summary Twenty years of revolution, from the middle '70 to the middle '90. Many things have changed since the origins of computer graphics and computer aided design in architecture. We started teaching drafting on terminals which connected to mini computers, complex procedures or sets of graphics libraries working with keywords, vectors and storage screens. The next step was devoted to the discovery of workstations in the early '80's, where the user sat face on to the whole power of a multitasking system. At that time to use up to 16 time sharing processes running on the same work station seemed to have no practical use at all. Fortunately someone (ie Xerox PARC laboratories) at the same time started to develop the so-called GUI. Graphical user interface started a revolution in human/machine interface (ie Smalltalk). The desktop metaphor, the use of multiple windows and dialogues joined with icons and pop up menus let the user manage more applications and, even more important, created a standard in application/user interface (CUA). In the meantime focus had moved from hardware to software, systems being chosen from the software running. The true revolution we have seen starting from that base and involving an ever increasing number of users was the birth of PC based applications for CAAD. Generally speaking nowadays there are three main technologies concerning teaching: communication, multimedia and virtual reality. The first is the real base for future revolution. In the recent past we have started to learn how to manage information by computers. Now we can start to communicate and share information all over the world in real time. The new age opened by fax, followed by personal communication systems and networks is the entry point for a real revolution. We can work in the virtual office, meet in virtual space and cooperate in workgroups. ATM and ISDN based teleconferencing will provide a real working tool for many. The ever increasing number of e-mail addresses and network connections is carrying us towards the so called 'global village'. The future merger between personal digital assistant and personal communication will be fascinating. Multi & HyperMedia technology is, like a part of VR, a powerful way to share and transfer information in a structured form. We do not need to put things in a serial form removing links because we can transfer knowledge as is. Another interesting and fundamental aspect typical of VR applications is the capability to change cognitive processes from secondary (symbolic - reconstructive) to primary (perceptive - motory). In this way we can learn by direct experience, by experiment as opposed to reading books. All these things will affect not only ways of working but also ways of studying and teaching. Digital communications, multimedia and VR will help students, multimedia titles will provide different kinds of information directly at home using text, images, video clips and sounds. Obviously all those things will not substitute human relationship as a multimedia title does not compete against a book but it helps.

title GIS: Science or Tool - The Built Environment Perspective
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary This paper attempts to locate GIS in the context of the built environment professions, rather than in the context of computer science, recognizing the integrated but limiting approach of viewingGIS from a strictly computer / spatial science perspective. The paper reviews the conflicts and tensions appearing in the GIS debate seeing them as reflecting the differences between the perceptions and interests of software developers and those of the professions. The "spatial science versus professional tool" dilemma is therefore critically assessed. Science is identified as the dominant paradigm within which GIS development has taken place. This encompasses the emphasis on GIS as spatial science; the interest in particular forms of spatial analysis; a narrow approach to the idea of information; the debate about the appropriate emphasis on the location for GIS in undergraduate education. The interests and activities of the professions cannot be encompassed within the pre-existing science paradigm. The paper identifies the interest the professions have had in broad geographical issues (as distinct from narrow spatial issues). It recognizes the different conventions and procedures used in recording and using geographical information, not all of them objective or scientific. It views the computer, not as a "scientific engine", but as a modern medium for representing and analyzing information. This includes storage and analysis, both internally (algorithmic manipulation) and outside (qualitative manipulation, beyond formal -"computer"- logic). This approach suggests a framework for research of a nature more sympathetic to the needs of the built environment professions in particular and an agenda which would include an examination of: (i) the conventions and procedures used in the professions to collect, store and process information and how these translate to computer technology; (ii) the types of software used and the way procedures may be accommodated by combining and integrating packages; (iii) the dynamism of GIS development (terms such as "dedicated", "mainframe", "PC-based", "distributed", "pseudo-", etc. are identified as indicativeof the need for professions-based approaches to GIS development); (iv) a critique of "information" (modelling of information flows within the professions, may yield valuable insights into the (modelling of information flows within the professions , may yield valuable insights into the similarity of requirements for a variety of "workplace scenarios").

title A digital Procedure of Building Construction: A practical project
source AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
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 This project was an investigation into the application of Urban Information Systems [UIS] based on 3-Dimensional computer models. The research centred on a collaboration between the Architecture and Buildings Aids Computer Unit, Strathclyde [ABACUS] and the Edinburgh Old Town Renewal Trust [EOTRT] to develop a detailed computer model of Edinburgh's old town. The area of particular interest is the development of an interface to a database of property related information. This provides a means of analysing the multi-layered and multi-dimensional spatial data which is characteristic of urban environments. The research also investigated how, by using multi media technology as a data integration tool , urban models could be used to improve decision making in the framework of urban management.

title Sun and Time in the Built Environment
source The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, p. 248
doi https://doi.org/10.52842/conf.ecaade.1994.x.f4j
summary At a time when requirements on the quality of the built environment are increasingly becoming explicit and specific, computer technology promises the ability to analyse and evaluate buildings during the design process. The computer can extract the necessary information from conventional geometric representations, generate comprehensive descriptions of the aspects to be analysed and use these to arrive at precise and accurate results that can be represented visually. Visual representations facilitate comprehension of the analyses and of their results because of their agreement with our predominantly visual perception of the built environment. The consequent close correspondences between geometric design representations and the visual representation of analyses and evaluations allow direct correlation of the results with the design as a whole. Such correlation is instrumental for imposing explicit and justifiable constraints on the further development of a design. One good example of visual analyses is daylighting. In many drafting and modelling programs a viewing point can be set on the basis the sun’s height and azimuth. The projection returned reveals the surfaces that are directly lit by the sun. In other programs the sun’s height and azimuth can be used to position a light source with parallel rays. This source gives rise to shading and shadows that correspond to the ones produced by the sun. In addition, several programs can calculate the position of the sun and hence the viewing point or the light source on the basis of the date, the time and the geographic coordinates of the place. The availability of computer-aided daylighting analysis has obvious advantages for practice. Efficiency and reliability of the analysis increase, while flexibility is superior to analog simulations. Unfortunately automation of daylighting analysis may also impede understanding of underlying principles, that is, of the issues at the focus of architectural education. Explaining how the analysis is performed and why becomes thus a necessity for computer-aided design education. Exercises that aim at more than just learning and using a computer program can enrich the student’s understanding of the analysis and its results. The efficiency and flexibility of the computer facilitate the study of aspects such as the comparison of local apparent time, local mean time, standard time and daylight saving time and their significance for daylighting, solar heating and cooling patterns and possibilities. Sundials with their explicit correspondence to solar movement can be instrumental in this respect. The efficiency and flexibility of the computer also support the investigation of the techniques by which the daylighting analysis is performed and explain the relationships between projective theory, sciagraphy and computer graphics. A better understanding of the principles and techniques for daylighting analysis has a generally positive influence on the students’ learning of the daylighting analysis software and more significantly on their correlation of daylighting constraints with their designs. This leads in turn to increased flexibility and adaptability of the designs with respect to daylighting and to a conscious and meaningful exploration of variations and alternative solutions.

summary The issue of monument protection and conservation not incidentally has become a part of the scope of interests of the Center for Computer Aided Architectural Design. As a research-educational division of the School of Architecture, Warsaw University of Technology, we are a partner providing advisory and implementation services. Employment of a large computer system such as Intergraph's MGE will constitute a considerable improvement for Conservation Offices in the introduction, storage, updating and accessibility of historical maps, photographs, information about information, geological and topological, network, roads, sites, CAD drawings and 3D models. Another important effect will be that of setting a direction for activities of other offices interested in increasing their work efficiency through computerization.

title Opening Doors at Harvard's Graduate School of Design
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Design communication has many forms and employs a wide array of references. Design pedagogy uses a rich body of sources and is informed by deep communication between faculty and student. Advancing technology for distribution and manipulation of digital design media and a pervasive computer network at the Harvard Graduate School of Design provide an ideal environment for investigating new methods of access to design resources. A research initiative called the DOORS project (Design-Oriented On-line Resource System) will make a variety of design reference materials available over the GSD's computer network Potentially, DOORS will provide access to: - the Frances Loeb Library's visual and special collections; - slides, drawings, photographs, videos; - private faculty slide collections; - maps and geographic information systems of text, numeric and other visual databases of three- dimensional computer models; - computer-generated animations and digital video segments with sound of multimedia projects. As early pilot versions of DOORS are released, faculty and students will gather visual information for study and modification, analyze images and models, compare and link design documentation in different formats, develop lectures and make presentations from computers in offices, classrooms, and studio work areas. Emphasis will be placed on flexibility, as this particular tool's success will hinge on its ability to respond to different approaches to design and instruction. DOORS proposes to offer three modalities, browsing, composition and presentation, to enable searching, organizati-on, and display. Using established library standards for record format, subject access and keyword indexing, browsing will offer flexible and diverse search criteria. Composition will provide tools for linking, annotation and manipulation of assembled materials. Individual presentations will be viewed in classrooms, studios or offices. A pilot project to assemble some of the basic technology and expertise required is currently under way. The objective of the pilot is to deliver a slice of material over the GSD's local area network in order to raise awareness of the tool's potential among faculty and students, to evaluate its effectiveness, and to formulate technical specifications for later project phases.

title Communicative Acts in Cooperative Architectural Design Environments
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The purpose of this paper is to present a scheme, that can be used to support the communication process in cooperative design. Computational aids for design have largely been for a designerworking by himself/herself. These aids have also been supplemented by the widespread use of artificial intelligence approaches. However, design is so complex, and very rarely acted upon by a single designer but many more working towards the same aim. This involves a new paradigm in which designers need to cooperate with each other using a computational medium. A protocol analysis in cooperative design has been carried out and technological support has been proposed.Cooperative design becomes an important paradigm for the next generation of intelligent computer aided design systems. It will be conducted in many forms among several designers and willrequire the support of advanced communication facilities beyond the "passive" transmission of data and messages. Technological advances in communication networks have opened up new ways for cooperative design interaction across several processes of cooperation among designers, designers and computer aided design systems, computer aided design systems and knowledge based systems, and knowledge based systems themselves. In cooperative design environments, aunit of communication among designers is the transfer of a message from one designer (a sender) to another (a receiver). The aim of such communication is to provide the receiver with some information or to have the receiver take certain actions. Inspired by the speech act theory, a branch of the philosophy of language and linguistics, such a unit is called a communicative act. By analogy to architectural design, a communicative act is a performing act in designers communication.

title Integration System for Urban Design from Planning Management to Visalization
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Advanced tools based on CAD or GIS systems and simulation methods have recently been introduced to support the many aspects of urban planning (design, analysis, evaluation, presentation). This research aims at constructing a system by integrating these support tools and linking GIS and simulation tools. The major purpose of this system are to manage the geographical data base of the target urban area, utilize the digital information of the area for planning and analysis,evaluate the impact of alternative proposals on the physical environment such as sunlight and daylight, visualize the results of analysis, and support the management of urban redevelopment /development projects. This paper shows some applications to illustrate usefulness of the system. These examples are concerned with a contemporary problem in urban planning of Tokyo: redevelopment of low-rise high-density residential districts and high-rise development in the central business districts. Urban redevelopment for the high-density urban areas in Japan requiresa evaluation of alternative plans by visualizing their environmental impact. This system enables the quantitative analysis of the environmental impact by using 3-dimensional geographical data andsimulation methods. In general, the merit and effect of planning support systems are recognized in terms of the "efficiency" of the planning process. The primary function of GIS is thought to bethe unification and management of various pieces of information. In addition, this research indicates the effectiveness of the integrated system in terms of utilizing the geographical information and visualizing the image of the future environment.

title An Overview of the PHIDIAS II HyperCAD System
source Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 63-74
doi https://doi.org/10.52842/conf.acadia.1994.063
summary The PHIDIAS II HyperCAD system combines the functionality of CAD graphics, hypermedia, database management and knowledge-based computation in a single, highly integrated design environment. The CAD functionality includes both 3-D and 2-D vector graphics. The hypermedia includes support for text, raster images, video and sound. The database management enables persistent storage and interlinking of large collections of text, images, video, sound and vector graphics, i.e., thousands of vector graphic objects and drawings in a single database. Retrieval is provided both through use of "associative indexing" based on hyperlinks and through use of an advanced query language. The knowledge- based computation includes both inference and knowledgebased critiquing.

A highly unusual feature of PHIDIAS II is that it implements all of its functions using only hypermedia mechanisms. Complex vector graphic drawings and objects are represented as composite hypermedia nodes. Inference and critiquing are implemented through use of what are known as virtual structures [Halasz 1988], including virtual links and virtual nodes. These nodes and links are dynamic (computed) rather than static (constant). They are defined as expressions in the same language used for queries and are computed at display time. The implementation of different kinds of functions using a common set of mechanisms makes it easy to use them in combination, thus further augmenting the system's functionality.

PHIDIAS supports design by informing architects as they develop a solution's form. The idea is thus not to make the design process faster or cheaper but rather to improve the quality of the things designed. We believe that architects can create better buildings for their users if they have better information. This includes information about buildings of given types, user populations, historical and modern precedents, local site and climate conditions, the urban and natural context and its historical development, as well as local, state and federal regulations.

title Visual Databases as Documentation and On-Line Information Systems
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary After the wide-spread use of computers as task processors, either for algorithmic operations, or for advanced interfaces, the emphasis has shifted on computers as communicators. Beyond basic serial communications, computers serve as providers of information, linking organizations and expanding the bounded rational of professionals. Based on the use of computers as communica-tors, a multiplicity of visual databases for architecture have emerged in the recent years. Building on a maturing technology, those databases address different domains of design, either aiming to provide the designers with information for making informed decisions, or aiming to document prior designs. However, a common characteristic of those visual databases is a separation between the design of the database, versus the entering of the critical amount of data that can make the databases useful. While the research has progressed in the designs, and technological problems of data presentation and data transfer have reached workable solutions, most of the efforts have not succeeded yet in providing the critical mass of information that is required to make the use of the databases desirable. Furthermore, this effort seems as having less research interest, while the necessary amounts of data, and especially the updating of those data, makes the task impossible for academic institutions, and requires interorganizational efforts. This paper focuses on the duality of the databases, either as a form of documentation, or as on-line interactive information systems. Based on that distinction, it examines the required technology and the critical success factors of each type, and proposes that these databases add value to design and they have considerable market effects, which will drive their development and diffusion.

summary Currently, there is a debate among architectural educators regarding the use of computers in the curricula. At present, computers are used for design purposes, and there is limited use in other areas of the curricula. This paper explores an instructional tool developed specifically for the teaching and learning of architectural history and theory, and since these courses are main components of any architectural curricula, using this tool can have a great impact on architectural education in general. The tool, called ArchiWAIS, is a multimedia-based architectural information system that utilizes emerging computer technologies such as multimedia, hypermedia, and telecommunications. As a multimedia system ArchiWAIS provides effective ways of handling various architectural media-text, images, architectural drawings and diagrams, three-dimensional models, animation and sound. ArchiWAIS as a distributed hypermedia system also provides multiple ways to search multimedia databases and browse through multimedia. ArchiWAIS is a WAIS (Wide-Area Information Server) client and has access to architectural databases specially constructed for this experimental project as well as general WAIS databases. ArchiWAIS is one of two subsystems of ArchiTOUR, an educational system currently under development. While ArchiWAIS searches and collects a variety of architectural information, HyperTOUR, the other subsystem of ArchiTOUR, can be used for presenting and learning a specific subject in architectural history and theory. A future extension of ArchiTOUR will be the integration of other curricula into the system, in essence, creating a common ground among architectural courses.

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.

title Architectural Photogrammetry & Knowledge-Base Systems Record & Redevelopment
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary In redevelopment projects, the purpose of heritage recording is part of an investigative process to achieve understanding about structures so that designers can make the appropriate design decisions. It is desirable to integrate the knowledge of the recording and documentation specialist, who has first-hand knowledge of the building, with the interpretative process of evaluating the building information and making design decisions. New developments in the fields of photogram-metric recording and computer science has led to improved "image understanding". This paper describes research that is the result of exploring the concept of integrating new digital photogram-metric recording processes with an automated expert evaluation tool. The goal of this research is to expedite the acquisition of heritage building information for use by a knowledge-based system capable of providing the designer with building performance evaluations. Photogrammetry records all data as a series of three-dimensional coordinates which make it a natural partner for today's three-dimensional CAD systems. Generating a three-dimensional model of architecturally significant physical forms and details can provide a basis for evaluation, understanding, education, and design. The purpose of knowledge-based systems in construction is to enhance the decision-making process with specialized knowledge and experience. The linkage of CAD databases with knowledge-based systems provides a source of input data, such as a three-dimensional model, significant to a particular problem. This research is a collaborative effort between two groups, the Swiss Federal Institute of Technology in Zurich Switzerland, and the University of Manitoba in Winnipeg, Canada.

summary What is the role of CAAD as a tool of architectural form creation ? We used to over-estimate the role of computer as significant factor of design process. In fact it serves only to produce technical documentation and to visualise designed buildings. We usually use CAAD to record ideas, not to create designs. We use it like more complex pencil. But it is unsuitable for conceptual design , with imperceptible influence on idea definition. Its practical usefulnes is limited. I would like to consider and find out reasons of that state, present some conclusions and ideas on computer aided architectural form creation. Many tools were invented to extend posibilities of human body or intellect. Microscop and telescop are extensions of human eye. Which organ is extended by computer (especially by CAAD)? CAAD with high developed function of visualising of the object beeing designed seems to be an extension of architect's imagination. It is beeing used to foresee visual efects, to check designed forms, to see something what we are not able to imagine. It performes the role of electronic modeler. Real model and virtual model - the medium of presentation is diferent but ways of using them are similar . Dislocation of place where we build model is not a big achievement, but potential possbilities of CAAD in modeling are almost unlimited (?). What are special features of CAAD as a modeling tool? First we have to consider what is indispensible when building a model: to embody idea. To do this we need space, substance and tools. In architectural design practice space is a real site with definite climate, neigbourhood, orientation. Substance that we shape is an archiectural form composed of many difrent elements: walls, windows, roof, entry, ... , proportions, rhythm, emotions, impresions... The tool is: our knowledge, imagination, talent, experience, norms, law and drawing equipment. Working with the computer, making virtual model, we have many of mentioned elements given in structure of CAAD program and interpreted by it. But many of them have different character. Making traditional dummy of building we operate on reality which is manually accessible. In case of computer model we operate on information. Space, substance and tool (- program) are informations, data. Human being is not an abstract data processor, but creature that lives non stop in close, direct, sensual contact with nature. By this contact with enviroment collects experiences. Computer can operate on digital data that is optionally selected and given by user, independent upon enviromental conditions. Usually architecture was created on basis of enviroment, climate, gravity. But these do not exist in CAAD programs or exist in the symbolic form. Character of these conditions is not obvious. We can watch demeanour of objects in gravity but it can be also antigravity. In theory of systems everything is considered as a part of biger system. In "virtual" reality (in computer space) we deal with accurences which are reduced to abstract level, free upon terms or connections. We work with our CAAD software using geometric space whithout any other principle.

summary Since 1993, we have experimented with Virtual Design Studios (VDS) as an on-going research project that investigates the combination of current computer-aided design (CAD), computer networks (Internet), and computer supported collaborative work (CSCW) techniques to bring together studentsat geographically distributed locations to work in a virtual atelier. In 1993 the theme of the first joint VDS project was in-fill housing for the traditional Chinese walled village of Kat Hing Wai in the New Territories north of Hong Kong, and our partners included MIT and Harvard in Boston (USA), UBC in Vancouver (Canada), and Washington University in St. Louis (USA). In 1994 we were joined by Cornell (USA) and Escola Tecnica Superior d’Arquitectura de Barcelona (Spain) to re-design Li Long housing in Shanghai, and 1995 added the Warsaw Institute of Technology (Poland) for the ACSA/Dupont competition to design a Center for Cultural and Religious Studies in Japan. The 1996 topic was an international competition to design a monument located in Hong Kong to commemorate the return of Hong Kong to Chinese sovereignty in 1997. Communication was via e-mail, the WorldWide Web with limited attempts at VRML, and network video. Several teaching and research experiments conducted through these projects have demonstrated the viability and potential of using electronic, telecommunications, and videoconferencing technologies in collaborative design processes. Results of these VDS have been presented at conferences worldwide, explained in journal papers and published in Virtual Design Studio, edited by J. Wojtowicz, published by HKU Press.

title Mapping a Single Data Stream to Multiple Auditory Variables: A Subjective Approach to Creating a Compelling Design
source Proceedings of the Third International Conferenceon Auditory Display, Santa FO Institute
summary Representing a single data variable changing in time via sonification, or using that data to control a sound in some way appears to be a simple problem but actually involves a significant degree of subjectivity. This paper is a response to my own focus on specific sonification tasks (Kramer 1990, 1993) (Fitch & Kramer, 1994), on broad theoretical concerns in auditory display (Kramer 1994a, 1994b, 1995), and on the representation of high-dimensional data sets (Kramer 1991a & Kramer & Ellison, 1991b). The design focus of this paper is partly a response to the others who, like myself, have primarily employed single fundamental acoustic variables such as pitch or loudness to represent single data streams. These simple representations have framed three challenges: Behavioral and Cognitive Science-Can sonifications created with complex sounds changing simultaneously in several dimensions facilitate the formation of a stronger internal auditory image, or audiation, than would be produced by simpler sonifications? Human Factors and Applications-Would such a stronger internal image of the data prove to be more useful from the standpoint of conveying information? Technology and Design-How might these richer displays be constructed? This final question serves as a starting point for this paper. After years of cautious sonification research I wanted to explore the creation of more interesting and compelling representations.

title Identification And Analysis of the Recreational Behaviour Forms and the Needed Recreational Space Using the Integrated Spatial and Object-Oriented Gis: Concepts and Statements
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary This paper is concerned with how to measure and investigate changes in the recreational behaviour and the required recreational space in Polish seaside recreational areas in last few years. Spatial information is an integral part of the identification and analysis of recreational behaviour and required recreational space. We postulate, therefore, that spatial information should be fully incorporated in integrated object-oriented GIS and Decision Support Technology. We argue in this paper that the existing theoretical approaches with their descriptive and technical basis do not offer directions for its application and evaluation. They do not seek to explain the processes undergone by spatial information, nor define appropriate data models. New approaches to GIS use object-oriented structures and expert systems concepts, and they will become increasingly helpful in understanding GIS. It is not unreasonable to expect that the most important issue is to use a data model or object-oriented models which closely represent the user's concept of the geographic object for representing spatial phenomena. We have discovered that most Polish users in this field are unable to collect the data they require directly. Thus they have to use methods and techniques, which cannot be found in GIS such as SWOT analysis. According to our experiences, the identification and analysis of the recreational behaviour and the required recreational space should be defined as a system approach where: (i) recreational space requires an object, (ii) state of recreational space is defined by the set of values of recreational space features, and (iii) the utility of the recreational space is defined by a set of features. The identification and analysis of the recreational behaviour in the presented approach are based on the features/utilities matrix of the recreational space and the computer map. The development of such a system needs many organizational changes. It is shown that in many applications organizational rather than the technical aspects of GIS determine their future and open the way to new spatial analytical techniques.
