Navigation application with adaptive display of graphical directional indicators

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 to a second location. The data for each juncture comprises a set of angles at which roads leave the juncture. The navigation application includes a juncture simplifier for simplifying the angles for the received junctures. The navigation application includes an arrow generator for generating at least two different representations of the simplified juncture. The representations are for use in displaying navigation information describing a maneuver to perform at the juncture during the route. The navigation application includes an arrow selector for selecting one of the different representations of the simplified juncture for display according to a context in which the representation will be displayed.

1. A non-transitory machine readable medium storing a navigation application for execution by at least one processing unit of a device, the navigation application comprising:
an interface for receiving data describing junctures along a route from a first location to a second location, wherein the data for each juncture comprises a set of angles at which roads leave the juncture; a juncture simplifier for simplifying the set of angles of each juncture based on the received data describing the juncture; an arrow generator for generating at least two different representations of a same maneuver at each simplified juncture while navigating the route; and an arrow selector for selecting, by the at least one processing unit, one of the two different representations to display the maneuver based on a context in which the maneuver will be displayed.
