Method and apparatus for displaying real-time visual information on an automobile pervasive computing client
First Claim
1. A display method operative in a pervasive computing client having a graphical display, comprising the steps of:
- displaying a map on the graphical display;
plotting a user'"'"'s current position on the map; and
as the user'"'"'s current position approaches a given physical landmark, displaying a photographic image of the landmark, the photographic image showing real-time conditions, to assist the user'"'"'s navigation.

Abstract
A navigation system, preferably for use in a vehicle. The system includes a processor, and a graphical display for displaying map information. As the vehicle approaches a given location, e.g., an intersection, a visual image of the location is retrieved and displayed on the graphical display. In one embodiment, the visual image is a photograph of the location that is displayed in a pop-up window on the display screen. If desired, additional graphic images or text are superimposed on or associated with the image to facilitate navigation. Thus, for example, if the user were approaching an intersection, the invention displays a still photograph of the intersection, together with an arrow overlaid thereupon to illustrate that the user should make a given turn.
