ABSTRACT:
An electronic navigation device and method, for displaying a visual representation of navigational information in a selected perspective view, includes a processor, a display, a key pad input, a memory, and an antenna. Navigational information, such as way-points in an active route, hazards and landmarks, and the position, direction, and speed of movement of the navigational device, are entered into the processor. The processor determines a trapezoidally-shaped visible region based upon user inputs, clips the navigational information to the visible region, and transforms the navigational information within the visible region to a selected perspective viewing plane. Polygons, representative of highway lanes, are displayed on the display, in the desired perspective view, for each route leg of a route within the visible region. Intersecting route legs, oriented at different angles relative to each other, have rounded ends so as to precisely overlap and illustrate a curve in the "highway lanes" at a turn event way-point. The device and method provide for an at least substantially true perspective view of navigational information, which is updated in real time.
