Abstract

A method of providing navigational information by a navigation system comprising: determining an uncertainty in a device location; retrieving a mode based on the uncertainty; and providing navigational information processed by the mode for displaying on a device.

Claims

1. A method of providing navigational information by a navigation system comprising:

determining an uncertainty in a device location;

retrieving a mode based on the uncertainty; and

providing navigational information processed according to the mode for displaying on a device.

2. The method of claim 1 further comprising:

receiving a connection for receiving or conveying information with a user;

wherein;

determining the uncertainty includes determining the uncertainty based on a latency in the connection.

3. The method of claim 1 wherein determining the uncertainty includes determining the uncertainty based on a sampling rate of measurement information.

4. The method of claim 1 wherein determining the uncertainty includes determining the uncertainty based on an error size associated with identifying a location.

5. The method of claim 1 wherein retrieving the mode based on the uncertainty includes retrieving the mode based on the uncertainty in the calculated device location information.

6. The method of claim 1 wherein retrieving the mode based on the uncertainty includes retrieving a precise instruction message mode.

7. The method of claim 1 wherein retrieving the mode based on the uncertainty includes retrieving a fuzzy instruction mode.

8. The method of claim 1 wherein retrieving the mode based on the uncertainty includes retrieving a summary instruction mode.

9. The method of claim 1 wherein retrieving the mode based on the uncertainty includes retrieving a selective instruction mode.

10. The method of claim 1 wherein retrieving the mode based on the uncertainty includes retrieving a static instruction mode.
