Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a visually impaired person guiding system for safely monitoring and guiding a visually impaired person to a destination.

[0002]

2. Description of the Related Art Conventionally, a visually impaired person is guided by a healthy person to a destination or by a walking band having a projection provided on a sidewalk.

[0003]

However, the above-mentioned conventional guidance of visually impaired persons has the following problems. In other words, when a healthy person is guided along with a visually impaired person, it is necessary for the healthy person to always be guided to the destination while checking the safety of road conditions, etc. without leaving the side of the visually impaired person. Burden on the elderly. In addition, even when using the guide zone provided on the sidewalk, it is necessary for the visually impaired person to memorize the directions to the destination in advance, and the visually impaired person confirms the directions even if the directions are wrong. It was a difficult problem. The present invention has been made in order to solve the above-mentioned problems relating to the conventional visually impaired person guidance system, and provides a visually impaired person guidance system that enables even a visually impaired person to safely reach a destination. With the goal.

[0004]

According to the present invention, there is provided a visually impaired person guiding system according to the present invention.
According to the invention described above, a slave station device including a position detection unit that detects a current position, a transmission unit, a reception unit, and an image input unit for collecting image information around the current position is connected to a communication line. By transmitting the position information and the image information to the master station device via the master station device, a person carrying the slave station device is monitored and guided from the master station device. The invention according to claim 2 of the visually impaired person guidance system according to the present invention is directed to the visually impaired person guidance system according to claim 1, wherein the position detection means receives a radio wave from an artificial satellite to detect a position. Use the device.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on illustrated embodiments. FIG. 1 is a schematic block diagram showing an embodiment of a visually impaired person guidance system according to the present invention.

[0006] The visually impaired person guidance system shown in this example is:
GPS (Grobal P) in which the visually impaired 1 receives radio waves from a plurality of
ositioning System) and has a wireless terminal device 10 including a digital mobile phone 12 (Personal Digital Celler, hereinafter referred to as PDC) having a transmitter 12a as a transmitting means and a receiver 12b as a receiving means. Also equipped with a digital camera 13 as an image input means, INDS (Integrated serviced digita) to guide the visually impaired 1
public communication lines such as
A telephone terminal 34 connected to a wireless communication base station (fixed station) 33 via a switch 31 and an exchange 32, and a decoder 35 for displaying an image of the current position of the visually impaired person 1 and its surroundings, respectively.
And first and second indicators 36 and 37 connected to the telephone terminal 34 via the.

[0007] The visually impaired person guiding system shown in FIG. 1 functions as follows. First, when a guide (not shown) calls the PDC 12 possessed by the visually impaired person 1 using the telephone terminal 34, the GPS receiver 11 built in the wireless terminal device 10 operates to detect the current position and to visually detect the current position. A digital camera 13 mounted near the abdomen of the handicapped person takes a picture of the surrounding scenery as image information once every few seconds and outputs this information to the PDC 12 as a digital signal.

The signal relating to the image information is photographic data which is photographed once every several seconds as described above. Is enough.

Then, the transmitter 12a of the PDC 12 transmits the current position information and the image information as digital signals of about 9.6 kbps to 32 kbps to the telephone terminal 34 of the guide via the radio base station 33 and the public communication line 31. Then, since the decoder 35 decodes these signals, the current position of the visually impaired person 1 is displayed on the first display 36 and the peripheral image of the visually impaired person 1 is displayed on the second display 37.

[0010] Therefore, based on the information obtained from the first and second indicators 36 and 37, the instructor determines, for example, the length of the pedestrian crossing and the signal status displayed on the second indicator 37. Since an appropriate instruction can be given to the visually impaired person 1 via the telephone terminal device 34, the visually impaired person 1 can be safely guided to any destination.

In the above-described embodiment, an example is described in which the visually impaired person 1 is called from the guide, but the guide may be called from the visually impaired person. By using the memory function and the one-touch dial function, even a visually impaired person can easily operate.

As described above, since the visually impaired person guiding system according to the present invention functions, the visually impaired person can safely reach any destination without attending a healthy person and without remembering the directions. Therefore, it is possible to greatly reduce the burden on the attendant and the visually impaired person.

[0013]

As described above, the present invention can safely guide a visually impaired person to an arbitrary destination simply by having the visually impaired person carry a wireless terminal device having a built-in GPS receiving function and a digital camera. It is very effective in realizing a visually impaired person guidance system that can do.
