That is, a message requesting input of user authentication information such as a user ID is output to the display unit 150 of the mobile terminal 100. Therefore, when the user inputs user authentication information such as a user ID from the key input unit 160, the information processing unit 110 inputs the user authentication information (step S12) and transmits the input user authentication information to the server device 400. (Step S13).

  Next, the information processing unit 410 of the server device 400 receives the user authentication information transmitted by the mobile terminal 100 as the process of the user authentication processing unit 412 (step S14), and performs user authentication based on the received user authentication information. (Step S15). In step 15, a user ID is used as user authentication information. That is, it is determined whether or not the same user ID as the received user ID has already been registered in the user master file 4171 of the visitor DB 417, and if the same user ID as the received user ID is registered, the authentication is successful. If it is not registered, authentication fails. Next, the information processing unit 410 transmits the authentication success / failure information of the user authentication in step S15 to the mobile terminal 100 (step S16).

  Subsequently, the information processing unit 110 of the mobile terminal 100 receives the authentication success / failure information transmitted by the server device 400 (step S17), and when the received authentication success / failure information indicates successful authentication (step S18). Yes), the main menu display screen as shown in FIG. 7 is displayed on the display unit 150 (step S19). If the received authentication success / failure information indicates an authentication failure (No in step S18), the execution of the login processing unit 111 is terminated.

  FIG. 7 is a diagram illustrating an example of a main menu display screen displayed on the display unit of the mobile terminal according to the present embodiment. As shown in FIG. 7, on the main menu display screen G01, buttons for “group setting”, “map display setting”, “position private setting”, and “meeting place setting” are displayed as sub menu display instruction buttons. In addition, an “application end” button for ending the application related to the group member position information sharing system is displayed. That is, when the main menu display screen G01 is displayed, the user can use the group member position information sharing system according to the present embodiment.

  Therefore, when the user presses each submenu display instruction button on the main menu display screen G01, submenu display screens G02 to G05 as shown in FIGS. 8 to 11 are displayed according to the submenu. . Here, FIG. 8 is a diagram showing an example of a group setting submenu display screen, FIG. 9 is a diagram showing an example of a map display setting submenu display screen, and FIG. 10 is a location secret setting subscreen. FIG. 11 is a diagram illustrating an example of a menu display screen, and FIG. 11 is a diagram illustrating an example of a submenu display screen for setting a meeting place.

(Group setting process)
In FIG. 7, when the user presses the “group setting” button, a group setting submenu screen G02 as shown in FIG. 8 is displayed. In the group setting submenu screen G02 of FIG. 8, buttons “Create Group”, “Join Group”, “Leave Group”, “Delete Group”, and “Return” are displayed. Hereinafter, operations of the mobile terminal 100 and the server device 400 when the user presses each button displayed on the group setting submenu screen G02 will be described in detail with reference to FIG. 12 and FIG.

  Here, FIG. 12 is a diagram illustrating a flow of group creation processing in the group setting processing unit of the mobile terminal according to the present embodiment and a flow of group creation processing in the group setting processing unit of the server device. FIG. 13 is a diagram showing a flow of group participation processing in the group setting processing unit of the mobile terminal according to the present embodiment and a flow of group participation processing in the group setting processing unit of the server device.

  In FIG. 8, when the user presses the “Create Group” button on the group setting submenu screen G02, as shown in FIG. 12, the information processing unit 110 of the mobile terminal 100 attaches his / her user ID to the group creation command. Is transmitted to the server device 400 (step S21).

  When receiving the group creation command (step S22), the information processing unit 410 of the server device 400 refers to the user master file 4171 to determine whether or not the user ID attached to the group creation command is a registered user. Determination is made (step S23). As a result of the determination, if the user is a registered user (Yes in step S23), it is further determined whether or not a group can be created (step S24). Here, when a group has already been created with the group temporary ID of the registered user, or when a predetermined number or more of groups have been created as a whole system, the group cannot be created.

  If it is determined in step S24 that a group can be created (Yes in step S24), the information processing unit 410 issues a group ID and password, and the issued group ID and password information is stored in the visitor DB 417. A new group is registered in the group master file 4172 (see FIG. 5) (step S25).

  It is assumed that the group ID issued at this time is a group temporary ID stored in the user master file 4171 in association with the user ID of the user of the mobile terminal 100 that has transmitted the group creation command. Then, a new record of the group master file 4172 is created with the issued group ID and password. However, at this time, the fields of the participant user ID and the location private information are blank.

  Next, the information processing unit 410 transmits a group creation completion notification notifying that a new group has been registered to the transmission-source portable terminal 100 that has transmitted the group creation command first (step S26). The mobile terminal 100 that has received the transmission receives the group creation completion notification (step S27), and displays a group creation completion message on the display unit 150 (step S28).

  On the other hand, if it is determined in step S23 that the user is not a registered user (No in step S23), or if it is determined in step S24 that a group cannot be created (No in step S24), the information processing unit 410 A group creation refusal notification notifying that group creation has been rejected is transmitted to the mobile terminal 100 that has transmitted the group creation command first (step S31). The mobile terminal 100 that has received the transmission receives the group creation rejection notification (step S32), and displays a group creation rejection message on the display unit 150 (step S33).

  As described above, when one of the group members presses the “create group” button on the group setting submenu screen G02 (see FIG. 8), the group temporary ID issued to the group member is used as the group ID. Is created. Then, next, each group member applies for participation to the created group. At this time, the user who requests to join the group presses the “join group” button on the group setting submenu screen G02. Then, in the mobile terminal 100, the group participation process shown in FIG. 13 is started.

  First, the information processing unit 110 of the mobile terminal 100 displays a message prompting the display unit 150 to input a group ID and password of a group that the user intends to join. Then, the information processing unit 110 inputs the group ID and password that the user keys in from the key input unit 160 (step S40), attaches the input group ID and password, and his / her user ID to the group participation command. Is transmitted to the server device 400 (step S41).

  When receiving the group participation command (step S42), the information processing unit 410 of the server device 400 refers to the user master file 4171 to determine whether or not the user ID attached to the group creation command is a registered user. Determination is made (step S43). As a result of the determination, if the user is a registered user (Yes in step S43), it is further determined by referring to the group master file 4172 whether the group ID attached to the group creation command is a registered group ( Step S44).

  As a result of the determination, if it is a registered group, the information processing unit 410 performs a group participation acceptance process (step S45). That is, the user who transmitted the group participation command is added to the record of the group for which the participation of the group master file 4172 is requested. In other words, a set of participant user ID and location private information fields are added to the record of the group ID (group ID attached to the group participation command), and the participant user ID field includes the user ID. (User ID attached to the group participation command) is stored. Further, the group ID is stored in the participation group field in the record of the user ID of the user master file 4171.

  Then, the information processing unit 410 transmits a group participation acceptance notification notifying that the participation in the group has been accepted, to the transmission-source mobile terminal 100 that has transmitted the group participation command (step S46). The portable terminal 100 receives the group participation acceptance notification (step S47), and displays the group participation acceptance message on the display unit 150 (step S48).

  On the other hand, if it is determined in step S43 that the user is not a registered user (No in step S43), or if it is determined in step S44 that the user is not a registered group (No in step S44), the information processing unit 410 first A group participation refusal notification notifying that the group participation has been rejected is transmitted to the transmitting mobile terminal 100 that has transmitted the group participation command (step S51). The mobile terminal 100 that has received the transmission receives the group participation rejection notification (step S52), and displays a group participation rejection message on the display unit 150 (step S53).

  As described above, the user can join the already registered group. Although not shown in FIG. 13, when the participation of a new user is accepted (step S45), the information processing unit 410 of the server device 400 displays the mobile terminals of the users already participating in the group. A message notifying that a new user has participated may be transmitted to 100. In this case, since the mobile terminal 100 that has received the message displays a message notifying the participation of the new user on the display unit 150, the already participating user can know the participation of the new user. In the portable terminal 100, the group ID in which the user participates and the user IDs of the users participating in the group with the group ID are stored in the group information table 118.

  Next, on the group setting submenu screen G02 of FIG. 8, when the user presses the “leave group” button, the mobile terminal 100 transmits a group leave command with the user ID and participation group ID to the server device 400. To do. When the server device 400 receives the group leaving command, the server device 400 deletes the data of the participation group ID from the participation group ID field of the record of the user ID in the user master file 4171 and records the group ID in the group master file 4172. The participant user ID field corresponding to the user and the location private information field attached thereto are deleted. Furthermore, the server device 400 transmits information about the user who has left the group to the mobile terminals 100 belonging to the group. The mobile terminal 100 receives information about a user who has left the group, and displays the received information on the display unit 150.

  In addition, when the user presses the “group delete” button on the group setting submenu screen G02 of FIG. 8, the mobile terminal 100 transmits a group delete command with the user ID and the participating group ID to the server device 400. Upon receiving the group deletion command, the server apparatus 400 extracts the user ID of the user participating in the group from the group ID record in the group master file 4172, and joins the user ID record in the user master file 4171. Delete the group ID from the group ID field. Then, the record of the group ID in the group master file 4172 is deleted.

  In the above embodiment, the process of creating a group and joining the group is performed based on an operation from the mobile terminal 100. However, the group member information is gathered together at the entrance of the theme park 600, and the input / output terminal. You may perform by the batch process input from 440. FIG. However, even if it does so, it is better to be able to perform creation of a group and participation of a group based on operation from the portable terminal 100 like this embodiment. By performing the process of creating a group and joining a group based on an operation from the mobile terminal 100, the user can flexibly create a group and join the group. For example, after entering the theme park 600, the group can be rearranged or the members can be changed.

(Positioning & map display processing)
FIG. 14 is a diagram illustrating a process flow in the position measurement & map display processing unit of the mobile terminal according to the present embodiment and a process flow in the position information registration & acquisition processing unit of the server apparatus. It is assumed that the processing described in FIG. 14 is started at a predetermined time interval (for example, every 30 seconds).

  In FIG. 14, the portable terminal 100 measures the position by the GPS radio wave receiver 130 (step S61), and transmits the position information obtained by the positioning to the server device 400 (step S62). When transmitting the position information, a user ID is attached to the position information.

  When the information processing unit 410 of the server device 400 receives the position information (step S63), the information processing unit 410 refers to the user master file 4171 to determine whether or not the user ID attached to the position information is a registered user. (Step S64). As a result of the determination, if the user is a registered user (Yes in step S64), the received position information is registered in the user master file 4171 (step S65). That is, the received position information is stored in the position information field of the record of the user ID in the user master file 4171.

  Next, the information processing unit 410 acquires the participation group of the user from the user master file 4171 (step S66). Then, with reference to the group master file 4172, the user ID and position information of the participating members of the group (the group with the group ID acquired in step S66) are acquired (step S67). Then, the user ID and position information of the participating members of the group are transmitted to the mobile terminal 100 (step S68).

  If it is determined in step S64 that the user is not a registered user (No in step S64), the information processing unit 410 ends the process without executing the processes in steps S65 to S68.

  The mobile terminal 100 receives the user ID and position information of the participating members of the group transmitted by the server device 400 (step S69). When the mobile terminal 100 is in the map display mode (Yes in step S70), A map as shown in FIG. 15 is displayed in accordance with the map display mode setting information described separately (step S71). If the mobile terminal 100 is not in the map display mode (No in step S70), the process ends without displaying the map.

  FIG. 15 is a diagram showing an example of a map display screen displaying member positions in the mobile terminal according to the present embodiment. As shown in FIG. 15, an icon 701 (the center of the map) indicating the position of the user and an icon 702 indicating the positions of the participating members are displayed on the map on the display screen G11. Beside the icon 702 indicating the position of the participating member, memo information 703 displaying the name of the member, information on the distance from his / her position, and the like is further displayed. The display screen G11 displays a compass 704 indicating orientation, scale information 705, position information acquisition time information 706, group name 707, menu button 708, and the like.

  The compass 704 may be a compass indicating the north-south direction on the map fixed to the map. The compass 704 receives the output of the direction detection unit 120 (see FIG. 2) and indicates the actual north-south direction. Or both. When the user presses the menu button 708, the main menu display screen G01 shown in FIG. 7 is displayed.

  In the present embodiment, in the basic map display mode, the position of the user who owns the mobile terminal 100 is displayed at the center (self center) of the map, and the positions of all the members are on one screen. Display at scale. At this time, the scale is automatically calculated and set. In the display screen G11 of FIG. 15, the member A (unnamed on the screen, center icon 701) is displayed at the center. In the display screen G12, the member Z (unnamed on the screen) is displayed in the center, and the map area and scale to be displayed are different from those of the display screen G11.

  That is, in such a display mode, in order to display all the members, the scale and area of the displayed map change depending on whether the user's position is near the center of the group or the peripheral portion. In such a case, it may be inconvenient when group members act in cooperation. For example, when members A and Z make a phone call while looking at the screens G11 and G12 displayed on the respective mobile terminals 100, the scale and display area of the map viewed by each member are different. There is no doubt that an unexpected misunderstanding will not occur. Therefore, in this embodiment, a map display setting submenu as shown in FIG. 9 is prepared in order to match the display method of the map among the members.

  In FIG. 9, buttons of “standard display”, “all members maximum display”, and “member center display” are displayed as a map display setting submenu. When the “standard display” button is pressed, the map display mode is a basic map display mode, that is, a map display as shown in FIG. In addition, when the “all members maximum display” button is pressed, a map of the maximum scale that all members can display on one screen is displayed. When this all-maximum display mode is selected, the same map is displayed for any member.

  In addition, in FIG. 9, when the “member center display” button is pressed, a button displaying a member name is further displayed. When a member name is specified by the button, a map displaying the specified member as a center is displayed. Is done. For example, in FIG. 15, when the member A designates that the member Z is the center and displays the map, even if the mobile terminal 100 of the member A is displayed, the same map display as the display screen G12 of the mobile terminal 100 of the member Z is displayed. Done. By doing in this way, the member A and the member Z can see the map displayed similarly.

  Note that the functions related to the map display setting described above are realized by the information processing unit 110 of the mobile terminal 100 executing the map display setting processing unit 113. Further, the map display mode information set in the processing is stored in the mode setting table 117.

Next, the position non-disclosure function will be described with reference to FIGS. 16 and 10. Here, FIG. 16 is a diagram illustrating a map display example for explaining the position-disclosing function in the mobile terminal 100 according to the present embodiment.

  In FIG. 16, a display screen G13 is a display screen of the mobile terminal 100 of the member A, and a display screen G14 is a display screen of the mobile terminal 100 of the member Z. In this case, the member A is not displayed on the display screen G13 of the mobile terminal 100 of the member Z. This is because the member A puts his / her position information in a non-public mode.

  In order for the member to set his / her position information in the non-disclosure mode, the position non-disclosure setting submenu screen G04 shown in FIG. 10 is used. When the user presses the “Private mode” button on the position non-public setting submenu screen G04, the position information of the user is not disclosed to other users. For example, when the member A sets the position information in the non-public mode, the position of the member A is not displayed on the mobile terminal 100 of the member Z as in the display screen G14 of FIG. Further, when the user presses the “return to public mode” button on the position non-public setting submenu screen G04, the original position information public mode is restored.

  In setting the location private mode, a time range for setting the location private mode can be set in advance by pressing a “private time setting” button. Also, by pressing the “Private Area Setting” button, the area to be set in the position private mode can be set. However, in this case, a schematic diagram of the entire theme park 600 is further displayed so that information for designating an area can be input. In addition, although not shown in the drawing, a member may be specified to be in the position non-disclosure mode.

  In the position private function described above, the information processing unit 110 of the mobile terminal 100 executes the position private setting processing unit 115, and the information processing unit 410 of the server device 400 executes the position private setting processing unit 415. It is realized by. That is, when the “Private mode” button is pressed on the display screen G04 (see FIG. 10), the information processing unit 110 of the mobile terminal 100 transmits information to that effect to the server device 400. . The server device 400 receives the notification, and sets the private flag field of the location private information attached to the participant user ID field of the user in the group record of the group master file 4172.

  Similarly, when the time range or area to be set to the position private mode is set by the “private time setting” button or the “private area setting” button on the display screen G04 of the mobile terminal 100, the set private information is set. Time information or private area information is transmitted from the portable terminal 100 to the server device 400. Then, the server device 400 uses the non-disclosure time information or the non-disclosure area information of the location private information attached to the participant user ID field of the user in the group record of the group master file 4172 or Store in private area information.

  Further, when the server apparatus 400 acquires the user IDs of the participating members of the group from the group master file 4172 in the process of the position information registration & acquisition unit 416 (see FIG. 14) (step S67), the position secret information Check the private flag, private time information and private area information. Then, based on the check, when it is determined that the mode is the non-disclosure mode, the user ID of the participating member is not acquired. Then, since the participating member is regarded as not belonging to the group, the location information of the participating member is not transmitted to the mobile terminal 100.

  As described above, the user can make his / her position information private to other members. In addition, it is convenient for such a position non-disclosure function to be used by, for example, a group leader or supervisor composed of children.

On the display screen G05, buttons for “Meeting place search”, “Route display”, and “Return” are displayed. Therefore, when the user further presses the “search for meeting place” button, a meeting place search command is transmitted from the portable terminal 100 to the server device 400.

  Based on the gathering place search command, the server apparatus 400 obtains the center position of the member having the smallest sum of distances from all members, for example, by the least square method. Further, a landmark such as a road position or a building closest to the center position is searched, and a display such as a display screen G15 in FIG. 17 is performed. Here, reference numeral 711 represents the center position of the member, reference numeral 712 represents the road position closest to the center position 711 (actually beside the road), and reference numeral 713 represents the landmark closest to the center position 711.

  Therefore, the user selects from the road position 712 or the landmark 713 closest to the center position 711 as the meeting place. Alternatively, whether the meeting place is a road position or a landmark may be set in advance. In that case, only one of the road position 712 or the landmark 713 closest to the center position 711 is displayed on the display screen G15. Furthermore, as shown in the display screen G16 in FIG. 17, a plurality of landmarks 713 and 714 close to the center position may be displayed to allow the user to determine the meeting place. When the meeting place is determined, the position information of the meeting place is transmitted from the server device 400 to the mobile terminal 100 of each member.
