title	Towards a Multi-Agent System for Network Decision Analysis
doi	https://doi.org/10.52842/conf.caadria.1999.373
source	CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 373-382
summary	We introduce the outline of a multi-agent system that can be used for network decision analysis. This system is based on cellular automata and multi-agent technology. The system simulates how agents move around in a particular 3D (or 2D) environment, in which space is represented as a lattice of cells. Agents represent objects or people with their own behavior, moving over the network. We think that the system provides a potentially valuable tool to support design and decision-making processes, related to user behavior, in architecture and urban planning.

title	The Use of New Media Tools n Environmental Simulation
source	Simulation of Architectural Space - Color and Light, Methods and Effects [Proceedings of the 4rd European Architectural Endoscopy Association Conference / ISBN 3-86005-267-5] Dresden (Germany), 29 September - 1 October 1999, pp. 28-31
summary	We propose a new application in environmental simulation using digital techniques and new media tools, namely QuickTimeVirtualReality (QTVR) and QuickTimeMovies (QTMovies). QTVR enables the user to interactively rotate in a 360degree panorama. The QTVR panoramas will be generated from single images taken with analogue endoscopic simulation techniques by using special QTVR software. The different QTVR panoramas of the model can be connected with each other, additionally by integrating QTMovies showing tracking shots from one panorama node to the other. Thus a virtual net from the planned urban place can be built in which the user can interactively move around and explore. Practical use of this application in public participation in urban development is proposed. A simple demoversion of the here described application will be shown at the EAEA 1999.

title	xWORLDS, the implementation of a three-dimensional collaborative sketch tool within the context of a third year design course
source	International Conference on Generative Art
summary	This work is the result of a postgraduate thesis done at the chair for Architecture and CAAD at the ETH in Zurich Switzerland. It proposes a prototype for a three-dimensional modelling tool in a networked environment. The work is composed of two distinct parts. (1) A modeling tool to create three-dimensional objects in an intuitive and interactive manner. (2) A database component to store and retrieve the objects. This modeller has been implemented for the first time in a design course, where students where using the modeller to sketch and interact within a large group to formulate aspects of their design. The Paper focuses on the modeller and on the experience from a one week workshop.1. Modelling Tool. The modeling tool operates in two different modes: (A). Composing cubic forms within a limited cubic space. (B). Deforming the composition of boxes by means of their interaction with a separate volume. For the composition of cubes, the user has to drag a cube with the mouse to continue placing cubes in space. Furthermore, he can move and delete the placed cubes. Simple and complex objects can be created this way, in an easy and intuitive manner. For the second mode, the forms are generated by intersecting a volume with an object created previously in the first mode. The volume can be scaled and moved. The part of the existing object located outside the volume remains unchanged, while the part that lies inside it is transformed in the same way as the volume. Complex forms can be created in this way with simple transformations. 2. Database Storage and Retrieval.The created objects can be stored in a database. Other users can access the objects stored in the database and continue working on them in the same modeling environment. There are two ways to interact with objects from the database. On one side it is possible to substitute the composition of cubes, and keep the distorted framestructure of the currently active object unchanged. On the other side it is possible to initiate a morphing process between the currently active framestructure and the framestructure of an object from the database. This process can be stopped at any time. It is always possible to switch back in the modeling modus and continue work on the object.3. Workshop at the the School of Design at the Hong Kong Polytechnic University.A Group of over 100 students were using the tool in a second year design course. The tool has been implemented as part of a workshop in the second half of the design studio. The workshop lasted for one week in which a collective dataset of over 1000 models has been created by the students. Afterwards, a possibility was given to the students to retrieve models from the database and to process them in different software packages or have them physically built by a 3D printer, and then continue working on the physical model.

title	CAD Interfaces to the ARROW Manufactured Product Server
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 1-11
summary	The UK national project ARROW (Advanced Reusable Reliable Objects Warehouse) provides an Internet based framework through which it is possible to identify any of a range of manufactured products meeting specific design criteria. This open framework (based upon the IAI's IFCs) provides a mechanism for users to search for products from any participating manufacturer or supplier based both on specific attributes of a product or on any of the textual descriptions of the product. The service returns the closest matching products and allows the user to navigate to related information including manufacturer, suppliers, CAD details, VR displays, installation instructions, certificates, health and safety information, promotional information, costings, etc. ARROW also provides a toolkit to enable manufacturers and suppliers to more easily map and publish their information in the format utilised by the ARROW system. As part of the ARROW project we have examined the ability to interface from a design tool through to ARROW to automatically retrieve information required by the tool. This paper describes the API developed to allow CAD and simulation tools to communicate directly with ARROW and identify appropriate manufactured information. The demonstration system enables CAD systems to identify the closest matching manufactured product to a designed product and replacing the designed product with the details supplied by the manufacturer for the manufactured product as well as pulling through product attributes utilised by the design application. This paper provides a description of the ARROW framework and issues faced in providing information based upon standards as well as containing information not currently modelled in public standards. The paper looks at issues of enabling manufacturers and suppliers to move from their current world-view of product information to a more data-rich and user accessible information repository (even though this enables a uniform comparison across a range of manufacturer's products). Finally the paper comments on the likely way forward for ARROW like systems in providing quality information to end users.

title	Evolutionary Design Tools for Mass-Customisation
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 152-156
summary	This paper describes an instance of the author’s ongoing research in the field of Generative Design. The work is based on the premise that computer-aided design (CAD) should evolve beyond its current limitation of one-way interaction, and become a dynamic, intelligent, multi-user environment that encourages creativity and actively supports the evolution of individual, mass-customised designs which exhibit common features. The understanding of fundamental shape-forming processes in nature inspires us to move beyond the existing CAD paradigms and re-examine the way we can benefit from the computers in design. We can use this knowledge to create a new generation of computer-based design tools which use evolutionary search algorithms to generate create a common family of individual designs optimised according to particular criteria, while supporting our design intuition. The author explores this idea by illustrating a research project between the Hong Kong Polytechnic University and Deakin University (Australia). The project implements a multi-user oriented design tool for evolutionary design, which was tailored to produce a simple object such as door handle. The paper first gives a short historical and philosophical to the work, then describes the technical and algorithmic requirements, and implementation of the system. It concludes by describing an experiment in which the system was used on a "live" test group of people to generate individual, mass-customised designs.

title	Río Digital (Digital Rio)
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 478-481
summary	RioDigital is a text situated on new forms of expression of knowledge over the city. It is a written multimedia whose objective is to place in disposability for the society the complexity of urban space on its multiple historical determinations, of its space, social and cultural forms. It is a research over the potentials of digital art to express the processes of constitution of social forms and constructions of urban space. The motion of works was in the sense of using this language to reconstitute and vivify the history of Rio de Janeiro city in the XX century. The city is an ensemble of symbols that encounters the language in its best form of presentation. The research identified visual documents as films, photos and maps that made possible to reconstruct processes of transformation, worked through the use of digital images technology that allows expression and turns move perceptible the transmission of this history. The digital image is certainly a possibility to represent urban reality. Through movement, illumination of image and of writing it was possible to express to process of construction and reconstruction of space building and social changes. We understand that the condition of citizen is associated with the feeling of belonging, which urban process every time move complex and difficult to understand, that new technologies can through synthesis, connectivity and interactivity expand the capacity of indivils to know the city and act positively with it. It is an intention to amplify the sense of belonging and encourage the action of transform.

title	Towards a Multi-Agent Model for Visualizing Simulated User Behavior to Support the Assessment of Design Performance
doi	https://doi.org/10.52842/conf.acadia.1999.226
source	Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 226-237
summary	We introduce the outline of a multi-agent model that can be used for visualizing simulated user behavior to support the assessment of design performance. We will consider various performance indicators of building environments, which are related to user reaction to design decisions. This system may serve as a media tool in the design process for a better understanding of what the design will look like, especially for those cases where design or planning decisions will affect the behavior of individuals. The system is based on cellular automata and multi-agent simulation technology. The system simulates how agents move around in a particular 3D (or 2D) environment, in which space is represented as a lattice of cells. Agents represent objects or people with their own behavior, moving over the network. Each agent will be located in a simulated space, based on the cellular automata grid. Each iteration of the simulation is based on a parallel update of the agents conforming local rules. Agents positioned within an environment will need sensors to perceive their local neighborhood and some means with which to affect the environment. In this way, autonomous individuals and the interaction between them can be simulated by the system. As a result, designers can use the system to assess the likely consequences of their design decisions on user behavior. We think that the system provides a potentially valuable tool to support design and decision-making processes, related to user behavior in architecture and urban planning.

title	Where the Footprints Lead: Tracking down other roles for social navigation
source	Social Navigation of Information Space, eds. A. Munro, K. H. and D Benyon. London: Springer-Verlag, pp 15-34
summary	Collaborative Filtering was proposed in the early 1990's as a means of managing access to large information spaces by capturing and exploiting aspects of the experiences of previous users of the same information. Social navigation is a more general form of this style of interaction, and with the widening scope of the Internet as an information provider, systems of this sort have rapidly moved from early research prototypes to deployed services in everyday use. On the other hand, to most of the HCI community, the term social navigation" is largely synonymous with "recommendation systems": systems that match your interests to those of others and, on that basis, provide recommendations about such things as music, books, articles and films that you might enjoy. The challenge for social navigation, as an area of research and development endeavour, is to move beyond this rather limited view of the role of social navigation; and to do this, we must try to take a broader view of both our remit and our opportunities. This chapter will revisit the original motivations, and chart something of the path that recent developments have taken. Based on reflections on the original concerns that motivated research into social navigation, it will explore some new avenues of research. In particular, it will focus on two. The first is social navigation within the framework of "awareness" provisions in collaborative systems generally; and the second is the relationship of social navigation systems to spatial models and the ideas of "space" and "place" in collaborative settings. By exploring these two ideas, two related goals can be achieved. The first is to draw attention to ways in which current research into social navigation can be made relevant to other areas of research endeavour; and the second is to re-motivate the idea of "social navigation" as a fundamental model for collaboration in information-seeking."

title	Net-Based History of Architecture
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 319-325
summary	History sequences in professional architecture programs must meet broad educational objectives. Inherent in an architect’s education is a tension between the rigorous consideration of important ideas in the history of architecture and the inspired implementation of these ideas in the design studio. A digital history course can bridge the education/training divide by making the study of history emulate the methods and strategies used in the architecture studio. Using a relational database and navigation software, we have developed a course in which students move through a digital environment of text, image, audio and video resources pertaining to broad historical categories in architecture. Charged with producing historical genealogies, students must incorporate current architectural and cultural concerns in their distillation of the history presented by the articles, surveys, manifestoes, photographs, drawings and interviews encountered online. The immersive multimedia environment uses hyperlinks as a structure, placing emphasis on the student’s role in navigation while increasing the possibilities for chance encounters in the material. The delivery of basic material having been accomplished independently by the student, class meetings are used for higher-level discussions of the issues that surface. The project is currently being implemented as a half-semester course in 20th century architecture for a small group of sophomore students in the professional Bachelor of Architecture program. The project’s pedagogical and technical aspects will be discussed with respect to this stage of its development.

title	Interdisciplinary Collaboration in the Virtual Design Studio Design Studio
source	Proceedings of the 17th Annual EAAE Annual Conference, Plymouth UK
summary	Drastic changes in technology and economics currently impact common working structures. Moreover, a fundamental move of western societies from industrial and service oriented societies to information oriented societies can be observed. Like others, the AEC industry is also exposed to the challenge of these fundamental changes, not only regarding an ever growing stock of information on building components and materials, but also because of new methods of collaboration to be applied by all participants. As a result, integrating domain specific knowledge into the design process and conversely, conveying design intentions to domain experts, is meaningful in a constantly growing scale. Utilising advanced technology, a twofold approach in research and education, undertaken at the Institut für Industrielle Bauproduktion (ifib), University of Karlsruhe, is the basis of efforts to create and develop integrating methods of collaboration into the design and planning process. In addition, the integration of AEC practitioners (investors, users, designers, engineers) in the education process provides both drastic changes in the fields of design and construction education of students and a promising approach for life long learning. The focus of this paper is to present the current state of work and to report on experiences gathered during several Virtual Design Studios (VDS) in which multi-disciplinary participants from various Universities and backgrounds were involved. Platforms for the activities are World Wide Web based applications as well as animations, VR, CAD and video conferencing.

title	Performance criteria used in fire safety design
source	Automation in Construction 8 (4) (1999) pp. 489-501
summary	In many countries around the world, building codes are shifting from prescriptive- to performance-based for technical, economic, and social reasons. This move is made possible by progress in fire safety technologies, including the development of engineering tools that are required to implement performance codes. The development of performance-based codes follows a transparent, hierarchical structure in which there are usually three levels of objectives. The top level objectives usually state the functional requirements and the lowest level the performance criteria. Usually, one middle level exists, however, more levels can be used in this hierarchical structure depending on the complexity of the requirements. The success of performance-based codes depends on the ability to establish performance criteria that will be verifiable and enforceable. The performance criteria should be such that designers can easily demonstrate, using engineering tools, that their designs meet them and that the code authority can enforce them. This paper presents the performance criteria that are currently used by fire protection engineers in designing fire safety systems in buildings. These include deterministic and probabilistic design criteria as well as safety factors. The deterministic criteria relate mainly to life safety levels, fire growth and spread levels, fire exposure and structural performance. The probabilistic criteria focus on the incident severity and incident likelihood. Finally, the inclusion of safety factors permits a conservative design and allows for a smaller margin of error due to uncertainty in the models and the input data.

source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 79-82
summary	During recent years, developments in the area of virtual reality and its applications in architecture have undergone a number of important transformations that point out the need of an updated revision and adjustment as regards its current situation status and also that which concerns its potentialities within a foreseeable future. This paper seeks to provide an ample vision about recent developments of VR in architectural applications and, also, about its potential developments within the settings provided by such imminent phenomena as the upcoming Internet II and its future impact on the three dimensional and multisensorial qualities of the information that will move within cyberspace in the next decades. The paper also comments on experiencies underway at the Laboratory of Advanced Techniques in Design, Faculty of Architecture and Urbanism, Universidad Central de Venezuela in collaboration with the Laboratory of Computer Graphics, School of Computing, also at UCV, Caracas. Finally, a number of considerations and conjectures are dedicated to the new field of VR multi-access worlds and its potential to virtual architectural modeling in the Intenet-WWW.

summary	The Digital Dialectic is an interdisciplinary jam session about our visual and intellectual cultures as the computer recodes technologies, media, and art forms. Unlike purely academic texts on new media, the book includes contributions by scholars, artists, and entrepreneurs, who combine theoretical investigations with hands-on analysis of the possibilities (and limitations) of new technology. The key concept is the digital dialectic: a method to ground the insights of theory in the constraints of practice. The essays move beyond journalistic reportage and hype into serious but accessible discussion of new technologies, new media, and new cultural forms.

title	Digitally Mediated Design: Using Computer Programming to Develop a Personal Design Process
source	Massachusetts Institute of Technology, Department of Architecture
summary	This thesis is based on the proposal that the current system of architectural design education confuses product and process. Students are assessed through, and therefore concentrate on, the former whilst the latter is left in many cases to chance. This thesis describes a new course taught by the author at MIT for the last three years whose aim is to teach the design process away from the complexities inherent in the studio system. This course draws a parallel between the design process and the Constructionist view of learning, and asserts that the design process is a constant learning activity. Therefore, learning about the design process necessarily involves learning the cognitive skills of this theoretical approach to education. These include concrete thinking and the creation of external artifacts to develop of ideas through iterative, experimental, incremental exploration. The course mimics the Constructionist model of using the computer programming environment LOGO to teach mathematics. It uses computer programming in a CAD environment, and specifically the development of a generative system, to teach the design process. The efficacy of such an approach to architectural design education has been studied using methodologies from educational research. The research design used an emergent qualitative model, employing Maykut and Morehouses interpretive descriptive approach (Maykut & Morehouse, 1994) and Glaser and Strausss Constant Comparative Method of data analysis (Glaser & Strauss, 1967). Six students joined the course in the Spring 1999 semester. The experience of these students, what and how they learned, and whether this understanding was transferred to other areas of their educational process, were studied. The findings demonstrated that computer programming in a particular pedagogical framework, can help transform the way in which students understand the process of designing. The following changes were observed in the students during the course of the year: Development of understanding of a personalized design process; move from using computer programming to solve quantifiable problems to using it to support qualitative design decisions; change in understanding of the paradigm for computers in the design process; awareness of the importance of intrapersonal and interpersonal communication skills; change in expectations of, their sense of control over, and appropriation of, the computer in the design process; evidence of transference of cognitive skills; change from a Behaviourist to a Constructionist model of learning Thesis Supervisor: William J.

title	APPLICATION OF SPATIAL DESIGN ABILITY IN A POSTGRADUATE COURSE
source	Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 75-82
summary	Spatial Design Ability (SDA) has been defined by the author (1983) as the capacity to anticipate the effects (psychological impressions) that architectural spaces or its components produce in observers or users. This concept, which requires the evaluation of spaces by the people that uses it, was proposed as a guideline to a Masters Degree Course in Architectural Design at the Universidad Autonoma de Aguascalientes in Mexico. The theory and the exercises required for the experience needed a model that could simulate spaces in terms of all the variables involved. Full-scale modeling as has been tested in previous research, offered the most effective mean to experiment with space. A simple, primitive model was designed and built: an articulated ceiling that allows variation in height and shape, and a series of wooden panels for the walls and structure. Several exercises were carried out, mainly to experience cause -effect relationships between space and the psychological impressions they produce. Students researched into spatial taxonomy, intentional sequences of space and spatial character. Results showed that students achieved the expected anticipation of space and that full-scale modeling, even with a simple model, proved to be an effective tool for this purpose. The low cost of the model and the short time it took to be built, opens an important possibility for Institutions involved in architectural studies, both as a research and as a learning tool.

summary	Several research projects (Gramazio et al. 2014; Willmann et al. 2015; Helm et al. 2017; Adel et al. 2018; Adel Ahmadian 2020) have investigated the use of automated assembly technologies (e.g., industrial robotic arms) for the fabrication of nonstandard timber structures. Building on these projects, we present a novel and transferable process for the robotic fabrication of bespoke timber subassemblies made of off-the-shelf standard timber elements. A nonstandard timber structure (Figure 2), consisting of four bespoke subassemblies: three vertical supports and a Zollinger (Allen 1999) roof structure, acts as the case study for the research and validates the feasibility of the proposed process.

summary	The so called "CAVE-interface" is a very interesting and thrilling development for architects! It supports a better illusion of space by exposing almost a 270° view of a computer model than the 60° which can be viewed on an ordinary computer screen. At the Lund University we have got the possibility to experiment with a CAVE-installation, using it in research and the education of CAAD. The technique and three experiments are discribed. The possibilities are discussed and some problems and questions are put forward.

summary	The development of a system capable of integrating a range of building design tools poses many challenges. Our framework for integrating design tools provides a structured approach, allowing individual parts to be developed independently. In this paper, we describe the overall framework and suggest a method for modeling and implementing each portion of the framework. Furthermore, we illustrate how such a system can integrate several design tools and be realized as a functional design system.

title	An approach for the interoperation of web-distributed applications with a design model
source	Automation in Construction 8 (3) (1999) pp. 291-303
summary	This paper defines the data and inference requirements for the integration of analysis applications with a product model described by a CAD/CAE application. Application input conditions often require sets of complex data that may be considered views of a product model database. We introduce a method that is compatible with the STEP and PLIB product description standards to define an intermediate model that selects, extracts, and validates views of information from a product model to serve as input for an engineering CAD/CAE application. The intermediate model framework was built and tested in a software prototype, the Internet Broker for Engineering Services (IBES). The first research case for IBES integrates applications that specify certain components, for example pumps and valves, with a CAD/CAE application. This paper therefore explores a sub-set of the general problem of integrating product data semantics between various engineering applications. The IBES integration method provides support for a general set of services that effectively assist interpretation and validate information from a product model for an engineering purpose. Such methods can enable application interoperation for the automation of typical engineering tasks, such as component specification and procurement.

title	Modelo Virtual Abierto de la Ciudad de San Juan (Open Virtual Model of the City of San Juan)
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 470-474
summary	The purpose of the present work is to virtually rebuild the city of san juan that was completely destroyed by an earthquake in 1944. From an audiovisual, multimedial approach, it tries to be a contribution to the recovering of the collective memory. Through virtual reality techniques, a three dimensional model of the city central area has been built, as it was before the earthquake. It has been achieved a multidisciplinary, open model that sums up a great deal of information and allows: 1.) From a pedagogic approach: an opened window to new ways of knowledgement transmission, through visual virtual information. The virtual rebuilt has been reconsidered as a pedagogic and communicational tool; 2.)
