title	Designing solid objects using interactive sketch interpretation
source	Computer Graphics (1992 Symposium on Interactive 3D Graphics), 25(2):117-126, Mar. 1992
summary	Before the introduction of Computer Aided Design and solid modeling systems, designers had developed a set of techniques for designing solid objects by sketching their ideas on pencil and paper and refining them into workable designs. Unfortunately, these techniques are different from those for designing objects using a solid modeler. Not only does this waste avast reserve of talent and experience (people typically start drawing from the moment they can hold a crayon), but it also has a more fundamental problem: designers can use their intuition more effectively when sketching than they can when using a solid modeler. Viking is a solid modeling system whose user-interface is based on interactive sketch interpretation. Interactive sketch interpretation lets the designer create a line-drawing of a de- sired object while Viking generates a three-dimensional ob- ject description. This description is consistent with both the designer's line-drawing, and a set of geometric constraints either derived from the line-drawing or placed by the de- signer. Viking's object descriptions are fully compatible with the object descriptions used by traditional solid modelers. As a result, interactive sketch interpretation can be used with traditional solid modeling techniques, combining the advan- tages of both sketching and solid modeling.

title	Teaching Design By Analysis of Precedents

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	Using conceptual modelling and an object-oriented environment to support building cost control during early design
source	College of Architecture and Urban Planning, University of Michigan
summary	This research investigated formal information modelling techniques and the object-oriented knowledge representation on the domain of building cost control during early design stages. The findings contribute to an understanding of the advantages and disadvantages of applying formal modelling techniques to the analysis of architectural problems and the representation of domain knowledge in an object-oriented environment. In this study, information modelling techniques were reviewed, formal information analysis was performed, a conceptual model based on the cost control problem domain was created, a computational model based on the object-oriented approach was developed, a mechanism to support information broadcasting for representing interrelationships was implemented, and an object-oriented cost analysis system for early design (OBCIS) was demonstrated. The conceptual model, based on the elemental proposition analysis of NIAM, supports a formal approach for analyzing the problem domain; the analysis results are represented by high-level graphical notations, based on the AEC Building System Model, to visually display the information framework of the domain. The conceptual model provides an intermediate step between the system designer's view of the domain and the internal representation of the implementation platform. The object-oriented representation provides extensive data modelling abilities to help system designers intuitively represent the semantics of the problem domain. The object-oriented representation also supports more structured and integrated modules than conventional programming approaches. Although there are many advantages to applying this technique to represent the semantics of cost control knowledge, there are several issues which need to be considered: no single satisfactory classification method can be directly applied; object-oriented systems are difficult to learn; and designing reusable classes is difficult. The dependency graph and information broadcasting implemented in this research is an attempt to represent the interrelationships between domain objects. The mechanism allows users to explicitly define the interrelationships, based on semantic requirements, among domain objects. In the conventional approach, these relationships are directly interpreted by system designers and intertwined into the programming code. There are several issues which need to be studied further: indirect dependency relationship, conflict resolution, and request-update looping based on least-commitment approach.

title	Full-Scale Simulations as Tool for Developing Spatial Design Ability
source	Proceedings of the 4rd European Full-Scale Modelling Conference / Lausanne (Switzerland) 9-12 September 1992, Part C, pp. 7-10
summary	Spatial Design Ability has been defined as the capability to anticipate effects (psychological impressions on potential observers or users) produced by mental manipulation of elements of architectural or urban spaces. This ability, of great importance in choosing the appropriate option during the design process, is not specifically developed in schools of architecture and is partially obtained as a by-product of drawing, designing or architectural criticism. We use our Laboratory as a tool to present spaces to people so that they can evaluate them. By means of a series of exercises, students confront their anticipations with the psychological impressions produced in other people. For this occasion, we present an experience in which students had to propose a space for an exhibition hag in which architectural projects (student thesis) were to be shown. Following the Spatial Design Ability Development Model which we have been using for several years, students first get acquainted with the use of evaluation instruments for psychological impressions as well as with research methodology. In this case, due to the short period available, we reduced research to investigate the effects produced by the manipulation of only 2 independents variables: students manipulated first the form of the roof, walls and interiors elements, secondly, color and texture of those elements. They evaluated spatial quality, character and the other psychological impressions that manipulations produced in people. They used three dimensional scale models 1/10 and 1/1.

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.

title	Computers and Design Activities: Their Mediating Role in Engineering Education
source	Sociomedia, ed. Edward Barret. MIT Press
summary	Sociomedia: With all the new words used to describe electronic communication (multimedia, hypertext, cyberspace, etc.), do we need another one? Edward Barrett thinks we do; hence, he coins the term "sociomedia." It is meant to displace a computing economy in which technicity is hypostasized over sociality. Sociomedia, a compilation of twenty-five articles on the theory, design and practice of educational multimedia and hypermedia, attempts to re-value the communicational face of computing. Value, of course, is "ultimately a social construct." As such, it has everything to do with knowledge, power, education and technology. The projects discussed in this book represent the leading edge of electronic knowledge production in academia (not to mention major funding) and are determining the future of educational media. For these reasons, Sociomedia warrants close inspection. Barrett's introduction sets the tone. For him, designing computer media involves hardwiring a mechanism for the social construction of knowledge (1). He links computing to a process of social and communicative interactivity for constructing and desseminating knowledge. Through a mechanistic mapping of the university as hypercontext (a huge network that includes classrooms as well as services and offices), Barrett models intellectual work in such a way as to avoid "limiting definitions of human nature or human development." Education, then, can remain "where it should be--in the human domain (public and private) of sharing ideas and information through the medium of language." By leaving education in a virtual realm (where we can continue to disagree about its meaning and execution), it remains viral, mutating and contaminating in an intellectually healthy way. He concludes that his mechanistic model, by means of its reductionist approach, preserves value (7). This "value" is the social construction of knowledge. While I support the social orientation of Barrett's argument, discussions of value are related to power. I am not referring to the traditional teacher-student power structure that is supposedly dismantled through cooperative and constructivist learning strategies. The power to be reckoned with in the educational arena is foundational, that which (pre)determines value and the circulation of knowledge. "Since each of you reading this paragraph has a different perspective on the meaning of 'education' or 'learning,' and on the processes involved in 'getting an education,' think of the hybris in trying to capture education in a programmable function, in a displayable object, in a 'teaching machine'" (7). Actually, we must think about that hybris because it is, precisely, what informs teaching machines. Moreover, the basic epistemological premises that give rise to such productions are too often assumed. In the case of instructional design, the episteme of cognitive sciences are often taken for granted. It is ironic that many of the "postmodernists" who support electronic hypertextuality seem to have missed Jacques Derrida's and Michel Foucault's "deconstructions" of the epistemology underpinning cognitive sciences (if not of epistemology itself). Perhaps it is the glitz of the technology that blinds some users (qua developers) to the belief systems operating beneath the surface. Barrett is not guilty of reactionary thinking or politics; he is, in fact, quite in line with much American deconstructive and postmodern thinking. The problem arises in that he leaves open the definitions of "education," "learning" and "getting an education." One cannot engage in the production of new knowledge without orienting its design, production and dissemination, and without negotiating with others' orientations, especially where largescale funding is involved. Notions of human nature and development are structural, even infrastructural, whatever the medium of the teaching machine. Although he addresses some dynamics of power, money and politics when he talks about the recession and its effects on the conference, they are readily visible dynamics of power (3-4). Where does the critical factor of value determination, of power, of who gets what and why, get mapped onto a mechanistic model of learning institutions? Perhaps a mapping of contributors' institutions, of the funding sources for the projects showcased and for participation in the conference, and of the disciplines receiving funding for these sorts of projects would help visualize the configurations of power operative in the rising field of educational multimedia. Questions of power and money notwithstanding, Barrett's introduction sets the social and textual thematics for the collection of essays. His stress on interactivity, on communal knowledge production, on the society of texts, and on media producers and users is carried foward through the other essays, two of which I will discuss. Section I of the book, "Perspectives...," highlights the foundations, uses and possible consequences of multimedia and hypertextuality. The second essay in this section, "Is There a Class in This Text?," plays on the robust exchange surrounding Stanley Fish's book, Is There a Text in This Class?, which presents an attack on authority in reading. The author, John Slatin, has introduced electronic hypertextuality and interaction into his courses. His article maps the transformations in "the content and nature of work, and the workplace itself"-- which, in this case, is not industry but an English poetry class (25). Slatin discovered an increase of productive and cooperative learning in his electronically- mediated classroom. For him, creating knowledge in the electronic classroom involves interaction between students, instructors and course materials through the medium of interactive written discourse. These interactions lead to a new and persistent understanding of the course materials and of the participants' relation to the materials and to one another. The work of the course is to build relationships that, in my view, constitute not only the meaning of individual poems, but poetry itself. The class carries out its work in the continual and usually interactive production of text (31). While I applaud his strategies which dismantle traditional hierarchical structures in academia, the evidence does not convince me that the students know enough to ask important questions or to form a self-directing, learning community. Stanley Fish has not relinquished professing, though he, too, espouses the indeterminancy of the sign. By the fourth week of his course, Slatin's input is, by his own reckoning, reduced to 4% (39). In the transcript of the "controversial" Week 6 exchange on Gertrude Stein--the most disliked poet they were discussing at the time (40)--we see the blind leading the blind. One student parodies Stein for three lines and sums up his input with "I like it." Another, finds Stein's poetry "almost completey [sic] lacking in emotion or any artistic merit" (emphasis added). On what grounds has this student become an arbiter of "artistic merit"? Another student, after admitting being "lost" during the Wallace Steven discussion, talks of having more "respect for Stevens' work than Stein's" and adds that Stein's poetry lacks "conceptual significance[, s]omething which people of varied opinion can intelligently discuss without feeling like total dimwits...." This student has progressed from admitted incomprehension of Stevens' work to imposing her (groundless) respect for his work over Stein's. Then, she exposes her real dislike for Stein's poetry: that she (the student) missed the "conceptual significance" and hence cannot, being a person "of varied opinion," intelligently discuss it "without feeling like [a] total dimwit." Slatin's comment is frightening: "...by this point in the semester students have come to feel increasingly free to challenge the instructor" (41). The students that I have cited are neither thinking critically nor are their preconceptions challenged by student-governed interaction. Thanks to the class format, one student feels self-righteous in her ignorance, and empowered to censure. I believe strongly in student empowerment in the classroom, but only once students have accrued enough knowledge to make informed judgments. Admittedly, Slatin's essay presents only partial data (there are six hundred pages of course transcripts!); still, I wonder how much valuable knowledge and metaknowledge was gained by the students. I also question the extent to which authority and professorial dictature were addressed in this course format. The power structures that make it possible for a college to require such a course, and the choice of texts and pedagogy, were not "on the table." The traditional professorial position may have been displaced, but what took its place?--the authority of consensus with its unidentifiable strong arm, and the faceless reign of software design? Despite Slatin's claim that the students learned about the learning process, there is no evidence (in the article) that the students considered where their attitudes came from, how consensus operates in the construction of knowledge, how power is established and what relationship they have to bureaucratic insitutions. How do we, as teaching professionals, negotiate a balance between an enlightened despotism in education and student-created knowledge? Slatin, and other authors in this book, bring this fundamental question to the fore. There is no definitive answer because the factors involved are ultimately social, and hence, always shifting and reconfiguring. Slatin ends his article with the caveat that computerization can bring about greater estrangement between students, faculty and administration through greater regimentation and control. Of course, it can also "distribute authority and power more widely" (50). Power or authority without a specific face, however, is not necessarily good or just. Shahaf Gal's "Computers and Design Activities: Their Mediating Role in Engineering Education" is found in the second half of the volume, and does not allow for a theory/praxis dichotomy. Gal recounts a brief history of engineering education up to the introduction of Growltiger (GT), a computer-assisted learning aid for design. He demonstrates GT's potential to impact the learning of engineering design by tracking its use by four students in a bridge-building contest. What his text demonstrates clearly is that computers are "inscribing and imaging devices" that add another viewpoint to an on-going dialogue between student, teacher, earlier coursework, and other teaching/learning tools. The less proficient students made a serious error by relying too heavily on the technology, or treating it as a "blueprint provider." They "interacted with GT in a way that trusted the data to represent reality. They did not see their interaction with GT as a negotiation between two knowledge systems" (495). Students who were more thoroughly informed in engineering discourses knew to use the technology as one voice among others--they knew enough not simply to accept the input of the computer as authoritative. The less-advanced students learned a valuable lesson from the competition itself: the fact that their designs were not able to hold up under pressure (literally) brought the fact of their insufficient knowledge crashing down on them (and their bridges). They also had, post factum, several other designs to study, especially the winning one. Although competition and comparison are not good pedagogical strategies for everyone (in this case the competitors had volunteered), at some point what we think we know has to be challenged within the society of discourses to which it belongs. Students need critique in order to learn to push their learning into auto-critique. This is what is lacking in Slatin's discussion and in the writings of other avatars of constructivist, collaborative and computer-mediated pedagogies. Obviously there are differences between instrumental types of knowledge acquisition and discoursive knowledge accumulation. Indeed, I do not promote the teaching of reading, thinking and writing as "skills" per se (then again, Gal's teaching of design is quite discursive, if not dialogic). Nevertheless, the "soft" sciences might benefit from "bridge-building" competitions or the re-institution of some forms of agonia. Not everything agonistic is inhuman agony--the joy of confronting or creating a sound argument supported by defensible evidence, for example. Students need to know that soundbites are not sound arguments despite predictions that electronic writing will be aphoristic rather than periodic. Just because writing and learning can be conceived of hypertextually does not mean that rigor goes the way of the dinosaur. Rigor and hypertextuality are not mutually incompatible. Nor is rigorous thinking and hard intellectual work unpleasurable, although American anti-intellectualism, especially in the mass media, would make it so. At a time when the spurious dogmatics of a Rush Limbaugh and Holocaust revisionist historians circulate "aphoristically" in cyberspace, and at a time when knowledge is becoming increasingly textualized, the role of critical thinking in education will ultimately determine the value(s) of socially constructed knowledge. This volume affords the reader an opportunity to reconsider knowledge, power, and new communications technologies with respect to social dynamics and power relationships.

title	Constructed Representations and Their Functions in Computational Models of Designing
doi	https://doi.org/10.52842/conf.caadria.2000.215

summary	This paper re-examines the conclusions made by Schön and Wiggins in 1992 that computers were unable to reproduce processes crucial to designing. We propose that recent developments in artificial intelligence and design computing put us in a position where we can begin to computationally model designing as conceived by Schön and Wiggins. We present a computational model of designing using situated processes that construct representations. We show how constructed representations support computational processes that model the different kinds of seeing reported in designing. We also present recently developed computational processes that can identify unexpected consequences of design actions using adaptive novelty detection.

title	From Sketches to Computer Images: A Strategy for the Application of Computers in Architectural Design
doi	https://doi.org/10.52842/conf.ecaade.1992.331
source	CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 331-350
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	Maximising the Benefits of CAD Systems in Architectural Education
doi	https://doi.org/10.52842/conf.ecaade.1994.x.u8n
source	The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, p. 228
summary	The positive impact of Computer Aided Design (CAD) in professional architectural practice has been in focus in recent times but relatively little has been written on its significance in the education of the contemporary architect. It is common knowledge that the profession of architecture is currently undergoing enormous strains as it battles to keep abreast of trends and developments in a period of series of rapid advancement in science, technology and management (RIBA, 1992). Whilst attempts are being made to redress the shortcomings of the profession in the above context, the requirements for architectural education are yet to forge a coherent strategy for the implementation of CAD/IT in the curriculum of schools of architecture. In almost every other field, including engineering, medicine and the humanities, computing application to problem-solving and decision-making is seen as a way forward as we move into 21st century. Architectural education must integrate CAD/IT into the teaching of core modules that give the architect distinctive competence: studio design. That is one of the best ways of doing justice to the education of the architect of today and the future. Some approaches to the teaching of CAD in schools of architecture have been touched upon in the recent past. Building upon this background as well as an understanding of the nature of design teaching/learning, this paper examines ways of maximising the benefits of CAD systems in architectural education and of bringing computer aided designing into the studio not only to enhance design thinking and creativity but also to support interactive processes. In order to maximise or optimise any function, one approach is to use the hard systems methodology which utilises analytic, analogic and iconic models to show the effect of those factors which are significant for the purposes being considered. The other approach is to use the soft systems methodology in which the analysis encompasses the concept of a human activity system as a means of improving a situation. The use of soft systems methodology is considered more appropriate for dealing with the problem of design which is characterised by a flux of interacting events and ideas that unroll through time. The paper concludes that the main impediment to maximising the benefits of CAD systems in architectural education is not only the inappropriate definition of the objectives for the implementation of CAD education but also that the control subsystems are usually ill-structured and relatively poorly defined. Schools must attempt to define a coherent and consistent policy on the use of CAD systems as an integral part of studio design and evolve an in-house strategic and operational controls that enable the set objectives to be met. Furthermore, it is necessary to support the high level of productivity from CAD systems with a more efficient management system, especially in dealing with communication, data sharing via relational database, co-ordination and integration. Finally, the use of soft systems methodology is recommended as the way forward to optimising CAD systems in design education as it would provide continuous improvements while maintaining their productive value.

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	Spatial Perception in Virtual Environments : Evaluating an Architectural Application
source	University of Washington
summary	Over the last several years, professionals from many different fields have come to the Human Interface Technology Laboratory (H.I.T.L) to discover and learn about virtual environments. In general, they are impressed by their experiences and express the tremendous potential the tool has in their respective fields. But the potentials are always projected far in the future, and the tool remains just a concept. This is justifiable because the quality of the visual experience is so much less than what people are used to seeing; high definition television, breathtaking special cinematographic effects and photorealistic computer renderings. Instead, the models in virtual environments are very simple looking; they are made of small spaces, filled with simple or abstract looking objects of little color distinctions as seen through displays of noticeably low resolution and at an update rate which leaves much to be desired. Clearly, for most applications, the requirements of precision have not been met yet with virtual interfaces as they exist today. However, there are a few domains where the relatively low level of the technology could be perfectly appropriate. In general, these are applications which require that the information be presented in symbolic or representational form. Having studied architecture, I knew that there are moments during the early part of the design process when conceptual decisions are made which require precisely the simple and representative nature available in existing virtual environments. This was a marvelous discovery for me because I had found a viable use for virtual environments which could be immediately beneficial to architecture, my shared area of interest. It would be further beneficial to architecture in that the virtual interface equipment I would be evaluating at the H.I.T.L. happens to be relatively less expensive and more practical than other configurations such as the "Walkthrough" at the University of North Carolina. The set-up at the H.I.T.L. could be easily introduced into architectural firms because it takes up very little physical room (150 square feet) and it does not require expensive and space taking hardware devices (such as the treadmill device for simulating walking). Now that the potential for using virtual environments in this architectural application is clear, it becomes important to verify that this tool succeeds in accurately representing space as intended. The purpose of this study is to verify that the perception of spaces is the same, in both simulated and real environment. It is hoped that the findings of this study will guide and accelerate the process by which the technology makes its way into the field of architecture.

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.

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.

title	3DM: A three-dimensional modeler using a head-mounted display
source	Proceedings of the 1992 Symposium on Interactive 3D Graphics (Cambridge, Mass., March 29- April 1, 1992.), 135-138
summary	3dm is a three dimensional (3D) surface modeling program that draws techniques of model manipulation from both CAD and drawing programs and applies them to modeling in an intuitive way. 3dm uses a head-mounted display (HMD) to simplify the problem of 3D model manipulation and understanding. A HMD places the user in the modeling space, making three dimensional relationships more understandable. As a result, 3dm is easy to learn how to use and encourages experimentation with model shapes.

summary	Energy performance is a crucial step toward responsible design. Currently there are many tools that can be applied to reach this goal with reasonable accuracy. Often times, however, major flaws are not discovered until the final stage of design when it is too late to change. Not only are existing simulation models complicated to apply at the conceptual design stage, but energy principles and their applications are also abstract and hard to visualize. Because of the lack of suitable tools to visualize energy analysis output, energy conservation concepts fail to be integrated into the building design. For these reasons, designers tend not to apply energy conservation concepts at the early design stage. However, since computer graphics is a new phase of visual communication in design process, the above problems might be solved properly through a computerized graphical interface in the conceptual design stage. The research described in this paper is the result of exploring the concept of using computer graphics to support energy efficient building designs. It focuses on the visualization of building energy through a highly interactive graphical interface in the early design stage.

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	Re-tiling polygonal surfaces
source	E.E. Catmull, (ed) Computer Graphics (Siggraph ¥92 proc.), vol 26, pp. 55-64, July 1992
summary	This paper presents an automatic method of creating surface models at several levels of detail from an original polygonal description of a given object. Representing models at various levels of detail is important for achieving high frame rates in interactive graphics applications and also for speeding-up the off-line rendering of complex scenes. Unfortunately, generating these levels of detail is a time-consuming task usually left to a human modeler. This paper shows how a new set of vertices can be distributed over the surface of a model and connected to one another to create a re-tiling of a surface that is faithful to both the geometry and the topology of the original surface. The main contributions of this paper are: 1) a robust method of connecting together new vertices over a surface, 2) a way of using an estimate of surface curvature to distribute more new vertices at regions of higher curvature and 3) a method of smoothly interpolating between models that represent the same object at different levels of detail. The key notion in the re-tiling procedure is the creation of an intermediate model called the mutual tessellation of a surface that contains both the vertices from the original model and the new points that are to become vertices in the re-tiled surface. The new model is then created by removing each original vertex and locally re-triangulating the surface in a way that matches the local connectedness of the initial surface. This technique for surface retessellation has been successfully applied to iso-surface models derived from volume data, Connolly surface molecular models and a tessellation of a minimal surface of interest to mathematicians.

summary	The research we will discuss below originated from an attempt to examine the capacity of designers to evaluate an artifact, and to study the feasibility of replicating a designer's moves intended to make an artifact more expressive of a given quality. We will present the results of an interactive computer experiment, first developed at the MIT Design Research Seminar, which is meant to capture the subject’s actions in a simple design task as a series of successive "moves"'. We will propose that designers use metaphors in their interaction with design artifacts and we will argue that the concept of metaphors can lead to a powerful theory of design activity. Finally, we will show how such a theory can drive the project of building a design system. When trying to understand how designers work, it is tempting to examine design products in order to come up with the principles or norms behind them. The problem with such an approach is that it may lead to a purely syntactical analysis of design artifacts, failing to capture the knowledge of the designer in an explicit way, and ignoring the interaction between the designer and the evolving design. We will present a theory about design activity based on the observation that knowledge is brought into play during a design task by a process of interpretation of the design document. By treating an evolving design in terms of the meanings and rules proper to a given way of seeing, a designer can reduce the complexity of a task by focusing on certain of its aspects, and can manipulate abstract elements in a meaningful way.

title	Multiple Operative and Interactive Modes in Knowledge-Based Design Systems
source	New York: John Wiley & Sons, 1992. pp. 125-143 : ill. includes bibliography
summary	A conceptual basis for the development of an expert system which is capable of integrating various modes of generation and evaluation in design is presented. This approach is based upon two sets of reasoning processes in the design system. The first enables a mapping between design requirements and solution descriptions in a generative mode of design; and the second enables a mapping between solution descriptions and performance evaluation in an evaluative and predictive mode. This concept supports a formal framework necessary for a knowledge-based design system to operate in a design partnership relation with the designer. Another fundamental concept in expert systems for design, dual direction interpretation between graphic and textual modes, is presented and elaborated. This encoding of knowledge behind the geometrical representation can be achieved in knowledge- based design systems by the development of a 'semantic interpreter' which supports a dual direction mapping process employing a geometrical knowledge, typological knowledge and evaluative knowledge. An implemented expert system for design, PREDIKT, demonstrates these concepts in the domain of kitchen design. It provides the user with a choice of alternative modes of interaction, such as: a 'design critic' for the evaluation of a design, a 'design generator' for the generation of a design, or a 'design critic-generator' for the completion of partial solutions

title	FULL-SCALE EXPERIMENT ON KITCHEN FUNCTION IN HANOI
source	Proceedings of the 4rd European Full-Scale Modelling Conference / Lausanne (Switzerland) 9-12 September 1992, Part A, pp. 19-30
summary	This study is a part of a licentiate thesis on "Functional kitchen for the Vietnamese cooking way"at the Department of Architecture and Development studies, Lund University. The issues it is dealing with are: (1) Inadequacy of kitchen design in the apartment buildings in Hanoi, where the kitchen is often designed as a mere cooking place - other parts of the food making process are not given any attention. (2) Lack of standard dimensional and planning criteria for functional kitchen which can serve as bases for kitchen design. // The thesis aims at finding out indicators on functional spatial requirements for kitchen, which can serve as guide-line for designing functional kitchen for Hanoi. One of the main propositions in the thesis is that functional kitchens for Hanoi should be organised to permit the culinary activities done according to the Vietnamese urban culinary practice. This is based on the concept that the culinary activity is an expression Of culture, thus the practice of preparing meal in the present context of the urban households in Hanoi has an established pattern, method which demand a suitable area and arrangement in the kitchen. This pattern and cooking method should make up the functional requirement for kitchen in Hanoi, and be taken in to account if functional kitchen designing is to be achieved. In the context of the space-limited apartment building of Hanoi, special focus is given to find out indicators on the minimum functional spatial requirements of the kitchen works.
