Definitions

  • This invention relates to electronic method of reporting on the current position, delivering specific information for the relevant zone, delivering information about public transport in real time, providing information for the blind and visually impaired which will enable them to move from location to location, using their own network of transmitters, without use of satellite navigator and according to the international Classification of (IPC) it is classified as A 61 H 3/06; A 61 F 9/08
  • the technical problem is to make a system of notification and precise locating system for people who cannot see or see very little which will not be based on a system of satellite navigation. Satellite navigation is inaccurate for the needs of people who do not see and will be usable for these persons only in 10 years time when Samsung plans to launch 30 high precision satellites.
  • the technical problem is to make a system of notification which will use its own network of transmitters because the creation of a network of transmitters in the conventional way is too expensive.
  • the technical problem is to make such receivers that will submit information to the end user in such a way that in the zone in which one transmitter delivers information no other transmitter can deliver any information. This means that in one zone there is no other information than exactly one transmitted by the transmitter designated for that zone.
  • the technical problem is to make the transmitters that will have relatively small signal coverage zone and the ability to easily modify the coverage zone of the signal coverage so the blind would have guaranteed security of free movement as long as they are in the zone which is receiving the signal.
  • the technical problem is to find as less aggressive and uncomfortable as possible to inform a blind person about being in the zone where they can hear the voice message.
  • the problem is also that how automatically send this information on entering the zone which is projected for the user to receive this signal.
  • the technical problem is mounting all the necessary mechanical parts into the glasses that end users use in everyday life. From this arises the problem of battery consumption in the glasses as well as the weight of the glasses with all the inside parts.
  • the technical problem is to send the information to the blind person regarding the direction of the building broadcasting the signal and where the front door is and for this information not to be received by voice message nor making specific movements or actions in order to find it out,
  • the technical problem is to effectively and unfailingly inform the blind when they are in front of the zone in which possible potential problem for them lie.
  • Such zones are the stairs, taking the path on which motor vehicles move, all types uneven surfaces that can cause danger for these persons and all locations that are designated as potentially dangerous by an expert.
  • the technical problem is to safely and reliably and without the possibility of error lead a blind person to the nearest public transport stop without having them use anyone's help.
  • the technical problem is to provide blind person with the information on whether they are departing or approaching the public transport stop when moving from one location to another.
  • the technical problem is to provide the information regarding which public transport vehicle is coming to the station at that moment and when the vehicle stops where the front door of that vehicle is.
  • the technical problem is to provide the end user of this system to get information about their position without sending any kind of request for this information.
  • the technical problem is to allow the end user to completely eliminate the submission of information. This characteristic is necessary in case when the user knows the zone and there is no need for additional information.
  • the technical problem is to adequately mark the roads or paths in urban areas where the blind can reliable and freely move and send this information effectively and in a usable way to the blind persons.
  • the technical problem is to allow the end user to reliably know where the front door of the specific facility is.
  • the technical problem is to inform the user when they are at the public transport spot, which is the zone from which they will be able to freely enter the vehicle of public transport.
  • the technical problem is to enable blind persons to find the nearest public transport stop without anyone's assistance moving along safe and effectively signposted roads.
  • the technical problem is to provide information on the type of store or service offered when approaching the building.
  • the technical problem is to make transmitters that can supply all the necessary information and at the same production to have very low manufacturing price. This is essential in order to construct a network of own of transmitters in the real conditions.
  • the technical problem is to provide a simple and reliable input of high-quality voice messages into transmitters and modify them easily when needed.
  • the technical problem is to provide a reliable movement of blind persons from location to location.
  • the technical problem is to make inexpensive transmitter which has its own electric power supply that is essential for the zone into which it is necessary to provide information about the dangers and that have no source of electric power nearby.
  • the technical problem is to provide fast and efficient notification to the blind persons in the event of significant changes in the zone where they move. This is particularly important in the case of works being carried out and changes in the configuration of the terrain in any way that could cause problems and prevent unhindered movement of the blind.
  • the technical problem is to send the necessary information to the blind regarding the manner of movement and possible problems when switching from one location to another.
  • the technical problem is to determine the precise point of reference from which further distance should be measured and in an efficient and faultless way send that information to the blind person. This problem becomes evident when you want to send information in the shape of the path along which one should move or in case when information which includes approximate measurement should be sent.
  • the systems of informing blind people, which use the remote control with the infrared rays for identifying public transport vehicles, are known.
  • the problem is that the remote control has to be turned in the direction of arrival of the bus and the action is performed by hand.
  • the quality of audio signal is bad and poorly understood. Traffic lights which use different sounds for information are aggressive for other pedestrians and produce noise if the traffic lights are near buildings where people live.
  • Satellites are not the solution for the needs of blind and visually impaired people because they are not accurate and cannot deliver precise information about position of person going on foot. They particularly cannot deliver information about facility next to which a blind person walks, which service is offered by this facility and where the entrance door is. They also cannot deliver data about public transport vehicles that arrive on the public transport stop. The problem is- which data about what vehicle should be delivered, to whom they should be delivered and when, without anybody who sent the request for sending data.
  • the main goal of this invention is to make the precise system of information and signalization which would enable smooth and reliable movement of blind and visually impaired persons and delivery of information about facilities in their close proximity without using satellite navigation whereby users can decide about amount and type of information they want to receive.
  • the further goal is to deliver all required information about means of public transport, such as the line number and the direction of movement of the coming vehicle, information on which vehicle stopped at the stop, as well as the exact direction of the entrance door.
  • the further aim is to make signalization which would deliver information to the user when he is in the zone where he can receive the voice message. This signalization would be at the same time used to inform the user about where is the entrance door of the facility from which the voice message comes.
  • the further goal is to place all electronic parts in the glasses and phones, the two things blind persons always have with themselves. These devices can be separated if the user wants it.
  • the further goal is to install in glasses the system for determining the direction electronically, whereby the blind person looks for the source of the signal by turning his head in the direction of the sound in the same way as a person who can see, which is very important for acquiring movements. Furthermore, by using glasses and turning head and body to determine the direction, this person does movements which usually would not be done by him, and they are necessary for normal functioning of muscles in those parts of the body.
  • the further aim is to make a network of transmitters that would send voice or some other information to blind and visually impaired people.
  • the transmitter's price would be very low.
  • Very low price is the one expressed in tens of Euros.
  • the further goal is to make a network of transmitters in such a way to avoid financing by state institutions, and to install most transmitters in the supermarkets, service industries, catering facilities, banks and many other facilities that perform commercial activities, because the invested funds measured in tens of Euros would surely return within a short period of time.
  • the goal of this innovation is to guarantee economic viability of the one who buys it and install these kinds of transmitters. There is no need of writing about the human side of this gesture. It is also important to notice that the loss of image in case someone refuses to install the transmitter is irreparable.

  • the path on which transmitters would be installed would also be the integral part of this complex system of delivering information in micro location of each transmitter.
  • Micro location would be the zone from several meters to about ten meters.
  • the further goal is to deliver information about look of the path on which blind people need to walk to the next transmitter in case the path is not a straight line and if there are any potential problems in the zone of movement of users from respective transmitter to the next transmitter.
  • the transmitter In order to precisely determine the baseline from which instructions from micro transmitters could be applied, it is necessary the transmitter has an installed part that will deliver information to the last user on that position.

Since the user's phone is set to receive all Bluetooth transmitters from our zone and since it is possible to receive only one signal from the Bluetooth transmitter at one place, the phone will connect with the Bluetooth transmitter in that zone. In this way it will get information about a facility, how far it is from the nearest public transport stop and are there any possible complications during movement to the next micro transmitter.

This system of information about the change of directions would be mostly used to make a way towards the public transport stop, meaning it could be ignored if the user has no intention of walking towards public transport stop.
  • the blind person exposes himself to dangers of walking the roads used by motor vehicles. He also does not know what is the right position from where he can reliably and without disturbances come into the public transport vehicle, so on each stop we installed mini transmitter with its own power supply via solar cells, that broadcasts the infrared signal in parallel with the road used by public transport vehicle and in this way it determines the zone in which the blind person should be in order to safely and without disturbances enter the public transport vehicle.
  • the Bluetooth transmitter is installed in the public transport vehicle which delivers information to the blind person about the vehicle when it approaches to the projected distance. Ten meters would be enough from the spot where the public transport vehicle should stop, because it is measured within one minute period which is more than enough to multiple times deliver complete information about the number of the vehicle and its direction of movement. When the vehicle stops, it is necessary to inform the blind person about the vehicle and that would be the definite identity confirmation of the vehicle. During the movement of the vehicle, the blind person will get into the zone in which the vehicle from the entrance door emits the infrared signal at a right angle comparing to the front door. Upon receiving the signal from the entrance door of the vehicle, the blind person will know where the entrance door of the public transport vehicle is, and considering he is already in the zone where he can enter the vehicle without disturbances, he will not have difficulties to do that.
  • This invention can effectively be applied to help blind and visually impaired people, in order to enable movement from one to the next micro zone of our mini transmitters, so they can receive information about the facility they pass by, how far they are from the nearest public transport stop, which way they should move in order to get to the public transport stop, and when they are already at the stop which public transport vehicle arrives at the moment. They will also be able to determine the direction of the entrance door, both of some facilities or public transport vehicles, with the help of the glasses that have electronically installed set. They will also receive information about potential dangers on the paths projected for them, as well as all kinds of information that will appear useful for these people. Having in mind the fact that this is a private network of transmitters that are not connected to each other, it is also possible to deliver information to sighted people.

Abstract

Le système d'envoi d'informations pour des personnes aveugles et malvoyantes est composé d'un mini émetteur de signaux audio qui est utilisé pour fournir le signal audio, d'un émetteur de signaux infrarouges, d'un récepteur de signaux audio et d'un récepteur de signaux infrarouges qui sont intégrés dans les lunettes et disposés de manière à recevoir un signal de la gauche, de la droite et de l'avant. L'émetteur de signaux audio et un émetteur de signaux infrarouges sont dimensionnés de sorte que le signal peut être délivré dans une zone limitée de dix mètres, ce qui pourrait donc créer des micro zones dans lesquelles une personne aveugle obtient des informations spécifiques sur la zone ainsi que des instructions sur le déplacement vers les prochaines micro zones. Les micro zones sont caractérisées en ce que, dans une micro zone, il y a un seul signal provenant du groupe d'émetteurs et une personne aveugle n'a pas besoin d'effectuer une action quelconque pour obtenir des informations sur la micro zone dans laquelle elle se trouve actuellement. Selon le même principe, les informations affichées sur les véhicules de transport public seraient délivrées avec une différence qui est que la micro zone serait mobile et que l'utilisateur recevant les signaux serait statique.
