Description
INSTALLATION DE GUIDAGE POUR NON-VOYANTS
La présente invention se rapporte à une installation de guidage pour non-voyants.GUIDANCE SYSTEM FOR THE BLIND
The present invention relates to a guidance installation for the blind.
A moins qu'il ne dispose d'un chien d'aveugle, il n'est pas possible actuellement à un non-voyant de se guider seul sur un trajet en ville. Unless he has a guide dog, it is currently not possible for a blind person to guide himself on a journey in town.
L'invention vise à résoudre cette difficulté en permettant à un non-voyant de se guider facilement, tout en étant informé de la nature des choses rencontrées, sur un trajet prédéterminé, pouvant être par exemple un trajet de promenade. Pour obtenir ce résultat, la voie piétonne est équipée d'un graphique au sol consistant en une ou plusieurs lignes tracées sur toute la longueur du trajet à effectuer et dans lesquelles sont intercalées, à des endroits prédéterminés du trajet, des informations codées en code-barres. Le non-voyant est équipé d'un lecteur tel qu'une canne lectrice ainsi que d'un dispositif récepteur avec écouteur d'oreille. Ce lecteur comporte un dispositif électronique apte à lire l'information (ligne(s) et codes) inscrite sur le sol, à la transformer en un signal à fréquence audible, et à la transmettre à un moyen d'écoute par le non-voyant. The invention aims to resolve this difficulty by allowing a blind person to be guided easily, while being informed of the nature of the things encountered, on a predetermined route, which may for example be a walking route. To achieve this result, the pedestrian lane is equipped with a ground graphic consisting of one or more lines drawn over the entire length of the journey to be made and in which information coded in code- are inserted at predetermined places in the journey. bars. The blind person is equipped with a reader such as a reading stick as well as a receiving device with an earphone. This reader includes an electronic device capable of reading the information (line (s) and codes) written on the ground, transforming it into an audible frequency signal, and transmitting it to a means of listening by the blind person. .
De toute façon, l'invention sera bien comprise, et ses avantages et autres caractéristiques apparaîtront, au cours de la description suivante d'un exemple non limitatif de réalisation de cette installation de guidage pour non-voyants, en référence au dessin schématique annexé dans lequel
Figure 1 est une vue d'ensemble de cette installation
Figure 2 en est un schéma électronique sous forme de schéma-blocs.In any case, the invention will be well understood, and its advantages and other characteristics will appear, during the following description of a nonlimiting example of embodiment of this guide installation for the blind, with reference to the schematic drawing appended in which
Figure 1 is an overview of this installation
Figure 2 is an electronic diagram in the form of block diagram.
En se reportant à l'ensemble des figures, une ligne 1 de couleur claire est tracée sur le sol le long du trajet à parcourir par le non-voyant. A des endroits déterminés sont intercalées sur cette ligne 1 des indications codées en code-barres, tel que 2. Cette indication codée est une information adéquate, telle que
- à votre droite, rue..., ou
- à un mètre, feu rouge, ou
- à un mètre, escalier montant, ou
- station de taxis, etc....Referring to all of the figures, a line 1 of light color is drawn on the ground along the path to be traveled by the blind. Barcode coded indications are interspersed on this line 1, such as 2. This coded indication is adequate information, such as
- on your right, rue ..., or
- at one meter, red light, or
- at one meter, ascending staircase, or
- taxi stand, etc ...
Le non-voyant tient une canne lectrice 3 qu'il anime tout en marchant d'un mouvement alternatif perpendiculaire à la ligne 1. Il porte un écouteur d'oreille 4 qui est relié à la canne 3 par une transmission à ondes infrarouges 5. A chaque passage de la canne sur la ligne 1, il reçoît un top sonore qui lui indique la présence de cette ligne, et lui assure donc la direction recherchée. Arrivé au niveau du code-barres 2, la canne lit ce code lors de son mouvement transversal, et le transmet sous forme d'information vocale à l'écouteur d'oreille 4. The blind person holds a reading rod 3 which he animates while walking in an alternating movement perpendicular to the line 1. He wears an earpiece 4 which is connected to the rod 3 by an infrared wave transmission 5. Each time the rod is passed over line 1, it receives a sound signal which indicates the presence of this line, and therefore provides it with the desired direction. When it reaches barcode 2, the rod reads this code during its transverse movement, and transmits it in the form of voice information to the earpiece 4.
La canne 3 est creuse et elle contient non seulement une pile ou une batterie rechargeable, mais encore un lecteur de code 6, suivi (figure 2) d'un pré-amplificateur 7 qui pilote un synthétiseur vocal 8. Ce dernier pilote, par l'intermédiaire d'un modulateur 9 également inclus dans la canne 3, un émetteur à infrarouges 10 fixé sur celle-ci. The rod 3 is hollow and it contains not only a battery or a rechargeable battery, but also a code reader 6, followed (FIG. 2) by a pre-amplifier 7 which controls a voice synthesizer 8. This latter controls, by the 'Via a modulator 9 also included in the rod 3, an infrared transmitter 10 fixed thereon.
Derrière l'oreille 11 du non-voyant est fixé un petit appareil, ressemblant à un appareil pour malentendants, et qui comporte un récepteur-démodulateur 12 pour ondes infrarouges, suivi d'un amplificateur basse fréquence 13 et de l'écouteur 4. Behind the ear of the blind 11 is fixed a small device, resembling a device for the hearing impaired, and which comprises a receiver-demodulator 12 for infrared waves, followed by a low frequency amplifier 13 and the earpiece 4.
L'invention n'est bien entendu pas limitée à l'exemple de réalisation qui vient d'être décrit. On peut par exemple prévoir à chaque feu rouge, ou autre obstacle du trajet, un émetteur de signal infrarouge modulé par une information vocale que le non-voyant reçoit alors grâce au récepteur-démodulateur 12 et à l'écouteur 4-associé. On peut remplacer la ligne unique 1 par plusieurs lignes parallèles. La réalisation peut être simplifiée, par exemple en n'utilisant pas de liaison infrarouge, mais une simple liaison par fil entre le synthétiseur vocal 8, suivi bien sûr d'un amplificateur de mise à niveau, et de l'écouteur d'oreille 4. On peut aussi se passer totalement de cet écouteur 4 en faisant suivre le synthétiseur vocal 8 d'un amplificateur basse fréquence alimentant un haut-parleur miniaturisé, ce qui a peut-être pour inconvénient d'être moins discret, mais est d'utilisation plus confortable. La canne lectrice peut être remplacée par un boîtier, du genre sac à main, avec lecteur laser incorporé. The invention is of course not limited to the embodiment which has just been described. We can for example provide at each red light, or other obstacle of the journey, an infrared signal transmitter modulated by voice information that the blind then receives thanks to the receiver-demodulator 12 and the 4-associated earpiece. The single line 1 can be replaced by several parallel lines. The realization can be simplified, for example by not using an infrared link, but a simple wire connection between the voice synthesizer 8, followed of course by an upgrade amplifier, and the earpiece 4 We can also do without this earphone 4 by following the voice synthesizer 8 with a low frequency amplifier powering a miniature speaker, which may have the disadvantage of being less discreet, but is of use More comfortable. The reader can be replaced by a case, such as a handbag, with a built-in laser reader.
