Abstract

L'invention concerne un dispositif (100) de navigation qui comporte une partie recherche (102) d'itinéraire, et une partie guidage (101) pour assurer un guidage sur l'itinéraire recherché. Lorsqu'il devient difficile pour un corps mobile de se déplacer suivant l'itinéraire de guidage, une partie commande (103) fait en sorte que la partie recherche (102) recherche un autre itinéraire, différent de l'itinéaire de guidage. Une partie notification (104) notifie l'autre itinéraire recherché. Une fois l'itinéraire notifié, une partie entrée (105) reçoit une entrée de commande de l'utilisateur établissant s'il y a lieu de passer de l'itinéraire affiché à l'autre itinéraire. Lorsque la partie entrée (105) reçoit une commande d'entrée ne permettant pas de passer de l'itinéaire affiché à l'autre itinéraire, la partie commande (103) provoque l'affichage d'un autre itinéraire, recherché ultérieurement par la partie recherche (102) selon le contenu de données d'entrée de commande.
