Navigation system and method
First Claim
1. A road map display apparatus comprising:
- a display device;
means for storing road map data therein;
means for generating and displaying a nonscaled, linearly compressed pictographic view of roads on said display device based on said road map data; and
an input device coupled to said means for generating and displaying a pictographic view of said roads, said input device configured to provide input that is used to determine in part what road map data is used in generating said pictographic view.

Abstract
A novel mapping paradigm is provided for the visual display of information in the form of an improved navigational aid. Unlike today'"'"'s road maps which use a point-arc-polygon paradigm, the new mapping paradigm uses a compressed linear-pictographic-topological design that typically depicts roads as vertical linear pictograms. Further, the display has a columnar layout, whereby the descriptive elements are grouped together by type, and displayed one above the other in columns. In this manner, the mapping paradigm also serves to increase traveler safety, provide navigation assistance during address-less trips, create valuable advertising space and new promotional opportunities, and dramatically increases the travelers'"'"' communications and entertainment options.

12. A navigation system comprising:
-
a display device; means for storing road map and navigational data therein; a display generator coupled to said means for storing and said display device; a position sensing receiver for receiving signals containing position information and determining a current position of said navigation system; and an input device coupled to said display generator, said input device configured to provide user input to said display generator, wherein said display generator using said user input received from said input device an said current position information generates a nonscaled, linearly compressed pictographic view of a portion of said road map and navigational information on said display. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method of displaying a sequential set of road segments, said sequential set of road segments forming navigational directions to a destination, said method comprising:
-
providing a storage means containing a plurality of road segments; providing a user interface coupled to said storage means, said user interface including an input device, a display generator coupled to said storage means and said input device, and a position sensing receiver for receiving signals containing position information and determining a current position of said user interface obtaining input from said input device; generating a sequential set of road segments selected from said plurality of road segments, said set of road segments being selected based on said input from said input device and said current position of said user interface; and sequentially displaying a nonscaled, linearly compressed pictographic view of said set of road segments in the form of navigational directions. - View Dependent Claims (21, 22, 23, 24)
