Systems and methods for a PDA with improved route calculation capabilities
First Claim
1. A personal digital assistant (PDA) with route calculation capabilities, comprising:
- a calendar function;
an address book function;
a processor operable to communicate with a memory, the memory having cartographic data and a desired destination, the cartographic data including data indicative of thoroughfares of a plurality of types;
a display operable to communicate with the processor and the memory, the display capable of displaying the cartographic data;
wherein the PDA is operable to calculate a route to navigate to the desired destination; and
wherein the PDA is operable to adjust a starting point for the route calculation to an appropriate location such that the PDA is on (a correct course) the route at a time when the route calculation is completed.

Abstract
Systems, devices and methods are provided for an improved navigational route planning device which provides more understandable, accurate and timely route calculation capabilities. A PDA with route calculation capabilities includes a processor connected to a memory. The memory includes cartographic data and a desired destination, the cartographic data including data indicative of thoroughfares of a plurality of types. A display is connected to the processor and is capable of displaying the cartographic data. The PDA is adapted to calculate a route to navigate to the desired destination. And, the PDA is adapted to adjust a starting point for the route calculation to an appropriate location such that the PDA is on the route at a time when the route calculation is completed. The PDA processes travel along the route, recognizes when the PDA has deviated from the route, and calculates a new route to navigate to the desired destination.

15. A navigation method for performing a route calculation on a PDA, comprising:
-
determining a travel speed of the PDA;
estimating a calculation time for processing a first route of navigation from a first location of the PDA to a desired destination; and
selecting a starting point for the first route of navigation based on the determined travel speed of the PDA and the estimated calculation time for processing the first route of navigation. - View Dependent Claims (16, 17, 18, 19, 20)

21. A system, comprising:
-
a mass data storage adapted to store navigation data;
a server having a processor and memory, wherein the server is adapted to communicate with the mass data storage; and
a multifunction device adapted to communicate with and retrieve navigation data from the server via a communication channel, wherein the multifunction device includes;
a calendar function;
an address book function;
a processor operably coupled to a memory and a display, 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;
wherein the system processes the multifunction device'"'"'s travel along the route;
wherein the system recognizes when the device has deviated from the route and is adapted to calculate a new route to navigate the device to the desired destination using an exchange of data, via the communication channel, between the server, the mass storage device and the multifunction device; and
wherein the system is adapted to adjust a starting point for the new route calculation to an appropriate location such that the device is on the new route at a time when the route calculation is completed. - View Dependent Claims (22, 23, 24, 25, 26)
