NAVIGATION APPLICATION WITH ADAPTIVE INSTRUCTION TEXT

摘要

Some embodiments provide a navigation application. The navigation application includes an interface for receiving data describing junctures along a route from a first location on a map to a second location on the map. The data for each juncture includes a set of angles at which roads leave the juncture. The navigation application includes a juncture decoder for synthesizing, from the juncture data, instruction elements for each juncture that describe different aspects of a maneuver to be performed at the juncture. The navigation application includes an instruction generator for generating at least two different instruction sets for a maneuver by combining one or more of the instruction elements for the juncture at which the maneuver is to be performed. The navigation application includes an instruction retriever for selecting one of the different instruction sets for the maneuver according to a context in which the instruction set will be displayed.

1. A mobile device comprising:
a set of processing units for executing instructions; a non-transitory machine readable medium storing a navigation application comprising sets of instructions for:
receiving data describing junctures along a route from a first location on a map to a second location on the map;synthesizing, from the juncture data, instruction elements for each juncture that describe different aspects of a maneuver to be performed at the juncture;identifying an upcoming maneuver for which a navigation instruction has to be provided;generating at least two different instruction sets for the maneuver by combining one or more of the instruction elements for the juncture at which the maneuver is to be performed; andselecting one of the different instruction sets to provide the navigation instruction for the maneuver according to a context in which the instruction set will be displayed.
