Let’s Look at Style: Visual and Spatial Representation and Reasoning in Design

Abstract. This chapter explores the perception and modeling of style in design re-lating to visuo-spatial representation and reasoning. We approach this subject via cognitive and contextual considerations significant to the role of style during de-signing. A designer’s ability to represent and reason about design artifacts visually and spatially allows meaningful ‘chunks ’ of design information to be utilized rela-tive to the designer’s task and context. Central to cognitive and contextual notions of style are two issues, namely the level of semantic interpretation, and the com-parative method’s degree of contextual sensitivity. This compound problem re-quires some explicit and cognitively plausible ordering principle and adaptive measure capable of allowing for dependencies in reasoning about similarities. This chapter first investigates the perception of style in relation to these modeling re-quirements before demonstrating and testing their implementation. We then dis-cuss style in relation to design tasks and how they can be supported via the classi-fication and retrieval of designs from large databases of visuo-spatial information. 1
