Patent

CA 2385171

An Interactive Real-Time Distributed Navigation system is disclosed. In the present invention a user's location is determined by generating a position signal at the user's location. Through wireless communication between the user and distributed navigation servers, the user is presented with a list of candidate locations (102). The user's choice from the candidate list (102) are then used by the navigation servers to obtain an accurate measurement of the user's location. Having established a user's location, the system proceeds to provide navigational prompts (106) to the user to reach a final destination.

La présente invention concerne un système de navigation répartie en temps réel. La position de l'utilisateur est déterminée par un signal de position produit à l'emplacement de l'utilisateur. On présente à l'utilisateur une liste de positions candidates (102) via une communication sans fil entre l'utilisateur et des serveurs de navigation répartis. Le choix de l'utilisateur effectué à partir de la liste d'emplacements candidats (102) est ensuite utilisé par les serveurs de navigation pour obtenir une mesure précise de la position de l'utilisateur. Lorsque la position de l'utilisateur est définie, le système fournit des invites de navigation à l'utilisateur pour qu'il arrive à la destination finale.
