Abstract:
The present invention is a computer-implemented system for providing guidance information to aid a user in traveling along an off-road route. This system assumes that the route has already been determined. Also, it is assumed that the user's position and orientation can be determined, for example using existing techniques such as the global positioning system (GPS). The present invention uses a Look-Ahead-Point Finder (100) to find a point, which we refer to as a look-ahead point, located on the route ahead of the user's current location. A Guidance Message Constructor (102) and a Guidance Presenter (106) are used to present the user with guidance information directing him towards the look-ahead point. If the user is already headed towards the look-ahead point, then a Turn Analyzer (108) is used to search the route in order to find the next turn location. If the user is found to be nearing a turn, then the Guidance Message Constructor (102) and the Guidance Presenter (106) are used to give the user information about the turn including its distance and direction.
