Description

  The present invention relates to a guidance system using a mobile terminal.

  A system that uses GPS (Global Position (Positioning) System) installed in mobile terminals, etc., to acquire the position of the mobile terminal and provide guidance services such as providing peripheral information and directions to the destination is put into practical use. Has been.

  On the other hand, in order to realize the same service indoors where GPS cannot be used, another mechanism is required to acquire the position of the mobile terminal. A system having such a mechanism can be classified into a system in which a mobile terminal mainly detects a position and a system in which a terminal position is detected on the network system side.

  In the former system, IDs (identifiers) are assigned to indoor places, and the ID around the mobile terminal is detected and specified by an ID reader mounted on the mobile terminal side.

  In the latter system, an ID that can be read from the surroundings is assigned to the mobile terminal, and the network system recognizes the position of the mobile terminal by ID readers disposed in various places indoors.

  In order to realize the latter system, it is necessary to arrange ID readers at various locations in the room and to construct a network that connects them. Since the latter system generally has a high construction cost, the former system is more feasible.

  In the former system, the mobile terminal needs to have an ID reader. As IDs to be used, RFID (Radio Frequency Identification), wireless LAN (Local Area Network) base station IDs, image IDs that can be obtained by image processing of camera images (visual tags, digital watermark IDs, character string recognition) Character string obtained).

  However, existing mobile phones do not have a reader device for acquiring RFID or wireless LAN base station ID. It is possible to recognize an image ID posted in the vicinity using a camera built in the mobile phone. However, it is necessary for the user to sequentially activate the camera and execute the recognition process, and the use operation becomes complicated. Further, as a method for lowering costs (for example, see Patent Document 1), a system for specifying a location using a key manually input by a user without using an ID reader has been proposed.

However, the user's line-of-sight direction (destination direction) cannot be detected using any ID. The user's line of sight plays an important role in improving the user interface of the guidance service. For example, in a navigation system using GPS capable of detecting the traveling direction, a map is displayed on the screen so that the traveling direction is on the top, so that the user can easily understand the relationship between the real space and the map.

  Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.

  A basic configuration of the guidance system in the present embodiment will be described with reference to FIG. The guidance system in the present embodiment uses a predetermined number of character strings as IDs, circular ID marks 1, portable terminal devices (designed so that each character constituting the ID is circularly arranged and each character indicates a direction ( Hereinafter, it can be configured with 2 and server device 3. For example, a server computer equipped with a CPU (Central Processing Unit) can be used as the server device 3. As the mobile terminal 2, any terminal device (terminal device equipped with a CPU) including a mobile phone can be used. In the following description, a mobile terminal is assumed.

  The server device 3 includes at least an ID input unit 3b for receiving an ID from the portable terminal 2, a position / direction detection unit 3c, and a position / direction ID management table 3f having position / direction ID management data. Depending on the content of the service to be provided, each unit can be provided with a guidance information providing unit 3e, a content information management table 3g having content information management data, a destination designating unit 3a, and a route direction determining unit 3d.

  The guidance server device according to the present embodiment refers to the server device 3 that constitutes the guidance system. The portable terminal 2 and the server device 3 are assumed to include a general-purpose storage unit (for example, a memory or a hard disk device) that stores data necessary for processing in the present embodiment. The portable terminal 2 is assumed to include input / output means 2a such as a Web browser. The input / output means 2a may be dedicated communication software according to the present embodiment.

  Although not shown, when the position / direction ID management table 3f is provided, the position / direction ID management means for managing the position / direction ID management table 3f and the content information management table 3g are used for content information management. It is assumed that content information management means for managing the table 3g is provided.

  The server device 3 constituting the guidance system in this embodiment includes a position / direction detection means 3c, and a position / direction ID management table that associates a character string in which a predetermined number of characters on each circular ID mark are arranged in a predetermined order with the position / direction. 3f. When the user receives, as an ID, a character string in which a plurality of characters on the circular ID mark 1 are input in a predetermined order, the position / direction detection means 3c refers to the position / direction ID management table 3f, and the user The position and line-of-sight direction of the mobile terminal 2 are detected.

  The position / direction ID management table 3f associates a position with a character string in which a predetermined number of characters on the circular ID mark 1 are arranged in a predetermined order, and the character string includes the first character of the character string. Corresponds to the direction indicated on the annular ID mark 1.

  For example, the character string arranged in the clockwise order from the upper character on the circular ID mark 1 when viewed from an arbitrary direction is associated with the position, and the first character of the character string is the character string. The directions shown on the annular ID mark 1 are associated with each other.

  As a result, when the user inputs each character in the clockwise order from the character on the upper part of the circular ID mark 1 as viewed from the user's point of view, the user selects the circular ID from which direction according to the input character string. Whether the mark 1 is seen (the direction of the line of sight) can be determined.

  The server device 3 of the guidance system according to the present embodiment further includes guidance information notification means 3e and a content information management table 3g for associating content information with a location in order to realize a peripheral information providing service to the user.

  After the position / direction detection unit 3c detects the position and line-of-sight direction of the user's mobile terminal 2, the guidance information notification unit 3e refers to the content information management table 3g and detects content information around the detected position. To do. Then, in order to make it easier for the user to grasp the positional relationship between the real space and the content information, peripheral content information is created in which the direction in which each content information is located is indicated by the characters on the circular ID mark 1, and the peripheral content information Is transmitted to the portable terminal 2. The guidance information notification unit 3e configures the peripheral content information based on the detected line-of-sight direction.

After the position / direction detection unit 3c detects the position and line-of-sight direction of the user's mobile terminal 2, the route direction determination unit 3d sets in advance from the position based on the detected position of the user's mobile terminal 2. The route direction for reaching the destination is determined by a predetermined method.

  Next, in order to make it easier for the user to grasp the route direction, the guide information notifying means 3e includes the route direction information including characters on the annular mark 1 and indicating the direction corresponding to the route direction. Is transmitted to the portable terminal 2.

  Then, in order to simultaneously realize the peripheral information providing service and the navigation service, the guide information notifying unit 3e transmits the peripheral content information to the mobile terminal 2 simultaneously with the route direction information. The guidance information notification unit 3e configures the peripheral content information based on the determined route direction.

  A configuration example of the annular ID mark used in the guidance system in the present embodiment will be described with reference to FIGS.

  The annular ID mark 1 in FIG. 2 and the annular ID mark 11 in FIG. 3 are premised on use with a mobile phone, and can be input with a numeric keypad (dial key) of the mobile phone. Using the characters “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, “*” (asterisk), “#” (sharp) The ID is configured. Note that the number of characters constituting the ID may be different for each circular ID mark.

  The circular ID mark is designed such that each character constituting the ID is arranged in a circular shape and each character indicates a direction. Each character is arranged so that the outside of the circle is on the top. That is, the annular ID mark is not assumed to be viewed from a specific direction, but may be viewed from any direction around the annular ID mark.

  For example, an annular ID mark 1 in FIG. 2 shows an example of an annular ID mark when an ID is composed of four characters (“1”, “2”, “3”, “#”). The circular ID mark 11 in FIG. 3 comprises an ID with eight characters (“0”, “1”, “3”, “5”, “7”, “9”, “*”, “#”). The example of the cyclic | annular ID mark in the case of doing is shown. In either case, the same character is not included in one ID. With this configuration, one character indicates one direction on the annular ID mark.

  As described above, the number of characters constituting the ID presented on the annular ID mark may be any number as long as it is one or more characters. For example, in the following description, a case where the ID is composed of 4 characters is described.

  However, it is also possible to use IDs other than four characters in the guidance system in this embodiment. For example, four-character IDs “1”, “2”, “3”, “#” are two-character IDs “1”, “2”, “1”, “2”, “3”, It is also possible to use 8-character IDs of “4”, “5”, “6”, “7”, “8”.

  When there are at most two directions to be indicated by the annular ID mark, an annular ID mark including an ID with two characters can be used. On the other hand, there are eight directions in which a circular ID mark should be indicated at a point that branches in eight directions. In this case, a circular ID mark including a two-character ID can be used. That is, the number of characters is a characteristic that makes the ID unique.

  The guidance system in the present embodiment determines an ID for identifying one point by uniquely determining the number of characters, the order in which the characters are arranged, and the three elements of the included characters.

  “0”, “1”, “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, “*”, “#” When 12 characters are used, the number of points that can be identified by the ID of N characters is given by the equation (12! / ((12-N)!) / N.

  There are 12 types of permutations composed of 12 different N characters! / (12-N)! It becomes. Furthermore, since they are arranged circumferentially, N types of permutations obtained by cyclically shifting each character of the N character permutations indicate the same point. As a result, IDs for identifying (12! / ((12-N)!) / N different points can be determined, for example, 12 points for 1 character ID, 66 points for 2 characters, 440 for 3 characters. A point can identify 2970 points with 4 characters, 19008 points with 5 characters, 110880 points with 6 characters, 570240 points with 7 characters, and 2494800 points with 8 characters.

  For example, when the server apparatus 3 of this embodiment is installed in each facility such as an exhibition hall, a museum, and an art museum and the guidance service is performed, the number of circular ID marks (that is, depending on the size of the facility) The number of points to be identified is predicted to be about 1000 at most. Therefore, even a 4-character ID is sufficiently practical. In addition, even when an ID of 3 characters or less is used, an ID can be assigned to 12 + 66 + 440 = 518 points, and many facilities can be supported.

  On the other hand, in order to realize a guidance service in a plurality of facilities and areas throughout the country using one server device 3 in the present embodiment, the number of identifiable points is small. Therefore, the server device 3 according to the present embodiment uses the active current location area instruction operation of the user, or the GPS of the mobile terminal 2 or the base station ID at the time of communication, in which the mobile terminal 2 exists. There may be a means for selecting the position / direction ID management table 3f and the content information management table 3g according to the facility.

  For example, the annular ID mark is added to the floor surface by being printed directly on the floor surface or printed on a sheet that can be attached to the floor surface. Further, advertisement information can be further attached around the area where the annular ID mark is printed, and a so-called floor advertisement and the annular ID mark can be combined. It may be engraved on the floor and an annular ID mark may be attached. It may be in the form of presentation on the floor using a projector or other optical device from the ceiling. For example, the annular ID mark may be presented on the floor surface by attaching an object or film for forming a shadow corresponding to the annular ID mark directly below the lighting fixture that illuminates the floor surface from the ceiling.

  In the present embodiment, it is assumed that the annular ID mark is presented (provided) on the floor, but may be presented on a wall surface, ceiling, table, or the like.

  An outline of the operation of the guidance system in this embodiment will be described with reference to FIG. In the following description, the description of the same reference numerals as in FIG. 1 is omitted.

  In the guidance system, a plurality of the annular ID marks 1 each having a different ID are arranged in a space to be guided (that is, a space where guidance information is to be provided). Basically, as shown in FIG. 5, each letter on the annular ID mark is arranged at the branch of the passage so as to indicate the direction of each branch to be branched. That is, in FIG. 5, the upward direction is “1”, the downward direction is “3”, the right direction is “2”, and the left direction is “#”.

  The user U inputs the characters on the circular ID mark 1 to the portable terminal 2 in a predetermined order based on the viewpoint of the user at each point where the circular ID mark 1 is arranged. For example, the user inputs a plurality of characters on the circular ID mark in the clockwise order from the character positioned above the circular ID mark when viewed from the user.

  For example, for the circular ID mark 1 including four characters shown in FIG. 2, “123 #” id1 in the line-of-sight direction A and “1” in the line-of-sight direction B, as shown in FIG. 23 # 1 ”id2, ID“ 3 # 12 ”id3 in the line-of-sight direction C, and“ # 123 ”id4 in the line-of-sight direction D are input. Conversely, the input may be in the order of counterclockwise rotation.

  In order to prompt such an input operation, the guidance system assumes an ID input screen that the ID input unit 3b of the server device 3 presents to the mobile terminal (mobile phone) 2 when using the guidance system in the present embodiment. Information for instructing the user U to input order may be presented. For example, FIG. 7A shows an ID input screen instructing to input characters in the clockwise order (in the direction of arrow α in FIG. 7A) from the character above the ring ID mark.

  Then, as a basic procedure thereafter, the mobile terminal 2 transmits the input character string as an ID to the server device 3 via a predetermined communication line (for example, the network 100), and the server device 3 receives the ID. The processing is performed based on the above, and the guidance service is provided to the portable terminal 2.

  Note that the present invention can be realized by configuring some or all of the functions of each means in the guidance system and guidance server device of the present embodiment with a computer program and executing the program using the computer. It goes without saying that the procedure of the guidance method in the guidance system and the guidance server device according to the embodiment can be constituted by a computer program, and the program can be executed by the computer.

  As described above, according to the present embodiment, in order to reduce the construction cost and to access the guidance service with a simple operation, the characters “0”, “1”, Marks including IDs consisting of “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, “*”, “#” are placed indoors. This is a guidance system that provides a guidance service by using the floor.

  Further, as the mark, a plurality of different character strings are regarded as IDs, each character constituting the ID is arranged in a ring shape, and a circular ID mark designed so that each character indicates a direction is used. It is said.

  When each character is input in the clockwise order from the characters described in the upper part on the circular mark as viewed from the user's viewpoint, the input ID varies depending on the direction from which the user views the circular ID mark. . Using this point, the guidance system in the present embodiment detects the user's line-of-sight direction.

  The guidance system in the present embodiment constructs output information using the detected line-of-sight direction, and uses the characters on the annular ID mark as an instruction symbol for direction guidance, so that the real space and the guidance information are The relationship can be easily understood by the user.

  It can be used by any portable terminal having a data communication function.

  In particular, “0”, “1”, “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, “*”, “#” By constructing an ID from characters, it can be easily used from a mobile phone using only a numeric keypad as input means.

  Because of these characteristics, the guidance system in the present embodiment realizes a guidance service for mobile phones indoors at low cost.

  Further, the present embodiment detects the position and the line-of-sight direction of the mobile terminal user, and can be applied to any service realized using the user position and the line-of-sight direction. For example, a service similar to a pedestrian navigation service provided for a mobile phone having GPS and a direction detection function can be realized by using the method, apparatus, and system in this embodiment.

  The operation of each means of the server device of the guidance system according to the present embodiment will be described in detail below by giving specific guidance service examples.

[Example 1]
The server device in the guidance system according to the first embodiment is realized using a Web server connected to the Internet. In the following description, the same reference numerals as those in FIGS. 1 and 4 are omitted.

  Each means of the server device 3 can be implemented using a web application development system such as HTML (HyperText Markup Language), PHP (PHP: HYPERTEXT Preprocessor), Perl, Ruby, Servlet, or the like. Further, the guidance service provided by the server device 3 can be used by the mobile terminal 2 having a Web browser.

  In the first embodiment, the operation of the guidance system will be described by taking as an example a peripheral content information providing service that is provided to the mobile terminal 2 that includes the server device 3 as a Web server and has a Web browser. In the following explanation, an ID is composed of four characters, and the user inputs the four characters on the circular ID mark in order from the character positioned above the circular ID mark in the clockwise direction. Shall be allowed to.

  In the peripheral content information providing service, the server device 3 includes an ID input unit 3b, a position / direction detection unit 3c, a position / direction ID management table 3f, a guidance information notification unit 3e, and a content information management table 3g.

  The peripheral content information providing service method will be described with reference to FIG.

  First, a user accesses a URL (Uniform Resource Locator) of a server device via a Web browser of a mobile terminal.

  Next, the ID input means 3b provides the ID input screen shown in FIG. 7A to the Web browser. When the user U arrives at the position where the circular ID mark 1 is installed, the user U inputs the character string on the circular ID mark 1 in the order described above to the ID input screen, and selects the search button P1.

  Then, the ID input unit 3b regards the input character string as an ID and transmits it to the position / direction detection unit 3c of the server device 3.

  A configuration example of the position / direction ID management table 3f will be described with reference to FIG. The position / direction ID management table 3f includes position / direction ID management data including a serial number field F11, an ID field F12, a position information field F13, a direction information field F14, and a route end point position information field F15.

  The ID field F12 holds all ID values that may be transmitted from the portable terminal 2.

  The position information field F13 holds information indicating the position corresponding to each ID. That is, the position of the annular ID mark 1 having the ID is held. For example, the position information may be expressed using (latitude, longitude, altitude) or (latitude, longitude, floor number). In the case of implementation in a specific space, the reference coordinates of the space are set as the origin, and a predetermined distance (1 meter, 10 meters, etc.) is used as a unit, and expressed in the form of (x coordinate, y coordinate, z coordinate). Also good. In the example of FIG. 8, the position information is indicated by (x coordinate, y coordinate, floor number).

  The direction information field F14 is a field for indicating the line-of-sight direction. Vector information indicating the line-of-sight direction is held in the same coordinate system as the position information.

  The route end point position information field F15 indicates that there is a route from the position of the circular ID mark 1 indicated by the position information field F13 to the position indicated by the route end point position information field F15. On the other hand, when there is no route, the route end point position information field takes the same value as the corresponding position information or is blank (“Non” in FIG. 8). In addition, in order to make it possible to continuously use the plan information providing service using the circular ID mark 1 in the space to be guided by the user U, the position indicated by the route end point position information field F15 must be The guidance system is configured such that another annular ID mark 1 is arranged.

  When receiving the ID, the position / direction detection means 3c refers to the position / direction ID management table 3f, detects the position and line-of-sight direction of the user U, and transmits it to the guidance information notification means 3e. For example, when the position / direction detection unit 3c receives “123 #” as the ID, the position / direction detection unit 3c refers to the position / direction ID management table of FIG. 8, and “123 #” indicates the position of (5, 5, 1), and Confirm that the direction of the vector (0, -1, 0) is the line-of-sight direction. Then, the ID, the corresponding position information, and line-of-sight direction information are transmitted to the guidance information notification means 3e.

  The content information management table 3g is a table for managing content information linked to position information. An example of the configuration of the content information management table will be described with reference to FIG. The content information management table 3g shown in FIG. 9 has content information management data including a serial number field F21, a position information field F22, a URL field F23, a title field F24, an explanation field F25, and a telephone number field F26.

  The position information field F22 holds the position of each content information in the same format as the position information field F13 of the position / direction ID management table 3f described above.

  The URL field F23 stores the URL when the content information is on the Web.

  The content information management table 3g can also hold attribute information related to content other than the title, description, and telephone number.

  When the guidance information notifying unit 3e receives the position and line-of-sight direction of the user U from the position / direction detecting unit 3c, the guidance information notifying unit 3e refers to the position / direction ID management table 3f and the content information management table 3g to configure the peripheral content information.

  An example of a procedure for creating peripheral content information is shown below.

  First, the guidance information notification means 3e receives the ID “123 #” and the user position information (5, 5, 1) from the position / direction detection means 3c, and refers to the position / direction ID management table 3f. A route existing from the position (5, 5, 1) indicated by the ID of 123 # ”is extracted.

  That is, for each of four IDs indicating the position (5, 5, 1), that is, “123 #”, “23 # 1”, “3 # 12”, “# 123”, the route end point position information field F15 is set. 4 routes [(5, 5, 1), (5, 1, 1)], [(5, 5, 1), (6, 5, 1) starting from (5, 5, 1) )], [(5, 5, 1), (5, 6, 1)], [(5, 5, 1), (2, 5, 1)].

  Next, with reference to the content information management table 3g, content information existing in a range in which the distance from each extracted route is equal to or less than a specified value is extracted. For example, when the specified value is “0” and the content information management table 3g in FIG. 9 is referred to, the content information of serial numbers 1 to 5 is extracted.

  Next, the guidance information notification unit 3e sorts the content information of serial numbers 1 to 5 in consideration of the received line-of-sight direction. As an example, the content information in the right direction, the left direction, and the rear direction is arranged in order from the content information in the traveling direction. In this case, the content information is sorted in the order of serial number 2, serial number 1, serial number 4, serial number 5, serial number 3.

  Then, a character indicating the direction in which the ring ID mark 1 exists is added to each content information. “2” for the serial number 2 content information, “2” for the serial number 1 content information, “#” for the serial number 4 and 5 content information, and “3” for the serial number 3 content information. Give characters.

  The guidance information notification means 3e outputs a peripheral content information screen (for example, the peripheral content information screen shown in FIG. 7B) in which the peripheral content information is configured in HTML to the mobile terminal 2. On the peripheral content information screen of FIG. 7B, a title, a description, and a telephone number are presented as peripheral content information (for example, peripheral content information indicated by reference sign Cif). The title part is an anchor to the corresponding URL. Similarly, the telephone number portion is also an anchor for making a call. And the character (character shown by the code | symbol Csc) which shows a direction is shown to the head of each title.

  In the above-described example, the guidance information notification unit 3e configures the peripheral content information using only text. On the peripheral content information screen, the map information may be used to indicate the position and attribute of the content information on the map. In this case, the guidance information notification unit 3e changes the orientation of the map to be presented in consideration of the detected gaze direction. That is, the peripheral content information screen is configured by rotating the map so that the line-of-sight direction is at the top.

[Example 2]
A peripheral content information providing service provided as a web server in which the server device in the guidance system in the second embodiment is implemented as a web server and provided to a mobile terminal having a web browser will be described as an example. In the following description, as in the first embodiment, the ID is composed of four characters, and the user can recognize the four characters on the circular ID mark from the characters positioned above the circular ID mark when viewed from the user. It is assumed that the input is made in the order of the clock. In the following description, the description of the same reference numerals as those in FIGS. 1 and 4 is omitted.

  In the peripheral content information providing service, the server device 3 includes a destination designation unit 3a, a route direction determination unit, in addition to the ID input unit 3b, the position / direction detection unit 3c, the position / direction ID management table 3f, and the guidance information notification unit 3e. 3d.

  First, the user U accesses the URL of the server device 3 via the Web browser of the mobile terminal 2. At this time, the ID input unit 3b provides an ID input screen shown in FIG. 7A to the Web browser. The ID input screen includes a link L1 to the destination designation screen. When the user U selects this link L1, the destination designation screen provided by the destination designation means 3a (the destination designation screen in FIG. 10C). Screen) is presented to the Web browser.

  Next, when the user U selects a destination on the destination designation screen and presses the destination determination button P2, the selected destination is transmitted to the destination designation means 3a.

  Next, the destination designation means 3a holds a destination management table (for example, the destination management table 3h in FIG. 11) that associates the destination name with the location information of the destination (hereinafter referred to as destination location information). The destination name and destination position information are notified to the ID input means 3b and the route direction determination means 3d. The destination management table 3h has destination management data including a serial number field F31, a destination position information field F32, and a destination name field F33. The format of the destination position information field F32 (that is, the position information of the destination) may include the above-mentioned ID and position information of content information. Although not shown, the server device 3 includes destination management means for managing destination management data.

  In addition, a management table may be provided separately to hold different destinations for each user. Since each means provided in the server apparatus 3 is configured to provide one Web application in cooperation with each other, the destination for each user U may be held while intervening between the means. The designation of the destination is not necessarily performed on the destination designation screen, and it may be automatically set for each user by a person other than the user U or may be set by another application.

  After the destination is notified to the ID input means 3b and the route direction means 3d by any means (for example, the destination designation means 3a), the ID input screen shown in FIG. Is presented by the ID input means 3b. The ID input screen shown in FIG. 10A is a screen when “Exhibition Booth A” is selected as the destination, and the destination information is presented at the top.

  Next, when the user U stands at the position where the circular ID mark 1 is installed, the user U inputs the character string on the circular ID mark 1 according to the above-described order on the ID input screen, and selects the search button P1. To do. As a result, the input character string is passed as an ID to the position / direction detection means 3c of the server device 3 (for example, via the ID input means 3b).

  When the position / direction detection unit 3c receives an ID in the same procedure as in the first embodiment, the position / direction detection unit 3c refers to the position / direction ID management table 3f and detects the position and line-of-sight direction of the user U. Then, the ID, position information, and line-of-sight direction information are transmitted to the route direction determining means 3d.

  The route direction determination unit 3d determines the route direction to be followed by the user U using the position information transmitted from the position / direction detection unit 3c, the already-reported position information of the destination, and the route graph. This determination process can be performed using, for example, a general route search algorithm used in a car navigation system or the like. Information on the determined route direction is transmitted to the guidance information notification means 3e.

  Various procedures are conceivable for the route direction determining means 3d to determine the route direction. Here, the first route direction formulation procedure in which the route direction determination means 3d formulates the route direction will be described. In addition, when a plurality of circular ID marks arranged in the space to be guided are nodes, and there is a route that directly connects the positions of any two circular ID marks, the 2 It is assumed that a route graph provided with a path weighted by the distance between two annular ID marks is constructed in advance.

  Further, the route graph can be constructed by referring to information held in the position information field F13 and the route end point position information field F15 of the position / direction ID management table 3f shown in FIG. The route direction determining means 3d manages the constructed route graph as a two-dimensional array in the means in order to improve the speed of the graph processing.

  First, when receiving the ID from the position / direction detection unit 3c, the route direction determination unit 2d sets a node corresponding to the ID as a current location node on the route graph.

  Next, the ID of the circular ID mark existing at the position closest to the destination is specified by referring to the position information of the destination (that is, the destination position information) and the position / direction ID management table.

  Next, a node corresponding to the circular ID mark of the ID is set as a destination node.

  Next, in the route graph, the shortest route connecting the current location node and the destination node is searched.

  Next, the path selected as the shortest path among the paths connected to the current location node is specified. The position / direction ID management table 3f is referred to using the position information of the start point of the route corresponding to the path and the position information of the end point of the route as keys, and one of the IDs of the circular ID mark corresponding to the current node is selected. Furthermore, based on the direction information corresponding to the ID, it is possible to specify in which direction the route is viewed from the position (current location) of the annular ID mark. This direction is determined as the route direction that the user U should travel.

  In addition to the first route direction formulation procedure described above, the route direction can also be formulated by the following second route direction formulation procedure.

  First, for each destination, the guidance system is provided with a destination direction management table in which current position information is associated with an ID indicating a route direction. FIG. 12 shows an example of the destination direction management table 3i. The destination direction management table 3i includes a serial number field F41, a current position information field F42 for storing current position information, an ID (path direction ID) field F43 indicating a route direction toward the corresponding destination, and next position information. Destination direction management data including a next position information field F44 for managing the destination position.

  Next, when the ID is received from the position / direction detection means 3c, the position / direction ID management table 3f shown in FIG. 8 is referred to and the position information corresponding to the ID is confirmed.

  Next, using the position information as current position information, the destination direction management table 3i corresponding to the destination set in advance is referred to, and an ID indicating the route direction corresponding to the current position information is selected.

  Next, the direction information corresponding to the ID is acquired again from the position / direction ID management table 3f shown in FIG. 8, and the direction indicated by the direction information is determined as the route direction to be followed by the user U.

  Each time the ID information is received from the position / direction detection means 3c until the next position information shown in the destination direction management table 3i matches the position information of the designated destination, the above procedure is repeated to repeat the above procedure. To get directions.

  Note that the route direction determination unit 2d may include first and second route direction formulation units that implement the first and second route direction formulation procedures, respectively.

  Finally, the route direction determination unit 2d transmits at least the selected ID to the guidance information notification unit 3e.

  When the ID is received as the information on the route direction determined by the route direction determining unit 3d, the guidance information notifying unit 3e includes the first character of the ID (for example, the character indicated by the symbol CS). (For example, the screen shown in FIG. 10B) is configured and presented on the web browser of the mobile terminal 2. The character corresponds to a character that is on the circular ID mark 1 corresponding to the current location node and indicates the direction of the route.

  In the second embodiment, the server device 3 further includes a content information management table 3g, and can perform a peripheral content information providing service. When this service is implemented, the guidance information notification means 3e further configures the peripheral content information in the same procedure as in the first embodiment using the ID received as the route direction information as a key, and uses this information as the route direction information. The added screen (for example, the screen shown in FIG. 10D) is configured and provided to the Web browser of the mobile terminal.

  In particular, when the route direction to be followed by the user U is determined, the guidance information notification unit can configure the peripheral content information in consideration of the route direction. That is, as shown in FIG. 10D, when the character indicating the route direction (character indicated by the code CS) is “2”, the peripheral content arranged in order from the content information associated with the position in the direction “2” Can compose information.

[Example 3]
The third embodiment improves a problem caused by a mistake that a user erroneously inputs a character included in an ID as a similar character.

  An example of the annular ID mark according to the third embodiment will be described with reference to FIGS. The annular ID mark 21A in FIG. 13 and the annular ID mark 21B in FIG. 14 are presumed to be used by a mobile phone, and can be input with a numeric keypad (dial key) of the mobile phone. “,” “2,” “3,” “4,” “5,” “6,” “7,” and “8” are used to construct the ID.

  Note that “9” is also a character that can be entered with the numeric keypad, but “6” and “9” are similar figures by rotation conversion (for example, 180-degree rotation conversion), so that the user who viewed the annular ID mark There are many mistakes in entering “6” and “9” by mistake. In order not to cause a problem even if such an input mistake occurs, a character set that is used for the ID configuration is obtained by removing “9” from characters that can be input with the numeric keypad. Information on the character set (for example, character code information and shape information) is managed by a storage unit that stores and manages information in a predetermined area of a storage unit provided in advance in the server device 3.

  In the circular ID mark 21A in FIG. 13, a character corresponding to a direction that needs to be instructed to the user and a character corresponding to a direction that does not need to be instructed to the user are adopted. For example, characters indicating a direction toward an object (for example, a wall) that does not need to be indicated are “0” (for example, reference numerals 21Ac and 21Ad in FIG. 13). Further, the characters indicating the direction toward the instruction target (for example, the route direction) are “1” (reference numeral 21Aa in FIG. 13) and “2” (reference numeral 21Ab in FIG. 13). That is, each character constituting the ID in the annular ID mark 21A in FIG. 13 may not be different.

  Furthermore, when the position / direction detection means 3c of the server device 3 receives an ID including “9”, it converts the position / direction ID management table 3f ′ in FIG. 16 after converting “9” to “6”. Referring to, the position direction corresponding to the ID is detected. Note that the position / direction ID management table 3f 'in FIG. 16 has the same data configuration as the position / direction ID management table 3f in FIG. 8, but two-dimensional coordinates are employed in the fields F13, F14, and F15.

  Note that not only numbers and characters but also IDs (for example, IDs in the circular ID mark 21C in FIG. 15) are configured using symbols (symbols) such as “Δ” and “□”. A set of characters used to construct a character is subjected to rotation conversion (for example, 180-degree rotation conversion) so that characters that have the same shape or similar to other characters are not included. . That is, the set of characters is formed of a set of characters whose shapes are not similar to each other by rotational transformation.

  In addition, the position / direction detection unit 3c of the server device 3 includes a character that does not exist in the set of characters used to construct the ID in the received character string, and performs rotation conversion on the shape of the character. If a character whose shape matches or is similar to that of the character is included in the set, the character included in the received ID is changed to a character included in the set that is similar to (assigned to) the character that has been rotated. ID generated. Then, the position / direction corresponding to the generated ID is detected with reference to the position / direction ID management table 3f ′ in FIG.

  The server device 3 according to the third embodiment can be realized using, for example, a Web server connected to the Internet. In this case, each means of the server device can be implemented using a Web application development system such as an HTML (HyperText Markup Language) and each script language (PHP (Hypertext Preprocessor), Perl, Ruby, Servlet) program. Further, the guidance service provided by the server device 3 can be used by a mobile terminal having a Web browser.

  In the following description, the server device 3 according to the third embodiment is implemented as a Web server, and an example in which a peripheral content information providing service for a mobile terminal having a Web browser is realized will be described. In the following explanation, an ID is composed of four characters, and the user inputs the four characters on the circular ID mark in order from the character positioned above the circular ID mark in the clockwise direction. It is supposed to let you. Also, on the premise of use by a mobile phone (that is, a mobile terminal), a set {“0”, “1”, “2”, “3”, “4”, “5”, “6”, “7”, “8”} are used to construct an ID.

  An outline of the operation of the server device according to the third embodiment will be described with reference to FIG. In the guidance system realized by the server device, a plurality of annular ID marks such as the annular ID mark 21A in FIG. 13 are arranged in the space to be guided.

  First, the user accesses the server device 3 through a Web browser of the mobile terminal 2 using a URL (Uniform Resource Locator) of the server device 3. Next, the ID input means 3b provides the ID input screen shown in FIG. 17A to the Web browser (that is, the input / output means 2a in FIG. 1). The user inputs characters on the circular ID mark to the portable terminal 2 in a predetermined order based on the user's viewpoint at each point where the circular ID mark is arranged.

  When the user comes to the position where the circular ID mark is arranged, the character string on the circular ID mark (for example, “2100”) is displayed in the clockwise direction (arrow α direction) from the line-of-sight direction to the ID input screen. ) And the search button P1 is selected. As a result, the input character string is transmitted as an ID to the position / direction detection means 3c of the server device 3.

  In order to encourage such an input operation to be performed accurately, the ID input screen presented by the ID input means 3b of the server device 3 to the mobile phone 2 when the guidance system in the third embodiment is used is displayed on the system. Presents information for instructing the user on the expected input order. FIG. 17 shows an ID input screen (for example, an input screen as shown in FIG. 17A) instructing to input characters in the clockwise direction (in the direction of the arrow α) from the character above the circular ID mark as viewed from the user. Indicates.

  Thereafter, the mobile terminal 2 transmits the input character string as an ID to the server device 3 via a predetermined communication line (for example, a mobile phone network or the Internet), and the server device 3 performs processing based on the ID. The mobile terminal 2 is provided with a guidance service (for example, a peripheral content information screen display service as shown in FIG. 17B).

  When receiving the ID, the position / direction detection means 3c refers to the position / direction ID management table 3f ', detects the user's position information and line-of-sight direction information, and sends it to the guidance information notification means 3e. For example, when “2100” is received as the ID, the position / direction detection means 3c refers to the position / direction ID management table 3f ′ in FIG. 16, “2100” indicates the position of (7, 5), and a vector ( Confirm that the direction of (1, 0) is the line-of-sight direction. Then, the position information and the line-of-sight direction information corresponding to the ID are transmitted to the guidance information notification means 3e.

  Here, when an ID including “9” is received, the position / direction detection unit 3c converts “9” into “6” and then refers to the position / direction ID management table 3f ′. A position direction corresponding to the ID is detected. For example, when an ID of “2900” is received, “9” is converted to “6”, updated to an ID of “2600”, and then the position information ( 15, 10) and direction information (0, -1) are detected.

  In the third embodiment, the content information management table uses a content information management table 3g ′ having the same fields as the content information management table 3g in FIG. The content information management table 3g ′ is also a table for managing content information linked to position information. A data configuration example of the content information management table 3g ′ will be described with reference to FIG. The content information management table 3g ′ in FIG. 18 includes content including a serial number field F21, a position information field F22, a URL field F23, a title field F24, an explanation field F25, and a telephone number field F26, as in FIG. It has information management data. Each field has the same format as that in FIG. 9, but only the position information field F22 has two-dimensional position coordinates.

  Upon receiving the user position information and line-of-sight direction information from the position / direction detection unit 3c, the guidance information notification unit 3e refers to the position / direction ID management table 3f ′ and the content information management table 3g ′ to configure the peripheral content information. . An example of the procedure for configuring the peripheral content information is shown below.

  (Step 1) First, when the guidance information providing means 3e receives the ID “2100”, the user position information (7, 5), and the direction information (−1, 0) from the position / direction detection means 3c, the position / direction ID With reference to the management table 3g ′, the existing route is extracted starting from the position information (7, 5) indicated by the ID “2100”. That is, two routes [(7, 5), (7, 0)] and [(7, 5), (0, 5)] starting from the position information (7, 5) are extracted.

  (Step 2) Next, with reference to the content information management table 3g ', content information management data existing in a range in which the distance from each extracted route is equal to or less than a specified value is extracted. For example, when the specified value is 0 and the content information management table 3g ′ in FIG. 18 is referred to, the content information management data of serial numbers 1 to 5 are extracted.

  (Step 3) Next, the guidance information notification means 3e sorts the content information of serial numbers 1 to 5 in consideration of the received gaze direction information. As an example, the content information management data in the right, rear, and left directions are arranged in order from the content information management data in the line-of-sight direction (front). In this case, the content information management data is sorted in the order of serial number 1, serial number 2, serial number 3, serial number 4, serial number 5.

  (Step 4) Information indicating the direction of existence (front, back, right, left) and characters indicating the direction of presence on the circular ID mark are assigned to each content information management data. Characters “2” are assigned to the content information management data of serial numbers 1, 2, and 3 and characters “1” are assigned to the content information management data of serial numbers 4, 5 (corresponding to each other). And each content information management data to which the character was given is constituted into HTML data, for example, and is displayed with respect to portable terminal 2 like Drawing 17B.

  The guidance information notifying means 3e outputs a peripheral content information screen (FIG. 17B) in which the above peripheral content information is configured in HTML to the mobile terminal 2. In the peripheral content information screen of FIG. 17B, a title, a description, and a telephone number are presented as the content information Cif. The title part is an anchor to the corresponding URL. Similarly, the telephone number portion is also an anchor for making a call. Information Csc (for example, front, back, right, left) indicating the direction and characters on the circular ID mark are presented at the head of each title.
