Abstract

Design space explorers are computer programs that play on an exploration metaphor to support design. They assist designers in creating alternative designs by structuring the process of design creation in a space of alternatives. Subsidiary metaphors relevant to design space explorers are generation, navigation, and reuse. This paper introduces, in two sketches, typed feature structures as a formal system in which a design space explorer and its knowledge level might be implemented. First, informal and abstract properties of typed feature structures suffice to build a sketch of the behavior of a design space explorer. Second, using an example based on single-fronted cottages (a common Australian housing type), we outline the typed feature structure machinery most relevant to design space exploration.
