Plastic visual tools
in Proceedings of the 1992 IEEE Workshop on Visual Languages, Conference paper (text)
A plastic visual system is presented, based on a hierarchy of environments that users can define, refine and use. In each environment, experts build visual expressions specifying activities to be performed at a lower level. The mechanisms exploited to obtain these features are based on uncoupling the organisation of the interface from the definition of its actual components, objects managed by the applications from their views and views from the components of the interface which present them.
