Abstract

La présente invention concerne un système de navigation GPS qui est destiné à une personne aveugle et qui utilise une RFID et une boussole électronique, l'objet de l'invention étant de guider la personne aveugle vers la destination prévue de la personne sans l'aide d'une autre personne. À cet effet, la présente invention comprend : une étiquette RFID qui comprend un code RFID ; un lecteur RFID qui est installé dans la canne de l'utilisateur et reçoit un identificateur unique de l'étiquette RFID ; une base de données qui stocke des données de carte, l'ID unique de l'étiquette RFID, une valeur de coordonnées GPS correspondant à l'ID unique, et des fichiers d'informations d'emplacement environnant ; une unité d'émission et de réception qui émet le code RFID à la base de données et reçoit des données d'itinéraire de carte, une valeur GPS de l'étiquette RFID sur l'itinéraire, et les fichiers d'informations d'emplacement environnant ; une unité de stockage qui stocke des données et des fichiers téléchargés ; une unité de commande qui vérifie si l'utilisateur s'écarte de l'itinéraire, détermine la distance et la direction vers une étiquette RFID proche, utilise la boussole électronique (un capteur géomagnétique) pour déterminer la direction à laquelle fait actuellement face l'utilisateur, corrige le cap de l'utilisateur en comparant le cap avec les données d'itinéraire de carte, et notifie à l'utilisateur les informations d'emplacement environnante ; une unité de traitement audio qui traite des informations vocales ; et un GPS qui est utilisé pour déterminer l'emplacement de l'étiquette RFID et si l'utilisateur se déplace le long d'un itinéraire donné. La présente invention comprend les fonctions consistant à : corriger des erreurs dans la valeur GPS en utilisant la RFID ; corriger les erreurs d'estimation du relèvement (est, ouest, sud et nord) du GPS en utilisant la boussole électronique (le capteur géomagnétique) ; et guider le lecteur RFID, qui est fixé à la canne de l'utilisateur, le plus près possible de l'étiquette RFID afin de notifier à l'utilisateur les informations d'emplacement environnant.
