JPH1124619A - Voice guide system of transmission type of radio wave and infrared ray or the like - Google Patents

Abstract

PROBLEM TO BE SOLVED: To narrow the range of a literal information supply to a receiver against visually handicapped persons or the like, and to obtain automatically a guide information in a facility or the like, by establishing a sensor-sensitive area within a small range, and by transmitting a recorded voice guide by operating a transmitter in case that a person enters within a prescribed distance. SOLUTION: When a visually handicapped person walks, carrying a receiver 22, in a facility, an infrared-ray sensor 24 built in a transmitter 21 perceives that he enters an area within a prescribed distance, then a base sound (sound of a 'bell-ring' insect) is produced and a transmission of a guide information is started from an electronic-sound speaker 25. He can acknowledge the guide information by the sound of a 'bell-ring' insect, and also he can hear the guide information as a voice by the receiver 22. When the visually handicapped person goes out of the sensitive area of the infrared-ray sensor 24, the transmission and the operation of the electronic sound are stopped. Besides, even when a person except a visually handicapped person enters the sensitive area of the infrared-ray sensor 24 of the transmitter 22, a transmission of the guide information and a production of the base sound are operated, but he can hear only the sound of the 'bell-ring' insect, so the sound is not offensive to his ears.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to install a plurality of transmitters in indoor / outdoor facilities used by visually impaired persons, etc., and to provide guidance information transmitted from each transmitter to the visually impaired persons by receivers. This is a transmission type voice guidance system such as a radio wave and infrared ray which receive guidance information to obtain guidance information. Furthermore, when FM waves are used as transmission waves, character information can be received by a receiver simply by adding the FM character multiplexing method, and character guidance can be provided not only to voice guidance to visually impaired persons but also to hearing impaired persons. It is a guidance system that can be provided.

[0002]

2. Description of the Related Art As a system of this type, there is a speaker voice guidance device. In order to allow only visually impaired persons to specify the operation, a sensor is built in a white stick, or a transmitter is carried by a visually impaired person to transmit radio waves. The mainstream is to activate voice guidance. In addition, there is a device that uses AM / FM waves to provide voice guidance with a portable receiver, but there is no device that uses electronic sound or the like serving as a transmission base point. Further, a system for transmitting and receiving text information in a large area is FM text broadcasting. However, there is no system for transmitting and receiving text information in a very small range and providing guidance around the transmitter using a base point such as a blinking lamp.

[0003]

The conventional speaker voice guidance system has a great deal of inconvenience caused by speaker voices to a hearing person such as a worker in an indoor facility or the like, and has been widely used outdoors such as in a street or an entrance. Further, in the case of using the AM / FM wave, the transmission area is too large, and it is not necessary to clarify the transmission base point by an electronic sound or the like. Therefore, only information about the entire transmission area is provided. The present invention has been made in view of the above problems, and an object of the present invention is to provide audio guidance at a receiver for visually impaired persons or the like in a troublesome place in speaker audio guidance such as indoor facilities.

[0004] Few facilities are equipped with devices such as voice guidance for visually impaired persons. However, although there are many opportunities for visually impaired persons to use facilities without voice guidance or the like, there is no system that can be installed temporarily and provide guidance information. Therefore, if a battery-powered, small and lightweight transmitter is used, this system does not require any construction, so that it can be temporarily installed and operated at the time of an event or the like, making it easier to use the facility.

[0005] The range of providing text information to a receiver for the hearing impaired or the like is extremely small, and guidance information in the facility or the like is automatically obtained, so that various facilities can be easily used. It is to provide a system.

[0006]

SUMMARY OF THE INVENTION A voice guidance system for transmitting radio waves, infrared rays, etc., sets a sensor sensing area to a small range, and when a person enters within a predetermined distance, a transmitter operates to reduce a voice guidance recorded. Send to range. By receiving the voice guidance information at the receiver, the visually impaired person can automatically obtain the voice guidance information.

[0007] By transmitting the guide information by radio waves and infrared rays and generating a base sound such as an electronic sound and a synthesized voice at the same time, a visually impaired person or the like is informed that the guide information can be received from the transmitter. Since the reference point of the guide information from the transmitter is indicated, the transmission base point of the guide information becomes clear, and detailed guidance around the transmitter becomes possible. In addition, a hearing person such as a worker cannot hear the voice guidance, but only hears a base sound such as an electronic sound, and is not harsh.

[0008] By using a battery type or a solar cell type as the power source of the transmitter, this system can be installed and operated in any facility or place. Also, since no construction is involved, temporary installation and operation of facilities at the time of an event or the like becomes possible.

In this system, when the transmission method is the FM teletext broadcasting system, not only voice but also text information can be received by carrying a receiver compatible with the FM teletext broadcasting. That is, in addition to visually impaired persons, hearing impaired persons and the like can be operated as a guidance system, and can be smoothly operated in facilities used by various persons with disabilities.

[0010]

When a sensor in the transmitter detects a person entering the area, a base sound such as an electronic sound or a synthesized voice is activated, and at the same time, guidance information recorded in advance by radio waves or infrared rays is transmitted. The visually impaired receives the guidance information with the receiver carried and obtains the information as voice guidance with earphones or the like. Of course, hearing people can also use it. If the power is kept on when the user has the receiver, the guide information transmitted from the transmitter can be automatically obtained when the transmitter approaches the predetermined distance range. A person who does not need the guidance information can hear only the base sound, and a normal hearing person such as a worker can hear only the base sound, which is hardly annoying.

[0011] The multi-power system and the absence of construction require
Since it can be retrofitted to any facility and can be used for temporary installation such as an event, it provides a lot of favorable environments for the visually impaired and the like. Also, F
By adding the M character multiplexing method, character information can be provided to a hearing-impaired person or the like using the same system.
