title	Possibilities and Constraints of using Virtual Reality in Urban Design
source	CORP 2002, Vienna, pp. 457-463
summary	This study aims at exploring the rapid growth of the use of Virtual Reality techniques in the field of Urban Design. Currently, VirtualReality —the ultimate representation— and Virtual Environments are the most growing fields of information technology and have agreat media attention. This research discusses the possibilities and limitations of applying Virtual Reality (VR) technology inenvironmental simulations for urban design practice. There is evidence to suggest that the use of such technology will enhanceconceivable image of any proposed project at any urban setting for users, designers and clients. Therefore, city officials andadministrators (clients) and the public (users) can reach better decisions regarding proposed projects within their towns and cities.Specifically, this research structured in several interdependent parts: the first part is concerned with the definition of VR as well as abackground of its history and current achievements. Types and components of VR systems are described and traditional simulationtechniques are reviewd. In addition, a discussion of current attempts in incorporating VR in urban design disciplines are presented.This discussion raises the question of appropriateness of the VR techniques in urban design projects. An assesment of both potentialsand limitations of aplying this technique, i.e. VRML (Virtual Reality Modelling Language), are discussed. This study definespotentialities, constraints and problems of using this technique, and recommends future research efforts in the field of using theVirtual Reality as a medium for delivering real content for those interested in the design of the built environment.

title	The Quantum Matrix:A Three Dimensional Data Integration and Collaboration ToolFor Virtual Environments
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	If a picture is worth a thousand words, what if they could walk and talk? How would you like to bring a whole new dimension to your ideas; to use visualization to convey a sense of time and motion, to use imagery to give your ideas vividness; to use sound to give them voice and view them threedimensionally. The Matrix allows you to do all of this and much more. The Matrix resembles Rubik’s cube, but its purpose is to store, manage and access data of all types and to view them in three dimensions in virtual environments such as the CAVE and on your desktop. The current version can store, access and view almost anything that is in digital form, including:Text files Pictures Video Clips Sound Files Spreadsheets URL’s HTML pages Databases CAD drawings Gantt Charts Business Graphics VRML modelsExecutable Programs OLE (Object Link & Embedded) The Matrix is a three-dimensional multimedia and document management tool. The Matrix anticipates the convergence of electronic media into one consistent environment for analysis and representation. the Matrix uses VMRL and OpenGL technologies to allow the user to be immersed in their data as withCinerama, IMAX and Virtual Reality Environments. The Matrix allows the user to exercise their creativity by interactively placing and organizing their data three dimensionally and navigating through and viewingdata and documents in 3D (monocular and binocular – stereo). The Matrix user interface is simple to use. Employing the now familiar “drag and drop” method to manage data and documents. Items can be placed into the matrix grid at a user selected matrix cube location. Upon dropping a document on a cube it appears as a mapped image onto the surface. Navigating through the 3D Matrix-space is fun. All navigation uses real-time animation giving you instant feed back as to where you are. Data drilling is as simple as mouse click on a Matrix cube. Double clicking the on an object in the matrix activates that object. Data dreams was an image that preexisted the program by several years. The dream was to create a new way oforganizing and exploring data. The Qube image was created using Microstation by Bentley Systems, Inc. The figure was modeled using Poser by MetaCreations and composited using Adobe Photoshop.

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

source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
summary	Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title	A Study of the Accuracy of Daylighting Simulation of Heavily Obstructed Buildings in the Urban Canyons of Athens
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 456-463
doi	https://doi.org/10.52842/conf.ecaade.2002.456
summary	This paper deals with the use and evaluation of daylighting simulation tools in relation to a complex urban environment. The environment concerned is one commonly found in city centre areas where the proximity of buildings leads to the creation of ‘urban canyons’; the result of this is that assessment and simulation of daylight requires a more sophisticated approach than for other situations. In urban areas building layout is the most important factor effecting daylight, sunlight and solar heat gain reaching a building. It also affects sunlight in open spaces, ventilation, shelter and the dispersal of pollutants. In order to produce a more realistic understanding of the dynamic effects of daylight, there is a need not only for the research and development of advanced CAD and lighting simulation tools, but also of the study of possible alternative methods in their application. In the work reported in this paper, an attempt has been made to move the focus of lighting and daylighting simulation from the scale of a room to that of a whole building; the building itself being surrounded by its specific urban environment (including its microclimate). The study evaluates if there is sufficient evidence that it is possible with such complexity to reach reliable computation results after executing the simulation. The case study presented uses a 4D model of an urban canyon to investigate the sensitivity of such a complex simulation system. It can also be used to find ways to analyse and predict how daylight is reflected, refracted, scattered, diffused, polarised, diffracted and absorbed as it traverses an urban environment.

title	On an alternative framework for building virtual cities: supporting urban contextual modeling on demand
source	Environment and Planning B: Planning and Design, Vol. 29, pp 87-103, Jan 2002
summary	For various purposes, virtual city applications have been developed around the globe to provide users with online resources and services over the Internet. Following our research on the Sheffield Urban Contextual Databank (SUCoD) project, this paper presents an alternative framework for building virtual cities, which goes beyond conventional static urban modelling. A three-tier system framework is described in conjunction with the design and implementation of the SUCoD prototype. We demonstrate SUCoD's novel functionalities by showing that complex urban contextual information sets, including three-dimensional interactive models, multilayer interactive maps, and hypermedia documents, can be retrieved dynamically by user-specified urban contextual attributes, spatial loca- tions, and boundaries. The three-tier framework also facilitates system development in an extensible way, allowing continuous parallel extensions of system functionalities, user-interface components, and contextual data resources. SUCoD's dynamic capabilities are considered crucial in its future uses for urban contextual modelling on demand in relation to the past, present, and future of the City of Sheffield.

title	Making Sense of Presenting Design Ideas through Animated Form
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 560-563
doi	https://doi.org/10.52842/conf.ecaade.2002.560
summary	This paper describes both conventional and computational ways of expressing and exploring design concepts with the use of models. We explain the role and function of the model in the design process, and investigate the ways in which models become reflections and representations of architects’ design thinking. We compare and contrast the physical properties of conventional models with those of three-dimensional computer models, and the corresponding processes of model creation, model development, and model modification. The paper includes a brief overview of commonly used forms of computer representations often encountered in Computer Aided Design applications. Whatever the visual richness of computer models in virtual environments can be, we believe that, just as in the use of conventional two-dimensional architectural drawings, computational presentations of architectural design concepts have their own conventions of use. This paper addresses the need to more accurately understand these conventions of using computer models for the representation of architectural design concepts. Therefore, we will illustrate the more dynamic qualities of computer models, which have the potential to allow designers to escape from the restrictions and constraints of physical form. In particular, we demonstrate these qualities in the context of architectural presentations in the medium of computer animation. These new forms of expression of design thoughts and ideas go beyond mere model making, and move more towards scenemaking and storytelling. The latter represents new methods of expression within computational environments for architects and designers.

title	Exploring syntax and semantics of spatial structure - A study on Traditional Taiwanese City form in Chi’i’ng Dynasty
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 412-416
doi	https://doi.org/10.52842/conf.ecaade.2002.412
summary	Abstract. In this paper, we want to figure out the relations of complex semantics and syntax on five traditional Taiwanese cities in Chi’i’ng Dynasty by using a language approach. The issues of traditional Taiwanese central city in Chi’ing Dynasty had been interpreting by historical, social, and cultural research but had lacked the explicit construction of spatial structure on semantics-syntax. Therefore, we use a data modeling on knowledge level to describe the relationship between syntax and semantics. Through the research of Chi’ing Dynasty‘s history, we find out the spatial relations of Taiwanese traditional city to establish the functional categories of spatial structures. Then the language of semantics components and the meaning’s attributes are coded as logical statements to map the elements of syntax on architectural form, political vocabularies, spatial layout, and spatial myth. We argue that using this approach several social and spatial structures of cities can be clearly defined and understood.

title	Physical and Digital Media Strategies For Exploring ‘Imagined’ Realities of Space, Skin and Light
source	Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 13-23
doi	https://doi.org/10.52842/conf.acadia.2002.013
summary	This paper will discuss an unconventional methodology for using physical and digital media strategies ina tightly structured framework for the integration of Environmental Control Systems (ECS) principles intoa third year design studio. An interchangeable use of digital media and physical material enabledarchitectural explorations of rich tactile and luminous engagement.The principles that provide the foundation for integrative strategies between a design studio and buildingtechnology course spring from the Bauhaus tradition where a systematic approach to craftsmanship andvisual perception is emphasized. Focusing particularly on color, light, texture and materials, Josef Albersexplored the assemblage of found objects, transforming these materials into unexpected dynamiccompositions. Moholy-Nagy developed a technique called the photogram or camera-less photograph torecord the temporal movements of light. Wassily Kandinsky developed a method of analytical drawingthat breaks a still life composition into diagrammatic forces to express tension and geometry. Theseschematic diagrams provide a method for students to examine and analyze the implications of elementplacements in space (Bermudez, Neiman 1997). Gyorgy Kepes's Language of Vision provides a primerfor learning basic design principles. Kepes argued that the perception of a visual image needs aprocess of organization. According to Kepes, the experience of an image is "a creative act ofintegration". All of these principles provide the framework for the studio investigation.The quarter started with a series of intense short workshops that used an interchangeable use of digitaland physical media to focus on ECS topics such as day lighting, electric lighting, and skin vocabulary tolead students to consider these components as part of their form-making inspiration.In integrating ECS components with the design studio, an nine-step methodology was established toprovide students with a compelling and tangible framework for design:Examples of student work will be presented for the two times this course was offered (2001/02) to showhow exercises were linked to allow for a clear design progression.

title	Road hierarchy and speed limits in Brasília/Brazil
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

summary	Although virtual reality (VR) is a fast-growing field, utilization of its potential within an affordable environment in the early years of architectural education has been limited. Currently, we are in the process of exploring the educational potential of virtual reality in the creation and understanding of space as a set of dynamic volumes that can be experienced. The VR-Desktop initiative is an effort to bring the salient features of projection-based VR to second-year architecture students in a way that is more generally accessible than the many canonical, first-generation, projection-based VR systems. The VR-Desktop has been implemented in the teaching of the architectural design studio in the second year of a fiveyear curriculum, as part of the physical architectural studio. Through the VR-Desktop system in the studio, students immediately start working in an immersive environment. They create space by manipulating solids and voids while evaluating the anthropometric relations of the proposed solution. The students are able to study and test conceptual details in a virtual environment from the very beginning of their architectural design project. In order to assess student perception of the usefulness of various system attributes for diverse tasks, we have begun a usability study. Thirty-five surveys were collected from the students who had used the lab during the two semesters for which the two-screen system was available. Preliminary observations indicate that within the architectural context, virtual reality techniques involving depth perception can convey relevant information to students more efficiently and with less misrepresentation than traditional techniques. This paper suggests that full field of view, motion, stereoscopic vision, and interactivity are possible components of the 3D visualization techniques that are necessary to enhance architectural education

doi	https://doi.org/10.52842/conf.acadia.2002.229
summary	In this paper, we present two user-centered systems aiming at making easier the modeling ofarchitectural and urban scenes by using two different but complementary approaches. The first oneMArINa, an image-based modeler, allows the user to reconstruct urban scenes from one or moregraphical documents. This method focuses more on reconstructing models and is more dedicated tothe production of 3D sketches. The second modeler, MArCo is a knowledge-based modelercontaining the know-from and know-how on classical architecture. It allows the user to modelclassical architectural scenes verifying automatically all the domain rules. Finally, we show howMArINa and MArCo can cooperate providing the user a tool combining efficiently their respectivecapabilities.

summary	The existing CAD and CAAD programs and design applications hardly support the urbanistic designactivities. Although those applications are useful means to be utilized generally in design tasks, they arenot suitable tools as urbanism community needs. Most existing CAD programs are based on thearchitectural design process and therefore not suitable for urbanistic design. The conceptual differencebetween architecture and urbanism necessitates developing new CAD software based on the urbanisticdesign process. We believe that our developed Urban-CAD system assists designers with urbanisticdesign activities and overcomes the limitations of the already existing CAD applications.

summary	Today the development of network-based virtual communities and the use of avatars have brought a new level of complexity to the meaning of virtuality, providing the technology for remote presence and collaborative experiences. In this project the intention was to pursue this articulated vision of VR in order to assist the design profession during the early stages of the design process. The objective was to provide a tool that is capable of creating 3D shapes in a shared VR environment, thus allowing thedesign and its evolution to be shared. The use of the Java programming language was a natural choice for this project. Because of Java’s performance scalability and hardware independence the concept ofCAAD has been extended, making it possible to create a VR environment that can co-exist between high-end supercomputers and standard PCs. The project is currently being tested using PCs and an SGI system running a Reality Centre. The research reported in this paper describes the architecture and application of software that aims to increase the opportunity for collaboration within virtual worlds and enable effective and transparent information exchange.

title	Integration System of Archaeological and Geographical Informationfor Planning in Historical Regions
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary	This study aims to construct the GIS for supporting the planning process and archaeological analysis in the historical regions by integrating geographical data and archaeological data on the sites with ruinsand remains in various period from ancient through medieval which had been buried and was recently excavated in geologic layers and mounds. First, for understanding the trends of environmental condition the excavated sites, we analyze the relationship between the site location and the condition ofgeography and natural environment by using the constructed system.Secondary, we develop the system to make it possible to browse and operate the information on the GIS through the internet. This web GIS constructed by us supports sharing the information on planning for preservation of historical sites among city planners, archaeologists and citizens, and serve as a tool for the collaboration and the coordination of urban development and historical preservation. Finally, as the application with the GIS, we show the results of case studies and point out the merits and effects about usage of the GIS for archaeological analysis as well as learning the local history.

title	Perception Aspects in Underground Spaces using Intelligent Knowledge Modeling
source	Delft University of Technology
summary	The intensification, combination and transformation are main strategies for future spatial development of the Netherlands, which are stated in the Fifth Bill regarding Spatial Planning. These strategies indicate that in the future, space should be utilized in a more compact and more efficient way requiring, at the same time, re-evaluation of the existing built environment and finding ways to improve it. In this context, the concept of multiple space usage is accentuated, which would focus on intensive 4-dimensional spatial exploration. The underground space is acknowledged as an important part of multiple space usage. In the document 'Spatial Exploration 2000', the underground space is recognized by policy makers as an important new 'frontier' that could provide significant contribution to future spatial requirements.In a relatively short period, the underground space became an important research area. Although among specialists there is appreciation of what underground space could provide for densely populated urban areas, there are still reserved feelings by the public, which mostly relate to the poor quality of these spaces. Many realized underground projects, namely subways, resulted in poor user satisfaction. Today, there is still a significant knowledge gap related to perception of underground space. There is also a lack of detailed documentation on actual applications of the theories, followed by research results and applied techniques. This is the case in different areas of architectural design, but for underground spaces perhaps most evident due to their infancv role in general architectural practice. In order to create better designs, diverse aspects, which are very often of qualitative nature, should be considered in perspective with the final goal to improve quality and image of underground space. In the architectural design process, one has to establish certain relations among design information in advance, to make design backed by sound rationale. The main difficulty at this point is that such relationships may not be determined due to various reasons. One example may be the vagueness of the architectural design data due to linguistic qualities in them. Another, may be vaguely defined design qualities. In this work, the problem was not only the initial fuzziness of the information but also the desired relevancy determination among all pieces of information given. Presently, to determine the existence of such relevancy is more or less a matter of architectural subjective judgement rather than systematic, non-subjective decision-making based on an existing design. This implies that the invocation of certain tools dealing with fuzzy information is essential for enhanced design decisions. Efficient methods and tools to deal with qualitative, soft data are scarce, especially in the architectural domain. Traditionally well established methods, such as statistical analysis, have been used mainly for data analysis focused on similar types to the present research. These methods mainly fall into a category of pattern recognition. Statistical regression methods are the most common approaches towards this goal. One essential drawback of this method is the inability of dealing efficiently with non-linear data. With statistical analysis, the linear relationships are established by regression analysis where dealing with non-linearity is mostly evaded. Concerning the presence of multi-dimensional data sets, it is evident that the assumption of linear relationships among all pieces of information would be a gross approximation, which one has no basis to assume. A starting point in this research was that there maybe both linearity and non-linearity present in the data and therefore the appropriate methods should be used in order to deal with that non-linearity. Therefore, some other commensurate methods were adopted for knowledge modeling. In that respect, soft computing techniques proved to match the quality of the multi-dimensional data-set subject to analysis, which is deemed to be 'soft'. There is yet another reason why soft-computing techniques were applied, which is related to the automation of knowledge modeling. In this respect, traditional models such as Decision Support Systems and Expert Systems have drawbacks. One important drawback is that the development of these systems is a time-consuming process. The programming part, in which various deliberations are required to form a consistent if-then rule knowledge based system, is also a time-consuming activity. For these reasons, the methods and tools from other disciplines, which also deal with soft data, should be integrated into architectural design. With fuzzy logic, the imprecision of data can be dealt with in a similar way to how humans do it. Artificial neural networks are deemed to some extent to model the human brain, and simulate its functions in the form of parallel information processing. They are considered important components of Artificial Intelligence (Al). With neural networks, it is possible to learn from examples, or more precisely to learn from input-output data samples. The combination of the neural and fuzzy approach proved to be a powerful combination for dealing with qualitative data. The problem of automated knowledge modeling is efficiently solved by employment of machine learning techniques. Here, the expertise of prof. dr. Ozer Ciftcioglu in the field of soft computing was crucial for tool development. By combining knowledge from two different disciplines a unique tool could be developed that would enable intelligent modeling of soft data needed for support of the building design process. In this respect, this research is a starting point in that direction. It is multidisciplinary and on the cutting edge between the field of Architecture and the field of Artificial Intelligence. From the architectural viewpoint, the perception of space is considered through relationship between a human being and a built environment. Techniques from the field of Artificial Intelligence are employed to model that relationship. Such an efficient combination of two disciplines makes it possible to extend our knowledge boundaries in the field of architecture and improve design quality. With additional techniques, meta know/edge, or in other words "knowledge about knowledge", can be created. Such techniques involve sensitivity analysis, which determines the amount of dependency of the output of a model (comfort and public safety) on the information fed into the model (input). Another technique is functional relationship modeling between aspects, which is derivation of dependency of a design parameter as a function of user's perceptions. With this technique, it is possible to determine functional relationships between dependent and independent variables. This thesis is a contribution to better understanding of users' perception of underground space, through the prism of public safety and comfort, which was achieved by means of intelligent knowledge modeling. In this respect, this thesis demonstrated an application of ICT (Information and Communication Technology) as a partner in the building design process by employing advanced modeling techniques. The method explained throughout this work is very generic and is possible to apply to not only different areas of architectural design, but also to other domains that involve qualitative data.

title	Interactive Tools for Collaborative Architectural Design
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	Today’s rapidly changing society is continuously developing towards an increased demand for multistakeholder knowledge and influence in the architectural planning and design process. Accordingly, we are working with developing and setting up a partner engaged collaborative design process. It includes active collaboration between users, external partners and designers, and visualizations in conceptual design and scenario building. My research is focusing on integrating visualization technology in theseprocesses by application of digital tools. We have developed a working prototype for an interactive design tool. The prototype is an extremely “easy to use” digital modeling tool called “ForeSite Designer.” With this tool one builds one’s own spatial environment with elements on a 2D surface.With one command the 2D layout is exported to a lit-up 3D/Virtual Reality world in the computer game “Half-Life”. ForeSite Designer has lately been used in a series of workshops together with external users. In these processes ForeSite Designer has played a crucial role as an arena of building spatially arranged concepts of future environments. The results show that it works, and, importantly, promotes a collaborative engagement among the users.
