1. A personal digital assistant (PDA), comprising:
- a calendar function;
an address book function;
a processor; and
a memory adapted to communicate with the processor, wherein the processor and memory are adapted to cooperate to access a sequence of maneuvers associated with a sequence of route segments and provide route guidance that accounts for insignificant route segments, including route guidance that modifies a maneuver associated with an insignificant route segment, and are further adapted to provide the calendar function and the address book function.

Abstract
PDA systems, devices and methods are provided to account for insignificant route segments to enhance a route guidance experience. A PDA is provided according to one aspect. The PDA includes a processor and a memory adapted to communicate with the processor. The processor and memory are adapted to cooperate to provide route guidance that accounts for insignificant route segments. According to various embodiments, insignificant route segments are accounted for by nullifying and/or modifying route guidance maneuvers associated with the insignificant route segments. Other aspects are provided herein.

8. A personal digital assistant (PDA) method for guidance, comprising:
-
identifying a sequence of maneuvers associated with a sequence of route segments; determining, in conjunction with a PDA, whether a route segment in the sequence of route segments is significant or insignificant; upon determining that the route segment is significant, providing route guidance to the PDA for a maneuver associated with the significant route segment; and upon determining that the route segment is insignificant, accounting for the insignificant route segment prior to providing route guidance to the PDA for a maneuver associated with the insignificant route segment, wherein accounting for insignificant route segments includes nullifying the maneuver associated with some insignificant route segments and modifying the maneuver associated with other insignificant route segments. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A personal digital assistant (PDA) method for guidance, comprising:
-
accessing a sequence of maneuvers associated with a sequence of route segments; determining, in conjunction with a PDA, whether a route segment from the sequence of route segments is significant or insignificant, including; determining whether the route segment has a name; determining whether the route segment has a length less than a predetermined distance; determining whether the route segment has a length less than a length of a successive route segment; and determining whether a route guidance maneuver for the route segment and a route guidance maneuver for a successive route segment qualify for nullification or modification; upon determining that the route segment is significant, providing route guidance to the PDA for a maneuver associated with the significant route segment; and upon determining that the route segment is insignificant, accounting for the insignificant route segment prior to providing route guidance for a maneuver associated with the insignificant route segment, wherein accounting for the insignificant route segment includes modifying the maneuver associated with the insignificant route segment.

19. A personal digital assistant (PDA) method for guidance, comprising:
-
accessing a sequence of maneuvers associated with a sequence of route segments; determining, in conjunction with a PDA, whether a route segment in the sequence of route segments is significant or insignificant, wherein determining whether a route segment is significant or insignificant includes; determining whether the route segment has a name; upon determining that the route segment does not have a name, determining whether the route segment has a length less than a predetermined distance; upon determining that the route segment has a length less than a predetermined distance, determining whether the route segment has a length less than a length of a successive route segment; and upon determining that the route segment has a length less than a length of a successive route segment, determining whether a route guidance maneuver for the route segment and a route guidance maneuver for a successive route segment qualify for nullification or modification; upon determining that the route segment is significant, providing route guidance for a maneuver associated with the significant route segment; and upon determining that the route segment is insignificant, accounting for the insignificant route segment prior to providing route guidance for a maneuver associated with the insignificant route segment, wherein accounting for the insignificant route segment includes modifying a first maneuver and nullifying a second maneuver associated with the insignificant route segment.
