Method and system for an efficient operating environment in real-time navigation system

摘要

An enhanced operating environment for an Interactive Real-Time Distributed Navigation system is disclosed. In the present invention, an enhanced operating environment is provided by improving input and output techniques in a navigation system. Disclosed are methods for reducing the number of inputs to a navigational system through a wireless device. Improved input methods include methods for entering non-deterministic information to retrieve deterministic information.
In particular, a method is provided for determining a preferred path in a navigation system by using a database of user information comprising historical route information concerning the user.
