summary	This work presents the pedagogical experience of a Design Workshop that investigated the impact of the digital and analogic means on the architectonic design process This work was based on the research of Dr. Arch. Julio BermÝdez who also directed this workshop in 1997. This class was part of the Training Program organized by the "Centro de Informatica y Diseho" (CID) at the "Universidad Nacional del Litoral" FADU (Facultad de Arquitectura Diseho y Urbanismo) Santa Fe, Argentina and made possible by the ongoing International Program of Academic Exchange between the FADU and the (University of Utah Graduate School of Architecture (IPAE Project NO 4). The experimental studio utilized an architectural problem to study the procedural, technical, interpretative and theoretical issues associated with the relationship of contemporary media and design process. The pedagogical vehicle was a program that expresses in itself the meeting or collision between two cultures competing for dominance at the end of the millennium: the immemorial material culture (corporeal, tectonic) and the new and everyday more influent virtual culture (information, nets, media, simulation). The premise for the design process, communication and criticism was the constant migration between the digital and analog representation systems. Within this theoretical-practical context semantic aspects containing different representation modalities were used such as physical and electronic models along with systematic and sensitive drawings (manuals, pixels and with CAD). Hybrid interfaces took a leading role in the process since they allowed the communication between analog and digital media through the creative and technical interaction between scanner, video and computer. This architectural and media context generated an intense pedagogic environment fostering the development of creativity and a critical attitude while allowing concrete breakthroughs in the teaching process and format design. Our work reflects on these results showing examples of stud-go works and providing a final evaluation of this unique experience in Argentina.

title	Generic representations : an approach for modelling procedural and declarative knowledge of building types in architectural design
source	Eindhoven University of Technology
summary	The building type is a knowledge structure that is recognised as an important element in the architectural design process. For an architect, the type provides information about norms, layout, appearance, etc. of the kind of building that is being designed. Questions that seem unresolved about (computational) approaches to building types are the relationship between the many kinds of instances that are generally recognised as belonging to a particular building type, the way a type can deal with varying briefs (or with mixed use), and how a type can accommodate different sites. Approaches that aim to model building types as data structures of interrelated variables (so-called ‘prototypes’) face problems clarifying these questions. The research work at hand proposes to investigate the role of knowledge associated with building types in the design process.Knowledge of the building type must be represented during the design process. Therefore, it is necessary to find a representation which supports design decisions, supports the changes and transformations of the design during the design process, encompasses knowledge of the design task, and which relates to the way architects design. It is proposed in the research work that graphic representations can be used as a medium to encode knowledge of the building type. This is possible if they consistently encode the things they represent; if their knowledge content can be derived, and if they are versatile enough to support a design process of a building belonging to a type.A graphic representation consists of graphic entities such as vertices, lines, planes, shapes, symbols, etc. Establishing a graphic representation implies making design decisions with respect to these entities. Therefore it is necessary to identify the elements of the graphic representation that play a role in decision making. An approach based on the concept of ‘graphic units’ is developed. A graphic unit is a particular set of graphic entities that has some constant meaning. Examples are: zone, circulation scheme, axial system, and contour. Each graphic unit implies a particular kind of design decision (e.g. functional areas, system of circulation, spatial organisation, and layout of the building). By differentiating between appearance and meaning, it is possible to define the graphic unit relatively shape-independent.If a number of graphic representations have the same graphic units, they deal with the same kind of design decisions. Graphic representations that have such a specifically defined knowledge content are called ‘generic representations.’ An analysis of over 220 graphic representations in the literature on architecture results in 24 graphic units and 50 generic representations. For each generic representation the design decisions are identified. These decisions are informed by the nature of the design task at hand. If the design task is a building belonging to a building type, then knowledge of the building type is required. In a single generic representation knowledge of norms, rules, and principles associated with the building type are used. Therefore, a single generic representation encodes declarative knowledge of the building type. A sequence of generic representations encodes a series of design decisions which are informed by the design task. If the design task is a building type, then procedural knowledge of the building type is used.By means of the graphic unit and generic representation, it is possible to identify a number of relations that determine sequences of generic representations. These relations are: additional graphic units, themes of generic representations, and successive graphic units. Additional graphic units defines subsequent generic representations by adding a new graphic unit. Themes of generic representations defines groups of generic representations that deal with the same kind of design decisions. Successive graphic units defines preconditions for subsequent or previous generic representations. On the basis of themes it is possible to define six general sequences of generic representations. On the basis of additional and successive graphic units it is possible to define sequences of generic representations in themes. On the basis of these sequences, one particular sequence of 23 generic representations is defined.The particular sequence of generic representations structures the decision process of a building type. In order to test this assertion, the particular sequence is applied to the office building type. For each generic representation, it is possible to establish a graphic representation that follows the definition of the graphic units and to apply the required statements from the office building knowledge base. The application results in a sequence of graphic representations that particularises an office building design.Implementation of seven generic representations in a computer aided design system demonstrates the use of generic representations for design support. The set is large enough to provide additional weight to the conclusion that generic representations map declarative and procedural knowledge of the building type.

title	Generic Representations - Typical Design without the Use of Types
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 117-133
summary	The building type is a (knowledge) structure that is both recognised as a constitutive cognitive element of human thought and as a constitutive computational element in CAAD systems. Questions that seem unresolved up to now about computational approaches to building types are the relationship between the various instances that are generally recognised as belonging to a particular building type, the way a type can deal with varying briefs (or with mixed functional use), and how a type can accommodate different sites. Approaches that aim to model building types as data structures of interrelated variables (so-called 'prototypes') face problems clarifying these questions. It is proposed in this research not to focus on a definition of 'type,' but rather to investigate the role of knowledge connected to building types in the design process. The basic proposition is that the graphic representations used to represent the state of the design object throughout the design process can be used as a medium to encode knowledge of the building type. This proposition claims that graphic representations consistently encode the things they represent, that it is possible to derive the knowledge content of graphic representations, and that there is enough diversity within graphic representations to support a design process of a building belonging to a type. In order to substantiate these claims, it is necessary to analyse graphic representations. In the research work, an approach based on the notion of 'graphic units' is developed. The graphic unit is defined and the analysis of graphic representations on the basis of the graphic unit is demonstrated. This analysis brings forward the knowledge content of single graphic representations. Such knowledge content is declarative knowledge. The graphic unit also provides the means to articulate the transition from one graphic representation to another graphic representation. Such transitions encode procedural knowledge. The principles of a sequence of generic representations are discussed and it is demonstrated how a particular type - the office building type - is implemented in the theoretical work. Computational work on implementation part of a sequence of generic representations of the office building type is discussed. The paper ends with a summary and future work.

title	Implementation of IT and CAD - what can Architect schools do?
source	AVOCAAD First International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-01-09] Brussels (Belgium) 10-12 April 1997, pp. 83-92
summary	In Sweden representatives from the Construction industry have put forward a research and development program called: "IT-Bygg 2002 -Implementation". It aims at making IT the vehicle for decreasing the building costs and at the same time getting better quality and efficiency out of the industry. A seminar was held with some of the most experienced researchers, developers and practitioners of CAD in construction in Sweden. The activities were recorded and annotated, analysed and put together afterwards; then presented to the participants to agree on. Co-operation is the key to get to the goals - IT and CAD are just the means to improve it. Co-operation in a phase of implementation is enough problematic without the technical difficulties in using computer programs created by the computer industry primarily for commercial reasons. The suggestion is that cooperation between software companies within Sweden will make a greater market to share than the sum of all individual efforts. In the short term, 2 - 5 years, implementation of CAD and IT will demand a large amount of educational efforts from all actors in the construction process. In the process of today the architect is looked upon as a natural coordinator of the design phase. In the integrated process the architect's methods and knowledge are central and must be spread to other categories of actors - what a challenge! At least in Sweden the number of researchers and educators in CAAD is easily counted. How do we make the most of it?

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 136-143.
summary	The hybridization of architectural, biological and robotic agencies Situated in the field of architectural biodesign, InterspeciesForms explores a closer relationship between the fungus Pleurotus ostreatus and the designer in the creation of form. The intention of hybridizing mycelia’s agency of growth with architectural design intention is to generate novel, non-indexical crossbred designed outcomes that evolve preconceived notions of architectural form. Mycelium are threadlike fibrous root systems made up of hyphae, that form the vegetative part of a fungus (Jones 2020). Known as the hackers of the wood wide web (Simard 1997) mycelia form complex symbiotic relationships with other species that inhabit our earth. Michael Lim states “Fungi redefine resourcefulness, collaboration, resilience and symbiosis” (Lim 2022, p. 14). When wandering around the forest to connect with other species or searching for food, fungi form elaborate and entangled networks by spreading their hyphal tips. Shown in Figure 1, this living labyrinth results in the aesthetic formation of an intricate web. Due to the organisms ability to determine the most effective direction of growth, communicate with its surrounding ecosystem, and connect with other species, fungi are indeed an intelligent species with a unique aesthetic that must not be ignored. In drawing on these concepts, I refer to the organism’s ability to search for, tangle, and digest its surroundings as ‘mycelia agency of growth’. It is this specific behavioral characteristic that is the focus of this research, with which I, as the architect, set out to co-create and hybridize with.

title	Evaluating intelligent buildings according to level of service systems integration
source	Automation in Construction 6 (5-6) (1997) pp. 471-479
summary	The intelligent building is supposed to provide the environment and means for an optimal utilization of the building, according to its designation. This extended function of a building can be achieved only by means of an extensive use of building service systems, such as HVAC; electric power; communication; safety and security; transportation; sanitation, etc. Building intelligence is not related to the sophistication of service systems in a building, but rather to the integration among the various service systems, and between the systems and the building structure. Systems' integration can be accomplished through teamwork planning of the building, starting at the initial design stages of the building. This paper examines some existing buildings claimed to be "intelligent", according to their level of systems' integration.

source	ACADIA ‘99 Proceedings / ISBN 1-880250-08-X / Salt Lake City 29-31 October 1999, 353 p.
summary	Throughout known architectural history, representation, media and design have been recognized to have a close relationship. This relationship is inseparable; representation being a means for engaging in design thinking and making and this activity requiring media. Interpretations as to what exactly this relationship is or means have been subject to debate, disagreement and change along the ages. Whereas much has been said about the interactions between representation and design, little has been elaborated on the relationship between media and design. Perhaps, it is not until now, surrounded by all kinds of media at the turn of the millennium, as Johnson argues (1997), that we have enough context to be able to see and address the relationship between media and human activities with some degree of perspective.

title	Some Experimental Results in the Assessment of Architectural Media
doi	https://doi.org/10.52842/conf.acadia.2000.163
source	Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 163-171
summary	The relationship between the media and architectural design can be an important factor and can influence the design outcome. However, the nature, direction and magnitude of this relationship are unknown. Consequently, there have been many speculative claims about this relationship and almost none of them are supported with empirical research studies. In order to investigate these claims and to provide a testable framework for their potential contributions to architectural education, this study aims to explore the effects of media on architectural design. During 1995-1997, a total of 90 students enrolling in First Year Design Studio and Introduction to Computing classes at Georgia Tech participated in the study. A set of quantitative measures was developed to assess the differences between the two media and the effects on the architectural design. The results suggested that media influenced certain aspects of students’ designs. It is concluded that there is a strong relationship between the media and architectural design. The type of media not only changes some quantifiable design parameters but also affects the quality of design.

title	Toward New Wall Systems: Lighter, Stronger, Versatile

summary	Recent developments in digital technologies and smart materials have created new opportunities and are suggesting significant changes in the way we design and build architecture. Traditionally, however, there has always been a gap between the new technologies and their applications into other areas. Even though, most technological innovations hold the promise to transform the building industry and the architecture within, and although, there have been some limited attempts in this area recently; to date architecture has failed to utilize the vast amount of accumulated technological knowledge and innovations to significantly transform the industry. Consequently, the applications of new technologies to architecture remain remote and inadequate. One of the main reasons of this problem is economical. Architecture is still seen and operated as a sub-service to the Construction industry and it does not seem to be feasible to apply recent innovations in Building Technology area. Another reason lies at the heart of architectural education. Architectural education does not follow technological innovations (Watson 1997), and that “design and technology issues are trivialized by their segregation from one another” (Fernandez 2004). The final reason is practicality and this one is partially related to the previous reasons. The history of architecture is full of visions for revolutionizing building technology, ideas that failed to achieve commercial practicality. Although, there have been some adaptations in this area recently, the improvements in architecture reflect only incremental progress, not the significant discoveries needed to transform the industry. However, architectural innovations and movements have often been generated by the advances of building materials, such as the impact of steel in the last and reinforced concrete in this century. There have been some scattered attempts of the creation of new materials and systems but currently they are mainly used for limited remote applications and mostly for aesthetic purposes. We believe a new architectural material class is needed which will merge digital and material technologies, embedded in architectural spaces and play a significant role in the way we use and experience architecture. As a principle element of architecture, technology has allowed for the wall to become an increasingly dynamic component of the built environment. The traditional connotations and objectives related to the wall are being redefined: static becomes fluid, opaque becomes transparent, barrier becomes filter and boundary becomes borderless. Combining smart materials, intelligent systems, engineering, and art can create a component that does not just support and define but significantly enhances the architectural space. This paper presents an ongoing research project about the development of new class of architectural wall system by incorporating distributed sensors and macroelectronics directly into the building environment. This type of composite, which is a representative example of an even broader class of smart architectural material, has the potential to change the design and function of an architectural structure or living environment. As of today, this kind of composite does not exist. Once completed, this will be the first technology on its own. We believe this study will lay the fundamental groundwork for a new paradigm in surface engineering that may be of considerable significance in architecture, building and construction industry, and materials science.

title	RealSpace in QuickTimes: architecture and digitization
source	Rotterdam: Nai Publishers
summary	Time and space, drastically compressed by the computer, have become interchangeable. Time is compressed in that once everything has been reduced to 'bits' of information, it becomes simultaneously accessible. Space is compressed in that once everything has been reduced to 'bits' of information, it can be conveyed from A to B with the speed of light. As a result of digitization, everything is in the here and now. Before very long, the whole world will be on disk. Salvation is but a modem away. The digitization process is often seen in terms of (information) technology. That is to say, one hears a lot of talk about the digital media, about computer hardware, about the modem, mobile phone, dictaphone, remote control, buzzer, data glove and the cable or satellite links in between. Besides, our heads are spinning from the progress made in the field of software, in which multimedia applications, with their integration of text, image and sound, especially attract our attention. But digitization is not just a question of technology, it also involves a cultural reorganization. The question is not just what the cultural implications of digitization will be, but also why our culture should give rise to digitization in the first place. Culture is not simply a function of technology; the reverse is surely also true. Anyone who thinks about cultural implications, is interested in the effects of the computer. And indeed, those effects are overwhelming, providing enough material for endless speculation. The digital paradigm will entail a new image of humankind and a further dilution of the notion of social perfectibility; it will create new notions of time and space, a new concept of cause and effect and of hierarchy, a different sort of public sphere, a new view of matter, and so on. In the process it will indubitably alter our environment. Offices, shopping centres, dockyards, schools, hospitals, prisons, cultural institutions, even the private domain of the home: all the familiar design types will be up for review. Fascinated, we watch how the new wave accelerates the process of social change. The most popular sport nowadays is 'surfing' - because everyone is keen to display their grasp of dirty realism. But there is another way of looking at it: under what sort of circumstances is the process of digitization actually taking place? What conditions do we provide that enable technology to exert the influence it does? This is a perspective that leaves room for individual and collective responsibility. Technology is not some inevitable process sweeping history along in a dynamics of its own. Rather, it is the result of choices we ourselves make and these choices can be debated in a way that is rarely done at present: digitization thanks to or in spite of human culture, that is the question. In addition to the distinction between culture as the cause or the effect of digitization, there are a number of other distinctions that are accentuated by the computer. The best known and most widely reported is the generation gap. It is certainly stretching things a bit to write off everybody over the age of 35, as sometimes happens, but there is no getting around the fact that for a large group of people digitization simply does not exist. Anyone who has been in the bit business for a few years can't help noticing that mum and dad are living in a different place altogether. (But they, at least, still have a sense of place!) In addition to this, it is gradually becoming clear that the age-old distinction between market and individual interests are still relevant in the digital era. On the one hand, the advance of cybernetics is determined by the laws of the marketplace which this capital-intensive industry must satisfy. Increased efficiency, labour productivity and cost-effectiveness play a leading role. The consumer market is chiefly interested in what is 'marketable': info- and edutainment. On the other hand, an increasing number of people are not prepared to wait for what the market has to offer them. They set to work on their own, appropriate networks and software programs, create their own domains in cyberspace, domains that are free from the principle whereby the computer simply reproduces the old world, only faster and better. Here it is possible to create a different world, one that has never existed before. One, in which the Other finds a place. The computer works out a new paradigm for these creative spirits. In all these distinctions, architecture plays a key role. Owing to its many-sidedness, it excludes nothing and no one in advance. It is faced with the prospect of historic changes yet it has also created the preconditions for a digital culture. It is geared to the future, but has had plenty of experience with eternity. Owing to its status as the most expensive of arts, it is bound hand and foot to the laws of the marketplace. Yet it retains its capacity to provide scope for creativity and innovation, a margin of action that is free from standardization and regulation. The aim of RealSpace in QuickTimes is to show that the discipline of designing buildings, cities and landscapes is not only a exemplary illustration of the digital era but that it also provides scope for both collective and individual activity. It is not just architecture's charter that has been changed by the computer, but also its mandate. RealSpace in QuickTimes consists of an exhibition and an essay.

title	Narrowing the Gap Between CAAD and Computer Programming: A Re-Examination of the Relationship Between Architects as Computer-Based Designers and Software Engineers, Authors of the CAAD Environment
doi	https://doi.org/10.52842/conf.caadria.1997.491
source	CAADRIA ‘97 [Proceedings of the Second Conference on Computer Aided Architectural Design Research in Asia / ISBN 957-575-057-8] Taiwan 17-19 April 1997, pp. 491-498
summary	As the interfaces between computer users and computer programs become more friendly, the gap between the architect as designer and the software engineer as strategist increases: the designer is even less inclined to relate to the internal workings of the computer program. One intention of the friendly interface is to allow greater access to relatively sophisticated programs for people to whom the computer is not a natural ally. But with tailor-made software comes the paradox of unintended perspective use. This paper discusses the need for design architects to learn basic programming skills in a contemporary context in order to avoid being inadvertently restricted by a software apparent flexibility. An undergraduate course that sets out to familiarise students with the new possibilities is presented here in detail.

source	Coyne, R. Ramscar, M. Lee, J. and Zreik, K. (eds.) Design and the net. Proceedings of the Sixth International EuropIA Conference, Europia Productions, Paris, pp. 39-52
summary	This paper briefly describes the implementation of an Internet-intranet information system applied to a large-scale project. The large-scale project is centered on the urban area around the Porta Susa railway station in Turin, Italy. The information system integrates the communicative tools used to facilitate and improve the collaboration between the different actors working on the project and the distributed environment used to elaborate the information across a wide area network. The main factors considered are those which exploit the potentialities of computers and networks for interaction and communication. One result is the possibility of interacting dynamically with the information, re-elaborating and distributing it in progress. The information systems opens different ways of collaboration between the project employees, and extends the participation in the project to the citizens.

title	SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.
source	Proceedings of Collaborative Decision-Support Systems Focus Symposium, 30th July, 2002; under the auspices of InterSymp-2002, 14° International Conference on Systems Research, Informatics and Cybernetics, 2002, Baden-Baden, pg. 27-44.
summary	The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article. Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components. Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article. Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components. Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

title	On Architectural Design of Virtual Environments
source	Design Studies, Vol.18, No. 2, 143-154
summary	This paper considers the domains of architectural design and film theory for the purpose of informing the design of virtual environments (VEs). It is suggested that these domains may form a background for the consideration of possible metaphors for the design of VEs. Firstly, the paper investigates the relation between architecture and virtual reality technology, through the nature of drawings and virtual environments as means of representing three-dimensional spaces. Then, differences between VEs and physical environments (PEs) are identified for the purpose of understanding the intrinsic nature of VEs, by comparing them to our familiar everyday spatial experience. This step is considered essential in helping us understand how we might be able to develop an architectural conception of designing spaces, in the context of VEs. The paper then presents two directions towards informing VE design by means of theoretical and practical architectural design knowledge. Finally, the use of film-related studies is considered as a means of enhancing our conception of time and movement in VEs.

title	A digital Procedure of Building Construction: A practical project

summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

summary	Design cases were considered as the design solution or condensed knowledge of design experience. In the analogical reasoning process, case adaptation is the fundamental task for solving the problem. This paper is aimed to study the difference between human designers and computers in case adaptation. Two design experiments are undertaken for examining how designers apply dimensional and topological adaptation, exploring the difference of case adaptation by novice and experienced designers, and examining the difference between human judgement in case adaptation and the evaluation mechanism by providing similarity assessment. In conclusion, this study provides the comparative analysis from the above observation and implications on the development of case-based reasoning systems for designers.

title	Multi-sensory user interface for a virtual-reality-based computer-aided design system
source	Computer-Aided Design, Vol. 29 (10) (1997) pp. 709-725
summary	The generation of geometric shapes called `geometric concept designs' via the multi-sensory user interface of a virtual reality (VR) based system motivates the currentresearch. In this new VR-based system, geometric designs can be more effectively inputted into the computer in a physically intuitive way. The interaction mechanism issimilar to the way in which industrial designers sit and discuss concept design shapes across a table from each other, prior to making a final decision about the productdetails. By using different sensory modalities, such as voice, hand motions and gestures, product designers can convey design ideas through the VR-basedcomputer-aided design (CAD) system. In this scenario, the multi-sensory interface between human and computer plays a central role with respect to usability, usefulnessand accuracy. The current paper focuses on determining the requirements for the multi-sensory user interface and assessing the applications of different input and outputmechanisms in the virtual environment (VE). In order to evaluate this multi-sensory user interface, this paper formulates the typical activities in product shape design intoa set of requirements for the VR-CAD system. On the basis of these requirements, we interviewed typical CAD users about the effectiveness of using different sensoryinput and output interaction mechanisms such as visual, auditory and tactile. According to the results of these investigations, a nodal network of design activity thatdefines the multi-sensory user interface of the VR-CAD system is determined in the current research. The VR-CAD system is still being developed. However, voicecommand input, hand motion input, three-dimensional visual output and auditory output have been successfully integrated into the current system. Moreover, severalmechanical parts have been successfully created through the VR interface. Once designers use the VR-CAD system that we are currently developing, the interfacerequirements determined in the current paper may be verified or refined. The objectives of the current research are to expand the frontiers of product design and establisha new paradigm for the VR-based conceptual shape design system.

title	On the linguistic nature of Cyberspace and Virtual Communities
source	CM Special Journal Issue. Edited by Dave Snowdon, Nottingham: Submitted
summary	This paper argues for a linguistic explanation of the nature of Virtual Communities. Virtual Communities develop and grow in electronic space, or 'cyberspace'. Authors such as Benedikt Meyrowitz and Mitchell have theorised about the nature of electronic space whilst Lefebvre, Popper, Hakim Bey (aka Lamborn Wilson) and Kuhn have theorised more generally about the nature of space. Extending this tradition and the works of these authors, this paper presents a language based perspective on the nature of electronic spaces. Behaviour in cyberspace is based on and regulated by hardware, software tools and interfaces. A definition of electronic space cannot be given beyond its linguistic characteristics, which underlie and sustain it. The author believes that the more users and developers understand the relationship between language and cyberspace, the more they will be able to use specific metaphors for dwelling and inhabiting it. In particular, MUDs/MOOs and the Web are interesting places for testing and observing social behaviours and dynamics.
