Method and system for an efficient operating environment in a real-time navigation system
First Claim
1. A method for determining a preferred path using non-deterministic input to a navigation system comprising the steps of:
- maintaining a database of location information;
receiving non-deterministic input from a user, identifying a first location for the user based on said database of location information, said non-deterministic input and one or more pre-determined criteria;
determining a preferred path from said first location to a second location, said step of determining based on said location information relating to said first location.

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.

11. A method for labeling a user'"'"'s present location in a navigation system comprising the steps of:
-
requesting a first user location;
receiving a first a position signal from said user;
identifying said first user location based on said position signal;
receiving a first label from said user;
assigning said first label to the first user location;
storing the first label in a database of location information; and
retrieving said first user location using said first label. - View Dependent Claims (12, 13)
