PDA system, method and device with automatic next turn page

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;
• wherein the PDA processes travel along the route and provides location data to the display;
• 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 to display motion of the PDA on the course through the decision point, and wherein the overlay screen includes cartographic data accurately depicting a geographic detail of the decision point;
• and
• wherein the PDA is adapted to remove insignificant detail from the geographic detail at the decision point-based on a set of criteria.

A navigation aid method for negotiating decision points along a route, comprising:

• detecting when a personal digital assistant (PDA) is approaching a decision point in a route;
• calculating the PDA's current travel speed and position;
• on the PDA, providing to a 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 to display 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.

A personal digital assistant (PDA) system for negotiating a decision point along a route, comprising:

• a server having a processor and 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;
• and
• wherein the server includes executable instructions stored thereon, the processor operable on the executable instructions to—
• process travel along the route and provide location data,
• recognize an approaching decision point in the route, and provide an overlay screen adapted to display a preview of a decision point including a highlighted portion indicating a course to follow through the decision point, and the overlay screen to display motion of the PDA on the course through the decision point, and wherein the overlay screen includes cartographic data accurately depicting a geographic detail of the decision point;
• and
• wherein insignificant detail is removed from the geographic detail at the decision point based on a set of criteria.

An personal digital assistant (PDA) with an automatic next turn page, comprising:

• a calendar function;
• an address book function;
• a processor;
• a memory adapted to communicate to the processor, 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 adapted 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 provides to the display a presently displayed screen adapted to highlight at least a portion of the route and display motion of the PDA on 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 the presently displayed screen, such that at least a portion of the presently displayed screen remains visible, 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 the PDA is adapted to remove insignificant detail from the geographic detail at the decision point based on whether a nearby thoroughfare intersects with a thoroughfare on which the PDA is currently traveling.
