Next, when passing through the intersection CX2, the carrier utters, for example, "Register this convenience store" after the point registration start operation. Finally, the wearer utters, for example, "Register this slope" after the point registration start operation when passing the road R3. Then, at each point registration start operation and at each subsequent utterance, the microphone 23 collects each of the utterances, generates the corresponding sound data, and sends the sound data to the processing unit 20 each time it is generated. Output. Then, the processing unit 20 associates each of the sound data (excluding the voice data corresponding to the location registration start operation) with the detection data (including the corresponding position data indicating the current position) at each time point. , for example, each time it is uttered (except for the voice for the location registration start operation), it is transmitted to the server SV via the interface 28 and the network NW. As will be described in detail later, the server SV records pairs of sound data and detection data transmitted from the location information transmission terminal T in a mutually identifiable and non-volatile manner as guide location data PT, which will be described later. do.

Also, the processing unit 30 is composed of a voice guidance unit 30A and a guidance control unit 30B. At this time, the voice guidance unit 30A and the guidance control unit 30B may be implemented by a hardware logic circuit that constitutes the processing unit 30, or may process a program corresponding to guidance processing as the route generation/guidance system of the embodiment. It may be implemented in software by the unit 30 reading from the recording unit 31 and executing it.

In the above configuration, the recording unit 31 non-volatilely records programs, voice data, etc. necessary for the guidance terminal G to fulfill its functions as part of the functions of the route generation/guidance system of the embodiment. , are read by the processing unit 30 as necessary. Further, under the control of the processing unit 30, the sensor unit 35 detects the current position, moving speed, traveling direction, etc. of the guide terminal G using the GNSS, etc., and generates and processes detection data indicating the detection results. Output to unit 30 . Furthermore, under the control of the processing unit 30, the speaker 37 emits sounds such as guidance voices necessary for the above-mentioned functions that the guidance terminal G should be responsible for. Furthermore, the microphone 33 collects sounds around the guidance terminal G under the control of the processing unit 30 and outputs sound data corresponding to the sound collection results to the processing unit 30 . Under the control of the processing unit 30 , the camera 34 also outputs image data corresponding to, for example, the result of imaging the surroundings of the guide terminal G to the processing unit 30 .

On the other hand, under the control of the processing unit 30, the display 36 displays images, maps, etc. necessary for the above-mentioned functions that the guidance terminal G should handle. Furthermore, under the control of the processing unit 30, the interface 38 controls transmission/reception of information or data necessary for the above-described functions that the guide terminal G should handle to/from the server SV via the network NW. Further, when an instruction operation to the guide terminal G is performed by a visually impaired person carrying the guide terminal G, the operation unit 32 generates an operation signal corresponding to the instruction operation and outputs it to the processing unit 30 . With these, the processing unit 30 controls each member such as the sensor unit 35, the speaker 37, and the interface 38 that constitute the guide terminal G, and controls the performance of the above functions that the guide terminal G should be responsible for.

Here, the functions of the guidance processing as the route generation/guidance system of the embodiment executed mainly by the guidance terminal G and the route generation unit 4 of the server SV are recorded using the guidance point data recording system of the embodiment. The guidance point data PT is illustrated in FIG. 4(b), and a visually impaired person carrying a guidance terminal G walks to the destination GL via intersections CX1 and CX2 illustrated in FIG. 3(b). As an example, the case of doing so will be described with reference to FIG. 5(b).

That is, a visually impaired person carrying a guidance device G is at the departure point ST illustrated in FIG. Suppose you request guidance for walking (as a visually impaired person) to In this case, the guidance control unit 30B generates a transmission request for the route data from the departure point ST to the destination GL, attaches identification information for distinguishing the guidance terminal G from other guidance terminals G, , the interface 38 and the network NW to the server SV. As a result, the route generation unit 4 (see FIG. 4A) of the server SV refers to the guide point data PT illustrated in FIG. -> Intersection CX1 -> Road R2 -> Intersection CX2 -> Road R3 -> Route data indicating a route R (see FIG. 5B) passing through the destination GL is generated. The route data at this time includes position data and characteristic data (see FIG. 4B) corresponding to the intersection CX1, the road R2, the intersection CX2, and the road R3. Then, the route data is transmitted by the processing unit 10 to the guidance device G via the interface 1 and the network NW, using the identification information of the guidance terminal G that has transmitted the transmission request as a clue.

Next, the guidance control unit 30B and the voice guidance unit 30A of the guidance terminal G which have received the route data via the network NW and the interface 38, based on the route data, the bakery BK, the road R2, the convenience store CS and road R3 as guide points, respectively, the walking movement of the visually handicapped person carrying the guide terminal G is guided.

More specifically, first, the guidance control unit 30B detects the timing when the visually impaired person carrying the guidance terminal G approaches the intersection CX1 (that is, when the visually impaired person smells the bread) based on the detection data from the sensor unit 35. At the timing when the driver starts to feel it, a guidance voice such as "Turn left at the intersection in front of the bakery." After the visually impaired person makes a left turn at the intersection CX1 according to the guidance voice, the guidance control unit 30B next instructs the visually impaired person carrying the guidance terminal G to walk along the road R2 based on the detection data from the sensor unit 35. At the start timing (that is, the timing at which the gravel road is sensed), the voice guidance unit 30A emits a guidance voice such as "Go straight on the gravel road for a while" through the speaker 37. Next, at the timing when the visually impaired person walks along the road R2 according to the guidance voice and approaches the intersection CX2 (that is, at the timing when the visually impaired person starts hearing the sound from the convenience store CS), "At the intersection in front of the convenience store, Turn right." After the visually impaired person turns right at the intersection CX2 according to the guidance voice, the guidance control unit 30B finally instructs the visually impaired person carrying the guidance terminal G to walk along the road R3 based on the detection data from the sensor unit 35. At the start timing (that is, at the timing when the user gets the sense that the road is on a slope), the voice guide section 30A emits a guidance voice such as "If you go up the slope, you will reach your destination." By the series of guidance voices described above, the visually impaired person carrying the guidance terminal G can receive guidance for walking movement along the route R with the guidance point being a feature that the user can easily recognize.

Here, a case where the navigation system SS of the embodiment including the guidance point data recording system of the embodiment and the route generation/guidance system of the embodiment is used to guide the visually handicapped person's walking movement from the departure point to the destination, FIG. 6 shows a comparison with the case where a healthy person is guided to move from a similar starting point to a destination.

That is, when an able-bodied person walks from the starting point ST illustrated in FIG. 6 to the destination GL, for example, guidance processing is performed via the shortest route R' illustrated by the broken line in FIG. On the other hand, when a visually impaired person walks from the same departure point ST to the destination GL using the navigation system SS of the above embodiment, the visually impaired person easily recognizes the bakery BK, which smells like bread. , an intersection with a traffic light SG with an audio assist function, a convenience store CS with a unique sound, and a route R indicated by a dashed line in FIG. However, it is safe for the visually impaired to walk along the route R) (see the white arrow in FIG. 6).

As described above, according to the navigation system SS including the guidance point data recording system of the embodiment and the route generation/guidance system of the embodiment, sound data indicating a guidance point that can be recognized by a visually impaired person, and Guidance point data PT for the visually impaired is recorded in the map data MP based on the position data indicating the position of the guidance point. Then, in response to the transmission request of the route data to the destination GL, a route including guidance points for the visually impaired is generated, and the route data indicating the generated route is addressed to the guidance terminal G, which is the source of the transmission request. Send to Therefore, while a route including guide points that even a visually impaired person can recognize is shared by a plurality of people, the visually impaired person can be guided safely using the route.

Further, the guidance point data PT is based on sound data corresponding to the utterance content of the visually impaired or able-bodied person (i.e., the carrier) speaking about the guidance point. It is recorded in the map data MP in association with the data. Therefore, the information indicating the guide points for the visually impaired can be recorded in the map data MP simply by the person carrying the point information transmitting terminal T speaking about the guide points that the visually impaired can recognize.

Furthermore, if the facility or the like that is the guidance point indicated by the guidance point data PT is a facility or the like that emits at least one of sounds or smells that can be recognized by the visually impaired, it is easy for the visually impaired to recognize. Information indicating the guide point can be recorded in the map data MP.

Furthermore, since the position data acquired together with the sound data corresponding to the guidance point is the position data indicating the position of the mobile phone when speaking about the guidance point (see FIG. 3(b)), it is useful for the visually impaired. Based on the position of the speaker who actually visited the position of the guide point, the guide point for the visually impaired can be accurately recorded in the map data MP.

Also, if the person who carries the point information transmission terminal T is visually impaired, it is possible to record and share guide points that are truly useful for the visually impaired based on their experience in the map data MP.

Further, according to the guidance point data recording system of the embodiment, guidance point data for the visually impaired person is generated based on the sound data indicating the guidance point that can be recognized by the visually impaired person and the position data indicating the position of the guidance point. PT is recorded in the map data MP. Therefore, it is possible to record map data MP for sharing a route including guide points that can be recognized even by a visually handicapped person with a plurality of people.

Furthermore, according to the route generation/guidance system of the embodiment, the map data MP is recorded on the basis of the sound data indicating the guide points that can be recognized by the visually impaired and the position data indicating the positions of the guide points. A route including guidance points for the visually impaired is generated, and route data indicating the generated route is transmitted to the guidance terminal G, which is the source of the transmission request for the route data. Therefore, while a route including guide points that even a visually impaired person can recognize is shared by a plurality of people, the visually impaired person can be guided safely using the route.

It should be noted that, in the above-described embodiment, the degree of visual impairment in visually impaired persons is not taken into consideration. However, when the sound data and detection data are transmitted from the point information transmission terminal T, it may be configured to be transmitted with a distinction of the applicable degree of visual impairment (for example, distinction between low vision and blind). good. In this case, the guide point data recorded in the server SV corresponds to the degree of visual impairment. It is possible to provide safe guidance according to the degree of visual impairment.

Also, a program corresponding to each function of the guidance point data recording system of the embodiment and the route generation/guidance system of the embodiment is recorded on a recording medium such as an optical disk or a hard disk, or obtained via a network such as the Internet. By reading this into a general-purpose microcomputer or the like and executing it, the microcomputer or the like can function as the processing unit 10, the processing unit 20, or the processing unit 30 according to the embodiment.
