Enabling A User To Return To Default Contextual Location Or Previously Viewed Location On A Magnified Canvas

Disclosed is a method and system for enabling a user to return to a default contextual location or a set of previously viewed locations in a canvas by activating a zoom slider control. Here, the magnification level stays the same when the user activates the zoom slider control to intelligently reposition the canvas.

In accordance with an exemplary embodiment, the system enables a view of a user to quickly return to a default contextual location or a set of previously viewed areas by activating a zoom slider control. The user double clicks on the zoom slider control for repositioning the view to a default location such as the center of the canvas or a localized problem area. Further, the user is provided with an option to specify user's preferences for repositioning the view to previously visited locations. When the user double clicks on the zoom slider control, the view gets repositioned to the user's prior locations in reverse sequential order.

Consider an exemplary scenario depicted in FIG. 1, wherein a user is accessing a canvas (or a map).

In accordance with the system disclosed herein, a zoom slider is used to magnify the canvas. The canvas is magnified to a magnification level for displaying the center of the canvas or a localized problem area to the user. Thereafter, the user pans the

canvas to a different location. When the user wishes to reposition the view to a preferred location, the user double clicks the zoom slider control. In response to the double clicking of the zoom slider control, the view of the canvas is repositioned to a preferred location of the user, while remaining at the same magnification level.

As shown in FIG. 1, the entire canvas viewed in (a) is magnified to display a localized problem area in (b) that is also the center of the canvas for the user. Thereafter, the user moves away from the localized problem area, towards the green circles at the far left of the canvas as displayed in (c). When the user wishes to reposition the view to the center of the canvas, or the localized problem area, the user double clicks the zoom slider control as displayed in (d). In response to the user double clicking the zoom slider control, the view on the canvas is repositioned to the default location, which is the localized problem area, while still remaining at the magnification level as displayed in FIG. 2.
