title	Conception of Urban Space – Simulators Supporting Planning Work
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 87-90
summary	Experimenting with “space”, joint exploring solution possibilities with all those concerned and the anticipation of the future involving as little risks as possible are important functions of space-related simulation contributing to increasing of knowledge, decision-finding and communication throughout the planning process. Questions as to conception of urban space, the modeling of urban volume and urban design, the improvement of spatial match (“fit”) and workability regarding utilization (”fitness for use”) call for suited simulators supporting planning work. All planning phases of urban-spatial planning processes are to benefit thereby: understanding is promoted, spatial characteristics developed, preservation- and renewal priorities are deduced, variants are conceived, spatial impact analysis of spatial ideas and graphic communication are to act as basis fordecision-finding. The present contribution also discusses the application possibilities of the “CAVE” (space with threedimensional image projections) as planning tool. The following questions are to be covered: qualitative and quantitative aspects of modeling of urban space, planning benefits arising from differing “levels of details” (LOD’s), “navigation in” and “interaction with urban spaces”, testing in line with requirements and examples of planning practice as well as current research- and development needs.

title	Can Doors and Windows Become Design Team Players?
source	Gero JS and Brazier FMT (eds) (2002) Agents in Design 2002. Key Centre of Design Computing and Cognition, University of Sydney, pp. 3-22
summary	In an architectural design session, suppose design objects such as doors, windows and rooms can look after themselves, what kind of recommendations would a designer get? What is the nature of a design environment that facilitates such interactions? Where would a design object acquire the knowledge that allows it to interact intelligently? How would such localized recommendations be aggregated to support global design decisions made by the designer? This paper investigates these questions through the notion of objects as agents in design.

title	Role of Trust in Automated Distributed Design
source	Gero JS and Brazier FMT (eds) (2002) Agents in Design 2002. Key Centre of Design Computing and Cognition, University of Sydney, pp. 71-83
summary	Distributed design involves many participants, each with their own expertise and goals. Information acquired from different participants may be valued differently in terms of accuracy and trustworthiness. Human participants in a distributed design setting often know whom they trust, and whose abilities they value. This knowledge is not often made explicit. It does, however, influence distributed design processes (i.e. the way in which members of a design team assess and incorporate each others' designs, objectives, evaluations). These trust relations need to be made explicit to be able to effectively support distributed design.

title	Construction of Digital City in Physical City: Cyberspatial Cognition Approach to the Project of Hsin-Chu Digital City in Taiwan
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. 109-116
doi	https://doi.org/10.52842/conf.caadria.2002.109
summary	The cyberspace upon physical space forms a new spatial structure to increase the influence on the urban fabric and the concept of space in architecture. Today, digital cities are being developed all over the world. By using a city metaphor, digital cities integrate urban information and create public spaces. How do digital cities directly connect to physical cities and become an imaginable city? Therefore, we argue that a new spatial analysis theory must be established for digital city, comparing with theories of disciplines, to find the explicitly spatial structures and relations in digital city upon physical city.

title	Design space navigation in generative design systems
source	Automation in Construction 11 (1) (2002) pp. 1-22
summary	Generative design systems make it easier for designers to generate and explore design alternatives, but the amount of information generated during a design session can become very large. Intelligent navigation aids are needed if designers wish to access the information they generate with ease. We present a comprehensive approach to support information navigation in requirement-driven generative design systems, which gain their power form explicit representations of design requirements, which in turn add to the information generated by the system. Our approach takes into account studies dealing with human spatial cognition, wayfinding in physical environments, and information navigation in electronic media. We structure the information to be accessed in terms of a five-dimensional design space model that applies across generative design systems of the type considered here. The model structure supports basic generic navigation operations along its five dimensions. We validated the model in the context of the SEED-Layout system and used it to extend the built-in navigation tools of the system through novel ones, which we subjected to a limited usability study. The study suggests that these tools have promise and warrant further investigation.

title	Situated Computing: A New Paradigm for Design Computing
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, p. 1
summary	Computer usage in design has largely been in the areas of document production, 3D modelling and to a lesser extent in specialised design analysis and design synthesis tasks. This use of computers by designers has been based on well-defined practices that have their genesis in the scientific approach to knowledge. Just as knowledge is independent of its use and independent of its user, so computer programs are designed to be independent of their use and independent of their users. This talk presents a complementary paradigm based on the notions of situated cognition as the basis of the development of new kinds of computational design tools.Situated cognition holds that where are you and when you are there matters and that the state you are in affects what you do. The fundamental difference is between encoding all knowledge prior to its use to allowing the knowledge to be grounded in the interaction between the computational system and its environment. In addition to the concepts of situated cognition there is another important concept called constructive memory. Constructive memory changes our view of “memory” in acomputational system from being a thing in a place that can be accessed with the correct index to being a process that produces a “memory” when needed. Thus, memory is constructed as needed and becomes a function of both the question it is used to respond to and the situation within which it was asked. These concepts provide the foundation for the developmentof novel tools to support computer-aided designing. Examples of situated cognition and constructive memory will be presented. This will be followed by examples of situated design analysis and situated computational design creativity.

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title	An Agent-Based System for Capturing and Indexing Software Design Meetings
source	Gero JS and Brazier FMT (eds) (2002) Agents in Design 2002. Key Centre of Design Computing and Cognition, University of Sydney, pp. 203-218
summary	We present an agent-based system for capturing and indexing software design meetings. During these meetings, designers design object-oriented software tools, including new agent-based technologies for the Intelligent Room, by sketching UML-type designs on a white-board. To capture the design meeting history, the Design Meeting Agent requests available audio, video, and screen capture services from the environment and uses them to capture the entire design meeting. However, finding a particular moment of the design history video and audio records can be cumbersome without a proper indexing scheme. To detect, index, and timestamp significant events in the design process, the Tahuti Agent, also started by the Design Meeting Agent, records, recognizes, and understands the UML-type sketches drawn during the meeting. These timestamps can be mapped to particular moments in the captured video and audio, aiding in the retrieval of the captured information. Metaglue, a multiagent system, provides the computational glue necessary to bind the distributed components of the system together. It also provides necessary tools for seamless multi-modal interaction between the varied agents and the users.

title	What Designers See from a Case? A Cognitive Approach
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. 167-174
doi	https://doi.org/10.52842/conf.caadria.2002.167
summary	In the behavior of human cognition, Schank, a cognitive researcher, claims that human frequently rely on past experience to solve new problems. The information and knowledge of well-trained designers was obtained from fundamental training courses in schools, from everyday experience, and importantly from several design cases. Acquiring knowledge by seeing cases is the most important activity in the design process. But, there are no related works from cognitive view to discuss what and how designers see from instances. Thus, this paper attempts to investigate what designers can see as some meaningful elements from instances, what relationships are among elements and knowledge which retrieved from designers’ long-term memory, and how new obtained knowledge influences the design outcomes.

title	Prêt-à-Construire – An Educational Inquiry into Computer Aided Fabrication
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 162-165
summary	This paper aims to show and discuss the relevance of developing necessary strategies for reintegrating the concept of fabrication into the architectural design process. The discussion will be partly based on the outcome of a graduate architectural design studio conducted in Spring semester 2002-2003. The graduate studio was part of a series of exploratory studies conducted on the nature of architectural design process transformed by information technologies. Preceded by studios investigating cognition and representation, this last studio focused on the concept of fabrication. The overarching aim of the studio series was to put CAD and CAM in context both within the actual architectural design process and within architectural education. The last of this series, which will be discussed within the frame of this paper, has specifically focused on CAM and the concept of fabrication in architecture. In accordance with the nature of a design studio, the research was more methodological than technical. The studio derived its main inspiration from the constructional templates used in dressmaking, which can be considered as an initial model for mass customization. In this context, the recladding of Le Corbusier’s Maison Domino was given as the main design problem, along with several methodological constraints. The main constraint was to develop the design idea through constructional drawings instead of representational ones. The students were asked to develop their volumetric ideas through digital 3D CAD models while working out structural solutions on a physical 1/50 model of Maison Domino. There was also a material constraint for the model, where only specified types of non-structural paper could be used. At this stage, origami provided the working model for adding structural strength to sheet materials. The final outcome included the explanation of different surface generation strategies and preliminary design proposals for their subcomponents. The paper will discuss both the utilized methodology and the final outcome along the lines of the issues raised during the studio sessions, some of which could be decisive in the putting into context of CAD – CAM in architectural design process. One such issue is mass customization, that is, the mass production of different specific elements with the help of CAM technologies. Another issue is “open source” design, indicating the possibility of a do-it-yourself architecture, where architecture is coded as information, and its code can be subject to change by different designers. The final key issue is the direct utilization of constructional drawings in the preliminary design phase as opposed to representational ones, which aimed at reminding the designer the final phase of fabrication right from the beginning. Finally, the paper will also point at the problems faced during the conduct of the studio and discuss those in the context of promoting CAM for architectural design and production in countries where there is no actual utilization of these technologies for these purposes yet.

title	A Complex Systems Perspective on How Agents Can Support Collaborative Design
source	Gero JS and Brazier FMT (eds) (2002) Agents in Design 2002. Key Centre of Design Computing and Cognition, University of Sydney, pp. 95-111
summary	Almost all complex artifacts nowadays, including physical artifacts such as airplanes, as well as informational artifacts such as software, organizational designs, plans and schedules, are created via the interaction of many, sometimes thousands of participants, working on different elements of the design. This collaborative design process is typically expensive and time-consuming because strong interdependencies between design decisions make it difficult to converge on a single design that satisfies these dependencies and is acceptable to all participants. Complex systems research concerning the generic dynamics of distributed networks has much to offer to the understanding of this process. This paper describes some insights derived from this novel perspective.

doi	https://doi.org/10.52842/conf.caadria.2002.117
summary	Recent studies, both collaborative design system and scenario scripting, attempt to explore further CG media. Corbusier pointed out that good architecture is a place where people can walk unrestrainedly and feel free in spirit. However, it is apparent that the human figures are still in animation, whereas they are free to move in the real world. The human figure always plays an important role in the development of design media. The objective of this paper is to develop a new design method using CG media and to study the process of dynamic human texture mapping within the CG. This research conducted a design experiment using computer as the sole design medium. The results show that the new design method not only altered the behavior of the designer, but also impacted design thinking cognition.

title	A Knowledge Based Collaborative Design Environment
source	Gero JS and Brazier FMT (eds) (2002) Agents in Design 2002. Key Centre of Design Computing and Cognition, University of Sydney, pp. 233-246
summary	In this paper, we propose an agent based collaborative design environment in which human designers and software agents interact with each other, exchange design information and keep track of state information to assist with collaborative design. First of all, it presents a hierarchical multi-agent system architecture for integrating design and engineering tools, software agents and human specialists in an open environment. The hierarchical multi-agent system architecture offers a promising framework with their novel approaches for dynamically creating and managing design tasks in widely distributed and ever-changing design environments. Secondly, it introduces a collaborative design process model and the dynamic management approach for collaborative design process. Then, the structure of a design agent, its static knowledge and dynamic knowledge are introduced respectively. The knowledge based design approach provides a foundation for supporting reusable design activities. Finally, the cooperative design process is illustrated by a bicycle design example.

The two major structural aspects of this agent are Avatar Agent and Design Agent. The UcVA agent in this paper is presented from various perspectives: structure, process, and use scenarios. A proposed application of these agent models and an analysis of User-centred Virtual Architecture designed by this agent illustrates and evaluates this approach to designing virtual architecture.

doi	https://doi.org/10.52842/conf.acadia.2002.333
summary	The ability to arrange information graphically in digitally represented Cartesian space offers obviousadvantages over two-dimensional graphical reductions. Adding time to the spatial palette provides adynamic dimension. Cartesian space used for these purposes, however, reinforces an ocular-centricapproach to information delivery. We can include sound in order to seek a sensory balance, therebyimproving cognition and enhancing dimensionality within an ‘information space’, especially for complexmaterial requiring greater interactivity or ‘audience’ participation. Combined visual and audio synthesisoffers multidimensional and multi-sensorial environments that challenge existing linear and twodimensionalpresentation orthodoxies – ‘audience’, for instance, presupposes a lecture to be listened to.This paper presents work in progress investigating the use of sonification as both a thematic andnavigational vehicle in dynamic presentation environments.

source	Gero JS and Brazier FMT (eds) (2002) Agents in Design 2002. Key Centre of Design Computing and Cognition, University of Sydney, pp. 181-200
summary	A simple learning mechanism was added to an agent-based computational design system to see if it could then transfer knowledge across problems. An existing system, A-Design, was enhanced by giving it the ability to store useful design knowledge in a memory store so that this knowledge could be used in new design problems. Three electromechanical design problems were used to evaluate this new learning mechanism, and results indicate that this simple learning mechanism is successful at transferring design knowledge to new problems with some limitations.
