title	Analysis of the use of computer media by expert and novice designers
doi	https://doi.org/10.52842/conf.caadria.2001.071
source	CAADRIA 2001 [Proceedings of the Sixth Conference on Computer Aided Architectural Design Research in Asia / ISBN 1-86487-096-6] Sydney 19-21 April 2001, pp. 71-80
summary	This paper is based on an experiment of protocol analysis. In order to investigate the differences in models designed under various circumstances, the paper attempts to find out how expert and novice designers develop their designs with computer media. It also compares expert designers with their novice counterparts by analyzing and generalizing some cases in their thinking and designing process. Thus a designer who is very familiar with software and have expertise in design must apply different strategies to their design. This is indeed the cause of changes in the process of promoting from a novice to an expert designer. Therefore, the differences between novices and experts can be one of the foci of educating novice designers.

title	A Digital Design Coach for Young Designers
doi	https://doi.org/10.52842/conf.acadia.2001.330
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. 330-335
summary	The present use of digital media in architectural practice and education is primarily focused on representation, communication of ideas and production. Designers, however, still use pencil and paper to assist the early conception of ideas. Recently, research into providing digital tools for designers to use in conceptual designing has focused on enhancing or assisting the designer. Rarely has the computer been regarded as a potential teaching tool for design skills. Based on previous work by the author about visual thinking and the justification for a digital design assistant, the intention of this paper is to illustrate to the reader the feasibility of a digital design coach. Reference is made to recent advances in research about design computability. In particular, research by Mark Gross and Ellen Do with respect to their Electronic Cocktail Napkin project is used as a basis on which to determine what such a digital coach may look and feel like.

title	Designers‚ Cognition in Traditional versus Digital Media during Conceptual Design
source	Bilkent University Ankara Turkey
summary	Designers depend on representations to externalize their design thoughts. External representations are usually in the form of sketches (referred to as traditional media) in architectural design during the conceptual design. There are also attempts to integrate the use of digital representations into the conceptual design in order to construct a digital design medium. This thesis aims at gaining an insight on designers’ cognitive processes while sketching in digital versus traditional media. The analysis of cognitive processes of designers based on their protocols is necessary to reveal their design behavior in both media. An experiment was designed employing six interior architects (at Bilkent University) solving an interior space planning problem by changing the design media they work with. In order to encode the design behavior, a coding scheme was utilized so that inspecting both the design activity and the responses to media transition was possible in terms of primitive cognitive actions of designers. The analyses of the coding scheme constituents, which are namely segmentation and cognitive action categories enabled a comparative study demonstrating the effect of the use of different media in conceptual design phase. The results depicted that traditional media had advantages over the digital media such as supporting perception of visual-spatial features, and organizational relations of the design, production of alternative solutions and better conception of the design problem. These results also emerged implications for the computer aid in architectural design to support the conceptual phase of the design process.

title	Digital Architecture in CAD studio and Internet-based competition
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	Architectural design has been changing because of the vast and creative use of computer in different ways. From the viewpoint of designing itself, computer has been used as drawing tools in the latter phase of design (Mitchell 1977; Coyne et al. 1990), presentation and simulation tools in the middle phase (Liu and Bai 2000), and even critical media which triggers creative thinking in the very early phase (Maher et al. 2000; Liu 1999; Won 1999). All the various roles that computer can play have been adopted in a number of professional design corporations and so-called computer-aided design (CAD) studio in schools worldwide (Kvan 1997, 2000; Cheng 1998). The processes and outcomes of design have been continuously developing to capture the movement of the computer age. However, from the viewpoint of social-cultural theories of architecture, the evolvement of design cannot be achieved solely by designers or design processes. Any new idea of design can be accepted socially, culturally and historically only under one condition: The design outcomes could be reviewed and appreciated by critics in the field at the time of its production (Csikszentmihalyi 1986, 1988; Schon and Wiggins 1992; Liu 2000). In other words, aspects of design production (by designers in different design processes) are as critical as those of design appreciation (by critics in different review processes) in the observation of the future trends of architecture.Nevertheless, in the field of architectural design with computer and Internet, that is, so-called computer-aided design computer-mediated design, or internet-based design, most existing studies pay more attentions to producing design in design processes as mentioned above. Relatively few studies focus on how critics act and how they interact with designers in the review processes. Therefore, this study intends to investigate some evolving phenomena of the interaction between design production and appreciation in the environment of computer and Internet.This paper takes a CAD studio and an Internet-based competition as examples. The CAD studio includes 7 master's students and 2 critics, all from the same countries. The Internet-based competition, held in year 2000, includes 206 designers from 43 counties and 26 critics from 11 countries. 3 students and the 2 critics in the CAD studio are the competition participating designers and critics respectively. The methodological steps are as follows: 1. A qualitative analysis: observation and interview of the 3 participants and 2 reviewers who join both the CAD studio and the competition. The 4 analytical criteria are the kinds of presenting media, the kinds of supportive media (such as verbal and gesture/facial data), stages of the review processes, and interaction between the designer and critics. The behavioral data are acquired by recording the design presentation and dialogue within 3 months. 2. A quantitative analysis: statistical analysis of the detailed reviewing data in the CAD studio and the competition. The four 4 analytical factors are the reviewing time, the number of reviewing of the same project, the comparison between different projects, and grades/comments. 3. Both the qualitative and quantitative data are cross analyzed and discussed, based on the theories of design thinking, design production/appreciation, and the appreciative system (Goodman 1978, 1984).The result of this study indicates that the interaction between design production and appreciation during the review processes could differ significantly. The review processes could be either linear or cyclic due to the influences from the kinds of media, the environmental discrepancies between studio and Internet, as well as cognitive thinking/memory capacity. The design production and appreciation seem to be more linear in CAD studio whereas more cyclic in the Internet environment. This distinction coincides with the complementary observations of designing as a linear process (Jones 1970; Simon 1981) or a cyclic movement (Schon and Wiggins 1992). Some phenomena during the two processes are also illustrated in detail in this paper.This study is merely a starting point of the research in design production and appreciation in the computer and network age. The future direction of investigation is to establish a theoretical model for the interaction between design production and appreciation based on current findings. The model is expected to conduct using revised protocol analysis and interviews. The other future research is to explore how design computing creativity emerge from the process of producing and appreciating.

title	A digital design coach for young designers
doi	https://doi.org/10.52842/conf.caadria.2001.311
source	CAADRIA 2001 [Proceedings of the Sixth Conference on Computer Aided Architectural Design Research in Asia / ISBN 1-86487-096-6] Sydney 19-21 April 2001, pp. 311-314
summary	It is the intention of this paper is to construct for the reader a suitable foundation on which to determine a digital design coach. It seeks to define this possibility by examining two ideas. The first is visual thinking, as used by designers in the process of design. The second idea, that of providing students with expert partners for the learning of design is supported by evidence from a variation on protocol analysis (developed by the author) and a related design studio conducted in New Zealand and Jamaica. Using these concepts in relation to recent advances in the development of digital tools the paper proposes what a digital coach may look like.

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	Evaluating Office Buildings with MOLCA(Model for Office Life Cycle Assessment)
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	MOLCA (Model for Office Life Cycle Assessment) is a project that aims to develop a tool that enables designers and builders to evaluate the environmental impact of their designs (of office buildings) from a environmental point of view. The model used is based on guidelinesgiven by ISO 14000, using the so-called Life Cycle Assessment (LCA) method. The MOLCA project started in 1997 and will be finished in 2001 resulting in the aforementioned tool. MOLCA is a module within broader research conducted at the Eindhoven University of Technology aiming to reduce design risks to a minimum in the early design stages.Since the MOLCA project started two major case-studies have been carried out. One into the difference in environmental load caused by using concrete and steel roof systems respectively and the role of recycling. The second study focused on biases in LCA data and how to handle them. For the simulations a computer-model named SimaPro was used, using the world-wide accepted method developed by CML (Centre for the Environment, Leiden, the Netherlands). With this model different life-cycle scenarios were studied and evaluated. Based on those two case studies and a third one into an office area, a first model has been developed.Bottle-neck in this field of study is estimating average recycling and re-use percentages of the total flow of material waste in the building sector and collecting reliable process data. Another problem within LCA studies is estimating the reliability of the input data and modelling uncertainties. All these topics will be subject of further analysis.

title	The Hsinchu experience: a computerized procedure for visual impact analysis and assessment
source	Automation in Construction 10 (3) (2001) pp. 337-343
summary	This paper examines the procedure of visual impact analysis and assessment (VIAA) proposed by Rahman and reviews the use of computer-aided design (CAD) applications in urban projects in the real world. A preliminary computerized procedure for VIAA is proposed. An experiment was conducted in our laboratory to verify the preliminary procedure. In order to further study the revised procedure in real urban projects, it was also applied into the renew project of The Eastern Gate Plaza located in the center of Hsinchu, Taiwan from 1996 to 1998. Based on the face-to-face discussions with Hsinchu habitants, government officials, and professional designers, a final computerized procedure for VIAA is concluded.

title	Ivy: Bringing a Weighted-Mesh Representations to Bear on Generative Architectural Design Applications
doi	https://doi.org/10.52842/conf.acadia.2016.140
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 140-151
summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

title	Toward a procedure of computer simulation in the restoration of historical 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	In the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

title	Visual Cues in the CYBER-REAL Complex
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	Current Computer Aided Architectural Design deals with issues of complexity in creation and interpretation of the built environment, complexity of the computer systems and complexity of the representations of the design object. The term ‘CYBER-REAL Complex’ in this paper is defined as the whole (un)conscious state of the architectural design project in the heads of the design-group and as how it is maintained in CAAD systems. The ‘CYBER-REAL Complex’ contains the design, its context and all related information such as planning, product specifications and design ideas. An Intranet is an interesting means for storage and approach of such complex project-data. However the knowledge and data of the project participants remains in their heads and new methods have to be developed in order to get each participant to share his or her personal information about the project. Meetings and intense data retrieval by an Intranet can establish a useful ‘CYBER-REAL Complex’. Then, as a designer wants to approach and change the information in the ‘CYBER-REAL Complex’, a very good set of tools, methods and media has to be at hand. The complexity of all the information can be overwhelming and it can take much effort to re-understand and re-interpret the information before new decisions and design-steps can be made. Currently, the understanding of CAAD representations by the designer and the deliberate execution of operations on increasingly complex datasets through increasingly complex user interfaces takes too much time and effort. An enhanced way of representation in the ‘CYBER-REAL Complex’ could help the approach and understanding of the information. Therefore the visual language of information systems needs further research and development. This paper explores several limits of human perception and ways to adhere to the human way of visual thinking in order to find and add new visual cues in CAAD, VR interfaces and in the ‘CYBER-REAL Complex’ as a whole. Successively the perceptive aspects of complex information, the role of visual cues in complex information and several examples of visual cues in research tests are presented. The paper draws from knowledge of the Gestalt Theory, Perception Research and findings of a PhD research project about Visual Language for Context Related Architectural Design. Findings of this research show that designers use distinct views to get overview and insight in the project data and that different kinds of data representation are needed for different phases in the design process. Finally it showed that abstract represented and filtered information can be very useful for remaining focus in the otherwise overwhelming dataset.

title	The comparison of animation, virtual reality, and scenario scripting in design process
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	Design media is a fundamental tool, which can incubate concrete ideas from ambiguous concepts. Evolved from freehand sketches, physical models to computerized drafting, modeling (Dave, 2000), animations (Woo, et al., 1999), and virtual reality (Chiu, 1999; Klercker, 1999; Emdanat, 1999), different media are used to communicate to designers or users with different conceptual levels¡@during the design process. Extensively employed in design process, physical models help designers in managing forms and spaces more precisely and more freely (Millon, 1994; Liu, 1996).Computerized drafting, models, animations, and VR have gradually replaced conventional media, freehand sketches and physical models. Diversely used in the design process, computerized media allow designers to handle more divergent levels of space than conventional media do. The rapid emergence of computers in design process has ushered in efforts to the visual impact of this media, particularly (Rahman, 1992). He also emphasized the use of computerized media: modeling and animations. Moreover, based on Rahman's study, Bai and Liu (1998) applied a new design media¡Xvirtual reality, to the design process. In doing so, they proposed an evaluation process to examine the visual impact of this new media in the design process. That same investigation pointed towards the facilitative role of the computerized media in enhancing topical comprehension, concept realization, and development of ideas.Computer technology fosters the growth of emerging media. A new computerized media, scenario scripting (Sasada, 2000; Jozen, 2000), markedly enhances computer animations and, in doing so, positively impacts design processes. For the three latest media, i.e., computerized animation, virtual reality, and scenario scripting, the following question arises: What role does visual impact play in different design phases of these media. Moreover, what is the origin of such an impact? Furthermore, what are the similarities and variances of computing techniques, principles of interaction, and practical applications among these computerized media?This study investigates the similarities and variances among computing techniques, interacting principles, and their applications in the above three media. Different computerized media in the design process are also adopted to explore related phenomenon by using these three media in two projects. First, a renewal planning project of the old district of Hsinchu City is inspected, in which animations and scenario scripting are used. Second, the renewal project is compared with a progressive design project for the Hsinchu Digital Museum, as designed by Peter Eisenman. Finally, similarity and variance among these computerized media are discussed.This study also examines the visual impact of these three computerized media in the design process. In computerized animation, although other designers can realize the spatial concept in design, users cannot fully comprehend the concept. On the other hand, other media such as virtual reality and scenario scripting enable users to more directly comprehend what the designer's presentation.Future studies should more closely examine how these three media impact the design process. This study not only provides further insight into the fundamental characteristics of the three computerized media discussed herein, but also enables designers to adopt different media in the design stages. Both designers and users can more fully understand design-related concepts.

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	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	Physically Based Daylight Simulation and Visualization

summary	While architects typically agree that daylight is a powerful influence for design, architects rarely collect and use daylighting data to help make informed design decisions. This deficiency exists partially because there are no common tools available to provide useful and accessible data. The objective of this project is to provide accurate daylighting data of a prominent urban building site and present it in a clear way so that the architects can make well informed design decisions that respond to site daylighting conditions and improve architectural performance. An urban 3D computer model was created with AutoCad, a commercial CAD application. Daylight was simulated with Radiance, the physically based rendering engine developed at Lawrence Berkeley National Laboratory. The standard CIE model for clear sky and sun was used to produce over 500 images that represent daylight conditions for three different times of year at 10 minute intervals in both luminance and illuminance formats. The simulation data was packaged for analysis with a unique browser tool that enables the architect to easily cycle through the data to evaluate and compare behavior by time of day and by season. The architect can also toggle between luminance and illuminance format to easily visualize both qualitative and quantitative data. The exploration and use of the simulation data can be applied with sensitivity to inform the design and decision making process for the exterior building site.

title	Information Rich 3D Computer Modeling of Urban Environments
source	Working Paper 35, Centre for Advanced Spatial Analysis Working Papers; London, August 2001
summary	We are living in an increasingly information rich society. Geographical Information Systems now allow us to precisely tag information to specific features, objects and locations. The Internet is enabling much of this information to be accessed by a whole spectrum of users. At CASA we are attempting to push this technology towards a three-dimensional GIS, that works across the Internet and can represent significant chunks of a large city. We believe that the range of possible uses for such technology is diverse, although we feel that urban planning is an area that can benefit greatly. An opportunity to push this ìplanning technologyî arose when CASA won a tender from Hackney Council to develop a dynamic website for community participation in the process of regenerating the Woodberry Down Estate. This is a run down part of northeast London that is undergoing a major redevelopment. CASA has developed a system that not only informs the local residents about the redevelopment process but it also enables them to use dynamic visualisations of the ìbefore and after effectsî of different plans, and then to discuss and vote on the variety of options.

title	Is a Figure-Concept Binary Argumentation Pattern Inherent in Visual Design Reasoning?
source	J. S. Gero, B. Tversky and T. Purcell (eds), 2001, Visual and Spatial Reasoning in Design, II - Key Centre of Design Computing and Cognition, University of Sydney, Australia
summary	This paper is based on the assumption that because designingis aimed at specifying configurations of entities, designers mustmanipulate forms and shapes and they must resort to visual reasoning todo so. Visual reasoning in designing is seen as the interplay betweenfigural and conceptual reasoning, such that the one supports andcontinues the other in order to arrive at a configuration that is valid interms of all the requirements it is to satisfy. We use protocol analysis toexplore the bond between conceptual and figural reasoning at two levelsof cognitive operation – that of the design move and that of theargument that is its building block. We conclude that the two modes ofreasoning are equi-present in designing; they describe a binary systemcharacterized by high frequency shifts between figure and concept.
