Towards the Visualization and Understanding of Diagnoses in a Physical System

off the physical visualization. This could be offered in varying degrees of depth such as contextual help is generally offered. In conclusion, it is essential that diagnostic systems make better use of existing visual aids such as multi-dimensional models and diagnostic network browsers to better serve users. The integration of such tools requires that the physical and abstract representations used in knowledge-based systems be better integrated. It is also important to recognize that there are many classes of users of diagnostic systems. There are developers, domain experts and end users (the technicians). Within each class of user there are varying levels of expertise which translate to specific needs that should be addressed. Finally, explanation is a powerful tool useful for better understanding and visualizing diagnoses. It has thus far been poorly used and is very much the cornerstone of better understanding by users of diagnostic systems.
