modification example]
The above embodiments can be modified in various ways. An example of these modifications is shown below. In addition, two or more modified examples shown below may be combined as appropriate.

(1) The information notified by the guidance device 13 to passersby is not limited to destination guidance. For example, when a passerby passes through the automatic ticket gate 11, a magnetic ticket is used instead of the IC card C, and the station name of the destination is used for the magnetic ticket (an example of information indicating a section in which a visitor moves by transportation). Is recorded, the guidance device 13 displays information (shop guide, event guide, etc.) according to the section from the station where the guidance device 13 is installed to the destination station on the display 131. It may be configured.

You may. In that case, any one of the automatic ticket gate 11, the guidance device 13, and the server device 15 may receive the attribute information from the terminal device, or a device other than any of these devices receives the attribute information from the terminal device. The received attribute information may be transmitted to the server device 15.

(3) Instead of or in addition to acquiring the passerby attribute information from the IC card C, the information display system 1 obtains the passerby attribute from the image taken by the camera (for example, camera 14 or camera 133). May be configured to identify. For example, it may be configured to specify the age group of the passerby from the facial features of the passerby recognized by the image recognition unit 154. Further, if the passerby attaches a key chain with a mark such as a national flag corresponding to his / her language to a visible position, the image recognition unit 154 recognizes the mark and identifies the language used by the passerby. It may be configured as follows. Further, when it is found from the image recognized by the image recognition unit 154 that the passerby is using the white cane, it may be configured to determine that the passerby has a visual impairment.

(4) The mode of notification that the guidance device 13 changes according to the attribute information of the passerby is not limited to that illustrated in the embodiment. For example, in the above-described embodiment, when the passersby include an elderly person, the guidance device 13 lengthens the display time of the destination guidance longer than usual. Alternatively or additionally, if the passers-by include the elderly, the destination guidance may be displayed in larger letters than usual.

(5) The space in which the guide device 13 notifies passersby is not limited to the space where entry and exit are restricted, such as area P in the ticket gate. The information display system 1 may be used to notify the passerby of information on a road or the like where the passerby can freely come and go.

(6) Specific numerical values (for example, the size of a predetermined time, the number of guide devices 13, etc.), the processing order, the table configuration, etc. used in the above-described description of the embodiment are examples and may be changed in various ways. May be done.

(7) If there is no one in the area P, the notification order table is empty. In that case, the guidance device 13 may be configured not to give any notification, or the guidance device 13 may give a notification in a manner corresponding to a predetermined language attribute such as "Japanese / middle-aged person". It may be configured.

(8) The information display system 1 identifies the position of each passerby, and among the plurality of guide devices 13 arranged at different positions, the guide device 13 according to each passerby (for example, the display 131 is displayed from the passerby). The guide device 13) arranged at a visible position may be configured to display information in a display mode according to an attribute specified for the passerby.

As a method for the information display system 1 to identify the position of each passerby, for example, as adopted in the above-described embodiment, a method of recognizing a passerby from an image taken by a camera, or a method carried by a passerby. Examples thereof include, but are not limited to, a method of receiving and using position information transmitted from a terminal device (one provided with a positioning device such as GNSS).

(9) In the above-described embodiment, it is estimated whether or not a passerby who has entered the area P has left the area P based on the elapsed time after entering the area P. The method of estimating or determining whether or not a passerby who entered the area P has left the area P is not limited to this.

For example, if the destinations of trains departing from area P are always the same, and if the time normally required for a passerby to move to the boarding gate after entering area P is T, then the departure time of the last train from the entry time It is estimated that passers-by whose time to exceed T have already boarded the train and left Area P. Therefore, the server device 15 receives data indicating the train departure time from the higher-level system, and records the passersby whose time from the entrance time to the departure time of the last train exceeds T in the passerby table (FIG. 5). You may delete it from.

Further, when a passerby uses a magnetic ticket when passing through the automatic ticket gate 11, and the station name of the destination is recorded on the magnetic ticket, the server device 15 is the last train heading for the destination from the entry time. The record of a passerby whose time until the departure time exceeds T may be deleted from the passerby table (FIG. 5).

Further, the information display system 1 is provided with a camera for photographing a passerby who gets on the train or a passerby who passes through the automatic ticket gate 12 and exits from the area P, and the server device 15 is provided with images taken by those cameras. The recognized passerby record may be deleted from the on-site passerby table (FIG. 5).

Further, for example, the server device 15 continuously receives the position information from the terminal device carried by the passerby, and the record of the passerby whose position indicated by the received position information is not in the area P is stored in the passerby table (FIG. 5). ) May be deleted.
