A Prototyping Environment for Dynamic Data Visualisation

This paper describes the model underlying a user interface prototyping system which is designed to support the creation of multi-user, interactive database visualisations. The context of the work is the automation of an air traffic control system; we are concerned with the user interface to the in-flight database. The model is based on active display agents which interact in real-time with the database. The model separates the selection of entities for display, the entity representations and the way in which these representations are presented to specific controllers. The advantages of this model are that it allows multiple database views to be updated concurrently, it allows views to be shared by users at different workstations and it allows a high degree of end-user tailorability.
