Method of providing visual continuity when panning and zooming with a map display
First Claim
1. A method for providing visual continuity when performing a panning operation with a map display on a display screen of a computing platform, the method comprising the steps of:
- displaying a first map view of a first geographic area on the display screen of the computing platform, wherein the first map view is at a first scale;
in response to a user'"'"'s operation of a user interface of the computing platform to perform a panning operation, displaying a second map view of a second geographic area on the display screen of the computing platform, wherein the second map view is at the first scale, and wherein the second geographic area includes a portion of the first geographic area and a portion not in the first geographic area;
during several seconds immediately upon the displaying of the second map view, rendering a boundary line on the second map view, wherein the boundary line corresponds to a border between the portion of the first geographic area shown in the second map view and the portion of the second geographic area not in the first map view; and
after the several seconds, causing the boundary line to disappear.

Abstract
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.

6. A method for providing visual continuity when performing a zooming-out operation with a map display on a display screen of a computing platform, the method comprising the steps of:
-
displaying a first map view of a first geographic area on the display screen of the computing platform, wherein the first map view is at a first scale; in response to a user'"'"'s operation of a user interface of the computing platform to perform a zooming-out operation, displaying a second map view of a second geographic area on the display screen of the computing platform, wherein the second map view is at a second scale which is smaller than the first scale, and wherein the second geographic area includes the first geographic area and a portion not in the first geographic area; during several seconds immediately upon the displaying of the second map view, rendering a boundary line on the second map view, wherein the boundary line corresponds to a border between the first geographic area shown in the second map view and the portion of the second geographic area not in the first map view; and after the several seconds, causing the boundary line to disappear. - View Dependent Claims (7, 8, 9, 10, 11)

12. A method for providing visual continuity when performing a zooming-in operation with a map display on a display screen of a computing platform, the method comprising the steps of:
-
displaying a first map view of a first geographic area on the display screen of the computing platform, wherein the first map view is at a first scale; in response to a user'"'"'s operation of a user interface of the computing platform to perform a first zooming-in operation, displaying a second map view of a second geographic area on the display screen of the computing platform, wherein the second map view is at a second, larger scale, and wherein the first geographic area includes the second geographic area and a portion not in the second geographic area; and during several seconds immediately following the user'"'"'s operation of the user interface of the computing platform to perform the first zooming-in operation, rendering a boundary line on the first map view, wherein the boundary line corresponds to a border between the portion of the first geographic area shown in the second map view and the portion of the first geographic area not in the second map view. - View Dependent Claims (13, 14, 15, 16, 17)
