Title
(EN) A COMPUTER-IMPLEMENTED METHOD, WEARABLE DEVICE, NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM, COMPUTER PROGRAM AND SYSTEM FOR ASSISTING THE MOVEMENT OF A VISUALLY IMPAIRED USER
(FR) PROCÉDÉ MIS EN ŒUVRE PAR ORDINATEUR, DISPOSITIF POUVANT ÊTRE PORTÉ SUR SOI, SUPPORT DE STOCKAGE LISIBLE PAR ORDINATEUR NON TRANSITOIRE, PROGRAMME INFORMATIQUE ET SYSTÈME D'AIDE AU MOUVEMENT D'UN UTILISATEUR AYANT UNE DÉFICIENCE VISUELLE
Abstract
(EN) In a first aspect of the invention, it is claimed a computer-implemented method for assisting the movement of a visually impaired user by means of a wearable device, comprising the following steps: 5 S1- Acquiring data from the environment of the visually impaired user, S2- Fusing the acquired data, creating, repeatedly updating of a Live Map, S3- Determining, repeatedly updating and storing, of at least one navigation path together with associated navigation guiding instructions for the visually impaired user to navigate from the current position of the visually impaired user to a point of interest, repeatedly 10 selecting one preferred navigation path from the at least one navigation path, and repeatedly sending to the visually impaired user the preferred navigation path, together with associated navigation guiding instructions. S4- Guiding the visually impaired user along the preferred navigation path, by using guiding modes for transmitting each associated navigation guiding instruction, 15 comprising haptic and/or auditory cues. The invention details how the steps S2, S3 and S4 are carried out and also details the content of the Live Map. Said Live Map comprises data from the sensors regarding objects and living beings, relationships between the objects and the living beings and different types of areas: walkable area, non-walkable area and conditional walkable area, 20 In a second aspect of the invention, it is claimed a wearable device for assisting the movement of a visually impaired user, configured to apply the steps of the method.
(FR) Selon un premier aspect de l'invention, il est revendiqué un procédé, mis en œuvre par ordinateur, d'aide au mouvement d'un utilisateur ayant une déficience visuelle au moyen d'un dispositif pouvant être porté sur soi, comprenant les étapes suivantes consistant : S1 - à acquérir des données de l'environnement de l'utilisateur ayant une déficience visuelle, S2 - à fusionner les données acquises, à créer, à mettre à jour de manière répétée une carte en direct, S3 - à déterminer, à mettre à jour et à stocker de manière répétée, au moins un trajet de navigation conjointement avec des instructions de guidage de navigation associées pour l'utilisateur ayant une déficience visuelle afin de naviguer à partir de la position actuelle de l'utilisateur ayant une déficience visuelle vers un point d'intérêt, à sélectionner de manière répétée un trajet de navigation préféré à partir du ou des trajets de navigation, et à envoyer de manière répétée à l'utilisateur ayant une déficience visuelle le trajet de navigation préféré, conjointement avec des instructions de guidage de navigation associées. S4 - à guider l'utilisateur ayant une déficience visuelle le long du trajet de navigation préféré, à l'aide de modes de guidage permettant de transmettre chaque instruction de guidage de navigation associée, comprenant des repères haptiques et/ou auditifs. L'invention détaille la manière dont les étapes S2, S3 et S4 sont effectuées et détaille également le contenu de la carte en direct. Ladite carte en direct comprend des données provenant des capteurs concernant des objets et des êtres vivants, des relations entre les objets et les êtres vivants et différents types de zones : zone propice à la marche, zone non propice à la marche et zone propice à la marche conditionnelle. Selon un second aspect de l'invention, il est revendiqué un dispositif pouvant être porté sur soi d'aide au mouvement d'un utilisateur ayant une déficience visuelle, configuré pour appliquer les étapes du procédé.
