title	On visual design thinking: the via kids of architecture
source	Design Studies 15 (2), pp. 158-174
summary	Designers invariably use imagery to generate new form combinations which they represent through sketching. But they also do the reverse: they sketch to generate images of forms in their minds. Common belief regards such activity as non-rational. In contrast, we assert that interactive imagery through sketching is a rational mode of reasoning, characterized by systematic exchanges between conceptual and figural arguments. Cognitive science, strongly dominated by a linguistic paradigm, has yet to recognize the paramount role of visual reasoning in many instances of problem solving; and in design tool-making, computational and otherwise, we must learn to optimize rather than bypass intuitive visuality.

title	Intuitive Analysis as Mediator Between Concept and Representation
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Representation in Computer Aided Architectural Design Systems has to date largely focused on the presentation of the end product of design activity, namely the ultimate built form. In thisrespect, 3-dimensional representations traditionally associated with CAAD visualization have relied heavily upon verisimilitude for their efficacy, and have therefore necessitated high levels of dimensional accuracy together with exhaustive description, both of which are absent in the early stages of design formulation. This paper investigates the desired structure of a computational design formulation system which is based, not upon the representation (or presentation) of ultimate form, but instead upon the representation of architectonic ideas resident in the designer's mind, which are central to the organization and generation of proposals. These ideas are of two kinds: conceptual generators, both poetic and architectonic, and the organizational parti or schematic proposals, which embody them. The representation of ideas rather than end form has two primaryobjectives. Firstly, it enables the designer's realization and clarification of concept or parti, and secondly, but most importantly, it enables the designer to critically assess these ideas in relation tothe contextual situation and brief. The computational representation must be structured in a manner which supports the designer's intuitive critical assessment of it, to in turn induce a modification and development of the initial design ideas. Repeated transformation, representation, and intuitive analysis, can then continue in a cyclical manner until an end proposal is achieved. Intuitive analysis, which becomes the mediator between idea and representation, is itself computationally supported by the dual methodologies of comparative and modal superimposition. Superimposition of previous with present representation (either in two or three dimensions)enhances comparative assessment of design developments. Modal analysis, on the other hand, facilitates the superimposition of schematic representations of modes of design thought (circulationpattern with volumetric arrangement, say) in order to intuitively assess their interaction or conflict.

title	The Algebra of Shapes
source	Carnegie Mellon University, Departement of Architecture
summary	This thesis investigates a new representation scheme for geometric modeling, based on an algebraic model for shapes and formalized using a boundary representation. The algebraic model is mathematically uniform for shapes of all kinds and provides a natural and intuitive framework for mixed-dimensional shapes. The corresponding maximal element representation is essential to the concept of shape emergence. The representation scheme particularly supports computational design as a generative process of search or exploration. This thesis begins with a treatment of the algebraic and geometric properties of shapes and gives a formal and complete definition of the maximal element representation for n-dimensional shapes in a k-dimensional space (n ? k). Efficient algorithms are presented for the algebraic operations of sum, product, difference and symmetric difference on shapes of plane and volume segments. An exploration of related research in shape grammars, computational design and construction simulation, illustrates the potential of this representation scheme, while an agenda for future research depicts its present shortcomings.

title	A Hypermedia Tutoring for Multimedia Tasks
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Using a computer or a software package involves procedural knowledge, or knowledge of a series of instructions. When a user recognizes the appropriate computer commands (the method) in acertain application, it is assumed that the user is capable of doing a computer-related or computeraided task. Based on this assumption, the current project explores methods of developing a computer tutoring system to convey know-how efficiently. The purpose of the project is to make novices familiar with machines and with techniques of handling multimedia for presenting design concepts. A teaching tool is designed that combines images, sounds, and movements to create an effective learning environment. The tool is a hypermedia system consisting of different software and hardware components implemented in the HyperCard. How to manipulate different media will be taught by means of cross-references, graphic display, text explanations, and background music. Hopefully, this project will suggest some useful methods for teaching CAD to novice computer users.

title	Urban Gis - The Application of the Information Technologies to Urban Management
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Many cities in the UK and indeed throughout the developed world are characterised by the all too familiar symptoms of urban blight caused by insensitive intervention in the environment. The common denominator within this class of problem is the lack of a coordinated, integrated approach to the planning, design and maintenance of our cities. The cycle of development and redevelopment calls for input from a diverse range of disciplines relating to architecture, civilengineering, transport engineering, and the management of city utilities. This lack of a common up datable information base renders access to a global view of the city difficult, if not impossible.This problem has provided the motivation to move towards an integrated philosophy regarding information collection, collation and dissemination. The impetus is provided primarily through theincreasing complexity of urban management but also through central governments policy to progress towards decentralisation of services. Fiscal pressure to increase efficiency, lower manpower resources and arrive at speedier judgements all point to an increasing reliance on the information technologies. Current work at ABACUS within Strathclyde University addresses research whose objective is to identify, and then prototype, a relevant urban information system. It is proposed that by attributing a geometrical framework with those physical quantities thatare relevant to the formal and functional evaluation of the urban environment, the means of evaluating the qualities and quantities of the buildings aswell as the social and economic prospects may be realised.

title	Where No Mind Has Gone Before: Ontological Design for Virtual Spaces Papers
source	Proceedings of the ECHT'94 European Conference on Hypermedia Technologies 1994 pp. 206-216
summary	Hypermedia designers have tried to move beyond the directed graph concept, which defines hypermedia structures as aggregations of nodes and links. A substantial body of work attempts to describe hypertexts in terms of extended or global spaces. According to this approach, nodes and links acquire meaning in relation to the space in which they are deployed. Some theory of space thus becomes essential for any advance in hypermedia design; but the type of space implied by electronic information systems, from hyperdocuments to "consensual hallucinations," requires careful analysis. Familiar metaphors drawn from physics, architecture, and everyday experience have only limited descriptive or explanatory value for this type of space. As theorists of virtual reality point out, new information systems demand an internal rather than an external perspective. This shift demands a more sophisticated approach to hypermedia space, one that accounts both for stable design properties (architectonic space) and for unforeseen outcomes, or what Winograd and Flores call "breakdowns." Following Wexelblat in cyberspace theory and Dillon, McKnight, and Richardson in hypermedia theory, we call the domain of these outcomes semantic space. In two thought experiments, or brief exercises in interface design, we attempt to reconcile these divergent notions of space within the conceptual system of hypermedia.

title	Some Phenomena of seeing shapes in design
source	Design Studies, v 16, n 3, pp. 367-385
summary	This paper is a look at some of the pyschological results that suggest how shape emergence manifest itself in the human mind. The first interesting result goes back to top down expectation guiding recognition. Some experimental suggest that it is easier (quicker) to recognize shapes which we have some alternate mental familiarity. (I.E. verbal, structural descriptions). So if we can easily say a shape then we can easily discern it as an emergent shape. The paper then goes on to discuss the definition of emergent subshapes and gives various authors definitions of what makes up and emergent shape. One interesting classification is the difference between explicit and implicit emergent shapes made by Mitchell. This difference amounts to a fine line between imagination and emergence. The results of an experiment between experienced and in-experienced designers is discussed. The results suggest that experienced designers are able to find more emergent shape than non experienced designers. From these results and from the opinions of others, the author goes on to specify 3 phenomena related to emergent recognition. The first is as above that it is easier to see shapes with which we are familiar. Second from this, the harder shapes are found after the initial period. Third, from the first two, time is required to find more subshapes. The author then searches for an explanation of this phenomena. He suggests that the underlying cause is related to an experience person having a lower threshold of what it is to be a member of a shape. When seeing an L shape the experienced design is likely to consider it also a square, because his requirement for the set of features which must be present for some object to be a considered a square is a smaller set than the inexperienced. While the author suggests that this is a phenomena it is actually an hypothesis. An alternate hypothesis may be that top down inhibitions effect the bottom up performance of the inexperienced design more because of different representation.
