title	Virtual Reality: Technology of the Future or Playground of the Cyberpunk?

summary	Jaron Lanier is a major spokesperson of our society's hottest new technology: VR or virtual reality. He expressed his faith in the VR movement in this quote which appears in The User's Guide to the New Edge published by Mondo 2000. In its most technical sense, VR has attracted the attention of politicians in Washington who wonder if yet another technology developed in the United States will find its application across the globe in Asia. In its most human element, an entire "cyberpunk movement" has appealed to young minds everywhere as a seemingly safe form of hallucination. As architecture students, educators, and practitioners around the world are becoming attracted to the possibilities of VR technology as an extension of 3D modeling, visualization, and animation, it is appropriate to consider an overview of virtual reality. In virtual reality a user encounters a computersimulated environment through the use of a physical interface. The user can interact with the environment to the point of becoming a part of the experience, and the experience becomes reality. Natural and instinctive body movements are translated by the interface into computer commands. The quest for perfection in this human-computer relationship seems to be the essence of virtual reality technology. To begin to capture the essence of virtual reality without first-hand experience, it is helpful to understand two important terms: presence and immersion. The sense of presence can be defined as the degree to which the user feels a part of the actual environment. The more reality the experience provides, the more presence it has. Immersion can be defined as the degree of other simulation a virtual reality interface provides for the viewer. A highly immersive system might provide more than just visual stimuli; for example, it may additionally provide simulated sound and motion, and simultaneously prevent distractions from being present.

title	Episode as a Unit of Analysis of Movement

summary	Everybody who has read his Gordon Cullen or his Edmund H. Bacon knows that movement has long been recognized as a factor in environmental planning in many ways. For example, in the traditional Japanese promenade garden the importance of movement has always been appreciated. The promenader gains an intense experience of the succession, variation and rhythm of the surrounding scene. The spaces and paths lead him from one stage to another. The spatial structure of the Japanese promenade garden, as well as of traditional Japanese architecture in general, is joined most intensively to time and motion. The environment is in relation to the flow of change in many sense, both concretely and existentially. Taking an example of western urban environment. Here perhaps the most marked sequential spaces are to be found in small medieval, mediterranean towns. Thanks to their organic growth, narrow and winding streets and the emphasis on public squares, most of them provide exciting experiences if the observer is only interested in seeing the townscape from the point of view of movement. There are also examples of this kind of environment in Finland. In old wooden towns like Porvoo and Rauma one can still find varied and rhythmic streetscapes and networks of streets and squares, together with a human scale and an almost timeless atmosphere. One could say that such an opportunity to experience spaces sequentially, or as serial visions, is an important dimension for us, especially as pedestrians. And as Gordon Cullen has shown there is in any urban environment much scope to heighten this experience. For example, by creating a sense of ’entering in’ some place, ’leaving for’, ’moving towards’, ’turning into’, ’walking through’ some place or ’following on’ the flow of spaces. Or, as Edmund H. Bacon has said, the departure point of good town planning should be that the successive towns spaces give rise to a flow of harmonic experiences: present experiences merge with earlier ones and become a step towards a future. Or, again in the words of Donald Appleyard, Kevin Lynch and John R. Myer: “The experience of a city is basically of a moving view, and this is the view we must understand if we wish to reform the look of our cities”.

summary	Simulating the development and the image of architecture and urban design means to show how the environment of the future and the living conditions could develop. At the same time it is part of our task to explain our work to local people and to the public and to passion skills in methods, instruments and knowledge in planning to the next generation of architects, planners and last but not least to discuss and to renew them once more for ourselves. Our aim was also to reflect what we have done since starting the look through the key-hole of endoscopy. Meanwhile this look has been completed since the beginnings in 1993 much more by computer and monitor. It is not the question to take the endoscope or the computer as a methodical and instrumental approach. Nowadays we normally decide to take the endoscope and the computer. In preparing the conference and the workshop we thought that this should now also be the moment not only to inform each other and the participants on methods, tools and best practices in simulating and designing the environment but also to focus on the social and human consequences of perception, movement and use the present urban spaces and the urban space in future. So we proposed the theme “MOTION, E-MOTION and URBAN SPACE” and we invited a scientific expert in experimental psychology to give us some serious reflections and one or another hint on our research themes and methods. The contributions and discussions in the conference showed that the proposal has not only been accepted but has also been completed and enriched especially concerning the theme urban space, it’s processes of usage and it‘s atmosphere. Also in the themes of endoscopy and the research on modelling urban spaces and architecture, meanwhile nearly “traditional” ones, remarkable results were presented and discussed. A very important point of contributions and the following discussions was how to present our subjects to the interested public and to improve our own internal exchange. An object could be to enforce the research tasks in researching together even more.

summary	The colour video recording Urban Simulator in TUT was built very early compared with the development of video systems. A contract for planning the simulator electronics, mechanics and camera systems was made in january 1978 with two TUT students: Jani Granholm (computer science and engineering) and Ilkka Alavalkama (machine design and automation). Ease of control and maintenance were asked by side of ”human movement inside coloured small-scale architectural models”. From the beginning, all components of the system were carefully tested and chosen from various alternatives. Financial resources were quite limited, which lead to a long building process and to self-planned and produced mechanical and electronical elements. Some optical systems were constructed by using elements from various manufacturers.

title	An approach to evaluating exhibition spaces in art galleries
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	There are certain building types in which movement of people is the most significant evaluation factor. Among these are art galleries and museums. Unlike other building types, which are often explicated by investigating the relationship between people and people, and between people and the built environment, art galleries and museums are a building type in which the social relationship between people hardly exists and peoples movement through space, that is, the functional relationship between people and space, is one of the most significant factors for their description. The typical museum experience is through direct, sequential, and visual contact with static objects on display as the visitor moves. Therefore, the movement pattern of the visitors must exert a significant influence on achieving the specific goal of a museum. There is a critical need for predicting the consequences of particular spatial configurations with respect to visitors movement. In this sense, it is the intention of this paper to find out the relationship between the spatial configuration of exhibition space and the visitors' movement pattern.

title	Computational Issues in Urban Design: Developing a Strategy for Solar Impact Assessment
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 543-555
summary	A comprehensive method for identifying the impacts on solar access of large scale architectural projects still continues to be an important and controversial area in city planning and urban design. Previous research studies such as the Sun Wind and Pedestrian Comfort, a study of Toronto's Central Area, demonstrated approaches possible when dealing with solar issues related to urban design. Existing techniques for solar inventory, analysis and evaluation, while effective, are often dependent on single event analysis (shadow casting) or manual procedures that are time consuming and exceedingly complex especially when needed for day-to-day use by planners or architects involved in complex urban projects. The Centre for Landscape Research has undertaken as part of its research to develop a computational approach that would help city urban designers evaluate and represent the issues of solar access in an urban setting. This paper will outline a series of computational methods developed to utilize an existing municipal digital data base and to describe complex issues of solar access in terms of urban form and context. A technique will be described that quantitatively assesses the total solar potential of a site as compared to changes in solar access due to different urban design proposals. Two-, three- and four-dimensional representation techniques are developed to facilitate understanding of the analysis to users such as city officials, the public, developers, etc.

title	A decision-making process for choice of a flexible internal partition option in multi-unit housing using decision theory techniques
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Recent demographic changes have increased the heterogeneity of user groups in the North American housing market. Smaller households (e.g. elderly, single parent) have non-traditional spatial requirements that cannot be accommodated within the conventional house layout. This has created renewed interest in Demountable/Flexible internal partition systems. However, the process by which designers decide which project or user groups are most suited for the use of these systems is quite often complex, non-linear, uncertain and dynamic, since the decisions involve natural processes and human values that are apparently random. The anonymity of users when mass housing projects are conceptualized, and the uncertainty as to the alternative to be selected by the user, given his/her constantly changing needs, are some contributing factors to this effect. Decision Theory techniques, not commonly used by architects, can facilitate the decision-making process through a systematic evaluation of alternatives by means of quantitative methods in order to reduce uncertainty in probabilistic events or in cases when data is insufficient. The author used Decision Theory in the selection of flexible partition systems. The study involved a multi-unit, privately initiated housing project in Montreal, Canada, where real site conditions and costs were used. In this paper, the author outlines the fundamentals of Decision Theory and demonstrates the use of Expected Monetary Value and Weighted Objective Analysis methods and their outcomes in the design of a Montreal housing project. The study showed that Decision Theory can be used as an effective tool in housing design once the designer knows how to collect basic data.

title	On the Correlation of Design and Computational Techniques in Architectural Education
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi	https://doi.org/10.52842/conf.ecaade.1993.x.g6i
summary	Many studies employ analyses of human intelligence as justification or guideline for the development of machine intelligence. The main benefit brought on by such studies has been the improvement of our understanding of both human and machine intelligence. In teaching architecture with computers the same approach can make explicit design techniques architects use by means of equivalent or similar computational techniques. Explicitation of design techniques leads to a better understanding of architects' activities, as well as to which computer tools can offer automated support to these activities. In the curriculum of the Faculty of Architecture, Delft University of Technology, relations and correspondences between computational and design techniques form a major underlying theme in computer-aided design courses. The purposes of this theme are (i) comprehension of the computational structure of a computer design tool, and (ii) explanation of how such computational structures relate to architectural design. (correspondences between the computational principles of computer programs and design techniques are instrumental in defining the scope of each computer tool in architectural design while improving the students' understanding of architectural design as a cognitive process and thus promoting automation as a natural extension of established conventional practices. The paper outlines the correlation of computational and design techniques in the case of electronic spreadsheets. Spreadsheets are introduced through a thorough presentation of the various kinds and aspects of constraint propagation, their underlying computational principle. Numerical constraint propagation is explained by means of spreadsheet applications for simple numerical calculations. Symbolic constraint propagation is presented in the framework of machine perception. Both forms are then linked to architectural design through parametric design and the recognition of spaces in floor plans. Exercises linked to spreadsheets and constraint propagation include the parametric calculation of stairs and making parametric variations of a building on the basis of floor area calculations.

title	Understanding Structural Movement Joints with CAAD Animation
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi	https://doi.org/10.52842/conf.ecaade.1993.x.p3d
summary	The well-established use, as an architectural design tool, of computer graphics using 'fly-through' techniques gives a highly visual overview of design concepts and may additionally illustrate certain specific details, but it cannot show their time-dependent dynamic function. This paper describes and illustrates how CAAD animation can be used to analyse not only structural philosophy but also the dynamic effects of nonstatic loading and thermal movement, thus leading to a better understanding of the design criteria applied in certain elegant solutions. The CAAD video animations illustrate the structural philosophy relating to the facade of the refurbished Bracken House, London and the dynamic operation of key movement junctions within Stansted Airport and East Croydon Railway Station.

summary	People’s voluntary movement through an environment is essential for their comprehension of three dimensional space. It may be hypothesized that they move and look around in order to pick up wanted information at the time. This study investigated the following more specific hypotheses by an experiment using a user-controlled space-sequence simulator and the analysis of the subjects’ behavioral data recorded by the simulation system: (1) The strategy of visual search behavior (body movement and viewing direction) is influenced by spatial structure (form and organization). (2) The strategy can be explained by the amount of visual information in the environment, i.e., people move and look in a certain direction in order to maximize effective information at a given moment and position. - If these hypotheses are supported, we can predict people’s behavior in an unfamiliar place on the basis of the spatial structure.

summary	Every architectural design consists of spaces and series of successive spaces. The way in which spaces are arranged to form a series can only be experienced by passing through them. This means that movement plays a very important role in the experience of our spatial environment. At the same time, this presents a major challenge to architects, and especially to students in architecture, who need to take into consideration how their designs are experienced in movement. Therefore, at the Department of Architecture in Tampere one of our aims in Architectural Design is to teach our students to see the spaces, masses, houses and housing areas they design from the point of view of movement. This training has mainly been provided in the context of a Basic Course and Professional Course I in Architectural Design and the related course on Time and Motion in Architecture. Projects related to the theory of time and motion are started with students in their first and second year. A major role in all this teaching has been played by our environmental simulator, with which we have been able to evaluate our work by using models on different scales (1/200, 1/100, 1/500). We have applied three main perspectives in our courses: analysis of space, series of spaces, and series of spaces in motion.

summary	How do we know what we are looking at while viewing inside Building Information Modelling (BIM) models? Current architectural software typically provides disconnected methods of aiding spatial cognition. There is a strong history of navigation tools developed for controlling our exploration and movement in BIM models, a study by Ruby Darken and John Sibert (1993) found these tools had a strong influence on people's behaviour and understanding of digital space. People perceive and navigate space differently depending on their individual experience with a BIM model, designers and architects build up a detailed cognitive map during the design of a project, while other people have a less detailed comprehension of a project, having only been exposed to select views. This paper will outline key strategies to improve how people comprehend digital space, supporting people in understanding distance and size while inside BIM models. Three design research projects will be presented. The result of the projects define three strategies; Architectural wayshowing, interior-aware transitions, and distance confirmation. Architectural wayshowing needs to be implemented during the design phase, while the remaining two need to be introduced into BIM editing and viewing software.

title	The Changing Image of the City
source	University of Utrecht
summary	The image and structure of a town are constantly subject to a dynamic process of change and continuity. Visual material, such as photographs, historical maps, town plans, drawings and prints, show us the impact of these changes on the image of a town. The main point of departure of this study stems from the question of how this process of change and continuity is visually detectable in a town or city. The fact that the ideas about the appearance of a city (gradually) change, can be read from the often subtle changes in the townscape. Though in many cases we have a general knowledge of the choices made in urban management, the most difficult problem is to detect the underlying decisions. This raises the question to what extent these changes and also the continuities are the result of deliberate choices in urban management and to what extent they are autonomous developments in the townscape resistant to interventions. Using different kinds of visual information as a basis, computer visualization techniques are used in the present study to examine some cartographic maps and to reconstruct the urban development in the twentieth century of the town of Heusden three-dimensionally in significant phases. The resulting visualization provides us with a tool for a better understanding of the dynamics of urban transformation processes, typologies and morphological changes and continuities.

summary	Nature as complete entity having existed before us, having produced us, of which we are a part of and which reaches far beyond us and our knowledge stands both for productivity and product, for stones, earth, water, air, plants, animals, human beings, for energy as such. On account of his activity and his intellectual powers and faculties the human being represents the center of this interrelation comprising his vital space, being perceived by him either consciously or unconsciously, the structure and formation of which he changes, which in turn, however, significantly codetermines his behavior and also his development. Spatial effect analysis and spatial impact analysis take the cross- linked interrelations of nature into account and thus the correlated diverse interactions by means of integral representation, determine the direct and indirect as well as the immediate and mediate decisions as to space and furnish us with decision-conclusions by means of modifications. Based on the all-in-all outlook encompassing nature- mankind-space spatial impact also means in particular compatibility within systems giving due regard to the factor time. The following topics are treated within the framework of research: (1.) Elaboration of a methodical framework regarding research and development in the field of multimedia-implementation for environmental planning. (2.) Preparative work concerning implementation areas of multimedia focussing on urban & regional planning and architecture. (3.) Planning process and planning levels,furthermore in the fields of information and decision process and accompanying verification. (4.) Optimizing interaction of multimedia and environmental simulation. (5.) Definition of research- and development-requirements as far as subject-specific and EDP-technical aspects are concerned. (6.) Structurizing of projects regarding realization of framework of research.

title	The Relation Between the Internet Infrastructure and the Internet Industry
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	The scene is set by a survey of new location factors for mobile investment in Europe, published by the European Commission in 1993. This leads to two questions the first of which concerns the exact definition of the Internet industry in order to avoid confusion. The definitional issue appears to be far from simple. The second question is about the Internet infrastructure. This infrastructure, although new and almost invisible, can nevertheless be mapped and measured with less ambiguity than the Internet industry. How to connect the two? How to establish the importance of the Internet infrastructure for the location of the Internet industry? Technological determinism and urban dissolution are debunked as myths. A conceptual innovation is called for: to conceive of the connection between infrastructure and industry as a match between networks. By way of conclusion, this match is discussed from the viewpoint of non-hub cities or regions.

title	Traffic Flow Landscapes
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	Major metropolitan areas and constituent independent jurisdictions face the problem of providing efficient transportation for their residents and in-and out commuters. A typical trip taker spends considerable time on the road to reach the workplace and other destinations. Though it may seem counter-intuitive, adding more links to existing road networks and/or increasing traffic capacity by adding lanes does not necessarily decrease travel times (eg. Braess' paradox). But it is certain that a dense redundant network of roads would provide a trip taker with alternate routes when traffic incidents occur. These types of questions raise the question of, how to evaluate the flow characteristics of the entire road network of a jurisdiction and its larger region in keeping the traffic moving? Further, how may the impact of adding more links/ lanes or the blocking of existing links! lanes be best measured? To answer these and related questions, we propose a methodology to evaluate a fitness criteria for road networks based on Kauffman's biological NK model (1993). We specify a transportation road traffic flow landscape analogous to the fitness landscape of the NK model. Using the transportation road traffic flow landscape we derive a road fitness index that can be used to evaluate either the entire road network's traffic flows or subparts of such network's traffic flows. We explore the possibility of investigating traffic flow landscapes to search for optimal routes to clear traffic. Finally we describe an approach for applying the theoretical framework developed in the paper to the traffic conditions on the road network of the city of Fairfax, Virginia.

title	Efficiency of Model Endoscopic Simulation - An Experimental Research at the University of Stuttgart

summary	At the Institute of Urban Planning at the University of Stuttgart early experiments were made with the help of endoscopes in the late 1970’s. The intention was to find new instruments to visualize urban design projects. The first experiment included the use of a 16 mm film of a 1:170 scale model of the market place at Karlsruhe, including design alternatives (with trees, without trees etc). The film was shown to the Karlsruhe authorities, who had to make the decision about the alternatives. It was said, that the film gave a great help for the decision-making and a design proposition had never before been presented in such understandable way. In 1975-77, with the support of the Deutsche Forschungsgemeinschaft (German Research Foundation) an investigation was carried out into existing endoscopic simulation facilities, such as those in Wageningen, Lund and Berkeley. The resulting publication was mainly concerned with technical installations and their applications. However a key question remained: ”Can reality be simulated with endoscopy?” In 1979-82, in order to answer that question, at the Institute was carried out the most extensive research of the time, into the validity of endoscopic simulation. Of special importance was the inclusion of social scientists and psychologists from the University of Heidelberg and Mannheim. A report was produced in 1983. The research was concerned with the theory of model simulation, its ways of use and its users, and then the establishment of requirements for effective model simulation. For the main research work with models or simulation films, psychological tests were developed which enabled a tested person to give accurate responses or evidence without getting involved in alien technical terminology. It was also thought that the use of semantic differentials would make the work imprecise or arbitrary.

summary	Perception is essential to being in the world — through perception we are in the world. Perception is our way to understand reality and to acquire knowledge of it and be in interaction with the environment. Experiencing architecture is based on perception: the spatial orientation, identification and representation which together make possible our environmental experience. Architecture is not only seeing, but also experiencing. Environmental endoscopy makes it possible to study the environmental orientation, the spatial elements of the environment, but the identification and the representation which are included essentially in the overall perception of the environment presuppose the actual experience of the environment. This presentation discusses all these three levels of the spatial experience. In architecture, space can be discussed in many different ways: we can talk about, for example, architectural space that includes inside and outside space; we can discuss urban space that includes the physical structure of the whole built environment or we can talk about what has been called existential space, that includes the relationship between man and his physical environment. In this presentation space is considered in its wide, experience based meaning: space as the environment of perception, the interaction between man and space, or as a kind of cognitive space theory. Most essential in this discussion is the experience of place, the feeling of place, and its origins, since place is the most unique experience of space, it is man’s deepest experience of the environment.
