Description

  The present invention relates to a system for allowing a user in a facility to check the present location with a very simple configuration, and a planar member with a two-dimensional code or NFC tag used therefor.

  In facilities such as stations, airports, large-scale commercial facilities, and theme parks, there is a need for facility users to confirm their current location. In recent years, abundant applications of portable terminals having a navigation function using GPS have been provided. Navigation using GPS can confirm the current location in a wide area, but it is difficult to discriminate between two relatively close points in the facility.

  As a current location confirmation system in the facility, access points equipped with a function for short-distance communication with mobile terminals are installed at various locations in the facility, and a management server connected to the access point and the network stores various information including current location information. Provided systems are known. However, such a system requires installation work of access point devices and on-site communication facilities in the facility, so that the installation cost is high and the installation, expansion and removal cannot be easily performed.

  A system using a two-dimensional code is also known as a system for performing a current confirmation in a facility relatively easily. For example, as disclosed in Patent Documents 1 and 2, it is well known that a two-dimensional code includes position information (coordinates, names, identification IDs associated with positions) of predetermined points. For example, if such a two-dimensional code is installed at the point, read the two-dimensional code with a mobile terminal and access an appropriate management server to obtain a map / guide map or other information of the point. Can be displayed on the mobile terminal.

  However, in the case of a system in which the two-dimensional code includes only the position information of the point as in Patent Document 1, even if a map or guide map of the current location is displayed on the mobile terminal, the user who is viewing the screen of the mobile terminal The direction of the body does not always match the direction of the displayed map or the like. The user may not know from which direction the displayed map or the like should be viewed.

  Patent Document 2 discloses a system having a function of determining in which direction a user of a mobile terminal is reading a two-dimensional code. The two-dimensional code in Patent Document 2 is provided so as to be displayed on the road surface. In the system of Patent Document 2, the information is read by imaging a two-dimensional code with a mobile terminal, and from which direction the user is reading the two-dimensional code is determined based on the captured image of the two-dimensional code. For this reason, the reference direction having a predetermined relationship with the specific pattern indicating the data arrangement direction normally included in the two-dimensional code is directed in the captured image, or displayed on the road surface in the vicinity of the two-dimensional code. In other words, the mobile terminal or the server application determines which direction the reference direction is oriented in the captured image. As the reference direction, the installation direction of the two-dimensional code may be included in the information of the two-dimensional code. The system of Patent Document 2 performs image processing for comparing the direction of a two-dimensional code in a captured image with a predetermined reference direction and calculating the orientation of the user's body from the difference in angle.

JP 2006-170872 A JP 2006-195913 A

  The system of Patent Document 2 is highly convenient because it determines the orientation of a user with a mobile phone and displays a guide map or the like in an appropriate orientation on the screen according to the orientation of the user. Since the two-dimensional code of Patent Document 2 is displayed on the road surface, the user may read the two-dimensional code from any direction on the horizontal plane 360 °. Therefore, in Patent Document 2, image processing for determining the orientation of the user with respect to the two-dimensional code based on the captured image is essential. Such image processing is performed by a portable terminal or a server, but complicates the application, requires processing time, and increases the system load.

  Moreover, since the system of Patent Document 2 displays a two-dimensional code on the road surface, a structure having a predetermined strength is required, and it can be said that it is difficult to perform installation and removal extremely easily.

  In view of the above-described problems, the present invention can more easily confirm the current location in the facility than the system in Patent Document 2, and can be easily installed, expanded, and removed at low cost. It is an object of the present invention to provide a current location confirmation system and a planar member with a two-dimensional code used therefor. Furthermore, a flat member with an NFC tag having an equivalent role in place of the two-dimensional code is also provided.

In order to achieve the above object, the present invention provides the following configurations.
According to a first aspect of the present invention, there is provided a current location confirmation system having a server capable of communicating with a mobile terminal possessed by a user via a communication network in order to allow a user in the facility to confirm the current location. And a plane member for confirming the present location attached on the vertical plane facing in a predetermined direction, and the surface of the plane member includes information indicating the position of the vertical plane in the facility and the vertical plane. A two-dimensional code or NFC tag including at least information indicating a direction and access information to the server is attached, and the server indicates information indicating a position in the facility and predetermined guidance related to the position. A database pre-stored in association with a figure, and the position read and read from a portable terminal that has read the two-dimensional code or NFC tag of the planar member Means for receiving a report and information indicating the direction, means for acquiring a corresponding guide map by referring to the database based on the received information indicating the position, and information indicating the received direction And a means for determining a direction for displaying the acquired guide map, and a means for transmitting the acquired guide map to the portable terminal to display the guide map according to the determined orientation. .

  In the above system, it is preferable that the planar member is a flexible sheet or an inflexible plate made of paper or plastic.

  In the above system, when a two-dimensional code is attached to the planar member, it is preferable that the two-dimensional code is attached to the surface of the planar member by printing or pasting.

  Another aspect of the present invention is a plane member for confirming the present location for being attached to a vertical plane facing a predetermined direction in a facility for use in the system, and is attached to the surface of the plane member. The two-dimensional code or NFC tag, the two-dimensional code or NFC tag includes information indicating the position in the facility of the vertical surface to which the planar member is attached, and the direction of the vertical surface to which the planar member is attached. And at least information indicating access to the server.

  The present location confirmation system according to the present invention uses a planar member having a surface with a two-dimensional code for confirming the present location, and the planar member with the two-dimensional code is attached on a vertical surface facing a predetermined direction in the facility. The This two-dimensional code includes information indicating the position of the vertical plane in the facility and information indicating the direction of the vertical plane. A user who wants to read the two-dimensional code should read the camera of the portable terminal toward the two-dimensional code with almost 100% of the user facing the vertical plane. This is a natural attitude from an ergonomic point of view. Therefore, the information indicating the direction of the vertical plane included in the two-dimensional code indicates the orientation of the user's body at that time. Actually, since the user faces the vertical plane, the direction of the user's body is 180 degrees opposite to the vertical plane. For example, if the vertical plane is facing north, the user is facing south.

  A configuration in which a planar member with an NFC tag in which the two-dimensional code is replaced with an NFC tag and a portable terminal having an NFC tag reading function also has the same effect as described above. This is because the user should read the information by holding the portable terminal over the NFC tag while facing the flat member with the NFC tag.

  As a result, in the system of the present invention, the information included in the two-dimensional code or the NFC tag becomes the information indicating the orientation of the user's body as it is, so that the two-dimensional code is based on the photographed image of the two-dimensional code as in Patent Document 2. A process for comparing the direction of the cord with the reference direction and determining the current body direction of the user is not necessary. As a result, the application can be simplified and the processing load on the system can be reduced.

  Furthermore, since a guide map or the like can be displayed in an appropriate orientation on the screen of the mobile terminal according to the orientation of the user's body, the convenience is high.

  In addition, the two-dimensional code or the NFC-tagged planar member used in the system of the present invention is preferably a flexible sheet or non-flexible plate made of paper or plastic. In the case of a two-dimensional code, for example, it is only printed or pasted on a paper poster, and in the case of an NFC tag, it is only pasted. As a result, the planar member used in the system of the present invention can be easily installed, expanded and removed from a wall, a pillar, etc., and equipment installation work such as an access point in the conventional current location confirmation system is completely unnecessary. In addition, NFC tags that are more expensive than two-dimensional codes are now provided at a relatively low cost. Therefore, this system can be implemented at a very low cost.

FIG. 1 is a perspective view showing a planar member with a two-dimensional code for confirming the current position used in the present position confirmation system according to the present invention. FIG. 2 is another example of the orientation of a two-dimensional code that includes the same information as that of FIG. FIG. 3 is a schematic perspective view showing an example in which the planar member shown in FIG. 1 is applied to two vertical surfaces having different directions at one same position in the facility. FIG. 4 is a diagram schematically showing a configuration example of the current location confirmation system according to the present invention. FIG. 5 shows a configuration example of the database 3f shown in FIG. FIG. 6 is a flowchart schematically showing an example of the execution flow of the present system.

  Hereinafter, a current location confirmation system according to the present invention will be described in detail with reference to the drawings showing a configuration example of an embodiment of the present invention. In addition, in each drawing, the same or similar code | symbol is attached | subjected about the common or similar component.

  In the following, the present invention will be described by taking an embodiment using a two-dimensional code as an example. However, the present invention can be similarly implemented even when an NFC tag is used. The NFC tag is used in short-range wireless communication technology based on the Near Field Communication standard which is an international standard. An IC chip built in the NFC tag includes a short-range non-contact communication function and a storage unit capable of storing predetermined information. Recently, a portable terminal such as a smart phone having an NFC tag reading function has become common.

  FIG. 1 is a perspective view showing a planar member with a two-dimensional code for confirming the current position used in the present position confirmation system according to the present invention. The planar member 10 has a base material 11 and a two-dimensional code 12 printed or pasted on the surface thereof.

  As an example, the base material 11 is a paper sheet or a plastic sheet, and is flexible and can be bent or curved. The base material 11 may be provided with only the two-dimensional code 12, but may be a poster or a display that displays various contents in a space other than the two-dimensional code 12. As another example, the base material 11 may be a thin plate made of non-flexible paper, wood, or plastic having a thickness that cannot be folded. The material and thickness of the base material 11 are not limited to these, and any material having a flat surface to which a two-dimensional code can be attached may be used. The surface area of the base material 11 should just be the magnitude | size which can attach | subject the two-dimensional code 12 to the minimum. The outline shape of the base material 11 is not limited to the illustrated rectangle, and is arbitrary.

  The planar member 10 is attached to a predetermined vertical plane in the facility. The vertical surface in the facility is a flat surface extending in the vertical direction, such as a side surface of walls, fences, doors, columns, partitions, etc., and a side surface of facilities / equipment. When the planar member 10 is attached to the vertical plane, the surface of the planar member 10 extends along the vertical plane. In FIG. 1, the vertical direction is indicated by a black arrow V. Attaching means to the vertical surface of the planar member 10 is optional, such as sticking with an adhesive or fixing with a fixture such as a pin.

  The two-dimensional code is, for example, a QR code (registered trademark), but is not limited thereto. The two-dimensional code includes information indicating where the vertical surface to which the planar member 10 is attached is located in the facility, information indicating to which direction the vertical surface to which the planar member 10 is attached, and the server. Access information.

  The information indicating the position of the vertical plane can uniquely identify the position in the facility, such as the coordinates of the position, an ID uniquely assigned to the position, a name unique to the position, and the like.

  The direction of the vertical plane means the direction of the normal of the vertical plane. This is a predetermined orientation in a horizontal plane such as east, west, south, north, and the like. The direction of the planar member 10 naturally matches the direction of the vertical plane to which it is attached. In FIG. 1, the direction of the vertical plane is indicated by a white arrow H. The information indicating the direction of the vertical plane is uniquely assigned to one direction, such as the name of the direction and the identification ID indicating the direction. For example, when the direction of the vertical plane is “north”, the information indicating the direction of the vertical plane may be expressed as “north” or “N” as it is, or “right is east and left is west”. . Alternatively, the direction of the vertical plane may be replaced with the direction of the user so that “left is east and right is west”. These are all regarded as information indicating the direction of the vertical plane.

  Note that the information indicating the direction of the vertical plane included in the two-dimensional code is not information indicating the direction of the two-dimensional code 12 itself in the plane, and is irrelevant to the direction of the two-dimensional code 12 itself. This is a significant difference between the present invention and Patent Document 2. For example, when the contour of the planar member 10 is circular as shown in FIG. 2, the two-dimensional code 12 (including the same information as the two-dimensional code 12 of FIG. 1) is inclined in the vertical plane depending on how the planar member 10 is attached. there is a possibility. However, in the present invention, the direction of the two-dimensional code 12 in the captured image when reading the two-dimensional code 12 (the direction in the vertical plane) is completely irrelevant to the subsequent processing. In both the case of FIG. 1 and FIG. 2, it is sufficient that the information included in the two-dimensional code 12 can be read. The two-dimensional code reading application provided in the current general portable terminal can read the same information from the two-dimensional code 12 shown in FIGS. 1 and 2 without any trouble.

  The server access information is typically a URL of a website provided by the server application.

  FIG. 3 is a schematic perspective view showing an example in which the planar member 1 shown in FIG. 1 is applied to two vertical surfaces having different directions at one same position in the facility.

  The two vertical planes shown in FIG. 3 are one side 91 of the pillar 9 in the facility and the side 92 on the opposite side. As described above, the adjacent vertical planes within a predetermined distance are considered to be at the same position, and the information indicating the position is the same. The direction of the side surface 91 is “south” indicated by the white arrow S, and the direction of the side surface 92 is “north” indicated by the white arrow N. Therefore, the two-dimensional code 12S of the planar member 1S attached to the vertical surface 91 includes information indicating the position of the pillar 91 in the facility and information indicating the direction “south”. On the other hand, the two-dimensional code 12N of the planar member 1N attached to the vertical surface 92 includes information indicating the position of the pillar 91 in the facility and information indicating the direction “north”.

  FIG. 3 also shows the portable terminal 2 possessed by the user when reading the two-dimensional codes 12S and 12N, respectively. The mobile terminal 2 is, for example, a smart phone, a mobile phone, a tablet, a notebook personal computer, or the like. In the illustrated example, an example of a smart phone is shown, which includes a display 21 and a camera 22. A two-dimensional code reading application provided in a general portable terminal captures a two-dimensional code with the camera 22 and decodes the captured image to read information. Further, for example, when a URL is read, it is displayed on the display 21.

  In the illustrated example, the portable terminal 2 reading the two-dimensional code 12S takes a posture along the vertical direction, but the portable terminal 2 reading the two-dimensional code 12N takes a tilted posture. ing. In the present invention, the posture of the portable terminal 2 may be any posture as long as the two-dimensional codes 12S and 12N can be read. The present invention is based on an ergonomically reasonable assumption that in any case the user's body will be generally facing the vertical plane 91,92. This is also different from Patent Document 2. In Patent Document 2, since the user's orientation is determined based on the orientation of the captured image, the user's orientation determined differs depending on the orientation of the mobile terminal. On the other hand, the present invention only needs to read information contained in the two-dimensional codes 12S and 12N, and the direction of the two-dimensional code in the captured image is irrelevant to the subsequent processing.

FIG. 4 is a diagram schematically showing a configuration example of the current location confirmation system according to the present invention.
This system includes a mobile terminal 2 and a facility information server 3 that can be connected to the mobile terminal 2 via a communication network 4.

  The portable terminal 2 can have various forms as described above, but is basically a portable computer into which a program for realizing a predetermined function is introduced. An operating system and a predetermined application program are installed, and the CPU reads and executes it in the memory, thereby functioning as a portable terminal having the functions of the processing units of the present invention. Similarly, the facility guidance server 3 is a computer that has an operating system and a predetermined application program installed therein, and is loaded into the memory and executed by the CPU, thereby providing a server device having the functions of the processing units of the present invention. Function.

  A case where the mobile terminal 2 is a smartphone will be described as an example. As a main function, the portable terminal 2 performs a two-dimensional code reading process in cooperation with a control unit 2a that links and controls each processing unit, an input unit 2b that is a touch panel, and a camera (see FIG. 3). A dimension code reading unit 2c, a web browser 2d for browsing a website, a display unit 2e for performing display processing on the display 21, and a transmission / reception unit 2f for performing transmission / reception via an appropriate communication network 4 Have. The processing units for these functions are basically provided for general smartphones.

  The server 3 includes, as main functions, a control unit 3a that links and controls the processing units, a web server function 3b that also includes a transmission / reception function with the mobile terminal 2, and information on the current location and direction transmitted from the mobile terminal 2. A processing unit 3c that performs processing at the time of acquisition, a processing unit 3d that performs processing at the time of acquiring destination information transmitted from the portable terminal 2, and guidance information regarding the current location and destination transmitted to the portable terminal 2 are created. And a processing unit 3e that performs processing.

  Further, the server 3 has a database 3f for appropriately storing information related to the present system in advance or during operation.

FIG. 5 shows a configuration example of the database 3f shown in FIG.
The vertical plane information table with a two-dimensional code shown in FIG. 5A pre-registers information about the vertical plane with the two-dimensional code-added plane member shown in FIG. The data items include “position ID”, “direction”, and “location name”. “Position ID” registers an identification number uniquely assigned to one or more vertical planes at one position. “Direction” registers information indicating each direction of one or more vertical surfaces at one position. The direction is not limited to east, west, south, and north. The “location name” registers a specific name of the location where the vertical plane is located.

  The first record in the example of FIG. 5A is registered when, for example, flat members are attached to the four sides of the pillar located at the domestic departure counter on the first floor of the facility whose position ID is “1001”, respectively. Information. The second record is registration information when, for example, a plane member is attached to each of the east and west surfaces of the wall located at the domestic arrival port on the first floor of the facility whose position ID is “1002”.

  In the position / guide map correspondence table in FIG. 5B, the position ID and a predetermined guide map including the location of the vertical plane of the position ID are registered in advance in association with each other. The data items include “position ID”, “guide map name”, and “link to guide map file”. “Position ID” is linked to “Position ID” in the table of FIG. “Link to guide map file” is information indicating a place in the storage device in which the guide map file is stored.

  In the example of FIG. 5B, one guide map “first floor guide map” is associated with all the vertical planes (position IDs) included in the first floor of the facility. Further, one guide map “second floor guide map” is associated with all the vertical planes (position IDs) included in the second floor of the facility. This is an example, and each floor may be divided into a plurality of sections and a guide map for each section may be provided.

  The user current location / destination table in FIG. 5C is a dynamic table recorded when the user uses the system during operation. The data items include “user ID”, “current position ID”, “current direction”, and “destination position ID”. As the “user ID”, for example, when the facility information server 3 is accessed from the mobile terminal 2, the user ID is assigned based on the unique terminal identification information included in the communication from the mobile terminal 2. “Location ID of current location” records the location ID of the two-dimensional code information received from the mobile terminal 2. This position ID is linked to the position ID shown in FIGS. “Current direction” records the direction in the two-dimensional code information received from the mobile terminal 2. This direction is linked to the direction of FIG. “Destination position ID” records a position ID corresponding to information indicating the destination received from the mobile terminal 2. This position ID is also linked to the position ID shown in FIGS.

  FIG. 6 is a flowchart schematically showing an example of the execution flow of the present system. In the description, reference may be made to FIGS.

  First, a user who wants to confirm the current location stands in front of a vertical surface (for example, the side surface 91 of the pillar 9 in FIG. 3) provided with the planar member 1 with a two-dimensional code, and uses the portable terminal 2 to obtain the two-dimensional code 12. Read (step S11). The two-dimensional code 12 includes a URL for accessing the facility guidance server 3 and information indicating the position ID and direction of the vertical plane of the current location. The portable terminal temporarily stores information indicating the read position ID and direction.

  Next, the facility guidance server 3 is accessed from the portable terminal 2 using the read URL (step S12). When a predetermined login is performed, the website provided by the facility information server 3 is displayed on the display 21 of the portable terminal. At the time of login, the user-specific information of the portable terminal 2 and the information indicating the position ID and direction of the vertical plane read from the two-dimensional code are also automatically transmitted to the facility guidance server 3.

  The facility guidance server 3 accepts login from the portable terminal 2 and receives information indicating the unique information of the portable terminal 2, the position ID of the vertical plane, and the direction (step S13). Subsequently, a user ID corresponding to the unique information of the portable terminal 2 is assigned, a new record is created in the user current location / destination table (FIG. 5C) of the database, and the user ID and the vertical plane position ID are stored.

  In this example, the facility information server 3 has a multilingual function. Therefore, the facility guidance server 3 transmits a language selection screen to the mobile terminal 2 (step S14).

  A language selection screen is displayed on the display of the portable terminal 2 (step S15).

  When selection of a desired language is input by the user in the portable terminal 2, language selection information is transmitted to the facility guidance server 3 (step S16).

  The facility information server 3 that has received the language selection information sets the subsequent website display based on the selected language. Subsequently, the facility information server 3 refers to the position / guide map correspondence table (FIG. 5B) in the database based on the position ID acquired in step S13, and acquires the corresponding guide map (step S17). .

  Subsequently, the facility guidance server 3 determines the direction in which the guidance map acquired in step S17 is displayed based on the information indicating the direction acquired in step S13 (step S18). For example, if the information indicating the direction of the vertical plane is “south”, the user is assumed to face the vertical plane and face “north”. Accordingly, the guide map is determined so that the top is “north” (that is, the right is east and the left is west).

  Next, the facility guidance server 3 transmits a guidance map to the mobile terminal 2 so that the facility map is displayed in the determined direction (step S19). In this example, at this time, a destination selection screen is also transmitted together with the guide map and displayed simultaneously. This is because most users who check the current location aim to guide the destination from the current location. For example, the guide map is displayed in the upper half of the screen, and the destination selection screen is displayed in the lower half. Alternatively, the guide map is displayed on the entire screen, and a switching button for switching the display to the destination selection screen is displayed on the screen.

  As a result, a guide map around the current location is displayed in a predetermined direction on the display 21 of the portable terminal 2 (step S20). Thereby, the user can see the guide map around the current location in the correct orientation with the posture facing the vertical plane. When the vertical plane in front of the user is a wall, the user often looks back and confirms the guide map with the wall behind. In that case, if a button having a function of rotating the screen by 180 ° is provided in the display screen, the user can rotate the screen.

  When the destination selection screen is displayed on the display 21 of the mobile terminal 2, the user inputs a destination selection. The portable terminal 2 transmits the position ID corresponding to the selected destination to the facility guidance server 3 (step S21).

  The facility guidance server 3 acquires the location ID of the destination. Based on the destination position ID, the position / guide map correspondence table of FIG. 5B is referred to, and the corresponding guide map is acquired (step S22). If the acquired destination map is the same as the current location guide map acquired in step S17, that is, if the destination is close to the current location, the destination map is shown in the currently displayed guide map. After an easy-to-understand sign is added, it is transmitted to the portable terminal 2. A sign indicating the destination is displayed on the portable terminal 2 (step S23). The sign is, for example, an arrow indicating a direction from the current location, a line indicating a route, a mark blinking at a destination point, or the like.

  Further, when the destination guide map acquired in step S22 is different from the current location guide map acquired in step S17, that is, when the destination is relatively far from the current location, the destination guide map is displayed on another screen or the like. To the mobile terminal 2 (step S23).

  It is preferable that the screen displayed on the portable terminal 2 in step S23 includes various guidance signs (such as route descriptions and arrows) that guide the user to the destination.

  Thereafter, the user moves to the destination according to the guidance on the displayed screen. If the route becomes unknown again during the movement, the current location may be confirmed again using a plane member with a two-dimensional code attached to the nearest vertical plane.

  The planar member with a two-dimensional code used in this system can be manufactured at a very low cost and can be attached very easily. The cheapest example is paper on which a two-dimensional code is printed. Therefore, a large number of two-dimensional code-attached planar members can be easily attached anywhere in the facility.

  Although the present location confirmation system using the two-dimensional code has been described above, in the case of using the NFC tag, the NFC tag is attached to the surface of the flat member attached to the vertical surface by pasting the NFC tag, and the mobile terminal uses the NFC tag. It has a reading function. Similarly to the above-described two-dimensional code, the NFC tag also includes information indicating the position of the vertical plane, information indicating the direction of the vertical plane, and information for accessing the server. Other configurations in the case of using the NFC tag are the same as in the case of using the above-described two-dimensional code.
