title Frictions and Frustrations in Creative-Informatory Work with Computer Aided Design -- CAD-Systems -- Congress I: Work with Terminals: HEALTH ASPECTS: WORKLOAD, STRESS AND STRAIN AND IRREGULAR WORKING HOURS; Causes and Measures of Stress

summary The effects of computer aided design work on the design process are analysed by field experiments. The study focuses on the influence of 3 different design tasks (standard tasks) and 11 CAD-systems (2D and 3D), taking into account the performance and strain measurements of 43 subjects (15 design engineers, 8 technicians, 17 draughtsmen, 3 trainees). The 3 standard tasks differ in performance measurements, especially in time spent on task, quantity of generated elements, not in the quality of the solution. The kind of CAD-system influences the time spent on task as well as the design performance, with significant differences of up to 100%. The same tendency can be diagnosed in a comparison of 2D and 3D systems. During the use of different functions of the CAD-system, strain effects are identified by cross-correlation with continuously measured physiological parameters, even with CAD-functions which should reduce stresses of routine work. Deficits and complications in the handling of CAD-systems increase with the complexity of the system and thus cause an antinome effect on performance and strain of its operators: creativity is reduced by frictions and frustrations in system handling even if operators are highly trained.

summary Virtual reality offers considerable promise with regard to facilitating the building process. A good example is the facilitation of communication between architects and building companies, sellers and buyers or between community planners and the general public. It is often thought that in order to utilise the potential of VR in, for example, the above-mentioned contexts, it is necessary to use fully fledged versions of VR, including stereovision and the possibility of controlling the VR show. However, if a model can also be presented on less advanced equipment and still interpreted in a way that is useful to the viewer it will be possible to distribute the model simply and effectively. This would make it easier to create a more democratic urban planning process compared with if specialised equipment needed to be used and special shows needed to be arranged. In this study we compared the experience of two VR models (a large indoor exhibition hall and an outdoor street in Gothenburg, Sweden) when presented with and without stereovision. When the experience was measured using the Semantic Environmental Scale (the SMB scale, developed by Küller, 1975, 1991), questions on the experience of presence and six other questions on the experience of the models, the results only revealed one indication that stereovision made a difference. This indication was the result for the SMB factor Enclosedness. Suggestions are presented for future research in this area.

title Bridging GIS-based landscape analysis/modelling and 3D-simulation.Is this already 4D?
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary Several studies have used remote sensing to map patterns of e.g. deforestation or to analyse the rates of land use change. Thesestudies have proven useful for interpreting the causes of urbanization, deforestation etc. and the impact of such changes on theregion. Monitoring of change (e.g. deforestation or reforestation) is frequently perceived as one of the most important contributionsof remote sensing technology to the study of global ecological and environmental change (Roughgarden et al. 1991). Manyresearchers believe that the integration of remote sensing techniques within analysis of environmental change is essential if ecologistsare to meet the challenges of the future, specifically issues relating to global change; however, in practice, this integration has so farbeen limited (Griffiths & Mather 2000). Considerable difficulties are encountered in linking, on the one hand, the biologies oforganisms and the ecologies of populations to the fluxes of material and energy quantifiable at the level of ecosystems. In this paper,we concentrate on the methodological aspects of the delineation of landscape objects and touch the ecological application onlysuperficially but we elucidate the potential of the proposed methodology for several ecological applications briefly.

title Analogical and inductive reasoning in architectural design computation
source Swiss Federal Institute of Technology, ETH Zurich
summary Computer-aided architectural design technology is now a crucial tool of modern architecture, from the viewpoint of higher productivity and better products. As technologies advance, the amount of information and knowledge that designers can apply to a project is constantly increasing. This requires development of more advanced knowledge acquisition technology to achieve higher functionality, flexibility, and efficient performance of the knowledge-based design systems in architecture. Human designers do not solve design problems from scratch, they utilize previous problem solving episodes for similar design problems as a basis for developmental decision making. This observation leads to the starting point of this research: First, we can utilize past experience to solve a new problem by detecting the similarities between the past problem and the new problem. Second, we can identify constraints and general rules implied by those similarities and the similar parts of similar situations. That is, by applying analogical and inductive reasoning we can advance the problem solving process. The main objective of this research is to establish the theory that (1) design process can be viewed as a learning process, (2) design innovation involves analogical and inductive reasoning, and (3) learning from a designer's previous design cases is necessary for the development of the next generation in a knowledge-based design system. This thesis draws upon results from several disciplines, including knowledge representation and machine learning in artificial intelligence, and knowledge acquisition in knowledge engineering, to investigate a potential design environment for future developments in computer-aided architectural design. This thesis contains three parts which correspond to the different steps of this research. Part I, discusses three different ways - problem solving, learning and creativity - of generating new thoughts based on old ones. In Part II, the problem statement of the thesis is made and a conceptual model of analogical and inductive reasoning in design is proposed. In Part III, three different methods of building design systems for solving an architectural design problem are compared rule-based, example-based, and case-based. Finally, conclusions are made based on the current implementation of the work, and possible future extensions of this research are described. It reveals new approaches for knowledge acquisition, machine learning, and knowledge-based design systems in architecture.

summary During the past ten years computers in architecture have evolved from machines used for analytic and numeric calculation, to machines used for generating dynamic images, permitting the creation of photorealistic renderings, and now, in a preliminary way, permitting the simulation of virtual environments. Digital systems have evolved from increasing the speed of human operations, to providing entirely new means for creating, viewing and analyzing data. The following essays illustrate the growing spectrum of computer applications in architecture. They discuss developments in the simulation of future environments on the luminous screen and in virtual space. They investigate new methods and theories for the generation of architectural color, texture, and form. Authors address the complex technical issues of "intelligent" models and their associated analytic contents. There are attempts to categorize and make accessible architects' perceptions of various models of "reality". Much of what is presented foreshadows changes that are taking place in the areas of design theory, building sciences, architectural graphics, and computer research. The work presented is both developmental, evolving from the work done before or in other fields, and unique, exploring new themes and concepts. The application of computer technology to the practice of architecture has had a cross disciplinary effect, as computer algorithms used to generate the "unreal" environments and actors of the motion picture industry are applied to the prediction of buildings and urban landscapes not yet in existence. Buildings and places from history are archeologically "re-constructed" providing digital simulations that enable designers to study that which has previously (or never) existed. Applications of concepts from scientific visualization suggest new methods for understanding the highly interrelated aspects of the architectural sciences: structural systems, environmental control systems, building economics, etc. Simulation systems from the aerospace industry and computer media fields propose new non-physical three-dimensional worlds. Video compositing technology from the television industry and the practice of medicine are now applied to the compositing of existing environments with proposed buildings. Whether based in architectural research or practice, many authors continue to question the development of contemporary computer systems. They seek new interfaces between human and machine, new methods for simulating architectural information digitally, and new ways of conceptualizing the process of architectural design. While the practice of architecture has, of necessity, been primarily concerned with increasing productivity - and automation for improved efficiency, it is clear that university based studies and research continue to go beyond the electronic replication of manual tasks and study issues that can change the processes of architectural design - and ultimately perhaps, the products.

title The visual harmony between new and old materials in the restoration of historical architecture: A study of computer simulation
source AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary In the research of historical architecture restoration, scholars respectively focus on the field of architectural context and architectural archeology (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000) or on architecture construction and the procedure of restoration (Shi, 1988, 1989; Chiu, 1990). How to choose materials and cope with their durability becomes an important issue in the restoration of historical architecture (Dasser, 1990; Wang, 1998).In the related research of the usage and durability of materials, some scholars deem that, instead of continuing the traditional ways that last for hundreds of years (that is to replace new materials with old ones), it might be better to keep the original materials (Dasser, 1990). However, unavoidably, some of the originals are much worn. Thus we have to first establish the standard of eliminating components, and secondly to replace identical or similar materials with the old components (Lee, 1990). After accomplishing the restoration, we often unexpectedly find out that the renewed historical building is too new that the sense of history is eliminated (Dasser, 1990; Fu, 1997). Actually this is the important factor that determines the accomplishment of restoration. In the past, some scholars find out that the contrast and conflict between new and old materials are contributed to the different time of manufacture and different coating, such as antiseptic, pattern, etc., which result in the discrepancy of the sense of visual perception (Lee, 1990; Fu, 1997; Dasser, 1990).In recent years, a number of researches and practice of computer technology have been done in the field of architectural design. We are able to proceed design communication more exactly by the application of some systematic softwares, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and so on (Lawson, 1995; Liu, 1996). The application of computer technology to the research of the preservation of historical architecture is comparatively late. Continually some researchers explore the procedure of restoration by computer simulation technology (Potier, 2000), or establish digital database of the investigation of historical architecture (Sasada, 2000; Wang, 1998). How to choose materials by the technology of computer simulation influences the sense of visual perception. Liu (2000) has a more complete result on visual impact analysis and assessment (VIAA) about the research of urban design projection. The main subjects of this research paper focuses on whether the technology of computer simulation can extenuate the conflict between new and old materials that imposed on visual perception.The objective of this paper is to propose a standard method of visual harmony effects for materials in historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example).There are five steps in this research: 1.Categorize the materials of historical architecture and establish the information in digital database. 2.Get new materials of historical architecture and establish the information in digital database. 3.According to the mixing amount of new and old materials, determinate their proportion of the building; mixing new and old materials in a certain way. 4.Assign the mixed materials to the computer model and proceed the simulation of lighting. 5.Make experts and the citizens to evaluate the accomplished computer model in order to propose the expected standard method.According to the experiment mentioned above, we first address a procedure of material simulation of the historical architecture restoration and then offer some suggestions of how to mix new and old materials.By this procedure of simulation, we offer a better view to control the restoration of historical architecture. And, the discrepancy and discordance by new and old materials can be released. Moreover, we thus avoid to reconstructing ¡§too new¡¨ historical architecture.

title A digital Procedure of Building Construction: A practical project

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

summary In the international student-project "European Environmental Campus 91 TU Delft Dordrecht" 20 students from 13 European countries worked in september 1991, during three weeks on "EcologicalSketches for the Island of Dordrecht". They worked on four different scales: the region isle of Dordt / the district Stadspolders / the neighbourhood I the house and the block. The environmentaltheme's Energy, Water, Traffic & Noise, Landscape & Soil were together with spatial analyses combined with the different scales. This combination was organised following the scheme mentioned below. The characters stand for the students. During the first period they worked in research groups, during the last period more in design groups. For instance: student L works in the beginning with the students B, G and Q in the research group water. In the last period sheworks with K, M, N and 0 in the design group Neighbourhood. Those students worked earlier in the other research-groups and contribute now in the design-group their thematic environmental knowledge. The results were presented to the Dordrecht council, officials and press. In the next project in september and october 1993 we started earlier with the design groups. Ten Dutch and ten "Erasmus" students worked for six weeks on proposals for the Vinex location Wateringenthe Hague. Each morning they worked in the research groups each afternoon in the design groups. The research groups used the EcoDesign Tools, small applications in Excel on Apple Macintoshto quantify the environmental pressure.

summary In 1986 the Faculty of Architecture was established in Maputo. It is financed by the Italian Ministry of Foreign Affairs and managed by a Scientific Council of the Faculty of Architecture of "Università La Sapienza" of Rome. The need to create human technical resources beeing able to work profesionally as soon as they finish their studies, made the teaching basis for lab exercises and design. The new architects (the first six students graduated in 1991), need to design and make very important decisions without any control by more experienced local technical institutions. The creation of a CAAD laboratory, and the teaching of information technologies and metodologies in architectural designing aimes to achieve a double goal: (-) to make the new architects able to manage on their own, because of the lack of qualified human resources, large quantity of data, and difficult design problems; (-) to make University, the most important scientific center in the country, an information exchange center between developped countries, and Moçambique.

title Analysis of design communication with and without computer mediation
source Proceedings of Co-designing 2000, pp. 329-337
summary With recent developments in CAD and communication technologies, the way we visualise and communicate design representations is changing. A matter of great interest to architects, practitioners and researchers alike, is how computer technology might affect the way they think and work. The concern is not about the notion of 'support' alone, but about ensuring that computers do not disrupt the design process and collaborative activity already going on (Bannon and Schmidt, 1991). Designing new collaborative tools will then have to be guided by a better understanding of how collaborative work is accomplished and by understanding what resources the collaborators use and what hindrances they encounter in their work (Finholt et al., 1990). Designing, as a more abstract notion, is different than having a business meeting using video conferencing. In design it is more important to 'see' what is being discussed rather than 'watch' the other person(s) involved in the discussion. In other words the data being conveyed might be of more importance than the method with which it is communicated (See Kvan, 1994). Similarly, we believe that by using text instead of audio as a medium for verbal communication, verbal representations can then be recorded alongside graphical representations for later retrieval and use. In this paper we present the results of a study on collaborative design in three different environments: face-to-face (FTF), computer-mediated using video conferencing (CMCD-a), and computer-mediated using "talk by typing" (CMCD-b). The underlying aim is to establish a clearer notion of the collaborative needs of architects using computer-mediation. In turn this has the potential in assisting developers when designing new collaborative tools and in assisting designers when selecting an environment for a collaborative session.

summary The reference model for CAD systems developed by the Gesellschaft fur Informatik (GI -- the German membership organization of IFIP) is a frame for classifying the functionality of CAD systems. Whereas the reference model regards the user interface as one of several modules of the CAD system, the user interface appears to the user as being the whole system. This is the reason why an additional task working group on CAD user interfaces has been established by the GI in order to develop recommendations for the design of CAD user interfaces. Proceeding and preliminary results of the working group are described.

summary This paper reports on the development of a knowledge based system that can help to assess the reuse potential of idle industrial property. It does not take the place of the architect or engineer, but allows for strategic design factors to be considered in very early and important property redesign and revitalization decisions. The idea is predicated on the judgment that there is a relatively systematic approach to evaluating the reuse potential of vacant property. A frame based approach together with a series of "if-then" rules are used to represent the knowledge domain and procedures required to perform a feasibility analysis. Rules for assessing the impact of the regional economy, industrial market trends, building configuration, building design strategies and the impact of building codes are included in this manner. A prototype of this system system has been implemented on both an Apple Macintosh computer using AAIS Prolog and an IBM AT compatible using Arity/Prolog.

summary Designing is a complicated human behaviour and method, and is often treated as a mysterious "black box” operation in human mind. In the early period as for theory-studying of design thinking, the way of thinking that the researchers took were mostly descriptive discussions. Therefore, they lacked direct and empirical evidence although those studies provided significant exploration of design thinking (Wang, 1995). In recent years as for the study of cognitive science, they have tried to make design "glass box”. That is to try to make the thinking processes embedded in designers publicized. That is also to externalize the design procedure which provided the design studies another theoretical basis of more accurate and deeply researched procedure (Jones, 1992). Hence the studying of design thinking has become more important and the method of designing has also progressed a lot. For example, the classification of the nature of design problem such as ill-defined and well-defined (Newell, Shaw, and Simon, 1967), and different theoretical procedure modes for different disciplines, such as viewing architectural models as conjecture-analysis models and viewing engineering models as analysis-synthesis (Cross, 1991).

summary A fundamental aspect of the expertise of the architectural designer is the ability to assess the quality of existing and developing proposals from schematic representations such as plans, elevations and sections. In this paper I present a computable model of those aspects of the evaluation of architectural floor plans that I believe to be amenable to rule-like formulation. The objective behind the development of this model is twofold: 1) to articulate a belief about the role of simple symbolic representations in the task of evaluation, a task which relies primarily on uniquely human capabilities; and 2) to explore the possible uses of such representations in the development of design expertise. // Input to the model consists of a specification of a design proposal in terms of walls, doors, windows, openings and spaces together with a specification of the context in which the proposal has been developed. Information about context is used to retrieve the goal packages relevant to the evaluation of the proposal. The goal packages encode information about requirements such as circulation, visual privacy and thermal performance. Generic associations between aspects of a plan and individual goals are used to establish if and how each of the goals have been achieved in the given proposal. These associations formalize relationships between aspects of the topology of the artefact, such as the existence of a door between two rooms, and a goal, in this case the goal of achieving circulation between those two rooms. Output from the model consists of both a graphic representation of the way in which goals are achieved and a list of those goals that have not been achieved. The list of goals not achieved provides a means of accessing appropriate design recommendations. What the model provides is essentially a computational tool for exploring the value judgements made in a particular proposal given a set of predefined requirements such as those to be found in design recommendation literature.

source Proceedings of the Conference on Computer Human Interaction (CHI) '91, pp. 217-224,1991
summary A multi-user drawing tool was used by participants in a distributed design exercise conducted in a multi-media working environment. The goal of the study was to explore how observations from our earlier studies of shared drawing in two-person design activity would hold up when three participants worked together. Additionally, the study provided opportunities to contrast video/audio connections with audio-only connections and to discover new behaviors that emerge in the use of new technologies. Participants successfully used the shared drawing system with no observed difficulties attributable to the addition of a third user. Audio-only connections appeared to adequately suppofi this work activity, but details of the participants' interactions in the exercise raised questions that deserve further study. Finally, observations suggest that drawing tools such as the one reported here may offer support for alternative forms of participation in collaborative work.

summary Evolution is now considered not only powerful enough to bring about the biological entities as complex as humans and conciousness, but also useful in simulation to create algorithms and structures of higher levels of complexity than could easily be built by design. In the context of artistic domains, the process of human-machine interaction is analyzed as a good framework to explore creativity and to produce results that could not be obtained without this interaction. When evolutionary computation and other computational intelligence methodologies are involved, every attempt to improve aesthetic judgement we denote as ArTbitrariness, and is interpreted as an interactive iterative optimization process. ArTbitrariness is also suggested as an effective way to produce art through an efficient manipulation of information and a proper use of computational creativity to increase the complexity of the results without neglecting the aesthetic aspects [Moroni et al., 2000]. Our emphasis will be in an approach to interactive music composition. The problem of computer generation of musical material has received extensive attention and a subclass of the field of algorithmic composition includes those applications which use the computer as something in between an instrument, in which a user "plays" through the application's interface, and a compositional aid, which a user experiments with in order to generate stimulating and varying musical material. This approach was adopted in Vox Populi, a hybrid made up of an instrument and a compositional environment. Differently from other systems found in genetic algorithms or evolutionary computation, in which people have to listen to and judge the musical items, Vox Populi uses the computer and the mouse as real-time music controllers, acting as a new interactive computer-based musical instrument. The interface is designed to be flexible for the user to modify the music being generated. It explores evolutionary computation in the context of algorithmic composition and provides a graphical interface that allows to modify the tonal center and the voice range, changing the evolution of the music by using the mouse[Moroni et al., 1999]. A piece of music consists of several sets of musical material manipulated and exposed to the listener, for example pitches, harmonies, rhythms, timbres, etc. They are composed of a finite number of elements and basically, the aim of a composer is to organize those elements in an esthetic way. Modeling a piece as a dynamic system implies a view in which the composer draws trajectories or orbits using the elements of each set [Manzolli, 1991]. Nonlinear iterative mappings are associated with interface controls. In the next page two examples of nonlinear iterative mappings with their resulting musical pieces are shown.The mappings may give rise to attractors, defined as geometric figures that represent the set of stationary states of a non-linear dynamic system, or simply trajectories to which the system is attracted. The relevance of this approach goes beyond music applications per se. Computer music systems that are built on the basis of a solid theory can be coherently embedded into multimedia environments. The richness and specialty of the music domain are likely to initiate new thinking and ideas, which will have an impact on areas such as knowledge representation and planning, and on the design of visual formalisms and human-computer interfaces in general. Above and bellow, Vox Populi interface is depicted, showing two nonlinear iterative mappings with their resulting musical pieces. References [Manzolli, 1991] J. Manzolli.

title An Intelligent Simulation Approach in Simulating Dynamic Processes in Architectural Environments
source Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 177-190
summary The implications of object-oriented data models and rule-based reasoning systems is being researched in a wide variety of application areas ranging from VLSI circuit design (Afsannanesh et al 1990) to architectural environments (Coyne et al 1990). The potential of this approach in the development of discrete event simulations is also being scrutinized (Birtwistle et al 1986). Such computer models are usually called "expert simulations" or "intelligent simulations". Typically rule-basing in such models allows the definition of intelligent-objects that can reason about the simulated dynamic processes through an inferencing system. The major advantage of this approach over traditional simulation languages is its ability to provide direct reference to real world objects and processes. The simulation of dynamic processes in architectural environments poses an additional Problem of resolving the interaction of architectural objects with other objects such as humans, water, smoke etc., depending on the process simulated. Object-oriented approach promises potential in solving this specific problem. The first part of this paper addresses expert simulation approach within the context of architectural settings, then the second part summarizes work done in the application of such an approach to an emergency egress simulation.

title Landscape of the Mind
source Reality and Virtual Reality [ACADIA Conference Proceedings / ISBN 1-880250-00-4] Los Angeles (California - USA) October 1991, pp. 71-86

summary The focus of this article is the exploration of landscape and the question of representation, more specifically how landscape principles can be represented through computation. It is a quest for essential qualities, through an application of philosophical questioning, and a response to a human perception of reality. Reality, as an invention of the human mind, is often thought of as a set of accepted conventions and constructs. Such a reality has an inherent dependency upon cognition where spatial and temporal principles may be defined within the natural and built environment, and further embraced within a cultural context. However, there also exist rules or relations that are neither invented nor formulated by the participants understanding. In effect these relations may not have been effectively articulated, a result perhaps of unfamiliar cues. Therefore, to the participant, these relations reside in the realm of the unknown or even the mystic. The aesthetic often resides in the realm of the mystic. The discovery of the aesthetic, is often an experience that comes from encountering physical and essential beauty where it has been produced through unconscious relations, perceived, yet transcending human understanding. The aspects of space and time, spatial and temporal properties and relations of things and events, are generally accepted conventions. Yet, the existence of a time order, is often not perceived. An understanding of spatial temporal properties may involve a temporal detachment from convention, allowing the release of previously unknown patterns and relations. Virtual realities are well constructed simulations of our environments, yet they may lack the embedded essential qualities of place. Virtual reality should transcend human perception and traditional modes of understanding, and most importantly our limited notions of the temporal nature of our environment. A desire to reach beyond the limits of perceived time order, may take us beyond existing sets of cultural values, and lead to the realization of new spatial/temporal conventions with the assistance of the computer.
