Abstract
A system, method, and apparatus for displaying map information in a cardinal direction-up setting. In one embodiment, map information is displayed on a display terminal. Next, an icon representing the position and heading of an item with respect to the displayed map information is placed over the displayed map information. In the present invention, the map information is displayed in a cardinal direction-up setting corresponding to the heading of the icon. Thus, if the heading of the icon is directed in a substantially eastern direction, the map information is displayed in an east-up orientation. The present invention further includes hysteresis logic which regulates when a different cardinal direction is oriented upward.
