title Engaging Intuitive Visual Thinking in Urban Design Modelling: A Real-Time Hypothesis
doi https://doi.org/10.52842/conf.acadia.1988.087

summary This paper will present prototypical software being used in the teaching of urban design to students and for use by professionals in the early stages of a project. The system is intended to support a heuristic approach to design. That is, it supports a process of refining ideas and understandings through a process of trial and error. The support or aid to design comes in the form of a didactic real-time programme. Its power lies in its ability to provide instantaneous response to operations on the data that can allow one to develop threedimensional spatial ideas in an intuitively driven manner. This condition appears to occur for both novice and expert computer operators.

The presentation will present our experience to-date in using conventional computer graphic tools to represent design ideas and contrast it with a video demonstration of our prototypical dynamic urban design modelling software for the Silicon Graphics IRIS computers.

title Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 247-264.
summary The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called “gingerbread houses”, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title Logic Models of Design
source Pitman, London
summary This monograph places design in a theoretical context which applies developments in knowledge-based systems, logic programming and planning to design. It addresses two important design issues: the interpretation of designs, which concerns the discovery of implicit design attributes, a key activity in design evaluation that can be modelled by deductive inference in logic programming; and the process of generation, whereby a design description is produced which exhibits these implicit design attributes. Implicit attributes can be seen as analogous to the semantic content of natural language utterances. The work presented here is mainly concerned with design generation, and an operational model of design is investigated in which operations on processes are treated in a similar way to operations on form. It is argued that there are advantages in representing control knowledge as rules in a design system, and that logic is an effective medium for this purpose. This is demonstrated by means of programs developed in Prolog and C using the example of spatial layout in buildings. Primarily, this book is directed at those in artificial intelligence (AI) involved in logic programming, planning and expert systems. However, since AI techniques are finding widespread application in industry, the use of an architectural design example makes this work relevant to architects, designers, engineers and developers of intelligent architectural design software.

summary This book constitutes both a theoretical and a technical exploration into modelling design tasks in logic. It provides a framework for describing design processes based on logic, achieved primarily by gathering together various strands evident in theories of reasoning, problem solving, design and knowledge engineering. The book demonstrates the applicability of logic programming and knowledge-based techniques to design, particularly in the area of controlling generative systems. The design task by which this is demonstrated is spatial layout, though the issues reach further than this one application

title Geometrical Fundamentals for Design and Visualization of Spatial Objects
source CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 171-178
summary Every architectural object is a 3-dimensional entity of the human environment, haptically tangible and optically visible. During the architectural process of planning every object should be designed as a body and should be visualized in pictures. Thus the parts of construction get an order in space and the steps of construction get an order in time. The ideal planning object is a simulated anticipation of the real building object, which is to be performed later on. The possibility to relate the planning object immediately to the building object relies on the fact that they both have the same "geometry" This means: both can be described in the same geometric manner. Creating and visualizing spatial objects is based on geometrical fundamentals. Theoretical knowledge and practical control of these fundamentals is essential for the faultless construction and the realistic presentation of architectural objects. Therefore they have to be taught and learned thoroughly in the course of an architectural education. Geometrical design includes the forming of object- models (geometry of body boundaries), the structuring of object-hierarchies (geometry of body combinations) and the colouring of objects. Geometrical visualization includes controlling the processes of motion, of the bodies (when moving objects) and of the center of observation (when moving subjects) as well as the representation of 3-dimensional objects in 2- dimensional pictures and sequences of pictures. All these activities of architects are instances of geometrical information processing. They can be performed with the aid of computers. As for the computer this requires suitable hardware and software, as for the architect it requires suitable knowledge and capabilities to be able to talk about and to recall the perceivable objects and processes of the design with logic abstracts (language of geometry). In contrast to logical, numerical and textual informations the geometric informations concerning spatial objects are of much higher complexity. Usually these complexes of information are absorbed, processed and transmitted by the architect in a perceptive manner. The computer support in the field of geometry assumes that the processing of perceptions of the human consciousness can be converted by the computer as a framework of logical relations. Computer aided construction and representation require both suited devices for haptical and optical communication and suitable programs in particular.

summary This paper compares the musical and architectural languages exploring the similarities between works related to Twelve-tone music and Descontruction. To do this, first looks at Opus 27 by Anton Webern whose goal was to explore the spatiality in the context of sound perception by using a topology based on a square matrix of twelve rows and columns. Next, compares these procedures to those adopted by Peter Eisenman to design the conceptual model Guardiola House (1988), demonstrating the affinity between spatial and temporal constructions in the works of these two authors.

summary This volume contains the papers in the robotics and processes areas from the Third International Conference on Artificial Intelligence in Engineering. Robotics has the potential to change the physical face of engineering and has no counterpart in traditional engineering. It requires the integration of numerous disparate aspects of engineering. There is a fundamental requirement for geometric and spatial reasoning of a qualitative kind. A variety of other processes in engineering are being examined through the artificial intelligence lens. The material collected under the process rubric demonstrates both the benefits and potential of utilizing this approach. The papers are presented under the following headings: Robotics; Geometric and Spatial Reasoning; Interpretation Processes; Reasoning Processes; Planning and Scheduling Processes; Interfaces

summary According to AI techniques, spatial reasoning is seen in construction as generation and solving of goals involving a spatial representation model of buildings defining a rich taxonomy of parts and elements, and spatial relationships between these parts and elements. The authors define spatial representation model and spatial relationship from previous experiments in architect knowledge representation and automated surveying. The aim is to enable very abstract and short descriptions of building component assemblies, from designers at drawing-boards or from workers on sites, which can be processed and transformed in basic geometrical properties

title Segregation of Form, Color, Movement, and Depth : Anatomy, Physiology, and Perception
source Science. May, 1988. vol. 240: pp. 740-750 : ill. some col. includes bibliography
summary Anatomical and physiological observations in monkeys indicate that the primate visual system consists of several separate and independent subdivisions that analyze different aspects of the same retinal image: cells in cortical visual areas 1 and 2 and higher visual areas are segregated into three interdigitating subdivisions that differ in their selectivity for color, stereopsis, movement, and orientation. The pathways selective for form and color seem to be derived mainly from the parvocellular geniculate subdivisions, the depth- and movement-selective components from the magnocellular. At lower levels, in the retina and in the geniculate, cells in these two subdivisions differ in their color selectivity, contrast sensitivity, temporal properties, and spatial resolution. These major differences in the properties of cells at lower levels in each of the subdivisions led to the prediction that different visual functions, such as color, depth, movement, and form perception, should exhibit corresponding differences. Human perceptual experiments are remarkably consistent with these predictions. Moreover, perceptual experiments can be designed to ask which subdivisions of the system are responsible for particular visual abilities, such as figure/ground discrimination or perception of depth from perspective or relative movement-functions that might be difficult to deduce from single-cell response properties

title Some Metaphysical Considerations Raised by the Computer-Generated Electronic Environment
doi https://doi.org/10.52842/conf.acadia.1988.059
source Computing in Design Education [ACADIA Conference Proceedings] Ann Arbor (Michigan / USA) 28-30 October 1988, pp. 59-70
summary The effects of the computer on the designer are profound, and affect design methodology and habitation. The computer-aided designer experiences within the electronic environment a freedom from certain important constraints of real-world modelling of physical reality. Electronic configurations are not bound by the constructional, material, or structural constraints operating in the physical world. This freedom is liberating, in that the imagination is given a powerful tool with which to develop external representations of ideal environments. But there is also the potential of destructive tendencies. Is the increasing sophistication of external tools of the imagination at the expense of the ability of the individual to master the internal imagination - are we externalizing at the price of inner vision? There is also the possibility of greater alienation from the physical world. We loose the tactile sensitivity, and the spatial and structural intuition with which we draw and make physical models. These are essential parts of the design of the physical environment.

We are left on the horns of a dilemma. The rapid response and exciting images of the computergenerated video environment suggest we are entering an era when architecture itself becomes electronic. The physical built-form recedes in importance, and may even become redundant. But we must also ask: Are we entering a post-computer age? Will we realize the potential profundity of our innate human biocomputers - to the point where we renounce the hard technology of the material for the soft technology of consciousness?

title Logical Models for Rule-based CAAD
source CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 107-116
summary The aim of this paper is to present the basic results of a theoretic approach to represent architectural individual forms in CAD systems. From the point of view of design methodology and problem solving these descriptions might be conceived' as parts of possible environments satisfying the laws of some design theory in logical sense. This paper describes results in a series of logical studies towards rule and knowledge based systems for design automation. The effective use of programming languages and computers as design aids in architecture presupposes certain capabilities to articulate built environment logically. The use of graphic languages in the description of environmental items e.g. buildings might be theoretically mastered by formal production systems including linguistic, geometric, and spatio-material generation. The combination of the power of formal mechanisms and logical individual calculus offers suitable framework to generate arbitrary e.g. free spatial compositions as types or unique solutions. In this frame it is natural to represent in a coherent way very complex hierarchical parsing of buildings in explicit form as needed in computer implementations. In order to simulate real design work the individual configurations of possible built forms should be designed to satisfy known rules. In the preliminary stage partial solutions to design problems may be discussed in mathematical terms using frameworks like lattices, graphs, or group theoretical considerations of structural, functional, and visual organization of buildings. The capability to produce mathematically sophisticated geometric structures allows us to generalize the approach further. The theoretical design knowhow in architecture can be partly translated in to some logic and represented in a knowledge base. These rules are used as selection criteria for geometric design candidates in the sense of logical model theory and mathematical optimization. The economy of the system can be developed by using suitable conduct mechanisms familiar e.g. from logic programming. The semantics of logic offers a frame to consider computer assisted and formal generation in design. A number of semantic and pragmatic problems, however, remain to be solved. In any case conceptual analyses based on logic are applicable in order to rationally reconstruct architectural goals contributing to the quality of environmental design, which should be the main goal in the development of design systems in near future.

summary The Creative Synthesis task devised by Finke and Slayton(1988) has been widely used as an experimental measure of mentalsynthesis, but previous studies have often failed to demonstrate anysignificant benefits of external support on participants’ performance.This paper discusses a study that examined novice and expert drawers’performance of synthesis using a modified stimuli set that was designedto increase the load on visuo-spatial working memory. The resultsshowed a significant increase in Transformational Complexity(Anderson & Hesltrup, 1993) of patterns produced by the expert groupwhile using sketching. It is argued that experts are more effective atusing sketching interactively to increase complexity, while novices relymore on using it as a simple memory aid.

title SOLAREXPERT : A Prototype Expert System for Passive Solar Energy Design in Housing
source Canberra: Aust NZ Solar Energy Society, 1987. vol.II: pp. 361-370. Also published in People and Technology - Sun, Climate and Building, edited by V. Szokolay, Univ. of Queensland, Brisbane, 1988
summary Passive solar energy design is not an exact science in which a set of analytical procedures can be followed to produce results. Rather it depends heavily on subjective parameters and experience collected over time which is heuristic by nature. At present this knowledge is available in books but while this knowledge is comprehensive, it is unstructured and not always easy to make use of. A computer-based system allows for flexible interactive dialogue and for the incorporation of analytical procedures which may be required. This paper describes work on SOLAREXPERT, a prototype expert system to aid designers in passive solar energy design for single dwellings. The system operates at a strategic level to provide basic advice on the form of construction and types of passive solar systems and at a spatial zone level to provide more detailed advice on sizes and materials. It allows for modification of the information entered so that users may explore several possibilities

title Designing: Rules, types and worlds
source Design Studies, Volume 9, Number 3, 1988, pp. 24-38
summary Protocols of seven practised designers, all undertaking a common design exercise, have been analysed for patterns of reasoning and use of design rules. Patterns of reasoning were found to be shared among designers and not significantly different from reasoning in everyday life. Rules were largely implicit, overlapping, diverse, variously applied, contextually dependent, subject to exceptions and to critical modification. It is argued that rules are derived from underlying types - functional building types, references, spatial gestalts and experiential archetypes - that serve as `holding environments' for design knowledge.

title The knowledge based representation and manipulation of geometry
source Carnegie Mellon University
summary An approach to the integration of geometric information in knowledge based systems is described as an architecture for geometric reasoning. The general requirements for this integration arise from the need for rich geometry representations in engineering domains and the conflicting demands of current geometric modelling and knowledge based systems. Four concepts are used as a basis: (1) Classes of spatial sets, which act by inheritance as a means for incremental definition by specialization, (2) Features, which denote evaluated portions of a geometric model, (3) Abstractions, which provide partial representations of geometric objects, and (4) Constraints through which spatial relationships are expressed. These four concepts combine in a synergistic manner to define the complete architecture. A prototype implementation of the architecture, built using object oriented programming techniques and a boundary based solid modeller, has been achieved and demonstrated through examples in the domains of robot task planning and automotive parts design.

source CSCW in Practice: An Introduction and Case Studies. pp. 105-126. Edited by Dan Diaper and Colston Sanger, London: Springer-Veriag
summary CSCW is a diverse and eclectic field. The theme which unifies CSCW is the question of group coordination, how it is achieved as a social phenomenon and how it may be actively assisted by computer-based support. The nature of these social processes are variously discussed in many of this book's other chapters. The issue of what is "true" CSCW and what is not is a contentious academic issue. Support for non-routine "professional" work such as collaborative writing would be widely accepted as a paradigm of CSCW (see, in particular, Sharples, Chapter 4; Gilbert, chapter 5; and Diaper, Chapter 6). Electronic mail, however, does not count for some as CSCW, because it is "not really tuned (or tunable) to the needs of the work group" (Greif, 1988). Technologies which support routine work would appear to fall into a particularly controversial category. Traditional office automation systems come under this heading.

summary The proposition of using design optimization to formalize and add rigor to the decision-making process in building and construction was earlier compiled by Radford et al. in 1988, providing an in-depth demonstration of techniques available at the time. Much has changed since, both in the available solution methods and the nature of the problems themselves. This paper provides an updated insight into past and current trends of using this engineering design paradigm to solve architectural design problems, with an emphasis on continuous nonlinear formulations of simulation-based problems. The paper demonstrates different problem formulations and current techniques for solving them. Examples from recent research are used to demonstrate significant achievements and existing challenges associated with formalizing and solving decision-making tasks in architecture.
