FIG. 7 is a flowchart showing the flow of guidance for the visually impaired by the guidance and guidance system for the visually impaired according to the first embodiment of the present invention. This will be described with reference to FIG.

First, a user as a visually impaired person is detected (51).

Upon detection of the user, the guide device transmits a request command for an ID (identification number) from the transmitting / receiving device 2 installed near each entrance of the facility (51a). The portable terminal unit 9b, which has received this signal at the transmission / reception device 22, recognizes the command by the control device 21, transmits its own ID from the transmission / reception device 22, and responds (51b). When this response signal is received by the transmission / reception device 2, the guidance guide device detects that a user has entered the facility, and grasps which entrance is near (51c). Here, the transmission distance of the transmission / reception device 2 may be short.

When a plurality of transmission / reception devices 2 are installed in a small facility, it is possible to identify the vicinity of a user by knowing the level of the received signal. However, even if the position cannot be specified here, the position detection method described below can be used. In addition, the mobile terminal unit 9 of the already detected user
By transmitting a request for not responding to the ID transmission request after detecting the new user, the new user can be detected even when a new user enters the entrance. Becomes

After the guide device detects a new user, a program is executed on the guide server 1 to guide the user of the detected ID to a management mode (hereinafter, referred to as a "guide mode"). Abbreviated as "). The guidance mode continues until the user leaves the entrance of the facility.

When the user of the ID recognized at each entrance is in the guide mode, the guide server 1 of the guide device periodically grasps the position of the user (52).

In this position grasp, the communication signal 11 for the position detection signal request is transmitted from the transmitting / receiving device 2 near the portable terminal 9b.
Is transmitted (52a). The ID of the user requesting a response is added to the communication signal 11 as tag information. The communication signal 11 is received by the transmission / reception device 22 in the portable terminal unit 9b carried by the user, and the control device 21 transmits the communication signal 11 to the user.
D and a transmission request for a position detection signal, the communication signal 2
7, a transmission request of the infrared signal 10a and the ultrasonic signal 10b is transmitted to the stick 9a. Transmission / reception device 16 in cane part 9a
Receives the communication signal 27 and controls the control device 15 of the walking stick 9a.
Recognizes this and drives the transmitting device 14 to transmit the infrared signal 10a and the ultrasonic signal 10b. Transmission device 1
Since 4 is incorporated in the upper part of the staff 9a of the user, both the infrared signal 10a and the ultrasonic signal 10b are easily transmitted toward the ceiling (upward). The infrared signal 10a and the ultrasonic signal 10b can be easily received by the receiving device 3 installed on the ceiling 8, and the position to the user is calculated by the arithmetic and control unit 33 in the receiving device 3.

The arithmetic and control unit 33 transmits the infrared signal 10a and the ultrasonic signal transmitted simultaneously from the cane 9a and detected by the infrared receiving device 31 in the receiving device 3 and the plural ultrasonic receiving devices 321 to 324, respectively. Based on the difference between the receiving times of 10b (ultrasonic receiving time-infrared receiving time), the distance from each of the ultrasonic receiving devices 321 to 324 to the staff 9a of the user was calculated, and the position of the receiving device 3 was calculated. Ascertain the position from intersections from multiple distances. Here, since the three-point surveying technique is used to calculate the position, the position of the cane 9a can be calculated with high accuracy, and the position of the user can be grasped. The position information thus obtained is transmitted to the transmitting device 3
4 to the guidance server 1 via the connection communication means 4.

When it is found that a plurality of users are present in the same area, the location detection request is made separately in time while changing the ID added earlier.
Each position detection can be performed using the same receiving device 3.

The guidance guidance server 1 executes the guidance guidance program to manage the locus of the position of the portable terminal unit 9b for each ID with time based on the obtained position information (53a). In addition, guidance information server 1
Predicts the next request based on the position and the trajectory of the mobile terminal unit 9b (53b), and provides the user with guidance according to the prediction result and the response result of the guidance guidance.

For example, when a user is detected at the entrance of the facility, guidance 1 is provided (54). The guidance 1 is transmitted as voice guidance data with an ID tag from the guidance guidance server 1 via the transmission / reception device 2 (54a).
When received by the portable terminal unit 9b having the matching D, a voice is generated by the voice conversion device 24 and the earphone 12
The sound is further output (54c).

Example of Guide 1: (Guidance 1a) "This is the entrance to the XX facility. Welcome, thank you for using." (Guidance 1b) "The following services are available at this XX facility." Ticket sales and reservation. 2nd music CD viewing, 3rd break, 4th toilet, 5th, etc. "Please select your desired service number. We will guide you according to your selection. "If you want to hear about the service again, please select number 7.""If you have any questions, please call the reception desk. 7
・ At 7, it will be in telephone mode for voice connection. According to such guide 1, the user presses the input button 18 disposed on the grip of the cane 9a to select a number suitable for his purpose (54d). Here, since the input button 18 is disposed on the grip of the cane 9a, the user can operate the device without holding it, which is convenient. When the input device 17 detects that the input button 18 has been pressed, the content is transmitted from the transmission / reception device 16 to the portable terminal unit 9b by the control device 15, and its own ID information is added to the content. Sent from (54
e). The result of selection for guide 1 received by the transmitting / receiving device 2 is sent to the guide server 1 via the connection communication means 4, and the guide program recognizes the user's request (54f). The recognized user's request is subjected to request prediction and corresponding processing by the guidance guide program (53).
b).

Here, when the user selects the toilet,
The guidance program determines the user's personal information (personal information such as whether it is a man, a woman, a wheelchair, etc.) from the ID number, searches for a route from the current location to the most accessible toilet, and provides guidance on this content. To the user by voice or vibration (55). However, the route search and the guidance may be provided by providing information selected from the current position, the purpose (position), and the personal information from the guide database prepared in advance.

An example of the toilet guidance (guide n) will be described in more detail with reference to FIG. FIG. 8 is a plan view showing an outline of guidance for visually impaired persons by the guidance and guidance system for visually impaired persons according to the first embodiment of the present invention. In FIG. 8, 7a is a vending machine for selling tickets, 7b is a vending machine for selling juice, 7c is a vending machine for selling tobacco, 81, 82, 83 are entrances, 8
4 and 85 are stairs and 86 is a wall.

In FIG. 8, the guidance program derives the shortest men's restroom P2 on the same floor from the current location P1 based on personal information (male, walkable person) recognized by ID from the current location P1. The route to the male toilet P2 to be searched is searched with reference to the map information recorded in the facility (P1 → P11 → P2). Here, P11 is a target position on the way. Then, the obtained route is transmitted as the guidance data of the voice guidance n (55a). Here, a user ID is added to this data as a tag. When this guidance information is received by the portable terminal unit 9b whose ID matches, the voice conversion device 2
4 generates a voice from the guidance data, the earphone 12
And outputs the output to guide the user (55b). This also eliminates the need to listen to other people's guidance. Here, an example of guidance is "Mr. XX. The men's toilet has an entrance 10m in front of the current location and 6m after turning right.""If this guidance is not good, number 7 twice. Please enter. "

When the visually impaired hears this guidance (55c) and starts moving (55d), the guidance guidance program starts.
While sequentially grasping the position of the visually impaired person in the position detection procedure (52), the guidance (55) is repeated according to the moved position.

For example, when the visually impaired person starts to move in a different direction P3 instead of the intended front, the guidance guidance is “Mr. XX.
Please change the direction every time. ". Here, it is also possible to vibrate the cane portion 9a with the vibration generating device 19 incorporated in the cane portion 9a to call attention of the user. Further, when the visually impaired person has a risk of colliding with an obstacle such as a sofa or a table, the vibration of the cane 9a by the vibration generator 19 can be increased to draw the user's attention.

In another example, when the visually impaired person is confused near the target position P2, the guidance guidance is “XX”.
San. On the left is the men's toilet and on the right is the women's toilet. "Please proceed to the door on the left.""I will start the vibration guidance mode now." Here, the vibration guidance mode is to calculate the distance between the target position and the position of the visually impaired person, and when the user moves away from the target position P2, the walking stick 9a
A portable terminal unit 9b designated by adding an ID tag from the guidance and guidance server 1 so that the vibration of the cane unit 9a by the vibration generator 19 built in the vehicle is increased and the vibration is reduced when approaching.
By sending the information to, it is also possible to guide the user in detail.

When the user selects the number 7 by inputting the input button 18 (55e) in order to cancel the guidance guidance once selected during the guidance, the portable terminal 9b provides guidance n. (55f), the transmission / reception device 2 receives this signal, transmits it to the guidance server 1, and recognizes this request by the guidance server 1 (55g). The guidance guidance program performs & response (53b).

For example, except for the guide 1a, the contents from the guide 1b are provided as the guide 1 (54).

When the user selects the ticket sales and reservation of No. 1 in Guide 1 above, similarly to Guide n, the user is guided to the intended vending machine 7a. The vending machine 7a includes the transmission / reception device 2 and the voice output device 6 similar to the vending machine 7 described in FIG. When detecting that the visually impaired person has arrived at the vending machine 7a, the guidance guidance server 1 provides the following guidance 2.

Example of guide 2: (guide 2a) "Mr. XX. I arrived in front of the vending machine." (Guide 2b) "I can do ticket sales and reservations." In this case, please enter number 1. If you wish to make a reservation, enter number 2. "Here, if the user selects number 1, (Guidance 2c)" Introduce the tickets currently being sold (Guidance 2d) "If you want to play soccer, number 1.
No. 2 if you would like a concert in the hall. ...
·Please enter. "

Here, when the user selects No. 2, as detailed guidance for the purpose, (Guidance 2e) "If you want to perform a concert of the XX band, select the number 1. If you wish, number 2.
····Please enter. "

Here, when the user selects No. 1, as detailed guidance for the purpose, (guidance 2f) "It is a concert of the XX band. The date is XX month." Is $ 5,000 for Seat A and $ 3000 for Seat B. "" Mr. XX. If you want Seat A, please number 1. If you want Seat B, please enter No.2. In this manner, the guidance guidance is provided by exchanging information between the guidance guidance server 1 and the user in both directions.

The input of the number is performed by the input device 17 shown in FIG.
In this example, since three input buttons 18 are used, it is possible to input 1 to 7 by a combination of the pressing. Here, by adding a voice recognition function to the portable terminal unit 9b in selecting the guidance, it is possible to replace the key input by the voice input from the microphone 13.

In the above description, the method of conducting the guidance by exchanging information between the guidance device and the portable terminal on the user side has been described.
