Abstract
In a data processor controlled display system having three-dimensional objects laid out in a three-dimensional virtual workspace, the objects have associated there with respective collision barriers which are stored with their corresponding objects. Then during navigation via changing the users viewpoint in to the workspace, when this changing viewpoint encounters any collision barrier which is offset from its object by a selected distance D, the viewpoint stops. This distance of the barrier from the object is selected so as to stop the viewpoint at a distance sufficiently removed from its particular object so as to leave the user or viewer with a view of the workscape of sufficient scope to permit the viewer to select a different navigation path or path branch. In accordance with a further aspect of the present invention, the viewpoint is optionally provided with a similar collision barrier.
