Computational Support to Aesthetics in Industrial Design
Abstract. Computational support is rarely available for aesthetic concept generation in industrial design. The reason for limited computational support to aesthetic design seems to be the lack of formal theory or methodology for ‘Design for Aesthetics’ (DFAe) paradigm. Aesthetic concept generation involves complex interplay of the cognitive processes and experiential (tacit) knowledge in the shape generation and appreciation, which is quite tough to externalize in a formal model. Current CAD/CAS tools lack the consideration of the cognitive process in shape definition. The present work aims to focus on the development of a formal model for DFAe, and based on this model; implement a knowledge based tool, which can actively support the aesthetic design process by capturing and externalizing the tacit design knowledge. The proposed model is based on four axioms derived from various domains. These are: the axiom of objects; the axiom of human knowledge; the axiom of cognitive structuring; and the axiom of cognitive transformation. These axioms lead to the development of two important models; the aesthetic design complex and action grammar. The aesthetic design complex is derived from a more general and abstract model called general design complex derived from these axioms. The action grammar provides an alternative mechanism of shape description, taking the cognitive process in consideration. In this grammar, the cognitive actions leading to different shape characteristics are implemented as grammar rules.
