title	Designing within Virtual Worlds
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 213-224
summary	This paper celebrates the successful outcome of a trial of an innovative multi-platform distributed design decision support system in which the shared design environment exists within the virtual world. The outcome is the result of a sustained three-year research and development effort, within an internationally recognised research group. The project set itself a number of ambitious targets within the broad spectrum of distributed design decision support, viz: • A multi-platform environment: the trial demonstrates inter-operability of different machine platforms - from a home PC to an international standard Virtual Reality Centre. • A distributed environment: the trial demonstrates the high level of understanding amongst the design team separated by time and space. • An ability to propose, discuss and agree upon, design decision from within the virtual world. Hitherto, virtual environments were viewing galleries; designers had to leave them to effect design changes in a conventional CAD package. The trial described in the paper amply demonstrates the potential to design, collaboratively and, in distributed mode, from within the virtual world. The two ideas upon which the system (known as JCAD-VR) is built are: • That all the users present in the virtual world have to be able to share the same virtual environment in a "transparent fashion"; • The user interface, instead of the traditional menu/windows based layout, is part of the virtual world itself. Any element of the interface becomes an object belonging to the 3D world and therefore it is treated as any other object. Each element of the interface can then be moved or scaled according to the user’s needs. The entire project is based on client-server architecture where every user logs into a virtual world and starts sharing design tasks with other users. The authors propose to present a video which demonstrates the positive outcome of the trials to date. More importantly, perhaps, the authors will put the achievements of the R+D into the context of past aspirations and developments in the subject area and, most importantly of all, suggest how these modest achievements will impact on the next decade of increasingly rapid R+D.

title	A NEW APPROACH TO VIRTUAL DESIGN FOR SPATIAL CONFIGURATION PROBLEMS,
source	7th IEEE International Information Visualisation Conference, London, UK, 16-17 July 2003. http://www.graphicslink.demon.co.uk/IV03/
summary	In this paper, we present a new framework for the use of Virtual Reality (VR) in engineering design for configuration applications. Traditional VR systems support the visual exploration of a design solution but do not assist the user in exploring alternative solutions based on domain knowledge. Extending previous work in the area of Intelligent Virtual Environment, we propose an intelligent configuration system based on constraint logic programming (CLP), integrated in a real-time 3D graphic environment. This type of integration facilitates the expression of design knowledge in the VE and enables the user to interactively solve and/or refine a spatial configuration problem. In the system described in this paper, the user can visually explore configurations, but his interaction with objects of the configuration problem triggers new cycles of constraint propagation from the modified configuration to produce a new compatible solution.

title	Real Teaching and Learning through Virtual Reality
source	International Journal of Architectural Computing vol. 1 - no. 1
summary	This paper addresses an articulated vision of Virtual Reality, which lends itself to design collaboration in teaching, learning and communication of architectural design ideas among students, design professionals and client bodies during the early stages of the design process. Virtual Reality (VR) has already acquired a new degree of complexity through development of network-based virtual communities and the use of avatars. A key intrinsic quality of VR technology is to support collaborative design experience. The design tools developed for this experiment are capable of creating 3D objects in a shared VR environment, thus allowing the design and its evolution to be shared.The choice of programming language (JavaTM) reflects the desire to achieve scalability and hardware independence, which in turn allows for the creation of a VR environment that can co-exist between high-end supercomputers and standard PCs. The prototype design environment was tested using PC workstations and an SGI system running in a Reality Centre.

title	Virtual environments in architecture and planning design: 4 possible approaches
source	International Journal of Design Computing
summary	Advancements in information retrieval (IR), local and wide area networks (LAN, WAN) and the Internet, human-computer interaction (HCI), and virtual reality (VR) technologies have enabled the emergence and availability of affordable real-time computer data visualisation and manipulation systems that can be deployed and interfaced to most Computer Aided Design (CAD) software systems. However, the rapid advancement and adoption of information visualisation in different areas is currently challenging VR system designers to formulate and deploy strategies and tools to effectively visualise, navigate and effectively communicate various types of information within a virtual environment (VE). A further problem relates to the fact that even within a single area or application the requirements are still diverse to the extent that different approaches and technologies still need to be employed before a satisfactory solution is reached. This paper presents four possible approaches in identifying and designing effective VR systems for architecture and planning design to allow the user to effectively communicate and share their experiences and ideas in a collaborative manner. It is also proposed that VEs should look beyond plain representations and reproductions of the real world environments that they portray and bear higher interpretation and expression values. The value of eliciting structuring and interfacing information and knowledge to a VE is also highlighted, as is the need for efficient database systems and CAD systems capable of exchanging information and data with VEs. Current efforts in prolonging the lifetime of VEs are being examined through four case studies that highlight the ever-escalating requirements that currently face VR researchers.

title	The VR-Desktop: an Accessible Approach to VR Environments in Teaching and Research
source	International Journal of Architectural Computing vol. 1 - no. 2
summary	The VR-Desktop initiative is an effort to bring key benefits of projection-based virtual reality into the mainstream of teaching and research at the Pennsylvania State University, through the deployment of comparatively low cost and easy to use virtual reality and integrated multimedia display systems within a variety of contexts. Recent experiences with design and implementation of single- and multi-screen VR systems for teaching and research are described. The systems discussed employ low cost and readily available hardware components, familiar desktop computing environments, and open-source VR development toolkits. The approach is modular and easily adaptable to various applications in research or instruction.

title	An Agent Approach to Supporting Collaborative Design in 3D Virtual Worlds
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 47-52

summary	3D Virtual worlds facilitate a level of communication and collaboration not readily available in conventional CAD systems. The integration of virtual worlds and CAD systems using a common data model can make a significant impact on synchronous collaboration and real time multi-user multi-disciplinary modification of building data. By using agents, the integration of 3D virtual worlds and CAD systems can go beyond that of passive data transfer. With sensors and effectors, each agent can interact with its environment by responding to changes in the CAD system or 3D virtual world, which can take the form of an update to the geometry, or as a recommendation to change non geometric information or to propagate changes to other parts of the design. The reasoning process for each agent can vary from a reflexive behaviour in which the agent responds directly to the sensor data to a reflective behaviour in which the agents reasons about its goals and alternatives before making a change to the environment. We demonstrate this approach using ArchiCAD and Active Worlds as the CAD system and the virtual world platform. An EDM database is used as the central repository for storing the representation of the relevant data model. A multi-agent system is developed to connect the virtual world to this database to allow active data sharing. This agent approach can be extended to the integration of other applications and data models.

title	DESIGN AGENTS IN 3D VIRTUALWORLDS
source	IJCAI03 Workshop on Cognitive Modeling of Agents and Multi-Agent Interaction, R Sun (ed), IJCAI, Acapulco, pp 92-100.
summary	Design agents are rational agents that monitor and modify elements of a designed environment. Special characteristics of design agents include the ability to reason about patterns and concepts, and the ability to act autonomously in modifying or changing the design to achieve their own goals. 3D Virtual Worlds are multi-user distributed systems that provide a designed environment and a closed world environment for studying design agents in a multiagent system. We present a model for a design agent reasoning process and a model for constructing a memory of the agent’s knowledge and interaction with a virtual world. The reasoning process includes sensation, perception, conception, hypothesizing, and planning a sequence of actions. Each agent has a constructed memory: a dynamic and changing view of the designed world that is determined by the agents sense data and reasoning. The agents construct and maintain a representation of the relevant objects in the world using a Function- Behavior-Structure formalism in order to reason about the intended and actual functions of the designed objects in the world. We have implemented this agent model by extending the Active Worlds platform so that each object in the 3D world can have agency. We illustrate the model with a door agent and a multi-agent room that reason about the use of the 3D world.

summary	Work on a methodology that attempts to deliver a dynamic urban information system for visualising city in change is presented. We have developed a Multi-tier Extensible platform for Dynamic and Interactive Urban Modelling (MEDIUM) in connection with a large-scale historical urban study programme that investigates the history of the City of Sheffield. The MEDIUM platform shows some new properties that could address the limitations observed in conventional static urban modelling. We consider that 3D virtual city models can be created along a chronological axis and the time dimension of each model segment can be registered in such a way that the 3D models of different times can be brought together under a unifying visualisation platform. This will allow a visual understanding of how a city may have evolved to develop. To date, we have applied the MEDIUM platform to real city datasets and produced examples that allow us to examine what effects of urban visualisation could be achieved through the dynamic user-centred approach.

title	An Object Server System for 3D Digital Design Collaboration

summary	Moving through and between computer generated 3D objects we experience a 'virtual world'. Virtual Worlds have created a dream-like landscape. They also have facilitated a paradigm shift for architects working with CAD tools where they now desire to “design three-dimensional spaces in an immersed way” (Strehlke and Engeli 2001). Architects are already working in computer-moderated collaborative networked organisations. A 3D Virtual World offers a different kind of collaboration. To understand how architects might design in an 'immersed way', three experiments are described. The experiments attempt to investigate how participants experience the 3D spaces within which they collaborated. In particular, the last experiment makes use of 'shared objects' in the scene. The software chosen to create these Virtual Worlds was VRML and JAVA due to their flexibility and rapid prototyping. Where VRML differs from most CAD languages is in its openness. This paper describes an object sharing client-server architecture based on a simple multi-user system providing navigation in CosmoPlayer 2.11 ported through Netscape. The Object Server System allows multiple clients, as avatars, and objects to be manipulated in a 3D Virtual World. The system updates the transforms of the objects explicitly allowing their transform values to be shared across multiple browser sessions.

title	A Procedural Model for Integrating Physical and Cyberspaces in Architecture
source	Doctoral dissertation, University of Plymouth, Plymouth, U.K
summary	This dissertation articulates opportunities offered by architectural computation, in particular the digital simulation of space known as virtual reality (VR) and its networked, social variant cyberspace. Research suggests that environments that hybridize technologies call for a conception of space as information, i.e. space is both a product of and tool for cognition. The thesis proposes a model whereby architecture can employ this concept of space in creating hybrids that integrate physical and cyberspaces.The dissertation presents important developments in architectural computation that disclose concepts and values that contrast with orthodox practice. Virtual reality and cyberspace, the foci of this inquiry, are seen to embody the more problematic aspects of these developments. They also raise a question of redundancy: If a simulation is good enough, do we still need to build? This question, raised early in the 1990's, is explored through a thought experiment - the Library Paradox - which is assessed and critiqued for its idealistic premises. Still, as technology matures and simulations become more realistic the challenge posed by VR/cyberspace to architecture only becomes more pressing. If the case for virtual idealism seems only to be strengthened by technological and cultural trends, it would seem that a virtual architecture should have been well established in the decade since its introduction.Yet a history of the virtual idealist argument discloses the many difficulties faced by virtual architects. These include differences between idealist and professional practitioners, the failure of technology to achieve its proponents' claims, and confusion over the meaning of virtual architecture among both architects and clients. However, the dissertation also cites the success of virtual architecture in other fields - Human Computer Interface design, digital games, and Computer Supported Collaborative Work - and notes that their adoption of space derives from practice within each discipline. It then proposes that the matter of VR/cyberspace be addressed from within the practice of architecture, a strategy meant to balance the theoretical/academic inclination of previous efforts in this field.The dissertation pursues an assessment that reveals latent, accepted virtualities in design methodologies, instrumentation, and the notations of architectural practices. Of special importance is a spatial database that now pervades the design and construction processes. The unity of this database, effectively a project's cyberspace, and its material counterpart is the subject of the remainder of the dissertation. Such compositions of physical and cyberspaces are herein called cybrids. The dissertation examines current technologies that cybridize architecture and information technology, and proposes their integration within cybrid wholes. The concept of cybrids is articulated in seven principles that are applied in a case study for the design for the Planetary Collegium. The project is presented and critiqued on the basis of these seven principles. The dissertation concludes with a discussion of possible effects of cybrids upon architecture and contemporary culture.

summary	DaimlerChrysler as a worldwide operating company is continuously maintaining and developing their brand architecture for the points of sale. It is one of the strategic decisions to have a 'Brand Architecture Center' at the company headquarters in Stuttgart to develop the brand architecture and engage local architects to adopt it to the local context. As a major step, a new generation of autohauses is currently developed. Many aspects have to be taken care of in this process, therefore a great number of specialists have to be involved. They are supported by Virtual Reality (VR) and Augmented Reality (AR). To integrate VR/AR into the architectural process, necessary architectural interactions have been integrated into the software

title	The Use of Virtual Reality in Urban Design: Enhancing the Image of Al-Ain City, UAE
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	This study aims at exploring the rapid growth of the use of Virtual Reality techniques in the field of Urban Design with application to the Al-Ain City. Currently, Virtual Reality and Virtual Environments are the most growing fields of information technology and have a great media attention. There is evidence to suggest that the use of such technology will enhance conceivable image of any proposed project at any urban setting for users, designers and clients. Therefore, city officials and administrators (clients) and the public (users) can reach better decisions regarding proposed projects within their towns and cities. Because of the limited time and resources, this study examines the visual quality of Downtown Al Ain, UAE, specifically, the Khalifa street (major shopping street). A basic VRmodel to the street was constructed. Modifications to the basic model were made to examine how changes in buildings’ heights and street vegetation affect the visual quality of the street. Results of this study showed that urban visualization is proving to be a valuable tool for designers and planners. Increasing the heights of buildings in the mid-street and on the edges, along with enforcing distinctive architectural styles for the proposed buildings will enhance the overall quality of the street. Furthermore, decreasing the intensity of current vegetation and tree heights will increase the imaginable quality of the street. Nevertheless, the built of a comprehend VR model needs more time, resources and facilities that were not available to this study. This model, if completed, tothe whole downtown area can be used both to identify existing problems and to quickly evaluate alternative solutions to those problems.

title	DEVELOPING A VIRTUAL REALITY-BASED METHODOLOGY FOR PEOPLE WITH DEMENTIA: A FEASIBILITY STUDY.
source	Journal of CyberPsychology and Behavior, Vol6, Number6, 2003.
summary	The aim of this study was to examine the feasibility of virtual reality (VR) technology for use by persons with dementia (PWD). Data were obtained directly from six PWD regarding their experiences with a virtual environment (VE) of a large outdoor park. A user-centered method was developed to assess: (a) presence; (b) user inputs; (c) display quality; (d) simulation fidelity; and (e) overall system usability. The extent to which PWD could perform four functional activities in the VE was also investigated (e.g., mailing a letter). In addition, physical and psychological well-being of PWD while interacting with the VE was assessed objectively by recording heart rate during the VR sessions and subjectively with discrete questionnaire items and real-time prompts. Symptom profiles associated with simulator sickness were assessed with an adapted version of the Simulator Sickness Questionnaire. The study found that PWD to some extent experienced presence; perceived that objects were realistic and moved naturally; generally felt in control of the interaction; and demonstrated little difficulty using a joystick for navigation. The study also demonstrated that VR is an appropriate medium for assessing functional behavior within the context of an ecologically valid VE. PWD did not experience any significant increase in symptoms associated with simulator sickness, or detriments to their psychological and physical well-being. These findings demonstrated that it is feasible to work in VEs with PWD.

title	An empirical approach to the experience of architectural space in VR - Exploring relations between features and affective appraisals of rectangular interiors

summary	While it is well known that the built environment influences our emotional state, it is often difficult to attribute these experiences to particular properties. In fact, a systematic investigation of the relation between physical structure and emotional experience of architecture has not yet been done. Now virtual reality simulations facilitate a completely controlled variation of spatial properties and thus allow to empirically evaluate architectural hypothesises. The aim of the presented study was to investigate which factors from a component-based description of rooms significantly correlate with cardinal dimensions of experience. In a perceptual experiment experiental qualities of 16 virtual vacant rectangular interiors were rated in eight principal categories by 16 participants using the semantic differential scaling technique. The scenes were generated by a custom made graphics tool that also automatically generated the component-based scene descriptions. The data analysis revealed several interesting correlations between scene features and rated experience: For example, a preference for ratios near to the golden section could be observed for spatial proportions, which are not directly perceivable. Altogether, a set of five independent factors (openness, two room proportions, room area and balustradeheight) appeared to be effective for widely describing the observed variance of the averaged attributed experiental qualities. Our combination of realistic virtual reality simulations and psychophysical data raising methods proved to be effective for basic architectural research. It allowed us to demonstrate quantitative relations between physical properties from a component-based description of architectural space and its emotional experience.

summary	Augmented Reality (AR), the layering of reality and virtuality, can be used as a tool in architecture in model scale as well as in 1:1 scale on site. By combining real architecture models with virtual representations like e.g. wind simulation an intensive understanding for impacts can be observed. Coupling AR with further virtual environments (AR and Virtual Reality) in one scenario makes AR a tangible interface for VR and on the other hand supports the group discussion of distributed teams.

summary	Physical influences on a city, such as noise, light, air flow, and solar energy quantities, can already be simulated on computers; however, these simulations are usually not embedded into the urban planning process. Regarding a broad field of these influences and their correlations will improve the quality of the design. The use of simulations in the sketching stage provides the possibility of reacting accordingly for the urban planner, which is essential for sustainable design. This paper describes the development of a virtual reality tool for the early urban design process, in which we realized a network connection between a software package calculating noise propagation in urban spaces and a virtual reality design environment. In this dynamic VR design tool, it is possible to experiment with simple geometric forms and objects (these objects can be added to constructions, removed, and transformed). Interactively, with each action of the planner, simulations are generated and visualized in the VR environment in real-time. The last part of the paper describes our concept, how this VR design tool should be integrated in the study of urban planning, and how we want the students to get a sense for the impact of their design on physical phenomena in an urban scale.

title	Learning From Mah Jong - Towards a Multi-Agent System that can Recognize Graphic Units
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 115-124
summary	Sketching is a major means of exploiting the first conceptual developments in architectural design. If we want to support the architect in the ideas-developing phase of design, then we need to understand the conventions of depiction and encoding in drawings. The theory of graphic units provides an extended list of such conventions that are widely used. We propose that a multi-agent system for recognition of graphic units in drawings is fruitful: agents can specialize in graphic units, a multi-agent system can deal with ambiguity through negotiation and conflict resolution, and multi-agent systems function in dynamically changing environments. We first make a multi-agent system that can do something simpler: playing Mah Jong solitary. The Mah Jong solitary system shares the following important features with a multi-agent system that can recognize graphic units: (1) specialized agents for moves; (2) negotiation between agents to establish the best move; (3) dynamically changing environment; and (4) search activity in more advanced strategies. The paper presents the theoretical basis of graphic units and multi-agents systems. The multi-agent framework and its implementation is presented. Various levels of game play are distinguished, and these are correlated to the multi-agent system. The paper shows how the findings form the basis for graphic unit recognition.

summary	The Virtual Reality Modeling Language (VRML) has allowed the expansion of resources and possibilities for architectural applications. In order to take even more advantage of VRML, we developed an application of virtual menus within VRML using Java Script as a first step to the creation of a Synthetic Environment Laboratory for architectural design. This paper briefly presents the criteria used to define the menus, the utilization of Visual Basic programming to allow the addition of said virtual menus to any file with extension *. wrl, specific examples of applicability of the menus developed, and how they were inserted in a methodological model of architectural design.
