FIG. 1 is a block diagram showing a schematic configuration of the display device according to the embodiment, and FIG. 2 is a flowchart showing the operation of the display device. FIG. 3 is a diagram illustrating a display example of the same symbol mark according to the embodiment displayed on the display unit in the operation, and FIG. 4 is a diagram illustrating a display example of the same symbol mark.

  The display device S according to the embodiment is a display device S that can be carried by a user. As shown in FIG. 1, the display device S is configured by, for example, a liquid crystal display and the like, and is an example of a display unit having a display screen for displaying a map. And a system control unit 15 as an example of a determination unit and an example of a display control unit.

  The display device S is connected to a storage device 11 including a non-volatile recording medium such as a hard disk drive so that data can be exchanged. As shown in FIG. 1, the recording medium of the storage device 11 may be moved together when there is a person who moves with the user carrying the display device S (hereinafter referred to as a companion). Symbol mark data M2 as a plurality of mark materials that are the same symbol mark according to the embodiment to be represented is stored.

  On the other hand, the system control unit 15 has a CPU (Central Processing Unit) read and execute a program stored in a ROM (Read Only Memory) or the like, whereby the position information acquisition unit 16 as an example of the position information acquisition unit, It functions as a companion presence / absence information acquisition unit 18 as an example of a person presence / absence information acquisition unit, a symbol mark acquisition unit 19 as an example of the same symbol mark acquisition unit, and a display control unit 20 as an example of a display control unit.

  The position information acquisition unit 16 acquires the current position information of the display device S using, for example, GPS (Global Positioning System). Note that the current position information may be acquired as the position information acquisition unit 16 by the user inputting the position information.

  The accompanying person presence / absence information acquiring unit 18 acquires accompanying person presence / absence information related to the presence / absence of the accompanying person. More specifically, the accompanying person presence / absence information acquiring unit 18 acquires, for example, the number of accompanying persons input by the user.

  For example, when five family members including a father as an example of a user carrying the display device S according to the present application move together, the father has four accompanying persons. Therefore, the companion presence / absence information acquisition unit 18 in the display device S can accompany the father who is the user by inputting “4” in the display device S carried by the father. The number of people “4” is acquired.

  In the embodiment, “to move together” means that the user moves with the accompanying person in an area such as a guide route where the user is scheduled to move, a shopping center or an entertainment facility, For example, even if a part of the family mentioned in the above example is temporarily separated, the act of joining and resuming movement after the separation is also included in the “move together” .

  And the system control part 15 determines the presence or absence of a companion based on the companion presence or absence information regarding the presence or absence of a companion acquired by the companion presence or absence information acquisition part 18, for example, the above-mentioned number of persons. Incidentally, when the above-mentioned number of persons “4” is acquired by the accompanying person presence / absence information acquiring unit 18, it is determined that “accompanying person exists”.

  Next, the symbol mark acquisition unit 19 stores symbol mark data corresponding to the same symbol mark expressing that the user and the accompanying person are moving together when the user is accompanied by the accompanying method by a method described later. Obtained from the device 11.

  Note that, as the symbol mark or the same symbol mark according to the embodiment, for example, an animal (more specifically, for example, a turtle) character is used. In other words, a plurality of symbol mark data M2 using the animal character is stored in the storage device 11, and the symbol mark M2 is acquired by the display device S and used as the symbol mark or the same symbol mark. The symbol mark data M2 includes a plurality of data having different sizes for each type of animal. The symbol mark acquisition unit 19 is configured to generate the symbol mark data M2 having different sizes according to the total number of the user and the accompanying person, for example, by superimposing or linking the symbol mark data M2. Symbol mark data corresponding to the same symbol mark is acquired. Each of the symbol mark data M2 constituting the acquired symbol mark data is symbol mark data M2 using the same kind of animal character. Further, symbol mark data corresponding to the same symbol mark generated using the symbol mark data M2 having different sizes is acquired so that the user and the accompanying person can be easily identified. Furthermore, when there is no accompanying person and the user moves alone, for example, the largest single symbol mark data M2 is acquired as a symbol mark expressing that the user moves alone.

  In the present embodiment and the examples described later, when the display unit 12 visualizes what is acquired using the “symbol mark data M2”, it is “symbol mark” or “same symbol mark”. It becomes.

  Furthermore, “acquiring” the same symbol mark in the embodiment means that, as described above, a plurality of symbol mark data M2 that are originally different from each other are overlapped or linked to each other. In addition to the case where the symbol mark acquisition unit 19 acquires “generated” symbol mark data corresponding to “mark”, the symbol mark data M2 itself has a form in which the symbol mark data M2 is superimposed or linked. The symbol mark data M2 corresponding to the “same symbol mark” is stored as “data” in advance, for example, in the storage device 11 or the like in the number corresponding to the number of accompanying persons and the variation of the display mode. The symbol mark acquisition unit 19 includes “reading” according to the presence / absence and the number of persons. In the following description, an embodiment in which the symbol mark acquisition unit 19 acquires data generated using a plurality of symbol mark data M2 as symbol mark data corresponding to the same symbol mark described above will be described.

  On the other hand, the display control unit 20 determines whether to display a symbol mark or the same symbol mark based on the accompanying person presence / absence information acquired by the accompanying person presence / absence information acquiring unit 18. Further, when it is determined to display the same symbol mark, the symbol mark acquisition unit 19 acquires the data generated as the symbol mark data corresponding to the same symbol mark corresponding to the number of persons. Then, either the symbol mark or the same symbol mark is displayed on the display unit 12 based on the current position information acquired by the position information acquisition unit 16. Furthermore, when the movement of the user, that is, the movement of the display device S carried by the user is confirmed by the current position information acquired by the position information acquisition unit 16, in other words, the current acquired by the position information acquisition unit 16 When the position information is updated, the display position of the symbol mark or the same symbol mark on the display screen of the display unit 12 is moved according to the movement.

  When the display control unit 20 determines the presence or absence of the accompanying person based on the number of accompanying persons input by the user as described above, the display control unit 20 displays the same symbol mark until the inputted number of persons is updated to “0”. Let That is, for example, when the number of accompanying persons is changed from “4” to “0”, the display control unit 20 changes the display of the same symbol mark to the display of the symbol mark.

  Next, the operation of the display device S according to the embodiment will be described with reference to FIGS.

  As shown in FIG. 2, the operation of the display device S according to the embodiment is as follows. First, a guidance route display application (hereinafter simply referred to as a walking navigation application) according to the embodiment that guides walking movement based on a user operation. ) Is activated by the system control unit 15 (step S101).

  Next, the system control unit 15 determines whether or not the current position information indicating the current position of the display device S carried by the user has been acquired (step S102), and the position information acquisition unit 16 determines the current position information. If the position information has been acquired (step S102; YES), the operation proceeds to step S104 described later. On the other hand, when the current position information has not been acquired (step S102; NO), the system control unit 15 causes the position information acquisition unit 16 to acquire the current position information (step S103) and proceeds to the operation of step S102. .

  Next, the system control unit 15 includes information necessary for displaying the symbol mark according to the embodiment or the same symbol mark on the display screen of the display unit 12 (specifically, for example, number information indicating the number of accompanying persons). Or current position information indicating the current position of the user) is checked (step S104). If all the necessary information has been input (step S104; YES), the process proceeds to the operation of step S106 described later. On the other hand, if there is uninput information (step S104; NO), Wait until input information is input (step S105).

  Next, the companion presence / absence information acquisition unit 18 of the system control unit 15 determines the presence / absence of a companion accompanying the user based on the number of persons information acquired in steps S104 and S105 (step S106). If there is (Step S106; YES), the operation proceeds to Step S107, which will be described later.

  Next, as the operation of step S107, the display control unit 20 of the system control unit 15 is accompanied by a companion as the operation of step S107 (see step S106; YES). The same symbol mark indicating “together” is displayed on the display screen of the display unit 12. At this time, as described above, the system control unit 15 causes the symbol mark acquisition unit 19 to acquire symbol mark data corresponding to the same symbol mark corresponding to the number of accompanying persons. That is, if the system control unit 15 determines that there is a companion, the system control unit 15 determines the same symbol mark as a mark to be displayed, and generates it using symbol mark data M2 having a different number of sizes according to the number of the companion. The symbol mark acquisition unit 19 acquires the same symbol mark.

  More specifically, for example, when the accompanying person is, for example, one person, the symbol mark acquisition unit 19 uses the symbol mark data M2 having two different sizes to superimpose the symbol mark data generated on each other. The symbol mark data corresponding to the same symbol mark for expressing that the accompanying person is one person is acquired. Further, when there are two accompanying persons, for example, the two accompanying persons are the symbol mark data generated by connecting the symbol mark data M2 having three different sizes to each other. It is acquired as symbol mark data corresponding to the same symbol mark for expressing the above. When there are three or more accompanying persons, for example, three symbol mark data M2 having different sizes are connected to each other, and there are more accompanying persons. A symbol mark corresponding to the same symbol mark for expressing that the symbol mark data generated by adding a symbol indicating the effect (for example, “...”) Indicates that there are three or more accompanying persons. Get as data. Furthermore, the symbol mark data corresponding to the same symbol mark acquired by any of the above methods is displayed by the system control unit 15 (that is, the same symbol mark is displayed on the display screen of the display unit 12 and will be described later). In the display control including moving the displayed same symbol mark in accordance with the movement of the user), each symbol mark that is treated as one data and constitutes the symbol mark data corresponding to the same symbol mark M2 is handled as an integral part of the symbol mark data corresponding to the same symbol mark. That is, for example, the symbol mark data composed of the symbol mark data M2 indicating the user and the symbol mark data M2 indicating the accompanying person is displayed after the same corresponding symbol mark is once displayed on the display screen of the display unit 12. Even if the user and the accompanying person are separated or approached to some extent, the display distance between the symbol mark data M2 does not change depending on them (in other words, the accompanying person's movement) And without depending on the change in position), the display mode as the same symbol mark is unchanged.

  The display control unit 20 displays the same symbol mark indicated by the symbol mark data generated and acquired in this way on the display screen of the display unit 12. At this time, the display control unit 20 displays the same symbol mark at a position on the display screen corresponding to the current position indicated by the current position information acquired by the position information acquisition unit 16 (see steps S102 and S103). .

  In addition to the case where symbol mark data corresponding to the same symbol mark is newly generated by the above-described method, as described above, the symbol mark data M2 originally having the form as the same symbol mark is used as one data. For example, the storage device 11 or the like is stored in advance in the number corresponding to the number of persons and the display mode, and the symbol mark acquisition unit 19 performs “reading” according to the presence / absence of the accompanying person and the determination result of the number. It can also be configured to be used for display.

  More specifically, as illustrated in FIG. 3, the display control unit 20 includes the map 6 around the current position indicated by the current position information acquired by the position information acquisition unit 16 and the same symbol mark 26 (described later). In addition, the same symbol mark 26 corresponding to the symbol mark data consisting of the symbol mark data M2 corresponding to the symbol mark 25 for displaying the user himself and the symbol mark data M2 corresponding to the symbol mark 25a for displaying the accompanying person) Are displayed on the display screen of the display unit 12. When the current position information of the user is updated according to the movement of the user, the display position of the same symbol mark 26 displayed on the display screen is moved according to the movement of the user.

  As the same symbol mark 26, the same symbol mark 26 made of an animal character such as a turtle is used as described above. That is, as illustrated in FIG. 4, symbol mark data M2 indicating the user himself and corresponding to the symbol mark 25 which is the animal character, and corresponding to the symbol mark 25a indicating the accompanying person and the animal character. With the symbol mark data M2, symbol mark data corresponding to one (integral inseparable) identical symbol mark 26 is generated.

  In the above, symbol mark data corresponding to the same symbol mark 26 using the symbol mark data M2 having different sizes corresponding to the number of accompanying persons (that is, turtle symbol mark data M2 having different sizes). However, for example, the user inputs information indicating the relationship between the accompanying person and the user, and generates symbol mark data corresponding to the same symbol mark 26 based on the input information indicating the relationship. The symbol mark data M2 used for the determination may be determined.

  Specifically, for example, when the relationship between the user and the accompanying person is a parent-child relationship, it is determined that symbol mark data corresponding to the same symbol mark 26 is generated using symbol mark data M2 having different sizes. More specifically, in the case of a parent-child relationship, as illustrated in FIG. 4A, a large turtle symbol mark indicating “parent turtle” is used as a symbol mark 25 indicating a user, and “ Symbol mark data M2 corresponding to each of the symbol marks 25 and 25a is determined to overlap the small turtle symbol mark 25a indicating "child turtle" to form the same symbol mark 26, and the symbol mark corresponding to the same symbol mark 26 Data is generated.

  When the relationship with the accompanying person is a friend relationship (that is, the mutual relationship is usually equal), it is determined that the symbol mark data corresponding to the same symbol mark 26 is generated using the symbol mark data M2 having the same size. That is, as illustrated in FIG. 4B, the symbol marks 25 and 25a having the same size indicating the “turtle” are arranged to be the same symbol mark 26 arranged in a row in the front and rear. Symbol mark data M2 corresponding to each is determined, and symbol mark data corresponding to the same symbol mark 26 is generated.

  Furthermore, when the relationship with the accompanying person is a lover relationship or a marital relationship, it is determined that symbol mark data corresponding to the same symbol mark 26 is generated using symbol mark data M2 having different sizes, and the symbols Symbol mark data corresponding to the same symbol mark 26 in which the symbol marks 25 and 25a respectively corresponding to the mark M2 are arranged on the left and right may be generated.

  As another form of the same symbol mark 26, when there are a plurality of accompanying persons other than the user, for example, as shown in FIGS. 4C to 4E, the symbol marks 25a indicating the plurality of accompanying persons are used. It is preferable to display the same symbol mark 26 including.

  More specifically, for example, FIG. 4C illustrates the same symbol mark 26 corresponding to a case where a user who is a father inputs that there are two accompanying siblings (or sisters) as children. As shown, the symbol mark 25a including two tortoises as a symbol mark 25a indicating two accompanying children, a turtle smaller than the symbol mark 25 and a smaller turtle accompanying it (a turtle facing sideways in FIG. 4C). The symbol mark data M2 corresponding to the symbol mark data M2 corresponding to the user and the symbol mark data M2 corresponding to the user are connected to the symbol mark data M2 as symbol mark data corresponding to the same symbol mark 26. The acquisition unit 19 is preferably acquired.

  In addition, as the same symbol mark 26 corresponding to a case where a user who is a father is input that there are, for example, three or more accompanying persons who are children, as shown in FIG. Symbol mark data M2 corresponding to a symbol mark 25a in which a horizontal turtle smaller than the symbol mark 25 is surrounded by a frame as a symbol mark 25a indicating a child of the child, symbol mark data M2 corresponding to the symbol mark 25 corresponding to the user, It is preferable that the symbol mark acquisition unit 19 acquires the symbol mark data generated by superimposing the symbols as symbol mark data corresponding to the same symbol mark 26. In the case illustrated in FIG. 4D, it is possible to display that there are a plurality of accompanying persons while minimizing the occupied area on the display unit 12 as the same symbol mark 26.

  In the case illustrated in FIG. 4D, as symbol mark data M2 corresponding to the symbol mark 25a for displaying the accompanying person, a number corresponding to the actual number of accompanying persons as illustrated in FIG. Symbol mark data M2 corresponding to the symbol mark 25a including a small turtle (two people in the case of FIG. 4E) in the frame may be used.

  In any of the cases shown in FIGS. 4A to 4E, the symbol mark data corresponding to the generated same symbol mark 26 is one in the display control by the system control unit 15 as described above. Each piece of symbol mark data M2 that is treated as one piece of data and constitutes symbol mark data corresponding to the same symbol mark 26 is inseparably constituted of symbol mark data corresponding to the same symbol mark 26.

  On the other hand, the display control unit 20 of the system control unit 15 knows that there is no accompanying person as the step S108 as the operation of the above step S108 (see step S106; NO). Only the symbol mark 25 indicating the position is displayed on the display screen of the display unit 12. More specifically, the display control unit 20 displays on the display screen of the display unit 12 the map 6 around the current position indicated by the current position information and the symbol mark 25 that moves according to the movement state of the user. indicate.

  As described above, according to the operation of the display device S according to the embodiment, when there is a companion who moves together with the user, the symbol mark data corresponding to the same symbol mark 26 indicating that the user moves together. The same symbol mark 26 is displayed on the display screen of the display unit 12 based on the current position of the user, and the display position of the same symbol mark 26 is changed according to the action (movement) of the user. Therefore, it is possible to express that there is another person who performs the same action as the user's own action, and the convenience is improved.

  Next, a more specific example of the display device S according to the present embodiment will be described.

Note that the route information and symbol mark data M2 related to the operation of the display control unit 20 are transmitted from the server SV via the network NW, respectively. The display control unit 20 cooperates with the map display control unit 32 to superimpose the guide route generated using the route information or the like on the map 6 (see FIG. 3) as necessary. Display on the display screen.

(B) Operation of Guide Route Display System Next, the operation of the guide route display system SS according to the first embodiment will be described with reference to FIGS. 6 is a flowchart showing the operation of the guidance route display system according to the first embodiment, FIG. 7 is a diagram illustrating an operation screen according to the first embodiment, and FIG. 8 is displayed on the display screen. It is a figure which shows an example of the guidance route which concerns on 1st Example.

  In the cellular phone MP of the guidance route display system SS according to the first embodiment, the display mode setting operation (see FIG. 6A) such as the symbol mark 25 or the same symbol mark 26 is performed as part of the initial setting operation, for example. Later, a guide route display operation (see FIG. 6B) is performed.

  First, the setting operation of the symbol mark display mode according to the first embodiment will be described with reference to FIG. FIG. 6A is a flowchart showing a setting example of the symbol mark display mode.

  Here, in the first embodiment, as the display mode (display mode) of the symbol mark according to the first embodiment, for example, three display modes of “normal display mode”, “overlapping display mode”, and “continuous display mode” are used. Is defined.

  At this time, the normal display mode is a display mode in which only the symbol mark 25 indicating the user is displayed on the map (similar to the prior art). The overlap display mode includes, for example, a symbol mark 25 indicating a user and a symbol mark 25a indicating a companion so as to overlap each other when there is one companion (FIG. 4A and FIG. 4C). ) Or (d)). This is a display mode in which the same symbol mark 26 is displayed. Further, the continuous display mode includes, for example, a symbol mark 25 indicating a user and a symbol mark 25a indicating one or a plurality of accompanying persons on a map when there are one or more accompanying persons. (See FIG. 4B) This is a display mode in which the same symbol mark 26 is displayed.

  As shown in FIG. 6A, in the guidance route display operation according to the first example, the user first operates the operation unit 13 to activate the walking navigation application (step S201). More specifically, for example, as shown in FIG. 7 (a), the top screen 2 including a plurality of menu items 2a that can be selected by the user is displayed on the display screen of the display unit 12. When the user selects “”, the walking navigation application is activated.

  Next, the companion presence / absence information acquisition unit 18 of the mobile phone MP performs an operation of confirming the number of people who are moving with the user of the mobile phone MP at that time (that is, the presence / absence of the companion and the number of the accompanying people). It performs (step S202). More specifically, the system control unit 33 checks the total number of accompanying persons that the user has input or selected by operating the operation unit 13 (step S202). More specifically, for example, as illustrated in FIG. 7B, the system control unit 33 determines the number of accompanying persons when the setting screen 3 as a walking navigation application is displayed on the display screen of the display unit 12. Check whether it is entered. And the accompanying person presence / absence information acquisition unit 18, in the setting screen 3 shown in FIG. 7B, when one or more numbers are input in the “accompanying person” column, Confirm that exists.

  That is, the accompanying person presence / absence information acquisition unit 18 first determines whether or not the number of input persons is one or more (step S203), and is less than one person, that is, the number of accompanying persons is not input or the input number is “0”. "Is a case where only the user moves alone (in other words, there is no accompanying person to move together as indicated by the same symbol mark 26) (step S203; NO), and the display of the symbol mark The mode is set to the normal display mode (step S204), and the display mode setting operation according to the first embodiment is completed.

  On the other hand, when the number of persons input in the determination in step S203 is one or more (step S203; YES), the accompanying person presence / absence information acquisition unit 18 next has one person (that is, one accompanying person). It is determined whether or not there is (step S205). Accordingly, when the number of persons is one (step S206; YES), the accompanying person presence / absence information acquisition unit 18 sets the display mode of the symbol mark to the overlap display mode (step S206), and the display according to the first example. The mode setting operation ends.

  On the other hand, when the number of persons input in the determination in step S205 is not one (step S206; NO), the accompanying person presence / absence information acquiring unit 18 has two or more accompanying persons and the number confirmed in step S202 is present. If so, the display mode of the symbol mark is set to the continuous display mode (step S207), and the display mode setting operation according to the first embodiment is completed.

  Next, the display operation of the guidance route in the case where the route guidance is actually performed using the display mode set by the setting operation of the symbol mark display mode described with reference to FIG. This will be specifically described with reference to (b). FIG. 6B is a flowchart showing the display operation.

  As shown in FIG. 6B, in the guidance route display operation according to the first embodiment, first, the user operates the operation unit 13 to activate an application relating to route guidance (step S301).

  Next, the system control unit 33 displays information necessary for displaying a guidance route, a symbol mark, and the like (specifically, information indicating a departure place and a destination relating to the movement of the user (see FIG. 7B)) It is determined whether or not the content selected using the selection item 4b illustrated in FIG. 7C has been input (step S302), and if all the necessary information has been input (step S302; YES) However, if there is still uninput information (step S302; NO), the process waits until all necessary information is input by the user (step S303).

  As information necessary for displaying the guidance route, at least a departure place and a destination need to be input. For the departure place, for example, the position information acquisition unit 16 using the GPS positioning unit 14 is used. The position information related to the current position acquired by the above may be used. In this case, if the current position information indicating the current position can be acquired by the position information acquisition unit 16, the setting screen 3 is displayed on the display screen of the display unit 12 as illustrated in FIG. 7B, for example. In this state, the fact that the current position has been acquired is displayed in the “departure place” field.

  Next, as the operation of step S304, the system control unit 33 inputs all necessary information on the setting screen 3 and when the user operates the route search button 3a in the setting screen 3, the server SV Information indicating the display mode set in the symbol mark display mode setting operation (see FIG. 6 (a)) together with necessary information (the presence / absence of a companion and information on the number of persons accompanying the companion) Including) is transmitted to the server SV (step S304).

  Thereby, the route information generation unit 37 in the system control unit 36 of the server SV next searches the map data M1 in the storage unit 11 for route information corresponding to the guide route.

  In addition to this, the symbol mark generation unit 34 of the system control unit 36 displays the symbol mark 25 on the display unit 12 of the mobile phone MP (that is, when the display mode set in the mobile phone MP is the normal display mode). ) Searches the storage unit 11 for the corresponding symbol mark data M2. When the same symbol mark 26 is displayed on the display unit 12 of the mobile phone MP (that is, when the display mode set in the mobile phone MP is either the overlap display mode or the continuous display mode), the corresponding symbol mark is displayed. The symbol mark data M2 necessary for generating data is searched in the storage unit 11 and symbol mark data corresponding to the same symbol mark 26 is generated. Thereafter, the system control unit 36 carries either the symbol mark data M2 corresponding to the symbol mark 25 or the symbol mark data corresponding to the same symbol mark 26 and the search result of the route information via the communication unit 35. Send to phone MP.

  As a result, the route information acquisition unit 17 of the mobile phone MP obtains the route information searched by the system control unit 36 of the server SV (that is, route information indicating the guide route that the user is scheduled to travel) via the network NW and the communication unit 31. (Step S305). The display control unit 20 displays the acquired route information on the display screen of the display unit 12 as the route search result screen 4 illustrated in FIG. Here, the route search result screen 4 displays one or a plurality of route search results 4a. At this time, since a plurality of search results are usually displayed as the route search result 4a, the user operates the operation unit 13 to select route information as one route search result.

  In the route search result screen 4, as shown in FIG. 7C, a route display selection for selecting a guide route display using a map and a guide route display using text (characters). Button 4c is included. Accordingly, when the user selects either one of the route display selection buttons 4c, the system control unit 15 uses the selected display mode (either display using a map or display using text) to display the symbol mark. 25 or the same symbol mark 26 and the guide route are displayed on the display unit 12 (see step S306 described later).

  In parallel with these, the symbol mark acquisition unit 19 of the mobile phone MP switches to the display mode (that is, one of the normal display mode, the overlap display mode, or the continuous display mode) set by the operation for setting the display mode of the symbol mark. Correspondingly, either the symbol mark data M2 corresponding to the symbol mark 25 transmitted from the server SV or the symbol mark data corresponding to the same symbol mark 26 is acquired (step S305).

  As a display form of the symbol mark according to the first embodiment, as described above, the display of the symbol mark 25 indicating the current position of the user when moving only by the user (that is, when there is no accompanying person), When there is a companion, it is possible to display the same symbol mark 26 indicating “to move together” based on the current position of the user, so the display control unit 20 and the map display control unit 32 displays the symbol mark 25 or the same symbol mark 26 on the display unit 12 together with the guide route corresponding to the acquired route information and the map including the same using the acquired symbol mark data (step S306). The guide route display operation according to the first embodiment is terminated.

  Thereafter, the display control unit 20 and the map display control unit 32 move the display position of the symbol mark 25 or the same symbol mark 26 on the display unit 12 according to the movement of the user.

  More specifically, the display control unit 20 selects the route display selection button 4c (see FIG. 7C) for selecting the display of the guide route using the map, and the display mode is the overlap mode or the continuous mode. 8A, as illustrated in FIG. 8A, the map 6 around the destination (G) from the departure point (S) and the guide route 5 to guide the user are the same as described above. Symbol mark 26 (same symbol mark corresponding to symbol mark data consisting of symbol mark data M2 corresponding to symbol mark 25 for displaying the user himself and symbol mark data M2 corresponding to symbol mark 25a for displaying the accompanying person 26) is displayed on the display screen of the display unit 12. When the current position information of the user is updated according to the movement of the user, the display position of the same symbol mark 26 displayed on the display screen is moved according to the movement of the user. At this time, the guide route 5 is displayed in a distinguishable manner with respect to other roads and the like.

  On the other hand, when the route display selection button 4c (see FIG. 7C) for selecting the display of the guidance route by text is selected and the display mode is either the overlap mode or the continuous mode. As shown in FIG. 8B, the guide route 7 using only text without using the map 6 and the same symbol mark 26 are displayed on the display screen. When the current position information of the user is updated according to the movement of the user, the display position of the same symbol mark 26 displayed on the display screen according to the movement of the user is changed to the updated current position. Move to the vicinity of the display position of the text corresponding to the information.

  On the other hand, when the display mode is the normal mode, it is known that the user does not have a companion (see step S203 in FIG. 6 (a); NO). Only the symbol mark 25 indicating the current position of the user himself / herself is displayed on the display screen of the display unit 12 according to the display mode selected using the selection button 4c.

  More specifically, when the display of the guidance route using the map is selected using the route display selection button 4c, the display control unit 20 displays the map 6 around the destination (G) from the departure point (S). And a guide route 5 to guide the user and a symbol mark 25 that moves according to the movement state of the user are displayed on the display screen of the display unit 12 (see FIG. 8A), and then the first In the embodiment, the guide route display operation ends. In addition, when the display of the guidance route by text is selected using the route display selection button 4c, instead of the map 6, the guidance route 7 using only the text and the symbol that moves according to the movement state of the user The mark 25 is displayed on the display screen of the display unit 12 (see FIG. 8B), and then the guide route display operation is terminated in the first embodiment.

  In the case of the first embodiment, it is preferable that the turtles constituting the symbol mark 25 or the same symbol mark 26 have a mode as if the turtle is walking (see Patent Document 1). Further, when the user stops, for example, if an animation is displayed in which the turtle pulls both hands and feet and the head into the shell, the user can still be interested.

(II) Second Embodiment Next, the operation of the guidance route display system according to the second embodiment will be described with reference to FIG. FIG. 9 is a flowchart showing the setting operation of the symbol mark display mode among the operations of the guidance route display system according to the second embodiment. The hardware configuration of the guidance route display system including the mobile phone according to the second embodiment is basically the same as the hardware configuration of the guidance route display system SS according to the first embodiment. In the following description, common members will be described using the same member numbers.

  In the first embodiment described above, the cellular phone MP included in the guidance route display system SS is only the one carried by the user. On the other hand, in the second embodiment described below, in addition to the mobile phone MP carried by the user, a companion who moves with the user also carries a mobile phone (not shown). The mobile phone MP carried by the user and the accompanying mobile phone can transmit and receive data to and from each other via the communication unit 31. This data transmission and reception is performed, for example, by a predetermined short-range wireless communication system. It is executed using

  In the following description of the second embodiment, the mobile phone carried by the user is referred to as a mobile phone MP, and there are two or more other mobile phones carried by another person (accompanying person). In all cases, this is collectively referred to as “accompanied mobile phone”. At this time, the mobile phone of the accompanying person is a mobile phone that is carried by a person who is in a predetermined relationship with the user (for example, the above-mentioned family relationship or friend relationship, which becomes a companion according to the embodiment when moving). Thus, for example, it is possible to register in the mobile phone MP using terminal ID information or the like that mutually identifies each of the accompanying mobile phones from other mobile phones.

  Further, in the second embodiment, as the display mode of the symbol mark according to the second embodiment, the same three display modes as the display mode according to the first embodiment, the normal display mode, the overlap display mode, and the continuous display mode are defined. ing. In the guidance route display operation according to the second embodiment, the mobile phone of the accompanying person who moves together with the user is previously registered in the mobile phone MP of the user, and the registered mobile phone of the accompanying person is One display mode is selected from the three display modes and executed according to the number of connected devices using the short-range communication method. When no accompanying mobile phone is registered in the mobile phone MP, the user operates the operation unit 13 to input the number of accompanying users who are traveling with the user (FIG. 3B). And (c)), a display mode corresponding to the number of persons is set.

  As shown in FIG. 9, in the display mode setting operation according to the second embodiment, first, the user operates the operation unit 13 of the mobile phone MP as in the case of the first embodiment to execute the walking navigation application. Start (step S401).

  Next, the accompanying person presence / absence information acquiring unit 18 of the mobile phone MP determines whether or not the terminal ID information of the accompanying mobile phone has been registered (step S402). Thereby, when any terminal ID information has been registered (step S402; YES), the process proceeds to the operation of step S404 described later. On the other hand, when no terminal ID information is registered (step S402; NO), the display mode setting operation similar to the display mode setting operation according to the first embodiment described with reference to steps S202 to S207 in FIG. The same confirmation operation and display mode setting operation are performed (step S403), and the display mode setting operation according to the second embodiment is terminated.

  If any of the terminal ID information has already been registered in the confirmation in step S402, the accompanying person presence / absence information acquiring unit 18 then selects the short distance between the accompanying person's mobile phone according to the registered terminal ID information. Communication by the communication method is attempted, and it is determined whether or not connection with the accompanying mobile phone is possible (step S404). As a result, when connection with any of the accompanying mobile phones is impossible (step S404; NO), the accompanying presence / absence information acquiring unit 18 determines that the accompanying mobile phone of the accompanying ID related to the terminal ID information that could not be connected. Attempts to reconnect to the terminal, and then proceeds to step S402 (steps S405, S405; NO). On the other hand, if connection is not possible even after two attempts in the operation of step S405 (step S405; YES), the accompanying person presence / absence information acquisition unit 18 does not have a accompanying person's mobile phone (in other words, The display mode in the mobile phone MP is set to the normal display mode (step S406), and the display mode according to the second embodiment is set. End the operation.

  On the other hand, in the confirmation in step S404, if connection with any of the accompanying mobile phones is possible (step S404; YES), the accompanying person presence / absence information acquiring unit 18 next allows the accompanying person who was able to connect. The number of mobile phones is confirmed (step S407), and it is determined whether or not the number of connectable phones is one (step S408). Accordingly, the accompanying person presence / absence information acquiring unit 18 considers that the accompanying person is only one person when the connection with the accompanying accompanying person's mobile phone is possible (step S408; YES), and the mobile phone MP. Is set to the overlap display mode (see FIGS. 4A, 4C, or 4D) (step S409), and the display mode setting operation according to the second embodiment is completed.

  On the other hand, if it is possible to connect two or more accompanying mobile phones in the confirmation in step S408 (step S408; NO), the accompanying presence / absence information acquisition unit 18 then selects the mobile phone MP. The display mode is set to the continuous display mode (see FIG. 4B) (step S410), and the display mode setting operation according to the second embodiment is completed.

  In the setting operation described with reference to FIG. 9, when a connection is made with a new accompanying mobile phone during the setting operation in step S404, the display mode is changed accordingly as appropriate. It is desirable to configure so as to.

  After the display mode setting operation described with reference to FIG. 9, the same guide route display operation as that in the first embodiment is executed (see FIG. 6B).

  According to the operation of the guidance route display system according to the second embodiment described above, the same symbol mark 26 is displayed for the accompanying person unless the connection with the accompanying person's mobile phone is disconnected. . In other words, when the connection is disconnected, the same symbol mark 26 is changed to the normal symbol mark 25.

(III) Third Example Finally, the operation of the guidance route display system according to the third example will be described with reference to FIG. FIG. 10 is a flowchart showing the setting operation of the symbol mark display mode among the operations of the guidance route display system according to the third embodiment. The hardware configuration of the guidance route display system including the mobile phone according to the third embodiment is basically the same as the hardware configuration of the guidance route display system according to the second embodiment. In the description, common members will be described using the same member numbers.

  In the second embodiment described above, the configuration in which the display mode is switched in the mobile phone MP carried by the user according to the number of accompanying mobile phones that can be connected has been described. In the third embodiment described below, however, In consideration of the distance between the person's mobile phone and the user's mobile phone MP, if the distance is less than or equal to a preset threshold, it is determined that the accompanying person is present and the same symbol mark 26 Is displayed on the display unit 12. Therefore, it is determined that a companion always exists when the distance is equal to or less than the threshold value. Even if the distance changes within a range equal to or less than the threshold value, the display mode of the same symbol mark 26 itself is It does not change. When the distance is longer than the threshold value, the same symbol mark 26 itself is replaced with a symbol mark 25 (symbol mark 25 indicating the user) which means that no companion exists for the user. .

  Note that the user's mobile phone MP according to the third embodiment can exchange data with another person's mobile phone via the communication unit 31. Furthermore, the mobile phone of the other person is a mobile phone that is carried by a person who has a predetermined relationship with the user (for example, a friend, a person related to the company, or a family member). Each of the other person's mobile phones can be registered in the mobile phone MP using terminal ID information or the like that is mutually identified from the mobile phone of a person other than the predetermined person (third party). Has been.

  Furthermore, in the third embodiment, as the display mode according to the third embodiment, the same three display modes as the display mode according to the first or second embodiment are defined: normal display mode, overlap display mode, and continuous display mode. Has been.

  As shown in FIG. 10, in the display mode setting operation according to the third embodiment, first, the user operates the operation unit 13 of the mobile phone MP in the same manner as in the first embodiment to activate the walking navigation application. Start (step S501).

  Next, the system control unit 33 determines whether or not its current position has been measured using the GPS positioning unit 14 (step S502). If the positioning has been completed (step S502; YES), a step to be described later The process proceeds to S504. On the other hand, when the current position is not yet measured (step S502; NO), the system control unit 33 uses the GPS positioning unit 14 to measure the current position, and obtains the current position information corresponding thereto as the position information acquisition unit 16. (Step S503), the process proceeds to Step S502.

  Next, the accompanying person presence / absence information acquisition unit 18 determines whether or not the other person's current position information has been acquired from the other party's mobile phone related to the registered terminal ID information via the communication unit 31. (Step S504). As a result, if the current position information is not obtained from any of the other person's mobile phones (for example, the current position information is displayed even if a predetermined time elapses after the walking navigation application is activated (see step S501)). If not acquired (step S504; NO), the accompanying person presence / absence information acquiring unit 18 determines that no accompanying person exists in the user (step S505), and proceeds to an operation of step S507 described later.

  On the other hand, in the confirmation in step S504, when the current position information is acquired from all or any of the other person's mobile phones (step S504; YES), the accompanying person presence / absence information acquisition unit 18 next acquires the acquired current position. The distance between the current position indicated by the information and the current position of the user's mobile phone MP is close to the other person and the user (in other words, the other person is the It is checked whether or not the distance that can be regarded as “accompanied” is equal to or less than a threshold set in advance (step S506).

  Here, the acquired current position information indicating the current position of the mobile phone of the other person is, for example, another person who is uniquely positioned by the GPS positioning unit 14 provided in each of the other person's mobile phones. This is current position information indicating the current position of each of the mobile phones. In the operation of step S502 or S503, for example, the mobile phone MP sends a request for acquiring current location information to the mobile phone of another person using the registered terminal ID information via the communication unit 31, for example. It is preferable that the current position information is acquired.

  Then, when there is no other person's mobile phone whose distance is equal to or less than the threshold (step S506; NO), the accompanying person presence / absence information acquiring unit 18 does not have an accompanying person in the vicinity (in other words, In this case, it is assumed that there is no accompanying person to be indicated by the same symbol mark 26), and the display mode in the mobile phone MP is set to the normal display mode (step S507), and the display mode according to the third embodiment is set. End the operation.

  Even when it is determined that no accompanying person is present in the operation in step S505, the display mode in the mobile phone MP is similarly set to the normal display mode (step S507), and the display mode according to the third embodiment. End the setting operation.

  On the other hand, in the confirmation in step S506, when there is a mobile phone of another person whose distance is equal to or smaller than the threshold (step S506; YES), the accompanying person presence / absence information acquisition unit 18 next selects another person whose distance is equal to or smaller than the threshold. The number of the mobile phone of the person is confirmed (step S508). As a result, if the number is one (step S508; YES), the accompanying person presence / absence information acquiring unit 18 considers that there is only one “accompanying person” according to the embodiment, and sets the display mode in the mobile phone MP. The overlap display mode (see FIGS. 4A, 4C, or 4D) is set (step S509), and the display mode setting operation according to the third embodiment is completed.

  On the other hand, in the confirmation in step S508, when the number of other person's mobile phones is two or more, the accompanying person presence / absence information acquisition unit 18 changes the display mode of the mobile phone MP to the above-described continuous display mode (FIG. )) (Step S510), and the display mode setting operation according to the third embodiment is terminated.

  After the display mode setting operation described with reference to FIG. 10, the same guide route display operation as that in the first embodiment is executed (see FIG. 6B). In this case, the presence of the other person's mobile phone whose distance is equal to or smaller than the threshold in step S506 is displayed as the same symbol mark 26 including the symbol mark 25 indicating the user of the mobile phone MP, and the user moves. Will move. That is, the other person is a companion who moves with the user, and the current position indicated by the current position information acquired from the other person's mobile phone and the current position measured by the user's mobile phone MP. Display of the same symbol mark 26 as the current position information of the user's mobile phone MP is updated regardless of whether or not the current position information of the other person's mobile phone is updated. Move the position inseparably.

  Incidentally, the distance from the current position of the other person's mobile phone that is equal to or less than the above threshold is the same as the above-mentioned threshold value as the user's current position information is updated or the current position information of another mobile phone is acquired. When the distance exceeds the distance, the form is changed from the display of the same symbol mark 26 to the display of the symbol mark 25.

  In the second and third embodiments described above, based on the number of mobile phones of the accompanying persons (in the case of the second embodiment) or the positions of other people's mobile phones (in the case of the third embodiment). When the same symbol mark 26 is displayed on the display unit 12 of the user's mobile phone MP, the symbol mark data corresponding to the symbol mark 25a indicating the accompanying person is obtained from the symbol mark data M2 stored in the server SV. Instead, it is obtained from the corresponding mobile phone of the accompanying person (or another person), and using this, symbol mark data corresponding to the same symbol mark 26 is generated and displayed on the display unit 12 in the mobile phone MP. It can also be configured. In this case, it is possible to use various symbol mark data stored in the mobile phone of the accompanying person (or another person) instead of the existing symbol mark data M2 in the server SV. The same symbol mark 26 in a rich manner can be displayed on the display unit 12.

  As described above, according to the operation of the display device S according to the embodiment and the guidance route display system SS according to each example, the same symbol mark 26 is displayed on the display unit 12 when a companion is present in the user. And the display position of the same symbol mark 26 is also moved in accordance with the movement of the user, so that it can be easily recognized that the user is present and is moving together.

  Therefore, the convenience when the user is accompanied by the user can be improved.

  Further, a symbol mark corresponding to the same symbol mark 26 including the symbol mark data M2 corresponding to the companion mark 25a (see FIG. 4) in the display mode corresponding to the acquired number of people is generated / displayed in correspondence with the current position of the user. Therefore, it is possible for any number of people to easily grasp how many people are traveling when there are many accompanying persons.

  Further, for example, when there is only one companion, symbol mark data (see FIG. 4A or FIG. 4D) in which the user mark 25 and the companion mark 25a are superimposed is a symbol mark corresponding to the same symbol mark 26. In the case of acquiring as data, for example, the same symbol mark 26 relating to a user who is in a parent-child relationship and a companion can be displayed in a manner suitable for the relationship.

  Furthermore, for example, when there is only one companion, symbol mark data (see FIG. 4B or FIG. 4C) in which the user mark 25 and the companion mark 25a are adjacent to each other is used as the same symbol mark 26. When acquiring as corresponding symbol mark data, for example, the same symbol mark 26 relating to a friend and a companion can be displayed in a mode suitable for the relationship.

  When the guide route 5 to guide the user and the map 6 including the guide route 5 are displayed on the display unit 12 together with the same symbol mark 26, the guide route on which the user moves is displayed on the accompanying person. It can be easily recognized along with the presence or absence.

  Furthermore, the user mark 25 and the accompanying person mark 25a are each composed of an animal character, and the display form of the user mark 25 and the accompanying person mark 25a is changed according to the moving state of the user, so that the visual It is possible to enhance the effect and provide guidance from the start point (user's current position) to the destination while always being interested.

  Furthermore, according to the operation of the guidance route display system according to each embodiment, since route information is acquired from the server SV, while reducing the processing burden in the mobile phone MP where reduction in size and weight and low power consumption are desired, The same symbol mark 26 and the guide route 5 can be displayed on the display unit 12.

  Further, according to the operation of the guidance route display system according to the second and third embodiments, the number of connected mobile phones of the accompanying person and the mobile phone of another person whose distance to the mobile phone is below a threshold value. Since the display mode of the symbol mark 25 or the same symbol mark 26 is automatically set according to the number of persons (in other words, the number of accompanying persons), it is not necessary for the user to set the display mode in particular, thereby saving the effort. Can do.

  In each of the above-described embodiments, the overlap mode is set when there is only one companion, and the continuous mode is set when there are two or more companions. When two or more persons are moving together, symbol marks 25a (preferably different symbol marks 25a) indicating each of the accompanying persons are overlapped with each other, and this is further overlapped with the symbol mark 25a indicating the user. An overlapping mode for the same symbol mark 26 having the above-described aspect may be set. On the other hand, even when there is only one companion, the same symbol mark 26 having a mode in which the symbol mark 25 indicating the user and the symbol mark 25a indicating one companion are adjacent to each other (see, for example, FIG. 4B). A continuous mode may be set. That is, by inputting information indicating the relationship with the user, even when there is only one accompanying person, either the overlap mode or the continuous mode may be automatically set in consideration of the relationship. .

  Further, in each of the above-described embodiments, the symbol mark data corresponding to the same symbol mark 26 generated in the server SV is transmitted to the mobile phone MP, but in addition to this, the symbol corresponding to the same symbol mark 26 is used. Each symbol mark data M2 (that is, the symbol mark data M2 corresponding to the symbol mark 25 indicating the user and the symbol mark data M2 corresponding to the symbol mark 25a indicating the accompanying person) constituting the mark data itself is received from the server SV. It is also possible to transmit to the mobile phone MP and use these to generate symbol mark data corresponding to the same symbol mark 26 in the mobile phone MP.

  In addition, in the above-described embodiment and each example, if the user can select the display mode of other types or symbols of other animals, it is possible to set the display screen so that the user can easily see the display screen. .

  In addition, when the guide route 7 is displayed in the manner described with reference to FIG. 8B, the transfer of the map data M1 is basically unnecessary, so that the communication fee between the mobile phone MP and the server SV is not charged. As a result, the communication charge can be reduced and the communication time can be shortened.

  Moreover, in the said embodiment and Example, although this application was demonstrated applying to the display apparatus S (mobile telephone MP) which displays a present position on the map 6, in addition to this, the communication navigation apparatus for pedestrians, a car navigation system, etc. It is also possible to apply the present application to an apparatus. Furthermore, for example, operations in other portable terminal devices such as PDA (Personal Digital Assistant) may be applied, or the present application is not limited to these portable terminal devices and can be applied to general personal computers. It is.

  Further, in each of the above embodiments, the server SV stores the map data M1 and transmits the map data M1 to the mobile phone P in response to a request from the mobile phone MP. The operation may be performed with all the data M1 stored. In this case, the server SV is not essential due to the system configuration.

  Furthermore, the programs corresponding to the flowcharts shown in FIG. 2, FIG. 6, FIG. 9 and FIG. 10 are recorded on a recording medium such as a flexible disk or a hard disk, or acquired and recorded via a network such as the Internet. If these are read and executed by a general-purpose microcomputer or the like, the microcomputer can be used as the system control unit 15 according to the embodiment or the system control unit 33 according to each example.
