title Supporting Collective Intelligence for Design in Virtual Worlds: A Case Study of the Lego Universe
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. 637-652.
summary Virtual worlds are multi-faceted technologies. Facets of virtual worlds include graphical simulation tools, communication, design and modelling tools, artificial intelligence, network structure, persistent object-oriented infrastructure, economy, governance and user presence and interaction. Recent studies (Merrick et al., 2010) and applications (Rosenman et al., 2006; Maher et al., 2006) have shown that the combination of design, modelling and communication tools, and artificial intelligence in virtual worlds makes them suitable platforms for supporting collaborative design, including human-human collaboration and human-computer co-creativity. Virtual worlds are also coming to be recognised as a platform for collective intelligence (Levy, 1997), a form of group intelligence that emerges from collaboration and competition among large numbers of individuals. Because of the close relationship between design, communication and virtual world technologies, there appears a strong possibility of using virtual worlds to harness collective intelligence for supporting upcoming “design challenges on a much larger scale as we become an increasingly global and technological society” (Maher et al, 2010), beyond the current support for small-scale collaborative design teams. Collaborative design is relatively well studied and is characterised by small-scale, carefully structured design teams, usually comprising design professionals with a good understanding of the design task at hand. All team members are generally motivated and have the skills required to structure the shared solution space and to complete the design task. In contrast, collective design (Maher et al, 2010) is characterised by a very large number of participants ranging from professional designers to design novices, who may need to be motivated to participate, whose contributions may not be directly utilised for design purposes, and who may need to learn some or all of the skills required to complete the task. Thus the facets of virtual worlds required to support collective design differ from those required to support collaborative design. Specifically, in addition to design, communication and artificial intelligence tools, various interpretive, mapping and educational tools together with appropriate motivational and reward systems may be required to inform, teach and motivate virtual world users to contribute and direct their inputs to desired design purposes. Many of these world facets are well understood by computer game developers, as level systems, quests or plot and achievement/reward systems. This suggests the possibility of drawing on or adapting computer gaming technologies as a basis for harnessing collective intelligence in design. Existing virtual worlds that permit open-ended design – such as Second Life and There – are not specifically game worlds as they do not have extensive level, quest and reward systems in the same way as game worlds like World of Warcraft or Ultima Online. As such, while Second Life and There demonstrate emergent design, they do not have the game-specific facets that focus users towards solving specific problems required for harnessing collective intelligence. However, a new massively multiplayer virtual world is soon to be released that combines open-ended design tools with levels, quests and achievement systems. This world is called Lego Universe (www.legouniverse.com). This paper presents technology spaces for the facets of virtual worlds that can contribute to the support of collective intelligence in design, including design and modelling tools, communication tools, artificial intelligence, level system, motivation, governance and other related facets. We discuss how these facets support the design, communication, motivational and educational requirements of collective intelligence applications. The paper concludes with a case study of Lego Universe, with reference to the technology spaces defined above. We evaluate the potential of this or similar tools to move design beyond the individual and small-scale design teams to harness large-scale collective intelligence. We also consider the types of design tasks that might best be addressed in this manner.

title Cyber(Inter)Sections: Looking into the Real Impact of The Virtual in the Architectural Profession
source Proceedings of the Symposium on Architectural Design Education: Intersecting Perspectives, Identities and Approaches. Minneapolis, MN: College of Architecture & Landscape Architecture, pp. 57-63
summary As both the skepticism and 'hype' surrounding cyberspace vanish under the weight of ever increasing power, demand, and use of information, the architectural discipline must prepare for significant changes. For cyberspace is remorselessly cutting through the dearest structures, rituals, roles, and modes of production in our profession. Yet, this section is not just a detached cut through the existing tissues of the discipline. Rather it is an inter-section, as cyberspace becomes also transformed in the act of piercing. This phenomenon is causing major transformations in at least three areas: 1. Cyberspace is substantially altering the way we produce and communicate architectural information. The arising new working environment suggests highly hybrid and networked conditions that will push the productive and educational landscape of the discipline towards increasing levels of fluidity, exchanges, diversity and change. 2. It has been argued that cyberspace-based human and human-data interactions present us with the opportunity to foster a more free marketplace of ideologies, cultures, preferences, values, and choices. Whether or not the in-progress cyberincisions have the potential to go deep enough to cure the many illnesses afflicting the body of our discipline need to be considered seriously. 3. Cyberspace is a new place or environment wherein new kinds of human activities demand unprecedented types of architectural services. Rather than being a passing fashion, these new architectural requirements are destined to grow exponentially. We need to consider the new modes of practice being created by cyberspace and the education required to prepare for them. This paper looks at these three intersecting territories showing that it is academia and not practice that is leading the profession in the incorporation of virtuality into architecture. Rafael Moneo's words come to mind. [2]

title Integrating Design Tools within a Human Collaborative Working
source The Int. Journal of Construction IT 5(2), pp. 47-73
summary This paper stresses the importance of establishing a collaborative working context as the basis for design integration. Within a virtual studio environment framework, a hybrid architecture for design tool integration is presented. Each design tool is wrapped as an autonomous service provider with its own data store; thus the project design data is physically distributed with the design tools. A global product model, which is augmented with meta-data description, is employed to provide a common vocabulary for communications and to assist the management of the distributed resources and activities. Collaboration-aware information is modelled and structured through the meta-data model and a tool model. Based on this, mechanisms for tool service coodination in varying modes are developed. It is then illustrated, through an implemented prototype system, how the integrated design tools might be used in human design work.

title A digital Procedure of Building Construction: A practical project
source AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title Physical and Digital Media Strategies For Exploring ‘Imagined’ Realities of Space, Skin and Light

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 Choosing Tools for a Virtual Community
source Creative Collaboration in Virtual Communities 1997, ed. A. Cicognani. VC'97. Sydney: Key Centre of Design Computing, Department of Architectural and Design Science, University of Sydney, 20 p.
summary This paper reports on the results of experiments carried out to identify the effects of computer-mediated communication between participants involved in a design problem. When setting up a virtual design community, choices must be made between a variety of tools, choices dictated by budget, bandwidth, ability, availability. How do you choose between the tools, which is useful and how will each affect the outcome of the design exchanges you plan? Cognitive modelling methodologies such as GOMS have been used by interface designers to capture the mechanisms of action and interaction involved in routine expert behavior. Using this technique, which breaks down an individual's behaviors into Goals, Operators, Methods, and Selection rules, it is possible to evaluate the impact of different aspects of an interface in task-specific ways. In the present study, the GOMS methodology was used to characterize the interactive behavior of knowledgeable participants as they worked on a design task under different communication-support conditions.

Pairs of participants were set a design problem and asked to solve it in face-to-face settings. The same problem was then tackled by participants in settings using two different modes of computer-supported communication: email and an electronic whiteboard. Protocols were collected and analyzed in terms of the constraints of each tool relative to the task and to each other. The GOMS methodology was used as a way to represent the collaborative design process in a way that yields information on both the productivity and performance of participants in each of the three experimental conditions. It also yielded information on the component elements of the design process, the basic cognitive building-blocks of design, thereby suggesting fundamentally new tools that might be created for interaction in virtual environments.

A further goal of the study was to explore the nature of task differences in relation to alternative platforms for communication. It was hypothesized that design processes involving significant negotiation would be less aided by computer support than straight forward design problems. The latter involve cooperative knowledge application by both participants and are therefore facilitated by information-rich forms of computer support. The former, on the other hand, requires conflict resolution and is inhibited by non face-to-face interaction. The results of this study point to the fact that the success of collaboration in virtual space is not just dependent on the nature of the tools but also on the specific nature of the collaborative task.

title Is Design Really Social
source Creative Collaboration in Virtual Communities 1997, ed. A. Cicognani. VC'97. Sydney: Key Centre of Design Computing, Department of Architectural and Design Science, University of Sydney, 8 p.
summary There are many who will readily agree with Mitchell’s assertion that “the most interesting new directions (for computer-aided design) are suggested by the growing convergence of computation and telecommunication. This allows us to treat designing not just as a technical process... but also as a social process.” [Mitchell 1995]. The assumption is that design was a social process until users of computer-aided design systems were distracted into treating it as a merely technical process. Most readers will assume that this convergence must and will lead to increased communication between design participants; that better social interaction leads to be better design. The unspoken assumption appears to be that putting the participants into an environment with maximal communication channels will result in design collaboration. The tools provided; therefore; must permit the best communication and the best social interaction. We think it essential to examine the foundations and assumptions on which software and environments are designed to support collaborative design communication. Of particular interest to us in this paper is the assumption about the “social” nature of design. Early research in computer-assisted design collaborations has jumped immediately into conclusions about communicative models which lead to high-bandwidth video connections as the preferred channel of collaboration. The unstated assumption is that computer-supported design environments are not adequate until they replicate in full the sensation of being physically present in the same space as the other participants (you are not there until you are really there). It is assumed that the real social process of design must include all the signals used to establish and facilitate face-to-face communication; including gestures; body language and all outputs of drawing (e.g. Tang [1991]). In our specification of systems for virtual design communities; are we about to fall into the same traps as drafting systems did?

title Design for network communities
source Proceedings of CHI, ACM Press, New York, pp. 210-217
summary Collaboration has long been of considerable interest in the CHI community. This paper proposes and explores the concept of network communities as a crucial part of this discussion. Network communities are a form of technology-mediated environment that foster a sense of community among users. We consider several familiar systems and describe the shared characteristics these systems have developed to deal with critical concerns of collaboration. Based on our own experience as designers and users of a variety of network communities, we extend this initial design space along three dimensions: the articulation of a persistent sense of location, the boundary tensions between real and virtual worlds, and the emergence and evolution of community.

title Understanding Shared Space for Informal Interaction among Geographically Distributed Teams
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. 41-54.
summary In a design project, much creative work is done in teams, thus requires spaces for collaborative works such as conference rooms, project rooms and chill-out areas. These spaces are designed to provide an atmosphere conducive to discussion and communication ranging from formal meetings to informal communication. According to Kraut et al (E.Kraut et al., 1990), informal communication is an important factor for the success of collaboration and is defined as “conversations take place at the time, with the participants, and about the topics at hand. It often occurs spontaneously by chance and in face-to-face manner. As shown in many research, much of good and creative ideas originate from impromptu meeting rather than in a formal meeting (Grajewski, 1993, A.Isaacs et al., 1997). Therefore, the places for informal communication are taken into account in workplace design and scattered throughout the building in order to stimulate face-to-face interaction, especially serendipitous communication among different groups across disciplines such as engineering, technology, design and so forth. Nowadays, team members of a project are not confined to people working in one location but are spread widely with geographically distributed collaborations. Being separated by long physical distance, informal interaction by chance is impossible since people are not co-located. In order to maintain the benefit of informal interaction in collaborative works, research endeavor has developed a variety ways to shorten the physical distance and bring people together in one shared space. Technologies to support informal interaction at a distance include video-based technologies, virtual reality technologies, location-based technologies and ubiquitous technologies. These technologies facilitate people to stay aware of other’s availability in distributed environment and to socialize and interact in a multi-users virtual environment. Each type of applications supports informal interaction through the employed technology characteristics. One of the conditions for promoting frequent and impromptu face-to-face communication is being co-located in one space in which the spatial settings play as catalyst to increase the likelihood for frequent encounter. Therefore, this paper analyses the degree to which sense of shared space is supported by these technical approaches. This analysis helps to identify the trade-off features of each shared space technology and its current problems. A taxonomy of shared space is introduced based on three types of shared space technologies for supporting informal interaction. These types are named as shared physical environments, collaborative virtual environments and mixed reality environments and are ordered increasingly towards the reality of sense of shared space. Based on the problem learnt from other technical approaches and the nature of informal interaction, this paper proposes physical-virtual shared space for supporting intended and opportunistic informal interaction. The shared space will be created by augmenting a 3D collaborative virtual environment (CVE) with real world scene at the virtual world side; and blending the CVE scene to the physical settings at the real world side. Given this, the two spaces are merged into one global structure. With augmented view of the real world, geographically distributed co-workers who populate the 3D CVE are facilitated to encounter and interact with their real world counterparts in a meaningful and natural manner.

title RealSpace in QuickTimes: architecture and digitization
source Rotterdam: Nai Publishers
summary Time and space, drastically compressed by the computer, have become interchangeable. Time is compressed in that once everything has been reduced to 'bits' of information, it becomes simultaneously accessible. Space is compressed in that once everything has been reduced to 'bits' of information, it can be conveyed from A to B with the speed of light. As a result of digitization, everything is in the here and now. Before very long, the whole world will be on disk. Salvation is but a modem away. The digitization process is often seen in terms of (information) technology. That is to say, one hears a lot of talk about the digital media, about computer hardware, about the modem, mobile phone, dictaphone, remote control, buzzer, data glove and the cable or satellite links in between. Besides, our heads are spinning from the progress made in the field of software, in which multimedia applications, with their integration of text, image and sound, especially attract our attention. But digitization is not just a question of technology, it also involves a cultural reorganization. The question is not just what the cultural implications of digitization will be, but also why our culture should give rise to digitization in the first place. Culture is not simply a function of technology; the reverse is surely also true. Anyone who thinks about cultural implications, is interested in the effects of the computer. And indeed, those effects are overwhelming, providing enough material for endless speculation. The digital paradigm will entail a new image of humankind and a further dilution of the notion of social perfectibility; it will create new notions of time and space, a new concept of cause and effect and of hierarchy, a different sort of public sphere, a new view of matter, and so on. In the process it will indubitably alter our environment. Offices, shopping centres, dockyards, schools, hospitals, prisons, cultural institutions, even the private domain of the home: all the familiar design types will be up for review. Fascinated, we watch how the new wave accelerates the process of social change. The most popular sport nowadays is 'surfing' - because everyone is keen to display their grasp of dirty realism. But there is another way of looking at it: under what sort of circumstances is the process of digitization actually taking place? What conditions do we provide that enable technology to exert the influence it does? This is a perspective that leaves room for individual and collective responsibility. Technology is not some inevitable process sweeping history along in a dynamics of its own. Rather, it is the result of choices we ourselves make and these choices can be debated in a way that is rarely done at present: digitization thanks to or in spite of human culture, that is the question. In addition to the distinction between culture as the cause or the effect of digitization, there are a number of other distinctions that are accentuated by the computer. The best known and most widely reported is the generation gap. It is certainly stretching things a bit to write off everybody over the age of 35, as sometimes happens, but there is no getting around the fact that for a large group of people digitization simply does not exist. Anyone who has been in the bit business for a few years can't help noticing that mum and dad are living in a different place altogether. (But they, at least, still have a sense of place!) In addition to this, it is gradually becoming clear that the age-old distinction between market and individual interests are still relevant in the digital era. On the one hand, the advance of cybernetics is determined by the laws of the marketplace which this capital-intensive industry must satisfy. Increased efficiency, labour productivity and cost-effectiveness play a leading role. The consumer market is chiefly interested in what is 'marketable': info- and edutainment. On the other hand, an increasing number of people are not prepared to wait for what the market has to offer them. They set to work on their own, appropriate networks and software programs, create their own domains in cyberspace, domains that are free from the principle whereby the computer simply reproduces the old world, only faster and better. Here it is possible to create a different world, one that has never existed before. One, in which the Other finds a place. The computer works out a new paradigm for these creative spirits. In all these distinctions, architecture plays a key role. Owing to its many-sidedness, it excludes nothing and no one in advance. It is faced with the prospect of historic changes yet it has also created the preconditions for a digital culture. It is geared to the future, but has had plenty of experience with eternity. Owing to its status as the most expensive of arts, it is bound hand and foot to the laws of the marketplace. Yet it retains its capacity to provide scope for creativity and innovation, a margin of action that is free from standardization and regulation. The aim of RealSpace in QuickTimes is to show that the discipline of designing buildings, cities and landscapes is not only a exemplary illustration of the digital era but that it also provides scope for both collective and individual activity. It is not just architecture's charter that has been changed by the computer, but also its mandate. RealSpace in QuickTimes consists of an exhibition and an essay.

title Integrating Design Tools within a Human Collaborative Working Context
source International Journal of Construction IT, Vol5, No 2, pp 35-53
summary Integrating design tools has been an important research subject. The work to be reported in this paper differs from many previous efforts in that it not only tackles tool-tool interoperation, but also does so within a human collaborative working context We suggest that design integration support should include not only tool interoperability, but also mechanisms for co-ordinate and control the tool use. We also argue that the higher-level management support should include not only formalised and automated mechanisms, but also semi-automated and even informal mechanisms for human designers to directly interact with each other. Within a collaborative working framework, we'll present a hybrid architecture for tool integration, in which the human designers and the design tools are assumed to be distributed while the management is centralised. In this approach, each design tool is wrapped as an autonomous service provider with its own data store; thus the project design data is physically distributed with the design tools. A meta-data augmented product model, which populates a central meta-data repository serving as a "map" for locating the distributed design objects, is devised to provide a common vocabulary for communications and to assist the management of the distributed resources and activities. A design object broker is used to mediate among the distributed tools, and the central meta-data repository. The reported work has been part of a collaborative design system called virtual studio environment We'll illustrate how the integrated design tools might be used in human design work within the virtual studio environment.

title Multi-sensory user interface for a virtual-reality-based computer-aided design system
source Computer-Aided Design, Vol. 29 (10) (1997) pp. 709-725
summary The generation of geometric shapes called `geometric concept designs' via the multi-sensory user interface of a virtual reality (VR) based system motivates the currentresearch. In this new VR-based system, geometric designs can be more effectively inputted into the computer in a physically intuitive way. The interaction mechanism issimilar to the way in which industrial designers sit and discuss concept design shapes across a table from each other, prior to making a final decision about the productdetails. By using different sensory modalities, such as voice, hand motions and gestures, product designers can convey design ideas through the VR-basedcomputer-aided design (CAD) system. In this scenario, the multi-sensory interface between human and computer plays a central role with respect to usability, usefulnessand accuracy. The current paper focuses on determining the requirements for the multi-sensory user interface and assessing the applications of different input and outputmechanisms in the virtual environment (VE). In order to evaluate this multi-sensory user interface, this paper formulates the typical activities in product shape design intoa set of requirements for the VR-CAD system. On the basis of these requirements, we interviewed typical CAD users about the effectiveness of using different sensoryinput and output interaction mechanisms such as visual, auditory and tactile. According to the results of these investigations, a nodal network of design activity thatdefines the multi-sensory user interface of the VR-CAD system is determined in the current research. The VR-CAD system is still being developed. However, voicecommand input, hand motion input, three-dimensional visual output and auditory output have been successfully integrated into the current system. Moreover, severalmechanical parts have been successfully created through the VR interface. Once designers use the VR-CAD system that we are currently developing, the interfacerequirements determined in the current paper may be verified or refined. The objectives of the current research are to expand the frontiers of product design and establisha new paradigm for the VR-based conceptual shape design system.

title What do we mean by intelligent buildings?
source Automation in Construction 6 (5-6) (1997) pp. 395-400
summary Various common definitions of intelligent buildings are discussed. A systems view of building design is a starting point for considering business, space and building management. An intelligent building helps an organisation to fulfil its objectives by facilitating the management of these resources and thereby increasing the effectiveness and efficiency of the organisation. At an even more fundamental level intelligent buildings can cope with social and technological change and also are adaptable to human needs.

title Towards a Taxonomy of Virtual Reality User Interfaces
source Proceedings of the International Conference on Information Visualisation (IV97), pp. 17-29
summary Virtual reality based user interfaces (VRUIs) are expected to bring about a revolution in computing. VR can potentially communicate large amounts of data in an easily understandable format. VR looks very promising, but it is still a very new interface technology for which very little application oriented knowledge is available. As a basis for such a future VRUI design theory, a taxonomy of VRUIs is required. A general model of human computer communication is formulated. This model constitutes a frame for the integration of partial taxonomies of human computer interaction that are found in the literature. The whole model constitutes a general user interface taxonomy. The field of VRUIs is described and delimited with respect to this taxonomy.

title Building a Synthetic Cognizer
source Design Computation Cognition conference 2004, MIT
summary Understanding ‘space’ as a structured and dynamic system can provide us with insight into the central concept in the architectural discourse that so far has proven to withstand theoretical framing (McLuhan 1964). The basis for this theoretical assumption is that space is not a void left by solid matter but instead an emergent quality of action and interaction between individuals and groups with a physical environment (Hillier 1996). In this way it can be described as a parallel distributed system, a self-organising entity. Extrapolating from Luhmann’s theory of social systems (Luhmann 1984), a spatial system is autonomous from its progenitors, people, but remains intangible to a human observer due to its abstract nature and therefore has to be analysed by computed entities, synthetic cognisers, with the capacity to perceive. This poster shows an attempt to use another complex system, a distributed connected algorithm based on Kohonen’s self-organising feature maps – SOM (Kohonen 1997), as a “perceptual aid” for creating geometric mappings of these spatial systems that will shed light on our understanding of space by not representing space through our usual mechanics but by constructing artificial spatial cognisers with abilities to make spatial representations of their own. This allows us to be shown novel representations that can help us to see new differences and similarities in spatial configurations.

title The V.C.net--A digital study in architecture
source Automation in Construction 6 (4) (1997) pp. 335-339
summary The V.C.net project is an Internet-based educational and communication tool for the architectural community. Its goal is to encourage students from architecture programs across the country and around the world to examine problems and collaborate in the exploration of ideas through the World Wide Web. The central concept of the project involves the creation of a simulated, vital urban environment constructed from various forms of digital data. This `virtual city' will be comprised of projects executed by students of architecture and urban design in US and abroad. Projects will be proposed for specific sites and will reflect real-world questions as they are mirrored in the virtual world. The city exists as a heuristic tool and is not intended as a copy of any existing human habitat. The ultimate goal of the project is to create a dynamic platform to study the interrelationship of various forces effecting urban development: architecture, planning, civil engineering, economics, social sciences, etc. The project originates at the School of Architecture of the University of Detroit Mercy and is intended to be truly interdisciplinary.

title Spatial Perception in Perspective Displays
source Report Human-Computer Interaction Lab, Virginia
summary Increasingly, computer displays are being used as the interface "window" between complex systems and their users. In addition, it is becoming more common to see computer interfaces represented by spatial metaphors, allowing users to apply their vast prior knowledge and experience in dealing with the three-dimensional (3D) world (Wickens, 1992). Desktop VR or window on a world (WoW), as it is sometimes called, uses a conventional computer monitor to display the virtual environment (VE). The 3D display applies perspective geometry to provide the illusion of 3D space.

title Spatium - A System for the Definition and Design of Shape Grammars
source CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 83-96
summary It is shown how Augmented Transition Networks (ATN) can be gradually programmed with shape grammar structures. This work is inspired by natural language parsing. Another major reference is the space-between or spatium assumption. An application is given with a simulation of Palladio villas. Then is shown that ATN frames can be encoded in a way that allows their use without specific knowledge of computer modeling. Connections between human and machine learning are touched on.

title Product Data Model for Interoperability in an Distributed Environment
source CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 571-589
summary This paper belongs to a suite of three interrelated papers. The two others are 'The VEGA Platform' and 'A Dynamic Product Model'. These two companion papers are also based on the VEGA project. The ESPRIT project VEGA (Virtual Enterprises using Groupware tools and distributed Architectures) has the objective to develop IT solutions enabling virtual enterprises, especially in the domain of architectural design and building engineering. VEGA shall give answers to many questions of what is needed for enabling such virtual enterprise from the IT side. The questions range from technologies for networks, communication between distributed applications, control, management of information flow to implementation and model architectures to allow distribution of information in the virtual enterprises. This paper is focused on the product model aspect of VEGA. So far modeling experts have followed a more or less centralized architecture (central or central with 4 satellites'). Is this also the architecture for the envisaged goal? What is the architecture for such a distributed model following the paradigm of modeling the , natural human' way of doing business? What is the architecture enabling most effective the filtering and translation in the communication process. Today there is some experience with 'bulk data' of the document exchange type. What is with incremental information (not data) exchange? Incremental on demand only the really needed information not a whole document. The paper is structured into three parts. First there is description of the modeling history or background. the second a vision of interoperability in an distributed environment from the users coming from architectural design and building engineering view point. Third is a description of work undertaken by the authors in previous project forming the direct basis for the VEGA model. Finally a short description of the VEGA project, especially the VEGA model architecture.
