Abstract

A method and system for interactive real-time distributed navigation employs improved techniques for input and output. The method and system may receive inputs through a wireless device. The operating environment simplifies and reduces these inputs. In some embodiments, the system receives non-deterministic input to generate deterministic information using a number of methods. The system may also employ improved output techniques including methods for pacing navigational prompts provided by a navigation system, and methods of providing navigational information to a number of users. The method and system are applicable to text, graphics or audible navigation systems.
