Abstract

In visual information processing diagrams are frequently used for representing information. In large scale systems this results in very large diagrams and raises the questions of how to best display such diagrams on a computer screen and how to navigate around the diagrams.The aim of this research is to develop a system for automatic navigation of large diagrams. To display the diagram we are using a distortion oriented display technique. This shows the overall structure in outline form, but the particular area of interest in sufficient detail. Our navigation system is based on reasoning and making inferences. By automatic navigation we mean that the focused viewpoint is moved automatically along a navigation path. Using a clue set provided visually by the user the diagram is traversed following some navigation path. We are currently developing a prototype system.
