title	The Design and Implementation of a Virtual Studio Environment
source	Proceedings of 2nd East-West Conference on Information Technology in Design, 126-137
summary	In this paper the authors describe the design and implementation of a virtual studio environment a distribute system for design collaboration across time and space. A virtual studio is defined as an electronic locale i the computer networks, containing distributed resources (both domain-specific design artifacts and generic Computer-Mediated Communication facilities) and inhabited by dispersed designers, whilst the virtual studj0 environment (VSE) refers to such a multi-user environment which supports the creation, operation and management of virtual studios. We'll particularly focus on reporting on the requirement analysis for a VS: the distributed system architecture, the design of the virtual studio model, and the implementation of the VSE server and VSE client programs. Conceptual buildingS design has been chosen as the application domain Advanced distributed computing technologies (CORBA, WWW) have been utilised for the prototyping.

title	Supporting Interaction Within Virtual Studios
source	Construction on the Information Highway (Ed Z. Turk), CIB Publication, vol 198, 109-120
summary	In this paper the author describes the development of a virtual studio environment, which is intended for supporting communications for both dispersed human designers and distributed CAD applications. By applying the metaphor of the real world design studio, a virtual studio model has been defined as an electronic locale in the computer networks, which contains distributed resources and is inhabited by dispersed designers. Virtual studio environment (VSE) has then been proposed to refer to such a multi-user environment which supports the creation, operation and management of virtual studios. A distributed implementation architecture, which loosely couples the domain resources with the VSE base system through resource agents, has been designed. Conceptual building design has been chosen as the application domain for prototyping. Several typical scenarios of interaction with VSE will be discussed. One of the prominent features of this system is that the supported interaction takes place within, instead of through or external to, the design systems.

title	Collaborative Design System with Network Technologies in Design Projects
source	CAADRIA ‘96 [Proceedings of The First Conference on Computer Aided Architectural Design Research in Asia / ISBN 9627-75-703-9] Hong Kong (Hong Kong) 25-27 April 1996, pp. 269-286
doi	https://doi.org/10.52842/conf.caadria.1996.269
summary	This paper depicts the work of the team of researchers at the Sasada Laboratory in the area of collaborative design and the integration of global area network such as the Internet in order to extend the architectural studio into cyber-space. The Sasada Laboratory is located at the University of Osaka, Faculty of Engineering, Department of Environmental engineering, Japan. The portfolio of the Laboratory is extensive and impressive. The projects which were produced by the men and women of the Laboratory range from the production of databases and computer simulation of several segments of different cities throughout the world to specific studies of architectural monuments. The work performed on the databases was varied and included simulation of past, present, and future events. These databases were often huge and very complex to build. They presented challenges that sometimes seemed impossible to overcome. Often, specialised software, and in some cases hardware, had to be designed on the "fly” for the task. In this paper, we describe the advances of our research and how our work led us to the development of hardware and software. Most importantly, it depicts the methodology of work which our lab undertook. This research led to the birth of what we call the "Open Development Environment” (ODE) and later to the networked version of ODE (NODE). The main purpose of NODE is to allow various people, usually separated by great distances, to work together on a given project and to introduce computer simulation into the working environment. Today, our laboratory is no longer limited to the physical location of our lab. Thanks to global area networks, such as the Internet, our office has been extended into the virtual space of the web. Today, we exchange ideas and collaborate on projects using the network with people that are spread over the five continents.

title	Teaching Architectural Composition Through the Medium of Virtual Reality Modelling
source	Approaches to Computer Aided Architectural Composition [ISBN 83-905377-1-0] 1996, pp. 91-102
summary	This paper describes an experimental teaching programme to enable architectural students in the early years of their undergraduate study to explore their understanding of the principles of architectural composition, by the creation and experience of architectural form and space in simple virtual reality environments. Principles of architectural composition, based upon the ordering and organisation of typological architectural elements according to established rules of composition, are introduced to the students, through the study of recognised works of architectural design theory. Virtual reality modelling is then used as a tool by the students for the testing and exploration of these theoretical concepts. Compositional exercises involving the creation and manipulation of a family of architectural elements to create form and space within a three dimensional virtual reality environment are carried out using Superscape VRT, a PC based virtual reality modelling system. The project seeks to bring intuitive and immersive computer based design techniques directly into the context of design theory teaching and studio practice, at an early stage in the architectural education process.

title	SIMULATION FOR ANALYSIS: REQUIREMENTS FROM ARCHITECTURAL DESIGN
source	Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary	Computerization has been a positive factor in the evolution of both kinds of analysis with respect to cost, availability and efficiency. Knowledge-based systems offer an appropriate implementation environment for normative analysis which can be more reliable and economical than evaluation by human experts. Perhaps more significant is the potential of interactive computer simulation where designs can be examined intuitively in full detail and at the same time by quantitative models. The advantages of this coupling are evident in the achievements of scientific visualization. Another advantage of computational systems is that the analysis can be linked to the design representation, thereby adding feedback to the conventional visualization of designs in drawing and modeling systems. Such connections are essential for the development of design guidance systems capable of reflecting consequences of partial inadequacies or changes to other aspects in a transparent and meaningful network of design constraints. The possibilities of computer simulation also extend to issues inadequately covered by normative analysis and in particular to dynamic aspects of design such as human movement and circulation. The paper reports on a framework for addressing two related problems, (a) the simulation of fire escape from buildings and (b) the simulation of human movement on stairs. In both cases we propose that current evaluation techniques and the underlying design norms are too abstract to offer a measure of design success, as testified by the number of fatal accidents in fires and on stairs. In addition, fire escape and stair climbing are characterized by great variability with respect to both the form of the possible designs and the profiles of potential users. This suggests that testing prototypical forms by typical users and publishing the results as new, improved norms is not a realistic proposition for ensuring a global solution. Instead, we should test every design individually, within its own context. The development of an affordable, readily available system for the analysis and evaluation of aspects such as fire escape and stair safety can be based on the combination of the technologies of virtual reality and motion capture. Testing of a design by a number of test people in an immersion space provides not only intuitive evaluations by actual users but also quantitative data on the cognitive and proprioceptive behaviour of the test people. These data can be compiled into profiles of virtual humans for further testing of the same or related designs.

title	The Development of a Virtual Studio Environment to Support Collaborative Building Design
source	Design, Synergy, Collaboration - selected papers from DEcon Conference
summary	This paper describes the development of a virtual studio environment to support collaborative working in the domain of building design. By applying and extending the real-world design studio model within the Internet-based distributed computing environments, the virtual studio concept has been refined as computerised settings, which integrate both the dispersed human designers and the distributed CAD applications. The hope is to achieve the similar effect as physical co-presence while providing extra advantages such as the support for automatic communication archiving and being less obtrusive than sharing a physical office. Like its real-world counterpart (which usually consists of the office, desks, file cabinets, instruments etc), such a virtual studio consists of the several major components, including a multi-user graphical user interface displaying the shared virtual workspace on each designer's workstation, distributed multimedia databases and CAD tools for processing the domain tasks, and rich human-human interaction facilities supporting a variety of communication modes. Advance distributed object computing technologies (0MG CORBA in particular) have been adopted for modelling and implementing the distributed systems, W3 (world-wide-web) technologies have also been exploited for constructing the distributed multi-media databases and an image communication kit. In contrast to the traditional CAD integration which is usually focused solely on the well-structured technical part of the product and process, the described research advocates a human-centred systems development strategy in which design is first of all taken as a process of social construction.

title	A Human-Centred Approach Towards Design Integration
source	Published in Information Representation and Delivery in Civil and Structural Engineering Design. (Ed B. Kumar ) CIVIL COMP Press, UK, 105-116
summary	Many past efforts have addressed design integration in terms of inter-operation among design tools/applications. In this paper the authors attempt to stress the social dimension of design and the role of explicit support for human level interaction during design systems integration. A humancentred approach will be proposed by taking design integration as collaborative use of design artifacts. A virtual studio environment framework will be presented as an integration vehicle to link social and technical dimensions within a human-human interaction context. A prototype virtual studio environment will be outlined, and a demonstration of using the VSE prototype presented. This will he followed by some discussion on the related research and further work.

title	Taller Virtual de Las Américas: Análisis, Síntesis y Propuesta de Desarrollo en Ambientes Multiusuarios Interactivos [America’s Virtual studio: Analysis, Synthesis and Proposal for develop an interactive multi-user environment]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 105-109
summary	As the title suggests, this paper makes an attempt to provide a factual analysis and synthesis of the activities that the Tex-Mex Virtual Design Studio, and later the Las Americas Virtual Design Studio, have been implementing since September of 1996, The objective of this attempt is to provide a framework for the formulation of a new conceptual and instrumental profile for future implementations of our virtual design studios. With such a purpose the paper outlines the importance of virtual design studios in the framework of opening design education to distance education methodologies and argues in favor of their further utilization for addressing issues of globalization in architecture and design education. This argument is followed by a quick description of current practices within the Las Americas Virtual Design Studio and sets the stage for a detailed description of how multi-user interactive environments may further support interaction within virtual design studios.

title	No More Fear or Doubt: Electronic Architecture in Architectural Education
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	Operating electronic and Internet worked tools for Architectural education is an important, and merely a prerequisite step toward creating powerful tele-collabortion and tele-research in our Architectural studios. The design studio, as physical place and pedagogical method, is the core of architectural education. The Carnegie Endowment report on architectural education, published in 1996, identified a comparably central role for studios in schools today. Advances in CAD and visualization, combined with technologies to communicate images, data, and “live” action, now enable virtual dimensions of studio experience. Students no longer need to gather at the same time and place to tackle the same design problem. Critics can comment over the network or by e-mail, and distinguished jurors can make virtual visits without being in the same room as the pin-up—if there is a pin-up (or a room). Virtual design studios (VDS) have the potential to support collaboration over competition, diversify student experiences, and redistribute the intellectual resources of architectural education across geographic and socioeconomic divisions. The challenge is to predict whether VDS will isolate students from a sense of place and materiality, or if it will provide future architects the tools to reconcile communication environments and physical space.

summary	We often speak of changes in design process due to an application of computers. But in my opinion we more often rather speak of lack of changes. Lets hope that some day we will be able to witness full integrity and compatibility of design process and tools applied in it. Quite possible such an integrity may occur in the cyberspace. Nevertheless before that could happen some changes within the teaching methods at faculties of architecture, where despite great numbers of computer equipment used, the students are still being taught as in the XIX century. In terms of achieved results it proves ineffective because application of chalk and blackboard only will always loose to new media, which allow visual perception of dinosaurs in Jurassic Park. Our civilisation is the iconographic one. And that is why teaching methods are about to change. An application of computer as simply a slide projector seems to be way too expensive. New media demands new process and new process demands new media. Lets hope that could be achieved in cyberspace as being a combination of: classic ways of teaching, hypertext, multimedia, virtual reality and a new teaching methodology (as used in Berlitz English School - full brainwash). At our faculty several years ago we experimentally undertook and applied an Integrated Design Teaching Method. A student during design process of an object simultaneously learnt all aspects and functions of the object being designing i.e.: its structure, piping and wiring, material cost and even historic evolution of its form and function. Unfortunately that concept was too extravagant as for the seventies in our reality. At present due to wide implementation of new media and tools in design process we come to consider reimplementation of IDTM again.

title	The MIT Design Studio of the Future: Virtual Design Review Video Program
source	Proceedings of ACM CSCW'96 Conference on Computer-Supported Cooperative Work 1996 p.10
summary	The MIT Design Studio of the Future is an interdisciplinary effort to focus on geographically distributed electronic design and work group collaboration issues. The physical elements of this virtual studio comprise networked computer and videoconferencing connections among electronic design studios at MIT in Civil and Environmental Engineering, Architecture and Planning, Mechanical Engineering, the Lab for Computer Science, and the Rapid Prototyping Lab, with WAN and other electronic connections to industry partners and sponsors to take advantage of non-local expertise and to introduce real design and construction and manufacturing problems into the equation. This prototype collaborative design network is known as StudioNet. The project is looking at aspects of the design process to determine how advanced technologies impact the process. The first experiment within the electronic studio setting was the "virtual design review", wherein jurors for the final design review were located in geographically distributed sites. The video captures the results of that project, as does a paper recently published in the journal Architectural Research Quarterly (Cambridge, UK; Vol. 1, No. 2; Dec. 1995).

title	Water on tap : the use of virtual reality as an educational tool
source	College of Engineering, University of Washington
summary	A study was conducted that explored Virtual Reality (VR) as an educational tool. High school students created water molecules in an immersive virtual environment. They were tested on their knowledge of atomic and molecular structure before and after their VR experience. These results were compared to the test results of students who experienced other educational media in learning the same topic. The other media differed from VR in terms of immersion and interactivity. Interactivity was found to be significant, while immersion was found to be insignificant. Issues of training, world design, assessment, hardware resolution, and student population were suggested as possible reasons for immersion's lack of significance in this study.

title	Design in virtual environments using architectural metaphor : a HIT lab gallery
source	University of Washington
summary	This thesis explores the application and limitations of architectural metaphor in the design of virtual environments. Architecture, whether physical or virtual, is the expression of a society realized as meaningful space. Physical and virtual architecture have their own constraints and context, yet both use architectural organization as a way to order forms and spaces in the environment. Both strive to create meaningful place by defining space, and both must allow the participant to develop a cognitive map to orient and navigate in the space. The lack of physics of time and space in the virtual realm requires special attention and expression of its architecture in order for the participant to cope with transitions. These issues are exemplified by the development of an on-line gallery of virtual environments. Conclusions reached by the development of this design are discussed in the context of orientation, navigation, transition, enclosure, and scale.

summary	This paper presents a teaching experience involving students and professors from various universities, in Italy and abroad, which began in 1996 and is still on going. The Virtual Studios on the Internet (VSI) have some features in common with the Teaching Studios planned for the new programme of the faculties of Architecture in Italian universities. These are the definition of a common design theme, and the participation of disciplinary teachers. The greatest difference is in the modes of collaboration, which is achieved through information and communication technologies. The chief result of this is that the various work groups in different places can work and collaborate at the same time: the computer networks provide the means to express, communicate and share the design project.

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.

source	H.J.P. Timmermans (ed.), 3rd Design and Decision Support Systems in Architecture and Urban Planning Conference, Vol I: Architecture Proceedings, pp. 13-25
summary	Conventional CAD systems have not yet proven their ability to provide support for activities which characterise the early conceptual phase of design. We propose to refer to this set of capabilities of the human designer in conventional design as, design prototyping. We define the theoretical limitations of current CAD systems for supporting design prototyping, and postulate the potential of functionally dedicated, task related, CAD modules in Virtual Reality as a means to provide a unique form of a knowledgebased, visual design support environment for design prototyping support. We are currently engaged in a research program in which we explore CAD as a medium to support early conceptual design through rapid prototyping of architectural form. Furthermore we are exploring Virtual Reality as a potential design prototyping environment in which prototypes of designs can be constructed, communicated and visually evaluated at a high level of verisimilitude. In the first phase we have built the prototype system VIDE. This system has been used for extensive internal evaluation. In the ongoing second phase we are constructing an empirical research to observe designers at work on design prototyping in the Virtual Reality environment.

summary	In April of 1995 the Internet took a step into the third dimension with the introduction of the Virtual Reality Modeling Language (VRML) as a commercial standard. Another event that month caused fewer headlines but in retrospect was just as significant. A small company from San Francisco, Worlds Incorporated, launched WorldsChat, a three dimensional environment allowing any Internet user to don a digital costume, or avatar, and travel about and converse with other people inhabiting the space. WorldsChat was appropriately modeled on a space station complete with a central hub, hallways, sliding doors, windows, and escalators to outlying pods.

title	Wayfinding in Large-Scale Virtual Worlds
source	George Washington University
summary	As important as navigation is to human performance in virtual worlds, it is an often overlooked problem in the design process. This dissertation reports an experiment intended to show that real-world wayfinding and environmental design principles are effective in designing virtual worlds which support skilled wayfinding behavior. The design principles are adapted from both the cognitive psychology literature and urban and architectural design methodologies. There are two categories of design principles; those that guide the organizational structure of the environment, and those that guide the use and presentation of maps. The study measures subject performance on a complex searching task in a number of virtual worlds with differing environmental cues. The environments are extremely large and consist of open sea, land, and ships which are used as targets for search tasks. The worlds are augmented with either a radial grid, a map, both, or neither. For each trial, the subject's viewpoint position and orientation was sampled approximately once per second. A verbal protocol with accompanying video was used to elicit information about the search strategies employed. A map drawing exercise followed each trial in order to gain insight to the subject's spatial knowledge (i.e. cognitive map) of the environment. The results show that subjects in the treatment without any additional cues were often disoriented and had extreme difficulty completing the task. The grid was shown to provide superior directional information but both treatments using the map were superior overall due to the geocentric perspective provided. Behaviors associated with each treatment indicate that the cues had a strong effect on both search performance and search strategy. The results suggest that users of large-scale virtual worlds require structure in order to effectively navigate.
