title	Practices of Distributed Intelligence and Designs for Education
source	Distributed Cognitions, edited by G. Salomon. New York, NY: CambridgeUniversity Press
summary	v Knowledge is commonly socially constructed, through collaborative efforts... v Intelligence may also be distributed for use in designed artifacts as diverse as physical tools, representations such as diagrams, and computer-user interfaces to complex tasks. v Leont'ev 1978 for activity theory that argues forcibly for the centrality of people-in-action, activity systems, as units of analysis for deepening our understanding of thinking. v Intelligence is distributed: the resources that shape and enable activity are distributed across people, environments, and situations. v Intelligence is accomplished rather than possessed. v Affordance refers to the perceived and actual properties of a thing, primarily those functional properties that determine how the thing could possibly be used. v Norman 1988 on design and psychology - the psychology of everyday things" v We deploy effort-saving strategies in recognition of their cognitive economy and diminished opportunity for error. v The affordances of artifacts may be more or less difficult to convey to novice users of these artifacts in the activities to which they contribute distributed intelligence. v Starts with Norman's seven stages of action Ø Forming a goal; an intention § Task desire - clear goal and intention - an action and a means § Mapping desire - unable to map goal back to action § Circumstantial desire - no specific goal or intention - opportunistic approach to potential new goal § Habitual desire - familiar course of action - rapidly cycle all seven stages of action v Differentiates inscriptional systems from representational or symbol systems because inscriptional systems are completely external, while representational or symbol systems have been used in cognitive science as mental constructs. v The situated properties of everyday cognition are highly inventive in exploiting features of the physical and social situation as resources for performing a task, thereby avoiding the need for mental symbol manipulations unless they are required by that task. v Explicit recognition of the intelligence represented and representable in design, specifically in designed artifacts that play important roles in human activities. v Once intelligence is designed into the affordances properties of artifacts, it both guides and constrains the likely contributions of that artifact to distributed intelligence in activity. v Culturally valued designs for distributed intelligence will change over time, especially as new technology becomes associated with a task domain. v If we treat distributed intelligence in action as the scientific unit of analysis for research and theory on learning and reasoning... Ø What is distributed? Ø What constraints govern the dynamics of such distributions in different time scales? Ø Through what reconfigurations of distributed intelligence might the performance of an activity system improve over time? v Intelligence is manifest in activity and distributed in nature. v Intelligent activities ...in the real world... are often collaborative, depend on resources beyond an individual's long-term memory, and require the use of information-handling tools... v Wartofsky 1979 - the artifact is to cultural evolution what the gene is to biological evolution - the vehicle of information across generations. v Systems of activity - involving persons, environment, tools - become the locus of developmental investigation. v Disagrees with Salomon et al.'s entity-oriented approach - a language of containers holding things. v Human cognition aspires to efficiency in distributing intelligence - across individuals, environment, external symbolic representations, tools, and artifacts - as a means of coping with the complexity of activities we often cal "mental."

title	Decision Support System for Modular Houses

summary	Presently, only a small percentage of people in the world typically hire an architect to design and build a home which is tailored to their preference. Besides the architect’s fee, clients also need to wait an interminable time for design and construction. Factory-made prefabricated housing systems tried to solve this problem previously. However, most pioneers failed to address the issues of variability and individual needs (Kieran & Timberlake, 2004). Plants closed because they produced more than the market demand, and prefabricated housing provided less flexibility than the traditional stick-built housing. The advanced digital technology makes it possible to communicate design ideas and concepts to others more effectively. The project delivery process leads itself to customization, embodying principles of lean production (Pine, 1993), flexible computer-integrated design interaction with clients, and reduced cycle times; all effecting rapid response between consumers and producers.

summary	A review by William J. Mitchell, entitled 'Franchising Architectural Styles", appeared in AA Files no. 26 (Autumn 1993). It reflects on a collision between two fundamentally opposing points of view, one held by the reviewer, the other by the reviewed. These determine our expectations of the role of computers in architectural design.

title	SOME EPISTEMOLOGICAL CONCERNS REGARDING ARTIFICIAL INTELLIGENCE AND KNOWLEDGE-BASED APPROACHES TO ARCHITECTURAL DESIGN - A RENEWED AGENDA
doi	https://doi.org/10.52842/conf.acadia.1993.155
source	Education and Practice: The Critical Interface [ACADIA Conference Proceedings / ISBN 1-880250-02-0] Texas (Texas / USA) 1993, pp. 155-162
summary	It has been noted that designers - when confronted with computers - have, by and large, refused to accept the introduction of apparently new design methodologies, and it has been speculated that this is the result of a failure of those methodologies to address the cognitive processes which take place in the course of designing. This position is somewhat suspect in that such innovations as computer-aided drafting -which also fail to recognize these processes have been widely accepted. It is perhaps more likely that the lack of acceptance results from a perception on the part of designers that the new methodologies either do not reflect some or all of those concerns that designers consider fundamental to design, or that they actively interfere with the designer's ability to accomplish what he/she sees as the goals of design. Given that the application of artificial intelligence and related work to architecture is still in its infancy, all of this suggests the need for a reassessment of the role of computing in design in order to clarify and strengthen those roles deemed appropriate. Two approaches to the integration of artificial intelligence and knowledge-based systems into architectural design practice are currently dominant. One attempts to create systems which can on their own produce designs, the other provides intelligent support for those doing design. It was, in part, the recognition of limitations in the ability of traditional CAD systems and building modelers to reflect what designers actually do that led to explorations into the idea of intelligent assistants. Development of such assistants was aided by research into the act and process of design through protocol and other studies. Although some work is currently being done in the development of artificial intelligence and knowledge based applications in architecture, and work continues to be done on the study of design methodologies, the bulk of available information in each of these areas remains in the realm of design disciplines related to but outside of architecture and do not reflect the explicit role of architectural design in the embodiment and expression of culture. The relationship of intelligence to culture has resulted in some skepticism regarding the ultimate capacity of neural nets and symbolically programmed computers in general. Significant work has been done questioning the rational tradition in computer development for its failure to address phenomena which are not easily subject to scientific analysis. Further skepticism regarding the role of artificial intelligence and knowledge-based or expert systems in architectural design has been emerging recently. Such criticism tends to focus on two issues: the nature of drawing as an activity which involves both the generation and interpretation of graphic artifacts, and the nature of the human designer as an active agent in the design process.

summary	Creativity is an important factor for innovators. According to Eguchi and Pinheiro (2008) the basis of design is innovation because of the use creative methodology. It’s important to remember that the word “project” comes from the Latin “proyectus”, meaning “a forward throwing action”. According to Ramos (2006), “educating for creativity is essential.” Beetlestone (2000), De Bono (1993), Munari (1997) and Pawlak (2000) argue that as we’re children we’re curious to find answers to everything, but that traditional schooling brakes the creativity. This research is a methodological test which aims to identify the reasons for student’s selection of specific creative tools used in university projects.

title	Design communication and image processing
source	Architectural and Urban Simulation Techniques in Research and Education [Proceedings of the 3rd European Architectural Endoscopy Association Conference / ISBN 90-407-1669-2]
summary	In the proceedings of the first EAEA conference, 1993, I mentioned our first study focused on refining endoscopic video images of a detailed architectural model and drawings. The study was based on work with 900 subjects, of which 200 were professional architects. It has led to a number of technical improvements. In the second study we compared computer-aided design techniques with two techniques from the first study, endoscopic video recordings and coloured and black and white elevations and perspective drawings. Four different groups of 50 subjects took part in this research. We found that computer images are invariably judged to be of moderate value, while drawings yielded consistently high scores. Endoscopic video recordings of the scale model received high scores as far as emotional response is concerned, and moderate scores when the participants were questioned on the actual content of the recordings.

title	Simultaneous Form Generation and Performance Evaluation: A "Two-Way" Inference Approach
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 161-173
summary	The conventional approach toward performance evaluation transforms given design attributes into performance indicators, and designers can improve these indicators only indirectly through the manipulation of design attributes. This paper outlines a contrasting "two-way " inference approach that allows designers to also manipulate the performance indicators directly and observe the resulting changes in design attributes. The advantages of this approach and its limitations are outlined. Methodological and implementation difficulties that arise from it are introduced, and possible solution strategies are described. A first prototype for a system that implements and demonstrates this approach is outlined. The larger debate about 'functionalism " touched by this approach, and its response to it, are briefly reviewed.

title	Introducing 2D Draughting and 3D CAD Modelling into the Information and Library Studies Curriculum in Response to Increasingly Complex Design Requirements of Information Resources
doi	https://doi.org/10.52842/conf.ecaade.1993.x.q0e
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	This paper describes enhancements to the Information and Library Studies curriculum at the Liverpool John Moores University. In the design process for buildings and space utilised for learning resources informed client involvement is seen as important by the information professional. A new module has been introduced with the aim of providing students with the knowledge and skills to communicate effectively with building design professionals. It is apparent that CAD has a place in this teaching. The programme of study is outlined, including a discussion of significant, relevant examples produced by the CAAD staff of the School of the Built Environment. The teaching methods were drawn from experience in the well established curricula and delivery of CAAD to the architecture and environmental planning students using School of the Built Environment Macintosh hardware and software. From the Aldham Robarts Learning Resource Centre, (presently nearing completion) examples will be shown of animated models, design, organisational and staffing solutions to new technological demands. These include transfer of the Austin - Smith: Lord Intergraph/MicroStation 3D model to Zoom, animation with Electric Image and Theseus and assisting library staff to use ArchiCAD to design and consider shelf planning arrangements for negotiation with the architects. There are interesting lessons to be learned about the advantages of CAD for future client control.

title	Mapping a Single Data Stream to Multiple Auditory Variables: A Subjective Approach to Creating a Compelling Design
source	Proceedings of the Third International Conferenceon Auditory Display, Santa FO Institute
summary	Representing a single data variable changing in time via sonification, or using that data to control a sound in some way appears to be a simple problem but actually involves a significant degree of subjectivity. This paper is a response to my own focus on specific sonification tasks (Kramer 1990, 1993) (Fitch & Kramer, 1994), on broad theoretical concerns in auditory display (Kramer 1994a, 1994b, 1995), and on the representation of high-dimensional data sets (Kramer 1991a & Kramer & Ellison, 1991b). The design focus of this paper is partly a response to the others who, like myself, have primarily employed single fundamental acoustic variables such as pitch or loudness to represent single data streams. These simple representations have framed three challenges: Behavioral and Cognitive Science-Can sonifications created with complex sounds changing simultaneously in several dimensions facilitate the formation of a stronger internal auditory image, or audiation, than would be produced by simpler sonifications? Human Factors and Applications-Would such a stronger internal image of the data prove to be more useful from the standpoint of conveying information? Technology and Design-How might these richer displays be constructed? This final question serves as a starting point for this paper. After years of cautious sonification research I wanted to explore the creation of more interesting and compelling representations.

title	Measuring the effect of attention on simple visual search
source	Journal of Experimental Psychology: Human Perception and Performance 19(1) 108-130.
summary	It is unclear to what extent attention affects perception rather than memory and decision. Is all of perception limited by attention, or is perception completely preattentive, and attention only affects memory and decision, or some compromise? The answer is in your definitions of these phenomena. Visual search task: display set size The display set size increases response time and/or response accuracy. This is a putative example of divided attention in the literature. The goal of this paper is to be more rigorous in studying this setsize phenomena, and try and decouple attention on perception Display set size: The total number of stimuli in an experiment. Relevant set size: Total number of 'cued' stimuli in an experiment.

title	A Better Understanding of The Role of Endoscopy as a Tool in Architecture
source	Endoscopy as a Tool in Architecture [Proceedings of the 1st European Architectural Endoscopy Association Conference / ISBN 951-722-069-3] Tampere (Finland), 25-28 August 1993, pp. 123-128
summary	As the most tool-dependent species on our planet, our technology determines our activities and thus defines our existence. Because of this a clear understanding of the ends-means relationship of our tools is of critical social- and professional-concern. Endoscopy, or the use of periscopic-like devices to extract human eye-level visual images, static or dynamic, from iconic scale models of proposed environments, is a case in point. Use is appropriate at advanced stages of planning and design, when such experiential simulations are necessary for both professional evaluation and lay approval. But note that the simulation is only a means to an end, and that the fundamental purpose is to evoke a response to a proposal. Simulation and response are opposite sides of the same coin, and the response is the goal. Any such responses are meaningful only with reference to the ultimate users’ experiential preferences, preferably explicitly established as ”performance specifications” before the start of the design process in consultation with a representative sample of these people. This implies the necessity of a means to identify these beneficiaries of our work, and a means to characterize their environmental ”experiential profiles”. It also requires a means for the discursive scripting of their experiential preferences. The development of a design oriented to the achievement of these ends then depends on a similar time-based scoring for the description of sequentially-experienced environmental attributes, hypothesized as related to these responses. Endoscopy then takes its place as the means for a penultimate check on the experiential design-hypotheses, in conjunction with suitable means to record the simulates’ responses in the same format as the original experiential performance specifications, for comparison therewith. The danger in being the most tool-dependent species on Earth is that in our necessary concern with technological means we may loose sight of our ultimate human ends; as suggested by the apothegm ”the operation was a success, but the patient died”. Our inexorable impetus toward technological development means that the specialized training that is inherent in professional education tends to separate and distance the perceptions of those so conditioned from those of the many others who are the presumed beneficiaries of their efforts.

title	A Tool for Typological Analysis
doi	https://doi.org/10.52842/conf.ecaade.1993.x.q0g
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	Any design problem is faced drawing from the architect's knowledge both case knowledge and general knowledge. One type of the latter is abstracted from a multiplicity of cases of which the common features are recognised in such a way as to single out a prototype representing in the best way a class of architectural objects. If applied to a set of residential buildings and to the flats in them the analysis is typological and it is one of the fundamental ways of acquiring general knowledge to be used to face design problems. The tool we present is aimed at such a type of analysis and is based on the idea that it possible to acquire qualitative knowledge through the statistical analysis of measurable characteristics of the examined architectural objects. It has been tested by applying it to the typological analysis of a set of flats of illegal buildings in Sicily. The procedure is organised in two main phases. The first one consists in a series of elaborations performed during the reading of architectural organism; the second one consists in a series of statistical analyses on the results (characteristic variables) of the first.

summary	The European Architectural Endoscopy Association was established in connection with the Association’s first international conference on August 25-28, 1993, which was hosted by the Department of Architecture at the Tampere University of Technology. The purpose of the EAEA is to promote experimentation, research, communication, exchange of experiences, collaboration, user participation and teaching in the field of endoscopy and environmental simulation. The first EAEA conference was attended by 25 people from 15 different universities. Working under the general heading of “Endoscopy as a Tool in Architecture”, the conference had three specific themes for the first three days: Review of Existing Laboratories; Theories, Methods and Applications; and the Future of Endoscopy. In this volume we have compiled all the papers that were presented at the conference. The texts have been printed in the form we received them, without any attempt to edit them for consistency in style, adding hopefully to a sense of authenticity. Unfortunately, the impressive videos we saw at the conference on the possibilities of endoscopy and environmental simulation as a tool in architecture, cannot be documented here.

summary	The Olympus Optical Company of Japan was formed in 1919, with the introduction of the first generation single lens reflects camera, and soon after with the first microscope. Since that time, the organisation has developed and is now split into three main divisions: manufacturing and supplying cameras, microscopes and endoscopes. Other smaller specialist divisions exist suppling such products as dictaphones. Perhaps, rather surprisingly, the endoscope division is the largest part of the organisation. Through a world-wide organisation of four main business centers, Olympus Industrial, the name given to the industrial endoscope division, provides service and support to its customers. Each of the main business centers operates through agents and distributors. There are many different industries which gain the benefits of saved time and money provided by using endoscopes. To meet the needs of so many varied industries, there is a need to have a wide range of equipment. This includes light sources, to provide illumination, rigid borescopes, flexible fiberscopes, if views around corners are needed, and the new technology videoscopes. These instruments use the latest CCD technology with a small chip situated in the distal end of the scope, instead of fiberoptic image bundles used in fiberscopes.

title	Designing the Future: The Computer Transformation of Reality
source	Thames and Hudson, Hong Kong
summary	A coffee table book on computer applications? Well, yes, because it does deal largely with matters of graphic design in architecture, fashion and textiles, painting, and photography; but it also has items which might be of interest in its sections on digital publication, typography, and electronic communication in general. It also seeks to discuss the way in which these applications may force us to change the way we think. Robin Baker writes in an unfortunately stiff and abstract manner about the impact computer programmes have had on the world of art and design, but the graphic images and extended picture captions help to keep the reader awake - even though the main text sometimes disappears for two or three double page spreads on end. There are also smatterings of pretentious art-world-speak about 'solving certain spatial problems' (in the design of curtain fabrics or teapots) and the introduction (inevitable?) of new jargon: 'shape grammar'(a list of so-called shape 'rules'), 'repurposing' (putting somebody else's work to new use) and 'genetic algorithms' (sculptural designs based on re-processed organic shapes - most of which look like stomach tumours). In his favour, Baker very generously credits students and commercial designers who have produced the effects he describes and illustrates so well. For writers, he sketches in the possibilities of Hypertext and Hypermedia and points to the future of Hyper publishing which he (and Rupert Murdoch)believes will be with us before the end of the century. He seems to have a good oversight of what is possible and practicable - though one wonders how up-to-date the view is when his book may have begun its life anything up to three years ago. He usefully points out that much new technology exists in or drags along with it the forms of earlier periods - so that in an age of electronic communication we still have printed books as a dominant cultural form. Maybe this is as it should be - but Baker makes a persuasive case for the claim that All This is Going to Change.

title	Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 181-200.
summary	The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

summary	Advanced computer-aided architectural applications must model buildings as multi-level compositions supporting distinct points of view. Hierarchies of encapsulated, autonomous elements can be derived from ISO-STEP's General AEC Reference Model and configured for various applications. For analysis of life-cycle costs, we define a Pyramid of evaluable production steps leading to the final building; for optimization of renovation task schedules, a topological model of access paths and traffic flow. These separate viewpoints can be embedded in a single unifying structure permitting the communication and propagation of changes among its specialized aspects.

summary	This paper addresses communication issues, which are crucial in any implementation of distributed design environments. Communication needs are specified and implemented in a prototype based on a modular knowledge-based approach for simulation of a distributed multi-user system. The results of these simulations are reported, which show communication to be scalable as the numbers of applications and the size of the design increases. Finally, the implications of the results on real distributed systems are discussed.

summary	Current interfaces and help facilities of CAD systems are not designed to respond to a user's performance. To develop such adaptive environments, a better understanding of the indicators of CAD experience is required. This paper discusses the results of studying behavior patterns of different types and levels of CAD users for a specific drawing task. The results show that the type and experience of the CAD user has a clear correlation to the pattern of commands used, the time taken, and the quality of drawing produced. By using the experimental data to train a neural network, the paper demonstrates a connectionist approach for experience assessment. This information, it is proposed, can provide input to an adaptive interface which generates unobtrusive interception to improve the performance of a CAD user. Future experiments to explore the issues of generality and interception are presented.

summary	Jaron Lanier is a major spokesperson of our society's hottest new technology: VR or virtual reality. He expressed his faith in the VR movement in this quote which appears in The User's Guide to the New Edge published by Mondo 2000. In its most technical sense, VR has attracted the attention of politicians in Washington who wonder if yet another technology developed in the United States will find its application across the globe in Asia. In its most human element, an entire "cyberpunk movement" has appealed to young minds everywhere as a seemingly safe form of hallucination. As architecture students, educators, and practitioners around the world are becoming attracted to the possibilities of VR technology as an extension of 3D modeling, visualization, and animation, it is appropriate to consider an overview of virtual reality. In virtual reality a user encounters a computersimulated environment through the use of a physical interface. The user can interact with the environment to the point of becoming a part of the experience, and the experience becomes reality. Natural and instinctive body movements are translated by the interface into computer commands. The quest for perfection in this human-computer relationship seems to be the essence of virtual reality technology. To begin to capture the essence of virtual reality without first-hand experience, it is helpful to understand two important terms: presence and immersion. The sense of presence can be defined as the degree to which the user feels a part of the actual environment. The more reality the experience provides, the more presence it has. Immersion can be defined as the degree of other simulation a virtual reality interface provides for the viewer. A highly immersive system might provide more than just visual stimuli; for example, it may additionally provide simulated sound and motion, and simultaneously prevent distractions from being present.
