summary	Several commercial real-estate sites provide listings of available commercial property on the Internet. These listings are generated on the basis of selection criteria as floor area, price and location. Despite the obvious utility of the listings and their promise for the transaction process and market transparency, one third of commercial realestate listing sites went bankrupt in 2001 and 2002. To provide an explanation for the failure, 63 commercial real-estate sites were analysed and classified into three basic business models: the Research / Information model, the Marketing model and the Transaction model. A common success factor for all models is the functionality of the site, especially interaction between the user and the available information. The paper proposes that the transfer of existing architectural representations, information-processing instruments and decision-taking tools is an essential component of future development towards integrated services that accompany a building throughout its lifecycle. This transfer amounts to (1) the addition of building and contextual information from standard documentation and online information services, (2) the derivation and coherent description of programmatic requirements database, and (3) advanced user interaction with building information.

title	Cynergies: Technologies that Hybridize Physical and Cyberspaces
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. 289-297
doi	https://doi.org/10.52842/conf.acadia.2003.289
summary	This paper presents ways in which cybrids depend for their technology upon three existing models of architectural hybrid: display space, environmental computing, and augmented/mixed reality. Cybrids bring these techniques together into a synergistic whole that depends as much on the observer for its consistency as it does on its comprising technologies. This synergy is a product of corroborative behavior between different modes, which provide cybrid users with a coherent social/spatial experience. The paper notes cybrids’ similarity to theater, not only for their technological dependency, but also for the tacit yet vital role of the observer in their effect.

title	Modeling of Activities: an approach to the virtual representation of human behaviors in architectural spaces tested in emergency units
source	International Journal of Architectural Computing vol. 1 - no. 3
summary	Despite the increasing interest in the functionality and humanization of architecture, there are few studies covering the occupation of buildings and methods to represent activities in spaces. This article explores new software for simulating and virtual modeling in order to facilitate the analysis and visualization of events in buildings. Of particular importance is programming the behavior of 3D-characters according to the probabilistic evolution of activities, and producing animations and interactive models. This approach was tested in a study of three emergency units of hospitals in Chile. Although a full integration of software was not possible, the process developed (in particular the subjective tours) demonstrated that the technique can provide new information about the functioning and spatiality of the units. In addition, it suggested operative and architectural improvements supporting the management and design of facilities.

title	Visual and Sonic Communication Representations to Support Design Interaction
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. 29-42

summary	Interaction between collaborating parties exerts strong and surprising forces on the design process and thus its outcomes. Hence, there is much to be gained by investigating the nature of these communications. By definition, an organisation establishes clear protocols to realise effective communication, and does so in response to business needs. In contrast, creative endeavours must often harness loose teams of specialised individuals, working in different contexts, disciplines, and language bases, and relying on nonformalised yet highly selective exchanges of information. It is therefore a considerable challenge to comprehend and improve these processes. One approach is to exploit the discrete information contained within digital communications to produce models of these complex conditions. This paper reports preliminary work to identify the components of an email visualisation system. The goal is to apprehend developing structures, providing the collective with the capacity for reflection.

title	Situated Computing A New Paradigm for Design Computing
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. 579-590
doi	https://doi.org/10.52842/conf.caadria.2003.579
summary	This paper introduces the concepts of situatedness and constructive memory as the foundations of situated computing. The difference is between encoding all knowledge prior to its use and allowing the knowledge to be developed and grounded in the interaction between the external world and the designer/tool. The paper elaborates these concepts and concludes with a discussion of the implication of situated computing on computational models of designing and on the development of adaptive design tools.

title	The Role of CAD in Environmental Building Science

doi	https://doi.org/10.52842/conf.caadria.2003.487
summary	The fundamental requirement of all building design is the provision of shelter from the external climate and, if possible, the modification of environmental factors generated by this climate to create an internal environment suitable for human comfort. The environmental design strategies of modifying climate derive from the requirements of creating human comfort in buildings, using the elements of the natural climate which vary throughout the year depending upon the prevailing climatic conditions. Environmental Building Science (EBS) research and practice has investigated various techniques to increase architects' performance in environmental building design. These technical design options are also available to architects to take advantage of the external environment. Most environmental design techniques rely on convectional forms of passive environmental design, and building material and system. But it hardly begins to address the more complex demands of environmental building design issues in the buildings. Particularly, testing environmental design techniques against physical models requires much input data which is not available in the early design stages, and is time consuming to use. This forces architects to work with many design parameters that are not compatible with their activities. It is consequently difficult to observe the interrelation of design techniques with design development. The most important role of Computer Aided Design (CAD) is to integrate wider varieties of input data requirements, modelling with EBS properties, output representations with EBS knowledge and assistance tools for optimisation tasks in environmental design issues.

title	Querying Design Information through Visual Manipulation of Representational Structures
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. 41-52
summary	Querying design information is an intricate aspect of the design process. Supporting arbitrary design queries requires both flexible design information models that can be modified and geared to the kind of question, and access to information in a uniform and consistent manner. We report on an active research effort to provide a 3D graphical interface for the manipulation of representational and data structures in terms of composition and scope. It is based on a framework for representational flexibility that supports the development of query languages. Specifically, we consider this as a framework for data management and include data functions as a means to support data analysis. We emphasise the interaction mechanisms that support both data management and analysis. In particular, we distinguish three types of interaction: the selection of an entity of primary interest, the selection of an extent of interest, and the insertion of data functions as a means for data analysis.

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	Approaches to Design Collaboration Research
source	Automation in Construction Volume 12, Issue 6, November 2003, Pages 715-723
summary	This survey of architectural design collaboration identifies and categorizes strong research from the past ten years. It starts by describing how the research ranges in focus, scale and structure, then clarifies how different projects fit in a continuum from conceptual theory to pragmatic application. It explains how conceptual frameworks and standards enable interdisciplinary exchange by envisioning and structuring interaction. It then highlights specific interaction studies and compares methods for analyzing how media affects teamwork. The paper continues by explaining the promise of innovations such as tangible interfaces and interactive artwork, and concludes by identifying areas for further development.

summary	During the event Cultural Market Days on 23 and 24 August 2003 at Noerrebro Park in Copenhagen, visitors could also enter the marketplace from their home via the Internet, as a digital 3D model had been constructed that showed the marketplace with all its information booths and activities. This virtual marketplace functioned as an extension of the urban space, allowing you to take part in the flow of information, activities and experiences that were offered in the marketplace. And this just by a click on the Internet address: http://www.e-kvarter.dk. Furthermore at certain times of the day you could chat with people from some of the many working groups of the urban regeneration project in Noerrebro. The digital 3D model is similar to the marketplace, but it creates its own universe in the green surroundings of Noerrebro Park. And now, when the Cultural Market Days are finished and the booths and people have gone, the Electronic Marketplace still remains on the Internet, with a potential for developing a new public space for information, dialogue and cooperation between the actors of the urban regeneration project. This paper presents the results of a 3-year research project, The Electronic Neighbourhood (2000-2004). Researchers have developed and tested a digital model of the urban area and other digital tools for supporting the dialogue and cooperation between professionals and citizens in an urban regeneration project in Copenhagen. The Danish Agency for Enterprise and Housing, the Ministry for Refugees, Immigration and Integration and Copenhagen Municipality have financed the research, which is planned to be published 2004. The results can also be followed on the Internet www.e-kvarter.dk.

title	Immersion, Interaction, and Collaboration In Architectural Design Using Gaming Engines

doi	https://doi.org/10.52842/conf.caadria.2003.721
summary	"This paper investigates the role of gaming engines in the architectural design process through the introduction of features such as immersion, interaction and collaboration. While traditional 3D modelling and visualization systems such as 3D Studio MAX and form?Z offer increasingly convincing visual simulations, gaming engines are approaching the visual realism of such systems and are offering additional interactive features that are usually available only in more expensive immersive virtual reality systems . Additionally, the capability to have multiple individuals inhabit and navigate the space offers unique opportunities for collaboration as well as the investigation of human behaviour. Participants with internet access can be invited to access a shared virtual environment. Collaboration among users can be further enhanced by combining immersive navigation with peer-to-peer instant messaging and/or adding a voice channel. This paper analyzes these issues through research summary and the creation and user testing of a prototype based on a publicly available gaming engine. Through a series of assignments within an academic course, students in the school of architecture were asked to iteratively use and test this prototype for the collaborative exploration of designed environments. Students made their environments available for others to navigate in real-time and offer comments. A final design review was conducted in which critics were asked to enter the designed environment, explore it at will and interact with the student as well as others present in the same virtual space. This paper will illustrate some of the student projects and describe the immersive,"

title	Starting From The Micro A Pedagogical Approach to Designing Responsive 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. 761-770
doi	https://doi.org/10.52842/conf.caadria.2003.761
summary	The paper outlines a pedagogical approach whereby a number of technology-intensive skills can be quickly learned to a level of useful practicality through a series of discrete, yet cumulative explorations with the design goal of creating intelligently responsive architectural systems. The emerging area of responsive architecture serves as a practical means for inventing entirely new ways of developing spaces, and the designing and building environments that address dynamic, flexible and constantly changing needs. Responsive architecture is defined here as spaces and objects that can physically re-configure themselves to meet changing needs. The central issues explored are human and environmental interaction and behaviors, embedded computational infrastructures, kinetic and mechanical systems and physical control mechanisms. Being both multidisciplinary and technology-intensive in nature, architects need to be equipped with at least a base foundational knowledge in a number of domains in order to be able to develop the skills necessary to explore, conceive, and design such systems. The teaching methods were carried out with a group of undergraduate design students who had no previous experience in mechanical engineering, electronics, programming, or kinetic design with the goal of creating a responsive kinetic system that can demonstrate physical interactive behaviors on an applicable architectural scale. We found the approach to be extremely successful in terms of psychologically demystifying

title	Changing the Metaphor: Cyberspace as a Place
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. 19-28
summary	Cyberspace is quickly becoming an alternative ‘place’ for everyday economic, cultural, and other human activities. It ought, therefore, to be designed according to the principles, theories, experiences, and practices that have been guiding physical placemaking for thousands of years, rather than the woefully inadequate metaphor of the printed page. 3D Cyber-places must embrace the essential characteristics that make a ‘place’ in physical space, while at the same time take advantage of the opportunities offered by Cyberspace. By looking at physical architecture as a case study and metaphor for organizing space into meaningful places, this paper discusses the possibility of organizing Cyberspace into spatial settings that, like physical places, afford social interaction and embody cultural values.

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	Virtual environments in architecture and planning design: 4 possible approaches
source	International Journal of Design Computing
summary	Advancements in information retrieval (IR), local and wide area networks (LAN, WAN) and the Internet, human-computer interaction (HCI), and virtual reality (VR) technologies have enabled the emergence and availability of affordable real-time computer data visualisation and manipulation systems that can be deployed and interfaced to most Computer Aided Design (CAD) software systems. However, the rapid advancement and adoption of information visualisation in different areas is currently challenging VR system designers to formulate and deploy strategies and tools to effectively visualise, navigate and effectively communicate various types of information within a virtual environment (VE). A further problem relates to the fact that even within a single area or application the requirements are still diverse to the extent that different approaches and technologies still need to be employed before a satisfactory solution is reached. This paper presents four possible approaches in identifying and designing effective VR systems for architecture and planning design to allow the user to effectively communicate and share their experiences and ideas in a collaborative manner. It is also proposed that VEs should look beyond plain representations and reproductions of the real world environments that they portray and bear higher interpretation and expression values. The value of eliciting structuring and interfacing information and knowledge to a VE is also highlighted, as is the need for efficient database systems and CAD systems capable of exchanging information and data with VEs. Current efforts in prolonging the lifetime of VEs are being examined through four case studies that highlight the ever-escalating requirements that currently face VR researchers.

summary	Recently, more and more researchers dedicated in the development of human computer interaction for CAD systems, such as gestural input of three dimensional coordinates (Lee, Hu, and Selker, 2005), flexible manipulation of NURBS objects (Cohen, Markosian, Zeleznik, Hughes, and Barzel, 1999; Emmerik, 1990), and the creation of force feedback (Wu, 2003). These research results indicated that the more intuitive control the device can provide in modeling process, the more creative solutions can be generated (Lee, Hu, and Selker, 2005; Schweikardt and Gross, 2000; Wu, 2003).

summary	In this paper we discuss designing abilities, such as creativity and learning, as abilities that emerge though interaction in cooperative human-machine networks. We concentrate in a design system that can exhibit and support creative behaviour using knowledge learnt through distributed human-machine interaction. In this context, conflict resolution and coordination is a main issue, as well as a main indicator for the creative and adaptive ability of the design system. More specifically, we are going to present a model of coordination developed using learning control and multi-agent systems methodologies and techniques. A prototype system is tested in a virtual collaborative design assignment for simple location and three-dimensional configuration problems.

title	DEVELOPING A VIRTUAL REALITY-BASED METHODOLOGY FOR PEOPLE WITH DEMENTIA: A FEASIBILITY STUDY.
source	Journal of CyberPsychology and Behavior, Vol6, Number6, 2003.
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.

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

summary	Design agents are rational agents that monitor and modify elements of a designed environment. Special characteristics of design agents include the ability to reason about patterns and concepts, and the ability to act autonomously in modifying or changing the design to achieve their own goals. 3D Virtual Worlds are multi-user distributed systems that provide a designed environment and a closed world environment for studying design agents in a multiagent system. We present a model for a design agent reasoning process and a model for constructing a memory of the agent’s knowledge and interaction with a virtual world. The reasoning process includes sensation, perception, conception, hypothesizing, and planning a sequence of actions. Each agent has a constructed memory: a dynamic and changing view of the designed world that is determined by the agents sense data and reasoning. The agents construct and maintain a representation of the relevant objects in the world using a Function- Behavior-Structure formalism in order to reason about the intended and actual functions of the designed objects in the world. We have implemented this agent model by extending the Active Worlds platform so that each object in the 3D world can have agency. We illustrate the model with a door agent and a multi-agent room that reason about the use of the 3D world.
