title	CADD Curriculum - The Issue of Visual Acuity

summary	Design educators attempt to train the eyes and minds of students to see and comprehend the world around them with the intention of preparing those students to become good designers, critical thinkers and ultimately responsible architects. Over the last eight years we have been developing the digital media curriculum of our architecture program with these fundamental values. We have built digital media use and instruction on the foundation of our program which has historically been based in physical model making. Digital modeling has gradually replaced the capacity of physical models as an analytical and thinking tool, and as a communication and presentation device. The first year of our program provides a foundation and introduction to 2d and 3d design and composition, the second year explores larger buildings and history, the third year explores building systems and structure through design studies of public buildings, fourth year explores urbanism, theory and technology through topic studios and, during the fifth year students complete a capstone project. Digital media and CADD have and are being synchronized with the existing NAAB accredited regimen while also allowing for alternative career options for students. Given our location in the Los Angeles region, many students with a strong background in digital media have gone on to jobs in video game design and the movie industry. Clearly there is much a student of architecture must learn to attain a level of professional competency. A capacity to think visually is one of those skills and is arguably a skill that distinguishes members of the visual arts (including Architecture) from other disciplines. From a web search of information posted by the American Academy of Opthamology, Visual Acuity is defined as an ability to discriminate fine details when looking at something and is often measured with the Snellen Eye Chart (the 20/20 eye test). In the context of this paper visual acuity refers to a subject’s capacity to discriminate useful abstractions in a visual field for the purposes of Visual Thinking- problem solving through seeing (Arnheim, 1969, Laseau 1980, Hoffman 1998). The growing use of digital media and the expanding ability to assemble design ideas and images through point-and-click methods makes the cultivation and development of visual skills all the more important to today’s crop of young architects. The advent of digital media also brings into question the traditional, static 2d methods used to build visual skills in a design education instead of promoting active 3d methods for teaching, learning and developing visual skills. Interactive digital movies provide an excellent platform for promoting visual acuity, and correlating the innate mechanisms of visual perception with the abstractions and notational systems used in professional discourse. In the context of this paper, pedagogy for building visual acuity is being considered with regard to perception of the real world, for example the visual survey of an environment, a site or a street scene and how that visual survey works in conjunction with practice.

title	Architectural design and procedural models - A radical change of language to design in architecture
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	The history of architecture and its teaching clearly reveal how representations of the image and drawing have changed over centuries. Today, computers are increasingly found at the desks of architecture professionals and students, but their usage remains restricted to technical functions and what is commonly known as CAD (computer-assisted design), in architecture is often simply the other CAD (computer-assisted drawing).This presentation deals with architectural design, particularly at its earliest stage. Our objective is to propose a model for describing the architectural concept that meets the needs of architects through software. Only then will they really be able to use computers as an aid to design by overcoming the obstacles that presently keep us from making full use of them.This has led me to propose an avenue of exploration that examines projection through an object’s properties, and a method of computer-assisted design that makes use of procedural models. These procedural models consist of geometric operators and operators that define the properties, characteristics and performance of a building — operators which I have termed “semantic”.This research fits into a paradigm that leads to representation of the building through functions that can be called with parameters and encapsuled in an algorithm, making it possible to create procedural models that assist with the design. This approach opens up a means of integrating the logos with the figurative representation where drawing is used instead of words to convey the architectural concept.The example of a procedural model shows how we can use a generic model to produce a volume model with all the characteristics belonging to the same family of objects. This type of model can serve not only to illustrate the result of a process, or to draw connections among buildings on the basis of their construction process, or to test the validity of a rule typical of a set of objects, but also to integrate, through a functional language, semantic operators which to date have been excluded from the initial design phase. This descriptive mechanism is extremely powerful in making it possible to establish relationships among the functions and properties of a building and the purpose of the architectural project.The scientific contribution of this research is to test the hypothesis that we can use computer tools to manipulate operators which enable the architect to reappropriate a complex design of the building, and open up new lines of investigation into integrating geometric and knowledge-based systems into a unified representation. The declarative approach for creating three-dimensional scenes fits into this perspective.It is now a matter of exploring the possibility of working on a “common morphology” shared by everyone involved in the design process by rewriting the functions or by converting the functions used for representation, or else through a functional dialect (language) that allows for dialectic relationships among all types of operators and the actions of the protagonists in the architectural design process.

title	Sensitive Voxel - A reactive tangible surface
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. 525-538.
summary	Haptic and tactile sensations, the active or passive exploration of our built surroundings through our sense of touch, give us a direct feeling and detailed information of space, a sense of architecture (Pallasmaa 2005). This paper presents the prototype of a reactive surface system, which focuses its output on the sense of touch. It explains how touch sensations influence the perception of architecture and discusses potential applications that might arise from such systems in the future. A growing number of projects demonstrate the strong impact of interaction design on the human senses and perception. They offer new ways of sensing and experiencing architectural space. But the majority of these interaction concepts focus on visual and auditory output-effects. The sense of touch is typically used as an input generator, but neglected as as a potential receiver of stimuli. With all the possibilities of sensors and micro-devices available nowadays, there is no longer a technical reason for this. It is possible to explore a much wider range of sense responding projects, to broaden the horizon of sensitive interaction concepts (Bullivant 2006). What if the surfaces of our surroundings can actively change the way it feels to touch them? What if things like walls and furniture get the ability to interactively respond to our touch? What new dimensions of communication and esthetic experience will open up when we conceive of tangibility in this bi-directional way? This paper presents a prototype system aimed at exploring these very questions. The prototype consists of a grid of tangible embedded cells, each one combining three kinds of actuators to produce divergent touch stimuli. All cells can be individually controlled from an interactive computer program. By providing a layering of different combinations and impulse intensities, the grid structure enables altering patterns of actuation. Thus it can be employed to explore a sort of individual touch aesthetic, for which - in order to differentiate it from established types of aesthetic experiences - we have created the term 'Euhaptics' (from the Greek ŒµœÖ = good and Œ¨œÄœÑœâ = touch, finger). The possibility to mix a wide range of actuators leads to blending options of touch stimuli. The sense of touch has an expanded perception- spectrum, which can be exploited by this technically embedded superposition. The juxtaposed arrangement of identical multilayered cell-units offers blending and pattern effects of different touch-stimuli. It reveals an augmented form of interaction with surfaces and interactive material structures. The combination of impulses does not need to be fixed a priori; it can be adjusted during the process of use. Thus the sensation of touch can be made personally unique in its qualities. The application on architectural shapes and surfaces allows the user to feel the sensations in a holistic manner ‚Äì potentially on the entire body. Hence the various dimensions of touch phenomena on the skin can be explored through empirical investigations by the prototype construction. The prototype system presented in the paper is limited in size and resolution, but its functionality suggests various directions of further development. In architectural applications, this new form of overlay may lead to create augmented environments that let inhabitants experience multimodal touch sensations. By interactively controlling the sensual patterns, such environments could get a unique ‚Äútouch‚Äù for every person that inhabit them. But there may be further applications that go beyond the interactive configuration of comfort, possibly opening up new forms of communication for handicapped people or applications in medical and therapeutic fields (Grunwald 2001). The well-known influence of touch- sensations on human psychological processes and moreover their bodily implications suggest that there is a wide scope of beneficial utilisations yet to be investigated.

title	Normative Positions in Architectural Design - Deriving and Applying Design Methods

summary	This paper presents a recently finished course of eight weeks where CAAD skills, design methodology, and architectural theory are combined to discuss possible perspectives on the use of the computer in design, and its influence on architecture. In the course, three contemporary architects were studied; Peter Eisenman, Ben van Berkel, and Greg Lynn. Each was discussed on aspects of ontology (which are the elements of discourse), design method (design process and organization of the process), and the use of the computer (techniques and approaches). These were linked with design theory, architectural theory, and CAD-theory. The reflection on the work of the architects resulted in a number of design methods for each architect. The design methods were adapted to the available technologies in the university as well as to the scope of the exercise, since the period of eight weeks for an exercise cannot compete with design processes in practice that take many participants and much time. The students then applied the design methods to a design task: student housing and an exhibition pavilion on the campus area of the university. The task was so devised, that students could focus on either architectural or urban design level with one of the design methods. Also, the choice of architects and accompanying design methods was made in such a way that students with low, medium, and advanced computer skills could take part in the course and exercise. In a workshop held at the Czech Technical University (CVUT) in Prague, the same procedure was used in a one-week period for a different design task, but in an otherwise almost identical setting with respect to the CAAD software used. The methods and material were easily transferred to the other setting. The students were able to cope with the task and produced surprising results in the short time span available. The paper will provide an overview of the course, discuss the pedagogical implications of the work, and discuss how this particular work can be generalized to incorporate other architects and approaches.

title	On the narrative structure of Virtual Reality walkthroughs. An analysis and proposed design
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 125-138
summary	Architectural walkthroughs have often been presented as prime examples of applications that can benefit from Virtual Reality (VR) technology, but still VR presentations can be disappointing. A main reason for this is that most VR applications have been developed on purely technical criteria, with an emphasis on geometrical precision rather than experiential quality. In this paper we present a human-centered analysis and propose design solutions, by focusing on the narrative aspects of the walkthrough, such as connecting transitions of the kind used in contemporary computer games. The solutions show how such narrative enhancements can improve the user's experience of presentations at modest technical expense.

title	A digital Procedure of Building Construction: A practical project

summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title	Current work at CECA
source	International Conference on Generative Art
summary	The centre for environment computing and architecture continues to experiment with new ways to form, and this paper presents three recent projects from the MSc programme. The three projects all share underlying assumptions about the use of generative algorithms to constructform, using fractal decomposition, lindenmayer systems and the marching cubes algorithm respectively to construct three dimensional "architectural" objects. The data needed to drive the morphology however ranges from formal proportional systems and Genetic L systems programming through swarming systems to perceptive self organising neural nets. In all cases, the projects pose the question what is architectural form. While after Stanford Anderson (Anderson 66) we know it is simplistic to say that it is an automatic outcome of a proper definition of the brief, it is also difficult to accept that the form of a building is an entirely abstract geometrical object existing without recourse to social or contextual justification. In anattempt to resolve these issues we have turned to the study of systems and general system theory as a way of understanding the mechanics of emergence and morphogenesis generally, and the

title	Awareness Space in Distributed Social Networks
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 615-628
summary	In the real work environment we are constantly aware of the presence and activity of others. We know when people are away from their desks, whether they are doing concentrated work, or whether they are available for interaction. We use this peripheral awareness of others to guide our interactions and social behaviour. However, when teams of workers are spatially separated we lose 'awareness' information and this severely inhibits interaction and information flow. The Theatre of Work (TOWER) aims to develop a virtual space to help create a sense of social awareness and presence to support distributed working. Presence, status and activity of other people are made visible in the theatre of work and allow one to build peripheral awareness of the current activity patterns of those who we do not share space with in reality. TOWER is developing a construction set to augment the workplace with synchronous as well as asynchronous awareness. Current, synchronous activity patterns and statuses are played out in a 3D virtual space through the use of symbolic acting. The environment itself however is automatically constructed on the basis of the organisation's information resources and is in effect an information space. Location of the symbolic actor in the environment can therefore represent the focus of that person's current activity. The environment itself evolves to reflect historic patterns of information use and exchange, and becomes an asynchronous representation of the past history of the organisation. A module that records specific episodes from the synchronous event cycle as a Docudrama forms an asynchronous information resource to give a history of team work and decision taking. The TOWER environment is displayed using a number of screen based and ambient display devices. Current status and activity events are supplied to the system using a range of sensors both in the real environment and in the information systems. The methodology has been established as a two-stage process. The 3D spatial environment will be automatically constructed or generated from some aspect of the pre-existing organisational structure or its information resources or usage patterns. The methodology must be extended to provide means for that structure to grow and evolve in the light of patterns of actual user behaviour in the TOWER space. We have developed a generative algorithm that uses a cell aggregation process to transcribe the information space into a 3d space. In stage 2 that space was analysed using space syntax methods (Hillier & Hanson, 1984; Hillier 1996) to allow the properties of permeability and intelligibility to be measured, and then these fed back into the generative algorithm. Finally, these same measures have been used to evaluate the spatialised behaviour that users of the TOWER space show, and will used to feed this back into the evolution of the space. The stage of transcription from information structure to 3d space through a generative algorithm is critical since it is this stage that allows neighbourhood relations to be created that are not present in the original information structure. It is these relations that could be expected to help increase social density.

summary	Throughout history, profound technological shifts have been accompanied by significant cultural changes. The current shift from a technical paradigm based on physical, mechanical production to one based on electronic media impacts on forms of architectural practice in unexpected ways. The use of design software not only enhances graphic and modeling capacity but also reveals new possibilities for both form generation and fabrication. At a more subtle level it may influence the patterns of thought and creativity that have underpinned traditional forms of architectural practice. This paper examines the implications of the redefined praxis by considering the new role of ‘town and gown’ in the production of the interactive hypersurface: the AegisHypersurface©, the first working prototype of which was unveiled in March 2001.

title	Practical Navigation in Virtual Architectural Environments
source	Helsinki University of Technology, Espoo, Finland
summary	The interest towards virtual reality (VR) and virtual environments (VE) is growing all the time. The applications being developed for VE run a wide spectrum, from games to business planning. This thesis concentrates on navigation in virtual architectural environments, movement in worlds that are very similar to our own. Navigation in a virtual world should be practical, intuitive and simple. Unfortunately, it is very often far from that - for some reason the usability issues in VEs have been usually left with little attention. Currently it is easy for a user to get lost and disoriented when traveling in a VE. This situation must change, navigating through virtual environments can no longer be considered a task reserved for the experts only. 3D-worlds and architectural applications for the common user require new, intuitive interface techniques. This thesis addresses issues related to both physical and cognitive aspects of navigation as well as theoretical models that bind them together. In the technology survey of this thesis, the virtual environment technology is presented. Different visual display systems, new input devices and some 3D user interface design aspects are described. The literature survey section discusses the main issues concerning navigation theory. The two parts of navigation, travel and wayfinding, are described in detail. The major challenges are discussed and some solutions and various research results are presented. A major part of the thesis consists of the description of HCNav, a new navigation system developed by the author. The system was constructed for use in the virtual room at Helsinki University of Technology. The purpose of HCNav is to provide a very intuitive and practical navigation interface. Three new experimental input devices, namely custom wand, data glove and speech recognition system, were tested. Another important part of the work is to evaluate the effectiveness of the HCNav system. A usability test was conducted to determine if the use of HCNav was actually improving navigation performance. Twelve subjects participated in a test where HCNav was compared with a traditional navigation software used previously in the virtual room. The experiment setup has been described and the results analyzed. The results are promising and show that the navigation methods adopted in HCNav are clearly better.

summary	The various forms of two and three-dimensional applications of Computer- Aided Design provide methods for analyzing, seeing, and presenting newly realized design work. It can be used to re-create building spaces unseen since their collapse centuries ago. In our project we blur the lines between the design of new architectural spaces and the re-conception of ancient spaces, thus merging the fields of architecture and archaeology using digital technology. Archaeologists and Architects are interested in similar goals concerning the depiction of space and form but archaeologists must deduce from historical, cultural and social comparisons as well as actual excavated remains. Our project is reconstructing the 9th-century BCE Palace of Ashurnasirpal II situated in Iraq. Though much of the palace has been excavated its architecture and full artistic program will never again be fully realized. Attempting to visualize partially preserved archaeological sites depends upon deductive reasoning, empirical wisdom and sound research. By modeling digitally and using “real-time” Java-based programming, the researchers have learned more quickly about the building than through traditional flat plans, cross-sections, drawn perspectives and constructed models. We are able to “inhabit” specific interior and exterior spaces in ways not possible before. Using the tools of digital archaeology allows a myriad of educational possibilities for the scholar, student or layperson.

title	Analysis and the descriptive approach

summary	The rise of consciousness concerning the quality of working and living conditions has been a permanent though frequently underplayed theme in architecture and building since the reconstruction period. It has led to an explosive growth of programmatic requirements on building behaviour and performance, thus also stimulating the development of design analysis. The first stage of development was characterized by the evolution of prescriptive systems. These reversed the structure of pre-existing proscriptive systems into sequences of known steps that should be taken in order to achieve adequate results. Prescriptive systems complemented rather than replaced proscriptive ones, thereby creating an uncertain mixture of orthodoxy and orthopraxy that failed to provide design guidance for improving design performance and quality.The second stage in the development of design analysis focuses on descriptive methods and techniques for analyzing and supporting evaluation. Technologies such as simulation and scientific visualization are employed so as to produce detailed, accurate and reliable projections of building behaviour and performance. These projections can be correlated into a comprehensive and coherent description of a building using representations of form as information carriers. In these representations feedback and interaction assume a visual character that fits both design attitudes and lay perception of the built environment, but on the basis of a quantitative background that justifies, verifies and refines design actions. Descriptive analysis is currently the most promising direction for confronting and resolving design complexity. It provides the designer with useful insights into the causes and effects of various design problems but frequently comes short of providing clear design guidance for two main reasons: (1) it adds substantial amounts of information to the already unmanageable loads the designer must handle, and (2) it may provide incoherent cues for the further development of a design. Consequently the descriptive approach to analysis is always in danger of been supplanted by abstract decision making.One way of providing the desired design guidance is to complement the connection of descriptive analyses to representations of form (and from there to synthesis) with two interface components. The first is a memory component, implemented as case-bases of precedent designs. These designs encapsulate integrated design information that can be matched to the design in hand in terms of form, function and performance. Comparison between precedents with a known performance and a new design facilitate identification of design aspects that need be improved, as well as of wider formal and functional consequences. The second component is an adaptive generative system capable of guiding exploration of these aspects, both in the precedents and the new design. The aim of this system is to provide feedback from analysis to synthesis. By exploring the scope of the analysis and the applicability of the conclusions to more designs, the designer generates a coherent and consistent collection of partial solutions that explore a relevant solution space. Development of the first component, the design case-bases, is no trivial task. Transformability in the representation of cases and flexible classification in a database are critical to the identification and treatment of a design aspect. Nevertheless, the state of the art in case-based reasoning and the extensive corpus of analysed designs provide the essential building blocks. The second component, the adaptive generative system, poses more questions. Existing generative techniques do not possess the necessary richness or multidimensionality. Moreover, it is imperative that the designer plays a more active role in the control of the process than merely tweaking local variables. At the same time, the system should prevent that redesigning degenerates into a blind trial-and-error enumeration of possibilities. Guided empirical design research arguably provides the means for the evolutionary development of the second component.

title	Spatial Orientation in Virtual Environments
source	Delft University of Technology
summary	Recently, a growing interest can be detected in the application of Virtual Environment (VE) technology as an operator interface. VEs are three-dimensional computer-generated images that can be shown on a conventional monitor, on a large screen display, or on a head-mounted display. In order to use these three-dimensional interfaces for finding and retrieving information, the user must be able to spatially orient themselves.Different types of VE technology are available for navigating in these VEs, and different types of navigation can be enabled. A choice has to be made between the different options to enable good spatial orientation of the user. There are two main types of VE interfaces: an immersive interface that provides rich sensory feedback to the user when moving around in the VE, and a non-immersive interface that provides only visual feedback to the user when moving around in the VE. Furthermore, navigation through the VE can either be continuous providing fluent motion, or can be discontinuous which means that the viewpoint is displaced instantaneously over a large distance.To provide insight into the possible effects of these options a series of nine experiments was carried out. In the experiments the quality of spatial orientation behaviour of test subjects is measured while using the different types of interface and the different types of navigation.The results of the experiments indicate that immersive navigation improves the perception of displacement through the VE, which in turn aids the acquisition of spatial knowledge. However, as soon as the spatial layout of the VE is learned the two types of navigation interface do not lead to differences in spatial orientation performance. A discontinuous displacement leads to temporary disorientation, which will hinder the acquisition of spatial knowledge. The type of discontinuous displacements has an effect on the time needed for anticipation. The disorienting effects of a discontinuous displacement can be compensated for by enabling cognitive anticipation to the destination of the displacement.These results suggest that immersive navigation might only be beneficial for application domains in which new spatial layouts have to be learned every time or in domains where the primary users are novices. For instance, in training firemen to teach them the layout of new buildings with VE, or in using architectural walkthroughs in VE to show new building designs to potential buyers. Discontinuous movement should not be allowed when exploring a new environment. Once the environment is learned and if fast displacement is essential then discontinuous displacement should be preferred. In this case, the interface designer must make sure that information is provided about the destination of a discontinuous displacement.

summary	An addition to a building was designed using virtual reality (VR). The project was part of a design studio for graduate students of architecture. During the design process a detailed journal of activities was kept. In addition, the design implemented with VR was compared to designs implemented with more traditional methods. Both immersive and non-immersive VR simulations were attempted. Part of the rationale for exploring the use of VR in this manner was to develop insight into how VR techniques can be incorporated into the architectural design process, and to provide guidance for the implementers of future VR systems. This paper describes the role of VR in schematic design, through design development to presentation and evaluation. In addition, there are some comments on the effects of VR on detailed design. VR proved to be advantageous in several phases of the design. However, several shortcomings in both hardware and software became apparent. These are described, and a number of recommendations are provided.

title	DesignBUF: Exploring and Extending 2D Boolean Set Operations with Multiple Modes in the Early Design Phase
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 589-602
summary	Boolean set operations have been a powerful design function set for any CAD systems including 2D and 3D domains. Their capacity to provide even more powerful design tools have not, however, been fully explored in the 2D system. The purpose of this study is to further explore 2D Boolean set operations with multiple modes, which include a pick mode, a wait mode, a drag-and-drop mode, and a draw-and-action mode. We develop a prototype design tool, called DesignBUF. It introduces a new concept of “design object buffer,” an intermediate design zone in which a designer freely sketches his/her design with design objects in a brainstorming fashion since valuable design ideas are ephemeral? and the designer needs to generate design schemes rapidly before the ideas disappear or are forgotten. After finishing such fast brainstorming processes, especially in the early design phase, the designer gets a stable and refined form of a floor plan, which in turn becomes a well structured form to maintain building and design information systematically. Therefore, the designer keeps switching back and forth between the “design object buffer” and structured floor plans. We believe that this dual working memory will not only increase system flexibility, but also reduce computation with unnecessarily complex design objects. This study also develops a robust algorithm to transform the intermediate design objects into a well-structured floor plan. In fact, the algorithm is also used for the extended Boolean set operations described above. A structured floor plan can also be transformed into non-structured forms. Research issues for future development are also identified at the end of the paper.

title	Highlighting the affordances of designs. Mutual realities and vicarious environments
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 681-696
summary	Computer-aided evaluation of predicted design performance is an enduring theme within CAAD research and practice. However, most evaluative systems address aspects of design that are readily amenable to formal or quantitative treatments. Analyses of how people use and interact with designs rarely progress beyond a narrow functionalism, in which ‘the user’ figures as a type with poorly defined needs and characteristics. This paper outlines a theory of actor-environment interaction based on Gibson’s notion of affordance as a precursor to exploring how computers can be used to highlight the affordances of designs. Two simple prototypes are described. The main conclusion is that while computers are unlikely to be able to detect affordances, they can generate and present information in ways that will enable human designers to appreciate more fully the possible implications of their designs for a broader range of potential occupants.

title	Structural Composite Members in Architecture Fabricated by CAD/CAE/CAM Technology
source	Harvard University
summary	The doctoral research in this dissertation is aimed at exploring new materials and innovative methods for fabricating complex-shaped buildings, which have surfaced as a prevailing trend in architecture today. Over the past few years, the field of architecture has witnessed revolutionary changes in design. The recent completion of Frank O. Gehry's new Guggenheim Museum in Bilbao, Spain, brought unprecedented attention to complex-shaped, non-conventional designs and its influence on the global architectural trend has been immense. In following these latest trends, the author was drawn to the issues concerning construction materials and methods that are being currently adopted in realizing these complicated designs. It is perhaps inevitable that the traditional steel construction methods, suitable for use in the conventional linear shapes, face tremendous challenges and limitations in building such complex-shaped designs. In the author's opinion, the next step to go from here is to seek joint efforts between the architectural field and the engineering field to search for a new methodology which will best serve the contemporary design style. This research first focused on examining the problems that traditional methods pose for the new complex-shaped buildings. Paying attention to Gehry's recent projects, the author was able to identify major difficulties in association with representing and constructing these complicated shapes, mainly in terms of the relationship between the primary structure and the envelope surface. The second part of the research moved on to proposing a new alternative to the traditional methods, by utilizing polymer composite materials (PCM) as construction material and employing advanced Computer-Aided Design (CAD)/Computer Aided Engineering (CAE)/Computer-Aided Manufacturing (CAM) technologies. More specifically, the author has attempted to present effective theories in support of the two following ideas: (1) circular tubes made of PCM are the most promising alternative to regular steel members, especially steel tubes, to follow the envelope surface of the complex shaped building. (2) state-of-the-art CAD/CAE/CAM technologies are the most essential tools to achieve the geometrical and functional quality of the proposed new material. In the second phase, the primary focus of the quantitative approach was on fabricating an experimental model (1:1 scale prototype) called “ a unit of boundary structures”, the basic unit of structure system that wraps a complex-shaped building's entire territory .

title	Reflections on e-Design: The e-Studio Experience
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	The influence of digital media and information technology on architectural design education and practice is increasingly evident. The practice and learning of architecture is increasingly aided by and dependant on digital media. Digital technologies not only provide new production methods, but also expand our abilities to create, explore, manipulate and compose space. In contemporary design education, there is a continuous demand to deliver new skills in digital media and to rethink architectural design education in the light of the new developments in digital technology. During the academic years 2001-2003, I had the chance to lead the efforts to promote an effective use of digital media for design education at Department of Architecture, Jordan University of Science and Technology (JUST). Architectural curriculum at JUST dedicated much time for teaching computing skills. However, in this curriculum, digital media was taught in the form of "software use" education. In this context, digital media is perceived and used mainly as a presentation tool. Furthermore, Computer Aided Architectural Design and architectural design are taught in separate courses without interactions between the two.

title	Games One : Two : Three A triangle of virtual game scenarios for architectural collaboration
source	Stellingwerff, Martijn and Verbeke, Johan (Eds.), ACCOLADE - Architecture, Collaboration, Design. Delft University Press (DUP Science) / ISBN 90-407-2216-1 / The Netherlands, pp. 95-120 [Book ordering info: m.c.stellingwerff@bk.tudelft.nl]
summary	This paper is split into three parts, each of which deals with different aspects of, and approaches to, the collaboration process. Each of the approaches shares a common root in an aspect of games or gaming. Together the three approaches represent a tripartite attack on the spectrum of problems that need to be addressed to achieve successful collaboration. The first technique is dealt with in Game One One. This deals with the issue of encouraging collaboration. It is based on work using a role playing game scenario and is intended to allow construction industry professionals and clients to develop a common framework for discussion. It originally existed as a paper based game and is now being tested in a web-based environment. Game Two is based on work that has evolved from contemporary game and meeting place environments that have been attracting attention recently. Here internet-based three-dimensional worlds are used as a virtual replacement of real spaces and participants meet as avatars. In the architectural context we have investigated the potential for application of such 3D worlds as meeting, and discussion places where architectural information and ideas can be exchanged. In Game Three we take the idea that currently, virtual environments are still rather uncomfortable and unnatural in terms of human interaction, and in particular in the way that we move around and display architectural scenes. We develop the idea that games software incorporates techniques that make the representation of animated, interactive 3D architectural environments computationally efficient. We have augmented the software used in games environments and have considered how we construct architectural models and man-machine interfaces to improve the effectiveness of such environments in an architectural context.

title	Architectural critique through digital scenariobuilding. Augmenting Architectural Criticism and Narrative
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 697-709
summary	As an idea scenario-building has parallels the use of creative faking in related disciplines, most particularly, in contemporary art. The techniques involved in scenario-building and faking offer us enhanced ways of undertaking creative thinking and critical review of architecture and architectural projects. Critical review and theoretical analysis of architecture can be undertaken via a range of methods that Attoe (1978) classifies as Normative, Interpretive and Descriptive. Digital representation now offers us new ways of augmenting these critical styles in ways that have yet to be fully exploited, and possible means of exploitation are illustrated in this paper. In short the work described here shows how digital techniques can be used to enrich architectural investigation, critical reporting and debate.
