Abstract
(EN)
A client navigation system establishes a wireless connection to a navigation server on a computer network. The client requests a route by uploading start and stop specifications. The server calculates an optimal route based on real-time data available on the network. The optimal route is downloaded to the client in a natural language description and is independent from the local mapping database software on the client and includes a plain text description for each link. The client reconstructs the optimal route which is displayed on the client navigation system. A user-interface that anticipates data being entered by users minimizes the data-entry process. The current GPS position is used to set the clock on the navigation system in the client. Maps are scrolled on a display so that a representation of the automobile is always pointing to the right or to the left for additional look-ahead space on certain display systems. A dialed number is used to query a local database for providing local time information and the telephone automatically displays the current local time.

L'invention concerne un système de navigation client qui établit une connexion sans fil avec un serveur de navigation dans un réseau informatique. Le client demande une route en téléchargeant vers l'amont des spécifications de départ et d'arrêt. Le serveur calcule une route optimale en fonction des données en temps réel disponibles dans le réseau. Cette route optimale est téléchargée en aval chez le client sous forme d'une description en langage naturel indépendante du logiciel de base de donnée de cartographie locale du client et comprend une description en texte clair de chaque embranchement. Le client reconstitue la route optimale, qui est affichée sur le système de navigation client. Une interface utilisateur anticipe les données entrées par les utilisateurs de manière à réduire le processus d'introduction de données. L'horloge du système de navigation du client est réglée sur la position GPS courante. Les cartes défilent sur l'écran de telle manière qu'une représentation de l'automobile est toujours orientée vers la droite ou vers la gauche ce qui permet la présentation d'un plus grand intervalle d'anticipation sur certains dispositifs d'affichage. Un numéro d'appel permet d'appeler une base de données locale afin d'obtenir une information relative au temps local et le téléphone affiche automatique l'heure locale en vigueur.
