providing location awareness of multiple moving objects in a detail view on large displays

Overview+Detail interfaces can be used to examine the details of complex data while retaining the data’s overall context. Dynamic data introduce challenges for these interfaces, however, as moving objects may exit the detail view, as well as a person’s field of view if they are working at a large interactive surface. To address this “off-view” problem, we propose a new information visualization technique, called Canyon. This technique attaches a small view of an off-view object, including some surrounding context, to the external boundary of the detail view. The area between the detail view and the region containing the off-view object is virtually “folded” to conserve space.
