title	Towards a Living Architecture
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 164-173

summary	Interaction is the latest currency in architecture, as responsive components are now reacting to the inhabitant of the space. These components are designed and installed by the architect with a view to the phenomenology of space, where the experience of the environment is previewed and pre-constructed before it is translated into the conception of the space. However, this traditional approach to new technology leaves no scope for the architecture to be alive in and of itself, and thus the installed piece quickly becomes just that—an installation: isolated and uncontained by its environment. In this paper, we argue that a way to approach a responsive architecture is to design for a piece that is truly living, and in order to propose a living architecture first we need to understand what the architecture of a living system is. This paper suggests a conceptual framework based on the theory of Autopoiesis in order to create a “self-producing” system through an experiment entitled, “The Life of a Wall” (Maturana and Varela 1980). The wall has a responsive membrane controlled by a genetic algorithm that reconfigures its behaviour and learns to adapt itself continually to the evolutionary properties of the environment, thus becoming a situated, living piece.

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,

title	The Adjacency Topological Model for Housing Layout and Its Generating Algorithm, Based on the Case Study of Chinese Apartment Layouts Since 90s
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.r9v
summary	Our research deals with the problem of space layout planning and chooses the Chinese apartment layouts_since 90s_ as our case study objects. A new kind of data structure for building layouts is proposed which records the adjacency topological information of layouts. The most important quality of our model is that its phenotype corresponds to our visual perception about space layouts which makes possible the morphological analysis and layouts generation. Based on constraint satisfaction techniques the Generating Algorithm focused on enumerating all the possible topology models, under the constraints of program for a new housing layout design. A case study is presented before the conclusion is given.

title	Temporary Housing Design and Planning Software for Disaster Relief Decision Support System
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.k9q
summary	There is a continuous and urgent need for disaster relief in Thailand and countries suffering from floods and tsunami impact. Based on this issue, design and planning software for temporary housing project has been developed, as well as the process and guideline for implementation. This paper describes a unique coupling of interactive 3D virtual environment with parametric designing in order to manage disaster relief project more efficiently. Architects and planners can use the functionality of software on both design simulation and project evaluation aspects. We need to provide correct information to help people making decision when they are in disaster. So the disaster relief decision support system must offer proper information of crisis management focused on people, place, and process. One of the main features of software is the relationship modeling of essential factors such as number of people, houses, budget, time, and space. This automatic temporary houses generation and space planning is simulated for land use and layout plan design with cost estimation analysis. The system components were proposed to a new disaster relief system in alternative approach. Using community-based development will not cost budget but required people participation. Our software’s space coordination will start and centered from available space in school or temple with sufficient infrastructure. After essential factors are inputted, appropriated number of temporary houses, public facilities, and management guideline will be generated to support further planning decision. Our core system was developed on Java and Swing Technology, empowered by real-time 3D rendering CAD engine. In addition, “Virtools” as our Authoring Tools was applied to improve design interaction and explore rapid software prototyping. At the end, we discuss the comparison between real situations in Thailand and appropriate design standardization, which should be reconsidered how to manage crisis with the limitation of time and budget from government.

title	Sketch-based Methods for Researching Building Layouts through the Semantic Fingerprint of Architecture
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 85-102.
summary	The paper focuses on the early stages of the design process where the architect needs assistance in finding reference projects and describes different aspects of a concept for retrieving previous design solutions with similar layout characteristics. Such references are typically used to see how others have solved a similar architectural problem or simply for inspiration. Current electronic search methods use textual information rather than graphical information. The configuration of space and the relations between rooms are hard to represent using keywords, in fact transforming these spatial configurations into verbally expressed typologies tends to result in unclear and often imprecise descriptions of architecture. Nowadays, modern IT-technologies lead to fundamental changes during the process of designing buildings. Digital representations of architecture require suitable approaches to the storage, indexing and management of information as well as adequate retrieval methods. Traditionally planning information is represented in the form of floor plans, elevations, sections and textual descriptions. State of the art digital representations include renderings, computer aided design (CAD) and semantic information like Building Information Modelling (BIM) including 2D and 3D file formats such as Industry Foundation Classes (IFC) (IAI, 2010). In the paper, we examine the development of IT-technologies in the area of case-based reasoning (Richter et al., 2007) to provide a sketch-based submission and retrieval system for publishing and researching building layouts including their manipulation and subsequent use. The user interface focuses on specifying space and their relations by drawing them. This query style supports the spatial thinking approach that architects use, who often have a visual representation in mind without being able to provide an accurate description of the spatial configuration. The semantic fingerprint proposed by (Langenhan, 2008) is a description and query language for creating an index of floor plans to store meta-data about architecture, which can be used as signature for retrieving reference projects. The functional spaces, such as living room or kitchen and the relation among on another, are used to create a fingerprint. Furthermore, we propose a visual sketch-based interface (Weber et al., 2010) based on the Touch&Write paradigm (Liwicki et al., 2010) for the submission and the retrieval phase. During the submission process the architect is sketching the space-boundaries, space relations and functional coherence's. Using state of the art document analysis techniques, the architects are supported offering an automatic detection of room boundaries and their physical relations. During the retrieval the application will interpret the sketches of the architect and find reference projects based on a similarity based search utilizing the semantic fingerprint. By recommending reference projects, architects will be able to reuse collective experience which match the current requirements. The way of performing a search using a sketch as a query is a new way of thinking and working. The retrieval of 3D models based on a sketched shape are already realized in several domains. We already propose a step further, using the semantics of a spatial configuration. Observing the design process of buildings reveals that the initial design phase serves as the foundation for the quality of the later outcome. The sketch-based approach to access valuable information using the semantic fingerprint enables the user to digitally capture knowledge about architecture, to recover and reuse it in common-sense. Furthermore, automatically analysed fingerprints can put forward both commonly used as well as best practice projects. It will be possible to rate architecture according to the fingerprint of a building.

title	Structural Analysis as Driver in Surface-based Design Approaches
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 109-115
doi	https://doi.org/10.52842/conf.ecaade.2007.109
summary	This ongoing research argues for novel strategies to integrate structural analysis data in an architectural design approach. Instead of a linear procedure of synthesis, analysis and post-rationalisation a synthesis/analysis loop is installed that uses structural analysis data as design driver from early on. The approach is not aiming for a pure force-driven form-finding or optimization process but regards structural performance as one design criteria among others. Equilibrium between multiple parameters is aspired instead of a single-parameter-optimum. The research is conducted by a custom-made digital interface between a 3d modelling software and an application for structural analysis of space frames structures. Surfaces are translated into meshes with supports at user-defined nodes and then exposed to its dead load in the structural analysis software. The resulting nodal deviation is feed into an algorithm that steers the appropriate reaction towards the local stresses and deviations, taking into account the mesh topology, its supports and their position in the mesh. The initial mesh is optimized in shape transformed back into a double-layer surface model in the 3d software which evolves into an interconnected two-layer space frame. An instant feedback from synthesis to analysis and vice versa is installed. Analysing techniques migrate into the realm of synthesis.

title	Mining a Collection of Animated Sketches
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 447-456
doi	https://doi.org/10.52842/conf.ecaade.2007.447
summary	How can we make a set of digital assets useful for teaching and research? As we amass data, it is crucial to select and interpret what is presented. This paper describes how a collection of animated drawings has been made accessible through an iterative development process. It describes a Web matrix interface, interpreted lesson formats and an assessment method. The assessment method of tallying achievement on design criteria before a lesson reveals inherent challenges of the problem, tallying afterwards reveals the effectiveness of the lesson in addressing those challenges. Using space-planning layout problems, we found that students readily picked up simple graphic devices such as measurement grids, adjacency diagrams and thumbnail sketches. Students showed less immediate improvement on skills that require juggling of multiple criteria, such as meeting all programmed area size requirements.

doi	https://doi.org/10.52842/conf.ecaade.2007.335
summary	This paper sets out an approach to urban modelling derived from early work with cellular automata and agglomeration models. In these cases the models are an example of distributed representation, where the rules built in to the model are replicated in all the discrete components of the model be they cells or agents. This is the classic AI. / AL paradigm of emergent systems. The paper describes the main structure of the models, and presents examples of the use of this modelling process in design education, pointing out the way dynamic models allow mapping on to interesting speculations about the dynamic of the city, and its social systems. The paper ends with a report on the use of such models as a design decision support system and how they will be used in planned work in master planning in the London Thames gateway area under the UK govt. sustainable communities initiative.

summary	In this paper, we introduce Morphosis: A Responsive Membrane, which physically responds to movement, light and sound interacting spatially and temporally with the environment and their inhabitants. The fundamental hypothesis is to create architectural systems as living, evolving materials. The dynamic of the material is produced by dozens of actuators made by Shape Memory Alloys (SMAs) and LED’s which react in real time to change the behavior of the membrane. The system is controlled by a genetic algorithm in an attempt to develop a technological approach to performance skins that possess adaptive and evolutionary personality relative to changing phenomena of the environment of buildings.

title	Preservation of existing buildings through methods of Operations Research
source	DACH 2007, International Conference on Digital Applications in Cultural Heritage, P. 157-175
summary	The revitalization of existing buildings is getting more and more important. We are facing a situation where in many cases there is no need to design new buildings because an increasing number of existing buildings is not used anymore. The most ecological procedure to revitalize these buildings would be through a continuous usage and by making few or no alterations to the stock. Thus, the modus operandi could be named a “non-destructive” approach. From the architects’ point of view, non-destructive redesign of existing buildings is time-consuming and complex. The methodology we developed to aid architects in solving such tasks is based on exchanging or swapping utilization of specific rooms to converge in a design solution. In this regard, it was examined whether solutions for reuse tasks can be produced automatically by the use of optimization processes in floor plan design. These solutions shall be produced by swapping of existing areas. The objective is to obtain feasible planning solutions by means of these computer-based processes, which will serve the architect as a basis for the further editing of the plans. The methodical basis for this procedure is formed by models from Operations Research. The design of the model developed relates to problems in logistics, for example, the loading in trans-shipment centers. It also has analogies to board games like Chess or Go. These games are based on a specific number of fields or crosses of grid lines which are occupied by various tokens. Occupation is subject to a variety of conditions or rules. Compliance to conditions and objectives is clearly defined by the use of these rules. The analogy to our model is the fixed grid, the limited possibility to occupy fields and the fulfillment of an overall goal, i.e., to win the game. Therefore the model does not alter geometric proportions or locations of rooms but changes their occupancy such that a new usage could be applied to the building.

title	A Shape Grammar of Emotional Postures - An approach towards encoding the analogue qualities of bodily expressions of emotions
source	Fioravanti, A, Cursi, S, Elahmar, S, Gargaro, S, Loffreda, G, Novembri, G, Trento, A (eds.), ShoCK! - Sharing Computational Knowledge! - Proceedings of the 35th eCAADe Conference - Volume 2, Sapienza University of Rome, Rome, Italy, 20-22 September 2017, pp. 485-492
doi	https://doi.org/10.52842/conf.ecaade.2017.2.485
summary	This paper is concerned with the translation of analogue qualities of human emotions into digital readings. Human body postures are considered as one of the main behavioral conduits for non-verbal communication and emotional expressions (Shan et.al., 2007). This research is the first step towards identifying and detecting emotions through posture analysis of users moving through space; leading towards generating real time responses in the form of spatial configurations to users' emotions. Such spatial configurations would then help inhabitants reach certain emotional states that would enhance their life quality. In order to achieve this goal, we propose a methodology for developing a comprehensive shape grammar algorithm that could evaluate and predict bodily expressions of emotions. The importance of this study lies under the embodied interactions (Streech et.al., 2011) in space. As the circumfixed space impacts the embodied mind, the body impacts its surrounding including the architectural space.

doi	https://doi.org/10.52842/conf.ecaade.2007.507
summary	This paper focuses on optimization methods and their role in the “digital chain” in architectural design and production. These methods were developed in the research phase of the project ‘New Monte Rosa Shelter’ to improve cost efficiency and to adapt the design for the specific environmental and constructive constraints of the site. The New Monte Rosa Shelter is a project designed by students for a mountain shelter at high altitude. For transportation and construction reasons, optimization was required to minimize costs, material, and weight of the structure. For this project a series of programs using genetic algorithms were written to optimize the geometry of the wooden framework. These programs were combined to create a digital toolset, giving the architects direct output of surface information from the framing data, and allowing for output as a three-dimensional model. This optimization toolset gives creative control back to the architects themselves, who can now transform and manipulate the architecture. This paper describes the overall process, and outlines one specific optimization tool, a program that enables architects to “fill” the wooden framework automatically with different material and construction systems and understand the cost and efficiency implications based upon the structural analysis software and the programmed heuristic methods.

title	Various Media in the Design Process and Methodology
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.t8j
summary	The paper describes the mergence of traditional architectural design processes with approaches that rely on digital media and software for the creation of architectural space. The depicted projects are part of a ‘work in progress’ process, with a recent studio that is set up to apply the so far accumulated experiences. Within the projects, focus is on those design phases where the applied media and methodology is changed and where the back and forth between different media and the depth of their implementation is perceptible in, and / or has a significant influence on the design itself. Through a line of successive experiments, the paper explains the development of a possible method that utilizes a variety of today’s accessible tools in architecture, making use of phenomena that appear when changing from one tool to another. Goal is to avoid limitations that are existent by the solely employment of one media or method, and to understand the fusion between different media as an inspiring momentum to develop the design further. The paper draws a line from an initially experienced and analyzed design method over several projects in practice and academia to conclude with a possible design method that could be established successfully in both fields of architectural teaching and practice. Initial experiences had been drawn from professional practice, in which the digital realm was limited to a support device of the design process. The first project that is described in the paper, explored the employment of digital media as a possible tool to drive the design process in a broader sense. The studio setting was organized as a laboratory for the exploration of the change of applied media. Focus was on the influence on the design progress. The design method required of the studios participants was not exclusively based on an architectural program, but on an initial, very conceptual process with an artistic approach, based on personal experiences of each participant. This was meant to detach the students entirely from architectural processes and mindsets they had picked up so far. Parallel to that kind of an intellectual process, studio participants learned to handle Maya as the 3D modeling software of their choice. Both the technical knowledge and the artistic projects were merged in a second project phase, in which participants had to further develop their work by applying a very effective mix of various design tools. Using digital media as a parametric design generator, subsequent projects were developed. The task for the designers here were to decide what kind of algorithm could be applied to which process and when it was to be stopped for the best result. Applying such an automatism successfully to the design process, the employment of traditional media and methodology remained, to adapt the digital driven schemes to the required design task. The diverse design experiments demonstrate important aspects when merging complex design and animation software with traditional design processes. To achieve good architectural design results, all examined projects showed that traditional design methods with its physical models are hardly replaceable to its full extent by other media, but digital media are able to strengthen design processes and invite designers to explore new means of design work.

summary	This paper presents a situated agent-based tool for design optimization. A situated agent captures, learns from and re-uses the interactions which it has with its external environment, forming the basis for experience-based knowledge building in an agent. An agent is developed for design modeling, reformulation and algorithm selection – a class of tasks in design optimization traditionally performed by humans based on their experience, and hard to automate.

title	Foam Structures: A Comparative Structural Efficiency Analysis Based on the Building Case "Watercube"
source	Vienna University of Technology; Building Science & Technology
summary	Foam structure in macro-scale has arisen as a new type of large span building structure recently which is a product of cooperation of advanced structural design, radical architectural design approach, and computer and software technology, and efficiency of foam structure became an important question to answer which could help further structural improvements. This study analyses efficiency of large span foam structure relative to conventional large span building structures with a parametric simulation method. Space frames are a special case of conventional large span structures one compared with foam structures, because it satisfies criteria such as being lightweight and three-dimensional as foam structure. Analysis is based on the comparison of base cases of foam model and space frame model, which are developed on light of real projects the Water Cube and the Symbol Zone of Expo’70, based on the parameters structural depth, weight and displacement, and vertical and horizontal load cases. During the analysis structural behavior of base cases were simulated by using a special structural behavior simulation program. It was found that foam model is more efficient than space frame model in terms of structural depth which is an important issue for large span building structures from both architectural and engineering point of view. Capability of spanning large distance with significantly less structural depth makes foam structure a preferable, new generation, steel structure for large spans. Moreover, the development process of base case foam model demonstrated the critical importance of geometrical design concerns of foam structure. Structural behavior simulations were exposed that structural optimization is one of the vitally important process of structural design of the foam structure.

title	Genetically Engineered Architecture: design exploration with evolutionary computation
source	VDM Verlag Dr. Mueller, Germany, Dec. 2007. ISBN 978-3-8364-4721-8
summary	This book explores design tools based on evolutionary computation (EC), oriented primarily toward conceptual design of architectural and civil engineering structures. EC tools are well suited for exploration in a way which promotes creative design. The multiplicity of solutions generated by EC techniques is less likely to cause design fixation, and so promote a more thorough exploration of possible solutions. The use of such tools also allows the designer greater latitude in exploring design criteria, such as aesthetics, by utilizing an interactive human-computer interface. This book begins with a survey of techniques that have been used in early phases of architectural design, and establishes a set of successful attributes, which are then discussed in the context of EC techniques. Finally, a specific implementation developed by the author is described. Several examples are given in the area of architectural engineering, and comparisons are made with results obtained with more conventional optimization tools. This book is especially useful for designers interested in new methods for generating and exploring structural form, and is accessible to non-programmers in either field. Dr.-Ing. Peter von Buelow has worked as both architect and engineer, and is currently a professor at the University of Michigan in Ann Arbor, USA, where he teaches structures in the School of Architecture, and conducts research in structural form exploration based on evolutionary computation.

summary	This paper presents a novel approach to digital investigation of body, space, form and motion to expose issues of spatial perception. The spatial experience as generated from, and translated by, the human body is the focus of this work. The work explores the representational value of the body’s sense-image, the context and spatial/visual literacy of the learned sense of space-time generated from the study of the human body. Here the body is conceived not just in space but also in time, affording the ability to reinterpret the body and it’s dynamic motion engaged not as a static condition, but as a set of event spaces. Motion here is defined as a multiplicity of continuities that can be subdivided by artificial boundaries that describe space, time and body. The study of a series of bodies and movements is described that explore the human condition as a series of differential lines (form + time) and framed structures (bodies + motion). The intention is to examine the relationship between human form and metaphysical simultaneity as generators of architectural form. The work is structured by a research approach that dissects and isolates the representational concept/image from the body in a way that might offer an alternative description to the traditional historic models.

summary	This research, focus on the automation of passive solar design system using computational method. The quantitative nature of passive solar design system makes the automation possible. The automation is done in stages, because implementing the passive solar design system is not an isolated process, but intertwined with the overall design process. The first phase of automation concentrates in conceptual stage, to avoid major deviations in later stages of the design. The conceptual stage use Eco-grammar (A preset Design guidelines for corresponding climate) and user inputs for initial form generation. The second stage of automation is done after the user finalize the model with respect to its position rotation and arrangements. In this stage manipulation of vertex, edges and faces of the forms were manipulated using genetic algorithm. The value of mutation or crossover done in genetic algorithm is suggested by knowledge engine (preloaded design knowledge). Until the form obtains or reach closer to the desired values of performance the loop between analysis and mutation, crossover will be continued. On the basis of analysis result further manipulations may change from the previous which is guided by the knowledge engine.

title	Architecture and the Culture of Contingency

summary	A culture is a set of behaviours, attitudes and values that are shared, sustained and transformed by an identifi able community. Currently, we are bound up in a culture of consumerism, and of terror; there are also retro cultures and utopian cultures. What’s happening now that’s interesting is that many, if not all of these diff erent tendencies, tastes and persuasions are being re-aligned, interconnected and hybridised by a vast global community of online users, who are transdisciplinary in their approach to knowledge and experience, instinctively interactive with systems and situations, playful, transgressive and enormously curious. This living culture makes it up as it goes along. No longer do the institu- tions of state, church or science call the tune. Nor can any architectural schema contain it. This is a culture of inclusion and of self-creation. Culture no longer defi nes us with its rules of aesthetics, style, etiquette, normalcy or privilege. We defi ne it; we of the global community that maps out the world not with territorial boundaries, or built environments, but with open-ended networks. This is a bottom-up culture—non-linear, bifurcating, immersive, and profoundly human. Who needs archi- tecture? Any structural interface will do. Ours can be described as a contingent culture. It’s about chance and change, in the world, in the environment, in oneself. It’s a contingent world we live in, unpredictable, unreliable, uncertain and indeterministic. Culture fi ghts back, fi ghts like with like. The Contingent Culture takes on the contingency of life with its own strategies of risk, chance, and play. It is essentially syncretic. People re-invent themselves, create new relationships, new orders of time and space. Along the way, they create, as well as accommodate, the future. This culture is completely open-ended, evolving and transforming at a fast rate—just as we are, at this stage of our evolution, and just as we want it to be. Human nature, unconstrained, is essentially syncretic too.

title	Experimental Results in Immersive Virtual Reality (IVR): Searching Critical Design Factors within IVR to Increase Architectural Space Qualities
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 91-98

summary	The actual study in IVR (Immersive Virtual Reality) proposes a path which may provide meaningful information about the user’s behaviours and difficulties to articulate in immersive worlds. Beyond it, we are searching for parameters to improve design qualities in such an architectural space. Our interest is to use IVR as a medium to research the quality of spaces in particular the atmosphere of such spaces, on the basis of people’s interest and eagerness. Therefore it is important to comprehend the special conditions of the perception and the behaviour of the user in virtual spaces. The purpose is to understand the influence of an IVR environment upon the human being and to develop motivation for a personal use of virtual space as a learning environment. The aim of the analysis was to explore behaviour patterns in a simulated IVR environment. Moving from the dynamic of space, there arises a personal “space-time-system”.
