Moloney, Jules. "A Framework for the Design of Kinetic Façades." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 461-474. CAAD Futures. Dordrecht: Springer, 2007. The particular requirements of kinetic façades are discussed in relation to a general model for future CAAD research - a 3D digital prototype based on (1) the concurrent evaluation of quantitative and qualitative performance over time (2) the calibration of geometry and physics to materiality and mechanics. Concurrent performance in the case of kinetic façades is determined by the dual role as environmental screens and the socio-cultural function as the public face of architecture. From these principles a framework is proposed that informs the conceptualisation of software that will address unique requirements - the design of façades as process systems that perform over a range of time scales.
Ryu, Jaeho, and Ryuzo Ohno. "A Novel Room Re-Layout Design Tool for Preparedness of Earthquake Disaster Using Real-Time Physics Simulation and Force-Feedback Interface." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 541-554. CAAD Futures. Dordrecht: Springer, 2007. The virtual reality (VR) generated by computer graphics (CG) has developed very rapidly in accordance with the rapid improvement of computer hardware and CG algorithms. Not only visual still images but also the representation of the behaviour of virtual objects has became possible owing to real-time physics simulation, which can provide a high sense of presence to users. Adopting the real-time physics simulation and the force-feedback interface to the architectural design process in VR could make it more realistic by providing a sense of virtual objects such as the weight of the mass, tactile sensation, and interaction between virtual objects and users. As a pilot application of real-time physics simulation and the force-feedback interface in the architectural field, we are developing an educational VR system for earthquake disaster preparedness through a room re-layout design process.

In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 265-278. CAAD Futures. Dordrecht: Springer, 2007. This paper proposes a simple parametric system to generate an almost complete set of ruled surfaces that may be used to describe building geometry. The major classes of regular, named ruled surfaces can be generated from a limited set of curves. Each of these is shown to be reducible to a transformation of a single standard curve, a helix, and therefore represented by a limited set of six parameters. Six extra parameters can position each surface on a global coordinate system. The representation is designed to be flexible enough to represent both planar and curvilinear forms, producing a description of form from minimal data. 
Benros, Deborah, José Duarte, and Fernando Branco. "A System for Providing Customized Housing." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 153-166. CAAD Futures. Dordrecht: Springer, 2007. This paper describes a system for generating customized mass housing. The aim is to provide dwellings at an affordable cost with recourse to mass production and yet guarantee that they are tailored to their users. It combines two systems, a rule-based design system and a prefabricated building system. The integration of both systems is achieved through the development of a computer tool to assist designers in the various stages of the housing design process. This tool produces three kinds of outputs: three dimensional models, construction drawings, and a list of construction elements, including their cost and information for manufacturing.
Moere, Andrew. "Aesthetic Data Visualization as a Resource for Educating Creative Design." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 71-84. CAAD Futures. Dordrecht: Springer, 2007. Data visualization is usually considered an expert field reserved for the computer science or data analysis specialist. In contrast, in this paper we argue that the approaches and theories from data visualization can form a rich contextual resource for teaching creative design principles to students. A conceptual data mapping model is proposed that describes a continuum between “traditional” data visualization applications and more artistically inclined works of “visualization art”. This model is useful to clarify conceptual relationships between different visualization design approaches, ranging from traditional data representation applications over to ambient displays to visualization art experiences. This exchange of insights from related scientific and artistic fields forms the foundation for potential collaboration initiatives in research or educational contexts. Subsequently, this aesthetic data visualization model is explained and illustrated by various student works accomplished in several creative design visualization course units.
Herr, Christiane, and Justyna Karakiewicz. "ALGOGRAM: Automated Diagrams for an Architectural Design Studio." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 167-180. CAAD Futures. Dordrecht: Springer, 2007. Building on a previously presented theoretical model for the integration of cellular automata into the design process, this paper introduces cellular automata as architectural design process support in the form of automated conceptual diagrams. This approach is the outcome of a series of successive software implementations, which are briefly outlined in terms of key features and observations made during their applications. The main part of the paper focuses on Algogram, the latest implementation, and its application in a second year design studio. The integrated concept of abstract representations, automated design exploration and individual interpretation is introduced as automated diagram.
Seichter, Hartmut. "Augmented Reality and Tangible Interfaces in Collaborative Urban Design." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 16-Mar. CAAD Futures. Dordrecht: Springer, 2007. This paper outlines the design, execution and analysis of a user evaluation experiment using Augmented Reality (AR) in an urban design studio. The aim of the experiment was to gauge the differences between two interfaces in regard to their impact on the design process. The two conditions of the experiment were a direct manipulating tangible user interface and a pen-like 3D manipulation interface. Findings include differences in perceived object presence, performance measures, perceived performance and variations in the communication patterns. These findings have implications for the integration of this technology in a praxis relevant design work flow.
Tsai, Hung-Cheng, Chia-Young Hung, and Fei-Kung Hung. "Automatic Product Color Design Using Genetic Searching." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 513-524. CAAD Futures. Dordrecht: Springer, 2007. Color plays a key role in determining a consumer's response to a product appearance. A gray-theory-based linguistic evaluation method and a color-harmony-based aesthetic evaluation method are combined in this study to diagnose appropriate product-color schemes. Accordingly, this study develops a RGB-based quantitative aesthetic and linguistic measurement scheme to evaluate the image perception of a particular product-color scheme. In an inverse process, genetic algorithms are applied to search for the near-optimal color combination which satisfies the designeris specified product-color linguistic evaluation goal and achieves a high degree of color harmony.

In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 361-372. CAAD Futures. Dordrecht: Springer, 2007. The lack of understanding of the character essence of avatars brings about limitations in interaction with their expressions. With the state-of-the art CAD standard and virtual reality, our approach is to explore the different paradigm of virtual architecture focusing on social interaction through avatarsi gesture expression. The method to classify context-aware expression data model and to autonomously activate it in real-time along with users communication is investigated. A domain of virtual office has been chosen as our study model based on our previous research. To achieve our goals, an avatar expression agent is developed based on our previous context-aware architectural simulation platform so called “V-PlaceSims”. The output is delivered as a Web page with an ActiveX control embedded to simulate and to evaluate through the internet. As users communicate with one another using a text box, the avatar expression agent simultaneously detects the usersi emotion by parsing the input texts to perform related gestures automatically. The result reveals a new convenience way to communicate with the other users with an enhancement in automated expression.
Peng, Wei, and John S. Gero. "Computer-Aided Design Tools that Adapt." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 417-430. CAAD Futures. Dordrecht: Springer, 2007. This paper describes an approach that enables a computer-aided design tool to learn conceptual knowledge as it is being used, and as a consequence adapts its behaviours to the changing environment. This allows the tool to improve the effectiveness of designers in their design tasks over time. Design experiments evaluate the effectiveness of this prototype system in recognizing optimization problems in heterogeneous design scenarios.
Huang, Chih-Chieh. "Conceptual Modeling Environment (COMOEN)." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 31-43. CAAD Futures. Dordrecht: Springer, 2007. Conceptual modelling is an actively creative stage in a design process. Through hand modelling and manipulation of different kinds of modelling tool kits for specific materials, designers are able to generate forms. This article presents a tangible human-computer interface of a C-StressBall for form manipulation and a C-BenchWhirler for visual control. They create a new way of interaction between the virtual world and the physical space. They are aimed to ease the operation in design process by using CAD.
Mitchell, John, Justin Wong, and Jim Plume. "Design Collaboration Using IFC." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 317-329. CAAD Futures. Dordrecht: Springer, 2007. This paper reports a study that has been undertaken as part of an on-going project to examine the capacity of building information modelling (BIM) techniques to support collaborative design in the building industry. In particular, our premise is that effective design collaboration relies on the ability to exchange BIM data in a robust way using an open information standard such as IFC. The focus of this present work has been on the processes involved in design collaboration between architects and engineers responsible for advising on thermal performance issues.  We begin by looking at the kinds of data that needs to be exchanged to support such collaboration.  We then test the exchange using a pilot project model and finally review the capacity of the IFC standard to support such processes.
Hirschberg, Urs, and Michael Stadler. "Design Science Labs: Why architectural research needs laboratories for integrated and networked simulation." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 475-488. CAAD Futures. Dordrecht: Springer, 2007. The ever increasing complexity of architectural projects demands efficient tools to assist within their associated design processes. We present an infrastructure initiative to tackle these challenges with Design Science Labs that are heavily rooted on simulation techniques in various academic fields. The merits of these techniques are discussed under the prospect of research and teaching experience as well as practical applicability. For an increased benefit, strong interoperability between these simulation techniques is desirable, but still not easily achievable. The infrastructure initiative aims to build smooth bridges between these fields and to gain additional architectural design space from their interaction.
Smith, Greg, Ning Gu, and Mary Lou Maher. "Designing Virtual Worlds for 3D Electronic Institutions." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 387-400. CAAD Futures. Dordrecht: Springer, 2007. 3D Electronic Institutions (3DEI) are 3D virtual worlds that are dynamically designed in response to the usersi needs and the rules of an electronic institution. Electronic institutions can be modelled as multi-agent systems inspired by analogous physical institutions. This paper describes coupling of a multi-user 3D virtual world to an electronic institution. The resulting 3DEI is a distributed and heterogeneous multi-agent system that provides the advantages of both with the organizational structures imposed by the electronic institutions and the spatial characteristics provided by 3D virtual worlds. 
Holzer, Dominik, Yamin Tengono, and Steven Downing. "Developing a Framework for Linking Design Intelligence from Multiple Professions in the AEC Industry." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 303-316. CAAD Futures. Dordrecht: Springer, 2007. The research presented in this paper addresses the issue of bridging conceptual differences between the theories and practice of various disciplines in the AEC industry.  The authors propose an application logic that works as a framework in assisting the evaluation process of multidisciplinary design. Parametric design templates assist in channeling and integrating information generated during the design process.
Stavric, Milena, Heimo Schimek, and Albert Wiltsche. "Didactical Integration of Analog and Digital Tools into Architectural Education." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 61-70. CAAD Futures. Dordrecht: Springer, 2007. This paper describes the new syllabus of the course “Methods of representationi that has evolved in the first year of architectural study at our university. Due to the rapidly growing digital possibilities students need to know/learn the new topics and tools which are relevant in modern architectural design practice. Our students should be empowered rather than overwhelmed by the arsenal of digital tools available today. In this course we try to define the essential skills in representation which we achieve through the synthesis of digital and analog methods and tools. Digital and analog methods and tools we use are: study and construction of complex geometry, observation and analysis of organic forms and their representation through hand drawing, collaborative work through peer-to-peer learning on our web interface, NURBS-modelling, rapid prototyping and desktop publishing.
Mahalingam, Ganapathy. "Discovering Computational Structures in Architecture." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 129-137. CAAD Futures. Dordrecht: Springer, 2007. The linkage between the worlds of Architecture, which involves the design and construction of the built environment, and Computer Technology, which involves practical applications of computation, still has a vast, as yet untapped potential. What if the implications of the linked term, “computer-architecture,” are explored to reveal its full scope? This paper describes a unique method to analyze and code works of Architecture in a way that enables one to discover hidden computational structures in the works of Architecture. The case being made here is that the inherent structures of architecture may be computational structures as well.
Chan, Chiu-Shui. "Does Color Have Weaker Impact on Human Cognition than Material?" In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 373-384. CAAD Futures. Dordrecht: Springer, 2007. This project intends to develop a method for using virtual reality (VR) to represent a built environment for simulating environmental influences on occupants. Objectives of the project were to explore: (1) what environmental stimuli would affect habitants perception, and (2) what possible factors in the built environment would affect occupants cognition. An office was selected as the subject of study. Methods were to create a number of digital models, each containing an embedded variable, and then test the impact of environmental influences on visual perception. Results obtained in this study indicate that materials have stronger impact to human perception than colors, and VR has great potential for design decision making and post-occupancy evaluation.
Penttila, Hannu, and Hannu Penttillä. "Early Architectural Design and BIM." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 291-302. CAAD Futures. Dordrecht: Springer, 2007. This paper examines the meaning of information and communication technology (ICT) for architectural design in early design project phases, with a particular interest in building information modelling (BIM). Contemporary digital design environment, research context and objectives are first clarified, followed by the presentation and analysis of a few BIM-related projects. A key finding is that the architectural working environment, the design methods and the designer's roles have changed in the contemporary project context. Furthermore, other methods and tools are needed in addition to BIM in the early project phases, because it can not solve all required design aspects.
Fischer, Thomas. "Enablement or Restriction? on supporting others in making (sense of things)." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 585-598. CAAD Futures. Dordrecht: Springer, 2007. In this paper I present and reflect upon a five-year investigation of designing digital tools for designing in the area of architectural space grid structures. I understand design as a novelty and knowledge generating conversational process as described by Pask (see Scott 2001) and Glanville (2000). Furthermore, I regard making design tools as a design task in itself, rendering this paper a reflection on designing for designing. This paper gives a report on observations I made during the toolmaking study, and subsequently contextualizes these observations using second-order cybernetic theory. This reflection focuses on different relationships between observers and systems, on conditions under which observers construct knowledge and on limits of supporting others in this activity.
Maher, Mary Lou, Kathryn Merrick, and Robert Saunders. "From Passive to Proactive Design Elements." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 447-460. CAAD Futures. Dordrecht: Springer, 2007. Agent technology has been used as an organising mechanism for software systems that focus on modularity and autonomy. This paper presents two applications that explore the potential of combining agent technologies with physical building design elements to change the nature of the built environment from a passive space to one that proactively engages with its inhabitants. We focus on how these curious places sense the state of the environment and the activities of the humans in the environment and enhance the human experience, thus going beyond the concept of supporting human activities in traditional approaches to intelligent rooms. 
Chen, Zi-Ru. "How to Improve Creativity: Can designers improve their design creativity by using conventional and digital media simultaneously?" In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 571-583. CAAD Futures. Dordrecht: Springer, 2007. From previous works, we know that the distinguishing characteristics of design media cause different influence on design creativity. However, the cognitive research about the application of conceptual sketches design by integrating both conventional and digital media simultaneously is absent. In this research, we would like to discuss that can it inspire more creative works if designers use conventional and digital media simultaneously as sketching media to generate conceptual sketches. The results show that using conventional and digital media simultaneously comparing with only using individual media can help arouse creative thinking, cognitive activity and design outcome in the stage of conceptual sketches design. The findings may suggest that the integration of various design media provides one feasible ways to inspire creativity, which can apply to the design training of creativity on education and to the designeris practical operation, but initiates more possibility of new media to assist design.
Lai, Ih-Cheng. "Idea Hitchhiking in the Idea Association Process." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 557-570. CAAD Futures. Dordrecht: Springer, 2007. Idea association is an important behaviour to generate diverse ideas during the conceptual design stage. In the idea association process, the designer links and generates related ideas in conjunction with other participants by idea hitchhiking. By looking for combinations, more novel and useful ideas are found. For understanding how ideas are hitchhiked and combined, we apply a computational tool called DIM and conduct a design experiment to approach this research. Through the analysis of the generated graph-like structure (called idea map), some observations are found and discussed in this paper.

In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 431-443. CAAD Futures. Dordrecht: Springer, 2007. The gaming industry plays a pivotal role in creating real-time advanced shaders nowadays. With better and more affordable computer hardware, shaders are beginning to be used in other non- gaming softwares. The virtual reality visualization tools used by the architectural designers can benefit from this. This paper investigates the impact of real-time shaders on the performance of architectural virtual reality visualization of 3D models and provides a guide for architectural users to decide the optimal number of shaders to use based on the size of the model.

In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 525-539. CAAD Futures. Dordrecht: Springer, 2007. This paper examines how camera movement interprets architectural space and describes a navigation system that is designed to facilitate real time path planning and control of camera movement. The navigation system also allows people to save and retrieve walkthrough paths and thus enables different interpretations of the space by different observers to coexist in the same space. With case studies, we demonstrate that whether a space appears intelligible or unintelligible may be manipulated in the way how the space is interpreted through camera movement.
Iordanova, Ivanka, Temy Tidafi, and Giovanni De Paoli. "Is a Digital Model Worth a Thousand Pictures?" In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 85-98. CAAD Futures. Dordrecht: Springer, 2007. This communication addresses the use of a new type of referents database in the context of an architectural design studio. It discusses the results of design experiences held with the objective to study the cognitive effects of a teaching approach based on precedents and metaphors available as interactive and reusable digital models to students. The introduction of this referent-based approach is inspired by three major principles: the largely accepted fact that the creative work of architects is highly supported by referring to precedents and metaphors, the use of algorithmic digital methods to encapsulate architectural knowledge, and the constructivist approach to architectural design education. The study finds that the role of the modeled referents is helpful for the design studio learning, and that they are most creatively used when internalized by the student.
zkar, Mine Ö.. "Learning by Doing in the Age of Design Computation." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 99-112. CAAD Futures. Dordrecht: Springer, 2007. A design teaching approach of integrating the notions of design thinking and computing in the first year of architectural design education is introduced and discussed. The approach aims to enhance and bring up-to-date the educational practice of “learning by doing” in the first year foundations curriculum. In the studied example, the analytical phases of thinking in a simple design task are systematically and visually recorded. This documentation is incorporated to the design process as a means for the students to consciously reflect on their design thinking. 
Chen, Yingjie, Zhenyu Qian, and Robert F. Woodbury. "Local Navigation Can Reveal Implicit Relations." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 403-416. CAAD Futures. Dordrecht: Springer, 2007. This paper intends to analyze, compare, understand and explore the data relations among a collection, the collected items and user-created meaning appearing in different digital applications. Details of such relations are introduced and investigated with reference to several actual systems. In order to represent these three components in a way easy for users to interpret, navigate and interact, we introduce NEAR, a localized graph visualization tool to help people browse, understand and manipulate information in a digital architectural repository A•VI•RE. 
Marques, Davis, and Robert F. Woodbury. "Managing Contingency in Parametric Models through Implicit Relational Modeling." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 279-288. CAAD Futures. Dordrecht: Springer, 2007. Modelling and maintaining relationships in a parametric model compounds the work of the designer. When major changes in design direction take place, the work invested in the modeled relations is often lost. We contend that an implicit relational modelling approach provides for loosely coupled relations between the'parts'of a design and mitigates the loss of work that occurs when changes take place. In our implemented system, implicit relations participate in a pattern of interaction known as the Dynamic Proxy.
Sun, Chengyu, Bauke DeVries, and Jan Dijkstra. "Measuring Human Behaviour Using Head-Cave." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 501-511. CAAD Futures. Dordrecht: Springer, 2007. In this research funded by NSFC (50408038), an agent-based simulation model is developed for the human evacuation behaviour determined by a list of so-called architectural clues in the environment. A research method is introduced with an application for one of these clue types called Doorway. A six-variable model and a related set of virtual scenes were constructed and implemented in a Head-CAVE system, in which 102 subjects were tested as in an evacuation game. With the binary logit regression analysis a utility function is estimated indicating how these variables affect human choice on any pair of doorways in a scene. Evidence was found that the distance from the decision point to the doorway is not always the most important factor as it is assumed in the other evacuation models.
Diniz, Nancy, Cesar Branco, Miguel Dias, and Alasdair Turner. "Morphosis: a responsive membrane." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 489-498. CAAD Futures. Dordrecht: Springer, 2007. In this paper, we introduce Morphosis: A Responsive Membrane, which physically responds to movement, light and sound interacting spatially and temporally with the environment and their inhabitants. The fundamental hypothesis is to create architectural systems as living, evolving materials. The dynamic of the material is produced by dozens of actuators made by Shape Memory Alloys (SMAs) and LED is which react in real time to change the behaviour of the membrane. The system is controlled by a genetic algorithm in an attempt to develop a technological approach to performance skins that possess adaptive and evolutionary personality relative to changing phenomena of the environment of buildings. 
Wang, Xiangyu. "Mutually Augmented Virtual Environments for Architectural Design and Collaboration." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 17-29. CAAD Futures. Dordrecht: Springer, 2007. Augmented Reality (AR) augments real environment by means of virtual objects and Augmented Virtuality (AV) augments virtual environment with the insertion of real entities. Current AR and AV systems exist independently. This paper proposes a novel concept - Mutual Augmentation (MA) where AR and AV co-exist to form a seamlessly integrated mega-space by sharing certain real/virtual entity. This paper presents a systematic framework of exploring MA for supporting collaboration, communication, and coordination in architectural design beyond traditional single real/virtual space. It also opens up a key direction for future research into Collaborative Virtual Environments, AR and AV.
Schnabel, Marc Aurel. "Parametric Designing in Architecture." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 237-250. CAAD Futures. Dordrecht: Springer, 2007. Parametric design techniques offer obvious advantages for engineering and manufacturing processes, now architects emerge to apply these methods in their creation of design suggesting solutions at an earlier stage of the process. Through the coupling of architectural design with parametric modelling methods, the paper presents novel techniques that enhance architects'contribution to building processes based on parametric design creation. This allows a deeper comprehension of the design objectives and aids designers in their decisions to find solutions.
Rosenman, Michael, and Nicholas Preema. "Plastic Surgery in the Evolutionary Design of Spatial Form." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 139-152. CAAD Futures. Dordrecht: Springer, 2007. This paper presents a methodology for producing good solutions for spatial form for non-routine design more efficiently. The methodology is based on augmenting a conventional evolutionary design approach with a method for improving suboptimal design solutions using domain-specific knowledge. This approach is based conceptually on the practice of plastic surgery, i.e. making minor adjustments to an entity, based on some desired qualities. While a conventional evolutionary design approach can produce reasonably good design solutions in an environment of knowledge uncertainty, plastic surgery, using domain-specific knowledge to manipulate the phenotype, can further improve such solutions in an efficient manner. This paper demonstrates how such a technique can be applied to the generation of spatial form.
Hirschberg, Urs, Martin Frühwirth, and Stefan Zedlacher. "Puppeteering Architecture: Experimenting with 3D gestural design interfaces." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 223-234. CAAD Futures. Dordrecht: Springer, 2007. This paper documents and analyzes a set of experimental prototype applications for interaction with 3D modelling software through body movements. The documented applications are the result of two workshops dedicated to exploring the potential of 3D motion tracking technology in architectural design. The larger issue the work addresses is how one can create tools that allow us to bring our intuition and our talent for “crafti into the digital design process and in how far tapping into the expressive powers of our body movements may provide new possibilities in this respect.
Kaga, Atsuko, Masahiro Kawaguchi, and Tomohiro Fukuda. "Simulation of an Historic Building Using a Tablet MR System." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 45-58. CAAD Futures. Dordrecht: Springer, 2007. To depict characteristics of historical buildings, digital archives must display visual information about structures and their construction. This study defines the components used for three-dimensional (3D) models of framework construction. Framework construction has heretofore portrayed structures through animation using VHS or Hi-Vision video. This paper describes a method to facilitate exhibition through interactive simulation using animation and real-time images. Furthermore, a Tablet MR can be used as an effective simulation tool for studying historical buildings in on-site models. For education about historical wooden-framework architecture, increased interactive potential according to usersi needs will be increasingly necessary.
Zedlacher, Stefan. "Spacensing: a new method sensitizing users and their interactive environments." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 211-222. CAAD Futures. Dordrecht: Springer, 2007. In this article we introduce the research on finding solutions using a 3D motion capture system for architectural design purpose by sensitizing a physical space and its virtual counterpart for user interaction and human motion input. We separate this use in four major steps to get a deeper understanding about the processes of space perception and space constitution in architectural (design) tasks. With detailed information about the manner of movement and the structured workflow it is possible to get new insights into space interaction. Furthermore spacensing provides a toolbox for users to investigate virtual space conditions as well as it allows to draw out conclusions on space sociological assumptions. 
Grasl, Thomas, and Athanassios Economou. "Spatial Similarity Metrics: Graph theoretic distance measurement and floor plan abstraction." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 251-263. CAAD Futures. Dordrecht: Springer, 2007. Comparing space allocation programs computationally is a resource intensive task. This paper introduces a method which reduces the complexity of floor plan graphs to facilitate the problem. In a first step the nodes are labeled according to a laid out classification scheme. This in its own right reduces the complexity of the comparison by introducing more diversity among the nodes. Subsequently the graph can be coarsened in several steps based on the category information. This does not only further reduce the necessary computation, but can also offer a visualization of and additional insight into the essential structure of the space allocation program at hand.

In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 331-344. CAAD Futures. Dordrecht: Springer, 2007. The publicly and privately funded national R&D program “Digital Construction” was initiated in 2003 in order to establish a common platform for interchanging digital information and to stimulate digital integration in the Danish building industry. This paper explores the relation between visions, strategies and tools formulated in the “Digital Construction” program, and the first experiences made from implementing the 3D work method part of the program in an ongoing building project. The discussions in the paper are placed in the complex field between choosing strategies for integrating information and communication technologies on national level, and the effects of these strategies on real life building projects.
Whiting, Emily, Jonathan Battat, and Seth Teller. "Topology of Urban Environments: Graph construction from multi-building floor plan data." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 115-128. CAAD Futures. Dordrecht: Springer, 2007. This paper introduces a practical approach to constructing a hybrid 3D metrical-topological model of a university campus or other extended urban region from labeled 2D floor plan geometry. An exhaustive classification of adjacency types is provided for a typical infrastructure, including roads, walkways, green-space, and detailed indoor spaces. We extend traditional lineal techniques to 2D open spaces, incorporating changes in elevation. We demonstrate our technique on a dataset of approximately 160 buildings, 800 floors, and 44,000 spaces spanning indoor and outdoor areas. Finally, we describe MITquest, a web application that generates efficient walking routes.

In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 197-210. CAAD Futures. Dordrecht: Springer, 2007. This paper investigates the relationships between conventional modes of architectural design, those represented through and mediated by Cartesian schema, and the radical organization of spatial experience available through the use of NURBS modelling. This is examined particularly through a study of how game engine software and the appropriate editors are able to accommodate the properties of both. Within this software the first-person view attempts to provide a normalised experience of the VR environment (usually a game), yet there is significant scope for experiencing radically “other” spatial and topological presences. Whilst considerable work has been done in the use of participatory digital spaces, there is the opportunity for examining the manner in which a highly stylised medium such as Unreal Tournament can productively assist the architectural design process.
Caneparo, Luca, Mattia Collo, Alfonso Montuori, and Stefano Pensa. "Urban Generator." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 347-360. CAAD Futures. Dordrecht: Springer, 2007. The paper presents an ongoing project to interactively simulate urban and regional dynamics at the building scale. Urban Generator is a system for generating a large number of design solutions and for browsing, searching and structuring the high-dimensional space of the design solutions further to variable and customisable factors defined by the designer. The number of these factors is recognised as large, furthermore they are often ill-defined. Urban Generator does not model every factor, instead it supports the designer in defining the significant factors and their interconnections, then freely exploring the dimensions of the space of the design solutions generated by the system.
Koutamanis, Alexander. "Use of a Mobile Architectural Guide." In Computer-Aided Architectural Design Futures 2007: Proceedings of the 12th International CAAD Futures Conference, 183-195. CAAD Futures. Dordrecht: Springer, 2007. A mobile architectural guide assists architectural tourists in selecting, navigating to and recognizing architectural sights. The guide supports such tasks by means of domain knowledge, design documentation and contextual information organized into navigation modules, architectural information systems and learning modules.
