Abstract

A method for displaying labels on a map image on a computerized mobile device includes displaying a map image and at least one label in a first orientation on a display unit, the at least one label associated with at least one feature on the map image and disposed at a first location. The method also includes changing the map image to a second orientation different from the first orientation and displacing the at least one label from the first location to a second location to maintain the association between the label and the feature. The method further includes displaying the map image in the second orientation on the display unit, and displaying the at least one label in the first orientation and disposed at the second location. A device programmed to carry out the method is also provided.
