Technique for effective navigation based on user preferences

摘要

A navigation device utilizes stored user profiles to navigate a user who may be driving in a vehicle on foot, or in other mode of transportation. Each user profile corresponds to one of the user's personae. For example the user business profile corresponding to the user's business persona may be different from the user personal profile corresponding to the user's personal persona. The navigation device provides the user with a navigated route, together with information concerning the favorite facilities and events surrounding the navigated route. which satisfy the preferences in a selected user profile. Blockages may also be established using the device to avoid selected areas, or to block transmission of selected information.
