title	Predicting reflectance functions from complex surfaces
source	Computer Graphics, 26(2):255-264, July 1992
summary	We describe a physically-based Monte Carlo technique for approximating bidirectional re•ectance distribution functions (BRDFs) for a large class of geometries by directly simulating optical scattering. The technique is more general than previous analytical models: it removes most restrictions on surface microgeometry. Three main points are described: a new representation of the BRDF, a Monte Carlo technique to estimate the coef•cients of the representation, and the means of creating a milliscale BRDF from microscale scattering events. These allowthe prediction of scattering from essentially arbitrary roughness geometries. The BRDF is concisely represented by a matrix of spherical harmonic coef•cients; the matrix is directly estimated from a geometric optics simulation, enforcing exact reciprocity. The method applies to roughness scales that are large with respect to the wavelength of light and small with respect to the spatial density at which the BRDF is sampled across the surface; examples include brushed metal and textiles. The method is validated by comparing with an existing scattering model and sample images are generated with a physically-based global illumination algorithm.

summary	This work is part of a long term research programme (Brown and Horton, 1992; Brown and Nahab, 1996; Bassanino, 1999) in which tests and studies have been carried out on various groups of people to investigate their reaction to, and interpretation of different forms of architectural representation. In the work described here a range of architectural schemes were presented using particular representational techniques and media. An experiment was then undertaken on two different groups; architects and lay people. They were presented with a number of schemes displayed using the various techniques and media. The responses are summarised and some comments are made on the effect of computers on perceiving architecture and on communicating architectural ideas arising from an analysis of the responses.

summary	The use of computer tools in architectural practice has been steadily increasing in recent years. Many architectural offices are already using computer tools, mostly for production tasks. Hardly any design is being done with the computer. With the new computer tools, architects are confronted with the challenge to use computers to express their design ideas right from conception. This paper describes a project made for a competition which recently took place in Spain. Sketches and computer models were the only tools used in designing this project. A variety of computer tools were used in different stages of this project: two dimensional drawing tools were used in the early stages, then a three-dimensional modeling program for the development of the design and for the production of final drawings, and a rendering program for final presentation images.

title	Using Higher Level Programming in Interdisciplinary teams as a means of training for Concurrent Engineering
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 14-19

summary	The paper explains a didactical method for training students that has been run three times to date. The premise of the course is to combine students from different faculties into interdisciplinary teams. These teams then have a complex problem to resolve within an extremely short time span. In light of recent works from Joy and Kurzweil, the theme Robotics was chosen as an exercise that is timely, interesting and related, but not central to the studies of the various faculties. In groups of 3 to 5, students from faculties of architecture, computer science and mechanical engineering are entrusted to design, build and program a robot which must successfully execute a prescribed set of actions in a competitive atmosphere. The entire course lasts ten days and culminates with the competitive evaluation. The robots must navigate a labyrinth, communicate with on another and be able to cover longer distances with some speed. In order to simplify the resources available to the students, the Lego Mindstorms Robotic syshed backgrounds instaed of synthetic ones. The combination of digitally produced (scanned) sperical images together with the use of HDR open a wide range of new implementation in the field of architecture, especially in combining synthetic elements in existing buildings, e.g. new interior elements in an existing historical museum).ural presentations in the medium of computer animation. These new forms of expression of design thoughts and ideas go beyond mere model making, and move more towards scenemaking and storytelling. The latter represents new methods of expression within computational environments for architects and designers.its boundaries. The project was conducted using the pedagogical framework of the netzentwurf.de; a relatively well established Internet based communication platform. This means that the studio was organised in the „traditional“ structure consisting of an initial 3 day workshop, a face to face midterm review, and a collective final review, held 3,5 months later in the Museum of Communication in Frankfurt am Main, Germany. In teams of 3 (with each student from a different university and a tutor located at a fourth) the students worked over the Internet to produce collaborative design solutions. The groups ended up with designs that spanned a range of solutions between real and virtual architecture. Examples of the student’s work (which is all available online) as well as their working methods are described. It must be said that the energy invested in the studio by the organisers of the virtual campus (as well as the students who took part) was considerably higher than in normal design studios and the paper seeks to look critically at the effort in relation to the outcomes achieved. The range and depth of the student’s work was surprising to many in the project, especially considering the initial hurdles (both social and technological) that had to overcome. The self-referential nature of the theme, the method and the working environment encouraged the students to take a more philosg and programming a winning robot. These differences became apparent early in the sessions and each group had to find ways to communicate their ideas and to collectively develop them by building on the strengths of each team member.

title	Toward a procedure of computer simulation in the restoration of historical architecture
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 the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

title	Design Modelling and Design Presentation From a Computer-Generated Image Towards a Multi-user Design System
source	CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 137-144

summary	CAD systems regularly offer new techniques for the presentation of design proposals like computer-generated (stereo-) images, animations, holography and virtual reality. These techniques are mainly used for the presentation of a final design or for the presentation of buildings that have already been constructed. As in the course of time the quality of the CAD systems and their users have improved enormously, it is also possible to use these systems for the evaluation of several temporary design proposals during the design process. Since 'beautiful pictures' and 'wonderful animations' have already shown their great value when presenting a design, it is sometimes as if CAD systems are considered suitable for this propose only. Even new techniques like virtual reality systems seem to be valued only through the 'tinted glasses' of the presentation capabilities. Hardly any attention is paid to the possibilities that these new techniques offer as an instrument to support modelling and evaluation during the design process. This article will outline the results of research and development in the field of virtual reality. Virtual reality systems are based on the combination of a number of already existing presentation techniques like photo-realistic images, stereo images and real time animations. The added value of this type of CAD system is determined by the use of a new type of user interface. In effect this interface consists of sensors that register how its user moves and looks around. Through this, and by using a so- called 'eye phone' (comparable to stereo headphones for sound) the user, with some imaginative powers, thinks he is standing in the environment that he modelled, or in front of his building design. After this we will first sketch the outlines of some presentation techniques, that can also be found in a virtual reality system. Special attention will be paid to some specific characteristics of these techniques themselves. Next, a more detailed description will be given of virtual reality systems, focusing on the system that is being developed at Calibre itself.

title	Cooperative work environment using virtual workspace
source	Proceedings of the Conference on Computer-Supported Cooperative Work: 226-232. New York: The Association for Computing Machinery
summary	A virtual environment, which is created by computer graphics and an appropriate user interface, can be used in many application fields, such as teleopetution, telecommunication and real time simulation. Furthermore, if this environment could be shared by multiple users, there would be more potential applications. Discussed in this paper is a case study of building a prototype of a cooperative work environment using a virtual environment, where more than two people can solve problemscooperatively, including design strategies and implementirig issues. An environment where two operators can directly grasp, move or release stereoscopic computer graphics images by hand is implemented. The system is built by combining head position tracking stereoscopic displays, hand gesture input devices and graphics workstations. Our design goal is to utilize this type of interface for a future teleconferencing system. In order to provide good interactivity for users, we discuss potential bottlenecks and their solutions. The system allows two users to share a virtual environment and to organize 3-D objects cooperatively.

title	Teaching Design By Analysis of Precedents
source	CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 477-496
doi	https://doi.org/10.52842/conf.ecaade.1992.477
summary	Designers, using their intuitive understanding of the decomposition of particular design objects, whether in terms of structural, functional, or some other analytical framework, should be able to interact with computational environments such that the understanding they achieve in turn invokes changes or transformations to the spatial properties of design proposals. Decompositions and transformations of design precedents can be a very useful method of enabling design students to develop analytical strategies. The benefit of an analytical approach is that it can lead to a structured understanding of design precedents. This in turn allows students to develop their own insights and ideas which are central to the activity of designing. The creation of a 3-D library of user-defined models of precedents in a computational environment permits an under-exploited method of undertaking analysis, since by modelling design precedents through the construction of 3-D Computer-Aided Architectural Design (CAAD) models, and then analytically decomposing them in terms of relevant features, significant insights into the nature of designs can be achieved. Using CAAD systems in this way, therefore, runs counter to the more common approach of detailed modelling, rendering and animation; which produces realistic pictures that do not reflect the design thinking that went into their production. The significance of the analytical approach to design teaching is that it encourages students to represent design ideas, but not necessarily the final form of design objects. The analytical approach therefore, allows students to depict features and execute tasks that are meaningful with respect to design students' own knowledge of particular domains. Such computational interaction can also be useful in helping students explore the consequences of proposed actions in actual design contexts.

title	Digital Architecture in CAD studio and Internet-based competition

summary	Architectural design has been changing because of the vast and creative use of computer in different ways. From the viewpoint of designing itself, computer has been used as drawing tools in the latter phase of design (Mitchell 1977; Coyne et al. 1990), presentation and simulation tools in the middle phase (Liu and Bai 2000), and even critical media which triggers creative thinking in the very early phase (Maher et al. 2000; Liu 1999; Won 1999). All the various roles that computer can play have been adopted in a number of professional design corporations and so-called computer-aided design (CAD) studio in schools worldwide (Kvan 1997, 2000; Cheng 1998). The processes and outcomes of design have been continuously developing to capture the movement of the computer age. However, from the viewpoint of social-cultural theories of architecture, the evolvement of design cannot be achieved solely by designers or design processes. Any new idea of design can be accepted socially, culturally and historically only under one condition: The design outcomes could be reviewed and appreciated by critics in the field at the time of its production (Csikszentmihalyi 1986, 1988; Schon and Wiggins 1992; Liu 2000). In other words, aspects of design production (by designers in different design processes) are as critical as those of design appreciation (by critics in different review processes) in the observation of the future trends of architecture.Nevertheless, in the field of architectural design with computer and Internet, that is, so-called computer-aided design computer-mediated design, or internet-based design, most existing studies pay more attentions to producing design in design processes as mentioned above. Relatively few studies focus on how critics act and how they interact with designers in the review processes. Therefore, this study intends to investigate some evolving phenomena of the interaction between design production and appreciation in the environment of computer and Internet.This paper takes a CAD studio and an Internet-based competition as examples. The CAD studio includes 7 master's students and 2 critics, all from the same countries. The Internet-based competition, held in year 2000, includes 206 designers from 43 counties and 26 critics from 11 countries. 3 students and the 2 critics in the CAD studio are the competition participating designers and critics respectively. The methodological steps are as follows: 1. A qualitative analysis: observation and interview of the 3 participants and 2 reviewers who join both the CAD studio and the competition. The 4 analytical criteria are the kinds of presenting media, the kinds of supportive media (such as verbal and gesture/facial data), stages of the review processes, and interaction between the designer and critics. The behavioral data are acquired by recording the design presentation and dialogue within 3 months. 2. A quantitative analysis: statistical analysis of the detailed reviewing data in the CAD studio and the competition. The four 4 analytical factors are the reviewing time, the number of reviewing of the same project, the comparison between different projects, and grades/comments. 3. Both the qualitative and quantitative data are cross analyzed and discussed, based on the theories of design thinking, design production/appreciation, and the appreciative system (Goodman 1978, 1984).The result of this study indicates that the interaction between design production and appreciation during the review processes could differ significantly. The review processes could be either linear or cyclic due to the influences from the kinds of media, the environmental discrepancies between studio and Internet, as well as cognitive thinking/memory capacity. The design production and appreciation seem to be more linear in CAD studio whereas more cyclic in the Internet environment. This distinction coincides with the complementary observations of designing as a linear process (Jones 1970; Simon 1981) or a cyclic movement (Schon and Wiggins 1992). Some phenomena during the two processes are also illustrated in detail in this paper.This study is merely a starting point of the research in design production and appreciation in the computer and network age. The future direction of investigation is to establish a theoretical model for the interaction between design production and appreciation based on current findings. The model is expected to conduct using revised protocol analysis and interviews. The other future research is to explore how design computing creativity emerge from the process of producing and appreciating.

title	A Computational Framework for Supporting Creative Architectural Design
source	New York: John Wiley & Sons, 1992. pp. 17-34 : ill. includes Bibliography
summary	Design can be considered a process leading to the definition of a physical form that achieves a certain predefined set of performance criteria. The process comprises three distinct operations: (1) Definition of the desired set of performance criteria (design goals); (2) generation of alternative design solutions; (3) evaluation of the expected performances of alternative design solutions, and comparing them to the predefined criteria. Difficulties arise in performing each one of the three operations, and in combining them into a purposeful unified process. Computational techniques were developed to assist each of the three operations. A comprehensive and successful computational design assistant will have to recognize the limitations of current computational techniques, and incorporate a symbiosis between the machine and the human designer. This symbiosis comprises allocating design tasks between the designer and the computer in a manner that is most appropriate for the task at hand. The task allocation must, therefore, be done dynamically, responding to the changing circumstances of the design process. This report proposes a framework for such a symbiotic partnership, which comprises four major components: (1) User interface and design process control; (2) design goals; (3) evaluators; (4) database

title	Visions unfolding: architecture in the age of electronic media
source	Domus, 1/92
summary	During the fifty years sinee the Second World War, a paradigm shift has taken place that should have profoundly affected architecture: this was the shift from the mechanicai paradigm to the electrorlic one. This change can be simply understood by comparing the impact of the role of the human subject on such primary modes of reproduction as the photograph and the fax; the photograph within the mechanical paradigm, the fax within the electronic one. In photographic reproduction the subiect still maintains a controlled interaction with the object. A photograph can be developed with more or less contrast, texture or clarity.

summary	The prime objective of this study is the analysis and the understanding of the underlying architectural principles (ideas) behind the particular seminar work that they have been given. Although this study is limited to one building its real significance lies not only in what it tells us about it, but also what it reveals about architecture itself. By distilling and comparing these buildings and stripping away the circumstances of their creation, we are shown universal principles of their design. This universality invites comparison to other buildings far removed in time and place.

title	To Master a Tool
source	Proceedings of the 4rd European Full-Scale Modelling Conference / Lausanne (Switzerland) 9-12 September 1992, Part B, p. 15
summary	The tool here is the computer or to be precise, a unit that includes the computer, the peripherals and the software needed to fulfill a task. These tools are getting very sophisticated and user interfaces extremly friendly, therefore it is very easy to become the slave of such electronic tools and reach self satisfaction with strait forward results and attractive images. In order to master and not to become slaves of sophisticated tools, a very solid knowledge of related fields or domains of application becomes necessary. In the case of this seminar, full scale modelling, is a way to understand the relation between a mental model and it's full-scale modelling, it is a way of communicating what is in a designers mind. Computers and design programs can have the same goal, rather than chosing one method or the other let us try to say how important it is today to complement designing with computer with other means and media such as full scale modelling, and what computer modelling and simulation can bring to full scale modelling or other means.

doi	https://doi.org/10.52842/conf.acadia.2000.137
summary	The computer is a relatively new tool in the practice of Architecture. Since its introduction, there has been a desire amongst designers to use this new tool quite early in the design process. However, contrary to this desire, most Architects today use pen and paper in the very early stages of design to sketch. Architects solve problems by thinking visually. One of the most important tools that the Architect has at his disposal in the design process is the hand sketch. This iterative way of testing ideas and informing the design process with images fundamentally directs and aids the architect’s decision making. It has been said (Schön and Wiggins 1992) that sketching is about the reflective conversation designers have with images and ideas conveyed by the act of drawing. It is highly dependent on feedback. This “conversation” is an area worthy of investigation. Understanding this “conversation” is significant to understanding how we might apply the computer to enhance the designer’s ability to capture, manipulate and reflect on ideas during conceptual design. This paper discusses sketching and its relation to design thinking. It explores the conversations that designers engage in with the media they use. This is done through the explanation of a protocol analysis method. Protocol analysis used in the field of psychology, has been used extensively by Eastman et al (starting in the early 70s) as a method to elicit information about design thinking. In the pilot experiment described in this paper, two persons are used. One plays the role of the “hand” while the other is the “mind”- the two elements that are involved in the design “conversation”. This variation on classical protocol analysis sets out to discover how “intelligent” the hand should be to enhance design by reflection. The paper describes the procedures entailed in the pilot experiment and the resulting data. The paper then concludes by discussing future intentions for research and the far reaching possibilities for use of the computer in architectural studio teaching (as teaching aids) as well as a digital design assistant in conceptual design.

title	Computer Aided Structural Design in Architectural Instruction

doi	https://doi.org/10.52842/conf.ecaade.1992.443
summary	In schools of architecture there is a tendency to associate the use of computers solely with the production of graphic images as part of the architectural design process. However, if the architecture is to work as a building it is also essential that technical aspects of the design are adequately investigated. One of the problem areas for most architectural students is structural design and they are often reluctant to use hand calculations to determine sizes of structural elements within their projects. In recent years, much of the drudgery of hand calculation has been removed from the engineer by the use of computers, and this has, hopefully, allowed a more thorough investigation of conceptual ideas and alternatives. The same benefit is now becoming available to architectural students. This is in the form of structural analysis and design programs that can be used, even by those having a limited knowledge of structural engineering, to assess the stability of designs and obtain approximate sizes for individual structural elements. The paper discusses how the use of such programs is taught, within the School of Architecture at Nottingham. Examples will be given of how they can assist students in the architectural design process. In particular, the application of GLULAM, a program for estimating sizes of laminated timber elements and SAND, a structural analysis and design package, will be described.

title	An Approach to 3D Conceptual Modelling
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	This article presents a 3D user interface required by the development of conceptual modeling. This 3D user interface provides a new structure for solving the problems of difficult interface operations and complicated commands due to the application of CAD 2D interface for controlling 3D environment. The 3D user interface integrates the controlling actions of “seeing – moving –seeing” while designers are operating CAD (Schön and Wiggins, 1992). Simple gestures are used to control the operations instead. The interface also provides a spatial positioning method which helps designers to eliminate the commands of converting a coordinate axis. The study aims to discuss the provision of more intuitively interactive control through CAD so as to fulfil the needs of designers. In our practices and experiments, a pair of LED gloves equipped with two CCD cameras for capturing is used to sense the motions of hands and positions in 3D. In addition, circuit design is applied to convert the motions of hands including selecting, browsing, zoom in / zoom out and rotating to LED switches in different colours so as to identify images.

title	Architectural computer vision: Automated recognition of architectural drawings
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Computer vision offers the ability to transform digitized drawings into documents that can be used with computer systems. Recognition of digitized drawings can occur at the levels of (a) geometric elements, (b) building elements, and (c) spatial articulation. The last two levels apply not only to digitized images but also to computer-produced ones. The enormous burden placed on the user for inputting and manipulating CAD drawings suggests that automated recognition can add to the capabilities of CAD by making the computer more flexible with respect to inputting design information and more responsive to the actual concerns of the designer.

title	Monitoring the Dynamics of Informal Settlements in Dar Es Salaam by Remote Sensing: Exploring the Use of Spot, Ers and Small Format Aerial Photography
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	Dar es Salaam is exemplary for cities in the developing world facing an enormous population growth. In the last decades, unplanned settlements have tremendously expanded, causing that around 70 percent of the urban dwellers are living now-a-days in these areas. Tools for monitoring such tremendous growth are relatively weak in developing countries, thus an effective satellite based monitoring system can provide a useful instrument for monitoring the dynamics of urban development. An investigation to asses the ability of extracting reliable information on the expansion and consolidation levels (density) of urban development of the city of Dar es Salaam from SPOT-HRV and ERS-SAR images is described. The use of SPOT and ERS should provide data that is complementary to data derived from the most recent aerial photography and from digital topographic maps. In a series of experiments various classification and fusion techniques are applied to the SPOT-HRV and ERS-SAR data to extract information on building density that is comparable to that obtained from the 1992 data. Ultimately, building density is estimated by linear and non-linear regression models on the basis of an one ha kernel and further aggregation is made to the level of informal settlements for a final analysis. In order to assess the reliability, use is made of several sample areas that are relatively stable over the study period, as well as, of data derived from small format aerial photography. The experiments show a high correlation between the density data derived from the satellite images and the test areas.

summary	As well as learning traditional design techniques, students in architecture courses learn how to use powerful workstations with CAD systems, color scanners and laser printers and software for the rendering, compositing and animating of their designs. They learn to use raytracing and radiosity rendering systems to provide visual realism, alpha-channel compositing systems to put a client in the picture (literally) or the design in situ, and keyframe animation systems to allow realistic walkthroughs. Student Presentations are now based on videos, photographic slides, slide shows or real time animation. Images (as data files) are imported into full color publishing systems for final year thesis presentation. The architectural graphics environment at Curtin University facilitates the integration of slide and video examples of raytraced and chroma-keyed images with computer aided design techniques for architectural student presentations.

title	USER PARTICIPATION IN DESIGN: TECHNIQUES FOR DIALOGUE
source	Proceedings of the 4rd European Full-Scale Modelling Conference / Lausanne (Switzerland) 9-12 September 1992, Part B, pp. 17-24
summary	Many projects in which users participate in the design process are merely examples of professionals communicating their ideas to their clients. Conventional computer systems can be powerful tools for helping designers to present design informations to lay audiences, but when combined with computer modelling and simulation, they create opportunities for users to construct their own sequences of images and thus explore designs from their own viewpoint. Building on extensive experience of traditional methods of user participation, this paper explores the use of narratives to create dialogues between users, designers and computers. The concept of "design stories" as a route to fully shared creativity is explained. The paper also argues that this approach is needed to bring into focus design issues that cannot be described or resolved by computer modelling alone.
