title	An Insight into the Freedom of Using a Pen: Pen-based System and Pen-and-paper
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 385-393

summary	In earlier researches on freehand sketching, the cognitive behavior of designers was studied. In recent years, some researchers began to look into this area from the design media aspect. The pen-based system, developed by Gross, Landay and other researchers, used the pen as an input device, allowing sketches to be freely drawn in a computer environment. The importance of the freehand sketch lies in its ability to freely represent various drawing projections using ambiguous sketches. However, as for the various drawing projections, such as diagrams, symbols, plans, elevations, sections, perspectives, etc., how are they interrelated to a designer’s thinking process and the cognitive behavior? Different media have different abilities to represent different projections. Would they affect the designer’s design thinking as well? Targeting different media, i.e., conventional freehand sketches vs. the computer pen-based system, this research uses case studies and think-aloud protocol analysis to present an analysis and discussion. Research results show that there is a relationship of gradual embodiment that is mutually complementary, going from a whole perspective to being the dissected into sections between the different projections. In addition, these projections restrict the designer’s various design thinking processes, while the use of different media may somewhat change the actual design thinking of the designer

title	Four Degrees Of Freedom
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, p. 17

summary	Letting go is hard to do. Remember back to when, after months of trying, you let go of the handlebars of your bicycle and sailed down the street, effortless and assured. It was a freedom born of mastery, balance and technique. You had let go, but were in control. Technique extends to other devices as well and we are here to discuss architectural computation. Here too, as we will see, mastery is shown by letting go. These papers explore new degrees of freedom in design computation. Each is on a separate aspect of architecture, whether it be aesthetics, process, or structure. Two papers inquire into the entities of design and the processes by which they are manifested. They pose important questions. If we can affect the course of design going forward, are we free to change its past? By defining the characteristics of objects at the outset, are we through automation free to choose from a refined spectrum of outcomes? From the evidence of these papers, the answer to both questions is yes. Through the agency of parametric design we can affect the future and past of architectural processes and their products. Rather than being locked into rigid, linear decisions we are temporally free to choose, tweak and modify. Choice and chance play an important role in aesthetics as well. This has become emblematic of design trends as we have seen in recent years. One of our papers addresses the indeterminacy of particle systems in the design of a monument to the victims of 9/11. By letting go of the handlebars of the computer, the author has been freed to new, poetic forms and processes. Another paper opens urban design to its client community by use of a sophisticated web site. In the tradition of populist innovators like Charles Moore and Lucien Kroll, the authors have extended the design process beyond the office walls to the city itself. The designers, by loosening their grip on the project have made the effort democratic and participatory. Intriguingly, at the end of the paper, they note that this use of cyberspace opens the door to a non-physical architecture. Could architecture, then, let go its materialist biases as well? We hope to engage this and other questions shortly.We are pleased then, to share with you these insights and projects. Wassim and I hope that these presentations will be as liberating for you as they were for us.

title	A Critical Evaluation of Early Stages Software in its Capacity of Coping with Contextual Issues
source	LOCAL VALUES in a NETWORKED DESIGN WORLD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Stellingwerff, Martijn and Verbeke, Johan (Eds.), (2004) DUP Science - Delft University Press, ISBN 90-407-2507-1.
summary	In this paper we analyse critically early design stages software in its capacity of coping with contextual data at large (i.e. representing cultural, aesthetical context, etc.). We identified 5 categories of early stages software: geometry based graphic editors, evaluation architectural software, generative and shape-grammar based systems, evolutionary systems and other systems. Calling the object under creation during of the early stages a CAD conceptual model, we will investigate to what extend this software allows the architect to experience and represent the context in which a design is situated. Especially we will focus on its capacity to allow interaction, playful interaction on our way to the design. Designers, and particularly architects, interact with the local context similarly to interacting in a game: the context influences the users’ decisions, surprises them and causes permanent changes to their ways of thinking. On the other hand, architects permanently shape and reshape the context, and reduce the context to a protean point of reference. Such behaviour characterises creative thinking that is crucial for the early stage of design. The investigation led us to the conclusions that the effective interactivity with the context needs simple rules, a plain interface and data reduced as simple as possible, especially when interaction with the context is performed during the early stages of a design process. The findings can be used in organising computer environments for early-stage design.

title	Making Rebuttals Available Digitally for Minimising Biases in Mental Judgements
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 147-156
summary	The problem of heuristic biases (illusions) discussed by Tversky and Kahneman (1982) that can lead to errors in judgement by human designers, when they use precedent knowledge presented graphically (Bay 2001). A Cognitive framework of belief, goal, and decision, and a framework of representation of architectural knowledge by Tzonis are used to map out the problem of heuristic biases in the human mind. These are used to discuss what aspects of knowledge can be presented explicitly and digitally to users to make rebuttal more available for human thinking at the cognitive level. The discussion is applicable to both inductive and analytic digital knowledge systems that use precedent knowledge. This discussion is targeted directly at means of addressing bias in the human mind using digital means. The problem of human bias in machine learning and generalisation are discussed in a different paper, and the problems of international or non-intentional machine bias are not part of discussion in this paper.

title	SPOT! Fetch Light - Interactive navigable 3D visualization of direct sunlight
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 117-124
doi	https://doi.org/10.52842/conf.ecaade.2003.117
summary	SPOT is a 3D environment for direct sunlight visualization. Implemented in Java 3D, SPOT features two distinct and complementary components: Time Projection and Navigable Animation for virtual interaction. SPOT supports multi-dimensional data visualization including sun angle variations with diurnal and annual cycles in threedimensional space. In SPOT users can sketch on any surface in the 3D environment to indicate the area for simulation. SPOT then generates a spatial distribution representation of the illuminance level on a selected surface over time, rendered with colors of varied gradients. SPOT also enables designers to visualize the temporal information of light distribution over time for a given point. For each point clicked on the 3D model, SPOT generates a calendar diagram where the X and Y axis represent the months of the year and the time of the day. The color of each cell of the calendar is the result of the calculation of the light amount reaching the selected point.

title	Shape Generation Using Pareto Genetic Algorithms Integrating Conflicting Design Objectives in Low-Energy Architecture
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 681-694
doi	https://doi.org/10.52842/conf.caadria.2003.681
summary	The Generative Design System [GDS] presented in this paper was developed to assist designers in researching low-energy architecture solutions. The GDS has the capability to evolve architectural forms that are energy-efficient, while complying to design intentions expressed by the architect, and responding to conflicting objectives. To achieve this evolutionary development, the system integrates a search and optimization method [Genetic Algorithm], a building energy simulation software [DOE2.1E], and Pareto multicriteria optimization techniques. The GDS adaptively generates populations of alternative solutions, from an initial schematic layout and a set of rules and constraints designed by the architect to encode design intentions. The two conflicting objective functions considered in this paper are maximizing daylighting use, and minimizing energy consumption for conditioning the building. The GDS generated an uniformly sampled, continuous Pareto front, from which six points were visualized in terms of the proposed architectural solutions.

title	Interaction, Agency and Artefacts
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 249-258
summary	This paper argues (i) that understanding of a place (especially in heritage environments) requires a level of cultural engagement and (ii) that virtual environments, in their typical current form, fail to provide such engagement. A proposed solution to the issue of cultural presence is to apply the interactive mechanisms commonly used in computer games (social agents, levels of interaction constraint, and task-based manipulation of artefacts) to virtual heritage environments. The hypothesis is that the resulting environment will allow for greater engagement and a more culturally immersive learning environment. Virtual environments also often lack techniques for evaluating the extent to which their design goals are achieved. A proposed secondary outcome is that designers and researchers of virtual environment can also use the above interactive mechanisms for the evaluation of user engagement without simultaneously interrupting the user’s feeling of engagement.

title	Architecture as a Reference for the Development of A Cad Lighting Tool
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 281-294
doi	https://doi.org/10.52842/conf.caadria.2003.281
summary	As light is increasingly perceived as a factor of quality of urban life, it is not surprising that cultural heritage buildings and even civil engineering works are being more and more often illuminated at night. The designers of the projects are revealing a nocturnal vision of the buildings which is often a reflection of the architecture: rhythm, pattern, evenness, symmetry, composition, axes, and so on. The idea of developing a "lighting-modeller" is based upon this assertion. Thus, if we express the needs in terms of functionalities, we can conclude that the hierarchical structure of the architectural edifice can fit in with a "lighting-structure". As a result, concepts like hierarchy, linking, grouping, networking, linearity-polarity, are the basis of the objects and functions that are effective for the great majority of buildings and projects. This "lighting-modeller" can then lead beyond its simulation capabilities to become a design conception tool: hypothesis and variants are quickly realized and tested, and technical data (illumination data, visual comfort) can be obtained as well.

title	Right Tools for Designing Free-form Geometry More than Representation and Manipulation
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 433-444
summary	This paper examines what the appropriate strategy for designers to handle the complex object is and how digital and conventional tools are involved in presenting and representing design artefacts for presenting design ideas and deliver design information, particularly in 3D free-form geometry. A series of precedent studies are conducted to examine the argument. The manipulation of digital tools is not merely a technical problem but a strategy about what the right tool for designing geometry is and how design process and principles are innovated. Two demonstrative projects are presented to illustrate how designers can better analyse and define the best choice of medium and design tools, and create a digital design platform to reach the merit of the tools created.

title	AN INCLUSIVE ‘WORK-METHOD’ AND A SPECIFIC SEARCH FOR FULLY SUPPORTED SOLUTIONS THROUGH SUBJECTORIENTED DESIGN (INSTEAD OF OBJECT-ORIENTED)!

summary	This paper talks about the hardness of CAAD.And it talks about the necessity to develop ‘soft’ CAAD.A lot of architectural adventures are stopped in the beginning or the middle of the road. Because of decisions far away from the designers or the clients. These decisions break in against some aspects of the design. Small details often kill a whole design-process.Does architectural design only belong to architects and planners ?To a “Me, myself and I”-world ? For the last 10 years, we have gained a lot of experience of designing architectural landscapes in a specific way. We design in such a way that developing projects can change or evolve strongly within themselves without losing their typical spirit. Change because of external and non-predictable events, change because of unexpected or changing circumstances, change because of the participation of new intervening people….New housing projects in Apeldoorn and Dordrecht,Rehabilitation projects in Gennevilliers (Paris) and Hellersdorf (Berlin), …Schools and hospitals in Amsterdam, …Each time very local aspects are incorporated in the different design-spirits.The networks are similar because of specific design-methods.This paper wants to explain something about this process-spirit.

title	The Use of Virtual Reality in Urban Design: Enhancing the Image of Al-Ain City, UAE
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	This study aims at exploring the rapid growth of the use of Virtual Reality techniques in the field of Urban Design with application to the Al-Ain City. Currently, Virtual Reality and Virtual Environments are the most growing fields of information technology and have a great media attention. There is evidence to suggest that the use of such technology will enhance conceivable image of any proposed project at any urban setting for users, designers and clients. Therefore, city officials and administrators (clients) and the public (users) can reach better decisions regarding proposed projects within their towns and cities. Because of the limited time and resources, this study examines the visual quality of Downtown Al Ain, UAE, specifically, the Khalifa street (major shopping street). A basic VRmodel to the street was constructed. Modifications to the basic model were made to examine how changes in buildings’ heights and street vegetation affect the visual quality of the street. Results of this study showed that urban visualization is proving to be a valuable tool for designers and planners. Increasing the heights of buildings in the mid-street and on the edges, along with enforcing distinctive architectural styles for the proposed buildings will enhance the overall quality of the street. Furthermore, decreasing the intensity of current vegetation and tree heights will increase the imaginable quality of the street. Nevertheless, the built of a comprehend VR model needs more time, resources and facilities that were not available to this study. This model, if completed, tothe whole downtown area can be used both to identify existing problems and to quickly evaluate alternative solutions to those problems.

summary	Describing design as a sequence of steps cannot convey the complexity of social interactions that it embodies. Design is not merely a process, but a co-evolution of efforts and events in various places and times—both synchronous and asynchronous. Designers share their values, effort and expertise within design settings via artifacts that further the design process. Increasingly, these design settings in academia, research, and professional practice combine physical and virtual modalities such as immersion, projection, and a range of interaction technologies. Peter Anders has described such spaces as cybrids: hybrids that integrate virtual and physical space. In these settings, designers use overlapping physical and virtual artifacts and tools to arrive at a co-operative design resolution. Within collaborative design, these artifacts take on an additional role. As embodiments of design ideas and actions, they become media for communication. Donald Schon asserts that design should be considered a form of making, rather than primarily a form of problem solving, information processing or research. Indeed the line separating creation from design is becoming increasingly blurred. For the design artifact itself may become a part of the design proposal—its virtual presence incorporated within a cybrid structure or object. We may in the future see a proliferation of cybrid settings that support collaborative, digital design. The technologies for this already exist in collaborative tools, networked computing, scanning and immersive media. However, it will take a creative vision to see how these disparate tools and devices can integrate within the ideal design setting.

title	Reflections on Computer-Supported Cooperative Design Systems
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 169-180
summary	Computer-supported cooperative work has come to signify a process by which a computer system supports the activities of geographically dispersed participants and enables them to share ideas and artefacts. This paper aims to dispel this unified approach to the definition of and in turn the design of aids to cooperative work. The paper starts by surveying the history of the field of computer-supported cooperative work and design. Then, the paper presents three tasks and their associated aids. The first system helps designers to create and discuss a hierarchical building program and share schematic drawings. The second system allows a jury to anonymously review a set of submissions. The third system allows a hierarchically organised group of participants to search, retrieve, organise and share a set of digital media assets. All systems are web-based and use the same underlying object-oriented technology. The paper provides a brief case study that describes the main features of the three pieces of software as an example of the need for a variety of approaches in the support of cooperative work and design. The paper concludes by advocating an object-oriented, domain-specific approach to creating computer-supported cooperative systems based on the analysis of the task at hand.

title	Tangible Design Media: Toward An Interactive CAD Platform
source	International Journal of Architectural Computing vol. 1 - no. 2
summary	This paper presents an interactive CAD platform that uses a tangible user interface to visualize and modify 3D geometry through manipulation of physical artifacts.The tangible user interface attempts to move away from the commonly used non-intuitive desktop CAD environment to a 3D CAD environment that more accurately mimics traditional desktop drawing and pin-up situations. An important goal is to reduce the apparent complexity of CAD user interfaces and reduce the cognitive load on designers. Opportunities for extending tangible design media toward an interactive CAD platform are discussed.

summary	The advent of the Internet has led us to believe that we live in an era of unprecedented globalization. In the field of building design, we now expect both that the local market for design services will be altered, and that many firms will take up the opportunity to pursue commissions beyond their local market. To some extent this is true, but it is instructive to recall that in the 19th century London based architectural firms and public works designers designed buildings throughout the Empire. Designing for projects beyond the local market is not new, what is new is our expectation that such a task is now fundamentally altered, made easier and more transparent, by the abundance of new communications technologies.It remains the case that working outside one’s local context is difficult and that when doing so, problems are likely to arise out of cultural differences. Distance too imposes its burdens, as the possibility to meet other members of the team face to face is reduced as the travel costs increase. This breaks down the possibilities of building informal networks among the individual designers working for the firms that are members of the design team. A re-instantiation of this informal network can only be done on the basis of a model of formal and informal communication in the design team. Many of the difficulties of collaborative work outside one’s local market are problems that have already been with us a long time. These problems arise out of the fact that buildings are designed by heterogeneous groups of people. The members of such groups must communicate with each other to share information and coordinate decisions and actions. Yet they are in different relations to the project at hand and have differing values arising out of their different backgrounds. This leads inevitably to conflict. Therefore, if we are to discuss communication and value then we must devote our attentions to conflict.

title	Prêt-à-Construire – An Educational Inquiry into Computer Aided Fabrication
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 162-165
summary	This paper aims to show and discuss the relevance of developing necessary strategies for reintegrating the concept of fabrication into the architectural design process. The discussion will be partly based on the outcome of a graduate architectural design studio conducted in Spring semester 2002-2003. The graduate studio was part of a series of exploratory studies conducted on the nature of architectural design process transformed by information technologies. Preceded by studios investigating cognition and representation, this last studio focused on the concept of fabrication. The overarching aim of the studio series was to put CAD and CAM in context both within the actual architectural design process and within architectural education. The last of this series, which will be discussed within the frame of this paper, has specifically focused on CAM and the concept of fabrication in architecture. In accordance with the nature of a design studio, the research was more methodological than technical. The studio derived its main inspiration from the constructional templates used in dressmaking, which can be considered as an initial model for mass customization. In this context, the recladding of Le Corbusier’s Maison Domino was given as the main design problem, along with several methodological constraints. The main constraint was to develop the design idea through constructional drawings instead of representational ones. The students were asked to develop their volumetric ideas through digital 3D CAD models while working out structural solutions on a physical 1/50 model of Maison Domino. There was also a material constraint for the model, where only specified types of non-structural paper could be used. At this stage, origami provided the working model for adding structural strength to sheet materials. The final outcome included the explanation of different surface generation strategies and preliminary design proposals for their subcomponents. The paper will discuss both the utilized methodology and the final outcome along the lines of the issues raised during the studio sessions, some of which could be decisive in the putting into context of CAD – CAM in architectural design process. One such issue is mass customization, that is, the mass production of different specific elements with the help of CAM technologies. Another issue is “open source” design, indicating the possibility of a do-it-yourself architecture, where architecture is coded as information, and its code can be subject to change by different designers. The final key issue is the direct utilization of constructional drawings in the preliminary design phase as opposed to representational ones, which aimed at reminding the designer the final phase of fabrication right from the beginning. Finally, the paper will also point at the problems faced during the conduct of the studio and discuss those in the context of promoting CAM for architectural design and production in countries where there is no actual utilization of these technologies for these purposes yet.

summary	In this paper we present a framework for use in the blue-c, a collaborative telepresence environment. We implemented the framework on top of the blue-c API to enable new ways of designing digital 3D spaces in an immersive way. The framework will be used to support designers in creating spatial scenarios within CAVETM – like environments. It concentrates on the integration aspect of different media and data types. Architectural knowledge and information technology is combined to introduce a new approach for designing virtual environments.

title	A Cognitive Framework of Collaborative Design Between Architects and Manufacturer-Designers
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 855-870

summary	The widespread application of prefabricated products in building has made prefabrication an indispensable part of building processes. In this context, instead of handling every detail by architects themselves, some parts of architectural design have been transferred to manufacturer-designers. This inevitably brings about problems in the integration of prefabricated products and the specific buildings they serve. As a result, collaboration between architects and manufacturer-designers takes place in building processes in various forms and extents (non-, semi-, and full-collaboration). In this study, we aim to investigate collaborative design process from the cognitive aspect of design generation between architects and manufacturer-designers in terms of project-related products design. By applying the Kernel of Conceptual System theory (Tzonis et al., 1978), we intend to set up two empirical models in terms of design differences' formation in collaborative design process based on a case study with seeking the answers for the following research questions: 1. What kinds of design differences are raised in design processes? 2. Why the design differences are raised in design processes? 3. What implications could be made in developing computational models to facilitate collaborative design between architects and manufacturer-designers?

title	G Pen: An Intelligent Designer’s Playmate
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 403-409

summary	In the field of design the pen-based system is a newly developed computer interface that provides the designer with the convenience of a pen in freehand sketches. But these pen-based systems only focus on an interface familiar to the designers and the application of the hardware and software that go with it, treating the pen only as a mouse-like input device. As pen and pad are devices for the pen-based system, the hope is that they can be endowed with more intelligent characteristics to let them interact with designer’s gestures and become a creative source for the designers, while simultaneously preventing the design fixation encountered by designers during design process. This research utilizes the unintentional hand gestures made by designers, such as the designer’s grip of the pen or movement involved in playing with the pen, putting it down, knocking it, twisting it or shaking it, during the thinking process or when running into a design fixation. From the interaction between the pen and the pad, certain actions may be generated to stimulate the designer’s thinking process. This research uses a neural network as the main learning mechanism for the eventual development of a prototype of a pen-based drawing system that provides timely visual stimulation: a G Pen system.

title	Seeing Moving Seeing Model for Computer Media
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 199-208

summary	This paper discusses several kinds of the cognitive seeing and moving actions for designers in traditional and computer media. Experiments are conducted for the protocol analysis, and a coding scheme of seeing and moving actions are applied in this research. The results of this study reveal the relationships between seeing, moving, and concept-getting actions in these two medias. Base on this study, we can figure out the characteristic of seeing and moving actions and make an improvement for design education and computer-aided-design systems.
