Liu, H., M Tang, and John Frazer. "A Knowledge Based Collaborative Design Environment." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 233-246. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. 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.
Liew, P.S., and John S. Gero. "A Memory System for a Situated Design Agent Based on Constructive Memory." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 199-206. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. Situated design agents require new types of memory. The design of a memory system for use in such a design agent, based on the notion of constructive memory is proposed. The specification of the memory system is derived from the architecture of a situated design agent. Cognitive studies of the human memory system provide the functional and behavioural characterization of the memory system.
Lin, C.Y.. "A Place Where People are Free to Move: Exploring Dynamic Texture Mapping in Computer Graphic Systems." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 117-122. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. 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 behaviour of the designer, but also impacted design thinking cognition.
Bong, C.W., and Y.C. Wang. "A Shape Compactness Measurement Indexing with Fuzzy Multicriteria Decision Making Approach." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 93-100. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. 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.
Chen, S.C.. "Aided Design Strategy Under the Professional Knowledge-Orientation." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 293-300. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. Professional knowledge is a key component of the decision making process, as well as a major part of the thinking process. This research uses a strategy oriented by professional knowledge to assist the analysis of strategies in the design process, and to incite different design thinking under the operation models of media, through the basis of the design process, analyse the utilization of professional knowledge by designers in the design process and the different knowledge understanding methods under different media utilizations.
Bae, H.A., M.R. Kim, S.Y. Shin, H.A. Kim, and C.S. Yoon. "An Application of Photogrammetry Measuring Technology to Parametric Modeling of Korean Traditional Wooden Structure." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 139-146. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. To construct a 3D parametric model of Korean traditional wooden structure, the fundamental process is to obtain the dimensions of each building. An application of measuring high technology helps this process accomplished more efficiently. However PhotoModeler is a photogrammetric program to measure the dimension using photographs. The information derived from PhotoModeler is used to clarify the design rule inherent in a Korean traditional mansion type building - UnHyun Palace.
Paranandi, Murali. "An Inquiry into Computers in Design: When Cardboard Met Computer ." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 329-337. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. This paper reflects on the experiences of teaching undergraduate design studios for past 4 years and presents a systematic investigation conducted in a classroom setting to further understand the role of computer in conceptual stages of design. A case study project inquiring the implications of using two different forms of media, namely cardboard and computer, for design development during conceptual stages is presented. Twelve novice designers were challenged to learn and use computers in a five-week design project. A conceptual framework for understanding the discovery and usefulness of computer in their design process was developed and tested. An analysis of the outcome indicated that computers played a positive role in student innovation, improving possibilities for discovery. It further revealed that the employing cardboard was useful in turning the abstract discoveries made by the computers into productive and useful design solutions. It also supported the notion that the novice designeris use of photorealistic possibilities offered by computer visualization (rendering, animation) during conceptual stages of design had an effect of distraction rather than a design aid.
Papamichael, Konstantinos, and Vineeta Pal. "Bridging the Gap Between Building Science and Designing Studios." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 123-130. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. Design studios and building science courses have been conducted independent of each other, mainly due to a lack of tools that allow quick and easy consideration of building science criteria, such as comfort and energy requirements, during the design process. Existing tools are not user-friendly and their use requires significant effort in gaining familiarity with the input requirements, understanding the modelling assumptions and interpreting the output. This paper is about the Building Design Advisor (BDA), an evolving computer-based tool intended to bridge the gap between design studios and building science considerations by addressing the above-mentioned limitations of existing tools. BDA allows automatic preparation of input files to multiple simulation tools while the user is working in a CAD environment. BDA automatically activates the relevant simulation tools when the user selects performance parameters to be computed and provides the results in a graphical form, allowing comparison of multiple design options with respect to multiple performance criteria. The paper includes considerations for the use of the BDA in the design studio and ends with a description of the current development efforts and future plans.
Bay, J.H.. "Cognitive Biases and Precedent Knowledge in Human and Computer-Aided Design Thinking." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 213-220. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. Cognitive biases (illusions) and potential errors can occur when using precedent knowledge for analogical, pre-parametric and qualitative design thinking. This paper refers largely to part of a completed research (Bay 2001) on how heuristic biases, discussed by Tversky and Kahneman (1982) in cognitive psychology, can affect judgement and learning of facts from precedents in architectural design, made explicit using a kernel of conceptual system (Tzonis et. al., 1978) and a framework of architectural representation (Tzonis 1992). These are used here to consider how such illusions and errors may be transferred to computer aided design thinking.
Fukuda, Tomohiro, Ryuichiro Nagahama, Atsuko Kaga, and Tsuyoshi Sasada. "Collaboration Support System for City Plans or Community Designs Based on VR/CG Technology." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 257-264. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. This paper reports the collaboration support system for city plans or community designs based on virtual reality (VR) or computer graphics (CG) technology. This time we report to elaborate the extended potable VR equipment and expression method with CG to allow for the realistic viewing of night scenes, and apply to real projects.
Chang, Y.L., Y.Z. Lee, and Y.T. Liu. "Construction of Digital City in Physical City: Cyberspatial Cognition Approach to the Project of Hsin-Chu Digital City in Taiwan." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 109-116. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. 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.
Gero, John S., and Ricardo Sosa. "Creative Design Situations: Artificial Creativity in Communities of Design Agents." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 191-198. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. This paper presents the outline of experiments with a behaviour-based computational model of creativity in design called Creative Design Situations. This model aims to allow the study of social creativity through the computational implementation of a community of creative design agents.
Lawrence, Peter. "Designing Business." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 17-Se. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. On a number of occasions after telling people about Corporate Design Foundation and what we do, their reaction is “well, business now understands the importance of design, right?” The answer is yes and no. There is, as they say, good news and bad news. A growing number of senior business executives do understand the possibilities of design. But many still do not. Unfortunately, the majority of mid-level managers do not. While there has been an increasing amount written about design in the business press, there has also been an equal amount in the general press which is misleading or just wrong. There is a great deal more to do.
Reffat, Rabee. "Designing with Computers in a Paperless Design Computing Studio." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 347-354. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. The advancements in digital design and communications are reshaping the economics of architecture and design practices. Designing with computers is based on establishing a fruitful dialogue between the designer and the tool. The “digital imperative” to switch from analogue to digital mode have already begun to manifest itself at the schools of design and architecture in the form of the paperless Design Computing Studio (DCS). This paper describes and reflects on the designing and teaching approach implemented in a paperless DCS within the domain of architectural design. The paper presents the implementation of this approach, on the first year students of the new degree of Design Computing at the University of Sydney and analyses the studentsi design learning experience in the DCS.

Ham, Jeremy J.. "Discovering Construction Through Architecture." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 339-346. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. This paper discusses a digitally integrated educational programme wherein students discover construction through architecturei from innovative and technologically diverse student projects using digital and physical media within a role-play environment. Student output is examined to determine engagement in a programme informed by “reflective making”. This redefinition of content is centred on priming graduates with the abilities and skills to lead the construction industry of the future.
Lou, C.W., Atsuko Kaga, and Tsuyoshi Sasada. "Environmental Design with Huge Landscape in Real-Time Simulation System: Real-time Simulation System to Real Project." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 265-272. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. This paper is the culmination of a period of studying and participating in certain real project on environmental design with realtime simulation system application. The focus of this paper is on understanding that a generally real-time simulation system, can render a complex scene that consisted by a huge landscape model with millions polygons and building models with thousands details. It is also more than just a collection of unorganized techniques. This paper must dual with issues of scene elements management as a front end that efficiently provide the ability to process complex and moving objects in a physically realistic way. We establish a platform providing good support for the environmental designers.
Zhou, Qi, Robert Krawczyk, and George Schipporeit. "From CAD to IAD: a Working Model of the Internet-based Engineering Consulting in Architecture." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 073-80. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. Information technology has become so powerful that what is conventionally called CAD might evolve into iAD (Internet Aided Design) in the near future (Zhou 2000). For Internet applications in the AEC industry, most of the efforts and success have been concentrated on project management and collaboration, while in the design and engineering consulting area, limited progress has been made. During the period of Internet development, the nature of the fragmentation of the AEC industry has not been changed. Based on previous research of surveys of development of Internet applications in the AEC industry (Zhou 2001), and the study of information technology both available today and in the near future, we propose a general abstracted model of an Internet-based consulting system by integrating a variety of disciplines and functions of design and construction processes. This model will cover a range of design phases, such as, information gathering, automatic remote consultation, specific problem solving, and collaboration. Finally, in future follow up research, we will apply the proposed model to steel construction in architectural design, and develop a prototype simulation by selecting one type of structural system.
Lee, Alpha, and Alpha W. K. Lee. "From Simulation to Stimulation - Stimulative Design Computing Learning and Teaching Environment Based on Multiple Representations." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 207-212. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. Design computing is an interdisciplinary field that centers on the intersection of design, computer science, and cognitive science. These multi-dimensional faces of this new paradigm necessitate a mutual understanding of computing and design as a whole, which are usually conceived as separate stages of computer-mediated design. This paper explores the use of multiple representations in stimulative design computing learning and teaching environment. This paper starts with an overview of computer-mediated collaborative learning, multiple representations and learner-centered design. Then issues related to the methodology in implementing the system are discussed. Agent models and prototype of the above computer-mediated collaborative learning system are constructed. The research is under progress.

In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 101-108. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. Urban landscape is an important visual form to reflect the characteristics of a city. This paper attempts to transform the urban landscape into information landscape to reveal the city characters, build a web-based system to navigate the 3D city model, and better understand the urban life by scene-based scenarios and role-play. The Digital Tainan project is presented for demonstration and discussion.

In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 241-248. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. In this paper, we present a GIS based approach to evaluate the visual perception quality of mountain skyline. Through computer generated analytical maps and perspectives, this tool can assist planners to define the visual reservation scopes for mountain skyline within urban area. It also offers concrete data supporting for appropriate strategy in building layout or site planning to preserve valuable natural skyline scenery.

In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 301-308. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. 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 itis 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.
Reffat, Rabee. "Intelligent Agents for Concept Invention of Design Forms." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 55-68. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. Concept invention refers to the act of discovering new concepts for the first time. Concept invention may require a new interpretation that motivates new mappings of the situation prior to the discovery of a new concept. This paper is concerned with developing intelligent design agents that would be capable of inventing creative concepts of design forms, shapes and compositions while involved in the design process. A new approach of exploiting the old notion of “displacement of concepts” with regard to concept invention in designing in the form of mobile design agents is adopted and utilised in developing the structure of intelligent mobile agentbased system.

In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 285-292. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. 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.
Eshaq, Ahmad Rafi Moham, Che Zulkhairi, and P. Karboulonis. "Interactive Storytelling and Its Role in the Design Process." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 151-158. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. Projects of ever increasing complexity and size have incited the need for new and robust design methodologies and tools in an effort to manage complexity, lower costs, ascertain quality and reduce risk. Technology convergence through the growing availability of networked computers, rapid progress in Computer Aided Design (CAD) and information management have encouraged the undertaking of even more complex designs that demand high degrees of interaction, collaboration and the efficient sharing and dissemination of information. It is suggested that interactive storytelling and interactive design (Rafi and Karboulonis, 2001) techniques that use non-linear information mapping systems can be deployed to assist users as they navigate information that is structured to address localized needs as they arise. The design process is a collaborative effort that encompasses diverse knowledge disciplines and demands the management and utilization of available resources to satisfy the needs of a single or set of goals. It is thought that building industry specialists should work close together in an organised manner to solve design problems as they emerge and find alternatives when designs fall short. The design process involves the processing of dynamic and complex information, that can be anything from the amount of soil required to level lands - to the needs of specific lightings systems in operation theatres. Other important factors that affect the design process are related to costs and deadlines. This paper will demonstrate some of our early findings in several experiments to establish nonlinear storytelling. It will conclude with a recommendation for a plausible design of such a system based on experimental work that is currently being conducted and is reaching its final stages. The paper will lay the foundations of a possible path to implementation based on the concept of multi-path animation that is appropriate for structuring the design process as used in the building industry.
Garner, Steve, and P. Mann. "Interdisciplinarity: Perceptions of the Value of Computer Supported Collaborative Work in Design for the Built Environment." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 221-228. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. This paper presents the findings from a study into the current exploitation of CSCW in design for the built environment in the UK. The research is based on responses to a web-based questionnaire. Members of various professions including civil engineers, architects, building services engineers and quantity surveyors were invited to complete the questionnaire. The responses reveal important trends in the breadth and size of project teams at the same time as new pressures are emerging regarding team integration and efficiency. The findings suggest that while CSCW systems may improve project management (e.g. via project documentation) and the exchange of information between team members it has yet to significantly support those activities that characterize integrated collaborative working between disparate specialists. The authors conclude by combining the findings with a wider discussion of the application of CSCW to design activity - appealing for CSCW to go beyond multidisciplinary working to achieve interdisciplinary working.
Kvan, Thomas. "Learning Through Structural Activity in Collaborative Computer-Aided Design." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 355-360. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. The role of structural activities and other solution searching activities in design learning and problem solving have been identified in laboratory studies of problem solving and also in case studies of design teaching.. In laboratory studies, students have solved creative problems collaboratively under various communication conditions. The case studies follow students working on the same problem under two conditions - one group is taught using traditional face-to-face teaching while the other group is additionally supported by a textbased web board. This paper review findings from three experiments from which we can see that students producing above average solutions involved more structural activities than the mediocre cases. These successful cases engaged in textual expression of their design solutions. Computer tools for design should therefore support multiple representations of design work.

In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 57-64. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. The work described here is aimed at developing city models, with underlying data, in such a way that the model and data can be accessed quickly and efficiently. A particular outcome of our approach to the work is that the model and associated data can be accessed through a palmtop device. This degree of portability opens up a range of opportunities to access this important information, the kind of information related to city models and associated data that is expanding daily.
Tsou, Jin-Yeu, B. Chow, and S. Lam. "Performance-Based Simulation for the Planning and Design of Hyper Dense Urban Habitation." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 249-256. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. The rapid development of the economy and urbanization create great pressure on population of Hong Kong, China and other developing countries. This not only brings great changes on the form and style of the urban sphere, but also, challenges to the natural environment and resources to support urban habitation. Regarding the process of urbanization, the development of the housing industry becomes the focus to resolve the need of materialization for urban living. For this reason, from time to time, technical and economical considerations are always prior to the significance of human settlement environment, humanity, and sustainable development. Considering the deficiency in urban human settlements environment, especially in responsiveness to the natural environment. Information technology (IT) undoubtedly can help to promote and assess the design and planning quality in both environmental and regional microenvironment aspects. A research project-Environmental Responsible Architecture and Urban Design (ERAU)-is established to support urban scale planning, information processing, and computer-aided performance evaluation on both micro and macro building design and planning efficiency.

Sosnov, A., P. Macé, and G. Hégron. "Semi-metric formal 3D reconstruction from perspective sketches ." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 285-294. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. We present a new approach for accurate and fast reconstruction of 3D models from hand-drawn perspective sketches and imposed geometric constraints. A distinctive feature of the approach is the decomposition of the reconstruction process into the stages of correction of the 2D sketch and elevation of the 3D model. All 3D constraints that describe the spatial structure of the model are strictly satisfied, while preferences that describe the model projection are treated in relaxed manner. The constraints are subdivided into the projective, affine and metric ones and expressed in algebraic form by using the Grassmann-Cayley algebra. The constraints are resolved one by another following the order of their types by using the local propagation methods. The preferences allow to apply linear approximations and to systematically use formal methods. 
Huang, C.H., P.H. Wan, Y.Z. Lee, J.Y. Su, T. Lai, C.L. Chang, and Y.T. Liu. "Some Phenomena of Spatial Interaction in the Networked Spaces." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 039-47. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. As a result of the network-based nature of Internet and communications technologies, a new spatial form, which is defined as networked spaces by this research, is emerging. This paper provides a significant theoretical framework to unpack complex spatial relationships caused by the networked spaces. Such emerging design approach challenges the design thinking, design process and design knowledge of architecture, urban design, as well as media design.
Fischer, Thomas, Christiane Herr, Mark Burry, and John Frazer. "Tangible Interfaces to Explain Gaudi's Use of Ruled-Surface Geometries: Interactive Systems Design for Haptic, Non-verbal Learning."

The first part discusses the modelling methods underlying the columns of the cathedral and the techniques required to translate them into built structures. The second part discusses the design and development of a tangible machine-readable model to explain column-modelling methods interactively in educational contexts such as art exhibitions. It is designed to explain the principles underlying the column design by means of physical interaction without using mathematical terms or language.
Russell, Peter. "Teaching Concurrent Engineering Using Intensive Interdisciplinary Robotic Workshops." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 361-368. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. The métier of architecture is, contrary to the myth of the single visionary architect, one of co-ordinated interdisciplinary teamwork. For students of architecture, this concept can be somewhat abstract without the chance for hands-on experience in working in such teams. The authors contend that this type of co-operation is better trained than taught. As a consequence, the authors have sought to create a pedagogical framework for training interdisciplinary work: Furthermore, by using assignments that call for concurrent engineering, the framework allows students to understand the complexities of integrated planning practices. The paper explains the methods and results of workshops carried out at two Universities over the past one and one-half years. Students are arranged in small teams of 3-5 students consisting optimally of architects, engineers and computer programmers. The assignment is to build and program a robot to successfully execute a prescribed set of objectives. The 10- day workshop is carried out as a competition in order to accelerate the development process and to focus the design work to a specific goal. 
Rizal, H., and Ahmad Rafi Moham Eshaq. "The Impact of Internet Enabled Computer Aided Design (iCAD) in Construction Industry." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 085-92. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. The advent of the Internet has opened up and given, particularly, the developing countries and the world in general, a transformation into collective intelligence (Levy, 1998) societies linked to digital communication (Rafi, 2001). Apart from large corporations, the rapid evolution of border-less communication has also synergise between the art and science expertise to form low-cost internet-based networks that have become multi-million dollar companies within a short period of time (e.g. Linux) (Rafi, 2001). In the context of architectural designs and construction industries, the birth of Internet-based CAD (iCAD) solutions has offered a new dimension to architectural practice. The function of CAD has expanded as a tool to communicate and collaborate as well as to better control all phases of the architectural practices. This paper will review the current available iCAD tools and explore the possible utilisation of iCAD in architectural practices. The opportunities for modifying current professional practice standards to best use iCAD will be rationalised as well as the elements in ensuring the effectiveness of iCAD implementation. The final component of the paper will be an evaluation framework to measure the value of iCAD in an architectural practice. The framework will become an early platform for an architectural practice to decide and plan their future in utilising and applying iCAD in the most efficient way.

This paper introduces knowledge management and computer aided visualisation as a key in establishing both valuation and value creation capabilities in the enterprise where dissemination of knowledge and effective sharing of information through collaboration spur creativity and stimulate business practices. The paper draws an original approach for the design and development of a universal information/knowledge visualisation tool and outlines the mechanics that enable the working prototype that focuses on CAD.
Simpson, M.R.. "The Virtual Designer: the Application of VRML to Collaborative Design." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 183-190. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. At present the architectural design process contains many inefficiencies. The tools of the collaborative design process tend to lack the high levels of interaction and communication required. All approaches in the modern design profession point to the utilisation of virtual space to maintain effective collaboration on all production levels. It is no longer relevant for outdated forms of physical communication to be expected to provide optimum collaborative work in the digital era. A new approach is needed. Rather than redesigning the process, the alteration of how communication between team members occurs is more appropriate.
Wu, S., H. Ghenniwa, and W. Shen. "User Model of a Personal Assistant in Collaborative Design Environments." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 39-54. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. During the past decade, intelligent agents have been applied in attempts to a number of collaborative engineering design systems. Intelligent interface agents or personal assistants play a very important role in such systems. A fundamental issue in designing a personal assistant is how to build adequate models of the user and the domain. This paper proposes a cognitive user model of a personal assistant in collaborative design environments, which comprises a user interest model, a user behaviour model, an inference component and a collaboration component. These models and components can help agents effectively achieve the user's goals. The proposed user model is being implemented in a coordinated, intelligent, rational agent (CIR-Agent) model on a FIPA-compliant platform. A case study in a multidisciplinary design optimization (MDO) software environment is also presented.
Rashid, Hani, and Lise Couture. "Virtual Architecture - Real Space." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 005-8. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. We are in the very early stages of a digital revolution whose direction we will not be certain of for sometime, much in the same way that Enlightenment-era architects, theologians, and thinkers did not quite comprehend the profound changes taking place in their own time. Todayis digital technologies are having profound effects on many different aspects of our contemporary understanding from the human genome to the mapping of the cosmos. Digital manipulations that use virtual-reality technologies form a major part of this revolution. As architects we are responding in a number of ways, by conceiving of entirely new geometric principles, new methodologies, and entirely novel approaches to representation beyond perspectival geometry.
Paranandi, M., and T. Sarawgi. "Virtual Reality on Architecture: Enabling Possibilities." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 309-316. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. This paper examines the potential of Virtual Reality (VR) technologies for architectural applications. There has been a great deal of anticipation for its implications for architecture since Ivan Sutherland's first VR system in the 60's. The term VR was formalized and became popular in the main stream in the late 80's and became an industry by the late 90's. Although it has found good applications in Medicine, Flight Simulation, and Video Game Industry, its effect on architecture remains imperceptible. In the work that we review, we found that the success of VR in architecture has primarily been in the passive and exploratory applications. We also note that at the present time, the cost of VR systems is directly proportionate to the level of photorealism and immersion. We contend that photorealistic visualization and total immersion are not absolute prerequisites for making most design decisions. Hence, through this paper we bring to light the inherent promise of VR technology and the potential impact it could have with its current limitations, on the way we conventionally think and design our built environment pushing it beyond space and time constraints.
Neuckermans, Herman, A. Heylighen, and P. Morisse. "Visual Keys to Architectural Design." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 175-182. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. This paper presents a new mechanism to access and interact with DYNAMO, a collective case base for architectural design developed as a Web-based tool. The system is fully operational since a few years in the context of architectural design education as well as for seminars on architectural theory. We have now developed a set of visual keys structured at the one hand according to the Vitruvian tripartition of architecture: Firmitas (structure, materials,), Utilitas (building programme,), Venustas (formal qualities/articulation, spatial configuration,) to which we added Context (topography, site, budget, climate,...) as a supplementary dimension, and at the other hand including three levels of detail: single spaces, building blocks or master plan entities. Visual keys match the architectis designerly way of thinking. The visual keys are in fact nothing else than a graphical codification of architecture within the realm of architectural composition. The software, that has been developed so far, does not only allow users to access cases via the keys we have implemented, but it also provides a tool to sketch and submit their own keys.
Huang, Y.H.. "What Designers See from a Case? a Cognitive Approach." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 167-174. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. In the behaviour 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.
Korolczuk, Danuta, and Jaroslaw Szewczyk. "XML Schema for Investigation on Polish Traditional Rural Architecture." In Proceedings of the 7th International Conference on Computer-Aided Architectural Design Research in Asia, 49-56. CAADRIA. Cyberjaya, Malaysia: Multimedia University Malaysia, 2002. The XML is a perfect tool for scientific data management and analyses, because of its potential as a language for representation of structured graphical information stored in object-relational databases. The paper discusses the development process of the architectural database, defined by the XML Schema definitions (RuralXML). The database is being created in order to describe Polish traditional rural architecture for scientific investigations of architectural, rural and spatial planning fields.
