1. A mobile electronic device comprising:
- a display device;
a memory operable to store one or more modules; and
a processing system operable to execute the one or more modules to;
anticipate a future path of the mobile electronic device;
cause navigation information to be displayed by the display device, the navigation information including a roadway graphic configured to represent a roadway and a speed limit indicator graphic configured to indicate a speed limit associated with the roadway; and
temporarily alter a display attribute of the navigation information to furnish a notification of a change in the indicated speed limit based on the anticipated future path;
wherein the navigation information further includes a map and the display attribute comprises a hue of at least one of the map or the speed limit indicator graphic, andwherein the hue of the display attribute is momentarily changed from a default color to a second color when the speed limit decreases, to a third color when the speed limit increases, and to a fourth color when speed limit information is not available for the roadway.

Abstract
Techniques are described that may be implemented in a mobile electronic device providing navigation functionality to furnish a notification that the indicated speed limit of a roadway being traversed has changed. In an implementation, the display of the mobile electronic device is configured to display navigation information including a roadway graphic representing a roadway being traversed by the mobile electronic device and a speed limit indicator graphic for indicating the speed limit associated with the roadway. When a change in the indicated speed limit is encountered, an attribute of the navigation information is temporarily altered to provide a notification of the change.

12. A mobile electronic device comprising:
-
a memory operable to store map data comprising speed limit information that includes speed limits associated with a roadway being traversed; a display device operable to display navigation information generated using the map data, the navigation information configured to include a roadway graphic that represents the roadway being traversed and a speed limit indicator graphic that indicates a speed limit associated with the roadway; a position-determining module operable to receive satellite navigation signals and determine a geographic position of the portable electronic device using the received satellite navigation signals; a processing system operable to execute at least one module to anticipate a future path of the mobile electronic device, detect a change in the speed limit associated with the roadway by comparing the determined geographic position of the mobile electronic device with the speed limit information and change the indicated speed limit, the at least one module configured to temporarily alter a display attribute of the navigation information to furnish a notification of a change in the indicated speed limit based on the anticipated future path; and wherein the navigation information further includes a map and the display attribute comprises a hue of at least one of the map or the speed limit indicator graphic, and wherein the hue of the display attribute is momentarily changed from a default color to a second color when the speed limit decreases, to a third color when the speed limit increases, and to a fourth color when speed limit information is not available for the roadway. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method comprising:
-
causing navigation information to be displayed on a display of a mobile electronic device, the navigation information including a roadway graphic representing a roadway being traversed by the mobile electronic device and a speed limit indicator graphic for indicating the speed limit associated with the roadway; causing a future path of the mobile electronic device to be anticipated; causing the indicated speed limit to be changed in response to a change in the speed limit of the roadway; and causing an attribute of the navigation information to be temporarily altered to furnish a notification of the change in the indicated speed limit based on the anticipated future path; wherein the navigation information further includes a map and the display attribute comprises a hue of at least one of the map or the speed limit indicator graphic, and wherein the hue of the display attribute is momentarily changed from a default color to a second color when the speed limit decreases, to a third color when the speed limit increases, and to a fourth color when speed limit information is not available for the roadway. - View Dependent Claims (19)
