A method for providing visual continuity when performing a zooming or panning operation with a graphical map shown on display screen of a computing platform. When a user of the computing platform operates the user interface thereof to perform a zooming or panning operation, a first map view of a first geographic area is replaced with a second map view of a second geographic area, such that at least a portion of the first and second geographic areas overlap. In order to provide visual continuity, a transition view is shown on the display screen of the computing platform between the showing of the first map view and the showing of the second map view. The transition view is shown for several seconds immediately after the user operates the user interface to perform the zooming or panning operation. The transition view shows either the first map view or the second map view. The transition view also includes a boundary line that is overlaid on the map view being shown. The boundary line is located on the map view used for the transition view to show the border of the portion of the other map view which is visible in the map view used for the transition view. The method for providing visual continuity is particularly useful for in-vehicle navigation systems or hand-held devices with small display screens. The method can also be applied to text windows.
