Note that the guide device, the guide method, and the guide program according to the present application are not limited by this embodiment. Also, in each of the following embodiments, the same parts and processes are designated by the same reference numerals, and duplicate description will be omitted.

[1. Example of action and effect]
First, the concept of the action and effect exhibited by the terminal device 100, which is an example of the guide device, will be described with reference to FIG. FIG. 1 is a diagram for explaining an example of the action and effect exhibited by the terminal device according to the embodiment. For example, the terminal device 100 is a terminal device such as a smartphone, a tablet terminal, a mobile terminal such as a PDA (Personal Digital Assistant), or a notebook PC (Personal Computer), such as a mobile communication network or a wireless LAN (Local Area Network). A terminal device capable of communicating with an arbitrary server via the network N. Note that the terminal device 100 may be demonstrated by a wearable device or the like instead of a mobile portable terminal such as a smartphone.

  In addition, the terminal device 100 has a function of displaying an image such as a liquid crystal screen or an LED (Light Emitting Diode) screen. When such a terminal device 100 receives an input of a destination from the user, the terminal device 100 acquires a plurality of pieces of guidance information explaining each part of the route to the destination and a plurality of pieces of map information corresponding to the pieces of guidance information. .

  Here, the guidance information is information that explains a part of the route to the destination, and indicates the traveling direction of the user, for example, to guide the portion indicated by the guidance information on the route to the destination. It contains text and text that indicates the target place or object in the direction of travel. Further, the map information is an image of a map displayed together with the guide information, and includes a portion of the route to the destination indicated by the guide information displayed together (hereinafter referred to as corresponding guide information). It is a map image. Further, the map information includes various icons indicating directions and positions for guiding the user.

  The terminal device 100 displays such guide information and corresponding map information, and switches the guide information and the map information in the order along the route according to the operation of the user. For example, the terminal device 100 switches a plurality of pieces of guidance information that gradually show a route from the ticket gate to the destination via the entrance of the station to the destination after the user exits the train. As described above, since the terminal device 100 guides the user to the destination by using the interactive UI (User Interface) whose guide information is changed by the operation of the user, the positioning system such as GPS cannot be used. Also in this case, the user can be guided to the destination by a simple operation by the user who actually viewed the route.

  Here, in the actual guidance, the route to the destination may be congested depending on the time of day, or the route displayed may be unusable due to construction or the like. In addition, even if the guide information is displayed, the user may lose sight of the direction in which to proceed or may detour to a store or the like on the route. In addition, for example, if a user with a disability has a step or stairs on the route indicated by the displayed guidance information, he / she wants to travel to the destination via another route where an elevator or slope exists. There is a request. As a result, in the actual guidance, it is possible that the user goes to the destination via a route different from the route indicated by the guidance information acquired by the terminal device 100.

  However, in the related art, when the position positioning system cannot be used, the position of the user who has left the route cannot be specified, so that new guidance information cannot be automatically acquired. Further, in the conventional technology, when new guidance information is displayed each time the user deviates from the route, the user frequently changes the screen of the terminal device by inputting the current position or destination and checking the route to be taken. I will pay attention to, and cannot guarantee the safety.

  Therefore, the terminal device 100 executes the following guidance process. First, the terminal device 100 displays guidance information indicating a part of the route to the destination. Then, when the first operation is performed, the terminal device 100 displays a portion different from a portion (hereinafter, referred to as a branch point) where another route from the route branches to the same destination. If the displayed guidance information indicates, the guidance information is continuously displayed. On the other hand, when the guidance information displayed when the first operation is performed indicates a branch point, the terminal device 100 changes the displayed guidance information to guidance information indicating another route branched from the branch point. Switch.

  In addition, when a second operation different from the first operation is performed, the terminal device 100 defines the displayed guide information as the guide information among the same routes as the route indicated by the guide information. Switch to guidance information indicating different parts.

  For example, the terminal device 100 detects, as the first operation, an operation of scrolling the displayed guidance information in the horizontal direction of the screen. Further, the terminal device 100 detects, as the second operation, an operation of scrolling the displayed guidance information in the screen vertical direction. Then, when the operation of scrolling the guide information in the screen vertical direction is performed while the guide information indicating the first route is displayed, the terminal device 100 is not displayed on the first route. The guide information indicating the portion closer to the starting point than the portion indicated by the existing guide information or the guide information indicating the portion closer to the destination is switched.

  On the other hand, when the terminal device 100 displays the guide information indicating a portion other than the branch point at which the second route reaching the same destination as the first route branches out of the first route. When the operation of scrolling the guidance information in the horizontal direction of the screen is performed, the guidance information indicating the first route is continuously displayed. Then, when the guidance information indicating the portion including the branch point of the first route is displayed, the terminal device 100 performs the first guidance if the operation of scrolling the guidance information in the horizontal direction of the screen is performed. The guidance information indicating the route is switched to the guidance information indicating the second route.

  Hereinafter, an example of the functional configuration and operational effects of the terminal device 100 that realizes the above-described guidance process will be described with reference to the drawings. In the following description, an example of processing in which the terminal device 100 displays the guidance information C21 to C27 and the map information C11 to C17 will be described. In the following description, the guide information C21 to C27 may be collectively referred to as guide information C20, and the map information C11 to C17 may be collectively referred to as map information C10.

FIG. 3 is a flowchart illustrating an example of the flow of processing executed by the terminal device according to the embodiment.

  First, the operation control unit 152 determines whether or not the destination is input by the user (step S101), and if not input (step S101: No), waits until input. Then, when the destination is input from the user (step S101: Yes), the operation control unit 152 outputs the input destination to the request unit 151. In such a case, the request unit 151 transmits the input destination to a server (not shown) and requests the guide information C20 and the map information C10 (step S102).

  As a result, the acquisition unit 154 acquires the guide information C20 to the destination and the map information C10 from the server (step S103). More specifically, the acquisition unit 154 indicates a first route to the destination, and a second route and a third route that branch from the middle of the first route to the same destination. The guidance information C21 to C27 is acquired, and the acquired guidance information C21 to C27 is stored in the guidance information database 121. In addition, the acquisition unit 154 acquires map information C11 to C17 corresponding to each guidance information C21 to C27 and stores the acquired map information C11 to C17 in the map information database 122.

  In addition, the display unit 155 displays the guide information at the beginning of the route and the corresponding map information (step S104). For example, the display unit 155 reads the guidance information C20 and the map information C10 from the guidance information database 121 and the map information database 122, and as shown in the first state of FIG. 1, "Please go up the stairs toward the central ticket gate. Guidance information C21 including text information indicating a target such as "," and map information C11 in which an arrow-shaped icon indicating the traveling direction of the user is arranged are displayed.

  Returning to FIG. 3, the operation control unit 152 determines whether or not an upward scroll for scrolling the guidance information C20 upward in the screen is detected as the second operation (step S105). Then, when the operation control unit 152 detects the upward scroll operation (step S105: Yes), the switching unit 156 displays the displayed guide information C20 and the corresponding map information C10 on the guidance to be displayed next. The information C20 is switched to the corresponding map information C10 (step S106).

  For example, when the switching unit 156 is in the first state of FIG. 1, when the operation of scrolling the guidance information C21 in the upper direction of the screen is performed by the user's finger F10, as shown in the second state, The guide information C21 is switched to the guide information C22 including text information such as "Please exit the central ticket gate", that is, the guide information C22 displayed next to the guide information C21 in the first route. Further, the switching unit 156 switches from the map information C11 to the map information C12 including the icon indicating the position of the central ticket gate.

  Similarly, when the operation of scrolling the guide information C22 upward in the screen is performed from the second state, the switching unit 156 displays the guide information C22, “From the central ticket gate to A, as shown in the third state. Switch to guidance information C23 including text information such as "Go to the mall". In addition, the terminal device 100 switches from the map information C12 to the map information C13 including an arrow-shaped icon indicating the moving direction from the central ticket gate to the A mall.

  Returning to FIG. 3, when the up scroll is not detected (step S105: No), the operation control unit 152 determines whether or not the down scroll for scrolling the guidance information C20 in the down direction of the screen is detected (step). S107). Then, when the down scroll operation is detected by the operation control unit 152 (step S107: Yes), the switching unit 156 sets the displayed guide information C20 and the corresponding map information C10 to the previous guide information.

  For example, the switching unit 156 switches the guidance information C23 to the guidance information C22 as shown in the second state when the operation of scrolling the guidance information C23 downward in the screen is performed from the third state of FIG. , The map information C13 is switched to the map information C12. Similarly, when the operation of scrolling the guidance information C22 downward in the screen is performed from the second state, the switching unit 156 switches the guidance information C22 to the guidance information C21 as shown in the first state, and the map is displayed. The information C12 is switched to the map information C11.

  Returning to FIG. 3, when the downward scroll is not detected (step S107: No), the operation control unit 152 determines whether or not the horizontal scroll for scrolling the guidance information C20 in the horizontal direction of the screen is detected (step S107). S109). When the horizontal scroll is detected by the operation control unit 152 (step S109: Yes), the switching unit 156 determines whether or not another route branches from the portion indicated by the displayed guidance information C20. (Step S110).

  Then, when another route branches off from the portion indicated by the displayed guidance information C20 (step S110: Yes), the switching unit 156 changes the displayed guidance information C20 to the guidance information C20 for the other route. (Step S111). More specifically, the switching unit 156 indicates the head portion of the route that branches the displayed guidance information C20 from the route indicated by the displayed guidance information (hereinafter referred to as the original route). Switch to guidance information C20. Then, the switching unit 156 switches the displayed map information C10 to the map information C10 corresponding to the guidance information C20 switched in step S111 and displays it (step S112).

  For example, in the example shown in FIG. 1, the second route and the third route are branched from the portion indicated by the guidance information C22 in the first route. Therefore, when the operation of scrolling the guidance information C22 in the left direction of the screen as the first operation from the second state is performed by the user's finger F10, the switching unit 156 performs the guidance as shown in the fourth state. The information C22 is switched to the guidance information C24 including text information such as "Please exit the north ticket gate". Further, the terminal device 100 switches from the map information C12 to the map information C14 including the icon indicating the position of the north ticket gate. That is, when the horizontal scroll is performed while the guidance information C22 indicating the range including the branch point of the first route is displayed, the switching unit 156 changes the displayed guidance information C22 to the first guidance information C22. The guide information C23 indicating the beginning of the route 2 is switched to.

  Similarly, when the operation of scrolling the guidance information C24 in the left direction of the screen is further performed by the user's finger F10 from the fourth state, the switching unit 156 changes the guidance information C24 to the fifth state as shown in FIG. , Guidance information C26 including text information such as "Please exit the south ticket gate". Further, the terminal device 100 switches from the map information C14 to the map information C16 including the icon indicating the position of the south ticket gate. That is, when the horizontal scroll is performed while the guide information C24 indicating the range including the branch point of the second route is displayed, the switching unit 156 changes the displayed guide information C24 to the first guide information C24. It switches to the guidance information C26 indicating the beginning of the route of No. 3.

  In addition, when the upward scrolling operation of the guidance information C24 is performed from the fourth state, the terminal device 100 displays "from the north ticket gate to the first entrance / exit" as shown in the sixth state. Switch to guidance information C25 including text information such as "please". In addition, the terminal device 100 switches from the map information C14 to the map information C15 including an arrow-shaped icon indicating the moving direction from the north ticket gate to the first doorway.

  In addition, in the terminal device 100, when the upward scroll operation of the guidance information C26 is performed from the fifth state, as shown in the seventh state, from the guidance information C26, “From the south ticket gate to B Plaza” The guide information C27 including text information such as ". In addition, the terminal device 100 switches from the map information C16 to the map information C17 including an arrow-shaped icon indicating the direction of movement from the south ticket gate to the B plaza. That is, the terminal device 100 switches between the guidance information C24 and C25 indicating the second route and the guidance information C26 and C27 indicating the third route in response to the vertical scroll operation (steps S105 and S106 in FIG. 3). ).

  Returning to FIG. 3, when it is determined that the horizontal scroll is not detected (step S109: No), the operation control unit 152 determines whether or not a predetermined ending operation for ending the guidance process is performed (step S113). ). Then, when the ending operation is performed (step S113: Yes), the operation control unit 152 outputs the ending guide to the effect that the guiding process is ended from the output unit 140 (step S114), and ends the guiding process.

  On the other hand, when the ending operation is not performed (step S113: No), the operation control unit 152 executes step S105. It should be noted that the operation control unit 152 executes steps S106, S108, and S112 when the horizontal scroll is performed and when another route does not branch from the portion indicated by the displayed guidance information C20. (Step S110: No), step S113 is executed.

[4. Displaying detailed information)
The terminal device 100 described above displays a plurality of pieces of guidance information C20 indicating the route to the destination in stages, and sequentially switches the guidance information C20 in accordance with the scroll operation. Here, depending on the part of the route to the destination indicated by the guidance information C20, the route may be complicated and it may be difficult to guide the user. Therefore, the terminal device 100 may display, in addition to the guidance information C20, one or more pieces of detailed information C40 indicating the route in more detail than the guidance information C20.

  For example, FIG. 4 is a diagram for explaining an example of detailed information displayed by the terminal device according to the embodiment. In the example shown in FIG. 4, as the detailed information C40, an example in which detailed information C41 to C43 indicating the route of the portion indicated by the guidance information C25 in more detail is displayed is described. For example, the terminal device 100 displays the guidance information C25 and the corresponding map information C15, as shown in the first state of FIG. Then, when the user's finger F10 scrolls the guide information C25 upward in the screen, the terminal device 100 switches the guide information C25 to the guide information C28 as shown in the second state, and maps the map information C15 to the map information C15. Switch to information C18.

  Here, when the guidance of the portion indicated by the guidance information C25 on the second route is complicated, the terminal device 100 acquires the detailed information C41 to C43 together with the guidance information C25. Further, when the terminal device 100 acquires the detailed information C40, the terminal device 100 displays an icon C30 for displaying the detailed information C40, as shown in the first state.

  Then, when the icon C30 is tapped with the finger F10 of the user, the terminal device 100 displays the detailed information C41 indicating the leading portion of the portion indicated by the guidance information C25. Further, when the up scroll is performed while the detailed information C41 is displayed, the terminal device 100 switches the detailed information C41 to the detailed information C42 as shown in the fourth state. Further, when the upper scroll operation is performed while the detailed information C42 is displayed, the terminal device 100 switches the detailed information C42 to the detailed information C43 as shown in the fifth state. Then, when the upper scroll operation is further performed while the detailed information C43 is displayed, the terminal device 100 ends the display of the detailed information C40 and displays the guidance information C25 as shown in the second state. Next displayed guidance information C28 and corresponding map information C18 are displayed.

  That is, when the upper scroll operation is performed, when the detailed information C41 and C42 indicating other than the end of the portion indicated by the guidance information C25 are displayed, the terminal device 100 changes the detailed information C41 and C42 to other details. The information is switched to C42 and C43. When the upper scroll operation is performed, if the detailed information C43 indicating the end of the portion indicated by the guidance information C25 is displayed, the terminal device 100 ends the display of the detailed information C40, and the guidance information C25. The guidance information C28 displayed next to is displayed.

  Note that the terminal device 100 displays the icon C31 for switching the detailed information C40 to the guidance information C20 while the detailed information C40 is displayed, as shown in the third state to the fifth state. Then, when the user taps the icon C31 during the display from the third state to the fifth state, the terminal device 100 cancels the display of the detailed information C41 to C43 and displays the guide information as shown in the first state. Display C25.

  In this way, the terminal device 100 displays the detailed information C40 indicating the route in more detail than the guidance information C20. Therefore, the terminal device 100 can appropriately guide the user even when the portion of the route to the destination indicated by the displayed guidance information C20 is complicated.

[5. Display of target information]
In the example shown in FIG. 4, the terminal device 100 did not display the guidance information C20 when displaying the detailed information C40. However, the embodiment is not limited to this. For example, the terminal device 100 may display the detailed information C41 to C43 and continue to display the guidance information C25 indicating the part indicated by the detailed information C41 to C43, and the guidance information C25 of the second route indicates the guidance information C25. The target information C50 indicating the beginning and end of the portion may be displayed simultaneously with the detailed information C40.

  For example, FIG. 5 is a diagram for explaining an example of target information displayed by the terminal device according to the embodiment. Note that the processing shown in the first state and the second state shown in FIG. 5 is the same as the processing shown in the first state and the second state shown in FIG. 4, and a description thereof will be omitted. Further, in the example shown in FIG. 5, as the target information C50, the target information C51 indicating the beginning of the portion indicated by the guidance information C25 and the target information C51 indicating the end are described.

  For example, when the icon C30 is tapped by the user's finger F10 in the first state, the terminal device 100 displays the detailed information C41 as shown in the third state. Further, the terminal device 100 displays the target information C51 indicating the beginning of the portion indicated by the guidance information C25 and the target information C52 indicating the end of the portion indicated by the guidance information C25 on the second route. For example, in the case where the guidance information C25 includes the text "Go from the north ticket gate to the first doorway", the terminal device 100 includes the target information C51 including the text "From the north ticket gate" and the "first doorway". The target information C52 including the text "up to" is displayed together with the detailed information C41.

  In addition, when the up scroll operation is performed in the third state, the terminal device 100 displays the detailed information C41 and the detailed information C42 while the target information C51 and C52 are still displayed as shown in the fourth state. Switch to. When the up scroll operation is performed in the fourth state, the terminal device 100 displays the detailed information C42 and the detailed information C43 while the target information C51 and C52 are still displayed as shown in the fifth state. Switch to. Then, when the terminal device 100 further displays the end of the portion indicated by the guidance information C25, that is, the guidance information C43 indicating the portion indicated by the target information C52, and further scrolls up, the second As shown in the state, the display of the detailed information C40 and the target information C50 is canceled and the guidance information C28 is displayed.

  In this way, when the head of the route indicated by the guidance information C20 and the target information C50 indicating the target are displayed separately from the detailed information C40, it is possible to show the user an index of where he is heading. Therefore, the terminal device 100 can more appropriately guide the user to the destination.

[6. Timing of acquisition of guidance information)
Here, in the above-described embodiment, the terminal device 100 displays all the guidance information C21 to C23 indicating the first route to the destination, and the second route and the third route branched from the first route. All the guidance information C24 to C27 shown is acquired in advance, and the guidance information to be displayed is switched according to the operation of the user. However, the embodiment is not limited to this. That is, the terminal device 100 may acquire the guidance information indicating an arbitrary area of the route to the destination at an arbitrary timing.

  For example, FIG. 6 is a diagram for explaining an example of a range of guidance information acquired by the terminal device according to the embodiment. In the example shown in FIG. 6, guidance information # 1 to # 7 indicating the first route to the destination, and a second route branched from the portion indicated by the guidance information # 3 in the first route are shown. The guide information # 8 to # 10, the guide information # 11 and # 12 indicating the third route branched from the part indicated by the guide information # 3 in the first route, and the guide information # 3 in the first route. The guide information # 13 and # 14 indicating the fourth route branched from the indicated portion is described.

  For example, in the terminal device 100, when the destination is input and the route to the destination is searched, the guide information # 1 to # 3, # 8, # shown in FIG. 11 and # 13 are acquired. That is, the terminal device 100 has branched the guide information # 1 and the guide information # 2 indicating the range until the other route branches in the first route, the guide information # 3 indicating the location where the other route branched, and the branch. Guidance information # 8, # 11, # 13 indicating the beginning of each route is acquired. Then, the terminal device 100 switches the guide information # 1 to # 3 in accordance with the vertical scroll, and when the guide information # 3 is displayed when the horizontal scroll is performed, the guide information # 3 is displayed. Switch to any of the guidance information # 8, # 11, and # 13.

  In addition, when the guide information # 3 is displayed when the vertical scroll is performed, the terminal device 100 displays the first route indicated by the guide information # 3 as shown in FIG. 6B. Of these, guidance information # 4 to # 7 indicating a portion preceding the portion indicated by guidance information # 3 is further acquired.

[7. Operation to detect]
In the above-described embodiment, the terminal device 100 switches the displayed guidance information C20 to another guidance information C20 indicating the same route in response to an operation of scrolling the guidance information C20 in the screen up direction or the screen down direction. The displayed guidance information C20 is switched to the guidance information C20 indicating another route in accordance with the operation of scrolling the guidance information C20 in the horizontal direction of the screen. However, the embodiment is not limited to this, and the terminal device 100 switches the displayed guidance information C20 to the guidance information C20 indicating the same route or another route according to an arbitrary operation. Good.

  For example, the terminal device 100 measures the direction in which the user shakes the terminal device 100, using a sensor that measures impact or acceleration. Then, when the user shakes the terminal device 100 in the vertical direction, the terminal device 100 may switch the displayed guide information C20 to another guide information C20 indicating the same route. Further, the terminal device 100 may switch the displayed guide information C20 to the guide information C20 indicating another route when the user shakes the terminal device 100 in the lateral direction.

  In addition, the terminal device 100 switches the displayed guide information C20 to another guide information C20 indicating the same route in response to an operation of scrolling the guide information C20 in the horizontal direction of the screen, and sets the guide information C20 to the screen vertical direction. The displayed guidance information C20 may be switched to guidance information C20 indicating another route in accordance with the operation of scrolling in the direction.

  Further, the terminal device 100 may change the first operation and the second operation according to the traveling direction of the user. For example, the terminal device 100 scrolls the guidance information C20 in the upper direction of the screen when the guidance information C20 for the route that directs the user is displayed and the route for turning the user left is branched. At this time, when switching to another guidance information C20 indicating the same route and scrolling the guidance information C20 in the left direction of the screen, guidance information C20 indicating another route, that is, guidance indicating a route for the user to turn left.

For example, the terminal device 100 may output the guidance information C20 including text as shown in FIG. 1, or may output the guidance information C20 including voice for guiding the user. For example, the terminal device 100 may output a voice such as “please exit the central ticket gate” when switching the guidance information C21 to the guidance information C22. Further, the terminal device 100 may output vibration or the like indicating the traveling direction of the user.

  Further, the terminal device 100 may indicate the direction in which the user should proceed in an azimuth such as "east direction" or "west direction", and a simple direction such as "left direction" or "right direction" based on the direction of the user. It may be indicated in any direction. In addition, the terminal device 100 follows the route indicated by the guidance information C20 in which the user is displayed, when the position of the user can be measured or when the geomagnetism can be detected by using a magnetic sensor or the like. Is determined. Then, the terminal device 100 outputs a voice or vibrates the terminal device 100 when the user moves in the wrong direction or when the user moves in the right direction. You may be notified of the direction to go. Further, after outputting the guidance information C20, the terminal device 100 outputs a voice to call the user's attention when the user moves in a direction different from the correct direction by a predetermined distance or more. The terminal device 100 may be vibrated. When the user wears a wearable device such as a clock-type terminal device that can vibrate, the terminal device 100 may vibrate the wearable device to call the user's attention.

[10. Interlocking with positioning system)
The terminal device 100 described above switches the guidance information according to the operation by the user. However, the embodiment is not limited to this. For example, the terminal device 100 may switch to the guidance process using the position positioning system when the user moves from the underground to the ground and the position positioning system such as GPS becomes available. Further, the terminal device 100 may specify the current position of the user by using the position positioning system and display the guidance information indicating the portion corresponding to the specified position.

[11. Other Embodiments]
Note that the above-described embodiment is merely an example, and the present invention also includes the following exemplified embodiments and other embodiments. For example, the functional configuration, the data structure, the order and contents of the processes shown in the flowchart in the present application are merely examples, and the presence or absence of each element, the arrangement and order of the process execution, and the specific contents can be appropriately changed. . For example, the guidance process and the function of selecting a target described above are realized as a device, a method, or a program in a terminal realized by a smartphone application or the like, in addition to being realized by the terminal device 100 as exemplified in the above embodiment. You can also

  In addition, it is general that each of the processing units 151 to 156 configuring the terminal device 100 is further realized by an independent device.

In addition, the terminal device 100 acquires and displays the guidance information C20 to be displayed from the distribution server. Then, the terminal device 100 notifies the distribution server of the operation content each time the user operates the terminal device 100. In such a case, when the user performs the second operation, the distribution server distributes to the terminal device 100 other guide information C20 indicating the same route as the distributed guide information C20. On the other hand, when the user performs the first operation, the distribution server distributes, to the terminal device 100, the guidance information C20 indicating a route other than the already-delivered guidance information C20. As a result, the terminal device 100 can appropriately guide the user by outputting the guidance information C20 received from the distribution server.

  When the distribution server and the terminal device 100 cooperate with each other to execute the guidance process, the distribution server may distribute the guidance information C20 at an arbitrary granularity. For example, when the destination is searched, the distribution server may distribute the guidance information C21, C22, C24, C26 first, or may distribute all the guidance information C21 to C27 in advance.

  In the above description, an example in which the second route and the third route that reach the same destination as the first route branch from the first route has been described. Here, the second route and the third route do not have to reach the same destination as the first route. Further, the above-mentioned "same destination" does not necessarily mean that the positions are exactly the same. For example, the first route, the second route, and the third route may be routes that lead to entrances and exits at different positions in the same facility. Further, the first route, the second route, and the third route may be routes leading to coffee shops at different positions, for example.

  When the route to the destination is searched, the terminal device 100 indicates the range until the other route branches out of the routes to the destination and the location where the other route branches off 1 One or more pieces of guidance information C20 and guidance information C20 indicating the head portion of another route are acquired. Then, when the guidance information C20 indicating the branch point is displayed when the first operation is performed, the terminal device 100 uses the displayed guidance information C20 to guide the leading portion of another route. Switch to information C20.

  Further, when the guidance information C20 indicating the branch point is displayed when the second operation is performed, the terminal device 100 indicates the guidance information C20 that is displayed among the routes to the destination. Further, the guide information C20 indicating the portion ahead of the location is further acquired and displayed. On the other hand, when the guide information C20 indicating the leading part of another route is displayed when the second operation is performed, the terminal device 100 displays the guide information displayed among the other routes. Further, the guidance information C20 indicating the portion preceding the portion indicated by C20 is acquired. Therefore, the terminal device 100 can reduce the amount of data acquired when searching for the route to the destination, and thus can improve the response to the operation of the user in the interactive guidance.

  Further, the terminal device 100 acquires all the guidance information C20 indicating the route to the destination and all the guidance information C20 indicating the route branched from the route. Therefore, the terminal device 100 can appropriately guide the user even after it is difficult to communicate with the server that distributes the guidance information C20 after starting the guidance.

  Further, the terminal device 100 displays, together with the guidance information C20, one or more pieces of detailed information C40 indicating the portion indicated by the guidance information C20 in more detail than the guidance information C20. Therefore, the terminal device 100 can appropriately guide the user to the destination even if the portion of the route to the destination indicated by the guidance information C20 is complicated.

  Further, when the detailed information C40 indicating a portion other than the end of the portion indicated by the guidance information C20 is displayed when the second operation is performed, the terminal device 100 replaces the displayed detailed information C40 with another information. Switch to detailed information C40. On the other hand, if the detailed information C40 indicating the end of the portion indicated by the guidance information C20 is displayed when the second operation is performed, the terminal device 100 displays the detailed information C40 on the guidance to be displayed next. Switch to information C20. Therefore, the terminal device 100 can continuously guide the user to the destination.

  Further, the terminal device 100 displays the guide information C20 and the map information C10 corresponding to the guide information C20.
