title	Integrating Energy Design Into Caad Tools: Theoretical Limits and Potentials
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. 323-340

summary	The study is part of a research aims to establish theoretical grounds essential for the development of user efficient design tools for energy-conscious architectural design, based on theories in human factors of intelligent interfaces, problem solving, and architectural design. It starts by reviewing the shortcomings of the current energy design tools, from both architectural design and human factor points of view. It discusses the issues of energy integration with design from three different points of view: architectural, problem-solving, and human factors. It evaluates theoretically the potentials and limitations of the current approaches and technologies in artificial intelligence toward achieving the notion "integrating energy design knowledge into the design process" in practice and education based on research in the area of problem solving and human factors and usability concerns. The study considers the user interface model that is based on the cognitive approach and can be implemented by the hierarchical structure and the object-oriented model, as a promising direction for future development. That is because this model regards the user as the center of the design tool. However, there are still limitations that require extensive research in both theoretical and implementation directions. At the end, the study concludes by discussing the important points for future research.

summary	The development of architectural design systems that describe fully the form, structure and behaviour of a design relies heavily on the incorporation of intelligence in the representations, analyses, transformations and transactions used by the computer. Traditionally such intelligence takes either of two forms. The first is a methodical framework that guides actions supported by the design system (usually in a top-down fashion). The second is local, intelligence mechanisms that resolve discrete, relatively well-defined subproblems (often with limited if any user intervention). Local intelligent mechanisms offer the means for adaptability and transformability in architectural design systems, including the localization of global tendencies. This refers both to the digital design technologies and to the historical, cultural and contextual modifications of design styles and approaches.

title	Implicit Handling of Geometric Relations in an Existing Modeler
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. 613-622
doi	https://doi.org/10.52842/conf.caadria.2003.613
summary	This paper presents a constraint-based modeling system, integrated into a widely used CAD modeler. Using a notification mechanism, the system records the precision functions called by the user in order to maintain geometric relations between points locations and source objects. These relations are stored in a directed graph which allows an automatic update of the model.

title	Metodología Interdisciplinaria para Diseñar Nuevas Arquitecturas de Representación de Datos (Interdisciplinaria Methodologies for the Design of a New Architectures of Data Representation)
source	SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary	Data representation architecture can be defined as the organizational, functional, experiential, formal, and media-technological order defining the interaction between data, representation, and user. This paper presents an interdisciplinary methodology to develop such architectures in order to significantly improve real time decision making in complex data environments. We have reported in some aspects of this work elsewhere. In this occasion, we will describe our working methodology based on complete interdisciplinarity, the design process and evaluation protocols. We will show work done for Finance and Network Monitoring. Our long-term goal is to design a new generation of data representation architectures that is applicable to diverse fields.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

title	A NEW APPROACH TO THE INTERACTIVE RESOLUTION OF CONFIGURATION PROBLEMS IN VIRTUAL ENVIRONMENTS
source	3rd International Symposium on Smart Graphics, Heidelberg, Germany, 2-4, July 2003. http://www.smartgraphics.org/ . Proceedings published by Springer: Lectures notes in Artificial Intelligence.
summary	Intelligent Virtual Environments integrate AI techniques with 3D real-time environments. As such, they can support interactive problem solving, provided the underlying AI techniques can produce solutions within a time frame matching that of user interaction. In this paper, we describe an intelligent virtual environment based on Constraint Logic Programming (CLP), integrated in a real-time 3D graphic environment. We have developed an event-based ap-proach through which user interaction can be converted in real-time into appro-priate solver queries which are then translated back into automatic reconfigura-tions of the Virtual Environment (VE). Additionally, this framework supports the interactive exploration of the solution space in which alternative solutions (configurations) can be found. We demonstrate the system behaviour on a con-figuration example. This example illustrates how solutions can be interactively refined by the user through direct manipulation of objects in the VE and how the interactive search of alternative solutions in the VE is supported by these type of systems.

title	A NEW APPROACH TO VIRTUAL DESIGN FOR SPATIAL CONFIGURATION PROBLEMS,
source	7th IEEE International Information Visualisation Conference, London, UK, 16-17 July 2003. http://www.graphicslink.demon.co.uk/IV03/
summary	In this paper, we present a new framework for the use of Virtual Reality (VR) in engineering design for configuration applications. Traditional VR systems support the visual exploration of a design solution but do not assist the user in exploring alternative solutions based on domain knowledge. Extending previous work in the area of Intelligent Virtual Environment, we propose an intelligent configuration system based on constraint logic programming (CLP), integrated in a real-time 3D graphic environment. This type of integration facilitates the expression of design knowledge in the VE and enables the user to interactively solve and/or refine a spatial configuration problem. In the system described in this paper, the user can visually explore configurations, but his interaction with objects of the configuration problem triggers new cycles of constraint propagation from the modified configuration to produce a new compatible solution.

source	SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary	This work is a software application where the user will be able to go over a collection of optic art paintings, which are computer generated (they reproduce Victor Vasarely's works style). By selecting two of these paintings, the user will obtain a third one that will inherit their characteristics. The aim of this work is to generate a collection of paintings, which evolve according to the users' taste. For this purpose, we drew the analogies between the genetic evolution of living beings and their natural selection process to adapt themselves to the environment.

title	Interaction, Agency and Artefacts

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	Interactive Mapping between Knowledge Level and Symbol Level with Geometry. A KL-Model for Design Space Exploration
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. 157-166
summary	Design space exploration is long-standing motivating ideas in computer-aided design. It realises this vision through a model of design states for making and moving amongst states and an organisation of states into a structure called a design space. Using a design space structuring mechanism based on a subsumption relation, this paper sketches a theory called Geometric Typed Feature Structures (GTFS) to preserve the formal properties of the design space movement algorithms for geometry. It also provides the theory for incorporation of user-guided exploration in the design space. Consequently, the clear division between knowledge level and symbol level, such that functional decomposition •• formal symbol level and design •• model symbol level, disappears. We can therefore use the same subsumption relation to structure the design space exploration interactively. Such interactive mapping between knowledge level and symbol level provides the fine-grained opportunities for user intervention in formal design space movement algorithms. In this paper, we summarize this approach with an example of GTFS subsumption process.

title	Undo Reinterpreted

doi	https://doi.org/10.52842/conf.acadia.2003.019
summary	The class of operations known as “undo” has proven to be a valuable addition to most professional work tools. In practice though, its use is frustrating: undo often undoes too much. Its essential informal semantics are that it returns the user to a prior state by recapitulating all intervening states. Why not give the user greater control over which aspects of a design to undo? An alternative is to seek to reuse prior work in any logically-coherent pattern—user input is a precious commodity. The area of generative systems provides insights in a search for alternatives to undo, in particular that prior user and system actions can be changed and reused in new contexts. We contingently introduce a concept we label as design promotions to describe system designs that demonstrate a tight coupling between interactive authorship and system-led generation, that treat past user actions as valuable intentional statements, and that treat alternative user choices as first-class objects of concern. In practice these three properties emphasize reuse. We briefly survey the current state of undo-like operations and potential candidates for implementing design promotions strategies. Through examples, we demonstrate approaches to realizing undo-like operations over specific representations, especially that of constructive solid geometry.

title	Integrated 4d Cad and Construction Safety Planning Information for a Better Safety Management
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. 891-904
doi	https://doi.org/10.52842/conf.caadria.2003.891
summary	Safety is an important element of project successes. In the conventional project management, safety planning, as a function, is separated from other functions, such as planning/scheduling function. This separation creates difficulties for engineers to analyze what, when, why and where a safety measure is needed to prevent accidents in a construction activity. Another problem occurs due to the conventional practice of representing project designs using two-dimensional (2D) drawings. In this practice, a user (e.g. an engineer) has to convert the 2D drawings into three-dimensional (3D) mental pictures, and this is a tedious task. If only converting this 2D drawing is a tedious task, combining these 2D drawings with safety planning creates more difficult tasks. In order to address the problems, this paper discusses our research in integrating construction scheduling and safety planning in a 4D environment.

summary	The use of computers in the design of the built environment has reached a watershed. From peripheral devices in the design process, they have in recent years come to take centre stage. An illustration is immediately at hand. Just as the entries to the competition for the Chicago Tribune Tower in 1922 defined the state-of-the-art at the beginning of the twentieth century, we have a similar marker at the end of the century, the competition in 2002 to replace the World Trade Centre towers in Lower Manhattan offered us a range of architectural solutions that exemplified the state-of-the-art eighty years later, setting forth not only architectural statements but also illustrating clearly the importance of computers in the design of the built environment. In these entries of 2002, we can see that computers have not only become essential to the communication of design but in the investigation and generation of structure, form and composition. The papers in this book are the current state-of-the-art in computer-aided design as it stands in 2003. It is the tenth in a series sponsored by the CAAD Futures Foundation, compiled from papers presented at the biennial CAAD Futures Conferences. As a series, the publications have charted the steady progress in developing the theoretical and practical foundations for applications in design practice. This volume continues in that tradition; thus, this book is entitled Digital Design: Research and Practice. The papers are grouped into three major categories, reflecting thrusts of research and practice, namely: Data and information: its organisation, handling and access, including agents; Virtual worlds: their creation, application and interfaces; and Analysis and creation of form and fabric. The editors received 121 abstracts after the initial call for contributions. From these, 61 abstracts were selected for development into complete papers for further review. From these submissions, 39 papers were chosen for inclusion in this publication. These papers show that the field has evolved from theoretical and development concerns to questions of practice in the decade during which this conference has showcased leading work. Questions of theoretical nature remain as the boundaries of our field expand. As design projects have grasped the potentials of computer-aided design, so have they challenged the capabilities of the tools. Papers here address questions in geometric representation and manipulation (Chiu and Chiu; Kocaturk, Veltkamp and Tuncer), topics that may have been considered to be solved. As design practice becomes increasingly knowledge based, better ways of managing, manipulating and accessing the complex wealth of design information becomes more pressing, demanding continuing research in issues such as modelling (Yang; Wang; Zreik et al), data retrieval and querying (Hwang and Choi; Stouffs and Cumming; Zreik, Stouffs, Tuncer, Ozsariyildiz and Beheshti), new modes of perceiving data (Segers; Tan). Tools are needed to manage, mine and create information for creative work, such as agents (Liew and Gero; Smith; Caneparo and Robiglio; Ding et al) or to support design processes (Smith; Chase). Systems for the support and development of designs continue (Gero; Achten and Jessurun). As progress is made on some fronts, such as user interfaces, attention is again turned to previously research areas such as lighting (Jung, Gross and Do; Ng et al; Wittkopf; Chevier; Glaser, Do and Tai) or services (Garcia; Chen and Lin). In recent years the growth of connectivity has led to a rapid growth in collaborative experience and understanding of the opportunities and issues continues to mature (Jabi; Dave; Zamenopoulos and Alexiou). Increasing interest is given to implications in practice and education (Dave; Oxman; Caneparo, Grassi and Giretti). Topics new to this conference are in the area of design to production or manufacture (Fischer, Burry and Frazer; Shih). Three additional invited papers (Rekimoto; Liu; Kalay) provide clear indication that there is still room to develop new spatial concepts and computer augmented environments for design. In conclusion, we note that these papers represent a good record of the current state of the evolving research in the field of digital design.

title	The Tangible Interface: Experiments as an Integral Part of a Research Strategy
source	International Journal of Architectural Computing vol. 1 - no. 2
summary	The Human-Computer interface is crucial to good design support tools. It has to be non-interruptive and non-distracting, yet allow the architect to interact with the computer software. The physical reality of the interface, such as the shape and manipulability of devices like the mouse, keyboard, joystick, or data-glove, has to be mapped on actions and commands in the software. Already the current user interfaces are felt to be inadequate for a good support of design, and the functionality of design tools is growing, requiring even more and new physical interface devices. In this paper, we present research on new tangible interfaces for architectural design support. In particular, we focus on the research methodological question how to investigate such devices.The research strategy is introduced and discussed, after which concrete implementations of this strategy are shown. Based on this work, we conclude that the combination of interface and the context of its use in terms of design method and user needs form crucial aspects for such research and cannot be considered separately.

summary	The ultimate goal of the described research is a process for mass customizing housing based on computer-aided design and production systems. The current goal is the development of an interactive system for generating solutions on the Web based on a modeling approach called discursive grammar. A discursive grammar consists of a programming grammar and a designing grammar. The programming grammar generates design briefs based on user data; the designing grammar provides the rules for generating designs in a particular style, and a set of heuristics guides the generation of designs towards a solution that matches the design brief. This paper describes the designing grammar using Siza´s houses at Malagueira as a case study.

summary	The aim of this study was to examine the feasibility of virtual reality (VR) technology for use by persons with dementia (PWD). Data were obtained directly from six PWD regarding their experiences with a virtual environment (VE) of a large outdoor park. A user-centered method was developed to assess: (a) presence; (b) user inputs; (c) display quality; (d) simulation fidelity; and (e) overall system usability. The extent to which PWD could perform four functional activities in the VE was also investigated (e.g., mailing a letter). In addition, physical and psychological well-being of PWD while interacting with the VE was assessed objectively by recording heart rate during the VR sessions and subjectively with discrete questionnaire items and real-time prompts. Symptom profiles associated with simulator sickness were assessed with an adapted version of the Simulator Sickness Questionnaire. The study found that PWD to some extent experienced presence; perceived that objects were realistic and moved naturally; generally felt in control of the interaction; and demonstrated little difficulty using a joystick for navigation. The study also demonstrated that VR is an appropriate medium for assessing functional behavior within the context of an ecologically valid VE. PWD did not experience any significant increase in symptoms associated with simulator sickness, or detriments to their psychological and physical well-being. These findings demonstrated that it is feasible to work in VEs with PWD.
