  However, many of the conventional systems including the above-described prior art documents perform guidance while displaying in real time on the map all the routes from the departure point to the destination and a mark indicating the current location on the map. For this reason, it is necessary for the user to check on the screen whether or not he / she has deviated from the route, etc., and induces harmful effects (inconvenience to the surroundings, accidents, injuries, etc.) of walking while watching the screen. It was also a cause.

  By the way, when aiming for a destination, it is often moved relying on various guide points (intersections, stations, convenience stores,...) That serve as landmarks along the way. That is, it is considered that the function of the route guidance is sufficiently functioned only by displaying the information of each guidance point existing on the route to the destination on the screen. In addition, since the information displayed is only information on each guide point, the user does not need to check the screen one by one, and harmful effects caused by watching the screen as described above (disturbance to the surroundings, accidents, injuries, etc.) Is also suppressed. However, simply displaying the information of each guide point on the route makes it difficult to grasp the relationship between the current location and each guide point, so various ways of displaying the guide are required to realize easy-to-understand route guidance. Necessary.

  2-4 is a figure which shows the example of the content of the various map data stored in the memory | storage part 12 of the information terminal 1. FIG. The map data includes guide point information 40, destination information 50, and a route database 60.

  FIG. 2A is a diagram schematically showing a guide point. The guidance point is provided at an arbitrary position in a space for which route guidance is performed (hereinafter also referred to as “guidance space S”). The guide space S may be a two-dimensional space or a three-dimensional space. The guide space S may be an indoor space or an outdoor space. Or the space which includes both indoor space and outdoor space seamlessly may be sufficient.

  The guidance point is provided at a place where route guidance is required, such as a branch point of a route such as a crossroad or a T-junction, or a point where a hierarchy such as an escalator or elevator changes. If it is guidance inside the station, it is provided at the entrance to the station, the ticket gate of the station, the stairs and escalator to the station platform, etc. Airport information is provided at check-in counters, security gates, boarding gates, etc. In the case of road guidance, it is provided at intersections, entrance / exit of expressways, etc.

FIG. 2B is a diagram showing an example of the data content of the guide point information 40 that holds information on the guide points. In the figure, the guide point ID 41 is an identification number for uniquely identifying the guide point. The position information 42 is information for detecting the location of each guide point in the guide space S. For example, information on latitude and longitude of each guide point. Moreover, the information (beacon ID, installation location, etc.) of the beacon (for example, BLE beacon) uniquely linked | related with each guidance point installed near each guidance point may be sufficient. In this case, the information terminal 1 detects the location of each guide point associated with each beacon by receiving a beacon signal transmitted from the beacon. Moreover, the information (access point ID, installation location, etc.) of a Wi-Fi access point uniquely associated with each guide point installed near each guide point may be used. In this case, the information terminal 1 receives the signal transmitted from the Wi-Fi access point, and detects the location of each guide point associated with each Wi-Fi access point. Moreover, information (transmitter ID, installation location, etc.) of an ultrasonic transmitter that emits an ultrasonic signal uniquely associated with each guide point installed near each guide point may be used. In this case, the information terminal 1 detects the location of each guide point associated with each ultrasonic transmitter by receiving the ultrasonic signal emitted from the ultrasonic transmitter.
The guidance display information 43 is guidance information (text information) of guidance points displayed on the display unit 14 (display screen) of the information terminal 1. The type 44 indicates a category of guide points such as intersections, stairs, convenience stores, ticket gates, and station platforms.

  FIG. 3 is a diagram illustrating an example of data contents of the destination information 50. The destination information 50 holds destination information. In the figure, the destination ID 51 is identification information for uniquely identifying the destination. The position information 52 is information for detecting the location of each destination in the guidance space S. Similar to the guide point, for example, information on latitude / longitude of each destination and information on beacons installed near each destination (beacon ID, installation location, etc.). The destination name 53 is the name of the destination. The type 54 indicates a destination category such as a museum, a movie theater, a cafe, and so on.

  FIG. 4 is a diagram illustrating an example of data contents of the route database 60. The route database 60 stores each route for reaching each destination. One route holds the destination and each guide point for reaching the destination in the order of the route. For example, “Route 1” in the figure holds a destination G1, a guidance point N1, a guidance point N2, and a guidance point N3 for reaching the destination G1. Since the guide points are held in the order of the route, the user can reach the destination G1 by following the route in the order of the guide point N1, the guide point N2, and the guide point N3.

  Next, the operation of the information terminal 1 (guidance information display device) will be described with reference to the flowchart of FIG.

  First, the control unit 11 of the information terminal 1 accepts input of information on a departure place (current location) and a destination (step S1). “Input” includes inputting manually by a user operation via the input unit 13 and automatically inputting regardless of the user operation.

  In the present embodiment, the destination is manually input by user operation via the input unit 13. On the other hand, the departure point is automatically input when the control unit 11 acquires the position information of the information terminal 1. The means for acquiring position information is not particularly limited. For example, when the guidance space S is outdoors, the position information of the information terminal 1 is acquired by GPS (Global Positioning System). When the guidance space S is indoors, the position information of the information terminal 1 in the guidance space S is acquired by beacons that are exhaustively arranged (for example, every several tens of meters) in the guidance space S. . The position acquisition method using a beacon may be a proximity method (the position linked to the ID of the nearest various beacons is the current position), or a three-point positioning method (estimates the distance from various beacons whose positions are obvious from the radio wave intensity). In addition, the current position may be estimated by performing three-point positioning). In addition, position information may be acquired by pedestrian dead reckoning (PDR) using the sensors (acceleration sensor, gyro sensor, etc.) of the information terminal 1 (the initial position of the PDR uses GPS or a beacon. To get).

  Subsequently, the control unit 11 of the information terminal 1 refers to the route database 60 and constructs one route that passes through at least one guide point from the departure point to the destination input in step S1 (step S1). S2).

Specifically, the control unit 11 extracts a route that matches the destination input in step S1 from the route database 60, and obtains route data 70 including information on guide points from the departure point (current location) to the destination. Generate.
For example, it is assumed that “G1” is input as the departure point (current location) and “G1” is input as the destination. At this time, the control unit 11 extracts “Route 1” having the same destination from the route database 60, and each guidance point (N1) from the guidance point N1 closest to the departure point to the destination is extracted from the extracted route 1. , N2, N3) is generated.
In addition, for example, it is assumed that “G2” is input as the departure point and “G2” is input as the destination. At this time, the control unit 11 extracts “Route 2” having the same destination from the route database 60, and each guidance point (N5) from the guidance point N5 closest to the departure point to the destination is extracted from the extracted route 2. , N7) is generated.

  When there are a plurality of routes that reach the destination, a route with a small number of guide points is selected. For example, suppose that “Guide point N4” is input as the departure point (current location) and “G2” is input as the destination. At this time, the route database 60 of FIG. 4 has two candidates “route 2” and “route 3” as routes to the destination G2. Here, “Route 2” has “3” as the number of guide points, and “Route 3” has “2” as the number of guide points. Therefore, the control unit 11 selects “Route 3” with a small number of guide points. To do.

  FIG. 7 is a diagram illustrating an example of the data content of the generated route data 70. The figure shows an example of route data 70 in the case where “Guide point N1” is input as the departure point (current location) and “G1” is input as the destination. As shown in the figure, the route data 70 includes information on each guide point (N1, N2, N3) for reaching the destination “G1” from the departure point (current location).

  The route construction method is not limited to the example of this embodiment. For example, a route from the departure point to the destination may be constructed using link information (not shown) that holds the connection relationship of each guide point. The link information includes identification information for uniquely identifying each link, a guide point that is the start point of the link, a guide point that is the end point of the link, a link cost such as a moving distance and required time of each link, and the like. The information terminal 1 refers to the link information, calculates the total value of the link cost for various routes passing through the guide point from the departure point to the destination by an algorithm such as the Dijkstra method, and the total value of the link cost is the smallest The route that becomes (shortest route) is constructed.

  Subsequently, the control unit 11 of the information terminal 1 displays a list of information on each guide point included in the route data 70 generated in step S2 on the display unit 14 (display screen) in order of the route (step S3).

And the control part 11 of the information terminal 1 performs the highlight display process which highlights the information of the next guidance point of a route order (step S4).
Here, the highlighting process will be described with reference to the flowchart of FIG. By the highlighting process, the information on the next guide point that the user aims at is displayed on the display screen in such a manner that it is visually noticeable. As a result, the user can easily and instantly grasp the highly important guidance information, so that the user can be suitably guided to the destination. In addition, display control is performed in accordance with the importance of other guide points other than the next guide point.

  First, the control unit 11 of the information terminal 1 displays the size of the display area of the next guide point in the route order in view of the current location (“Departure” when this processing is first executed), and displays at least other guide points. It is displayed larger than the size of the area (step S11). As a result, the information on the next guide point to be aimed at is displayed with the highest emphasis, so that the user can easily and instantly grasp the next point to be aimed at from the current location.

  Further, the control unit 11 displays the size of the display area of the guide point far away from the destination (the guide point existing from the departure point to the next guide point) with the next guide point as a reference (Step S12). ). As a result, the information on the guide points with low importance that have already passed is displayed small on the screen.

  In addition, the control unit 11 displays the display area at a predetermined guide point with a larger size. The “predetermined guide point” is an arbitrary guide point on the route to be individually highlighted other than the next guide point. In this embodiment, the “predetermined guide point” is set as a guide point close to the destination with respect to the next guide point (a guide point existing from the next guide point to the destination), and the guide point is displayed. The size of the area is sequentially increased in the order of the root (intensified in the order of the root) and displayed (step S13). At this time, the size of the display area of the guide point closest to the destination is set to a size equal to or not exceeding the size of the display area of the next guide point. Thereby, it is possible to display the information of the guide point close to the destination with emphasis as it is closer to the destination.

The way of displaying each of the above guide points is mainly based on the following main points.
(1) Information with the highest importance for the user is information on the next guide point as viewed from the current location. (2) Information with the next highest importance for the user is information on the guide point closer to the destination. (3) Information that is less important to the user is information on guidance points that have already passed. (1) is mainly due to step S11, (2) is mainly due to step S13, and (3) is mainly related to This is realized by step S12.

Returning to the flowchart of FIG.
Subsequently, the control unit 11 of the information terminal 1 updates and acquires the current location (step S5),
It is determined whether or not the current location has reached the destination (step S6). If the destination has not been reached (step S6; No), the control unit 11 determines whether or not the current location has reached one of the guide points (step S7). For example, if the distance between the acquired current location and the guide point is within a predetermined distance, it is determined that the guide point has been reached.
Alternatively, when a signal emitted from a beacon, Wi-Fi access point, ultrasonic transmitter, or the like installed near the guidance point is detected, it may be determined that the guidance point has been reached. If it is determined that the guide point has not been reached (step S7; No), the process returns to step S5 and continues to acquire and update the current location.

On the other hand, if it is determined that one of the guide points has been reached (step S7; Yes), the process returns to step S4, and the control unit 11 executes the above-described highlighting process (see FIG. 6) again (step S4). . That is, every time the user (information terminal 1) reaches the guidance point, the highlighting process is executed, and information on the next guidance point after the reached guidance point is highlighted.
Then, the control unit 11 continues to acquire and update the current location. When the current location reaches the destination (step S6; Yes), a message such as “Arrived at the destination” is displayed on the display unit 14 (display screen). Display and finish the process.

FIG. 8 is a diagram illustrating an example of highlighting. FIG. 8 is an example of a display screen for guiding a route 1 (guidance point N1 → guidance point N2 → guidance point N3) to the destination G1 based on the route data 70 of FIG.
FIG. 8A is an example of a display screen from the departure point to the arrival at the guide point N1 (when the next guide point is N1). As shown in the figure, the size of the display area A1 of the guidance display information (“00”) at the next guidance point N1 is made larger than the sizes of the display areas A2 and A3 at least at other guidance points N2 and N3. indicate.
Further, the display area size of the guide points N2 and N3 close to the destination is sequentially enlarged in the order of the route (N2 → N3) with the next guide point N1 as a reference and displayed. However, the size of the display area A3 of the guide point N3 closest to the destination is equal to or not exceeding the size of the display area A1 of the next guide point N1. That is, the display area is controlled so as to maintain the relationship of “size of display area A1 ≧ size of display area A3> size of display area A2”.

FIG. 8B is an example of a display screen from the arrival at the guidance point N1 to the arrival at the guidance point N2 (when the next guidance point is N2). As shown in the figure, the size of the display area A2 of the guidance display information (“ΔΔΔ”) of the next guidance point N2 is made larger than the sizes of the display areas A1 and A3 of at least the other guidance points N1 and N3. indicate.
Further, the display area A1 of the guidance point N1 far from the destination (already passed) is reduced in size with the next guidance point N2 as a reference and displayed.

FIG. 8C shows an example of a display screen from the arrival at the guidance point N2 to the arrival at the guidance point N3 (when the next guidance point is N3). As shown in the figure, the size of the display area A3 of the guidance display information ("xxx") at the next guidance point N3 is made larger than the sizes of the display areas A1 and A2 at least at the other guidance points N1 and N2. indicate.
In addition, the display areas A1 and A2 of the guide points N1 and N2 far from the destination (already passed) from the next guide point N3 are displayed in a uniformly reduced size.

  Note that the highlighting method is not limited to controlling the size of the display area of each guide point. Any method may be used as long as the information on the next guide point is visually impressed more strongly than the information on other guide points. For example, as shown in FIG. 9, highlighting may be performed by changing the background color of the display area of the next guidance point. Further, highlighting may be performed by increasing the font size of the display information of the next guide point or changing the font type or font color.

  The first embodiment has been described above. According to the first embodiment, information on each guide point to the destination is displayed as a list. Unlike the conventional system, the entire route from the starting point to the destination and the mark indicating the current location on the map are not displayed on the map in real time. There are few updates. Therefore, the number of times the user can visually recognize the screen can be reduced, and adverse effects (inconvenience to the surroundings, accidents, injuries, etc.) caused by walking while watching the screen can be prevented. In addition, when displaying the information of each guide point as a list, the information on the next guide point in the route order as viewed from the current location is highlighted and displayed, so that the user can easily and instantly grasp the next point to be aimed at. Further, other guidance points are also highlighted according to their importance.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, processing when the user deviates from the route is added to the processing of the first embodiment (see FIG. 5).

  FIG. 10 is a flowchart showing a process for giving a warning when the user deviates from the route. Steps S21 to S26 and S29 are the same as those in the first embodiment. That is, the departure point (current location) and the destination are input (step S21), a route from the departure point to the destination is constructed (step S22), and information on the guide points on the route is displayed in a list in the order of the route (step S22). S23) A highlighting process is executed according to the departure place (current location) (step S24). Subsequently, while updating the current location, it is determined whether or not the destination has been reached (step S26), and the highlighting process is executed when any of the guide points is reached (step S29; Yes) (step S24). ) Repeatedly.

  In the second embodiment, while updating the current location, it is further determined whether or not the vehicle has deviated from the route (step S27). The determination that the vehicle has deviated from the route is performed by, for example, the following methods (methods A and B).

(Method A) It is determined whether or not the shortest distance Dmin between the current location and the straight route is within a threshold value, and if it exceeds the threshold value, it is determined that the vehicle has deviated from the route. The straight line route is a line connecting the respective guide points in a straight line in the route order, and the shortest distance Dmin to the straight line route is the shortest length among the lengths of perpendicular lines from the position coordinates of the current location to each straight line. Say it. For example, in a certain route (guidance point 1 → guidance point 2 → guidance point 3 → guidance point 4), the length of a perpendicular line from the current location to the straight line connecting the guidance location 1 and the guidance location 2 is L1, and from the current location to the guidance location 2 The length of the perpendicular to the straight line connecting the guide points 3 is L2, and the length of the perpendicular from the current location to the straight line connecting the guide points 3 and 4 is L3. In this case, the shortest distance Dmin to the straight line route is Dmin = min (L1, L2, L3). When Dmin exceeds a predetermined threshold value, it is determined that the vehicle has deviated from the route.

(Method B) A route deviation area (not shown) is set for each route in the route database 60, and when entering the route deviation area is detected, it is determined that the route has deviated. The route departure area is defined by an arbitrary position specifying means. For example, the route departure area is defined by the latitude / longitude range, and when the current location (latitude / longitude) acquired by the GPS sensor of the information terminal 1 enters the route departure area range, it is determined that the route has deviated. . Alternatively, when the information terminal 1 detects an NG beacon existing in the route departure area using a beacon existing in the route departure area (referred to as “NG beacon”), it may be determined that the route has deviated.

  If it is determined that the route has been deviated (step S27; Yes), the control unit 11 issues a warning that the route has been deviated (step S28). The warning method is, for example, (1) changing the background color of the display area of the next guidance point, (2) changing the background color of the display area of the next guidance point, and flashing the display area. (3) warning from the speaker Sound is generated (4) Vibration is generated by the vibration sensor (5) LED is blinked.

FIG. 11 is a flowchart showing a process for reconstructing a route when the user deviates from the route. Steps S31 to S37 are the same as steps S21 to S27 in FIG.
In FIG. 11, when it is determined that the route has been deviated (step S37; Yes), the control unit 11 reconstructs the route from the current location (position when it is determined that the route has been deviated) to the destination (step S38). ). The process for reconstructing the route is the same as the process for constructing the route in step S2 of the first embodiment.

  When the route is reconstructed, information on the guide points on the reconstructed route is displayed in a list (step S33), and highlighting processing is executed based on the information on the guide points on the reconstructed route (step S33). S34).

  The second embodiment has been described above. The second embodiment is obtained by adding processing in the case of deviating from the route to the first embodiment, and an example of processing for giving a warning when deviating from the route and an example of processing for performing reroute when deviating from the route. And explained. By the former process, the user can immediately recognize that the route is wrong. Further, since the latter process automatically rebuilds the route even if the user makes a mistake in the route, guidance to the destination can be continued according to the reconstructed route.

FIG. 16 is a flowchart showing the operation of the fourth embodiment. Step S61
Steps up to step S67 are the same as steps S21 to S27 in FIG.

In the fourth embodiment (FIG. 16), when it is determined that the route has been deviated (step S67; Yes), a warning that the route has been deviated is issued and the fact that the route has deviated is notified to the cooperation terminal 2. (Step S68, Step S69).
When the control unit 21 of the cooperation terminal 2 receives a notification that the route has deviated from the information terminal 1 (step S71), the control unit 21 issues a warning that the route has deviated (step S72).

  The fourth embodiment has been described above. According to the fourth embodiment, a warning when the route deviates between the information terminal 1 and the cooperation terminal 2 is linked. Thereby, for example, even when the information terminal 1 cannot be browsed with a bag or the like, since the warning is notified in the cooperation terminal 2, it is possible to reliably grasp that the route has been deviated.

[Fifth Embodiment]
Next, a fifth embodiment of the present invention will be described with reference to FIGS.
FIG. 17 is a diagram showing an outline of a guidance information display system 200 according to the fifth embodiment. The guidance information display system 200 is configured by connecting one or more information terminals 1 and a server 3 via a network 4. The fifth embodiment is characterized in that the server 3 performs route construction. The network 4 includes a LAN (Local Area Network), a WAN (Wide Area Network) connected to a wider area, or a public communication line such as the Internet, a base station, and the like. The communication connection in the network 4 may be wired or wireless.

  FIG. 18 is a diagram illustrating an example of the hardware configuration of the server 3. As shown in the figure, in the server 3, a control unit 31, a storage unit 32, an input unit 33, a display unit 34, a communication I / F unit 35, and a peripheral device I / F unit 36 are connected via a bus 39. Since each part is substantially the same as the hardware configuration of the information terminal 1 (FIG. 1), description thereof is omitted.

  The storage unit 32 of the server 3 stores at least a route database 60 (FIG. 4) that is referred to when a route is constructed. If necessary, guidance point information 40 (FIG. 2) and destination information 50 are stored. (FIG. 3) may be stored.

The operation of the guidance information display system 200 will be described with reference to the flowchart of FIG.
First, the control unit 11 of the information terminal 1 accepts the input of the departure point and destination information (step S81), and the identification information for uniquely identifying the information terminal 1 and the inputted departure point and destination information are stored in the server. 3 (step S82).

  The control unit 31 of the server 3 receives the information of the departure point and the destination together with the identification information of the information terminal 1 from the information terminal 1, and stores them in the storage unit 32 (step S83).

  Subsequently, the control unit 31 of the server 3 refers to the route database 60, constructs one route that passes through at least one guide point from the departure place to the destination received in step S83, and reaches the destination. Route data 70 holding information on the guide points is generated (step S84).

  And the control part 31 of the server 3 transmits the route data 70 produced | generated in step S84 to the information terminal 1 (step S85).

  Subsequently, the control unit 11 of the information terminal 1 receives the route data 70 from the server 3 (step S86), and displays a list of information on each guide point included in the route data 70 on the display unit 14 (display screen) in order of the route. (Step S87).

  And the control part 11 of the information terminal 1 performs the highlight display process which highlights the information of the next guidance point of the route order (step S88). The content of the highlighting process is the same as in FIG.

  Subsequently, the control unit 11 of the information terminal 1 updates and acquires the current location (step S89), and determines whether or not the current location has reached the destination (step S90). If the destination has not been reached (step S90; No), the control unit 11 determines whether or not the current location has reached one of the guide points (step S91). If it is determined that the guide point has not been reached (step S91; No), the process returns to step S89 and continues to acquire and update the current location.

On the other hand, if it is determined that one of the guide points has been reached (step S91; Yes), the process returns to step S88, and the control unit 11 executes the highlighting process (see FIG. 6). That is, every time the user (information terminal 1) reaches the guidance point, the highlighting process is executed, and information on the next guidance point after the reached guidance point is highlighted.
Then, the control unit 11 continues to acquire and update the current location, and when the current location reaches the destination (step S90; Yes), a message such as “Arrived at the destination” is displayed on the display unit 14 (display screen). Display and finish the process.

  The fifth embodiment has been described above. According to the fifth embodiment, since the server 3 is provided, the server 3 can be burdened with a part of the processing of the information terminal 1, so that the calculation load on the information terminal 1 can be reduced.

  In the fifth embodiment, the same processing as in the first embodiment is realized by the guidance information display system 100200 including the server 3, but the same processing as in the second to fourth embodiments. May be realized by the guidance information display system 100200. In either case, the server 3 performs route construction.

<Example: Exit guidance>
Next, an embodiment to which the present invention is applied will be described with reference to FIGS. In particular, “exit guidance” that guides the route to the station exit closest to the destination set by the user will be described as an example.

  20 to 22 show the contents of various types of map data stored in the storage unit 12 of the information terminal 1. The map data includes guide point information 40a, destination information 50a, and a route database 60a.

  FIG. 20 is a diagram illustrating an example of data content of the guide point information 40a. The guide point information 40a holds information on each guide point in the station premises. The guide point ID 41a is identification information for uniquely identifying the guide point. The position information 42a is information for detecting the location of the guide point. In this embodiment, since the guidance point is provided in a station with a poor GPS radio wave reception environment, the location of the guidance point is detected by a beacon. The guidance display information 43a is display information related to the guidance point displayed on the display unit 14 (display screen) of the information terminal 1. The type 44a is a category of guide points such as “station platform”, “ticket gate”, “exit”, “stairs”, “escalator”, and “elevator”.

  FIG. 21 is a diagram illustrating an example of data contents of the destination information 50a. Although the destination information 50a mainly holds information on destinations outside the station, facilities (toilet, shop, etc.) in the station school may be held as destinations. The destination ID 51a is identification information for uniquely identifying the destination. The destination name 52a is a name of the destination. The type 53a is a destination category.

  FIG. 22 is a diagram illustrating an example of data contents of the route database 60a. The route database 60a holds each guide point (guide point 1 “station (home)”, guide point 2 “ticket gate”, guide point 3 “exit”) up to the exit of the station closest to the destination.

  For example, if the destination is “Jingumae Elementary School”, the guidance point on the route to the exit of the station closest to “Jingumae Elementary School” is “Omotesando” (station (home)) ), Guide point 2 (second guide point) is “Omotesando intersection ticket gate” (ticket gate), and guide point 3 (third guide point) is “A2” (exit).

  Also, if the destination is “Minami Aoyama 5 chome”, the guide point on the route to the exit of the station closest to “Minami Aoyama 5 chome” is “Omotesando” (station ( Home)), guide point 2 (second guide point) becomes "Aoyama Gakuin direction ticket gate" (ticket gate), and guide point 3 (third guide point) becomes "A5B1" (exit).

  In this embodiment, for the sake of simplicity, there are three types of guide points (categories): “station (home)”, “ticket gate”, and “exit”, but the types and number of guide points are limited to these. Not.

  In the example of FIG. 22, the exit of the station is specified by the exit number, but depending on the station, the direction of “North Exit”, “South Exit”, etc., or the place name of the destination after exit such as “Yaesu Exit” “Marunouchi Exit” It may be specified by.

  An “NG beacon” is set for each route in the route database 60a. The NG beacon is a beacon installed in an area deviating from the corresponding route among the installed beacons.

  FIG. 23 is a diagram illustrating an example of a screen for setting a destination in exit guidance. When the user presses the list button 141 in FIG. 23A, a station list (not shown) is displayed. When a predetermined station is selected from this list, information on the selected station is displayed as shown in FIG. The figure shows a screen example when the user selects “Omotesando”. Subsequently, when the user presses a button 142 (“search for an exit from the destination”), the screen transitions to a screen shown in FIG. 23B, and a destination list 144 around “Omotesando” is displayed. The user sets a destination by selecting a desired destination from the destination list 144. The departure point is set by acquiring the current location of the user by an arbitrary position acquisition unit. For example, if the current location of the user is outdoor, it is acquired by GPS, and if it is indoor, it is acquired by BLE beacon.

  When the departure point and the destination are set, the information terminal 1 refers to the route database 60a and constructs a route to the station exit near the destination. Here, it is assumed that the user selects “Nezu Art Museum” as the destination. In this case, the information terminal 1 extracts “route n” whose destination is “Nezu Art Museum” from the route database 60a (FIG. 22), and generates route data 70a shown in FIG.

  And the information terminal 1 acquires the display information of each guidance point of the route data 70a from the guidance point information 40a, and displays the list on the display unit 14 in the order of the route. At this time, as described above, information on each guide point is highlighted according to the current location.

FIG. 25 is a diagram illustrating an example of highlight display.
FIG. 25A is a display screen example until the arrival at the first guidance point “Omotesando” (station) (when the next guidance point is “Omotesando”). Whether the information terminal 1 has arrived at the guidance point “Omotesando” (station) is determined by detecting a beacon installed at the station platform of Omotesando. As shown in the figure, the information terminal 1 sets the size of the display area a1 of the next guidance point “Omotesando” (station) to at least another guidance point “Aoyama Street direction ticket gate” (ticket gate), guidance point “A5” ( The size is larger than the size of the display areas a2 and a3 of the exit).
In addition, the size of the display areas a2 and a3 of the guidance point “Aoyama Dori direction ticket gate” (ticket gate) and guidance point “A5” (exit) in the order of the route is determined based on the next guidance point “Omotesando” (station). Display sequentially enlarged. However, the size of the display area a3 of the guide point “A5” (exit) closest to the destination is equal to or does not exceed the size of the display area a1 of the next guide point “Omotesando” (station). That is, the display area is controlled so as to maintain the relationship of “display area a1 ≧ size of display area a3> size of display area a2”.

FIG. 25 (b) shows the time from arrival at the first guidance point “Omotesando” (station) until arrival at the second guidance point “Aoyama street direction ticket gate” (ticket gate) (the next guidance point is “Aoyama It is an example of a display screen (in the case of “street ticket gate”). Whether the information terminal 1 has arrived at the guidance point “Aoyama Dori direction ticket gate” (ticket gate) is determined by detecting a beacon installed near the Aoyama Dori direction ticket gate. As shown in the figure, the information terminal 1 sets the size of the display area a2 of the next guidance point “Aoyama Dori direction ticket gate” (ticket gate) to at least another guidance point “Omotesando” (station) and guidance point “A5” ( The size is larger than the size of the display areas a1 and a3 of the exit).
Further, the display area a1 of the guidance point “Omotesando” (station) far from the destination (already passed) from the next guidance point “Aoyama Street direction ticket gate” (ticket gate) is displayed in a small size.

FIG. 25 (c) shows that after arriving at the second guidance point “Aoyama Street direction ticket gate” (ticket gate) until the third guidance point “A5” (exit) (the next guidance point is “A5 It is an example of a display screen in the case of “”. As shown in the figure, the size of the display area a3 of the next guidance point “A5” (exit) is set to the display area of at least another guidance point “Omotesando” (station) and the guidance point “Aoyama street direction ticket gate” (ticket gate). It is displayed larger than the size of a1 and a2.
In addition, the size of the display areas a1 and a2 of the guidance point “Omotesando” (station) and the guidance point “Aoyama Dori direction ticket gate” (ticket gate) far from the destination on the basis of the next guidance point N3 is uniform. Display smaller.

When the information terminal 1 detects a beacon installed near the A5 exit, it is determined that the information terminal 1 has reached the nearest exit of the destination, and exit guidance is terminated.
If the information terminal 1 detects a beacon (X beacon, Y beacon...) Set as an NG beacon (see FIG. 24), it is determined that the information terminal 1 has deviated from the route, and a warning is given to the effect that the route has deviated. Alternatively, the route is reconstructed from a point that deviates from the route.

  In the above, the example which performs route guidance (exit guidance) to the exit of the station with the best access to the destination was explained. The exit guide is merely an example of application of the present invention, and the present invention can be applied to various other guides (airport premises guidance, commercial facility guidance, road guidance, etc.).

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea disclosed in the present application, and these naturally belong to the technical scope of the present invention.
