title	Predicting the Past, Remembering the Future
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 2-3
summary	Charlas Magistrales 2There never has been such an exciting moment in time in the extraordinary 30 year history of our subject area, as NOW,when the philosophical theoretical and practical issues of virtuality are taking centre stage.The PastThere have, of course, been other defining moments during these exciting 30 years:• the first algorithms for generating building layouts (circa 1965).• the first use of Computer graphics for building appraisal (circa 1966).• the first integrated package for building performance appraisal (circa 1972).• the first computer generated perspective drawings (circa 1973).• the first robust drafting systems (circa 1975).• the first dynamic energy models (circa 1982).• the first photorealistic colour imaging (circa 1986).• the first animations (circa 1988)• the first multimedia systems (circa 1995), and• the first convincing demonstrations of virtual reality (circa 1996).Whereas the CAAD community has been hugely inventive in the development of ICT applications to building design, it hasbeen woefully remiss in its attempts to evaluate the contribution of those developments to the quality of the built environmentor to the efficiency of the design process. In the absence of any real evidence, one can only conjecture regarding the realbenefits which fall, it is suggested, under the following headings:• Verisimilitude: The extraordinary quality of still and animated images of the formal qualities of the interiors and exteriorsof individual buildings and of whole neighborhoods must surely give great comfort to practitioners and their clients thatwhat is intended, formally, is what will be delivered, i.e. WYSIWYG - what you see is what you get.• Sustainability: The power of «first-principle» models of the dynamic energetic behaviour of buildings in response tochanging diurnal and seasonal conditions has the potential to save millions of dollars and dramatically to reduce thedamaging environmental pollution created by badly designed and managed buildings.• Productivity: CAD is now a multi-billion dollar business which offers design decision support systems which operate,effectively, across continents, time-zones, professions and companies.• Communication: Multi-media technology - cheap to deliver but high in value - is changing the way in which we canexplain and understand the past and, envisage and anticipate the future; virtual past and virtual future!MacromyopiaThe late John Lansdown offered the view, in his wonderfully prophetic way, that ...”the future will be just like the past, onlymore so...”So what can we expect the extraordinary trajectory of our subject area to be?To have any chance of being accurate we have to have an understanding of the phenomenon of macromyopia: thephenomenon exhibitted by society of greatly exaggerating the immediate short-term impact of new technologies (particularlythe information technologies) but, more importantly, seriously underestimating their sustained long-term impacts - socially,economically and intellectually . Examples of flawed predictions regarding the the future application of information technologiesinclude:• The British Government in 1880 declined to support the idea of a national telephonic system, backed by the argumentthat there were sufficient small boys in the countryside to run with messages.• Alexander Bell was modest enough to say that: «I am not boasting or exaggerating but I believe, one day, there will bea telephone in every American city».• Tom Watson, in 1943 said: «I think there is a world market for about 5 computers».• In 1977, Ken Olssop of Digital said: «There is no reason for any individuals to have a computer in their home».The FutureJust as the ascent of woman/man-kind can be attributed to her/his capacity to discover amplifiers of the modest humancapability, so we shall discover how best to exploit our most important amplifier - that of the intellect. The more we know themore we can figure; the more we can figure the more we understand; the more we understand the more we can appraise;the more we can appraise the more we can decide; the more we can decide the more we can act; the more we can act themore we can shape; and the more we can shape, the better the chance that we can leave for future generations a trulysustainable built environment which is fit-for-purpose, cost-beneficial, environmentally friendly and culturally significactCentral to this aspiration will be our understanding of the relationship between real and virtual worlds and how to moveeffortlessly between them. We need to be able to design, from within the virtual world, environments which may be real ormay remain virtual or, perhaps, be part real and part virtual.What is certain is that the next 30 years will be every bit as exciting and challenging as the first 30 years.

title	Seat preference in public squares and distribution of the surrounding people: An examination of the validity of using visual simulation
source	Motion, E-Motion and Urban Space [Proceedings of the 7th European Architectural Endoscopy Association Conference / ISBN-10: 3-00-019070-8 - ISBN-13: 978-3-00-019070-4], pp. 151-163
summary	Public squares are shared by people who use them for various purposes. When people choose seats in a square, they unconsciously evaluate not only the physical characteristics of the space but also the distribution of others already present (Hall, 1966; Sommer, 1969; Whyte, 1988). Knowing the hidden rules of this behaviour will be important in designing squares that remain comfortable even in crowded situations. Most past studies of seat choice preference have reported on statistical tendencies derived from observations of subject behavior in actually existing sites (i.e., Abe, 1997; Imai, 1999; Kawamoto, 2003). However, they provide no clear theoretical model for explaining the basic mechanisms regulating such behaviour. The present study conducts a series of experiments in both real and virtual settings in order to extract quantitative relationships between subjects’ seat preferences and the presence of nearby strangers and to clarify what factors influence their seat choices.

summary	Several research projects (Gramazio et al. 2014; Willmann et al. 2015; Helm et al. 2017; Adel et al. 2018; Adel Ahmadian 2020) have investigated the use of automated assembly technologies (e.g., industrial robotic arms) for the fabrication of nonstandard timber structures. Building on these projects, we present a novel and transferable process for the robotic fabrication of bespoke timber subassemblies made of off-the-shelf standard timber elements. A nonstandard timber structure (Figure 2), consisting of four bespoke subassemblies: three vertical supports and a Zollinger (Allen 1999) roof structure, acts as the case study for the research and validates the feasibility of the proposed process.

title	CAADRIA 2002 [Conference Proceedings]
source	Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X / Cyberjaya (Malaysia) 18–20 April 2002, 370 p.
doi	https://doi.org/10.52842/conf.caadria.2002.
summary	Evolution of trends in the realm of computer aided architectural design (CAAD) has seen the convergence of technologies – complementing traditional tools with emerging sciences like Information Technology (IT) and multimedia applications. This appliqué of technologies has not just expanded the scope and enhanced the realm of CAAD research and practice, but is also breaking new frontiers. This creative nexus will be realised at the 7th International Conference on Computer Aided Architectural Design Research In Asia (CAADRIA 2002) to be held at the Faculty of Creative Multimedia, Multimedia University, Malaysia, between 18th-20th April, 2002. CAADRIA 2002’s theme, "Redefining Content", seeks to recognise and infuse these emerging components in the field of architecture and design with a holistic approach towards online, digital and interactive systems. The 41 papers compiled were selected through a blind review process conducted by an international review panel. To reflect the multi-disciplinary nature of this year's conference, the chapters are arranged topically to facilitate the in-depth study of key components. The component sessions include: // Web Design, Database and Networks // CAD, Modelling and Tools // Collaborative Design, Creative Design and Case Reasoning // Simulation and Prototyping // Virtual Environment and Knowledge Management // Design Education, Teaching and Learning /// We believe that this specialised approach will provide a deeper and more illuminating feel of the various components and their critical convergence in the field of architecture and design.

doi	https://doi.org/10.52842/conf.caadria.2018.1.245
summary	The presented paper discusses the combination of cutting edge technology (i.e. 3D-pinting) and raw natural grown resources (i.e. bamboo) to develop resource efficient load carrying truss structures in architectural scale. Via visual sensing the individual material properties of various bamboo poles are analyzed and directly used to inform the digital model. Comparing load carrying capacity of the bamboo pole and structural requirements of the design, the poles are placed and the connections designed. Conventional 3D-pinters produce the nodes and connectors and enable to merge natural and "digital" materiality.

title	A Procedural Model for Integrating Physical and Cyberspaces in Architecture
source	Doctoral dissertation, University of Plymouth, Plymouth, U.K
summary	This dissertation articulates opportunities offered by architectural computation, in particular the digital simulation of space known as virtual reality (VR) and its networked, social variant cyberspace. Research suggests that environments that hybridize technologies call for a conception of space as information, i.e. space is both a product of and tool for cognition. The thesis proposes a model whereby architecture can employ this concept of space in creating hybrids that integrate physical and cyberspaces.The dissertation presents important developments in architectural computation that disclose concepts and values that contrast with orthodox practice. Virtual reality and cyberspace, the foci of this inquiry, are seen to embody the more problematic aspects of these developments. They also raise a question of redundancy: If a simulation is good enough, do we still need to build? This question, raised early in the 1990's, is explored through a thought experiment - the Library Paradox - which is assessed and critiqued for its idealistic premises. Still, as technology matures and simulations become more realistic the challenge posed by VR/cyberspace to architecture only becomes more pressing. If the case for virtual idealism seems only to be strengthened by technological and cultural trends, it would seem that a virtual architecture should have been well established in the decade since its introduction.Yet a history of the virtual idealist argument discloses the many difficulties faced by virtual architects. These include differences between idealist and professional practitioners, the failure of technology to achieve its proponents' claims, and confusion over the meaning of virtual architecture among both architects and clients. However, the dissertation also cites the success of virtual architecture in other fields - Human Computer Interface design, digital games, and Computer Supported Collaborative Work - and notes that their adoption of space derives from practice within each discipline. It then proposes that the matter of VR/cyberspace be addressed from within the practice of architecture, a strategy meant to balance the theoretical/academic inclination of previous efforts in this field.The dissertation pursues an assessment that reveals latent, accepted virtualities in design methodologies, instrumentation, and the notations of architectural practices. Of special importance is a spatial database that now pervades the design and construction processes. The unity of this database, effectively a project's cyberspace, and its material counterpart is the subject of the remainder of the dissertation. Such compositions of physical and cyberspaces are herein called cybrids. The dissertation examines current technologies that cybridize architecture and information technology, and proposes their integration within cybrid wholes. The concept of cybrids is articulated in seven principles that are applied in a case study for the design for the Planetary Collegium. The project is presented and critiqued on the basis of these seven principles. The dissertation concludes with a discussion of possible effects of cybrids upon architecture and contemporary culture.

title	CAD and Management of Construction Projects
source	Journal of Construction Engineering and Management, Vol. 112, December, pp. 557-565
summary	The increasing interest in computer-aided design (CAD) has prompted research that is aimed at identifying the opportunities for construction managers and building contractors. It has been found that the use of CAD systems in the U.K. is mainly confined to the production of detailed drawings. Indeed, most of the systems used are 2-D drafting tools and incapable of supporting the integration of even modest amounts of nongraphical (construction) data. On the other hand, many 3-D modeling systems have the potential to integrate construction data, although they appear to be almostignored. The use of 3-D modeling systems is considered to be the most suitable vehicle for successfully integrating these data. However, this is likely to necessitate the introduction of separate databases, preferably of the relational type. The use of 3-D modeling systems in assessing the construction implications of outline designs also presents interesting possibilities and is discussed.

summary	The article presents an experience of association between a hackerspace and a multidisciplinary design studio at the Department of Architecture and Urbanism of the Federal University of Santa Catarina, during two semesters. The Tarrafa Hacker Club members shared their collaborative environment with the students and tutors throughout the academic experiment. The hacker culture highlighted dynamic relations that connect people, information, tools and matter. This approach has suggested meaningful speculations about the future of architecture education and practice.

title	On the Facial Structure of Scheduling Polyhedra
source	49 p., 6 p. of appendix : ill. Pittsburgh, PA: Design Research Center, Carnegie Mellon Univ., December, 1984. includes bibliography
summary	A well-known job shop scheduling problem can be formulated as follows. Given a graph G with node set N and with directed and undirected arcs, find an orientation of the undirected arcs that minimizes the length of a longest path in G. The author treats the problem as a disjunctive program, without recourse to integer variables, and give a partial characterization of the scheduling polyhedron P(N), i.e., the convex hull of feasible schedules. In particular, he derives all the facets inducing inequalities for the scheduling polyhedron P(K) defined on some clique with node set K, and gives a sufficient condition for such inequalities to also induce facets of P(N). One of our results is that any inequality that induces a facet of P(H) for some HCK, also induces a facet of P(K). Another one is a recursive formula for deriving a facet inducing inequality with p positive coefficients from one with p-1 positive coefficients. The author also addresses the constraint identification problem, and gives a procedure for finding an inequality that cuts off a given solution to a subset of the constraints

doi	https://doi.org/10.52842/conf.caadria.2006.x.r4p
summary	This paper basically describes part of our current research on the role of social aspects in collaborative design. Most part of this research, up until this stage, is theoretical research, which is our attempt to imply theories in social psychology in collaborative design. In order to step further towards empirical research we needs tool for the investigation. Discussion on this paper is built upon our attempt to develop this tool. Considering this context the discussion can be observed into two sections. First part is basically summary of our theoretical research to this point. Based on these theoretical backgrounds we discuss our research on defining and developing the tool in the second part. The tool is basically a prototype of design process representation system which is expected to be used as our tool for next stages of this research, investigating the role of social aspect in the real practice of collaborative design.

title	Exploring the Unrealized Potential of Computer-Aided Drafting
source	Proceedings of CHI'96 (1996), 332-339
summary	Despite huge investments by vendors and users, CAD productivity remains disappointing. Our analysis of real- world CAD usage shows that even after many years of experience, users tend to use suboptimal strategies to perform complex CAD tasks. Additionally, some of these strategies have a marked resemblance to manual drafting techniques. Although this phenomenon has been previously reported, this paper explores explanations for its causes and persistence. We argue that the strategic knowledge to use CAD effectively is neither defined nor explicitly taught. In the absence of a well-formed strategy, users often develop a synthetic mental model of CAD containing a mixture of manual and CAD methods. As these suboptimal strategies do not necessarily prevent users from producing clean, accurate drawings, the inefficiencies tend to remain unrecognized and users have little motivation to develop better strategies. To reverse this situation we recommend that the strategic knowledge to use CAD effectively should be made explicit and provided early in training. We use our analysis to begin the process of making this strategic knowledge explicit. We conclude by discussing the ramifications of this research in training as well as in the development of future computer aids for drawing and design.

title	From Sufficient to Efficient Usage: An Analysis of Strategic Knowledge
source	Proceedings of CHI'97 (1997), 91-98
summary	Can good design guarantee the eflicient use of computer tools? Can experience guarantee it? We raise these questions to explore why empirical studies of real-world usage show even experienced users under-utilizing the capabilities of computer applications. By analyzing the use of everyday devices and computer applications, as well as reviewing empirical studies, we conclude that neither good design nor experience may be able to guarantee efficient usage. Efficient use requires task decomposition strategies that exploit capabilities offered by computer applications such as the ability to aggregute objects, and to manipulate the aggregates with powerful operators. To understand the effects that strategies can have on performance, we present results from a GOMS analysis of a CAD task. Furthermore, we identify some key aggregation strategies that appear to generalize across applications. Such strategies may provide a framework to enable users to move from a sufficient to a more ef)icient use of computer tools.

title	Delegation and Circumvention: Two Faces of Efficiency
source	Proceedings of CHI'98 (1998), 273-280
summary	Throughout history, inefficient methods to use devices have been replaced by more efficient ones. This shift typically occurs when users discover how to &legate work to the powers of a tool, and to circumvent its liiitations. Strategies of delegation and circumvention, therefore, appear to be the core of efficient use. To show how this approach can expiain the relationship between tools and strategies in complex computer systems, we describe five ways to perform a real-world drawing task with current as well as 5.rture tools. We then present five corresponding GOMS models that demonstrate the value of efficient strategies when compared to the observed behavior of a professional CAD user. We conclude by presenting a generalized framework to characterize efficient strategies and discuss its relevance to design and training.

title	The Strategic Use of Complex Computer Systems
source	Human-Computer Interaction 15 (2000), 107-137
summary	Several studies show that despite experience, many users with basic command knowledge do not progress to an efficient use of complex computer applications. These studies suggest that knowledge of tasks and knowledge of tools are insufficient to lead users to become efficient. To address this problem, we argue that users also need to learn strategies in the intermediate layers of knowledge lying between tasks and tools. These strategies are (a) efficient because they exploit specific powers of computers, (b) difficult to acquire because they are suggested by neither tasks nor tools, and (c) general in nature having wide applicability. The above characteristics are first demonstrated in the context of aggregation strategies that exploit the iterative power of computers.Acognitive analysis of a real-world task reveals that even though such aggregation strategies can have large effects on task time, errors, and on the quality of the final product, they are not often used by even experienced users. We identify other strategies beyond aggregation that can be efficient and useful across computer applications and show how they were used to develop a new approach to training with promising results.We conclude by suggesting that a systematic analysis of strategies in the intermediate layers of knowledge can lead not only to more effective ways to design training but also to more principled approaches to design systems. These advances should lead users to make more efficient use of complex computer systems.

title	CAD usage in an architectural office: from observations to active assistance
source	Automation in Construction 5 (3) (1996) pp. 243-255
summary	The functionality and resources provided by CAD systems have been increasing rapidly, but productivity growth expected from their use has been difficult to achieve. Although many surveys describe this productivity puzzle, few studies have been conducted on actual CAD users to understand its causes. In an effort to arrive at such an understanding, the first author visited a federal architectural office and observed CAD users in their natural setting. This paper describes preliminary results obtained from the study, which used ethnographic techniques developed by cultural anthropologists. The study revealed that users had leveled-off in their learning and experimentation and were using the CAD system in suboptimal ways. By asking why users were not using many resources available to them to improve performance, the observer uncovered issues of communication and management that needed to be addressed. Based on this understanding, the authors provide explicit recommendations to CAD users and vendors. In addition, they hypothesize that users might benefit from a system that provides active assistance, that is, intervenes spontaneously with advice, assistance, and relevant information while the user interacts with the CAD system. They conclude with some issues revealed by the study that should be considered when developing such active assistance.

title	Beyond Command Knowledge: Identifying and Teaching Strategic Knowledge for Using Complex Computer Applications
source	Proceedings of CHI' 01 (2001), 229-236
summary	Despite experience, many users do not make efficient use of complex computer applications. We argue that this is caused by a lack of strategic knowledge that is difficult to acquire just by knowing how to use commands. To address this problem, we present efficient and general strategies for using computer applications, and identify the components of strategic knowledge required to use them. We propose a framework for teaching strategic knowledge, and show how we implemented it in a course for freshman students. In a controlled study, we compared our approach to the traditional approach of just teaching commands. The results show that efficient and general strategies can in fact be taught to students of diverse backgrounds in a limited time without harming command knowledge. The experiment also pinpointed those strategies that can be automatically learned just from learning commands, and those that require more practice than we provided. These results are important to universities and companies that wish to foster more efficient use of complex computer applications.

title	REALMEDIA: providing multimedia-based real-estate services through the Internet
source	Automation in Construction 10 (2) (2001) pp. 275-289
summary	This paper presents the design and implementation of a software system, known as REALMEDIA, which provides Web-based, multimedia real-estate services on the Internet. REALMEDIA is innovative in that it is designed to provide both on-line services to clients and a tool for maintaining the system to real-estate agent. The software consists of a web-based interface, a client side editor and an application server. The web interface is used by both the customer and the real-estate agent to request particular services. When used by a customer, it allows the potential buyer to select and view desired properties, and to make an appointment with agents. Multimedia information, which integrates text, graphics and video clips, are presented to the customer. When used by the agent, the web interface allows the agent to dynamically update the contents of the web page and to manipulate property details through the Client Side Editor. The application server acts as a bridge between the Web Interface and the Client Side Editor. The computational architecture and major components of REALMEDIA as well as its implementation using JAVA, TCP/IP and FTP will be described.

doi	https://doi.org/10.52842/conf.caadria.2000.471
summary	A virtual environment (VE) has been designed for functioning as a three-dimensional interface to a repository of images and sounds. This paper attempts to study design interface in VEs. This study first examines the characteristics of VEs. The difference between physical and virtual environments is also studied. The relationship between both is classified as three types, i.e. complement, replacement, or independence. Then it establishes the design interface in VEs, and presents an experimental project, the virtual architecture museum (VAM). Four elements of VEs are highlighted, i.e. wayfinding, linkage, context, and atmosphere. In VAM, the interface is implemented on the web and is integrated with an architectural database. It is found that the appropriateness of design interface can enhance the users' spatial awareness, and consequently facilitate the task of navigation and wayfinding within VEs. The context and atmosphere of VEs can be defined by means of simile or metaphor through the visual or acoustic experience for gaining senses of a place.

title	Automatic Recognition of Machined Surfaces from a 3D Solid Model
source	computer Aided Design. March, 1984. vol. 16: pp. 81-86 : ill. includes bibliography
summary	It has been proposed that a direct link between CAD and CAM be provided through a computer-automated process planning system. Described in this paper are algorithmic procedures to identify machined surfaces (i.e., machining requirements) for a workpiece directly from its 3D geometric description. A machined surface is a portion of workpiece that can be generated by a certain mode of metal removal operation. Machined surfaces are algorithmically recognized from a 3D boundary file, and then their 2 1/2D descriptions are obtained in a data structure (format) suitable for an automated process planning system. A simplified boundary file data structure is introduced in order to explain the machined surface recognition procedures
keywords	A machined surface type is defined as a pattern of faces, and a syntactic pattern recognition method is used to find the machined surface from the boundary file
