MULTIMODAL PERCEPTUAL REPRESENTATIONS AND DESIGN PROBLEM SOLVING B. CHANDRASEKARAN
Abstract:
Abstract. This paper places external visual representations in design in the larger contexts of perceptual representations and problem solving in general. We outline a framework that brings together external and internal representations, and conceptual, perceptual and kinesthetic modalities. We make use of a task analysis of design to identify the roles these various representations might play in design. 1. Setting the Context Visual representations are the lifeblood of the activity of design- not only are diagrams, sketches, and CAD drawings used during design in domains that are intrinsically spatial, but they are also used extensively in design domains that are not intrinsically spatial, such as software design and planning. In the latter domains, spatial relations are analogs for some domain relations: connectivity, nearness in some abstract space, relations with the same metric properties as spatial relations, and so on. Of course, from one point of view, the pervasiveness of visual representations in design is just a special case of
