summary	Building activity in Germany is moving increasingly toward combined newbuild and renovation projects. Essential for effective computer-aided planning within an existing context is not only the use of on-site computer-aided measurement tools but also an integrative cooperation between the different disciplines involved via an information and communication system. Interdisciplinary cooperation needs to be tailored to the integrative aspects in renovation and revitalisation work. Economic factors determine the viability of an architectural project, and reliable costing information is vital. Existing IT-approaches to this problem are not yet sufficiently exploited. In ongoing research at our university (collaborative research center ”Materials and Structure in the Revitalisation of Buildings”) methods and techniques of revitalisation are being investigated. A special branch of the collaborative research center is investigating possibilities of computer-aided building measurement and communication platforms for professional disciplines (www.uni-weimar.de/sfb). The aim is to develop a general approach to the revitalisation of buildings. This paper discusses possible application areas of AR/VR techniques in the revitalisation of buildings from the point of view of the user and are based on the real project “Cooling factory Gera”. Based on the necessities of revitalisation projects, technical requirements are developed. The project is funded by the Deutsche Forschungsgesellschaft (DFG).

title	Using Evolutionary Methods for Design Case Adaptation
doi	https://doi.org/10.52842/conf.acadia.2001.180
source	Reinventing the Discourse - How Digital Tools Help Bridge and Transform Research, Education and Practice in Architecture [Proceedings of the Twenty First Annual Conference of the Association for Computer-Aided Design in Architecture / ISBN 1-880250-10-1] Buffalo (New York) 11-14 October 2001, pp. 180-191
summary	Case-based reasoning (CBR) provides a methodology for directly using previous designs in the development of a new design. An aspect of CBR that is not well developed for designing is the combination and adaptation of previous designs. The difficulty with this aspect of case-based design is partly due to the extensive amounts of specialised knowledge needed to select the appropriate features of a previous design to include in the new design and the adaptation of these features to fit the context of a new design problem. In this paper we present a design process model that combines ideas from CBR and genetic algorithms (GA’s). The CBR paradigm provides a method for the overall process of case selection and adaptation. The GA paradigm provides a method for adapting design cases by combining and mutating their features until a set of new design requirements and constraints are satisfied. We have implemented the process model and illustrate the model for residential floor plan layout. We use a set of Frank Lloyd Wright prairie house layouts as the case base. The constraints used to determine whether new designs proposed by the process model are acceptable are taken from feng shui, the Chinese art of placement. This illustration not only clarifies how our process model for design through the evolutionary adaptation of cases works, but it also shows how knowledge sources with distinct origins can be used within the same design framework.

title	A Framework of Haptic Design Parameters for Architects: Sensory Paradox Between Content and Representation
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. 685-700.
summary	Architects‚Äîlike other designers‚Äîtend to think, know and work in a visual way. In design research, this way of knowing and working is highly valued as paramount to design expertise (Cross 1982, 2006). In case of architecture, however, it is not only a particular strength, but may as well be regarded as a serious weakness. The absence of non-visual features in traditional architectural spatial representations indicates how these are disregarded as important elements in conceiving space (Dischinger 2006). This bias towards vision, and the suppression of other senses‚Äîin the way architecture is conceived, taught and critiqued‚Äîresults in a disappearance of sensory qualities (Pallasmaa 2005). Nevertheless, if architects design with more attention to non visual senses, they are able to contribute to more inclusive environments. Indeed if an environment offers a range of sensory triggers, people with different sensory capacities are able to navigate and enjoy it. Rather than implementing as many sensory triggers as possible, the intention is to make buildings and spaces accessible and enjoyable for more people, in line with the objective of inclusive design (Clarkson et al. 2007), also called Design for All or Universal Design (Ostroff 2001). Within this overall objective, the aim of our study is to develop haptic design parameters that support architects during design in paying more attention to the role of haptics, i.e. the sense of touch, in the built environment by informing them about the haptic implications of their design decisions. In the context of our study, haptic design parameters are defined as variables that can be decided upon by designers throughout the design process, and the value of which determines the haptic characteristics of the resulting design. These characteristics are based on the expertise of people who are congenitally blind, as they are more attentive to non visual information, and of professional caregivers working with them. The parameters do not intend to be prescriptive, nor to impose a particular method. Instead they seek to facilitate a more inclusive design attitude by informing designers and helping them to think differently. As the insights from the empirical studies with people born blind and caregivers have been reported elsewhere (Authors 2010), this paper starts by outlining the haptic design parameters resulting from them. Following the classification of haptics into active, dynamic and passive touch, the built environment unfolds into surfaces that can act as ‚Äúmovement‚Äù, ‚Äúguiding‚Äù and/or ‚Äúrest‚Äù plane. Furthermore design techniques are suggested to check the haptic qualities during the design process. Subsequently, the paper reports on a focus group interview/workshop with professional architects to assess the usability of the haptic design parameters for design practice. The architects were then asked to try out the parameters in the context of a concrete design project. The reactions suggest that the participating architects immediately picked up the underlying idea of the parameters, and recognized their relevance in relation to the design project at stake, but that their representation confronts us with a sensory paradox: although the parameters question the impact of the visual in architectural design, they are meant to be used by designers, who are used to think, know and work in a visual way.

summary	This paper deals with the efficiency of publication means within the scientific community. Scientists spend a substantial part of their total time in visiting meetings and conferences, reading publications, writing emails, etc. Thus any improvements in the communication processes, in particular technologies which minimize non-value adding activities such as tedious retrieving of source material from library shelves, could have far-reaching (positive) consequences. In this respect a customized solution for the digitalization of paper-based conference proceedings is presented. The process of creating electronic copies of papers - disseminating knowledge on CAAD - in pdf-format is described as well as the respective decisions which were taken in this context.

summary	Activities in the building industry in Germany concentrate increasingly on a combination of renovation and new-build. A prerequisite for computer-aided planning in the context of existing buildings is both the use of on-site computer aided surveying techniques and the integration of all professional disciplines in an integrated information and communication system. Current approaches to these issues are unsatisfactory. Methods and techniques in renovation work are being investigated as part of ongoing research at the Bauhaus- Universität Weimar (SFB524 - “Collaborative research center 524 „Materials and Structure in Revitalization of Buildings”). A sub-group (SFB524 - D2 „Planning-Relevant Digital Building Surveying and Information System”) is currently investigating the possibilities of computer-aided building surveying and of joint communcation platforms for engineering disciplines (www.uni-weimar.de/sfb: May 2001). The objective is the development of a general approach for the renovation of buildings. The paper discusses concepts and requirements for a computer-aided system supporting the entire surveying process from the initial site visit to its use in a CAD system.

title	Improving design processes through structured reflection : a domain-independent approach
source	Eindhoven University of Technology
summary	In the world of designing, three fields of attention can be recognised, namely design research, design practice, and design education. Gaps exist between these three fields. In this thesis about designing, the focus is on the gap between design research and design practice. Design practice includes many design disciplines and an increasing number of multidisciplinary teams. Main problems in design practice are the communication between designers with a different background and the integration and co-ordination of important aspects during a design process. By tackling these problems, the effectiveness and efficiency of design processes in practice can be improved. The study of similarities and differences between design processes in several design disciplines and the development of support for reflection on design processes are topics that can improve design practice and that deserve more attention in design research. The goal of my research is to decrease the gap between design research and design practice in order to improve design processes. Reflection on design processes can help designers to improve their design process, its results, and the designer’s proficiency: By reflecting explicitly on the current design situation and on the performed design activities, in a systematic way and on a regular basis, designers can plan next design activities that can be performed effectively and efficiently given the design goal at that moment. In this thesis, the combination of systematic and regular reflection is called structured reflection. To improve design processes in various design disciplines in practice, the study of similarities and differences between design processes in several disciplines can be useful. Similarities between design processes are the basis for domain-independent design knowledge (as distinguished from domain-specific design knowledge). To reach the goal of my research, I have chosen to combine, in a broad explorative study, the development of support for structured reflection on design processes and the development of domain-independent design knowledge. This thesis describes a domain-independent approach to improve design processes through structured reflection. My research process can be summarised as follows. I studied three design disciplines, namely architecture, mechanical engineering, and software engineering. To get input from design practice, I did qualitative empirical research: I performed twelve case studies in the three disciplines to inventory characteristics of design processes and I compared the cases for similarities and differences. The similarities, together with the results of a literature study, have been the basis for the development of domain-independent descriptive design knowledge. The developed descriptive knowledge, in turn, formed the basis for developing domain-independent prescriptive design knowledge. At the end of the project, I confronted all results with design practice to get feedback on the results in another empirical study and I performed a literature study to position the results in the design literature. My design philosophy and design frame are the descriptive results developed to answer the first research question, namely “How to describe design processes in a domain-independent way?”. My design philosophy is a set of domain-independent concepts and terms for describing a design process. The concepts and terms are based on an application of the general theory of state-transition systems to the context of designing; the concepts of state and state transition correspond to the main concepts of design situation and design activity in my design philosophy. The answer to the first research question given by the design philosophy is refined in a design frame: The design frame offers a means to structure the description of a design process in a domain-independent way. Major structuring concepts of the design frame are dimensions and subjects. I define three dimensions, namely level, perspective, and time. These dimensions define a three-dimensional space, called a positioning space, in which important aspects of design processes can be positioned. A positioning space must be defined for each subject, being the three parts of a design situation: the product being designed, the design process, and the design context. My design frame is a domain-independent structure formed by the combination of the three dimensions for each subject. My design method is the prescriptive result developed to answer the second research question, namely “How to support structured reflection on design processes in a domain-independent way?”. My design method is a domain-independent aid that offers designers support for reflecting on design processes in a structured way. Reflection on design processes is defined as an introspective contemplation on the designer’s perception of the design situation and on the remembered design activities. A reflection process is described as a process that consists of three steps that are called preparation, image forming, and conclusion drawing. The design method is based on two main concepts: The first concept is the systematic description and analysis of design situations and design activities by means of forms and checklists; only systematic support for the preparation step of a reflection process is developed. The second concept is the idea of design sessions, introduced to stimulate designers to reflect regularly during a design process. A design session is defined as a period of time during which one or more designers are working on a subtask of a certain design task, for example, one afternoon, a whole day, or a week. Both concepts are combined to support structured reflection on design processes. The complete design method consists of five steps for each design session, namely planning a design session, defining the subtask of the design session, reflecting at the beginning of a design session, designing during the core of a design session, and reflecting at the end of a design session. A prototype software tool, called ECHO, has been developed to explore the benefits of using a software system to facilitate the use of the design method. Together, the design philosophy and the design frame offer concepts, a vocabulary, and a structure to describe design processes in a domain-independent way. The design method is a first proposal of a method that supports structured reflection on design processes. My results are thus possible answers to the mentioned research questions and are starting points to improve the effectiveness and efficiency of design processes. Based on the feedback I collected, I am optimistic about the applicability of my results in design practice. By asking input from design practice and by developing results that are useful for design practice and that contribute to design research, I contribute to decrease the gap between design research and design practice. The most important recommendations for further research are to test all results extensively in design practice and to investigate how to apply the results in design education.

title	The Impact of Internet Enabled Computer Aided Design (iCAD) in Construction Industry
doi	https://doi.org/10.52842/conf.caadria.2002.085
source	CAADRIA 2002 [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, pp. 085-92
summary	The advent of the Internet has opened up and given, particularly, the developing countries and the world in general, a transformation into collective intelligence (Levy, 1998) societies linked to digital communication (Rafi, 2001). Apart from large corporations, the rapid evolution of border-less communication has also synergise between the art and science expertise to form low-cost internet-based networks that have become multi-million dollar companies within a short period of time (e.g. Linux) (Rafi, 2001). In the context of architectural designs and construction industries, the birth of Internet-based CAD (iCAD) solutions has offered a new dimension to architectural practice. The function of CAD has expanded as a tool to communicate and collaborate as well as to better control all phases of the architectural practices. This paper will review the current available iCAD tools and explore the possible utilisation of iCAD in architectural practices. The opportunities for modifying current professional practice standards to best use iCAD will be rationalised as well as the elements in ensuring the effectiveness of iCAD implementation. The final component of the paper will be an evaluation framework to measure the value of iCAD in an architectural practice. The framework will become an early platform for an architectural practice to decide and plan their future in utilising and applying iCAD in the most efficient way.

title	The concept of Carrying in Collaborative Virtual Environments
source	Stellingwerff, Martijn and Verbeke, Johan (Eds.), ACCOLADE - Architecture, Collaboration, Design. Delft University Press (DUP Science) / ISBN 90-407-2216-1 / The Netherlands, pp. 195-208 [Book ordering info: m.c.stellingwerff@bk.tudelft.nl]
summary	Collaborative Architectural Design can take place within a virtual environment with a team of remote but virtually present people. However, in most virtual environments, the ability to perform actions is still limited to the availability of some interactive objects and a set of tools for the specific purposes of the system. As the interface of most systems is designed for unshared use, the graphic feedback signals are limited to local information about the state of objects and tools. If multiuser interaction is added to such Virtual Environments, many new possibilities and problems emerge. Users of shared applications should not only be informed about the state of local objects, tools and their own actions, they should also be made aware of what the other users undertake. Aspects, which are in daily life so obvious, should be restudied thoroughly for the application within Virtual Environments for Collaborative Design. Much research has to be undertaken in order to make such virtual places as intuitively interactive as ordinary shared working places. The 'concept of carrying', which is proposed and explained in this paper, is expected to become a useful metaphoric mechanism for solving several issues related to Spatial User Interfaces (SUI's) and Collaborative Virtual Environments (CVE's). The visual feedback from 'carrying-events' should provide more mutual understanding about ongoing processes in shared applications and it should add a more 'natural' interface for processes concerning people, tools and content in virtual and digitally augmented environments. At the start of this paper some basic human action patterns for tasks on a 2Ddesktop are compared to tasks in a 3D-environment. These action patterns are checked for their implementation in Windows Icons Menus and Pointer (WIMP) interfaces and Virtual Reality systems. Carrying is focused upon as an important interactive event in Virtual Environments. Three carrying actions related to Collaborative Architectural Design are explained by means of prototypes in Virtual Reality Modeling Language (VRML). Finally the usefulness of a general carrying concept as part of a new Visual Language is considered. The research at hand is in its first exploring phases and draws from a running PhD research about SUI's for Context Related Architectural Design and from recent experiences in CVE's.

summary	The Web is assigned an increasingly important role as a medium for information and presentation, also in architectural education. Course websites may present course materials, handouts, and manuals online. Students create their own website as a showcase of their work, complementing their portfolio. With support from a database, course websites are commonly extended to allow for electronic submission and immediate presentation of the students’ work. Such websites may be further developed to support student collaboration and communication within the context of the course. The same tools can be provided to students in order to set up their own information environments to support groupwork. We envision this technology to become commonplace in educational environments, extending the current set of electronic information and communication tools available to students. Technological advances enable practitioners and students to make the design process more information-intensive, both in their own activities and in collaboration with others. For this purpose, it is important that students familiarize themselves with such technology and adopt it in ways that meet their needs and requirements. A flexible environment that provides them with the tools and means to adapt and apply this technology throughout the curriculum, supported by course specific e-learning offerings, is our ultimate goal. In this paper, we elaborate on the efforts at the faculty of architecture in integrating current digital initiatives into an e-learning environment and on extending this environment to support the entire architecture curriculum

title	Are European cities becoming similar?
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	The paper discusses city specific development patterns to overcome todays transport problems. The results are based on recent andongoing research activities at TUW-IVV and ITS. At previous CORP-conferences, we presented the basics and the development of aplanning support tool to find optimal policy packages in urban transport and land use (Emberger, 1998), (Pfaffenbichler, Emberger, 2001). The core of this planning support tool is a dynamic land use and transport interaction model. This model, which we refer to as Sketch Planning Model (SPM), is embedded into an appraisal and optimisation framework. The SPM and this framework were developed in the recently finished European Union funded research project PROSPECTS1. Case studies with this planning supporttool were performed within PROSPECTS for the cities Edinburgh, Helsinki, Madrid, Oslo, Stockholm and Vienna. These cities are principally comparable in regards of their status (capitals and major business and education centres), but different in their size, population density, transport system etc. A set of policy instruments like public transport improvements, car traffic restrictions, and infrastructure provision was available to formulate strategies to reduce negative impacts of transport and to increase welfare. The overall objective was a sustainable development of the city. Although the instruments and the goals are similar in all investigatedcites, different solutions were adequate. The solutions vary in regard of spatial implementation, implementation time and level of implementation. The paper will highlight some reasons for the different development paths of the cities. As well the comparison of the do nothing scenario as the comparison of the most feasible policy strategies shows that European cities are different, need different solutions for their problems and will stay different in the future.

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	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
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. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title	Cunning Crafts or Poetic Place-Making? Towards a Historiography of Generative Art
source	International Conference on Generative Art
summary	This paper begins by considering the meaning and relationship between generativity and art. From there an historical analysis of these terms maps out the philosophical terrain of generative art in practice and theory. It is hypothesized that the degree to which a generativity, or birthing, may be understood as inherent in art understood as a poetic making, is the degree to which the term generative becomes a redundant qualifier of the term art. An argument is then made that art and art-making as a poetic production has an ethical vocation to critique its sources and its media in order to imagine worlds where the marginalized other, as other, is received. As a result, the unqualified adoption of computer, machine, biologicalor chemical media, as well as the mathematic or pragmatic instructions that define the execution of their works, needs to be questioned.I conclude with an historiographical examination of the Babylonian abacus and the medieval ars memoritiva, in particular, Ramon Lull’s 1274 figura universalis. Even though computing historians have claimed these as proto-computers, a deeper examination of their meaning, use and context reveal a fundamentally mimetic vocation that provides the possibility of poetic place-making, as an ethics, which is otherwise absent in thecontemporary microprocessor. The question is therefore raised whether the works presented at “generative art” galleries, websites and conferences such as this may make any claim to poetry, ethics or art per se if their use of mathematics and automation remains uncritical.

title	Interactive 3D reconstruction for urban areas. An image based tool
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 753-765
summary	Urban applications (for example arrangement, new buildings, virtual sightseeing and walkthrough) require a three dimensional (3D) geometrical model of town areas. However, most of them do not need an accurate model of reality. Such model would occupy a considerable memory space and would be too slow to handle. Architects, urban designers and civil engineers can find in our tool a medium to conceive their projects. Some types of software exist but they do not correspond exactly to our needs. Consequently we have conceived and developed an interactive tool for virtual 3D rough reconstruction of buildings. The software development has been performed in the Maya environment (ALIAS Wavefront) with C++ language and MEL (Maya Embedded Language). A constraint we set for ourselves was the use of only light devices (for easy transportation) at low price (everybody can buy such devices). The principle is to overlay on the scanned photograph of the area we want to deal with, the two dimensional (2D) cadastral plan displayed from the same viewpoint as the picture. Then each building body can be extruded from its ground polygon and the roof can be created from what the user sees on the picture. A constraint is the flatness of the polygonal surfaces. Our application context was the town of Nancy in France for which some areas have been reconstructed. Some pictures have been used as textures for polygonal surfaces, giving more reality effect to the simulation.

title	Design space navigation in generative design systems
source	Automation in Construction 11 (1) (2002) pp. 1-22
summary	Generative design systems make it easier for designers to generate and explore design alternatives, but the amount of information generated during a design session can become very large. Intelligent navigation aids are needed if designers wish to access the information they generate with ease. We present a comprehensive approach to support information navigation in requirement-driven generative design systems, which gain their power form explicit representations of design requirements, which in turn add to the information generated by the system. Our approach takes into account studies dealing with human spatial cognition, wayfinding in physical environments, and information navigation in electronic media. We structure the information to be accessed in terms of a five-dimensional design space model that applies across generative design systems of the type considered here. The model structure supports basic generic navigation operations along its five dimensions. We validated the model in the context of the SEED-Layout system and used it to extend the built-in navigation tools of the system through novel ones, which we subjected to a limited usability study. The study suggests that these tools have promise and warrant further investigation.

summary	This paper reports on recent work that focused on the potential impact of standard computer technology on the relationship between client and architect in the context of residential design. A study of software applications a client could use to develop and evaluate ideas exposed the dearth of software available for the design of spatial complexity by individuals without advanced computer skills, and led to the design of a specific piece of software we call “Space Modeler.” It was prototyped using off-the-shelf virtual reality technology, and tested by a group of freshmen students. The paper discusses the specificities of the software and provides analysis and reflection based on the results of the test, both in terms of design artifacts and users’ comments. The paper concludes that the evolution of the interface to electronic environments is a matter of interest for those concerned with rethinking the training, role and activity of the architect. In the near future prospective homeowners may be able to experience and experiment with the space of their home before it is built. How can the profession embrace new information technology developments and appropriate them for the benefits of society at large?

title	Assessment of a camera pose algorithm using images of brick sewers
source	Automation in Construction 10 (4) (2001) pp. 527-540
summary	Further developments in an ongoing multi-disciplinary research programme concerning the automation of sewer surveys are reported. Previous papers have suggested a theoretical model for use in establishing a frame of reference for closed circuit television (CCTV) camera images of non-man-entry (NME) brick sewers, in order to enable quantitative observations to be automatically acquired employing computer vision techniques. Herein is discussed a simulation testing strategy designed to determine the model's predictive accuracy and thereby assess the corresponding assumptions made. Test results are presented which display robust model characteristics. Further developments are then considered in the context of in-service practice.

title	A Quantitative Method to Compare the Impact of Design Mediums on the Architectural Ideation Process.

summary	If we compare the architectural design process to a black box system, we can assume that we now know quite well both inputs and outputs of the system. Indeed, everything about the early project either feasibility studies, programming, context integration, site analysis (urban, rural or natural), as well as the integration of participants in a collaborative process can all be considered to initiate and sustain the architectural design and ideation process. Similarly, outputs from that process are also, and to some extent, well known and identifiable. We are referring here, among others, to the project representations or even to the concrete building construction and its post-evaluation. But what about the black box itself that produces the ideation. This is the question that attempts to answer the research. Currently, very few research works linger to identify how the human brain accomplishes those tasks; how to identify the cognitive functions that are playing this role; to what extent they operate and complement each other, and among other things, whether there possibly a chain of causality between these functions. Therefore, this study proposes to define a model that reflects the activity of the black box based on the cognitive activity of the human brain. From an extensive literature review, two cognitive functions have been identified and are investigated to account for some of the complex cognitive activity that occurs during a design process, namely the mental workload and mental imagery. These two variables are measured quantitatively in the context of real design task. Essentially, the mental load is measured using a Bakan's test and the mental imagery with eyes tracking. The statistical software G-Power was used to identify the necessary subject number to obtain for significant variance and correlation result analysis. Thus, in the context of an exploratory research, to ensure effective sample of 0.25 and a statistical power of 0.80, 32 participants are needed. All these participants are students from 3rd, 4th or 5th grade in architecture. They are also very familiar with the architectural design process and the design mediums used, i.e., analog model, freehand drawing and CAD software, SketchUp. In three experimental sessions, participants were asked to design three different projects, namely, a bus shelter, a recycling station and a public toilet. These projects were selected and defined for their complexity similarity, taking into account the available time of 22 minutes, using all three mediums of design, and this in a randomly manner to avoid the order effect. To analyze the two cognitive functions (mental load and mental imagery), two instruments are used. Mental imagery is measured using eye movement tracking with monitoring and quantitative analysis of scan paths and the resulting number and duration of participant eye fixations (Johansson et al, 2005). The mental workload is measured using the performance of a modality hearing secondary task inspired by Bakan'sworks (Bakan et al.; 1963). Each of these three experimental sessions, lasting 90 minutes, was composed of two phases: 1. After calibrating the glasses for eye movement, the subject had to exercise freely for 3 minutes while wearing the glasses and headphones (Bakan task) to get use to the wearing hardware. Then, after reading the guidelines and criteria for the design project (¬± 5 minutes), he had 22 minutes to execute the design task on a drawing table allowing an upright posture. Once the task is completed, the subject had to take the NASA TLX Test, on the assessment of mental load (¬± 5 minutes) and a written post-experimental questionnaire on his impressions of the experiment (¬± 10 minutes). 2. After a break of 5-10 minutes, the participant answered a psychometric test, which is different for each session. These tests (¬± 20 minutes) are administered in the same order to each participant. Thus, in the first experimental session, the subject had to take the psychometric test from Ekstrom et al. (1978), on spatial performance (Factor-Referenced Cognitive Tests Kit). During the second session, the cognitive style is evaluated using Oltman's test (1971). Finally, in the third and final session, participant creativity is evaluated using Delis-Kaplan test (D-KEFS), Delis et al. (2001). Thus, this study will present the first results of quantitative measures to establish and validate the proposed model. Furthermore, the paper will also discuss the relevance of the proposed approach, considering that currently teaching of ideation in ours schools of architecture in North America is essentially done in a holistic manner through the architectural project.

title	Pedagogical Templates: A Comparative Study of Higher Order Reflective Making, Playful Design Learning Forum
source	Adelaide University School of Architecture, Landscape Architecture and Urban Design, Adelaide
summary	Schon's notion of reflection-in-action implies a constructivist process of learning, especially valid in the teaching of professional disciplines such as architecture. Action becomes the instrument of conjecture and learning arises in the context of reflection upon the act. Such a process of interleaving action and reflection constitutes a "higher-order" process of reflective making. Research in design studies has shown that strategies for making differ markedly between professional and novitiate designers. Further, such studies have shown that skilled designers employ past experience and precedents to create context for new problem situations. To address the lack of context in novitiate learning situations, we propose the use of "pedagogical templates" for the promotion of "higher-order" strategies in design learning contexts for supporting beginning design students. We focus on the use of digital media, specifically for the design, implementation and delivery of constructive learning situations. This paper presents the use of a pedagogical template in the creation of constructivist contexts for two complementary courses, a traditional design studio and a computermodelling course at Deakin University. The resulting implications for design learning and the integration of physical and digital forms of making through the use of a pedagogical template are discussed.
