summary	After more than a century of domination by neo-Darwinian theory, biological thought is beginning to giveincreasing recognition to developmental theory. Amongst other reasons, this recent widening ofperspective is grounded on the incompleteness of the neo-Darwinian perspective in providing modelsfor the invention of novel forms or species and individual development. Evolutionary design theory hasdrawn much of its inspiration from evolutionary biology and consequently shows analogous flaws. Thispaper demonstrates an adoption of biological developmental theory to the field of design theory in orderto fill the corresponding gap. As natural developmental processes are based on the development ofcellular units, which form composite structures, this paper employs the cellular model as a means for thedevelopment of a corresponding design and construction theory. The discussion of this approachincludes possible linkages between morphologic and behavioral attributes of tissues with implicationsfor self-assembly, growth, healing and self-reproduction of man-made structures.

title	Perception and Painting: A Search for Effective, Engaging Visualizations
source	Institute of Electrical and Electronics Engineers, Journal, March / April
summary	Scientific visualization represents information as images that allow us to explore, discover, analyze, and validate large collections of data. Much of the research in this area is dedicated to the design of effective visualizations that support specific analysis needs. Recently, we have become interested in a new idea: Is a visualization beautiful? Can a visualization be considered a work of art? One might expect answers to these questions to vary widely depending on the individual and their interpretation of what it means to be artistic. We believe that the issues of effectiveness and aesthetics may not be as independent as they might seem at first glance, however. Much can be learned from a study of two related disciplines: human psychophysics, and art theory and history. Perception teaches us how we "see" the world around us. Art history shows us how artistic masters captured our attention by designing works that evoke an emotional response. The common interest in visual attention provides an important bridge between these domains. We are using this bridge to produce visualizations that are both effective and engaging. This article describes our research, and discusses some of the lessons we have learned along the way.

title	Physical and Virtual Tools: Activity Theory Applied to the Design of Groupware
source	Computer Supported Cooperative Work (CSCW), Kluwer
summary	Activity theory is based on the concept of tools mediating between subjects and objects. In this theory, an individual's creative interaction with his or her surroundings can result in the production of tools. When an individual's mental processes are exteriorized in the form of tools - termed objectification - they become more accessible to other people and are therefore useful for social interaction. This paper shows how our understanding of activity theory has shaped our design philosophy for groupware and how we have applied it. Our design philosophy and practice is exemplified by a description of the BUILD-IT system. This is an Augmented Reality system we developed to enhance group work; it is a kind of graspable groupware which supports cooperative planning. The system allows a group of people, co-located around a table, to interact, by means of physical bricks, with models in a virtual three-dimensional (3D) setting. Guided by task analysis, a set of specific tools for different 3D planning and configuration tasks was implemented as part of this system. We investigate both physical and virtual tools. These tools allow users to adjust model height, viewpoint, and scale of the virtual setting. Finally, our design practice is summarized in a set of design guidelines. Based on these guidelines, we reflect on our own design practice and the usefulness of activity theory for design.

title	Relating to the ‘real’ Theories for and Experiences with Educational Database Systems
doi	https://doi.org/10.52842/conf.ecaade.2002.080
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 80-87
summary	One of the most ubiquitous computer applications is the database. Common databases are capable of handling massive amounts of data, which allow users to instantly find the factual data they seek. In most cases the assistance of a database is straightforward and objective. However, when people work with databases with a rich and diverse content, this can lead to unexpected findings, surprises and possibly a revolution in their understanding of a design problem. Furthermore multimedia databases and the systems with a more enhanced set of interactive features provide more appealing results. Databases become most interesting when the creators and the users can rise the data to a level that touches knowledge, wisdom and creativity. This paper goes into questions about the application of databases in architectural education. What can be the role of databases in the education of next generation architects? What should educators offer the students through database content, or what should be left open for creative initiatives? We present a broad overview of possible database content, various modes of interaction with the databases and several ways of representation of the database content. The overview shows areas where educational database technology is still underdeveloped and areas where a lot of concurrent databases exist. The theoretical overview enabled us to set out a further strategy for database applications in our school of Architecture. Besides the theory, we present our recent experiences with a database for architectural realizations. The database of buildings can be used in different educational exercises.

title	Road hierarchy and speed limits in Brasília/Brazil
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

title	Generative Architectural Design and Complexity Theory
source	International Conference on Generative Art
summary	During the past decades, complexity theory has evolved as a new discipline that provides a broad scientific perspective towards dynamic real-life phenomena, challenging the classical linear worldview as well as simple cause-and-effect-style Newtonian physics. For architects, the advent of this new science offers the challenge as well as the chance to reconsider common design approaches and to invent new strategies based on the new paradigms. The actual application of complexity theory to architectural design, however, results in a fundamental dilemma: How can a reflective, ultimately retrospective body of thought (complexity theory) be applied to prospective design challenges (architecture)? Being part of a current MArch thesis project, the proposed paper focuses on this general dilemma between architectural design and complexity theory and discusses actual as well as potential future generative architectural design approaches involving complexity theory. Generative design strategies commonly apply algorithmic methods and formalisms, which can conveniently produce and deal with high levels of complexity. Complexity describes general properties of a system and can be further dissected into several modes: epistemic, ontological and functional complexity. This taxonomy offers insights into generative design applications, which have mostly focused on a limited set of complexity modes. Besides complexity generated by sheer numbers, aspects like functional or hierarchical complexity offer further perspectives on generative systems, processes and output. Considering these aspects of complexity theory, future challenges to generative architectural design can be predicted.

title	Theoretical Perspectives For The Development Of 3D City Models In Architectural Education
doi	https://doi.org/10.52842/conf.ecaade.2003.247
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 247-252
summary	This paper continues the discourse of the round table session of eCAADe 2002 on the problems of existing digital city models. It reviews recent papers on the subject, suggests criteria for the improvement of digital city models, and points out some applications for a broader base of users, and particularly in the field of architectural education. it is suggested here that the design professions of architecture and urban design should be more comprehensively included by broadening the approach to 3dcms. Changes in contemporary architectural, urban planning and design theory, collaborative design practice and constructivist education, lead us to suggest a change of emphasis from 2D urban planning principles to those of 3D urban design and morphology.

title	A Shape Compactness Measurement Indexing with Fuzzy Multicriteria Decision Making Approach
doi	https://doi.org/10.52842/conf.caadria.2002.093
source	CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 093-100
summary	Compactness of a district or zone is determined by considering its appearance and the area of dispersal of the district (Altman, 1998) and it is used as a characteristic to describe shape (Shiode, 1998; Knight, 1997). However, existing compactness measurement used to assess district plans in redistricting applications are vague and imprecision although there are more than thirty over Euclidean or non-Euclidean measurement methods. Therefore, this paper presents an integrated shape compactness measurement indexing with a fuzzy multicriteria decision making approach (FMCDM) to enhance the measurement of shape compactness. An experiment is conducted in order to verify the practically of the proposed model to improve existing compactness measurement method.

title	BEYOND MODELLING: AVANT-GARDE COMPUTER TECHNIQUES IN RESIDENTIAL BUILDINGS.
source	I Jornadas de Investigacion en Construccion, Madrid, 2-4 June, 2005.
summary	If the result of computer innovations can be interpreted as an emerging “difference” in the quality of constructed space, then in order to truly understand what future applications may be regarding architecture at present, we should look at what advanced functions are available in the process of designing forms and space (DeLuca and Nardini, 2002). Recently the so called parametric approach, a technique for describing a large class of designs with a small description in programming code, has become a focus of attention in architectural computing. In this paper, we reflect on the current use of parametric tools using real case studies as well as our own proof of concept parametric programmes and report on how the avant-garde computer techniques may help to increase the quality of residential building.

title	Making Sense of Presenting Design Ideas through Animated Form
doi	https://doi.org/10.52842/conf.ecaade.2002.560
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 560-563
summary	This paper describes both conventional and computational ways of expressing and exploring design concepts with the use of models. We explain the role and function of the model in the design process, and investigate the ways in which models become reflections and representations of architects’ design thinking. We compare and contrast the physical properties of conventional models with those of three-dimensional computer models, and the corresponding processes of model creation, model development, and model modification. The paper includes a brief overview of commonly used forms of computer representations often encountered in Computer Aided Design applications. Whatever the visual richness of computer models in virtual environments can be, we believe that, just as in the use of conventional two-dimensional architectural drawings, computational presentations of architectural design concepts have their own conventions of use. This paper addresses the need to more accurately understand these conventions of using computer models for the representation of architectural design concepts. Therefore, we will illustrate the more dynamic qualities of computer models, which have the potential to allow designers to escape from the restrictions and constraints of physical form. In particular, we demonstrate these qualities in the context of architectural presentations in the medium of computer animation. These new forms of expression of design thoughts and ideas go beyond mere model making, and move more towards scenemaking and storytelling. The latter represents new methods of expression within computational environments for architects and designers.

title	Free-form design using axial curve-pairs
source	Computer-Aided Design, Vol. 34 (8) (2002) pp. 583-595
summary	Deformation of 3D shapes usually requires the use of a deformation tool. The freeform deformation technique requires the use of a lattice of control point for deforming anobject. This may require a synchronized movement of the lattice control points in order to obtain the desired effects. The axial deformation technique allows an object to bedeformed by manipulating an axial curve. However, unexpected twist of the object may be obtained. This is a result of the lack of control on the local coordinate frame of thecurve. This paper presents a technique for deforming objects with a set of axial curve-pairs. The use of a curve-pair allows the local coordinate frame to be controlledintuitively. A curve-pair is composed of a primary and an orientation curve. The orientation curve is an approximate offset of the primary curve. A technique is proposed formaintaining the relation between the primary and the orientation curve when the curve-pair is adjusted. By associating a complex 3D object to a curve-pair, the object can bestretched, bended, and twisted intuitively through manipulating the curve-pair. This deformation technique is particularly suitable for manipulating complex shapes (e.g.decorative components) in industrial and aesthetic design, and is also suitable for modelling characters and animals with flexible bodies. Adjusting the curve-pair according tosome motion constraints produces different postures of a character or animal model. This in turn can be used as decorative components for aesthetic design.

summary	In the last decade, the ubiquitous computing paradigm has pushed computation out of desktop and made computational services pervasive throughout a physical environment. In this paper, we describe the work in progress in developing ubiquitous/pervasive applications supporting digital design media presentation. The result of the experimental study in various spatial settings is reported. Finally, we present a model of interaction towards a human-centered reactive environment, and discuss some interaction and social issues that must be addressed in implementation.

summary	Graduate Institute of Architecture, National Chiao Tung University, Hsinchu, 30050, TAIWAN The adaptation of the word cyberspace (Gibson, 1984) following the emergence of the World Wide Web Internet not only succinctly revolutionized the correlation of time and space but also poised to challenge how we view the existing spatial concept. This research tries to use protocol analysis to examine text-based cyberspace, such as bulletin board, chart rooms and so forth, and the objective of this research is to realize the spatiality of cyberspace through the cognitive point of view, and to compare the differences of the definitions and perception ways of spatiality between people with general domain and in design fields. Finally, we validate the existence of cyberspace, where the process not only allows further categorization of spatial elements concluded from the earlier study, but discover that varied backgrounds can affect how a user defines and perceives cyberspace (Strate, 1999).

title	A Multimedia Application to Support Professionals in an EnvironmentallyResponsible Building Design Process
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary	One of the problems faced by the design professionals in trying to incorporate thermal and acoustic concerns when designing a building is the quantity and diversity of building materials that can be applied to improve a poor indoor environment and, in many cases, to later reduce energy consumption. The large amount of information on building materials usually provided as documents makes it almost impossible to the designer to compare products. In the light of the stated facts, the objective of this work was the development of a multimedia application, which was thought as a module of a more comprehensive system able to support professionals in an environmentally responsible building design process. The application takes advantage of the ability of computers to handle texts, images, sounds and movies to introduce several building materials and their characteristics to the designers, in an interactive way. The conclusion of this stage shows that rather than being a module of a larger system, the developed application can work as a powerful standalone multimedia catalogue of building materials that have special interest on thermal, acoustic, and thermal-acoustic applications. It is an application that are notonly fundamental in a support system for effective building design, but also a powerful tool for training architecture students as part of an environmentally responsible building design process.

title	On an alternative framework for building virtual cities: supporting urban contextual modeling on demand
source	Environment and Planning B: Planning and Design, Vol. 29, pp 87-103, Jan 2002
summary	For various purposes, virtual city applications have been developed around the globe to provide users with online resources and services over the Internet. Following our research on the Sheffield Urban Contextual Databank (SUCoD) project, this paper presents an alternative framework for building virtual cities, which goes beyond conventional static urban modelling. A three-tier system framework is described in conjunction with the design and implementation of the SUCoD prototype. We demonstrate SUCoD's novel functionalities by showing that complex urban contextual information sets, including three-dimensional interactive models, multilayer interactive maps, and hypermedia documents, can be retrieved dynamically by user-specified urban contextual attributes, spatial loca- tions, and boundaries. The three-tier framework also facilitates system development in an extensible way, allowing continuous parallel extensions of system functionalities, user-interface components, and contextual data resources. SUCoD's dynamic capabilities are considered crucial in its future uses for urban contextual modelling on demand in relation to the past, present, and future of the City of Sheffield.

Moreover, the report also discusses the feasibility of the usage of verbal analysis in the computer and network environment. All the verbal and visual elements of space that have been found through our experiments and interviews are presented here. In addition, the issues concerning the methodology of the verbal analysis have been pointed out with quantitative and qualitative analysis, and an amendment formula has been suggested. Finally, the researchers also explore the comparison of the spaces that are created verbally and visually, as well as the comparison of the actual and virtual spaces.

summary	Computer simulation is used well in historical architecture restoration and research in a small scale for a long time, and should be used in a larger scale to represent a city, especially a disappeared city. Therefore how to utilize computers to coordinate both architectural and cultural data of a city becomes an important issue. This study takes Chang-an City that existed 1400 years ago but disappeared now as example and tries to develop a computerized and visualized method to simulate and realize a disappeared city and it’s life. Finally, we represent simulations in a virtual reality cave (VR Cave) to make navigators evolving in and interacting with the virtual Chang-An City.

summary	Evolution of trends in the realm of computer aided architectural design (CAAD) has seen the convergence of technologies – complementing traditional tools with emerging sciences like Information Technology (IT) and multimedia applications. This appliqué of technologies has not just expanded the scope and enhanced the realm of CAAD research and practice, but is also breaking new frontiers. This creative nexus will be realised at the 7th International Conference on Computer Aided Architectural Design Research In Asia (CAADRIA 2002) to be held at the Faculty of Creative Multimedia, Multimedia University, Malaysia, between 18th-20th April, 2002. CAADRIA 2002’s theme, "Redefining Content", seeks to recognise and infuse these emerging components in the field of architecture and design with a holistic approach towards online, digital and interactive systems. The 41 papers compiled were selected through a blind review process conducted by an international review panel. To reflect the multi-disciplinary nature of this year's conference, the chapters are arranged topically to facilitate the in-depth study of key components. The component sessions include: // Web Design, Database and Networks // CAD, Modelling and Tools // Collaborative Design, Creative Design and Case Reasoning // Simulation and Prototyping // Virtual Environment and Knowledge Management // Design Education, Teaching and Learning /// We believe that this specialised approach will provide a deeper and more illuminating feel of the various components and their critical convergence in the field of architecture and design.

title	Separating the Knowledge Layers: Cognitive Analysis of Search Knowledge Through Hierarchical Goal Decompositions
source	Proceedings of the ASIST'2002 (2002), 204-213
summary	Hierarchical goal decompositions have proved to be a useful method to make explicit the knowledge required by users to perform tasks in a wide range of applications such as computeraided drafting (CAD) systems. This analysis method progressively decomposes a given task starting from the task layer on the top of the decomposition, to the keystroke layer at the bottom. The analysis enables a close inspection of the knowledge required to perform the task at each layer of the decomposition. In this paper we show how the method of hierarchical goal decomposition can be used to understand more precisely the knowledge that is required to perform information search tasks. The analysis pinpoints: (1) the critical strategies in the intermediate layers of knowledge that are known by experts searchers; (2) why such knowledge is difficult to acquire by novice searchers; (3) how the analysis provides testable predictions of behavior based on the acquisition of different types of knowledge. We conclude by discussing the advantages provided by hierarchical goal decompositions, and how such an approach can lead to the design of systems and training.
