summary	Ever since the advent of computer graphics in the sixties, computer-aided architectural design (CAAD) has made a great impact in architectural education and practice. Its central role as a new media for the representation and analysis of designs will ensure that it will continue to do so. The teaching and research in CAAD in Asia have also been growing in scope and in quality. In the 21st century, the challenges of architectural education and practice in the new millennium will open up new fronts in CAAD research. This conference is an important platform to evaluate the challenge and opportunities and will enable researchers to exchange ideas and collaboration in projects with specific relevance to CADD for Asia. This compilation of 48 papers were elected through a blind review by an international panel and presented at the conference in Singapore on 18 - 19 May 2000. The chapters are organised according to the main topics covered by the conference -- Collaborative Design, Simulation, Design Education, Knowledge Representation, Design Process, Information Systems, Design Tools, Virtual Reality and Computer Media. The Collaborative Design section consists of papers which deal with Collaborative Design Process interfaces to databases, Collaborative Design System for Citizen Participation, Team Awareness in Collaboration and Computer Environment for supporting Design Collaboration. The Simulation section deals with lighting studies, colour assessment, simulation of urban growth patterns, dynamic simulations in buildings and way-finding. The Design Education section consists of papers on design pedagogy in design studios using computers, virtual studios and virtual learning.

title	Some Phenomena of Spatial Characteristics of Cyberspace
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	"Space," which has long been an important concept in architecture (Bloomer & Moore, 1977; Mitchell, 1995, 1999), has attracted interest of researchers from various academic disciplines in recent years (Agnew, 1993; Benko & Strohmayer, 1996; Chang, 1999; Foucault, 1982; Gould, 1998). Researchers from disciplines such as anthropology, geography, sociology, philosophy, and linguistics regard it as the basis of the discussion of various theories in social sciences and humanities (Chen, 1999). On the other hand, since the invention of Internet, Internet users have been experiencing a new and magic "world." According to the definitions in traditional architecture theories, "space" is generated whenever people define a finite void by some physical elements (Zevi, 1985). However, although Internet is a virtual, immense, invisible and intangible world, navigating in it, we can still sense the very presence of ourselves and others in a wonderland. This sense could be testified by our naming of Internet as Cyberspace -- an exotic kind of space. Therefore, as people nowadays rely more and more on the Internet in their daily life, and as more and more architectural scholars and designers begin to invest their efforts in the design of virtual places online (e.g., Maher, 1999; Li & Maher, 2000), we cannot help but ask whether there are indeed sensible spaces in Internet. And if yes, these spaces exist in terms of what forms and created by what ways?To join the current interdisciplinary discussion on the issue of space, and to obtain new definition as well as insightful understanding of "space", this study explores the spatial phenomena in Internet. We hope that our findings would ultimately be also useful for contemporary architectural designers and scholars in their designs in the real world.As a preliminary exploration, the main objective of this study is to discover the elements involved in the creation/construction of Internet spaces and to examine the relationship between human participants and Internet spaces. In addition, this study also attempts to investigate whether participants from different academic disciplines define or experience Internet spaces in different ways, and to find what spatial elements of Internet they emphasize the most.In order to achieve a more comprehensive understanding of the spatial phenomena in Internet and to overcome the subjectivity of the members of the research team, the research design of this study was divided into two stages. At the first stage, we conducted literature review to study existing theories of space (which are based on observations and investigations of the physical world). At the second stage of this study, we recruited 8 Internet regular users to approach this topic from different point of views, and to see whether people with different academic training would define and experience Internet spaces differently.The results of this study reveal that the relationship between human participants and Internet spaces is different from that between human participants and physical spaces. In the physical world, physical elements of space must be established first; it then begins to be regarded as a place after interaction between/among human participants or interaction between human participants and the physical environment. In contrast, in Internet, a sense of place is first created through human interactions (or activities), Internet participants then begin to sense the existence of a space. Therefore, it seems that, among the many spatial elements of Internet we found, "interaction/reciprocity" Ñ either between/among human participants or between human participants and the computer interface Ð seems to be the most crucial element.In addition, another interesting result of this study is that verbal (linguistic) elements could provoke a sense of space in a degree higher than 2D visual representation and no less than 3D visual simulations. Nevertheless, verbal and 3D visual elements seem to work in different ways in terms of cognitive behaviors: Verbal elements provoke visual imagery and other sensory perceptions by "imagining" and then excite personal experiences of space; visual elements, on the other hand, provoke and excite visual experiences of space directly by "mapping".Finally, it was found that participants with different academic training did experience and define space differently. For example, when experiencing and analyzing Internet spaces, architecture designers, the creators of the physical world, emphasize the design of circulation and orientation, while participants with linguistics training focus more on subtle language usage. Visual designers tend to analyze the graphical elements of virtual spaces based on traditional painting theories; industrial designers, on the other hand, tend to treat these spaces as industrial products, emphasizing concept of user-center and the control of the computer interface.The findings of this study seem to add new information to our understanding of virtual space. It would be interesting for future studies to investigate how this information influences architectural designers in their real-world practices in this digital age. In addition, to obtain a fuller picture of Internet space, further research is needed to study the same issue by examining more Internet participants who have no formal linguistics and graphical training.

title	A Virtual Reality Tool to Implement City Building Codes on Capitol View Preservation
doi	https://doi.org/10.52842/conf.acadia.2000.203
source	Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 203-209
summary	In urban planning, the urban environment is a very complicated system with many layers of building codes cross-referenced and interacting together to guide urban growth. Especially, if a new urban design is located in a historical area, additional restrictions will be imposed upon regular zoning regulations to maintain the area’s historical characteristics. Often, urban regulations read as text are difficult to understand. A tool that generates adequate urban information and a quick visualization of the design will ease decision-making and enhance urban design processes. The goal of this research project is to develop a virtual reality (VR) tool with high resolution, speedy computation, and a userfriendly environment. This project initiates an interactive visualization tool to enforce city-planning regulations on viewing access to the state capitol building in Des Moines, Iowa. The capitol building houses the Iowa Legislature and is a symbol of state power. Maintaining the view from surrounding areas will preserve the building’s monumental and symbolic meaning. To accomplish this, the City Community Development Department and the Capitol Planning Committee developed a Capitol View Corridor Project, which sets up seven visual corridors to prevent the view toward the capitol from being blocked by any future designs. Because city regulations are not easy for the public and designers to interpret and comprehend, this project intends to develop a VR tool to create a transparent environment for visualizing the city ordinances.

title	Base de datos de la arquitectura moderna de la ciudad de Maracaibo 1920-1990 [Database of the Modern Architecture of the City of Maracaibo 1920-1990]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
summary	Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title	Computer-aided design systems for the 21st century: some design guidelines
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	This paper proposes nine design principles for a new generation of computer-aided design (CAD) systems that actively support the decision making and problem solving activities of environmental design. Foremost among these are: a meaningful internal object-based representation of the artifact being designed within its environmental context; a collaborative problem solving paradigm in which the human designer and the computer form a complementary partnership; and, the notion of decision-support tools rather than predefined solutions. Two prototype computer-aided design systems implemented by the CAD Research Center that embody most of these concepts are described. ICADS (Intelligent Computer-Aided Design System) incorporates multiple expert agents in domains such as natural and artificial lighting, noise control, structural system selection, climatic determinants, and energy conservation. Given a particular building design context, the agents in ICADS draw upon their own expertise and several knowledgebases as they monitor the actions of the human designer and collaborate opportunistically. KOALA (Knowledge-Based Object-Agent Collaboration) builds on the multi-agent concepts embodied in ICADS by the addition of two kinds of agents. Mentor agents represent the interests of selected objects within the ontology of the design environment. In the implemented KOALA system building spaces are represented by agents capable of collaborating with each other, with domain agents for the provision of expert services, and with the human designer. Facilitator agents listen in on the communications among mentor agents to detect conflicts and moderate arguments. While both of these prototype systems are limited in scope by focussing on the earliest design stages and restricted in their understanding of the inherent complexity of a design state, they nevertheless promise a paradigm shift in computer-aided design.

title	An Analysis and Simulation of Curtain Wall Reflection Glare
doi	https://doi.org/10.52842/conf.ecaade.1999.744
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 744-750
summary	This paper presents a computer-aided visualization on the influence of reflected sunbeams from curtain wall buildings. A survey was made to local buildings and it was discovered that reflected glare is a significant urban problem. Based on survey findings, a simulation was conducted to compare with actual occurrences in order to increase the comprehension of the consequences of window orientation and angles in the design stage. The simulation enabled design evaluation with an inspection above normal eye level and in a broader area, than that which normally could be achieved in a site survey at a pedestrian's or a driver's level. The computer simulation verified the influence of reflection on the urban environment by using a time-based record. In order to provide design solutions, the simulation used a 10x10x10 cube in referencing the horizontal area that would receive reflections. Due to the symmetric shape of the cube, a butterfly shaped boundary of reflection area (BRA) was concluded. BRA is smaller on the summer solstice than on the spring or autumnal equinox. In order to reduce BRA, a passive design approach was applied by tilting or rotating walls to evaluate how the tilted angles or orientation of the façade could affect reflected glare.

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.

summary	The incorporation of computer science in architecture has been happening in an evolutionary process where we can appreciate a transition from single tools of process automation to a hybrid and heterogeneous group of methods that radically are transforming professional labor. This paper describes experiences of authors in three instances of computer science applied to the urban and architectural design developed as well the university academic environment, and in professional consulting. The document not only makes emphasis on the nature and modality of each method, but even describes the philosophical and conceptual impact that each one of them implies in teaching and to making architecture.

title	Virtual study abroad and exchange studio
source	Automation in Construction 9 (1) (2000) pp. 57-71
summary	The digital design studio has an area of application where conventional media are incapable of being used; collaboration in learning, design and dialogue with people in places other than where one lives. This distinctive opportunity has lead the authors to explore a form of design brief and virtual design studio (VDS) format not well addressed in the literature. Instead of sharing the same design brief, students in this alternative format design a project in the other students' city and do not collaborate on the same design. Collaboration with other students takes the form of teaching each other about the city and culture served by the design. The authors discovered these studios produce a focus on site context that serves our pedagogical objectives – a blend of architectural, landscape architectural and urban design knowledge. Their students use a range of commercial CAD and computer supported collaborative work (CSCW) software common to that used in many VDS experiments reported on in the literature.However, this conventional use of technology is contrasted with a second distinctive characteristic of these studios, the use of custom software tools specifically designed to support synchronous and asynchronous three-dimensional model exchange and linked attribute knowledge. The paper analyzes some of the virtual design studio (VDS) work between the Swiss Federal Institute of Technology, the University of Toronto, and the University of Melbourne. The authors articulate a framework of VDS dimensions that structures their teaching and research.

title	Sunlight Energy Graphic and Analytic Control in 3D Modelling

source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 733-738
summary	Linking solar positions with architecture is a traditional idea, but the use of graphical tools to control sunlight in urban surroundings or buildings is relatively recent. A three-dimensional working environment like the computer offers a new dimension to verify the relationships between the sun and the architecture. This paper shows a new way to calculate the incidence of solar energy in architectural environments using computer 3D modelling. The addition of virtual space visualisation to the analytic computation brings a new tool that simplifies the technical study of sunlight. We have developed several programs based upon the three-dimensional construction of the solar vault and the obstructing objects for a defined position. The first one draws the solar vault for a defined range of dates according to latitude, that is the basis of the energetic calculation. The second program computes the obstruction, i.e. the solar regions that are obstructed by any object. Finally, the third one, allow us to define an orientation to compute the energy that arrives to the analysed positioning. The last program returns the result of calculation in several ways: it shows the amount of energy through colours and makes a list of solar hours according to its energy.

title	COMPUTER-MEDIATED COMMUNICATION IN DESIGN
source	PhD Thesis, Faculty of Architecture, University of Sydney
summary	Up till now, architects collaborating with other colleagues did so mostly face-to-face (FTF). They had to be in the same space (co-located) at the same time. Communication was ‘spontaneous’ and ideas were represented, whether verbal or nonverbal, by talking and using ‘traditional drawing tools’. If they were geographically displaced, the interaction was then space affected as well as the probability of being time affected. In this case communication was usually mediated through the telephone, and graphically represented ideas were sent by Fax or posted documents. Recently, some architectural firms started using modems and Internet connections to exchange information, by transferring CAD drawings as well as design information, through e-mail and file transfer protocol (FTP). Discussing ideas in architecture, as a more abstract notion, is different from discussing other more concrete arguments using video conferencing. It is more important to ‘see’ what is being discussed at hand than ‘watch’ the other person(s) involved in the discussion. In other words the data being conveyed might be of more importance than the mode of communication. Taking into consideration recent developments in computer and communication technologies this thesis investigates different communication channels utilised in architectural collaboration through Computer Mediated Collaborative Design (CMCD) sessions as opposed to FTF sessions. This thesis investigates the possible effects these different channels have on collaborative design in general and collaborative design communication in particular. We argue that successful CMCD does not necessarily mean emulating close proximity environments. Excluding certain communication channels in a CMCD environment might affect the flow and quantity of synchronous collaborative communication, but not necessarily the quality and content of mutually communicated and represented design ideas. Therefore different communication channels might affect the type of communication and not necessarily the content of the communication. We propose that audio and video are not essential communication channels in CMCD environments. We posit that architects will collaborate and communicate design representations effectively although with some differences, since those two channels might cause interruptions and successful collaborative sessions can take place without them. For this purpose we conducted twenty-four one-hour experiments involving final year architecture students all working to the same design brief. The experiments were divided into three categories, FTF, full computer mediated collaborative design sessions (CMCD-a; audio-video conferencing plus whiteboard as a shared drawing space) and limited computer mediated collaborative design sessions (CMCD-b; with Lambda MOO used as a chat medium plus whiteboard as a shared drawing space). The experiments were video and audio taped, transcribed and coded into a custom developed coding scheme. The results of the analysed coded data and observations of the videotapes provided evidence that there were noticeable differences between the three categories. There was more design communication and less communication control in the CMCD-b category compared to the FTF and CMCD-a categories. Verbal communication became shorter and straight to the point in CMCD-b as opposed to spontaneous non-stop chat in the other two categories. Moreover in CMCD-b the subjects were observed to be more reflective as well as choosing and re-examining their words to explain ideas to their partners. At times they were seen scrolling back through the text of the conversation in order to re-analyse or interpret the design ideas at hand. This was impossible in FTF and CMCD-a sessions, since the subjects were more spontaneous and audio representations were lost as soon as they were uttered. Also the video channel in the CMCD-a category was ignored and hardly used except for the first few minutes of the experiments, for a brief exchange of light humour on the appearance of each subject. The results obtained from analysing the experiments helped us conclude that different communication channels produce different collaborative environments. The three categories of communication for architectural collaboration explored in our experiments are indicative of the alternatives available to architects now. What is not clear to architects is why they would choose one category over another. We propose that each category has its own strengths and difficulties for architectural collaboration, and therefore should be selected on the basis of the type of communication considered to be most effective for the stage and tasks of the design project.

summary	The Bartlett School of Graduate Studies, University College London (UCL), set up the first MSc in Virtual Environments in the UK in 1995. The course aims to synthesise and build on research work undertaken in the arts, architecture, computing and biological sciences in exploring the realms of the creation of digital and virtual immersive spaces. The MSc is concerned primarily with equipping students from design backgrounds with the skills, techniques and theories necessary in the production of virtual environments. The course examines both virtual worlds as prototypes for real urban or built form and, over the last few years, has also developed an increasing interest in the the practice of architecture in purely virtual contexts. The MSc course is embedded in the UK government sponsored Virtual Reality Centre for the Built Environment which is hosted by the Bartlett School of Architecture. This centre involves the UCL departments of architecture, computer science and geography and includes industrial partners from a number of areas concerned with the built environment including architectural practice, surveying and estate management as well as some software companies and the telecoms industry. The first cohort of students graduated in 1997 and predominantly found work in companies working in the new market area of digital media. This paper aims to outline the nature of the course as it stands, examines the new and ever increasing market for designers within digital media and proposes possible future directions for the course.

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

title	Study of digital morphing tools during the design process - Application of freeware software and of tools in commercial products as well as their integration in AutoCAD
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This research work examines methods of experimental designing with CAAD in a CAD laboratory with architecture students as the testing persons. Thereby the main focus is on the early phase of finding forms, in which different techniques with digital media are tried out in the didactic architectural design lessons. In these work have been traced the influences of the media employed on the design processes and combined the approaches of current CAAD research with aspects from classic design theory. For mathematical rules of proportion, atmospheric influence factors and analogy concepts in architecture, I have developed design methods which have been applied and verified in several series of seminars. (Kirschner, U.: 2000, Thesis, a CAAD supported architectural design teaching, Hamburg, school of arts). Previous experimental exercises showed that morphological sequences of modeling are effective sources for playful designing processes. In the current work these approaches are enhanced and supplemented by different morphological architectural concepts for creating shapes. For this purpose 2D based software like Morphit, Winmorph and other freeware were used. Whereas in the further development of this design technique we used 3D freeware morphing programs like zhu3D or Blender. The resulting morphological shapes were imported in CAD and refined. Ideally the morphing tool is integrated in the modeling environment of the standard software AutoCAD. A digital city model is the starting basis of the design process to guarantee the reference to the reality. The applied design didactic is predicated on the theories of Bernhard Hoesli. The act of designing viewed as „waiting for a good idea“ is, according to him, unteachable; students should, in contrast, learn to judge the „the force of an idea“. On the subject of morphology a form-generating method in the pre-design phase has been tested. Starting from urban-planning lines on an area map, two simple geometric initial images were produced which were merged by means of morphing software. Selected images from this film sequence were extruded with CAAD to produce solid models as sectional drawings. The high motivation of the students and the quality of the design results produced with these simple morphing techniques were the reason for the integration of the artistic and scientific software into the creative shape modeling process with the computer. The students learned in addition to the „bottom up “and „ top down” new design methods. In the presentation the properties and benefits of the morphing tools are presented in tables and are analyzed with regard to the architectural shape generating in an urban context. A catalogue of criteria with the following topics was developed: user friendliness, the ability of integrating the tools or as the case may be the import of data into a CAD environment, the artistic aspects in terms of the flexibility of shape generating as well as the evaluation of the aesthetic consideration of shapes.

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

title	Evolving the Shape of Things to Come - A Comparison of Interactive Evolution and Direct Manipulation for Creative Tasks
source	International Conference on Generative Art
summary	This paper is concerned with differences between direct manipulation and interactive evolutionary design as two fundamentally different interaction styles for creative tasks. Its main contribution to the field of generative design is the treatment of interactive evolutionary design as a general interaction style that can be used to support users in creative tasks. Direct manipulation interfaces, a term coined by Ben Shneiderman in the mid-seventies, are the kind of interface that is characteristic of most modern personal computer application user interfaces. Typically, direct manipulation interfaces incorporate a model of a context (such as a desktop environment) supposedly familiar to users. Rather than giving textual commands (i.e. "remove file.txt", "copy file1.txt file2.txt") to an imagined intermediary between the user and the computer, the user acts directly on the objects of interest to complete a task. Undoubtedly, direct manipulation has played an important role in making computers accessible to non-computer experts. Less certain are the reasons why direct manipulation interfaces are so successful. It has been suggested that this kind of interaction style caters for a sense of directness, control and engagement in the interaction with the computer. Also, the possibilities of incremental action with continuous feedback are believed to be an important factor of the attractiveness of direct manipulation. However, direct manipulation is also associated with a number of problems that make it a less than ideal interaction style in some situations. Recently, new interaction paradigms have emerged that address the shortcomings of direct manipulation in various ways. One example is so-called software agents that, quite the contrary to direct manipulation, act on behalf of the user and alleviate the user from some of the attention and cognitive load traditionally involved in the interaction with large quantities of information. However, this relief comes at the cost of lost user control and requires the user to put trust into a pseudo-autonomous piece of software. Another emerging style of human-computer interaction of special interest for creative tasks is that of interactive evolutionary design (sometimes referred to as aesthetic selection). Interactive evolutionary design is inspired by notions from biological evolution and may be described as a way of exploring a large – potentially infinite – space of possible design configurations based on the judgement of the user. Rather than, as is the case with direct manipulation, directly influencing the features of an object, the user influences the design by means of expressing her judgement of design examples. Variations of interactive evolutionary design have been employed to support design and creation of a variety of objects. Examples of such objects include artistic images, web advertising banners and facial expressions. In order to make an empirical investigation possible, two functional prototypes have been designed and implemented. Both prototypes are targeted at typeface design. The first prototype allows a user to directly manipulate a set of predefined attributes that govern the design of a typeface. The second prototype allows a user to iteratively influence the design of a typeface by means of expressing her judgement of typeface examples. Initially, these examples are randomly generated but will, during the course of interaction, converge upon design configurations that reflect the user’s expressed subjective judgement. In the evaluation of the prototypes, I am specifically interested in users’ sense of control, convergence and surprise. Is it possible to maintain a sense of control and convergence without sacrificing the possibilities of the unexpected in a design process? The empirical findings seem to suggest that direct manipulation caters for a high degree of control and convergence, but with a small amount of surprise and sense of novelty. The interactive evolutionary design prototype supported a lower degree of experienced control, but seems to provide both a sense of surprise and convergence. One plausible interpretation of this is that, on the one hand, direct manipulation is a good interaction style for realizing the user’s intentions. On the other hand, interactive evolutionary design has a potential to actually change the user’s intentions and pre-conceptions of that which is being designed and, in doing so, adds an important factor to the creative process. Based on the empirical findings, the paper discusses situations when interactive evolutionary design may be a serious contender with direct manipulation as the principal interaction style and also how a combination of both styles can be applied.

title	The Creation of a Cumulative Index on CAD: "CUMINCAD"
doi	https://doi.org/10.52842/conf.acadia.2000.018.2
source	ACADIA Quarterly, vol. 19, no. 3, pp. 18-19
summary	To researchers in many disciplines, Internet is quickly becoming the dominating environment to search for publications. Commercial bibliographic databases tend to be too general, are not up-to-date and require special skills and efforts to be searched. On the other hand research is also published on the Web that also enables collaborative creation ofreferences by the specialists in the field. CUMINCAD is such a bibliographic database and compiles papers related to Computer Aided (Architectural) Design. The database is available on the Web and allows searching and browsing in the ways usual on the Web. It provides a ”historical evolution” to learn from previous efforts and draws attention to older original works that could have been ignored because they could not be found on the Web. We believe that CUMINCAD will help focus future CAAD research andimprove the education.

summary	To researchers in every discipline, Internet is quickly becoming the dominating environment to do literature studies. Commercial bibliographic databases tend to be too general, are not up-to-date and require special skills and effort to be searched. On the other hand researchers also publish on the Web and collaboratively that can create indexes of relevant publications. CUMINCAD is a bibliographic index that compiles papers related to computer aided architectural design. Implemented with a database, it allows searching and browsing in the ways usual on the Web. It provides a "historical evolution" to learn from previous efforts and draws attention to older original works that could have been ignored because they could not be found on the Web otherwise. The authors believe that CUMINCAD will help focus future CAAD research and improve the education. CUMINCAD work started in 1998 and is available at www.fagg.uni-lj.si/cumincad/. This paper focusses on the design and development of the database and presents some ideas concerning its advanced use in the analysis of research efforts.
