Abstract
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 sytstem through a wireless device. Improved input methods include methods for entering non-deterministic information to retrieve deterministic information. Also disclosed are improved output techniques including methods for pacing navigational prompts provided by a navigation system. The invention is applicable to text, graphics or audible navigation systems.
