title	The architectural aspect of designing space in virtual environments
source	University of Strathclyde, Dept. of Architecure and Building Science
summary	This thesis deals with the architectural aspect of virtual environment design. It aims at proposing a framework, which could inform the design of three-dimensional content for defining space in virtual environments, in order to aid navigation and wayfinding. The use of such a framework in the design of certain virtual environments is considered necessary for imposing a certain form and structure to our spatial experience in there. Firstly, this thesis looks into literature from the fields of architectural and urban design theory, philosophy, environmental cognition, perceptual psychology and geography for the purpose of identifying a taxonomy of spatial elements and their structure in the real world, on the basis of the way that humans think about and remember real environments. Consequently, the taxonomy, proposed for space in the real world is adapted to the intrinsic characteristics of space in virtual environments, on the basis of human factors aspects of virtual reality technology. As a result, the thesis proposes a hypothetical framework consisting of a taxonomy of spatial and space-establishing elements that a virtual environment may comprise and of the possible structure of these elements. Following this framework, several pilot virtual environments are designed, for the purpose of identifying key design issues for evaluation. As it was impossible to evaluate the whole framework, six specific design issues, which have important implications for the design of space in virtual environments, are investigated by experimental methods of research. Apart from providing answers to these specific design issues, the experimental phase leads to a better understanding of the nature of space in virtual environments and to several hypotheses for future empirical research.

summary	In the field of architectural and urban planning and design, computer education needs to move beyond basic computer literacy and have more emphasis placed on special subjects related to planning and design. How to manage spatial data is becoming an essential issue for research and education in planning and design especially in the analysis and evaluation phases. This paper discusses the importance of spatial data in planning education and shows how a common spatial database for model analysis methods was constructed at the University of Tsukuba. The database consists of many geographical and statistical data files classified under the standard region mesh codes and covers the whole country from global areas to local areas. Web-based instructions about how to use the database have also been prepared which enable students to study practical spatial analysis by themselves.

title	Ouvoir - Of the Potential Architecture

summary	Calculations are used to forecast urban flows of population, development of various activities, demography, and many other architectural programme constrains, and have been spontaneously the first field of computer intervention in urban and architectural project design. By analogy to engineering where computation is the base of decision making, architectural design process is seen as a problem solving process. <> constrains computer aided computation is seen as Computer Aided Architectural Design, CAAD. This way, a technological utopia called CAD in architecture is born. Nevertheless, the review of architectural design methods has clearly shown that programmatic models, since they are only used to evaluate spatial hypothesis, and do not have in themselves space production potentialities. In spite of the powerful methodological movement of the sixties, that have established this design constellation, the misunderstanding persists until now. Architect is a gestural and visual being. By using simultaneously metaphor, gesture and calculation, he calls for all his experiences and sensibility to realise plastic and poetic synthesis of form. To remedy to the major problem of the form synthesis, graphical instruments have been proposed. Why not utilise tools used in the field of engineering as computer aided drafting ? And so, computer aided drafting triumphaly entered the architectural design process. But, computer aided drafting is commonly seen as an instrument used on the - projection - stage, where drawings are produced for an already designed object. A new myth that assimilate architectural design to the drawing production activity arrives with the <>, containing thousands of drawings. All this aimed to facilitate, as it is proclaimed, communication between all the intervening in the project.

title	Prototypical Laboratory Design to Support Learning and Teaching
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	Collaboration between designers and scientists is an unusual combination to undertake the prototypical design of a teaching laboratory funded by Howard Hughes Medical Institute. The zoologists are developing a cooperative learning and interactive teaching pedagogy to make learningscience a process of critical inquiry and discovery. The industrial and interior designers are paying attention to the design issues of function and environmental support for teaching and doing the work required in a three-hour, hands-on beginning science learning space. Using both qualitative andquantitative research methods, the designers are able to determine a framework for making design decisions in prototypical beginning science environments. This framework is being developed as a guideline for designing similar environments at other institutions of higher learning. Videotape analysis precedes the research to uncover the underlying problems of the existing space and to formulate the questions for the research. Elements of a case study and an evaluative study integratewith the design process to form the basis of an intensive investigation of design issues for a beginning science teaching laboratory. Using two pretests as a baseline, the posttest data evaluates the success orfailure of the prototypical design. Both the pretests and the posttest evaluate the physical attributes of the old and new learning environment related to a beginning laboratory course in Zoology at Arizona State University.

title	Data Visualization Methods for the Blind using Force Feedback and Sonification
source	Stein, M. (Ed.). Telemanipulator and Telepresence Technologies V. Vol. 3524
summary	Research in the field of scientific visualization has begun to articulate systematic methods for mapping data to a perceivable form. Most work in this area has focused on the visual sense. For blind people in particular, systematic visualization methods which utilize other sense need further development. In this work we develop methods for adding aural feedback to an existing haptic force feedback interface to create a multimodal visualization system. We examine some fundamental components of a visualization system which include the following: characterization of the data, definition of user directives and interpretation aims, cataloging of sensual representations of information, and finally, matching the data and user interpretation aims with the appropriate sensual representations. We focus on the last two components as they relate to the aural and haptic sensor. Cataloging of sensual representations is drawn form current research in sonification and haptics. The matching procedure can be thought of as a type of encoding which should be the inverse of the decoding mechanism of our aural and haptic systems. Topics in human perception are discussed, and issues related to the interaction between the two sensor are addressed. We have implemented a visualization system in the from of a Windows NT application using a sound card and a 3 DOF point interaction haptic interface. The system present a 2D data set primarily as a polygonal haptic surface although other capabilities of the haptic sensor are utilized such as texture discernment. In addition, real time aural feedback is presented as the user explores the surface. Parameters of sound such as pitch and spectral content are used to convey information. Evaluation of the system's effectiveness as an assistive technology for the blind reveals that combining aural and haptic feedback improves visualization over using either of the two senses alone.

title	Integrated Land-Use and Network Modelling
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	In this paper, the integration of modelling the changes in land-use and the changes in the infrastructure network will be described. Emphasis is laid on the automatic development of the network instead of changing the network by hand before simulating the changes in the land-use pattern.The approach and working procedure were tested by developing a pilot model simulating the spatial situation on the Frisian island Ameland (The Netherlands). The pilot is developed within the geographical information system Arcinfo. In this pilot model, special attention is paid to the extension of the infrastructure network and the allocation of more than one activity. Network analysis for the purpose of network extension is based on graph theory. Selection of links is based on the increase of the total accessibility within the network system as a result of adding a link to the network. The allocation of activities is based on several selection criteria and takes place within a cellular grid. Several methods ofselecting cells and links and the choices made will be discussed.

summary	Auditorium design is a complex task. Various programmatic, functional and acoustical parameters have to be resolved in the spatial design of an auditorium. This ongoing research project deals with the development of a computer-aided design system for the preliminary spatial design of proscenium type auditoriums. The concept of “acoustic sculpting” is used to generate the spatial form of the auditorium from programmatic, functional and acoustical parameters. These parameters are incorporated using a combination of mathematical, empirical and statistical methods. The generation of the spatial form of the auditorium is implemented as an algorithm that is executed on the computer. The spatial form of the auditorium generated by the system is exported as a computer model for design development and acoustical analysis.

title	Once More on the Role of Different Methods and Means of the Analysis
source	Cyber-Real Design [Conference Proceedings / ISBN 83-905377-2-9] Bialystock (Poland), 23-25 April 1998, pp. 127-140
summary	The correct evaluation of design proposals both by experts and future users, demands their presentation with regard to the real environment and real conditions of observation. It is interesting when analysing designs in complicated town planning situations, and becomes especially important in CIVILIZED SOCIETIES, when it concerns historic territories. Analytical works, connected with preparation of the information, corresponding in the greatest degree to the real conditions and previous scientific investigations, are carried out in a number of European educational institutions (Technical universities in Delft, Tampere, Stuttgart, etc.), corresponding to the Laboratory of videosystems of the Moscow Architectural Institute (State Academy). Their results are periodically reported at conferences of the European Architectural Endoscopy Association, which in keeping with its name and status is occupied with problems of the most real reflection of the designed space. I suppose that due to the objective necessity at our future conference (the 4th conference of the EAEA) we shall discuss not tools, but methods and ways ensuring correct vision of the designed space. Because of this and the present state of the technique of presentation and also recollecting my words at the previous conferences, that technical means are only tools but not an ideology of the creative activities in designing, it is reasonable once more (or maybe not once) to return to the "accompanying" means, which sometimes, and in a historical environment, i want to underline again, in a CIVILIZED SOCIETY, can and must become decisive. And it is especially important for the simulation means to take into consideration spatial and temporal factors.

summary	Throughout these pages are made known the persons, the projects and the books that have influenced my actions and that they will be mentioned in form underlined in this paper. I have to emphasize that since 1965 to 1970, and in the continuous search that I was accomplishing to find data and bibliography adapted to the topic of computer graphics, only two series of publications contained topics related to this matter at that time: one was the IBM Journal and the other series was the communications of the ACM. The purpose of this work is to make known an experience accomplished throughout 30 years of intense activity in finding new methods of drawing and design, based on the use of digital computers, mainly in Argentina, and during certain periods of time in Great Britain and since 1971 during short visits to the United States and also in France. The first idea emerged in the year 1965 when I was assistant teacher at the School of Architecture of the University of Buenos Aires, as a combination of ideas between the concepts of spatial geometry and the current morphological studies that we taught in the Course of professor Gaston Breyer. However the idea of automatic drawing emerged observing the operation of the first scientific digital computer installed in the Computing Institute of the Faculty of Sciences of the University of Buenos Aires in 1963 (Sadosky 1963). At the beginning, the approach to the computer were not accomplished from a strictly scientific point of view, but it was implying a kind of "sincresis" (Koheler 1940) it is more than a synthesis, because I was tried to combine ideas that have had its origin in different worlds of thinking, the analogous world and the digital world, and this situation was very difficult to accept at that time.The designing procedures in the decade 1960's was deeply rooted (and still continues) in the architectural design field as a result of a drawing process based in heuristic techniques.

title	Indecision in quest of design
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	Designers all start with a solution (Darke, 1984), with what is known (Rittel, 1969, 1970). Hans Menghol, Svein Gusrud and Peter Opvik did so with the chair in the 1970s. Not content with the knowledge of the chair, however, they walked backward to the ignorance of the question that has always elicited the solution of chair and asked themselves the improbable question, “What is a chair?” Their answer was the Balans chair. “Until the introduction of the Norwegian Balans (balance) chair, the multi-billion dollar international chair industry had been surprisingly homogeneous. This chair is the most radical of the twentieth century and probably since the invention of the chair-throne itself (Cranz 1998). Design theorists have tried to understand in a measurable way what is not measurable: the way that designers think. Rather than attempt to analyze something that cannot be taken apart, I attempt to illuminate methods for generating new knowledge through ways of seeing connections that are not logical, and in fact are sometimes ironic. Among the possibilities discussed in this dialogue are the methodological power of language in the form of metaphor, the power of the imagination in mind experiments, the power of mythological story telling, and the power of immeasurable intangibles in the generation of the new knowledge needed to design.

title	Visual Communication in Urban Planning and Urban Design
source	Working Paper 2; Centre for Advanced Spatial Analysis Working Papers; London; June 1998
summary	This Case Study documents the current status of visual communication in urban design and planning. Visual communication is examined through discussion of standalone and network media, specifically concentrating on visualisation on the World Wide Web (WWW). First, we examine the use of Solid and Geometric Modelling for visualising urban planning and urban design. This report documents and compares examples of the use of Virtual Reality Modelling Language (VRML) and proprietary WWW based Virtual Reality modelling software. Examples include the modelling of Bath and Glasgow using both VRML 1.0 and 2.0. The use of Virtual Worlds and their role in visualising urban form within multi-user environments is reviewed. The use of Virtual Worlds is developed into a study of the possibilities and limitations of Virtual Internet Design Arena's (ViDA's), an initiative undertaken at the Centre for Advanced Spatial Analysis, University College London. The use of Virtual Worlds and their development towards ViDA's is seen as one of the most important developments in visual communication for urban planning and urban design since the development plan. Secondly, the role of photorealistic media in the process of communicating plans is examined. The process of creating photorealistic media is documented, and examples of the Virtual Streetscape and Wired Whitehall Virtual Urban Interface System are provided. The conclusion is that, although the use of photo-realistic media on the WWW provides a way to visually communicate planning information, its use is limited. The merging of photorealistic media and solid geometric modelling in the creation of Augmented Reality is reviewed. Augmented Reality is seen to provide an important step forward in the ability quickly and easily to visualise urban planning and urban design information. Third, the role of visual communication of planning data through GIS is examined in terms of desktop, three dimensional, and Internet based GIS. The evolution to Internet GIS is seen as a critical component in the development of virtual cities that will allow urban planners and urban designers to visualise and model the complexity of the built environment in networked virtual reality. Finally, a viewpoint is put forward of the Virtual City, linking Internet GIS with photorealistic multi-user Virtual Worlds. At present there are constraints on how far virtual cities can be developed, but a view is provided on how these networked virtual worlds are developing to aid visual communication in urban planning and urban design.

source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The evaluation of environmental aspects in architectural design has traditionally been performed by means of simple (and often simplistic) rule systems. These generally remain at the normative level of minimal control one encounters in building rules and regulations, thereby failing to provide sufficient information and clarity for design guidance. Despite this, evaluation results normally bound subsequent design decisions as fundamental, inflexible constraints. At much later design stages, whenarchitectural form has been largely crystallized and when environmental subsystems must be specified in detail, both the architect and the contributing engineers often realize the severe limitation of theinitial choices. A frequently voiced argument for such simplification in the guise of abstraction is the lack of detailed information on the form and functional content of a building in the early stages of the designprocess. This obviously presupposes a tabula rasa generative approach. The application of a priori knowledge in the form of types, cases, precedents and automated recognition permits direct transaction from the abstract to the specific at and between a number of predefined relevant abstraction levels in the representation. The combination of a priori knowledge at the typological level with multilevel representations permits the use of precise simulation techniques already in the early design stages and throughout thedesign process. The simulation results employ the dual representation principle of scientific visualization, thereby linking form with measurable performance. Feedback from the simulation provides the analysis and evaluation means for design guidance and for communication between thearchitect and the contributing engineers. A prerequisite to this is that the abstraction level in the representation constrains the analysis derived from the simulation, e.g., by means of grades of fuzziness applied to different zones in the representation on the basis of information specificity.

summary	The extraordinary characteristic of the city which thrills both its citizens and those who visit it, is the complex way in which multitudes of individual buildings, themselves each a complex of individual spaces, combine to form the weft and weave of the urban fabric. No two cities are alike but each and every one has its innate and endearing character: the grandeur of Vienna, the eternity of Rome, the simplicity of Tucson, the elegance of Edinburgh, the dynamic of Tokyo, the vibrancy of Hong Kong. This presentation illustrates how the emerging computer-based technologies can, in a manner hitherto impossible, explain to students of architecture and urban design (and to the public at large) how the design of individual buildings and their spatial relationship to each other, aggregate to create the environment which characterises the city; in a complementary way it demonstrates how the virtual urban voyager can not only identify and visit individual buildings, but enquire within - to observe, understand and even handle the contents.

source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The proliferation of the computer in the documentation of architectural designs generates a growing number of computerized architectural drawings. As a result, practice is showing an increasing interest in the utility of such drawings. This interest is linked to a fundamental promise of computerization in architecture, the analysis and evaluation of a building’s behaviour and performance during the design process. The main drawback of conventional computerized drawings is that they are restricted toplotting orthographic or, less frequently, perspective projections. This effectively reduces the computer to a mere electronic drafting table and computerized drawings to unstructured, haphazard collectionsof arbitrarily chosen graphic elements, normally of the lowest possible complexity. The lack of structure and in particular of meaningful, relevant primitives leads to inadequate support even for basic analyses and evaluations. We consider the structure of computerized design representations with respect to the choice of primitives that facilitate automation of analysis and support focused feedback. We argue that current drawing systems are capable of deriving the basic dual network of ‘solid’ building elements and ‘void’ spaces on the basis of user-input descriptions of familiar entities and that this network is sufficient for normative analyses.

source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	Location is often considered as the most important factor leading to the success of public or private services. Location is the key in maximising accessibility and keeping operating cost low. A collaborative research project between ‘Nottingham University’ and the ‘Environmental ServicesDepartment of Nottingham City Council’ is developing an ‘Intelligent Map’ for identifying optimum locations for the recycling centres in the city. The object is to develop a new decision support system for urban planners, to be used as a management and analytical tool for improving locational decisionmaking. This paper discusses the technique of the Intelligent Map, and its concept. The paper includes three main sections. The first discusses the introduction of the mini-recycling centres in Nottingham, theproblems associated with their spatial distribution, and the need for a new decision support system using GIS technology. The second examines traditional techniques using GIS for identifying optimum locations and calculating catchment areas. The third explains the concept of the Intelligent Map; discussion takes the form of an initial analysis of the likely method to be applied, and then briefly outlines some of the prototyping work that is currently taking place at Nottingham.

doi	https://doi.org/10.52842/conf.caadria.1998.133
summary	This paper presents the development process and preliminary results of several research projects that apply computational fluid dynamics (CFD) to architectural design. The CFD On-line Teaching project is developing a multimedia training course for architecture students to apply CFD simulation to their projects. Each lesson illus-trates basic principles regarding air flow in building design, and provides CFD sample files with pre-defined flow cells for students to test these concepts. The Chinese Temple project uses CFD simulation to study the wind resistance of a Tong Dynasty heavy timber structure, with particular attention to the roof form. Air flow information generated in the project includes the visual representation of the pressure distribution and velocity field on all slices through the temple, as well as particle tracks around and through the building. The Urban Housing Air Duct project focuses on air duct design for the China Experimental Urban Housing Scheme. The visual representation of the pressure distribution and velocity field in the ducts provides vital information for helping the China Housing Research Center improve the current design.

summary	Compactness of a district or zone is determined by considering its appearance and the area of dispersal of the district (Altman, 1998) and it is used as a characteristic to describe shape (Shiode, 1998; Knight, 1997). However, existing compactness measurement used to assess district plans in redistricting applications are vague and imprecision although there are more than thirty over Euclidean or non-Euclidean measurement methods. Therefore, this paper presents an integrated shape compactness measurement indexing with a fuzzy multicriteria decision making approach (FMCDM) to enhance the measurement of shape compactness. An experiment is conducted in order to verify the practically of the proposed model to improve existing compactness measurement method.

title	From Inversive Perspective to Virtual Space
source	Cyber-Real Design [Conference Proceedings / ISBN 83-905377-2-9] Bialystock (Poland), 23-25 April 1998, pp. 43-52
summary	Looking back at history, considering the proportions taken up by the particular developments of the future vision of an architectural work, one observes that the main method used was based on a form of drawing in the perpendicular projection in the form of "planes", cross sections and elevations. However, the research considering the threedimensional approach of the design solution, took into consideration a model made of wood, plaster or paper. The supplementary works in the form of an axonometric or a perspective drawing were not usually the domain of architects. Such way of presenting space was used by artists: painters and sculptors. The rapid development taking place in the use of computers in preparing architectural design documentation makes one reflect on many issues. Modern software, apart from making it possible to develop projections, cross sections and elevations, allows the presentation of a three dimensional vision of an architectural solution on the basis of axonometry, perspective and a study of virtual space. Despite the obvious progress facilitating the graphic editing process of design work, the initial design phase is an unchanged process, similar to past times ' It is based on transferring the creative invention onto paper by means of handmade sketches, similarly to making an inventory measurement note.

summary	Investment decisions about privately-owned houses are usually based on limited investment budget and vague information about choice alternatives available. Since a household buying a dwelling has to compare the housing expenditure with other expenditures, the financial consequences of the housing investment should be transformed on an annual basis. Furthermore, to be able to make a choice out of various choice alternatives within the annual housing budget, the annual costs of the most importantattributes have to be calculated separately. Cost information about the choice alternatives should be used in combination with their utility in order to be able to allocate the household’s budget. The cost information is objective while utility depends on an individual household. As a consequence, the household should determine its own utility scale. This is accomplished by defining a willingness to pay amount for each choice alternative using a bidding game. The willingness to pay amount reveals the maximum additional amount of money the household is willing to pay for an additional quantity orquality of a certain attribute. In order to maximise the total utility within the budget, the ratios of marginal utility to marginal cost for the attributes have to be compared. The definition of subjective utilities as willingness to pay amounts has drawbacks. Future research should improve the system as concerns utility measurement for the decision support of individual households.
