PDA system, method and device with automatic next turn page
First Claim
1. A personal digital assistant (PDA) with an automatic next turn page, comprising:
- a calender function;
an address book function;
a processor operable to communicate to a memory, the memory having cartographic data and a route to a desired destination stored therein, the cartographic data including data indicative of thoroughfares of a plurality of types;
a display operable to communicate with the processor and the memory and capable of displaying the cartographic data;
wherein the PDA processes travel along the route;
wherein the PDA recognizes when the PDA is approaching a decision point in the route and provides to the display an overlay screen on top of any presently displayed screen, the overlay screen adapted to display a preview of the decision point including a highlighted portion indicating a course to follow through the decision point, and the overlay screen displays motion of the PDA on the course through the decision point; and
wherein insignificant detail is removed from the overlay screen at the decision point based on a set of criteria.

Abstract
PDA systems, devices and methods are provided for improved navigational route planning. The PDA provides more understandable, accurate and timely information for negotiating a decision point along a route. The PDA includes a processor operable to communicate with a memory. The memory has cartographic data and a route to a desired destination stored therein. The cartographic data includes data indicative of thoroughfares of a plurality of types. A display is provided which is adapted to communicate with the processor and the memory and which is capable of displaying the cartographic data. The PDA processes travel along the route. The PDA recognizes when the device is approaching a decision point in the route and provides to the display an overlay screen on top of any presently displayed screen, the overlay screen adapted to display a preview of a decision point.

10. A personal digital assistant (PDA) with an automatic next turn page, comprising:
-
a calendar function;
an address book function;
a processor operably coupled to a memory, the memory having cartographic data and a route stored therein to navigate from a beginning position to a desired destination, the cartographic data including data indicative of thoroughfares of a plurality of types, the route including a number of decision points;
a display in communication with the processor and the memory and capable of displaying the cartographic data, the route to the desired destination, and the PDA'"'"'s position;
