For example, the control unit 10 transmits the position information acquired by the GPS unit 17 to the center server 2 via the communication unit 11, receives information corresponding to the position from the server 2, and causes the display unit 14 to display the information. In addition, control is performed such that text data input from the input unit 18 and an image captured by the camera unit 12 are transmitted to the server 2 and stored.

  FIG. 3 is a block diagram showing an example of the configuration of the server 2 of the information service center. As illustrated, the server 2 includes a control unit 20, a communication unit 21, an input unit 22, an output unit 23, a storage device 24, a RAM 25, and a database management unit 26.

  The communication unit 21 is connected to the Internet through a dedicated line or the like, and transmits / receives data to / from the communication terminal device 1.

The RAM 25 is used as a work memory when the CPU of the control unit 20 executes a program.

  The database management unit manages data in the map database 27, the position database 28, and the bulletin board database 29.

  The map database 27 stores map data of the service range. When the communication terminal device 1 does not store map data of a certain point, map data corresponding to the communication terminal device 1 is supplied. It is like that.

  For example, as shown in FIG. 8, the location database 28 stores location names of major buildings, regions, stores, and the like in association with each other.

  The bulletin board database 29 stores information written by the user. For example, as shown in FIG. 9, the bulletin board database 29 stores position data related to information, classification data, written data, and additionally written data. It has become.

  The control unit 20 includes a CPU, and performs various processes in cooperation with the communication unit 21, the input unit 22, the output unit 23, the storage device 24, the RAM 25, the database management unit 26, and the like. For example, based on the position information transmitted from the communication terminal device 1, the bulletin board information is searched from the database and transmitted to the communication terminal device 1.

Next, the operation of this system for the communication terminal device 1 having the above-described configuration will be described.
FIG. 4 is a flowchart showing the overall operation of the communication terminal device 1. FIG. 5 is a flowchart showing an operation of the communication terminal device 1 in a new input. FIG. 6 is a flowchart showing the information display operation of the communication terminal device.

  In receiving the bulletin board service, the communication terminal device 1 first detects the position of the communication terminal device 1 by the GPS unit 17 (step A1).

  When the position where the communication terminal device 1 exists is detected, map data corresponding to the position is read from the map database stored in the storage device 15 (step A2). Here, if the corresponding map data is not stored in the storage device 15, the communication terminal device 1 can notify the server 2 of the position and send the necessary map data.

  If the map data is read, it is determined whether the map display mode is 2D or 3D (step A3). In this embodiment, it is assumed that two-dimensional map data and three-dimensional map data are prepared for the map data according to the position. For example, at a position where a large building exists, three-dimensional map data is prepared so that the user can see the state of each floor of the building. If the read map data is planar (2D), a planar map is displayed (step A4). On the other hand, if the read map data is stereoscopic (3D), stereoscopic display is performed (step A5).

  Next, when the user performs a predetermined operation with the map displayed, it is determined whether a new writing instruction or an information display instruction is given (steps A6 and A7).

  When a new input is instructed here (step A6; Yes), a new input process of bulletin board information is performed (step A8).

  This new input process will be described with reference to the flowchart of FIG.

  In the new bulletin board information input process, first, the position is designated by the user (step B1). The designation of the position is performed by designating a point on the map displayed on the display unit 10 with the touch panel 13.

  When the position on the map is designated by the touch panel 13, the classification is designated and input by the user (step B2). Classification is given to indicate what kind of information the written information relates to, and classifications such as "Japanese food", "Western food", "Chinese food", "Accommodation", "Play" are prepared. It shall be. For example, as shown in FIG. 10, when the position on the displayed map is designated, a window screen for newly inputting write information is displayed, and a plurality of classification designation menus are displayed in advance on this window screen. The item is displayed and specified by touching the menu item.

  After the classification is designated, information to be posted on the bulletin board is written by the user using the keyboard of the input unit 18 (step B3). Note that the writing data can be not only text but also image data acquired from the camera unit 12 as writing data.

  When the new writing of the bulletin board information is completed and, for example, the “Register” icon E1 in FIG. 10 is touched, the written information is transmitted to the server 2 together with the position data and the classification data (step B4). The transmitted data is recorded in the server 2 as will be described later.

  On the other hand, in the map display state, when information display is designated instead of writing new bulletin board information (step A7; Yes), information display processing is executed (step A9).

This information display processing will be described with reference to the flowchart of FIG.
In the information display process, first, the position data acquired by the GPS unit 17 is transmitted to the server 2 (step C1).

  Then, the bulletin board position information is transmitted from the server 2 in response to the transmission of the position data, and the bulletin board position information is received (step C2). The bulletin board position information includes position data in which bulletin board information is registered and type data of the information.

  When the bulletin board position information is received, a bulletin board icon corresponding to the information type data is generated, and the bulletin board icon is displayed at the corresponding position on the displayed map (step C3). For example, FIG. 11 shows a state in which a bulletin board icon E3 indicating a plurality of bulletin board information is displayed as a result of the information display processing being executed by operating the “information” icon E2 after the map is displayed.

  Then, it is determined whether the bulletin board icon E3 displayed on the map has been touched by the user (step C4).

  Here, when the user touches one of the bulletin board icons E3 displayed on the map with a pen or the like, this operation is detected, and the position of the touched bulletin board icon is transmitted to the server 2 (step C5).

  When the position data of the touched bulletin board icon is transmitted, the server 2 acquires the content information (write information) of the bulletin board corresponding to the designated bulletin board icon from the bulletin board information database 29 and transmits it. In response to this, the communication terminal device 1 receives the bulletin board content information transmitted from the server 2 (step C6).

  When the bulletin board content information is received, the bulletin board contents of the designated bulletin board icon E3 are processed, for example, in the form of a balloon and displayed on the display unit 14 (step C7). FIG. 12 shows a state in which the corresponding information content is displayed when one bulletin board icon E3 is touched. By this display, the user can know information regarding a store or the like existing in a certain place written by another person.

  When the user thinks that additional writing is to be performed on the displayed information, for example, the “add” icon E4 in FIG. 12 is operated. When an additional write instruction is given by this operation, the communication terminal apparatus 1 determines that an additional write instruction has been given to the displayed bulletin board contents (step C8; Yes), and additional write processing is performed. (Step C10).

  The additional writing process is similar to the above-described new input process. However, since another person has already input the relevant position and type of information, the classification input menu display is displayed from the input window screen of FIG. The removed input screen is displayed, and only processing such as writing of text data is performed. The additionally written data is transmitted to the server 2 (step C11).

  On the other hand, if additional writing is not performed on the content of the displayed bulletin board, it is determined whether the “return” icon E5 has been operated (step C9). If the “return” icon E5 is operated, the displayed information content (balloon information) is deleted (step C12), and the screen returns to the screen on which the bulletin board icon E3 is displayed.

  In the above example, the process of displaying the bulletin board icon E3 on the communication terminal device 1 has been executed after the user operates the “information” icon E2 in step A7, but without waiting for the user's instruction, It may be executed immediately after the map data is read out.

  Next, the operation of the server 2 in this system having the configuration of FIG. 3 will be described.

  FIG. 7 is a flowchart showing the operation of the server. The server 2 executes various processes in accordance with an instruction from the user performed on the communication terminal device 1 or transmitted data.

  When the user operates the information display instruction in the communication terminal device 1, the terminal position data is transmitted from the communication terminal device 1. When the server 2 determines that this terminal position has been received (step D1; Yes), the server 2 searches for bulletin board information based on the position data (step D2). That is, the server 2 searches the bulletin board information database 29 storing the write information as shown in FIG. 9 for information within a certain range with respect to the received terminal position.

  Then, the data indicating the position data and the type is extracted from the searched writing bulletin board information and transmitted to the communication terminal device 1 as the posted version position information (step D3). The communication terminal device 1 displays the bulletin board icon E3 on the map based on the transmitted information.

  When the user touches the bulletin board icon E <b> 3 in the communication terminal device 1, icon position information is transmitted from the communication terminal device 1. When the server 2 determines that this icon position has been received (step D4; Yes), it reads the content of the corresponding bulletin board from the bulletin board information database 29 and outputs it to the communication terminal device 1 (step D5). The communication terminal device 1 displays the contents of the bulletin board in association with the icons based on the transmitted information.

  On the other hand, if it is determined that new write information is transmitted from the communication terminal device 1 (step D6; Yes), the written information, position, and type data are registered in the bulletin board database 29 (step D7). Since the server 2 has the position information database 27, the store name or the like is automatically added to the received writing information, or the location name or the like written by the user is checked. It can also be configured to.

  If it is determined that additional write information has been transmitted from the communication terminal device 1 (step D8; Yes), the additionally written information is additionally registered in the bulletin board database 29 (step D9). After the additional information is registered, the additional information is added to the bulletin board information and provided to the user.

  As described above, according to the present invention, information related to the position is displayed simply by touching an icon on the map. It becomes possible to look for.

  Note that the bulletin board icon may be displayed in a batch of all types, or may be displayed by switching only a specific type of information by a user operation.

  The information output from the server of the present invention can be applied to a wide area security system or the like by interlocking with the push type information distribution system. In other words, for example, if a person who found a suspicious person specifies a position and writes information about what kind of suspicious person he was, the server immediately pushes to people who are close to the written position after the writing is completed. By distributing, it can be useful for crime prevention. Moreover, by displaying the positions in order of time, it becomes possible to clearly display and track the suspicious person's action range.
