title	Non-Linear Postrationalisation: Architectural Values Emergence in a Teamwork Interpretation
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	The paper presents the outcomes of the experiment being conducted at the Faculty of Architecture in Bialystok, which derives form three main sources: a new course of architectural composition by computer modelling, developed and conducted in Bialystok postrationalisation as a formulation platform for new architectural values and theories, applied by e.g. Bernard Tschumi the idea of new values emergence resulting form a teamwork, when placed in an appropriate environment; It is assumed that the work performed first intuitively, can be later seriously interpreted, and to some extent rationalised, verbalised, described. With no doubt we can state, that in creative parts of architectural activities, very often decision are taken intuitively (form design). So this ‘procedure’ of postrationalisation of intuitively undertaken efforts and results seems to be very important –when trying to explain ideas. This kind of activity is also very important during the first years of architectural education. In case of this experiment, the students’ works from the course of architectural composition are taken as a base and subjects for interpretation, and values research. However, when at first, individual works are being interpreted by their authors, at the latter stage, the teams are to be formed. The aim of the teamwork is to present individual works, analyse them, find common value(s), and represent it (them) in an appropriate, creative way. The ideal environment to perform this work is hypertext based internet, because the non-linearity of team interpretations is unavoidable. On the other hand, the digital input data (computer models) is a very appropriate initial material to be used for hypermedia development. The experiment is to analyse the specific of the following: the self-influence of the group on the individual work ‘qualification’, mutual influence of the team members on their own work interpretation, the influence of the digital non-linear environment on the final outcome definition. The added value of hypertext in architectural groupwork digital performance shall be examined and described. A new value of individualised, though group based, non-linearity of expression will be presented and concluded.

title	Modelling of User Activities in Building Design
source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 67-72
doi	https://doi.org/10.52842/conf.ecaade.2001.067
summary	Architects manage not only information about the building but also about the user organisation. Therefore, information systems for architectural design must be able to handle both building and organisational data. The paper describes architectural design as a creative problem solving process, and presents a recently developed prototype application for user activity modelling built as an add-on to ArchiCAD.

title	Cognitive Biases - The case of tropical architecture
source	Delft University of Technology
summary	This dissertation investigates, i) How cognitive biases (or illusions) may lead to errors in design thinking, ii) Why architects use architectural precedents as heuristics despite such possible errors, and iii) Develops a design tool that can overcome this type of errors through the introduction of a rebuttal mechanism. The mechanism controls biases and improves accuracy in architectural thinking. // The research method applied is interdisciplinary. It employs knowledge from cognitive science, environmental engineering, and architectural theory. The case study approach is also used. The investigation is made in the case of tropical architecture. The investigation of architectural biases draws from work by A. Tversky and D. Kahneman in 1982 on “Heuristics and biases”. According to Tversky and Kahneman, the use of heuristics of representativeness (based on similarity) and availability (based on ease of recall and imaginability) for judgement of probability can result in cognitive biases of illusions of validity and biases due to imaginability respectively. This theory can be used analogically to understand how errors arise in the judgement of environmental behaviour anticipated from various spatial configurations, leading to designs with dysfunctional performances when built. Incomplete information, limited time, and human mental resources make design thinking in practice difficult and impossible to solve. It is not possible to analyse all possible alternative solutions, multiple contingencies, and multiple conflicting demands, as doing so will lead to combinatorial explosion. One of the ways to cope with the difficult design problem is to use precedents as heuristic devices, as shortcuts in design thinking, and at the risk of errors. This is done with analogical, pre-parametric, and qualitative means of thinking, without quantitative calculations. Heuristics can be efficient and reasonably effective, but may not always be good enough or even correct, because they can have associated cognitive biases that lead to errors. Several debiasing strategies are discussed, and one possibility is to introduce a rebuttal mechanism to refocus the designer’s thinking on the negative and opposite outcomes in his judgements, in order to debias these illusions. The research is carried out within the framework of design theory developed by the Design Knowledge System Research Centre, TUDelft. This strategy is tested with an experiment. The results show that the introduction of a rebuttal mechanism can debias and improve design judgements substantially in environmental control. The tool developed has possible applications in design practice and education, and in particular, in the designing of sustainable environments.

title	The Combination of Design Media and Design Creativity _ Conventional and Digital Media
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007

summary	Creativity is always interested in many fields, in particular, creativity and design creativity have many interpretations (Boden, 1991; Gero and Maher, 1992, 1993; Kim, 1990; Sternberg, 1988; Weisberg, 1986). In early conceptual design process, designers used large number of sketches and drawings (Purcell and Gero, 1998). The sketch can inspire the designer to increase the creativity of the designer’s creations(Schenk, 1991; Goldschmidt, 1994; Suwa and Tversky, 1997). The freehand sketches by conventional media have been believed to play important roles in processes of the creative design thinking(Goldschmidt, 1991; Schon and Wiggins, 1992; Goel, 1995; Suwa et al., 2000; Verstijnen et al., 1998; Elsas van and Vergeest, 1998). Recently, there are many researches on inspiration of the design creativity by digital media(Liu, 2001; Sasada, 1999). The digital media have been used to apply the creative activities and that caused the occurrenssce of unexpected discovery in early design processes(Gero and Maher, 1993; Mitchell, 1993; Schmitt, 1994; Gero, 1996, 2000; Coyne and Subrahmanian, 1993; Boden, 1998; Huang, 2001; Chen, 2001; Manolya et al. 1998; Verstijinen et al., 1998; Lynn, 2001). In addition, there are many applications by combination of conventional and digital media in the sketches conceptual process. However, previous works only discussed that the individual media were related to the design creativity. The cognitive research about the application of conceptual sketches design by integrating both conventional and digital media simultaneously is absent.

title	Object-Oriented Application Development in CAD
source	Technical Report 48-01-01. Pittsburgh, PA: Carnegie Mellon University, Institute of Complex Engineered Systems
summary	This report describes a graduate interdisciplinary course offered to students in the graduate program of the School of Architecture at Carnegie Mellon and related departments in fall 2000. The motivation was the realization that when commercial CAD (Computer-Aided Design) systems recently switched from procedural application programming languages to object-oriented ones, third-party application must undergo a significant cognitive retooling"; i. e. they must know more than the syntax and semantics of the new programming language to be used and must be able to employ appropriate software development strategies that are appropriate for the new paradigm. especially with respect to the importance of modeling, a distinguishing characteristic of object-oriented programming. The goal of the course was (a) to introduce and test strategies of object-oriented application development in general and in the context of MicroStation, a state-of-the-art commercial CAD package; (b) to develop-as a course team project-an interesting application that gives students practice with these strategies and team work; and (c) to document our approach and findings so that others can learn from them. The strategies introduced were the use-case approach of Jacobson et al. and the complementary object-modeling tools of Rumbaugh that were recently integrated into the Unified Modeling Language UML. The software platform supporting the course comprised MicroStation, JMDL (a superset of Java) and ProjectBank on the CAD side and RationalRose on the modeling side. The application developed by students in the course supports the generation of drawings for remodeling projects from a set of dgn files describing the existing state of the building to be remodeled. The course was supported by a grant and in-kind contributions from Bentley with matching funds from the Pennsylvania Infrastructure Technology Alliance (PITA)."

title	Working Memory: A Mental Space for Design and Discovery
source	J. S. Gero, B. Tversky and T. Purcell (eds), 2001, Visual and Spatial Reasoning in Design, II - Key Centre of Design Computing and Cognition, University of Sydney, Australia
summary	The design process can be viewed as the product of human creativethinking; the skills of generating new knowledge from old within theexternal constraints of the items to be designed. Expert designers have highlevel skills that assist them in this process. However design effectivenessand the training of design skills could benefit from an understanding of howhuman cognition undertakes the process of creative thinking without suchspecialist training, and what aspects of human cognition impede or enhancethis process. In this paper, I shall discuss some of the empirical researchand theoretical developments that have contributed to an understanding ofon-line visual and spatial cognition that might support creative thinking.The paper starts with a discussion of a particular theoretical frameworkreferred to as working memory, and some of the empirical work that hasused this framework to explore visual and spatial cognitive functions. Thisdiscussion will set the background of the general thesis for the chapter thatvisual and spatial aspects of working memory might play important roles increative thinking and design. This will lead to a discussion of the ways inwhich human working memory and the use of external aids to thinkingmight facilitate or constrain aspects of the creative process. The paper willend with a discussion of why human beings might have developed a workingmemory system, with the possibility that its primary purpose is to supportthe process of generating new knowledge.

title	Digital Architecture in CAD studio and Internet-based competition
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	Architectural design has been changing because of the vast and creative use of computer in different ways. From the viewpoint of designing itself, computer has been used as drawing tools in the latter phase of design (Mitchell 1977; Coyne et al. 1990), presentation and simulation tools in the middle phase (Liu and Bai 2000), and even critical media which triggers creative thinking in the very early phase (Maher et al. 2000; Liu 1999; Won 1999). All the various roles that computer can play have been adopted in a number of professional design corporations and so-called computer-aided design (CAD) studio in schools worldwide (Kvan 1997, 2000; Cheng 1998). The processes and outcomes of design have been continuously developing to capture the movement of the computer age. However, from the viewpoint of social-cultural theories of architecture, the evolvement of design cannot be achieved solely by designers or design processes. Any new idea of design can be accepted socially, culturally and historically only under one condition: The design outcomes could be reviewed and appreciated by critics in the field at the time of its production (Csikszentmihalyi 1986, 1988; Schon and Wiggins 1992; Liu 2000). In other words, aspects of design production (by designers in different design processes) are as critical as those of design appreciation (by critics in different review processes) in the observation of the future trends of architecture.Nevertheless, in the field of architectural design with computer and Internet, that is, so-called computer-aided design computer-mediated design, or internet-based design, most existing studies pay more attentions to producing design in design processes as mentioned above. Relatively few studies focus on how critics act and how they interact with designers in the review processes. Therefore, this study intends to investigate some evolving phenomena of the interaction between design production and appreciation in the environment of computer and Internet.This paper takes a CAD studio and an Internet-based competition as examples. The CAD studio includes 7 master's students and 2 critics, all from the same countries. The Internet-based competition, held in year 2000, includes 206 designers from 43 counties and 26 critics from 11 countries. 3 students and the 2 critics in the CAD studio are the competition participating designers and critics respectively. The methodological steps are as follows: 1. A qualitative analysis: observation and interview of the 3 participants and 2 reviewers who join both the CAD studio and the competition. The 4 analytical criteria are the kinds of presenting media, the kinds of supportive media (such as verbal and gesture/facial data), stages of the review processes, and interaction between the designer and critics. The behavioral data are acquired by recording the design presentation and dialogue within 3 months. 2. A quantitative analysis: statistical analysis of the detailed reviewing data in the CAD studio and the competition. The four 4 analytical factors are the reviewing time, the number of reviewing of the same project, the comparison between different projects, and grades/comments. 3. Both the qualitative and quantitative data are cross analyzed and discussed, based on the theories of design thinking, design production/appreciation, and the appreciative system (Goodman 1978, 1984).The result of this study indicates that the interaction between design production and appreciation during the review processes could differ significantly. The review processes could be either linear or cyclic due to the influences from the kinds of media, the environmental discrepancies between studio and Internet, as well as cognitive thinking/memory capacity. The design production and appreciation seem to be more linear in CAD studio whereas more cyclic in the Internet environment. This distinction coincides with the complementary observations of designing as a linear process (Jones 1970; Simon 1981) or a cyclic movement (Schon and Wiggins 1992). Some phenomena during the two processes are also illustrated in detail in this paper.This study is merely a starting point of the research in design production and appreciation in the computer and network age. The future direction of investigation is to establish a theoretical model for the interaction between design production and appreciation based on current findings. The model is expected to conduct using revised protocol analysis and interviews. The other future research is to explore how design computing creativity emerge from the process of producing and appreciating.

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

title	Using a Spatial Microsimulation Decision Support System for Policy Scenario Analysis
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 1-4020-2408-8, p. 177-191
summary	This paper discusses the potential of a spatial microsimulation-based decision support system for policy analysis. The system can be used to describe current conditions and issues in neighbourhoods, predict future trends in the composition and health of neighbourhoods and conduct modelling and predictive analysis to measure the likely impact of policy interventions at the local level. A large dynamic spatial micro-simulation model is being constructed for the population of Leeds (approximately 715,000 individuals) based on spatial microsimulation techniques in conjunction with a range of data, including 2001 Census data for Output Areas and sample data from the British Household Panel Survey. The project has three main aims as follows: (i) to develop a static microsimulation model to describe current conditions in Leeds; (ii) to enable the performance of ‘What if?’ analysis on a range of policy scenarios; and (iii) to develop a dynamic microsimulation model to predict future conditions in Leeds under different policy scenarios. The paper reports progress in meeting the above aims and outlines the associated difficulties and data issues. One of the significant advantages of the spatial microsimulation approach adopted by this project is that it enables the user to query any combination of variables that is deemed desirable for policy analysis. The paper will illustrate the software tool being developed in the context of this project that is capable of carrying out queries of this type and of mapping their results. The decision support tool is being developed to support policy-makers concerned with urban regeneration and neighbourhood renewal.

title	Adaptive hypermedia
source	User modelling and User-Adapted Interaction, volume 11, pp. 87-110, Kluwer
summary	Hypertext/hypermedia systems and user-model-based adaptive systems in the areas of learning and information retrieval have for a long time been considered as two mutually exclusive approaches to information access. Adaptive systems tailor information to the user and may guide the user in the information space to present the most relevant material, taking into account a model of the user's goals, interests and preferences. Hypermedia systems, on the other hand, are `user neutral': they provide the user with the tools and the freedom to explore an information space by browsing through a complex network of information nodes. Adaptive hypertext and hypermedia systems attempt to bridge the gap between these two approaches. Adaptation of hypermedia systems to each individual user is increasingly needed. With the growing size, complexity and heterogeneity of current hypermedia systems, such as the World Wide Web, it becomes virtually impossible to impose guidelines on authors concerning the overall organization of hypermedia information. The networks therefore become so complex and unstructured that the existing navigational tools are no longer powerful enough to provide orientation on where to search for the needed information. It is also not possible to identify appropriate pre-defined paths or subnets for users with certain goals and knowledge backgrounds since the user community of hypermedia systems is usually quite inhomogeneous. This is particularly true for Web-based applications which are expected to be used by a much greater variety of users than any earlier standalone application. A possible remedy for the negative effects of the traditional `one-size-fits-all' approach in the development of hypermedia systems is to equip them with the ability to adapt to the needs of their individual users. A possible way of achieving adaptivity is by modeling the users and tailoring the system's interactions to their goals, tasks and interests. In this sense, the notion of adaptive hypertext/hypermedia comes naturally to denote a hypertext or hypermedia system which reflects some features of the user and/or characteristics of his system usage in a user model, and utilizes this model in order to adapt various behavioral aspects of the system to the user. This book is the first comprehensive publication on adaptive hypertext and hypermedia. It is oriented towards researchers and practitioners in the fields of hypertext and hypermedia, information systems, andpersonalized systems. It is also an important resource for the numerous developers of Web-based applications. The design decisions, adaptation methods, and experience presented in this book are a unique source of ideas and techniques for developing more usable and more intelligent Web-based systems suitable for a great variety of users. The practitioners will find it important that many of the adaptation techniques presented in this book have proved to be efficient and are ready to be used in various applications.

title	Interactive 3D reconstruction for urban areas. An image based tool
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 753-765
summary	Urban applications (for example arrangement, new buildings, virtual sightseeing and walkthrough) require a three dimensional (3D) geometrical model of town areas. However, most of them do not need an accurate model of reality. Such model would occupy a considerable memory space and would be too slow to handle. Architects, urban designers and civil engineers can find in our tool a medium to conceive their projects. Some types of software exist but they do not correspond exactly to our needs. Consequently we have conceived and developed an interactive tool for virtual 3D rough reconstruction of buildings. The software development has been performed in the Maya environment (ALIAS Wavefront) with C++ language and MEL (Maya Embedded Language). A constraint we set for ourselves was the use of only light devices (for easy transportation) at low price (everybody can buy such devices). The principle is to overlay on the scanned photograph of the area we want to deal with, the two dimensional (2D) cadastral plan displayed from the same viewpoint as the picture. Then each building body can be extruded from its ground polygon and the roof can be created from what the user sees on the picture. A constraint is the flatness of the polygonal surfaces. Our application context was the town of Nancy in France for which some areas have been reconstructed. Some pictures have been used as textures for polygonal surfaces, giving more reality effect to the simulation.

title	A CREATIVE CURRICULUM: PUTTING TECHNOLOGY IN ITS PLACE
source	SIGraDi biobio2001 - [Proceedings of the 5th Iberoamerican Congress of Digital Graphics / ISBN 956-7813-12-4] Concepcion (Chile) 21-23 november 2001, pp. 218-220
summary	The accessibility of 3D Modelling software presents challenges in the delivery of education aimed at developing creativity. Despite opening up innovative avenues of artistic possibility, computer technologies are essentially two-dimensional, hard to master and may restrict creativity itself. This paper describes a curriculum designed to develop creativity within an Electronic Arts programme. A student-centred, experiential learning approach was taken, which challenged students to set personal objectives within set project constraints. Formal critique sessions allowed students to develop a critical perspective. Conclusions are drawn as to the applicability of the approach to other non-artistic areas.

title	Evaluating Office Buildings with MOLCA(Model for Office Life Cycle Assessment)
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	MOLCA (Model for Office Life Cycle Assessment) is a project that aims to develop a tool that enables designers and builders to evaluate the environmental impact of their designs (of office buildings) from a environmental point of view. The model used is based on guidelinesgiven by ISO 14000, using the so-called Life Cycle Assessment (LCA) method. The MOLCA project started in 1997 and will be finished in 2001 resulting in the aforementioned tool. MOLCA is a module within broader research conducted at the Eindhoven University of Technology aiming to reduce design risks to a minimum in the early design stages.Since the MOLCA project started two major case-studies have been carried out. One into the difference in environmental load caused by using concrete and steel roof systems respectively and the role of recycling. The second study focused on biases in LCA data and how to handle them. For the simulations a computer-model named SimaPro was used, using the world-wide accepted method developed by CML (Centre for the Environment, Leiden, the Netherlands). With this model different life-cycle scenarios were studied and evaluated. Based on those two case studies and a third one into an office area, a first model has been developed.Bottle-neck in this field of study is estimating average recycling and re-use percentages of the total flow of material waste in the building sector and collecting reliable process data. Another problem within LCA studies is estimating the reliability of the input data and modelling uncertainties. All these topics will be subject of further analysis.

summary	To model a database that stores geo-indexed data or space, a diversity of models exists in the literature. In this article the models will be studied proposed by Michael F. Worboys, Peter Milne and S. A. Roberts and will be represented using OMT (Object Modelling Technique) of Rumbaugh. The models will be evaluated following a methodology based on the existence of a ideal model of reference against the one which to be able to contrast them. The created ideal pattern will be constituted in a new model for the design of space databases OxO.

title	VR Sketchpad. Create Instant 3D Worlds by Sketching on a Transparent Window
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 161-172
summary	This paper describes VR Sketchpad, a pen-based computing environment for inputting and locating 3D objects in a virtual world. Designer can use the transparency layers to quickly trace and extract any image underlay from other application software. The 3D scene generation has three levels of complexity: simple extrusion of any drawn lines of shapes (i.e., straight or curved wall and column extrusion), solid modelling from a given geometric object representation (spheres, cones and boxes), and complex configuration with objects from graphics library (furniture layout).

title	Activity objects in CAD-programs for building design. A prototype program implementation
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 61-74
summary	In the early stages of the building design process, during the programming and the proposal stages, both user activities and the building are in focus for the designer. In spite of this, today’s CAD programs give no support for management of information about user activities in the building. This paper discusses the requirements on modelling user activities in the context of building design and presents a prototype software. The prototype is developed as an add-on to the architectural design software ArchiCAD.

title	VRGLASGOW.CO.UK implementation of internet multi-user functionality to Glasgow's virtual city
source	Stellingwerff, Martijn and Verbeke, Johan (Eds.), ACCOLADE - Architecture, Collaboration, Design. Delft University Press (DUP Science) / ISBN 90-407-2216-1 / The Netherlands, pp. 135-142 [Book ordering info: m.c.stellingwerff@bk.tudelft.nl]
summary	The development of the Virtual Reality Modelling Language (VRML) for the Internet has resulted in the emergence of a multiplicity of 3D web sites. The metaphor used by these sites varies enormously from virtual galleries to virtual cities and style varies from abstract to reality. Additionally these worlds are populated by virtual objects, some having reactive or interactive properties, including movement, audio, video, databases, artificial intelligence etc. Perhaps the most stimulating embodiment of these new environments are those that offer the participant the opportunity to meet and communicate with other visitors exploring the same virtual space/world. The Glasgow Directory is an established 3D web space, with around 10,000 visitors per year. The model represents approximayely 10,000 properties in the city and is populated by contextual information on its culture and socio-economic topography. This paper will describe the background to this VR space, and suggest a set of design criteria for successfully deploying multi-user software within this and similar environments. These criteria will take into account lessons learned by 'observing' and analysing how participants interact with the existing system under different conditions and also what benefits they perceive on entering the environment via the multi-user interface. These recommendations will hopefully be applicable to a wide spectrum of internet virtual environment builders and users.
