Abstract
Description

La présente invention concerne un dispositif permettant aux personnes mal ou non voyantes de sentir les distances entre elles et les obstacles, ainsi que les variations d'hauteur du sol, et ce en déplacement ou non. The present invention relates to a device enabling visually impaired or blind people to feel the distances between them and the obstacles, as well as the variations in height from the ground, whether on the move or not.
La plupart des personnes mal ou non voyantes utilisent une canne blanche tenue à la main, qu'elles balayent devant elles afin de repérer les obstacles. Most people who are blind or partially sighted use a hand-held white cane, which they sweep in front of them to identify obstacles.
Des systèmes plus sophistiqués commencent à voir le jour, mais ils nécessitent l'utilisation la main, non disponible pour autre chose, et génèrent des sons pour donner l'information, ce qui gène la perception auditive de l'environnement. More sophisticated systems are starting to emerge, but they require the use of the hand, which is not available for anything else, and generate sounds to give information, which impairs the auditory perception of the environment.
Le dispositif selon l'invention laisse les mains libres, ne nuit pas à la capacité auditive, et permet d'explorer un volume plus vaste et ce plus de précision et de rapidité. The device according to the invention leaves the hands free, does not harm the hearing capacity, and makes it possible to explore a larger volume and this more precision and speed.
Le dispositif selon l'invention comporte un ou plusieurs transducteurs à ultrason (1,2, 3) reliés à un circuit électronique (4) qui génère les impulsions d'émission, traite les signaux de réception, et transmet à l'utilisateur les informations de distances entre lui et les obstacles, par l'intermédiaire d'indicateurs sensitifs (5,6, 7), ou selon les variantes, par des vibreurs, par des sons ou des électrode. Une batterie rechargeable fournie l'énergie (8). The device according to the invention comprises one or more ultrasonic transducers (1,2, 3) connected to an electronic circuit (4) which generates the transmission pulses, processes the reception signals, and transmits the information to the user. of distances between it and the obstacles, by means of sensitive indicators (5,6, 7), or according to the variants, by vibrators, by sounds or by electrode. A rechargeable battery provides energy (8).
L'ensemble du dispositif peut-être fixé autour du crâne (Fig A, B), soit par un bandeau muni de boîtiers soit intégré dans un couvre-chef, ce qui permet à l'utilisateur, par un mouvement de la tête, d'augmenter les informations sur son environnement, tout en gardant les mains libres. The whole device can be fixed around the skull (Fig A, B), either by a strip fitted with housings or integrated in a headgear, which allows the user, by a movement of the head, to '' increase information about their environment, while keeping their hands free.
Le dispositif selon l'invention peut comporter trois transducteurs à ultrason : le premier (1) explore l'espace devant à légèrement à gauche, le deuxième (2) devant légèrement à droite, avec une zone de chevauchement, ils permettent ainsi de donner des informations en stéréo , le The device according to the invention can comprise three ultrasonic transducers: the first (1) explores the space in front of slightly to the left, the second (2) in front of slightly to the right, with an overlapping zone, they thus make it possible to give information in stereo, the
<Desc/Clms Page number 2><Desc / Clms Page number 2>
troisième (3) regard juste devant les pieds de l'utilisateur et donne la distance relative du sol, ainsi il indique les variations d'hauteur du terrain : bordure de trottoir, muret, escalier etc. third (3) look just in front of the user's feet and give the relative distance from the ground, so it indicates the variations in height of the ground: curb, low wall, staircase etc.
Ces informations pourront être transmises à l'utilisateur par des indicateurs sensitifs articulés de manière à épouser la forme de la zone de la tête ou du corps où ils sont placés, ils ont un fonctionnement proche des afficheurs braille et de celui des bar-graphes . This information can be transmitted to the user by sensitive indicators articulated so as to match the shape of the head or body area where they are placed, they operate close to Braille displays and that of bar graphs.
Les indicateurs sensitifs peuvent être placés comme suit : Un de chaque cotés du crane horizontalement, celui de gauche (5) donnant les informations venant de devant à gauche, celui de droite (6) celle de devant à droite, un troisième (7) verticalement au-dessus du front indique les dénivellations du sol. The sensitive indicators can be placed as follows: One on each side of the skull horizontally, the one on the left (5) giving the information coming from front to left, the one on the right (6) the one from front to right, a third (7) vertically above the forehead indicates the unevenness of the ground.
Selon les variantes le dispositif peut comporter moins de traducteurs et donc donner moins d'informations. Depending on the variants, the device may include fewer translators and therefore give less information.
Il peut aussi être équipé de transducteurs montés sur des servomoteurs de manière à scruter l'espace avec plus de précisions. It can also be equipped with transducers mounted on servomotors so as to scan the space with more precision.
Il peut transmettre les informations à l'utilisateur soit par des indicateurs sensitifs, soit par des sons, soit par des vibreurs, soit par des électrodes. It can transmit information to the user either by sensitive indicators, or by sounds, or by vibrators, or by electrodes.
Les dessins annexés illustrent l'invention : La figure A en vue de coté et la figure B en vue de face montrent le dispositif selon l'invention sur la tète d'un utilisateur, en (1) et (2) les transducteurs regardant devant, en (3) le transducteur scrutant le sol, en (4) le circuit électronique, en (5) et (6) les indicateurs sensitif horizontaux, en (7) l'indicateur vertical et en (8) la batterie rechargeable. The accompanying drawings illustrate the invention: Figure A in side view and Figure B in front view show the device according to the invention on the head of a user, in (1) and (2) the transducers looking in front , in (3) the transducer scanning the ground, in (4) the electronic circuit, in (5) and (6) the horizontal sensitive indicators, in (7) the vertical indicator and in (8) the rechargeable battery.
La figure C montre en vue de coté et la figure D en vue de dessus les volumes explorés par le dispositif.Figure C shows a side view and Figure D a top view of the volumes explored by the device.
