The evolution of HCI technology is a coevolution of HCI tasks and HCI artifacts: A task implicitly sets requirements for the development of artifacts to support; an artifact suggests possibilities and introduces constraints that often radically redefine the task for which the artifact was originally developed. [...] This dynamic relation, the task-artifact cycle, circumscribes the development activities of human-computer interaction

Karrer, Anthony and Scacchi, Walt (1990): Requirements for an Extensible Object-Oriented Tree/Graph Editor. In: Hudson, Scott E. (ed.) Proceedings of the 3rd annual ACM SIGGRAPH symposium on User interface software and technology October 03 - 05, 1990, Snowbird, Utah, United States. pp. 84-91.

Software engineers use graphs to represent many types of information. This paper describes a tool which is used to rapidly extend base classes to create graph editors as a user-interface to these information domains. This paper also presents requirements for extensible graph editors. These requirements establish a basis of comparison for extensible graph editors. An object-oriented programming language and an object-oriented user interface toolkit provide a great degree of flexibility for creating graph editors. Users create instances of a graph editor by specifying global and local functionality. Global functionality takes the form of graph layout algorithms, user interaction, and interaction with other tools. Local functionality is the description of the meaning and pictorial representation of nodes and arcs. As such, this paper describes a number of example graph editors that have been developed with these mechanisms which satisfy the requirements.
