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 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 The comparison of animation, virtual reality, and scenario scripting in design process
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 Design media is a fundamental tool, which can incubate concrete ideas from ambiguous concepts. Evolved from freehand sketches, physical models to computerized drafting, modeling (Dave, 2000), animations (Woo, et al., 1999), and virtual reality (Chiu, 1999; Klercker, 1999; Emdanat, 1999), different media are used to communicate to designers or users with different conceptual levels¡@during the design process. Extensively employed in design process, physical models help designers in managing forms and spaces more precisely and more freely (Millon, 1994; Liu, 1996).Computerized drafting, models, animations, and VR have gradually replaced conventional media, freehand sketches and physical models. Diversely used in the design process, computerized media allow designers to handle more divergent levels of space than conventional media do. The rapid emergence of computers in design process has ushered in efforts to the visual impact of this media, particularly (Rahman, 1992). He also emphasized the use of computerized media: modeling and animations. Moreover, based on Rahman's study, Bai and Liu (1998) applied a new design media¡Xvirtual reality, to the design process. In doing so, they proposed an evaluation process to examine the visual impact of this new media in the design process. That same investigation pointed towards the facilitative role of the computerized media in enhancing topical comprehension, concept realization, and development of ideas.Computer technology fosters the growth of emerging media. A new computerized media, scenario scripting (Sasada, 2000; Jozen, 2000), markedly enhances computer animations and, in doing so, positively impacts design processes. For the three latest media, i.e., computerized animation, virtual reality, and scenario scripting, the following question arises: What role does visual impact play in different design phases of these media. Moreover, what is the origin of such an impact? Furthermore, what are the similarities and variances of computing techniques, principles of interaction, and practical applications among these computerized media?This study investigates the similarities and variances among computing techniques, interacting principles, and their applications in the above three media. Different computerized media in the design process are also adopted to explore related phenomenon by using these three media in two projects. First, a renewal planning project of the old district of Hsinchu City is inspected, in which animations and scenario scripting are used. Second, the renewal project is compared with a progressive design project for the Hsinchu Digital Museum, as designed by Peter Eisenman. Finally, similarity and variance among these computerized media are discussed.This study also examines the visual impact of these three computerized media in the design process. In computerized animation, although other designers can realize the spatial concept in design, users cannot fully comprehend the concept. On the other hand, other media such as virtual reality and scenario scripting enable users to more directly comprehend what the designer's presentation.Future studies should more closely examine how these three media impact the design process. This study not only provides further insight into the fundamental characteristics of the three computerized media discussed herein, but also enables designers to adopt different media in the design stages. Both designers and users can more fully understand design-related concepts.

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 Systems Thinking, Systems Practice

summary Whether by design, accident or merely synchronicity, Checkland appears to have developed a habit of writing seminal publications near the start of each decade which establish the basis and framework for systems methodology research for that decade."" Hamish Rennie, Journal of the Operational Research Society, 1992 Thirty years ago Peter Checkland set out to test whether the Systems Engineering (SE) approach, highly successful in technical problems, could be used by managers coping with the unfolding complexities of organizational life. The straightforward transfer of SE to the broader situations of management was not possible, but by insisting on a combination of systems thinking strongly linked to real-world practice Checkland and his collaborators developed an alternative approach - Soft Systems Methodology (SSM) - which enables managers of all kinds and at any level to deal with the subtleties and confusions of the situations they face. This work established the now accepted distinction between hard systems thinking, in which parts of the world are taken to be systems which can be engineered, and soft systems thinking in which the focus is on making sure the process of inquiry into real-world complexity is itself a system for learning. Systems Thinking, Systems Practice (1981) and Soft Systems Methodology in Action (1990) together with an earlier paper Towards a Systems-based Methodology for Real-World Problem Solving (1972) have long been recognized as classics in the field. Now Peter Checkland has looked back over the three decades of SSM development, brought the account of it up to date, and reflected on the whole evolutionary process which has produced a mature SSM. SSM: A 30-Year Retrospective, here included with Systems Thinking, Systems Practice closes a chapter on what is undoubtedly the most significant single research programme on the use of systems ideas in problem solving. Now retired from full-time university work, Peter Checkland continues his research as a Leverhulme Emeritus Fellow. "

summary Teaching the use of computers in architecture poses the same kind of problems as teaching mathematics. To both there are two possible approaches. The first presents the discipline as a tool of which the merely instrumental aspect is emphasized. Teaching is limited to show the results obtainable by existing programs and how to get them. The second approach, on the contrary emphasizes the autonomous nature of the discipline, mathematics as much as computing, on the basis of the convincement that the maximum of instrumental usefulness can be obtained through the knowledge at the highest degree of generality and, then, of abstraction. The first approach changes little in the mind of the student. He simply learns that is possible, and then worthy doing, a certain amount of operations, mainly checks of performances (and not only the control of the aspect, now easy with one of the many existing CAD) or searches of technical informations in some database. The second approach gives the student the consciousness of the manageability of abstract structures of relationships. He acquires then the idea of creating by himself particular structures of relationships and managing them. This can modify the very idea of the design procedure giving the student the consciousness that he can intervene directly in every segment of the design procedure, reshaping it to some extent in a way better suited to the particular problem he is dealing with. Of course this second approach implies learning not only a language but also the capability of coming to terms with languages. And again it is a cultural acquisition that can be very useful when referred to the languages of architecture. Furthermore the capability of simulating on the computer also a small segment of the design process gives the student a better understanding both of the particular problem he is dealing with and of the very nature of design. As for the first effect, it happens whenever a translation is done from a language to another one. One is obliged to get to the core of the matter in order to overcome the difficulties rising from the different bias of the two languages. The second effect comes from the necessity of placing the studied segment in the general flow of the design process. The organisation in a linear sequence of action to be accomplished recursively in an order always varying in any design occasion is an extremely useful exercise to understand the signification and the techniques of formalisation of design problems.

summary Normative and problem-solving approaches of architectural design ignore the personality aspects of the designing activity. Every architect approaches projects according to her/his own strategies and tactics. Usually they do not conform to the prescriptive models of design theoreticians. Computer aided design tools should be adapted to their utility within the strategies and tactics of each and every architectural student. We are testing the usefulness of CAAD tools developed by others or ourselves and identifying the needs for missing tools. It is already clear that many CAAD tools reflect the point of view of the programmer about strategies and tactics of designing and that they do not take into account the idiosyncrasies of the end user. Forcing the tools on students breeds the risk of fostering repulsion against ill-adapted tools, and consequently against CMD. Our research group pursues empirical research on working styles of designing by practising architects within the frame of a personality theory of actions. The results indicate that there are three main directions for designing strategies. If we want to take into account the real-world behaviour in design practice within architectural education, this implies the diversification of the exercises we offer to the students in threefold, corresponding with the three directions. To this, we add the didactic options of complementation, compensation and support, depending on what we know about the strong or weak points of the students involved. We have started proposing choices for the exercises of our design morphology studio. Students are offered approaches and tools we consider best adapted to their own working

title SEED: A Software Environment to Support the Early Phases in Building Design
source Proceeding of IKM '94, Weimar, Germany, pp. 5-10
summary The SEED project intends to develop a software environment that supports the early phases in building design (Flemming et al., 1993). The goal is to provide support, in principle, for the preliminary design of buildings in all aspects that can gain from computer support. This includes using the computer not only for analysis and evaluation, but also more actively for the generation of designs, or more accurately, for the rapid generation of design representations. A major motivation for the development of SEED is to bring the results of two multi-generational research efforts focusing on `generative' design systems closer to practice: 1. LOOS/ABLOOS, a generative system for the synthesis of layouts of rectangles (Flemming et al., 1988; Flemming, 1989; Coyne and Flemming, 1990; Coyne, 1991); 2. GENESIS, a rule-based system that supports the generation of assemblies of 3-dimensional solids (Heisserman, 1991; Heisserman and Woodbury, 1993). The rapid generation of design representations can take advantage of special opportunities when it deals with a recurring building type, that is, a building type dealt with frequently by the users of the system. Design firms - from housing manufacturers to government agencies - accumulate considerable experience with recurring building types. But current CAD systems capture this experience and support its reuse only marginally. SEED intends to provide systematic support for the storing and retrieval of past solutions and their adaptation to similar problem situations. This motivation aligns aspects of SEED closely with current work in Artificial Intelligence that focuses on case-based design (see, for example, Kolodner, 1991; Domeshek and Kolodner, 1992; Hua et al., 1992).

title A decision-making process for choice of a flexible internal partition option in multi-unit housing using decision theory techniques
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 Recent demographic changes have increased the heterogeneity of user groups in the North American housing market. Smaller households (e.g. elderly, single parent) have non-traditional spatial requirements that cannot be accommodated within the conventional house layout. This has created renewed interest in Demountable/Flexible internal partition systems. However, the process by which designers decide which project or user groups are most suited for the use of these systems is quite often complex, non-linear, uncertain and dynamic, since the decisions involve natural processes and human values that are apparently random. The anonymity of users when mass housing projects are conceptualized, and the uncertainty as to the alternative to be selected by the user, given his/her constantly changing needs, are some contributing factors to this effect. Decision Theory techniques, not commonly used by architects, can facilitate the decision-making process through a systematic evaluation of alternatives by means of quantitative methods in order to reduce uncertainty in probabilistic events or in cases when data is insufficient. The author used Decision Theory in the selection of flexible partition systems. The study involved a multi-unit, privately initiated housing project in Montreal, Canada, where real site conditions and costs were used. In this paper, the author outlines the fundamentals of Decision Theory and demonstrates the use of Expected Monetary Value and Weighted Objective Analysis methods and their outcomes in the design of a Montreal housing project. The study showed that Decision Theory can be used as an effective tool in housing design once the designer knows how to collect basic data.

summary We studied CAD system users to find out how they use the sophisticated customization and extension facilities offered by many CAD products. We found that users of varying levels of expertise collaborate to customize their CAD environments and to create programmatic extensions to their applications. Within a group of users, there is at least one local expert who provides support for other users. We call this person a local developer. The local developer is a fellow domain expert, not a professional programmer, outside technical consultant or MIS staff member. We found that in some CAD environments the support role has been formalized so that local developers are given official recognition, and time and resources to pursue local developer activities. In general, this formalization of the local developer role appears successful. We discuss the implications of our findings for work practices and for software design.

title On the Limitations of Shape Grammars: Comments on Aaron Fleisher’s Article “Grammatical Architecture?”
source Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 279-287
doi https://doi.org/10.52842/conf.acadia.2003.279
summary Shape grammars were introduced by Gips and Stiny in 1972. Since then, there have been many articles and books written by them and their associates. In 1992, Aaron Fleisher, a professor at the School of Planning, MIT, wrote a critique of their work in an article titled “Grammatical Architecture?” published in the journal Environment and Planning B. According to him, Gips, Stiny and later Mitchell, propose a hypothesis that states that shape grammars are presumed to represent knowledge of architectural form, that grammars are “formable,” and that there is a visual correspondence to verbal grammar. The strong version of “the hypothesis requires that an architectural form be equivalent to a grammar.” Fleisher considers these hypotheses unsustainable, and argues his case by analyzing the differences between language, and architecture, and by dealing with the concepts of lexicons, syntax and semantics. He concludes by stating that architectural design is negotiated in two modalities: the verbal and the visual, and that equivalences are not at issue; they do not exist. If there is such thing as a language for design, it would provide the means to maintain a discussion of the consequences in one mode, of the state and conditions of the other. Fleisher’s observations serve as the basis of this paper, a tribute to him, and also an opportunity to present an outline to an alternate approach or hypothesis to shape grammars, which is “nonlinguistic” but “generative,” in the sense that it uses production rules. A basic aspect of this hypothesis is that the only similarity between syntactic rules in language and some rules in architecture is that they are recursive.

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 Genetic Algorithms
source Scientific America, July 1992
summary Living organisms are consummate problem solvers. They exhibit a versatility that puts the best computer programs to shame. This observation is especially galling for computer scientists, who may spend months or years of intellectual effort on an algorithm, whereas organisms come by their abilities through the apparently undirected mechanism of evolution and natural selection. Pragmatic researchers see evolution's remarkable power as something to be emulated rather than envied. Natural selection eliminates one of the greatest hurdles in software design: specifying in advance all the features of a problem and the actions a program should take to deal with them. By harnessing the mechanisms of evolution, researchers may be able to "breed" programs that solve problems even when no person can fully understand their structure. Indeed, these so-called genetic algorithms have already demonstrated the ability to made breakthroughs in the design of such complex systems as jet engines. Genetic algorithms make it possible to explore a far greater range of potential solutions to a problem than do conventional programs. Furthermore, as researchers probe the natural selection of programs under controlled an well-understood conditions, the practical results they achieve may yield some insight into the details of how life and intelligence evolve in the natural world.

title A FRAMEWORK FOR COMPUTER-SUPPORTED COLLABORATION IN ARCHITECTURAL DESIGN
source University of Michigan
summary The development of appropriate research frameworks and guidelines for the construction of software aids in the area of architectural design can lead to a better understanding of designing and computer support for designing (Gero and Maher 1997). The field of research and development in computer-supported collaborative architectural design reflects that of the early period in the development of the field of computersupported cooperative work (CSCW). In the early 1990s, the field of CSCW relied on unsystematic attempts to generate software that increases the productivity of people working together (Robinson 1992). Furthermore, a shift is taking place by which researchers in the field of architecture are increasingly becoming consumers of rather than innovators of technology (Gero and Maher . In particular, the field of architecture is rapidly becoming dependent on commercial software implementations that are slow to respond to new research or to user demands. Additionally, these commercial systems force a particular view of the domain they serve and as such might hinder rather than help its development. The aim of this dissertation is to provide information to architects and others to help them build their own tools or, at a minimum, be critical of commercial solutions.

title How Can We Achieve a Good Building?
source New York: John Wiley & Sons, 1992. pp. 51-65 : ill. includes bibliography
summary This paper is concerned with the reasons and purposes for which we evaluate and predict building performance. The discussion is based on the author's experience, gained through the preparation and evaluation of more than 50 major architectural competitions
keywords An attempt is made to discover for whom and in what respect a building can be considered a 'good building,' by asking the following questions: What can prediction and evaluation of building performance achieve? How well can we assess the performance and value of an existing building within its socio-technical context? For what purposes and with what degree of confidence can the eventual performance of a designed and specified building be predicted? How do these evaluations compare to actual post occupancy performance? To what extent do the roles and motivations of assessors, evaluators, and decision makers affect the value-stating process? prediction, evaluation, performance, building, life cycle, design, architecture

summary Computer Applications in Architecture is emerging as an important aspect of our profession. The field, which is often referred to as Computer-Aided Architectural Design (CAAD) has had a notable impact on the profession and academia in recent years. A few professionals have predicted that as slide rules were replaced by calculators, in the coming years drafting boards and parallel bars will be replaced by computers. On the other hand, many architects do not anticipate such a drastic change in the coming decade as present CAD systems are supporting only a few integral aspects of architectural design. However, all agree that architecture curricula should be modified to integrate CAAD education.

In 1992-93, in the Department of Architecture of the 'School of Architecture and interior Design' at the University of Cincinnati, a curriculum committee was formed to review and modify the entire architecture curriculum. Since our profession and academia relate directly to each other, the author felt that while revising the curriculum, the committee should have factual information about CAD usage in the industry. Three ways to obtain such information were thought of, namely (1) conducting person to person or telephone interviews with the practitioners (2) requesting firms to give open- ended feed back and (3) surveying firms by sending a questionnaire. Of these three, the most effective, efficient and suitable method to obtain such information was an organized survey through a questionnaire. In mid December 1992, a survey was organized which was sponsored by the School of Architecture and Interior Design, the Center for the Study of the Practice of Architecture (CSPA) and the University Division of Professional Practice, all from the University of Cincinnati.

This chapter focuses on the results of this survey. A brief description of the survey design is also given. In the next section a few surveys organized in recent years are listed. In the third section the design of this survey is presented. The survey questions and their responses are given in the fourth section. The last section presents the conclusions and brief recommendations regarding computer curriculum in architecture.

title Evaluation of Designs for Energy Performance Using A Knowledge-Based System
source New York: John Wiley & Sons, 1992. pp. 293-304 : ill. includes a bibliography
summary Principles of knowledge-based (or expert) systems have been applied in different knowledge-rich domains such as geology, medicine, and very large scale integrated circuits (VLSI). There have been some efforts to develop expert systems for evaluation and prediction of architectural designs in this decade. This paper presents a prototype system, Energy Expert, which quickly computes the approximate yearly energy performance of a building design, analyzes the energy performance, and gives advice on possible ways of improving the design. These modifications are intended to make the building more energy efficient and help cut down on heating and cooling costs. The system is designed for the schematic design phase of an architectural project. Also discussed briefly is the reasoning behind developing such a system for the schematic design rather than the final design phase

summary The introduction of VRML (Virtual Reality Markup Language) in 1994, and other similar web-enabled dynamic modeling software (such as SGI’s Open Inventor and WebSpace), have created a rush to develop on-line 3D virtual environments, with purposes ranging from art, to entertainment, to shopping, to culture and education. Some developers took their cues from the science fiction literature of Gibson (1984), Stephenson (1992), and others. Many were web-extensions to single-player video games. But most were created as a direct extension to our new-found ability to digitally model 3D spaces and to endow them with interactive control and pseudo-inhabitation. Surprisingly, this technologically-driven stampede paid little attention to the core principles of place-making and presence, derived from architecture and cognitive science, respectively: two principles that could and should inform the essence of the virtual place experience and help steer its development. Why are the principles of place-making and presence important for the development of virtual environments? Why not simply be content with our ability to create realistically-looking 3D worlds that we can visit remotely? What could we possibly learn about making these worlds better, had we understood the essence of place and presence? To answer these questions we cannot look at place-making (both physical and virtual) from a 3D space-making point of view alone, because places are not an end unto themselves. Rather, places must be considered a locus of contextualization and embodiment that ground human activities and give them meaning. In doing so, places acquire a meaning of their own, which facilitates, improves, and enriches many aspects of our lives. They provide us with a means to interpret the activities of others and to direct our own actions. Such meaning is comprised of the social and cultural conceptions and behaviors imprinted on the environment by the presence and activities of its inhabitants, who in turn, ‘read’ by them through their own corporeal embodiment of the same environment. This transactional relationship between the physical aspects of an environment, its social/cultural context, and our own embodiment of it, combine to create what is known as a sense of place: the psychological, physical, social, and cultural framework that helps us interpret the world around us, and directs our own behavior in it. In turn, it is our own (as well as others’) presence in that environment that gives it meaning, and shapes its social/cultural character. By understanding the essence of place-ness in general, and in cyberspace in particular, we can create virtual places that can better support Internet-based activities, and make them equal to, in some cases even better than their physical counterparts. One of the activities that stands to benefit most from understanding the concept of cyber-places is learning—an interpersonal activity that requires the co-presence of others (a teacher and/or fellow learners), who can point out the difference between what matters and what does not, and produce an emotional involvement that helps students learn. Thus, while many administrators and educators rush to develop webbased remote learning sites, to leverage the economic advantages of one-tomany learning modalities, these sites deprive learners of the contextualization and embodiment inherent in brick-and-mortar learning institutions, and which are needed to support the activity of learning. Can these qualities be achieved in virtual learning environments? If so, how? These are some of the questions this talk will try to answer by presenting a virtual place-making methodology and its experimental implementation, intended to create a sense of place through contextualization and embodiment in virtual learning environments.

title Design Knowledge, Environmental Complexity in Nonorthogonal Space
source New York: John Wiley & Sons, 1992. pp. 273-291 : ill. includes bibliography
summary Mechanization and industrialization of society has resulted in most people spending the greater part of their lives in enclosed environments. Optimal design of indoor artificial climates is therefore of increasing importance. Wherever artificial climates are created for human occupation, the aim is that the environment be designed so that individuals are in thermal comfort. Current design methodologies for radiant panel heating systems do not adequately account for the complexities of human thermal comfort, because they monitor air temperature alone and do not account for thermal neutrality in complex enclosures. Thermal comfort for a person is defined as that condition of mind which expresses satisfaction with the thermal environment. Thermal comfort is dependent on Mean Radiant Temperature and Operative Temperature among other factors. In designing artificial climates for human occupancy the interaction of the human with the heated surfaces as well the surface-to-surface heat exchange must be accounted for. Early work in the area provided an elaborate and difficult method for calculating radiant heat exchange for simplistic and orthogonal enclosures. A new improved method developed by the authors for designing radiant panel heating systems based on human thermal comfort and mean radiant temperature is presented. Through automation and elaboration this method overcomes the limitations of the early work. The design procedure accounts for human thermal comfort in nonorthogonal as well as orthogonal spaces based on mean radiant temperature prediction. The limitation of simplistic orthogonal geometries has been overcome with the introduction of the MRT-Correction method and inclined surface-to-person shape factor methodology. The new design method increases the accuracy of calculation and prediction of human thermal comfort and will allow designers to simulate complex enclosures utilizing the latest design knowledge of radiant heat exchange to increase human thermal comfort
