In addition, the mobile terminal device 100 includes a position acquisition unit 112 having a GPS function, an IMES function, and the like so that navigation guidance that reflects the current position in real time can be performed. In addition, the mobile terminal device 100 displays a display unit 114 (for example, a liquid crystal display or an organic EL display) that displays a map display screen including various symbols drawn based on route guidance data, map data, and the like received from the route search server 200. Configured display, monitor, etc.), an audio output unit 116 (for example, a speaker) for outputting audio data, and an input unit (not shown) for inputting a route search condition to be transmitted to the route search server 200 (for example, Key input unit, touch panel, keyboard, microphone, etc.). The input / output control interface unit 108 controls the position acquisition unit 112, the display unit 114, the audio output unit 116, the input unit, and the like.

  Here, the position acquisition unit 112 is a position acquisition unit that receives a position information signal transmitted from the position transmission device 500. Here, the position transmitting device 500 is a device that transmits a position information signal related to latitude and longitude, and may be, for example, a GPS device, or indoors using a position information signal having characteristics similar to those of a GPS signal. An IMES device that realizes IMES (Indoor Message System) technology that enables positioning may be used. Further, when the position transmitting device 500 is a GPS device, the position information signal may further include an altitude, and when the position transmitting device 500 is an IMES device, the position information signal may further include hierarchical information. . The IMES technology is a system developed from the framework of the quasi-zenith satellite, which is a positioning satellite system. Further, the position transmission device 500 may be a small transmission device that is arbitrarily installed at various locations on each floor in a building (multi-story building). Here, self-position information (position ID or the like) corresponding to the installation location is allocated to the small transmitter. And if the portable terminal device 100 enters into the communicable range, the portable terminal device 100 receives the self-location information transmitted from the small transmitter as a positional information signal. The communication method at this time may be, for example, various short-range wireless methods such as an RFID (Radio Frequency Identification) tag system and Bluetooth (registered trademark), an infrared communication method, and the like. In the present invention, the control unit 102 can extract position information including latitude and longitude from the position information signal acquired by the position acquisition unit 112. Further, the position acquisition unit 112 may receive the wireless LAN signal and acquire the identification information of the access point.

  The communication control interface unit 104 is an interface connected to a communication device (not shown) such as an antenna or a router connected to a communication line, a telephone line, etc., and between the mobile terminal device 100 and the network 300. It has a function to perform communication control.

The network 300 has a function of connecting the mobile terminal device 100 and an external device such as the route search server 200 to each other, and includes, for example, the Internet, a telephone line network (mobile terminal line network, and general telephone line network). ), Intranet, power line communication (PLC), or the like.

  The control unit 102 also has an internal memory for storing a control program such as an OS (Operating System), a program defining various processing procedures, and necessary data. And the control part 102 performs the information processing for performing various processes by these programs. The control unit 102 functionally conceptually includes a route search condition transmission unit 102a, a route guidance data reception unit 102b, a current position acquisition unit 102c, a hierarchy information acquisition unit 102d, a guidance point setting unit 102e, a guidance point display unit 102f, a voice guidance.

  The route guidance data receiving unit 102b is route guidance data receiving means for receiving route guidance data transmitted from the route search server 200.

  In addition, the current position acquisition unit 102c extracts the position information including the latitude and longitude from the position information signal received from the position transmission device 500 by the position acquisition unit 112, so that the extracted position information is stored in the mobile terminal device 100. Current position acquisition means for acquiring the current position.

  The hierarchy information acquisition unit 102d is a hierarchy information acquisition unit that acquires current position hierarchy information indicating the hierarchy of the current position.

  Here, the hierarchy information acquisition unit 102d may acquire the current position hierarchy information from the position information signal received from the position transmission device 500 by the position acquisition unit 112. As an example, when the position transmission device 500 is a GPS device, the hierarchy information acquisition unit 102d indicates a hierarchy (for example, “outdoor 1F”, “rooftop”, etc.) where the user is present based on the altitude included in the position information signal. You may acquire present position hierarchy information. Further, when the position transmitting device 500 is an IMES device, the hierarchical information acquisition unit 102d determines the hierarchical level (for example, “basement 1F”, “indoor 1F”, “indoors”) based on the hierarchical information included in the positional information signal. 2F "etc.) may be acquired.

  Further, the hierarchy information acquisition unit 102d may acquire a hierarchy corresponding to the map data displayed on the display unit 114 by the map display unit 102h described later as current position hierarchy information. As an example, if the hierarchical information acquisition unit 102d is in a building where the user cannot receive a position information signal from the GPS device, and the IMES device is not installed in the building, the user can input via the input unit. The layer (for example, indoor 2F) corresponding to the map data of the desired layer (for example, indoor 2F) selected and displayed on the display unit 114 may be acquired as the current position layer information.

  Further, the guidance point setting unit 102e receives the route guidance received by the route guidance data receiving unit 102b based on the current position acquired by the current position acquisition unit 102c and the current position hierarchy information acquired by the hierarchy information acquisition unit 102d.

  The guidance point display unit 102f is a guidance point display unit that displays the guidance points set by the guidance point setting unit 102e on the display unit 114 in distinction from the guidance points of other display hierarchy information. Here, the guide point display unit 102f may display the guide points set by the guide point setting unit 102e and may not display the guide points of other display hierarchy information. Moreover, the guidance point display part 102f may change the display mode of the guidance point set by the guidance point setting part 102e, and the guidance point of other display hierarchy information.

The guidance point (outdoor 1F etc.) guidance point (the guidance point to be displayed) and the guidance point of other display hierarchy information (for example, underground 1F etc.) where there is no user are displayed separately.

  As an example, as shown in FIGS. 3 and 4, the guidance point display unit 102 f adjusts the transmittance (for example, 1% to 100%, etc.) of the guidance points of other display hierarchy information from the current position. You may distinguish and display from the guidance point of the same display hierarchy information as the guidance point displayed next. For example, when the transmittance is set to 100% as shown in FIG. 3, the guide points of the other display hierarchy information are displayed as deleted, and the transmittance is set to 50% as shown in FIG. When set, the information is displayed lighter than the guidance point of the same display hierarchy information as the guidance point displayed next from the current position. Further, as shown in FIG. 5, the guidance point display unit 102f changes the size (for example, large size, medium size, small size, etc.) of the guidance point of the other display hierarchy information from the current position to the next. The guidance points displayed may be displayed separately from the guidance points having the same display hierarchy information. Although not shown, the guide point display unit 102f distinguishes from the guide points of the other display hierarchy information by blinking and displaying only the guide points of the same display hierarchy information as the next guide point displayed from the current position. It may be displayed. In addition, the guidance point display unit 102f highlights only the guidance points having the same display hierarchy information as the next guidance point displayed from the current position (for example, color change, font change, etc.), thereby displaying another display. You may display separately from the guidance point of hierarchy information.

  Returning to FIG. 2, when the current position is located in the vicinity of the guidance point set by the guidance point setting unit 102e, the voice guidance output unit 102g sends voice data corresponding to the guidance point via the voice output unit 116. This is voice guidance output means for performing voice guidance by outputting.

Here, the map display unit 102 h of the mobile terminal device 100 may display the map data of the hierarchy selected by the user via the input unit transmitted from the route search server 200 on the display unit 114. Also, the voice guidance output unit 102g of the mobile terminal device 100 associates the current position acquired by the process of the current position acquisition unit 102c and the current position hierarchy information acquired by the process of the hierarchy information acquisition unit 102d with the guidance point. If the position information matches, the voice guidance may be executed by outputting voice data corresponding to the guidance point via the voice output unit 116.

  And the control part 102 of the portable terminal device 100 determines whether the user reached | attained the destination (step SA-7).

  And the control part 102 of the portable terminal device 100 determines with the guidance point setting part of the portable terminal device 100, when it determines with the user not having reached | attained the destination in step SA-7 (step SA-7: No). 102e is route guidance data received by the process of the route guidance data receiving unit 102b based on the current position acquired by the process of the current position acquiring unit 102c and the current position hierarchy information acquired by the process of the hierarchy information acquiring unit 102d.

Thereafter, the process proceeds to step SA-11.

  On the other hand, if it is determined in step SA-9 that the display hierarchy information does not match the current position hierarchy information in step SA-9 (step SA-9: No), the guidance point setting unit 102e of the mobile terminal device 100 determines the next guidance point. If it is determined that there is no next guidance point (step SA-11: No), the process returns to step SA-4.

  When it is determined in step SA-11 that there is a next guidance point (step SA-11: Yes), the guidance point setting unit 102e of the mobile terminal device 100 sets the guidance point as a determination target (step SA-11). Step SA-12) Then, the process returns to Step SA-9.

  That is, in steps SA-8 to SA-12, the guidance point setting unit 102e of the mobile terminal device 100 determines the current position acquired by the process of the current position acquisition unit 102c in step SA-4 and the hierarchy in step SA-5. Based on the current position hierarchy information acquired by the processing of the information acquisition unit 102d, the next display from the current position is performed from the guidance point of the route guidance data received by the route guidance data receiving unit 102b in step SA-3. A guide point is selected, and a guide point of display hierarchy information corresponding to the selected guide point is set as a display target. Then, the guidance point display unit 102f displays the guidance points set by the processing of the guidance point setting unit 102e on the display unit 114 in distinction from the guidance points of other display hierarchy information. Here, the guide point display unit 102f may display the guide points set by the guide point setting unit 102e and may not display the guide points of other display hierarchy information. Moreover, the guidance point display part 102f may change the display mode of the guidance point set by the guidance point setting part 102e, and the guidance point of other display hierarchy information.

  When the control unit 102 of the mobile terminal device 100 performs route guidance by repeating the above-described processing, and determines that the user has reached the destination in Step SA-7 (Step SA-7: Yes), The process ends.

  When the control unit 202 of the route search server 200 determines in step SB-9 that the user has not reached the destination (step SB-9: No), the guide point setting unit of the route search server 200 202b is a guidance point of the route guidance data generated by the processing of the route search unit 202a in step SB-2 based on the current location obtained in step SB-4 and the current location hierarchy information obtained in step SB-6. From the current position, the next guidance point to be displayed is selected, and the guidance point is set as a determination target (step SB-10).

  Then, the guidance point setting unit 202b of the route search server 200 sets the display hierarchy information of the guidance point and the step SB-6 for the guidance point to be displayed next from the current position set as the determination target in step SB-10. Corresponds to the current position hierarchy information indicating the hierarchy of the current position acquired in the mobile terminal device 100 (that is, the current position hierarchy information acquired from the position information signal, or the map data displayed on the display unit 114). (Current position hierarchy information acquired from the hierarchy) and by determining whether or not the display hierarchy information and the current position hierarchy information match, it is determined whether to set the guidance point to be determined as a display target (step SB-11).

The guide point that has been set is set as a display target. Then, the guidance point display control unit 202c of the route search server 200 transmits the guidance point set by the processing of the guidance point setting unit 202b to the mobile terminal device 100 (step SB-12), thereby other display hierarchy information. Are drawn separately from the guide points and displayed on the display unit 114 (step SB-13). Thereafter, the process proceeds to Step SB-14.

  On the other hand, when it is determined in step SB-11 that the display hierarchy information and the current position hierarchy information do not match (step SB-11: No), the guidance point setting unit 202b of the route search server 200 determines the next guidance point. If it is determined that there is no next guidance point (step SB-14: No), the process returns to step SB-4.

  When it is determined in step SB-14 that there is a next guidance point (step SB-14: Yes), the guidance point setting unit 202b of the route search server 200 sets the guidance point as a determination target (step SB-14: Yes). Step SB-15) After that, the process returns to Step SB-11.

  That is, in steps SB-10 to SB-15, the guidance point setting unit 202b of the route search server 200 receives the position received from the position transmission device 500 in the position acquisition unit 112 in the mobile terminal device 100 in step SB-3. Position information including latitude and longitude extracted from the information signal is received as the current position of the mobile terminal device 100 in step SB-4, and the hierarchy of the current position acquired in the mobile terminal device 100 in step SB-6 is obtained. Current position hierarchy information is received, and based on the current position and the current position hierarchy information, from the guidance point of the route guidance data generated by the process of the route search unit 202a in step SB-2, Select the guidance point displayed on the It is set as a display target guide point of the display hierarchy information corresponding to.

In addition, the route search device 400 has a function of displaying map data corresponding to the acquired current position and current location hierarchy information of the route search device 400 on the display unit 414 without connecting to the route search server 200. May be. As described above, the third embodiment is different from the other embodiments in that the route search apparatus 400 is configured as a stand-alone type and performs processing alone.

[Configuration of route search apparatus 400 (stand-alone type)]
First, an example of the configuration of the route search apparatus 400 (stand-alone type) in the third embodiment will be described below with reference to FIG.

  As illustrated in FIG. 9, the route search device 400 according to the third exemplary embodiment of the present invention includes a position acquisition unit 412 that receives a position information signal transmitted from the position transmission device 500, a display unit 414, and an audio output unit 416. A control unit 402 and a storage unit 406 are provided at least. Each unit of the route search apparatus 400 is connected to be communicable via an arbitrary communication path.

  In FIG. 9, the functions of the input / output control interface unit 408, the position acquisition unit 412, the display unit 414, and the audio output unit 416 are the same as those in the first embodiment, and thus description thereof is omitted. Further, each function of the storage unit 406 (the network data file 406a, the guidance point file 406b, the map data file 406c, etc.) is different from that of the storage unit 406 except that it is provided in the route search device 400 instead of the route search server 200. However, since it is the same as that of 1st Embodiment and 2nd Embodiment, description is abbreviate | omitted.

  Further, for each part of the control unit 402 (route search unit 402a to map display unit 402g, etc.), the route search device 400 of this embodiment is a stand-alone type and does not include a communication control interface unit. Each function is basically the same as that of the first embodiment except that no transmission / reception function is provided.

  In FIG. 9, the control unit 402 has an internal memory for storing a control program such as an OS (Operating System), a program that defines various processing procedures, and necessary data. And the control part 402 performs the information processing for performing various processes with these programs. The control unit 402 is functionally conceptually a route search unit 402a, a current position acquisition unit 402b, a hierarchy information acquisition unit 402c, a guidance point setting unit 402d, a guidance point display unit 402e, a voice guidance output unit 402f, and a map display unit 402g is comprised.

  Among these, the route search unit 402a searches for route information from the starting point to the destination that satisfies the route search condition including at least the starting point and the destination, and the searched route information and the guidance point file 406b are stored. Route search means for generating guide points and display hierarchy information as route guide data. Here, the route search unit 402a obtains route information composed of nodes (including guide points) and links from the departure point to the destination that satisfy the route search condition including at least the departure point and the destination. A search may be performed using network data stored in the file 406a, and the searched route information, guidance points, voice data, and display hierarchy information stored in the guidance point file 406b may be generated as route guidance data.

  In addition, the current position acquisition unit 402b extracts position information including latitude and longitude from the position information signal received from the position transmission device 500 by the position acquisition unit 412. Current position acquisition means for acquiring the current position.

  The hierarchy information acquisition unit 402c is a hierarchy information acquisition unit that acquires current position hierarchy information indicating the hierarchy of the current position.

  Here, the hierarchy information acquisition unit 402c may acquire the current position hierarchy information from the position information signal received from the position transmission device 500 by the position acquisition unit 412. As an example, when the position transmission device 500 is a GPS device, the hierarchy information acquisition unit 402c indicates a hierarchy (for example, “outdoor 1F”, “rooftop”, etc.) where the user is present based on the altitude included in the position information signal. You may acquire present position hierarchy information. Further, when the position transmitting device 500 is an IMES device, the hierarchy information acquisition unit 402c is based on the hierarchy information included in the position information signal (for example, “underground 1F”, “indoor 1F”, “indoor” 2F "etc.) may be acquired.

  Moreover, the hierarchy information acquisition part 402c may acquire the hierarchy corresponding to the map data displayed on the display part 414 by the map display part 402g mentioned later as present position hierarchy information. As an example, when the hierarchical information acquisition unit 402c is in a building where the user cannot receive a position information signal from the GPS device, and the IMES device is not installed in the building, the user uses the input unit. The layer (for example, indoor 2F) corresponding to the map data of the desired layer (for example, indoor 2F) selected and displayed on the display unit 414 may be acquired as the current position layer information.

  In addition, the guidance point setting unit 402d uses the current position acquired by the current position acquisition unit 402b and the current position hierarchy information acquired by the hierarchy information acquisition unit 402c based on the route guidance data generated by the route search unit 402a. A guidance point setting unit that selects a guidance point to be displayed next from the current position from the guidance points, and sets a guidance point of display hierarchy information corresponding to the selected guidance point as a display target.

  The guidance point display unit 402e is a guidance point display unit that displays the guidance points set by the guidance point setting unit 402d on the display unit 414 in distinction from the guidance points of other display hierarchy information. Here, the guide point display unit 402e may display the guide points set by the guide point setting unit 402d and may not display the guide points of other display hierarchy information. The guidance point display unit 402e may change the display mode of the guidance points set by the guidance point setting unit 402d and the guidance points of other display hierarchy information.

  As an example, the guidance point display unit 402e displays the same display as the next guidance point displayed from the current position by adjusting the transmittance (for example, 1% to 100%, etc.) of the guidance points of other display hierarchy information. You may display separately from the guidance point of hierarchy information. For example, when the transmittance is set to 100%, the guidance points of other display hierarchy information are displayed as if they were deleted, and when the transmittance is set to 50%, the guidance displayed next from the current position is displayed. It is displayed lighter than the guide point of the same display hierarchy information as the point. In addition, the guide point display unit 402e changes the size of the guide point of other display hierarchy information (for example, large size, medium size, small size, etc.), so that it is the same as the next guide point displayed from the current position. You may display separately from the guidance point of display hierarchy information. Further, the guidance point display unit 402e may display only the guidance point of the same display hierarchy information as the guidance point displayed next from the current position in a blinking manner, thereby distinguishing it from the guidance points of other display hierarchy information. Good. In addition, the guidance point display unit 402e highlights only the guidance points having the same display hierarchy information as the next guidance point displayed from the current position (for example, color change, font change, etc.), thereby displaying another display. You may display separately from the guidance point of hierarchy information.

  The voice guidance output unit 402f outputs voice data corresponding to the guidance point via the voice output unit 416 when the current position is located in the vicinity of the guidance point set by the guidance point setting unit 402d. Thus, voice guidance output means for executing voice guidance is provided.

  The map display unit 402g is a map display unit that displays map data stored in the map data file 406c corresponding to the selected hierarchy on the display unit 414.

  Above, description of an example of a structure of the route search apparatus 400 in 3rd Embodiment is finished.

Is acquired as the current position of the route search device 400 (step SC-3).

  And the hierarchy information acquisition part 402c of the route search apparatus 400 acquires present position hierarchy information (step SC-4). Here, the hierarchy information acquisition unit 402c may acquire the current position hierarchy information from the position information signal received from the position transmission device 500 by the position acquisition unit 412. Further, the hierarchy information acquisition unit 402c may acquire a hierarchy corresponding to the map data displayed on the display unit 414 by the processing of the map display unit 402g as the current position hierarchy information.

  Then, the map display unit 402g of the route search apparatus 400 has map data corresponding to the current position acquired by the process of the current position acquisition unit 402b and the current position hierarchy information acquired by the process of the hierarchy information acquisition unit 402c. Is displayed on the display unit 414 to update the map (step SC-5). Here, the map display unit 402g of the route search apparatus 400 may display the map data of the hierarchy selected by the user via the input unit on the display unit 414. The voice guidance output unit 402f of the route search device 400 associates the current position acquired by the process of the current position acquisition unit 402b and the current position hierarchy information acquired by the process of the hierarchy information acquisition unit 402c with the guidance point. If the position information matches, the voice guidance may be executed by outputting voice data corresponding to the guidance point via the voice output unit 416.

  Then, the control unit 402 of the route search device 400 determines whether or not the user has reached the destination (step SC-6).

  When the control unit 402 of the route search device 400 determines in step SC-6 that the user has not reached the destination (step SC-6: No), the guide point setting unit of the route search device 400 Reference numeral 402d indicates guidance of route guidance data generated by the process of the route search unit 402a based on the current position acquired by the process of the current position acquisition unit 402b and the current position hierarchy information acquired by the process of the hierarchy information acquisition unit 402c. By selecting the next guidance point to be displayed from the current position, the guidance point is set as a determination target (step SC-7).

  Then, the guidance point setting unit 402d of the route search apparatus 400 sets the display hierarchy information of the guidance point and the step SC-4 for the guidance point to be displayed next from the current position, which is set as the determination target in step SC-7. Current position hierarchy information acquired by the process of the hierarchy information acquisition unit 402c (that is, current position hierarchy information acquired from the position information signal or current position acquired from the hierarchy corresponding to the map data displayed on the display unit 414) And determining whether or not the display hierarchy information matches the current position hierarchy information, thereby determining whether or not the guidance point to be determined is set as the display target (step SC-8).

  When it is determined in step SC-8 that the display hierarchy information matches the current position hierarchy information (step SC-8: Yes), the guidance point setting unit 402d of the route search device 400 selects in step SC-7. The guide point that has been set is set as a display target. Then, the guidance point display unit 402e of the route search device 400 draws the guidance points set by the processing of the guidance point setting unit 402d separately from the guidance points of other display hierarchy information, and displays them on the display unit 414 ( Step SC-9). Thereafter, the process proceeds to Step SC-10.

  On the other hand, when it is determined in step SC-8 that the display hierarchy information and the current position hierarchy information do not match (step SC-8: No), the guidance point setting unit 402d of the route search device 400 determines the next guidance point. If it is determined that there is no next guidance point (step SC-10: No), the process returns to step SC-3.

  When it is determined in step SC-10 that there is a next guidance point (step SC-10: Yes), the guidance point setting unit 402d of the route search device 400 sets the guidance point as a determination target (step SC-10: Yes) Step SC-11), and then the process returns to Step SC-8.

  That is, in steps SC-7 to SC-11, the guidance point setting unit 402d of the route search apparatus 400 uses the current position acquired by the process of the current position acquisition unit 402b in step SC-3 and the hierarchy in step SC-4. Based on the current position hierarchy information acquired by the process of the information acquisition unit 402c, the next point from the current position is displayed from the guidance point of the route guidance data generated by the process of the route search unit 402a in step SC-2. A guide point is selected, and a guide point of display hierarchy information corresponding to the selected guide point is set as a display target. And the guidance point display part 402e displays the guidance point set by the process of the guidance point setting part 402d on the display part 414, distinguishing it from the guidance point of other display hierarchy information. Here, the guide point display unit 402e may display the guide points set by the guide point setting unit 402d and may not display the guide points of other display hierarchy information. The guidance point display unit 402e may change the display mode of the guidance points set by the guidance point setting unit 402d and the guidance points of other display hierarchy information.

  The control unit 402 of the route search device 400 performs route guidance by repeating the above-described processing, and when it is determined in step SC-6 that the user has reached the destination (step SC-6: Yes), The process ends.

  Above, description of the process of the route search apparatus 400 in 3rd Embodiment is finished.
