JP5762362B2 - Navigation system - Google Patents

Description

  The present invention relates to a navigation system, and more particularly, to a navigation system for visually handicapped persons (people with blindness).

  In the navigation system, the route from the departure point specified by the user to the destination is searched to generate navigation data, and the route obtained as a result of the search is displayed on the map displayed on the display screen. While displaying the current position mark of the user, guidance is provided according to the movement of the user. It also has a function of providing guidance by voice based on navigation data at intersections and corners. The user can move to the destination according to the guidance while referring to the voice guidance while confirming his / her position on the map on the display screen.

  As described above, since a navigation system has also been accompanied by voice guidance, even a visually impaired person can rely on the voice guidance. Since the voice guidance does not take into account the degree of importance, the guidance information is insufficient for the visually impaired, and the actual situation is that it cannot be used in practice.

  An audio road guidance navigation system in consideration of this point is proposed in, for example, Japanese Patent Application Laid-Open No. 2001-4396. In the navigation system of this patent document 1, a visually handicapped person, for example, when he / she goes out, from the mobile radio terminal he / she owns when he / she cannot understand his / her current position or his / her route on the way. Sends position information and direction information to the navigation transmitter to make an inquiry. Then, in response to this inquiry, the navigation transmission device is in the case where the visually handicapped person is out of the route to the destination entered before going out, such as the place name, address name, etc. Information such as the return method is transmitted to the mobile radio terminal by voice.

  Therefore, if you are blind, you can listen to the sound emitted from the speaker of the mobile radio terminal to get information on the place name, street name, etc. where you are, and the destination you entered before going out. It is possible to know the return method in the case of deviating from the route.

[Operation when the navigation service server 20 receives access from the mobile phone terminal 4]
Next, the operation flow when the navigation service server 20 having the above-described configuration receives an access by the visually handicapped person from the mobile phone terminal 4 will be described with reference to the flowcharts of FIGS. 7 and 8. To do. The example of FIGS. 7 and 8 will be described as a case where the control unit 201 realizes the processing functions of the reception information processing unit 203 and the transmission information generation unit 210 as the software processing functions.

  First, the control unit 201 of the map information providing server 20 monitors and waits for reception of access from the mobile phone terminal 4 (step S101). When it is determined that the access has been received, the access is a URL for the visually impaired. It is determined whether or not the access is to (step S102).

  If it is determined in step S102 that the access is not to the URL for the visually impaired but the URL for the healthy person, the control unit 201 displays the Web page providing unit 205, the map information storage unit 206, and the navigation system. From the service support program providing unit 207, a processing routine for providing and providing a web page, map information, and a navigation service support program for the healthy person to the accessing person is executed (step S103).

  If it is determined in step S102 that the access is to the URL for the visually impaired, the control unit 201 sends the ID and password to the accessing person who is visually impaired from the Web page providing unit 206. A voice message requesting transmission is read out and transmitted to the mobile phone terminal 4 of the accessor (step S104).

  The accessor sends an ID and a password from the mobile phone terminal 4 in response to this voice message. Therefore, the control unit 201 determines whether an ID and a password are received from the accessed mobile phone terminal 4 (step S105). When it is determined in step S105 that the ID and password have not been received, the control unit 201 determines whether there is an instruction to end access (step S106), and when it is determined that there is no instruction to end. The process returns to step S105, and the processes after step S105 are repeated. When it is determined in step S106 that there is an instruction to end access, the control unit 201 performs an end process (step S111), and ends this processing routine.

  When it is determined in step S105 that the ID and password are received, the control unit 201 receives the received ID and password, and the visually impaired member ID and password registered in the visually impaired member information registration unit 204. And whether it is a registered visually handicapped person or not is determined based on whether or not there is a match (step S107).

  When it is determined in step S107 that the person is not a registered visually impaired person, the control unit 201 transmits a message (display message and voice message) indicating that the ID and password are not registered (step S108).

  Then, the control unit 201 determines whether or not there is an instruction to end access (step S109). When it is determined that there is no instruction to end, it determines whether or not the ID and password are received again (step S110). If it is determined that the signal has been received again, the process returns to step S107, and the processes after step S107 are repeated. If it is determined in step S110 that the ID and password have not been received again, the control unit 201 returns the process to step S109.

  When it is determined in step S109 that there is an instruction to end access, the control unit 201 performs an end process (step S111) and ends the process routine.

  If it is determined in step S107 that the accessing person is a registered visually handicapped person, the control unit 201 searches and accesses the visually impaired member information registering part 204 using the acquired ID as a searcher. The visually-impaired degree attribute of the visually-impaired person is recognized (step S121 in FIG. 8).

  Then, the control unit 201 reads out the web page for the visually handicapped person with the display specification corresponding to the recognized visual inconvenience degree attribute from the web page providing unit 205, transmits the web page to the mobile phone terminal 4, and the navigation service. A support program corresponding to the recognized visual inconvenience degree attribute is read from the support program providing unit 207 and transmitted to the mobile phone terminal 4 (step S122).

  The mobile phone terminal 4 displays the provided web page on the display screen and emits voice guidance accompanying the web page. The user (visually impaired person) of the mobile phone terminal 4 designates a departure place, a destination, a moving means, and a moving purpose in accordance with the display of the web page or voice guidance, and makes a search request accompanied with them as information. Perform a send operation. Here, the moving means are walking, car, bicycle, motorcycle, bus, train and the like. The purpose of travel is shopping, walking, meetings, and others.

  Therefore, the control unit 201 waits to receive a search request with a departure place, a destination, a moving means, and a moving purpose from the mobile phone terminal 4 (step S123). When the control unit 201 confirms the reception of the search request in step S123, the control unit 201 is map data corresponding to the visual inconvenience degree attribute of the area necessary for route guidance, and the visual inconvenience degree recognized in step S121. Map data of display specifications corresponding to the attribute is transmitted to the mobile phone terminal 4 (step S124).

  Further, the control unit 201 uses the navigation data generation unit 208 to perform a route search that matches the received departure point, destination, moving means, and moving purpose information using the map data corresponding to the visual inconvenience degree attribute. The generated navigation data of the search result is transmitted to the mobile phone terminal 4 (step S125). As described above, this navigation data includes scenario data corresponding to the visual inconvenience degree attribute.

  Next, the control unit 201 waits for an instruction to end access (step S126). When the control unit 201 confirms the instruction to end, the control unit 201 performs an end process (step S127) and ends this processing routine.

[Navigation by the support program in the mobile phone terminal 4]
When a visually handicapped person who is a user of the mobile phone terminal 4 gives an instruction to start predetermined guidance navigation, the flowcharts shown in FIGS. 9 and 10 are started. The processing of each step described below is executed by the control unit 401 of the mobile phone terminal 4 according to the support program provided from the navigation service server 20.

  First, in response to a guidance start instruction from the user, the control unit 401 synthesizes a voice that tells the start of guidance, such as “starts route guidance” by the voice synthesis unit 415 and emits sound from the speaker 421. (Step S201).

  Next, the control unit 401 detects the current position from the current position information measured by the GPS positioning unit 407, and displays the current position on the map displayed on the display screen (step S202). Then, the navigation data is referred to by the position information of the detected current position (step S203), and it is determined whether or not the detected current position is a position set to notify the guidance by synthesized voice (step S204). .

  When it is determined in step S204 that the detected current position is a position that is set to notify the guidance by synthetic voice, the control unit 401 stores the navigation data stored in the navigation data temporary storage unit 409. According to the scenario data included, the guidance notification voice is synthesized based on the map data stored in the map data memory 410 and emitted from the speaker 421 (step S205).

  For example, for example, as map data, there is data indicating that there is a stairway that goes down to the basement on the left side of the road 20 meters from the current point. As scenario data, the distance to the staircase and the destination of the staircase are notified. Is defined, the control unit 401 controls the voice synthesis unit 415 to synthesize and output a voice saying “There is a staircase that goes down to the left side of the road 20 meters ahead”. To do.

  When the map data indicates that there is a braille block nearby, the control unit 401 synthesizes and outputs, for example, a voice “There is a braille block on the right side of the sidewalk” based on the scenario data. . In addition, when the current position is in the train and the train is moving, the control unit 401 synthesizes a voice “Next is XX station. The right door opens” based on the scenario data. And output.

  After step S205, the control unit 401 determines whether or not a voice from the user (visually impaired person) is input through the microphone 421 (step S206). In addition, when it is determined in step S204 that the current position is not a position set for notifying guidance by synthesized speech, the control unit 401 jumps to step S206 to detect from the visually impaired person. It is discriminated whether or not the voice is input.

  When it is determined in step S206 that the voice from the visually handicapped person has been input, the control unit 401 recognizes the voice input by the voice recognition unit 416 and grasps the contents of the question from the visually handicapped person. (Step S207).

  Next, the control unit 401 uses the scenario for the answer voice included in the navigation data stored in the navigation data temporary storage unit 409 to answer the question content (question) from the visually handicapped grasped in step S207. According to the data, the guidance notification voice is synthesized based on the map data stored in the map data memory 410 and emitted from the speaker 421 (step S208).

  For example, when a visually handicapped person asks a question such as “Is there a convenience store nearby?”, The control unit 401 of the mobile phone terminal 4 is “on the first floor of a building 50 meters away. Is generated and output from the speaker 421.

  Next, the control unit 401 monitors the outputs of the gyro sensor 411, the acceleration sensor 113, and the GPS positioning unit 407, and the position of the mobile phone terminal 4 has moved, that is, the visually impaired person who has been a user has moved. Whether or not (step S209). If it is determined in step S206 that no sound from the visually impaired is input, the control unit 401 bypasses steps S207 and S208 and jumps to step S209.

  When it is determined in step S209 that the visually impaired person who is the user has moved, the control unit 401 returns the process to step S202, and repeats the processes after step S202. If it is determined in step S209 that the visually handicapped person who is not moving is not moving, guidance is given because the user has arrived at the destination or has been compulsorily instructed by the user. It is determined whether or not the navigation is complete (step S210). When it is determined that the navigation is complete, this processing routine is terminated. When it is determined in step S210 that the process is not ended, the control unit 401 returns the process to step S209, and repeats the processes after step S209.

  In this embodiment, the navigation service support program executes voice guidance such as alerting based on the camera video of the camera unit 414 in parallel with the processing operation shown in the flowchart of FIG.

  That is, when the navigation service support program is activated, in parallel with the processing operation shown in the flowchart of FIG. 9, the control unit 401 operates the camera unit 414, captures the camera video, and supplies it to the image recognition unit 417. Thus, image recognition is performed (step S221 in FIG. 10).

  Then, the control unit 401 is in a situation where the image recognition result of the image recognition unit 417 requires guidance notification such as “the traveling direction is congested” or “there is a step” as described above. It is determined whether or not there is (step S222). Then, when it is determined in step S222 that the situation requiring guidance notification is present, the control unit 401 interrupts the processing of FIG. According to the scenario data included in the navigation data stored in the temporary storage unit 409, the guidance notification voice is synthesized and emitted from the speaker 421 (step S223).

  Next, the control unit 401 determines whether or not the guidance navigation is terminated due to the arrival at the destination or the forced termination instruction given by the user (step S224). When it is determined that there is, this processing routine is terminated. When it is determined in step S224 that the process is not finished, the control unit 401 returns the process to step S221 and repeats the processes after step S221.

[Effect of the first embodiment]

  In the second embodiment, the visual inconvenience degree attribute registration server of the navigation service site 3 is dedicated to accessing the navigation service server 20 for visually impaired persons who have registered the visual inconvenience degree attribute. Is requested to access the navigation service site 20 through this dedicated URL. The visually handicapped person can receive provision of the service by accessing the navigation service server 20 using the URL dedicated to the visually impaired person as described above.

  According to the second embodiment, a visually handicapped person accesses the navigation service site 3 and registers his / her own visual disability degree attribute, thereby providing the navigation service server 20 of the navigation service site 3. A possible navigation service can be provided regardless of the visual inconvenience level attribute.

[Third Embodiment]
In the above embodiment, the visual inconvenience degree attribute is registered on the site (server) side, and on the site side, the visual inconvenience degree attribute of the accessor is recognized based on the accessor ID and password. The contents of the navigation service provided correspond to the visual inconvenience level attribute.

  However, when the mobile terminal such as the mobile phone terminal 4 stores and holds the visual inconvenience degree attribute and accesses the navigation service site 3, the information on the visual inconvenience degree attribute is used as the navigation service site 3 navigation service 3. You may comprise so that it can transmit to the server 20 and the navigation service according to the visual inconvenience degree attribute can be received.

  The third embodiment is an example in that case. That is, in the third embodiment, the mobile terminal provides means for providing a user with a voice question and receiving an answer to the question in order to determine and register the visual inconvenience degree attribute. Prepare. And a mobile terminal is provided with the function which determines a visual inconvenience degree attribute based on the received answer, and registers and memorize | stores it in a memory | storage part.

  When the mobile terminal accesses the navigation service server 3, the mobile terminal transmits the stored information on the visual inconvenience attribute of the accessor to the navigation service server 3.

  On the other hand, the navigation service server 3 recognizes the visual inconvenience degree attribute included in the access information sent from the mobile terminal and provides the corresponding navigation service to be provided as described above. It has a function that depends on the visual inconvenience attribute of the person.

  In the case of the third embodiment, there is an advantage that the navigation service site 3 does not need to store visually impaired member information.

[Other Embodiments and Modifications]
In the first to third embodiments described above, the navigation service server is configured to prepare a URL for the visually handicapped person and treat an accesser to the URL as a visually handicapped person. Since the ID is registered as the visually impaired member information, it is determined whether or not the accessing person is a visually impaired person by referring to the ID at the time of access. When the user is a user, the same processing as when accessing the URL for the visually impaired described above may be performed.

  For example, when a visually-impaired person accesses the server for visually-impaired degree attribute registration, the user is informed of the telephone number, and the operator on the server side makes a phone call to the telephone number.
