title	ArTbitrariness in Music
source	International Conference on Generative Art
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	Sustaining Studio Culture: How Well Do Internet Tools Meet the Needs of Virtual Design Studios?
doi	https://doi.org/10.52842/conf.ecaade.2000.015
source	Promise and Reality: State of the Art versus State of Practice in Computing for the Design and Planning Process [18th eCAADe Conference Proceedings / ISBN 0-9523687-6-5] Weimar (Germany) 22-24 June 2000, pp. 15-22
summary	The Internet beckons seductively to students. The prospect of nearly instantaneous communication with acquaintances spread across the face of the earth is alluring. The ease with which rich graphical content can be made available to the world is stunning. The possibility of a design being seen by friends, family, and famous architects is tantalizing. Faculty are drawn by the potent synergy and learning that can be found in the opposition and cooperation of different cultural roots. It is probable that entire design studio sequences will be offered through distance-learning programs in the near future. Is that a good idea? Much has been written about "virtual design studios" in architecture schools and "virtual offices" in practice. Most offices have largely or totally abandoned drafting boards in favor of digital tools of production. Yet, regarding design, Ken Sanders, author of The Digital Architect, and Manager of Information Services at Zimmer Gunsul Frasca Partnership (ZGF), of Portland, Oregon, has written "we still make an effort to locate project teams together and always will". Production CAD work requires different kinds of interaction than design and design instruction. The experiments have been invaluable in developing strategies for use of the Internet as a component of a design studio series, but rarely depend entirely on use of the Internet for all course communications. In fact, most describe fairly isolated efforts to augment some aspect of traditional design environments using Internet tools (ftp, email, web). A few have implemented new pedagogic or collaboration paradigms (e.g., ETH’s phase(x)). This paper considers the traditional design studio in terms of formal and informal activities, characterizes the major Internet technologies with regard to the resulting interaction issues. In particular, it describes an area of informal work group communications that appears to be ill-supported with existing tools. The paper goes on to describe a web-based collaboration tool which was developed to address the need for less formal communication. The context for this development is the concept of a fully distributed collaboration environment with particular attention to questions of informal communication. Finally, it describes how the tool was deployed in an experimental "web studio" setting and student responses to use of the tool.

summary	The physical and visual nature of the interface devices and media that enable the human agent to interact with a virtual world have evolved over the past few years. In this paper we consider the different lines of development that have taken place in the refinement of these interfaces and summarise what has been learned about the appropriate nature of the interface for such interaction. In terms of the physical aspects we report on the kind of devices that have been used to enable the human agent to operate within the computer generated environment. We point out the successes and failures in the systems that have been tried out in recent years. Likewise we consider the kinds of software generated interface that have been used to represent virtual worlds. Again, we review the efficacy of the environments that have been devised; the quality of the Cyberplace. Our aim is to be able to comment on the effectiveness of the systems that have been devised from a number of points of view. We consider the physical and software-based aids for navigation; the nature of the representation of architectural worlds; strengthening “groundedness”; the inclusion of “otherness”; and reinforcement of the idea of “presence”

title	Testing the Space of the Virtual
doi	https://doi.org/10.52842/conf.acadia.2000.051
source	Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 51-61
summary	Various modes of electronically mediated communication, perception, and immersive bodily engagement, generally categorized as “virtual experiences,” have offered the designer of space a new array of spatial conditions to address. Each of these modes of virtual experience, from text-based discussion forums to immersive virtual reality environments, presents challenges to traditional assumptions about space and its inhabitation. These challenges require design theorization which extends beyond the notions of design within the electronic space (the textual description of the chat forum, the appearance of the computer generated imagery, etc.), and require a reconsideration of the entire electronic and physical apparatus of the mediating devices (the physical spaces which facilitate the interaction, the manner of their connection to the virtual spaces, etc.). In light of the lack of spatial theorization in this area, this paper presents both an experimental framework for understanding this complete space of the virtual and outlines a current research project addressing these theoretical challenges through the spatial implementation of a synthetic environment.

title	The Re-Convergence of Art and Science: A Vehicle for Creativity
doi	https://doi.org/10.52842/conf.caadria.2000.491
source	CAADRIA 2000 [Proceedings of the Fifth Conference on Computer Aided Architectural Design Research in Asia / ISBN 981-04-2491-4] Singapore 18-19 May 2000, pp. 491-500
summary	Ever-increasing complexity in product design and the need to deliver a cost-effective solution that benefits from a dynamic approach requires the employment and adoption of innovative design methods which ensure that products are of the highest quality and meet or exceed customers' expectations. According to Bronowski (1976) science and art were originally two faces of the same human creativity. However, as civilisation advances and works became specialised, the dichotomy of science and art gradually became apparent. Hence scientists and artists were born, and began to develop work that was polar opposite. The sense of beauty itself became separated from science and was confined within the field of art. This dichotomy existed through mankind's efforts in advancing civilisation to its present state. This paper briefly examines the relationship between art and science through the ages and discusses their relatively recent re-convergence. Based on this hypothesis, this paper studies the current state of the convergence between arts and sciences and examines the current relationship between the two by considering real world applications and products. The study of such products and their successes and impact they had in the marketplace due to their designs and aesthetics rather than their advanced technology that had partially failed them appears to support this argument. This text further argues that a re-convergence between art and science is currently occurring and highlights the need for accelerating this process. It is suggested that re-convergence is a result of new technologies which are adopted by practitioners that include effective visualisation and communication of ideas and concepts. Such elements are widely found today in multimedia and Virtual Environments (VEs) where such tools offer increased power and new abilities to both scientists and designers as both venture in each other's domains. This paper highlights the need for the employment of emerging computer based real-time interactive technologies that are expected to enhance the design process through real-time prototyping and visualisation, better decision-making, higher quality communication and collaboration, lessor error and reduced design cycles. Effective employment and adoption of innovative design methods that ensure products are delivered on time, and within budget, are of the highest quality and meet customer expectations are becoming of ever increasing importance. Such tools and concepts are outlined and their roles in the industries they currently serve are identified. Case studies from differing fields are also studied. It is also suggested that Virtual Reality interfaces should be used and given access to Computer Aided Design (CAD) model information and data so that users may interrogate virtual models for additional information and functionality. Adoption and appliance of such integrated technologies over the Internet and their relevance to electronic commerce is also discussed. Finally, emerging software and hardware technologies are outlined and case studies from the architecture, electronic games, and retail industries among others are discussed, the benefits are subsequently put forward to support the argument. The requirements for adopting such technologies in financial, skills required and process management terms are also considered and outlined.

title	The Importance of Virtual Environments in the Design of Electronic Games and Their Relevance to Architecture
doi	https://doi.org/10.52842/conf.ecaade.2000.181

summary	Ever increasing complexity in architectural design and the need to deliver a cost effective solution requires the employment and adoption of innovative design methods. Although technological changes have entered the field of architecture at a slower pace, the recent adoption of 3D modelling, Virtual Environment and multimedia represent significant changes in architectural design, visualisation and presentation. These now include tools for conceptualisation, design synthesis, design presentation, desktop publishing, animation, Internet and hypermedia authoring. Uddin argues that the major activities involved in the creative and dynamic process of architectural design deal with conceptualisation, visualisation and expression of alternative ideas through two-dimensional and three-dimensional model. This paper highlights the need for the employment of emerging computer based real-time interactive technologies that are expected to enhance the design process through better decision-making, higher quality communication and collaboration, error reduction, spatial awareness, interactive design and real-time visualisation.

summary	Based on a comparison between the perception of digital and real construction, the development of virtual systems and the review of additional sources, this paper states some differences between the design of virtual environments and architectural spaces. Virtual-reality technologies provide advanced capabilities to simulate real situations, and also to create digital worlds not referred to physical places, such as imaginary landscapes or environments devoted to electronic activities, like entertainment, learning or commerce. Some on-line services already use 3D-stages, resembling building halls and domestic objects, and several authors have mentioned virtual modeling as a job opportunity to architects. But it will argue in this paper that the design of those environments should consider their own digital characteristics. Besides, the use of virtual installations on networks impells a convergence with global media, like Internet or TV. Virtual environments can be a 3Devolution of communicational technologies, which have an increasing participation in culture, reaching a closer relationship to contemporary architecture.

title	Artificial Worlds, Virtual Generations
source	International Conference on Generative Art
summary	The progress in the scientific understanding/simulation of the evolution mechanisms and the first technological realizations (artificial life environments, robots, intelligent toys, self reproducing machines, agents on the web) are creating the base of a new age: the coming of the artificial beings and artificial societies. Although this aspect could seems a technological conquest, by our point of view it represent the foundation of a new step in the human evolution. The anticipation of this change is the development of a new cultural paradigm inherited from the theories of evolution and complexity: a new way to think to the culture, aesthetics and intelligence seen as emergent self-organizing qualities of a collectivity evolved along the time through genetic and language evolution. For these reasons artificial life is going to be an anticipatory and incredibly creative area for the artistic expression and imagination. In this paper we try to correlate some elements of the present research in the field of artificial life, art and technological grow up in order to trace a path of development for the creation of digital worlds where the artificial beings are able to evolve own culture, language and aesthetics and they are able to interact con the human people.Finally we report our experience in the realization of an interactive audio-visual art installation based on two connected virtual worlds realized with artificial life environments. In these worlds,the digital individuals can interact, reproduce and evolve through the mechanisms of genetic mutations. The real people can interact with the artificial individuals creating an hybrid ecosystem and generating emergent shapes, colors, sound architectures and metaphors for imaginary societies, virtual reflections of the real worlds.

title	Supporting collaborative design groups as design communities
source	Design Studies, Vol. 21, no. 2, March
summary	This paper explores computer support for unstructured collaboration. A web-based online environment used in conjunction with a graduate-level architectural studio was investigated, with special attention given to patterns of online behavior and the perceptions of those who used the environment. It was assumed that asynchronous collaborative environments like the one studied naturally alleviate certain problems like evaluation apprehension and production-blocking, but do not on their own motivate contributions to a group in an unstructured setting. It was hypothesized that open participation hinges on the development of a sense of community, which itself depends partially on environmental factors intrinsic to the support environment. The environment studied failed to promote open interaction and did not appear to sustain a strong sense of community. Environmental factors thought to have played a role include page structuring, page-naming conventions, and the spatial clustering of textbased exchanges.

summary	Linking solar positions with architecture is a traditional idea, but the use of graphical tools to control sunlight in urban surroundings or buildings is relatively recent. A three-dimensional working environment like the computer offers a new dimension to verify the relationships between the sun and the architecture. This paper shows a new way to calculate the incidence of solar energy in architectural environments using computer 3D modelling. The addition of virtual space visualisation to the analytic computation brings a new tool that simplifies the technical study of sunlight. We have developed several programs based upon the three-dimensional construction of the solar vault and the obstructing objects for a defined position. The first one draws the solar vault for a defined range of dates according to latitude, that is the basis of the energetic calculation. The second program computes the obstruction, i.e. the solar regions that are obstructed by any object. Finally, the third one, allow us to define an orientation to compute the energy that arrives to the analysed positioning. The last program returns the result of calculation in several ways: it shows the amount of energy through colours and makes a list of solar hours according to its energy.

summary	With the Web people can now view virtual threedimensional worlds and explore virtual space. Increasingly, novice users are interested in creating 3D Web sites. Virtual Reality Modeling Language gained ISO status in 1997, although it is being supplanted by the compatible Java3D API and alternative 3D Web technologies compete. Viewing VRML scenes is relatively straightforward on most hardware platforms and browsers, but currently there are only two ways to create 3D virtual scenes: One is to code the scene directly using VRML. The other is to use existing CAD and modeling software, and save the world in VRML format or convert to VRML from some other format. Both methods are time consuming, cumbersome, and have steep learning curves. Pen-based user interfaces, on the other hand, are for many an easy and intuitive method for graphics input. Not only are people familiar with the look and feel of paper and pencil, novice users also find it less intimidating to draw what they want, where they want it instead of using a complicated tool palette and pull-down menus. Architects and designers use sketches as a primary tool to generate design ideas and to explore alternatives, and numerous computer-based interfaces have played on the concept of "sketch". However, we restrict the notion of sketch to freehand drawing, which we believe helps people to think, to envision, and to recognize properties of the objects with which they are working. SKETCH employs a pen interface to create three-dimensional models, but it uses a simple language of gestures to control a three-dimensional modeler; it does not attempt to interpret freehand drawings. In contrast, our support of 3D world creation using freehand drawing depend on users’ traditional understanding of a floor plan representation. Igarashi et al. used a pen interface to drive browsing in a 3D world, by projecting the user’s marks on the ground plane in the virtual world. Our Sketch-3D project extends this approach, investigating an interface that allows direct interpretation of the drawing marks (what you draw is what you get) and serves as a rapid prototyping tool for creating 3D virtual scenes.

summary	Over the last 2 years the MSc Virtual Environments course in the Bartlett School of Graduate Studies has used a 3-dimensional on-line multi-user environment to explore the possibilities for the architectural design of virtual environments. The "Bartlett" virtual world is established as the environment where students undertake group design projects. After an initial computer based face-toface workshop, students work from terminals at home and around the university. Using avatar representations of themselves, tutors and students meet in the on-line environment. The environment is used for student group discussions and demonstrations, tutorials and as the virtual "siteÕ for their design projects. The "Bartlett" world is currently open to every internet user and so often has "visitors". These visitors often engage in discussions with the students resulting in interesting dynamics in the teaching pattern. This project has been very successful and is particularly popular with the students. Observations made over the 2 years the project has been running have resulted in interesting reflections on both the role of architectural design in virtual environments and the use of such environments to extend the pedagogical structure used in traditional studio teaching. This paper will review the educational experience gained by the project and propose the ideal software environment for further development. We are now examining similar types of environments currently on the market with a view to adapting them for use as a distance learning medium.

title	Beyond the low-hanging fruit: Information technology in architectural design past, present and future
source	W. Mitchell and J. Fernandez (eds), ACSA Technology Conference, MIT Press, Cambridge MA
summary	Today's commercial CAD software is the product of years of research that began in the 1960's and 1970's. These applications have found widespread use in the architectural marketplace; nevertheless they represent only the first fruits of research in computer aided design. New developments based on research in human-computer interaction (HCI), computer-supported collaborative work (CSCW), and virtual reality (VR) will result in a next generation of tools for architectural design. Although preliminary applications to design have been demonstrated in each of these areas, excellent opportunities remain to exploit new technologies and insights in service of better design software. In this paper we briefly examine each of these areas using examples from our own work to discuss the prospects for future research. We envision that future design technologies will develop from current and traditional conventions of practice combined with forward looking application of emerging technologies. In HCI, pen based interaction will allow architects to use the pencil again, without sacrificing the added power of computer aided design tools, and speech recognition will begin to play a role in capturing and retrieving design critique and discussion. In CSCW, a new generation of applications will address the needs of designers more closely than current general purpose meeting tools. In VR, applications are possible that use the technology not simply to provide a sense of three-dimensional presence, but that organize design information spatially, integrating it into the representation of artifacts and places.

title	DYNAMO - Dynamic Architectural Memory On-line
source	Educational Technology and Society, Vol.3, No.2, April 2000 (ISSN 1436-4522), pp. 86-95
summary	This paper describes the current status of DYNAMO, a web-based design assistant for students and professional designers in the field of architecture. The tool can be considered a Case-Based Design (CBD) system in so far that it was inspired by the view of cognition underlying CBD. The paper points out how DYNAMO incorporates this view, and at the same time extrapolates it beyond the individual. In this way, the tool attempts to embrace and profit from several kinds of interaction that are crucial for the development and renewal of design knowledge. This should result in a design tool that both feels cognitively comfortable to (student-) designers, and offers them a platform for exchanging knowledge and insights with colleagues in different contexts and at different levels of experience. In addition, the paper describes the implementation of these theoretical ideas as a working prototype, which has recently been tested by 4th year design students. Finally, DYNAMO is situated in the context of other comparable tools that have been or are being developed in the field of architectural design.

summary	The web offers both business and academic users potential benefits from on-line collaboration. Online education presents universities with a means of handling the “baby boom echo” without expanding physical campuses (Carnevale 2000). Business “extranets” allow greater coordination amongst team members on projects where the cast of players involves experts in different locations. Both involve substituting computer-mediated communications (CMC) for traditionally face-to-face communications. Over the past several years, the author has deployed several of the available CMC technologies in support of small group interaction in academic and administrative settings. These technologies include email, video conferencing, web publication, web bulletin boards, web databases, mailing lists, and hybrid web BBS/email combinations. This paper reflects on aspects of embodied human interaction and the affordances of current CMC technology, identifying opportunities for both exploitation and additional development. One important but under-supported aspect of work group behavior is workspace awareness, or peripheral monitoring. The Compadres web-based system, which was developed to support workspace awareness among distributed workgroup members, is described. These findings are relevant to those seeking to create online communities: virtual design studios, community groups, distributed governance organizations, and workgroups formed as parts of virtual offices.

summary	The VR-DIS research programme aims at the development of a Virtual Reality – Design Information System. This is a design and decision support system for collaborative design that provides a VR interface for the interaction with both the geometric representation of a design and the non-geometric information concerning the design throughout the design process. The major part of the research programme focuses on early stages of design. The programme is carried out by a large number of researchers from a variety of disciplines in the domain of construction and architecture, including architectural design, building physics, structural design, construction management, etc.Management of design information is at the core of this design and decision support system. Much effort in the development of the system has been and still is dedicated to the underlying theory for information management and its implementation in an Application Programming Interface (API) that the various modules of the system use. The theory is based on a so-called Feature-based modelling approach and is described in the PhD thesis by [first author, 1999] and in [first author et al., 2000a]. This information modelling approach provides three major capabilities: (1) it allows for extensibility of conceptual schemas, which is used to enable a designer to define new typologies to model with; (2) it supports sharing of conceptual schemas, called type-libraries; and (3) it provides a high level of flexibility that offers the designer the opportunity to easily reuse design information and to model information constructs that are not foreseen in any existing typologies. The latter aspect involves the capability to expand information entities in a model with relationships and properties that are not typologically defined but applicable to a particular design situation only; this helps the designer to represent the actual design concepts more accurately.The functional design of the information modelling system is based on a three-layered framework. In the bottom layer, the actual design data is stored in so-called Feature Instances. The middle layer defines the typologies of these instances in so-called Feature Types. The top layer is called the meta-layer because it provides the class definitions for both the Types layer and the Instances layer; both Feature Types and Feature Instances are objects of the classes defined in the top layer. This top layer ensures that types can be defined on the fly and that instances can be created from these types, as well as expanded with non-typological properties and relationships while still conforming to the information structures laid out in the meta-layer.The VR-DIS system consists of a growing number of modules for different kinds of functionality in relation with the design task. These modules access the design information through the API that implements the meta-layer of the framework. This API has previously been implemented using an Object-Oriented Database (OODB), but this implementation had a number of disadvantages. The dependency of the OODB, a commercial software library, was considered the most problematic. Not only are licenses of the OODB library rather expensive, also the fact that this library is not common technology that can easily be shared among a wide range of applications, including existing applications, reduces its suitability for a system with the aforementioned specifications. In addition, the OODB approach required a relatively large effort to implement the desired functionality. It lacked adequate support to generate unique identifications for worldwide information sources that were understandable for human interpretation. This strongly limited the capabilities of the system to share conceptual schemas.The approach that is currently being implemented for the core of the VR-DIS system is based on eXtensible Markup Language (XML). Rather than implementing the meta-layer of the framework into classes of Feature Types and Feature Instances, this level of meta-definitions is provided in a document type definition (DTD). The DTD is complemented with a set of rules that are implemented into a parser API, based on the Document Object Model (DOM). The advantages of the XML approach for the modelling framework are immediate. Type-libraries distributed through Internet are now supported through the mechanisms of namespaces and XLink. The implementation of the API is no longer dependent of a particular database system. This provides much more flexibility in the implementation of the various modules of the VR-DIS system. Being based on the (supposed to become) standard of XML the implementation is much more versatile in its future usage, specifically in a distributed, Internet-based environment.These immediate advantages of the XML approach opened the door to a wide range of applications that are and will be developed on top of the VR-DIS core. Examples of these are the VR-based 3D sketching module [VR-DIS ref., 2000]; the VR-based information-modelling tool that allows the management and manipulation of information models for design in a VR environment [VR-DIS ref., 2000]; and a design-knowledge capturing module that is now under development [first author et al., 2000a and 2000b]. The latter module aims to assist the designer in the recognition and utilisation of existing and new typologies in a design situation. The replacement of the OODB implementation of the API by the XML implementation enables these modules to use distributed Feature databases through Internet, without many changes to their own code, and without the loss of the flexibility and extensibility of conceptual schemas that are implemented as part of the API. Research in the near future will result in Internet-based applications that support designers in the utilisation of distributed libraries of product-information, design-knowledge, case-bases, etc.The paper roughly follows the outline of the abstract, starting with an introduction to the VR-DIS project, its objectives, and the developed theory of the Feature-modelling framework that forms the core of it. It briefly discusses the necessity of schema evolution, flexibility and extensibility of conceptual schemas, and how these capabilities have been addressed in the framework. The major part of the paper describes how the previously mentioned aspects of the framework are implemented in the XML-based approach, providing details on the so-called meta-layer, its definition in the DTD, and the parser rules that complement it. The impact of the XML approach on the functionality of the VR-DIS modules and the system as a whole is demonstrated by a discussion of these modules and scenarios of their usage for design tasks. The paper is concluded with an overview of future work on the sharing of Internet-based design information and design knowledge.

summary	In 1998, architecture schools in the three nation region of the upper Rhine came together to undertake a joint design studio. With the support of the Center for Entrepeneurship in Colmar, France, the schools worked on the reuse of the Kuenzer Mill situated near Herbolzheim, Germany. The students met jointly three times during the semester and then worked on the project at their home universities usng conventional methods. This project was essential to generating closer ties between the participating students, tutors and institutions and as such, the results were quite positive. So much so, that the organisers decided to repeat the exercise one year later. However, it became clear that although the students had met three times in large groups, the real success of a co-operative design studio would require mechanisms which allow far more intimate interaction among the participants, be they students, teachers or outside experts. The experiences from the Netzentwurf at the Institut für Industrielle Bauproduktion (ifib) showed the potential in a web based studio and the addition of ifib to the three nation group led to the development of the VuuA platform. The first project served to illuminate the the differences in teaching concepts among the partner institutions and their teaching staff as well as problems related to the integration of students from three countries with two languages and four different faculties: landscape architecture, interior design, architecture and urban planning. The project for the Fall of 1999 was the reuse of Fort Kléber in Wolfisheim by Strasbourg, France. The students again met on site to kick off the Semester but were also instructed to continue their cooperation and criticism using the VuuA platform.

summary	Patten and Ishii (2000) discovered that people are employing more versatile strategies for spatial distribution when using a tangible user interface (TUI) as opposed to a graphics user interface (GUI) (Patten & Ishii, 2000). Besides, the generated information outputs of conventional two-dimensional interacting screens are currently almost entirely addressing the visual and acoustic senses but lacking in other sensory stimuli - such as haptic, body equilibrium and sense of gravity. With the experiment described here, the multi-dimensionality of both the input on the interface and the output of the human interaction will be challenged. This paper aims to introduce a method to a real world versatile three-dimensional interface actuating a simulated spatial environment that substantiates the more unconventional sensory perception mentioned above. A physical prototype using an Arduino will be assembled to test the feasibility of the structure.

summary	Design space explorers are information-rich environments conceived for providing effective support for electronic design processes. A subsumption-based design space structures the partial designs in the environment by a relation of information specificity. It provides formal exploration operators for predictive, goal-directed movement in the underlying space of designs and an interaction model for open-ended exploration. This paper focusses on the forward moving operator based on incremental pi-resolution and discusses the topic of information removal through the erasure operator. It describes the possible usage of these operators and the entry points for mixed-initiative human-computer interaction in the SEED-Config explorer .
