summary	In this paper we report on ongoing research in which the implications of urban scale pervasive computing (always and everywhere present) are investigated for urban life and urban design in the heritage environment of the city of Bath. We explore a theoretical framework for understanding and designing pervasive systems as an integral part of the urban landscape. We develop a framework based on Hillier's Space Syntax theories and Kostakos' PSP framework which encompasses the analysis of space and spatial patterns, alongside the consideration of personal, social and public interaction spaces to capture the complex relationship between pervasive systems, urban space in general and the impact of the deployment of pervasive systems on people's relationships to heritage and to each other. We describe these methodological issues in detail before giving examples from early studies of the types of result we are beginning to find.

title	Critical Environmentalism and the Practice of Re-Construction
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	This research focuses on the implications and applications of “critical environmentalism” as a quintessential epistemological framework for urban interventions while implementing digital applications that foster collective, round-table approaches to design. Essentially centering the environment (Umwelt) as an encompassing and interconnecting catalyst between multiple disciplines, philosophies, and modes of inquiry and technologies, the framework reciprocally fosters individual and critical identities associated with particular places, belief systems, and their participants as a primary concern. Critical environmentalism promotes a comprehensive, reciprocally unifying epistemological framework that can significantly inform architectural interventions and the tethered use of its technologies in order to foster increased vitality and a certain coinvested attention to the complexities of the greater domain. Grounding the theory in pedagogical practice, this paper documents an approach to urban design and architectural education, implemented as a case-study and design scenario, where divergent perspectives amalgamate into emergent urban configurations, critically rooted in the conditional partialities of place. Digital technologies are incorporated along with analogical methods as tools to integrate multiple perspectives into a single, working plane. Engaging the above framework, the approach fosters a critical (re)construction and on-going, co-vested regeneration of community and the context of place while attempting to dialogically converge multiple urban conditions and modes-of-thought through the co-application of various digital technologies. Critically understanding complex urban situations involves dialogically analyzing, mapping, and modeling a discursive, categorical structure through a common goal and rationale that seeks dialectic synthesis between divergent constructions while forming mutual, catalyzing impetuses between varying facets. In essence, the integration of varying technologies in conjunction, connected to real world scenarios and a guiding epistemic framework cultivates effective cross-pollination of ideas and modes through communicative and participatory interaction. As such it also provides greater ease in crosschecking between a multitude of divergent modes playing upon urban design and community development. Since current digital technologies aid in data collection and the synthesis of information, varying factors can be more easily and collectively identified, analyzed, and then simultaneously used in subsequent design configurations. It inherently fosters the not fully realized potential to collectively overlay or montage complex patterns and thoughts seamlessly and to thus subsequently merge a multitude of corresponding design configurations simultaneously within an ongoing, usable database. As a result, the pedagogical process reveals richly textured sociocultural fabrics and thus produces distinct amplifications in complexity and attentive management of diverse issues, while also generating significant narratives and themes for fostering creative and integrative solutions. As a model for urban community and social development, critical environmentalism is further supported the integrative use of digital technologies as an effective means and management for essential, communicative interchange of knowledge and thus rapprochement between divergent modes-of-thought, promoting critical, productive interaction with others in the (co)constructive processes of our life-space.

title	Collaborative Architectural Design as a reflective Conversation: an agent facilitated system to support collaborative conceptual design
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	In this paper, definitions of collaborative design are discussed and understood in terms of a designer’s cognitive collaborations to explore his/her experiential memory for remote idea associations. Based on Schon’s reflective practice theory, Valkenburg and Dorst’s (1998) description of collaborative team designing is adopted as a model for a proposed design conversation system. The design conversation system is aimed at triggering the experiential memory of the designer by associating significant ideas from different design domains to provide different perspectives of a design situation. The paper describes a proposed framework for the design conversation system incorporating computational agents in a blackboard architecture environment.

title	A Framework of Haptic Design Parameters for Architects: Sensory Paradox Between Content and Representation
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. 685-700.
summary	Architects‚Äîlike other designers‚Äîtend to think, know and work in a visual way. In design research, this way of knowing and working is highly valued as paramount to design expertise (Cross 1982, 2006). In case of architecture, however, it is not only a particular strength, but may as well be regarded as a serious weakness. The absence of non-visual features in traditional architectural spatial representations indicates how these are disregarded as important elements in conceiving space (Dischinger 2006). This bias towards vision, and the suppression of other senses‚Äîin the way architecture is conceived, taught and critiqued‚Äîresults in a disappearance of sensory qualities (Pallasmaa 2005). Nevertheless, if architects design with more attention to non visual senses, they are able to contribute to more inclusive environments. Indeed if an environment offers a range of sensory triggers, people with different sensory capacities are able to navigate and enjoy it. Rather than implementing as many sensory triggers as possible, the intention is to make buildings and spaces accessible and enjoyable for more people, in line with the objective of inclusive design (Clarkson et al. 2007), also called Design for All or Universal Design (Ostroff 2001). Within this overall objective, the aim of our study is to develop haptic design parameters that support architects during design in paying more attention to the role of haptics, i.e. the sense of touch, in the built environment by informing them about the haptic implications of their design decisions. In the context of our study, haptic design parameters are defined as variables that can be decided upon by designers throughout the design process, and the value of which determines the haptic characteristics of the resulting design. These characteristics are based on the expertise of people who are congenitally blind, as they are more attentive to non visual information, and of professional caregivers working with them. The parameters do not intend to be prescriptive, nor to impose a particular method. Instead they seek to facilitate a more inclusive design attitude by informing designers and helping them to think differently. As the insights from the empirical studies with people born blind and caregivers have been reported elsewhere (Authors 2010), this paper starts by outlining the haptic design parameters resulting from them. Following the classification of haptics into active, dynamic and passive touch, the built environment unfolds into surfaces that can act as ‚Äúmovement‚Äù, ‚Äúguiding‚Äù and/or ‚Äúrest‚Äù plane. Furthermore design techniques are suggested to check the haptic qualities during the design process. Subsequently, the paper reports on a focus group interview/workshop with professional architects to assess the usability of the haptic design parameters for design practice. The architects were then asked to try out the parameters in the context of a concrete design project. The reactions suggest that the participating architects immediately picked up the underlying idea of the parameters, and recognized their relevance in relation to the design project at stake, but that their representation confronts us with a sensory paradox: although the parameters question the impact of the visual in architectural design, they are meant to be used by designers, who are used to think, know and work in a visual way.

title	An Internet Survey for an Activity-Based Model - An urban transportation analysis integrated in a G.I.S. environment
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Progress in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN-10: 90-386-1756-9, ISBN-13: 978-90-386-1756-5, p. 3-17
summary	The current research deals with the development of an Activity-Based Multi Agent System fully implemented in a G.I.S. framework and applied to the case study of the historical centre of Pisa. The objective is to create a simulation tool for Pisa population transfers in order to verify how transport demand varies because of interventions on traffic plan (e.g. creating urban areas subject to a toll access for vehicles), or on public transport lines, or on new activities location (e.g. supermarkets, public services etc.). Three different parts of the System have been simultaneously carried out: the first concerns a population sample survey, the second deals with geographical data structuring and the last one, still in elaboration progress, tests the model reliability to estract and implement behavioural rules. The results obtained till now show how the Database itself, containing temporal data about agents activities (extracted by the population sample questionnaire) and urban services the city offers, already represents an important instrument to support decision making process.

title	The potential of Virtual Environments as contexts for Communication
doi	https://doi.org/10.52842/conf.ecaade.2006.750
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 750-753
summary	This paper documents a study done considering Virtual Reality (VR) as a spatial representational context which supports communication. It aims to identify whether VR could be considered as a communication medium, a tool that could be used for the successful transmission of information and messages, as well as the future form, content and use of it. That is, how does communication occur in a Virtual Environment (VE), by taking into account its visual properties and spatial parameters and under which conditions communication messages are conducted via VR systems, deriving from the one part (sender) and concluding to the other (receiver). The methods selected for this study involve observation and use of questionnaires at the end of each session. An already existing Internet-based online multi-user virtual environment has been chosen as the context where this survey will be carried out, that is the site Active Worlds, http://www.activeworlds.com, which can be accessed very easy to any computer user, in a desktop form. Firstly, we investigated the time needed, depending on the complexity per case, for a user of the VR application to get acquainted with the system. We were interested to know if the meaning that we would like to communicate had either remained the same through all the time of the experience or had been “modified” in a certain way and if so, for what reason. Another issue that was examined was the way in which the spatial context in a specific VE affects the way communication occurs. The framework of the application may influence the way the person receives a message, for example by making assumptions and references that he would not have made in a different environment- outside VR. After the end of the experience, the user was invited to describe his/ her impressions, with the communication factor being stressed, that is to mean if and at what extent VR can be characterized as a communication medium, as it is mentioned above, even for limited information and messages in general.

title	Energy conscious automated design of building façades using genetic algorithms
doi	https://doi.org/10.52842/conf.ecaade.2006.898
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 898-902
summary	Various European Directives have been issued concerning the energy efficiency of the buildings. The target is the achievement of a near optimum energy efficient environment while at the same time satisfying occupant needs throughout the year within an integrated “holistic” or “whole building” framework. A variety of different antagonistic parameters should be balanced such as window size and glazing transmittance or daylighting and shading and in most cases this requires an examination of various scenarios. Thus the design of building envelopes should address a careful balance between internal requirements and loads, the materials and properties of the façade and the external environment. Nowadays, the available tools for façade design-in terms of building’s energy efficiency- are inappropriate for interactive or creative use. In this paper we examine the development of a genetic algorithm which is capable to optimise the opening areas, glazing properties and shading configurations –on the basis of minimum energy consumption- and then to design automatically simplistic alternative scenarios of the building façade.

title	Taller Virtual de Las Américas: Análisis, Síntesis y Propuesta de Desarrollo en Ambientes Multiusuarios Interactivos [America’s Virtual studio: Analysis, Synthesis and Proposal for develop an interactive multi-user environment]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 105-109
summary	As the title suggests, this paper makes an attempt to provide a factual analysis and synthesis of the activities that the Tex-Mex Virtual Design Studio, and later the Las Americas Virtual Design Studio, have been implementing since September of 1996, The objective of this attempt is to provide a framework for the formulation of a new conceptual and instrumental profile for future implementations of our virtual design studios. With such a purpose the paper outlines the importance of virtual design studios in the framework of opening design education to distance education methodologies and argues in favor of their further utilization for addressing issues of globalization in architecture and design education. This argument is followed by a quick description of current practices within the Las Americas Virtual Design Studio and sets the stage for a detailed description of how multi-user interactive environments may further support interaction within virtual design studios.

title	Light and Form in Design – A Computational Approach
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 254-257
summary	Shape perception is strongly influenced by the reciprocal relation between light and form. Computational applications can increase the number of design alternatives taking into account possible variations in the relation between light and form. The aim of this study is to discuss a pedagogical experience carried out with 5th semester architectural students, based on a series of exercises prior to the term project. The exercises were concerned with the relation between light and form from an aesthetical point of view and should be understood as examples for the use of computers as tools to creatively accelerate the process of design and learning. The paper is divided in five parts. The first one describes the conceptual background for the exercises, a descriptive method for the identification of light effects in architectural objects based on ideas of shape emergence. The exercises’ methodology is explained in the second part, referring to the use of computational applications in 3-dimensional modeling, material and light simulation. The methodology includes different phases: –creation of bi-dimensional compositions according to symmetry operations; –creation of a minimal living space assigning functions to spaces originated from the former composition; –analysis of the impact of light on the form and spaces created; –alteration of form and materials creating new light effects considering the functions related to the spaces. The exercises alternate work in computational environment in two and three dimensions with the use of mockups, lamps and photography. In the third part the results –student’s design steps– are described. In the fourth part the results are analyzed and some conclusions are outlined in the fifth and last part. The use of emergent forms combined with computational tools has proved to be an effective way to achieve an accelerated understanding of the impact of light on forms as demonstrated by the evolution of the students work during the term and by their final results concerning the term project.

title	Hybrid[s] : new pedagogical applications for designing our evolving spatial environment
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 131-136
summary	The continual emergence of new informational and technological systems has impacted our cultural landscape. As society continues to evolve, we are becoming more connected to virtual systems that impact our spatial environment. The awareness and understanding of these invisible forces requires new curricular pedagogies in architectural education. This paper will document an ongoing course that was developed to research new methodologies for working with haptic environments and informational systems. Utilizing a high performance-computing center, students in the class are developing new adaptive intelligent spatial systems that engage a multiplicity of scales. They researched environments for PDA’s (Personal Data Assistance), I-Pods, cellular phones, GPS (Guidance Positioning Systems) and a new immersive virtual dome environment. The goal of the class was to reevaluate how architectural practice in the future will encompass a more holistic approach to both physical and virtual spatial development.

title	Immersive Drafted Virtual Reality a new approach for ideation within virtual reality
doi	https://doi.org/10.52842/conf.acadia.2006.304
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 304-316
summary	There is a void between design and computer in ideation. Traditional tools like sketching are more appropriate for conceptual design since they can sustain abstraction, ambiguity, and inaccuracy—essentials at the beginning of the design process. Actual graphical user interface approaches, as well as hardware devices, constrain creative thinking. Computer representations and virtual reality are now used for presentation and validation rather than for design. Most virtual reality tools are seen as passive rather than active instruments in this process of ideation. Moreover, virtual reality techniques come from other disciplines and are applied to design without considering the design process itself and the skills designers already possess.This paper proposes and evaluates a new approach for the conceptual design of spaces within virtual reality. Starting from the non-immersive technique we developed before, where the user was able to be inside a 3D modeled space through real sketches, this technique goes one step further, allowing the designer to sketch the space from the inside all in real-time. Using an interactive pen display for sketching and an immersive projective spherical display, designers and colleagues are able to propose and make design decisions from inside the project. The capabilities of the computer to display the virtual environment are, therefore, mixed with the designer’s skills in sketching and understanding the space.

source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 884-889
summary	Part of an EU funded project to develop a “VIrtual campus for virtual space design Provided for European Architects (VIPA)” was the implementation of a practical run at the Vienna University of Technology. Therein we attempted to evaluate some of the concepts and technologies which were intended for the e-learning platform. After briefly introducing the didactical background, this paper concentrates on the technological setup accompanying the course. Especially the use of Croquet as an immersive three-dimensional environment to teach generative design is highlighted; its strengths and weaknesses in supporting our envisioned didactical concept are analysed. The practical run and its evaluation by the participating students are described, as well as some of the student work performed during and after the course. Concluding remarks elaborating on problems encountered in the software setup and in our didactical concept, followed by the description of future work to amend the above mentioned pitfalls, will mark the end.

summary	This paper focuses on using oversized display for supporting design communication process between designers and clients. The interactive behaviors are analyzed and testified with a prototype developed in this research. Based on interviews with designers and clients, focus of the communication process in this research is onto developing an immersive environment for exchanging and negotiating the design artifacts. Several immersive virtual environment as well as visualization method (display) is reviewed. Furthermore, three over-sized display projects (ShadowLight, CaveUT and Blue-c) with immersive perception at full-scale or near full-scale design artifacts are studied as the inspiration of this research. Designers identify what kinds of influence they had on the design of client's interior space and to what extent they are aware that they can design and influence their perception. An over-sized display environment with direct manipulation interface is developed for evaluation platform.

summary	This paper describes the integration of machine intelligence into an immersive architectural sculpture that interacts dynamically with users and the environment. The system is conceived to function as an architectural envelope that might transfer air using a distributed array of components. The sculpture includes a large array of interconnected miniature structural and kinetic elements, each with local sensing, actuation, and machine intelligence. We demonstrate a model in which these autonomous, interconnected agents develop cooperative behaviour to maximize airflow. Agents have access to sensory data about their local environment and ‘learn’ to move air through the working of a genetic algorithm. Introducing distributed and responsive machine intelligence builds on work done on evolving embodied intelligence (Floreano et al. 2004) and architectural ‘geotextile’ sculptures by Philip Beesley and collaborators (Beesley et al. 1996-2006). The paper contributes to the general field of interactive art by demonstrating an application of machine intelligence as a design method. The objective is the development of coherent distributed kinetic building envelopes with environmental control functions. A cultural context is included, discussing dynamic paradigms in responsive architecture.

summary	In this paper we describe a SketchUp VR system in which we create a hybrid two-dimensional / three-dimensional immersive architectural design system. This system combines a tablet PC, an optically tracked room, a display wall, a Space Traveler motion controller, and stereographic eyewear to allow immersive conceptual design and walkthrough using a version of SketchUp that has been enhanced with Ruby plug-ins. The tablet PC provides a ”sketchpad” type of user interface for SketchUp, while the tracked space and display wall enable the designer simultaneously to design at full (or any other) scale in an immersive (VR) environment.

summary	This paper illustrates the methodology, technological solutions and interaction metaphors chosen for the development of a 3D immersive Virtual exhibition that aims at enriching the visit of an important part of the historical cultural heritage of the city of Trento, in Italy. The goal of this work, supported by the local authority for Cultural Heritage, was to implement a user friendly virtual environment, which could show to the visitors the significance of the archeological findings of the ancient Roman town of Tridentum, despite the peculiarity of the site’s premises, located below a square among a theatre foundations. Outcomes of the research work are a high-quality and scientifically correct reconstruction of the Roman town in various historical eras, thanks to fruitful interaction with archeologists, and the development of an ad-hoc user-friendly immersive virtual environment implementing a customized interaction metaphor for the fruition of the virtual reconstruction. The developed interface allows users speaking different languages to share simultaneously the experience of virtual tours across time using a joystick. The whole environment has been developed to become a permanent virtual exhibition in the premises of the archeological site.

title	Branches and Bifurcations - Building a framework for modeling with isosurfaces in Generative Components
doi	https://doi.org/10.52842/conf.ecaade.2006.868
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 868-873
summary	An isosurface is a three-dimensional representation of a constant value of a field function within a given volume. They are normally used in computer graphics to visualize data in fluid dynamics, medical imaging, geophysics, and meteorology. The advantage of isosurfaces is that they can represent all sorts of topologies. That makes them a perfect tool for modeling, branching, forking, and bifurcating objects with smooth transitions. As they work of a field function, the surface is implicit, the polygonization an approximation. This is a good base for coupling performance with precision. The task was to define a set of handles to change and model an isosurface. It had to happen through the modeling of the field function in a way that is rather intuitive but without giving up the precision one is used to have from standard NURBS/BREP modeling. The paper shows how a modeling framework for isosurfaces is implemented as a plug-in for Bentley Systems Generative Components allowing an intuitive way of exploring design variations. The implementation is illustrated with a proof of concept showing a sketch design.

summary	The diversity of representations and the complexity of capturing and communicating the design process and its rationale present a challenge to architects. This paper proposes a multimodal virtual reality environment (MVE) aimed at utilizing the inherent advantages of distinct media, as opposed to a stand-alone virtual reality environment. Virtual reality is seen here as one of the tools in the larger milieu of interactive multimedia tools available to architects. The theoretical framework underlying its development explores the role of digital tools in the design process, their adaptability to existing workflow and issues of representation and perception, especially how design ideas are represented, evaluated and manipulated in the mind. The development of MVE followed a cycle of design, usability studies by a focus group and redesign.

summary	Context awareness is important for human senses of places as well as human computer interaction. The aim of this research paper is focusing on controlling the user's privacy in a smart space which is adaptive to different users for enhancing the user's awareness in his diary life. In Environmental Psychology, the definition of privacy is that an individual has the control of deciding what information of himself is released to others, and under how he interact with others. (Westin 1970) And privacy is categorized as the linguistic privacy and visual privacy. (Sundstorm 1986). Solutions for privacy control: Plan Layout, Vision Boundary, Access Control and Architecture Metaphor - the transmission of information is not ascertainable for every single user. Although information are shown in public, but information is implied by cues and symbols. Only a certain user or a group of users have access to the full context of information. The methodology is to form an analytic framework to study the relationship between information, user and activities by using the computational supports derived from KitchenSense, ConceptNet, Python, 3d Studio Max and Flash; and to record patterns built up by users' behaviour and actions. Furthermore, the scenario-based simulation can envision the real world conditions by adding interfaces for enhancing user awareness.

title	Bidirectional Interoperability Between CAD and Energy Performance Simulation Through Virtual Model System Framework
doi	https://doi.org/10.52842/conf.acadia.2006.232

summary	The paper describes a novel approach involving interoperability, data modeling technology, and application of the building information model (BIM) focused on sustainable architecture. They share relationships and multiple experiences that have existed for years but have never have been proven. This interoperability of building performance simulation maps building information and parametric models with energy simulation models, establishing a seamless link between Computer Aided Design (CAD) and energy performance simulation software. During the last four decades, building designers have utilized information and communication technologies to create environmental representations to communicate spatial concepts or designs and to enhance spaces. Most architectural firms still rely on hand labor, drafted drawings, construction documents, specifications, schedules and work plans in traditional means. 3D modeling has been used primarily as a rendering tool, not as the actual representation of the project.With this innovative digitally exchange technology, architects and building designers can visually analyze dynamic building energy performance in response to changes of climate and building parameters. This software interoperability provides full data exchange bidirectional capabilities, which significantly reduces time and effort in energy simulation and data regeneration. Data mapping and exchange are key requirements for building more powerful energy simulations. An effective data model is the bidirectional nucleus of a well-designed relational database, critical in making good choices in selecting design parameters and in gaining and expanding a comprehensive understanding of existing data flows throughout the simulation process, making data systems for simulation more powerful, which has never been done before. Despite the variety of energy simulation applications in the lifecycle of building design and construction projects, there is a need for a system of data integration to allow seamless sharing and bidirectional reuse of data.
