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 A framework towards designing responsive public information systems
source Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 767-782
summary "Evolving effective responsive systems, and creating a credible interface between the work and the user, requires an awareness of many different types of user, contexts and functions as well as the phenomenological aspects of social and environmental conditions." (Bullivant, 2006). Responsive design and interactive architecture operates at the intersection of Architecture, Arts, Technology, Media Arts, HCI and Interaction Design in a physical context suggesting ways in which the existing physical environments can be augmented and extended adding a greater level of depth, meaning and engagement with the world around us. Through a series of case studies, this paper explores a number of principles which may be applied to the design of responsive environments of which public information systems form part. Divided into three main sections, the paper first explains how responsive environments have addressed the application of public information systems, secondly, through a series of case studies, precedents are highlighted which lead to development of principles for developing designs for responsive environments. The third section discusses and elaborates on these principles which have been developed based upon our own interpretations and grouping of precedents and approaches towards interaction design. This paper contributes towards the field of responsive environments and interactive architecture through an analysis of case studies to infer a framework from which responsive environments may be created and developed.

title A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title Empathy over distance: Wearables as tools for augmenting Remote Emotional Connection
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 66-69
summary Mainstream communication modes emphasise network speed, connection access, resolution, portability, and aesthetic design as primary to the success of their products. Within this vision a three by four centimetre screen and high resolution display are deemed adequate to emulate the intensities and complexities of face-to-face connection with loved ones. They allow us to ‘be there with you’ from wherever we might be. Yet interpersonal communication is a massively complex phenomenon. It involves a plethora of micro-activities which occur at a physical, physiological, and psychological level allowing us to recognise at a cellular scale intention, motive and emotional authenticity. Our conscious and non-conscious involvement in spatially collocated communication is substantial due to these myriad channels of real-time bi-directional information transfer. While contemporary communications technologies have the capacity to mediate our relationships, they fall short of encouraging the richness of spatially co-present interaction. The research discussed in this paper investigates the potential expansion of remote connection when electronically enhanced apparel is incorporated into the communications mix. Rather than pursuing the manifold functionalities of traditional communications media the garments discussed focus solely on the goal of enhancing empathy between physically distant individuals. This paper reports on the development and testing of a range of garments that conduct presence information between remotely located people. The garments sense, process, transmit and receive the heartbeat wavelength (ECG). They are enabled with ECG sensors, signal processing equipment, small vibration motors, and radio transceivers which allow users to ‘feel’ the heartbeat of a remote friend/lover/relative as vibration through their garment. The prototypes aim to enrich the remote communications experience through reintroducing an embodied, tactile dimension that is present in face-to-face communication. A range of user testing trials will be discussed which have been undertaken to assess the impact of the garments at a conscious and a non-conscious level. Conscious experiences were gauged through qualitative testing, by way of interviews and unsolicited written reactions, which have provided a range of engaging emotional responses. Non-conscious physiological reactions were assessed by recording ECG throughout user-testing periods. This data has been processed using HRV (heart rate variability) analysis software, running on MatLab. Preliminary results suggest that users have strong conscious and non-conscious reactions to the experience of wearing the prototype garments. The paper will describe the data processing techniques and findings of the user testing trials. The development of biosignal sensing garments has raised a range of issues including: innovative potentials for embedded peripheral awareness media; the expansion of the classical body to incorporate remotely sensed information; the issue of data semantics and the development of intensely personal non-verbal languages; and the issue of corporeal privacy when one’s biological information is exposed for potential download. They also bring into question how our bodily experiences might change when we incorporate remote sensory systems.

title Properly Equip Planners, Instead of Just Manning Equipment - A first step in a user-oriented PSS development approach as support for the integration of land use and transport planning
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. 35-50
summary There is a growing need for planning support in planning practice, especially in land use and transport integration. Recent studies have shown that instruments that provide such are seldom implemented. Building on recommendations of those studies, this paper explores how to develop a planning support system (PSS) for this specific field of planning and shows some preliminary results of the first steps towards such a PSS. An qualitative assessment on the strengths and weaknesses of two recently developed instruments that share this goal; the VPR and the SDS+STE. Due to time constraints, the focus is on the background and framework of the study.

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.

summary Existing land-use allocation methods assume that the suitability of a spatial distribution of land-uses can be measured as the sum of suitability scores across parcels. Although this may be plausible for some land-uses, facilities such as retailing, schools, medical services, etc., intend to serve the needs of a local population and should be evaluated at the level of a facility network, instead. The purpose of the present paper is to develop a method that combines a suitable heuristic for facility-location planning with an existing mechanism for land-use allocation, to solve this shortcoming of existing models. In specific, the proposed method combines the interchange heuristic for locating facilities and a swapping heuristic for area-type land-use allocation in a multi-agent framework. A case study shows that the method generates plausible land-use plans in reasonable computation time.

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 An Analysis of the Applications of Rapid Prototyping in Architecture
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 Rapid prototyping (RP) techniques are widely used within the design/manufacturing industry and are well established in manufacturing industry. These digital techniques offer quick and accurate prototypes with relatively low cost when we require exact likeness to a particular scale and detail. 3D modeling of buildings on CAD-systems in the AEC sector is now becoming more popular and becoming widely used practice as the higher efficiency of working with computers is being recognized. However the building of scaled physical representations is still performed manually, which generally requires a high amount of time. Complex post-modernist building forms are more faithfully and easily represented in a solid visualization form, than they could be using traditional model making methods. Using RP within the engineering community has given the users the possibility to communicate and visualize designs with greater ease with the clients and capture any error within the CAD design at an early stage of the project or product lifecycle. In this paper, the application of RP in architecture is reviewed and the possibilities of modeling architectural models are explored. A methodology of developing rapid prototypes with 3D CAD models using methods of solid freeform manufacturing in particular Fused Deposition Modeling (FDM) is presented and compared against traditional model making methods. An economical analysis is presented and discussed using a case study and the potential of applying RP techniques to architectural models is discussed.

summary Present study primarily aims to outline a theoretical framework for developing a computational model towards the creative use of architectural precedents in architectural design education. It departs from a short summary of the critical/formalist approach as the model that we adopt for the studio education, and goes on with a discussion on paradigms or precedents as the containers of knowledge and as the primary focus of the studio model as important elements of architectural design education. Prior to conclusion the study sets three important problem areas concerning the model, from the computational point of view, and investigates them while trying to outline a framework towards a computational model. As a conclusion it proposes two main areas that we can utilize computers for the creative use of architectural precedents in architectural design education, and discusses a possible studio implementation of the proposed framework as the next stage of the study.

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.

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 It is widely held that sometime around 2006, the World Wide Web as we knew it mutated into Web 2.0. This colloquial label signaled a shift from an Internet designed for us to an Internet designed by us. Nowhere was this more explicitly stated than in Time Magazine’s 2006 Person of the Year selection: You. More than a decade later, Internet browsers have evolved into ubiquitous interfaces accessible from mobile devices, tablet computers, public kiosks, workstations, laptops, etc. It would, therefore, not be an overstatement to say that the browser is the most widespread content canvas in the world. Designers frequently use web browsers for their ability to exhibit and organize content. They are the sites for portfolios, announcements, magazines, and at times, discussions. But despite its flexibility and rich infrastructure, rarely is the browser used to generate design elements. Thanks to advanced web development languages like JavaScript and open-source code libraries, such as p5.JS, Matter.JS, and Three.JS, browsers now support interactive and spatial content. Typically, these tools are used to generate gimmicks or visual effects, such as the parallax illusion or the infinite scroll. But if we perceive the browser as a timebased picture plane, we can immediately recognize its architectonic potential. This paper puts forth a method for engaging the creative potential of web-based media and Internet browsers. Through example projects, I argue that the Internet browser is a highly complex spatial plane that warrants more architectural analysis and experimentation.

summary Provided with a strict set of rules a computer program can perform the role of a simple designer. Taking advantage of a computer’s processing power, it can also provide an unlimited number of variations in the form while following a given set of constraints. This paper delineates a model for interrelating a rule-based system based on purely architectural considerations with non-deterministic computational procedures in order to provide controlled variations and constrained unpredictability. The experimental model consists of a verisimilar architectural problem, the design of a residential tower with a strict program of 200 units of different types in a given site. Following the interpretation of the program, a set of rules is defined by considering architectural concerns such as lighting, dimensions, circulations, etc. These rules are then encoded in a program that generates form in an unsupervised manner by means of a stochastic search algorithm. Once the program generates a design it’s evaluated, and the parameters on the constraints are adjusted in order to produce a new design. This paper presents a description of the architectural problem and of the rule building process, images and descriptions of three different towers produced, and the code for the stochastic-search algorithm used for generating the form. The succesful evolution of the experiments show how in a computation-oriented design process the interpretation of the problem and the rule setting process play a major role in the production of meaningful form, outlining the shifting role of human designers from form-makers to rule-builders in a computation-oriented design endeavour.

summary Shape grammars are the algorithmic systems used to analyze existing designs or create new ones. In spite of using text or symbols to express abstract representations, shape grammars aid to create novel designs through computational effort with shapes and rules. Many probabilities of rule selections and applications of these rules may generate emergent design solutions or create new design objectives. This paper aims to present the characteristics, shape grammar rules and historical background of geometrical ornaments in Islamic culture and to point out the possibilities of mathematics of symmetry. The knowledge presented in this paper can be used to generate new depictions and to gain new application areas like typography, wallpaper, landscape, façade design, tiling, jewelry, and textile designs. Even, these types of shape grammar studies can be used to open a novel approach as in Jean Nouvel’s “Arab World Institute” in Paris. The role of shape grammar analysis of geometrical Islamic ornaments explained in this paper is to increase the efficiency of architectural design education by facilitating the formal understanding of historical patterns. Novel use of shape grammars in education can enrich the designer’s ability to generate original designs. In this paper variants of Islamic ornaments are created with a CAAD program. A selected geometrical bezeme (ornament) from Islamic ornamental design is generated by encoding with a computer programming language. According to the generated bezeme, interaction scenario is as follows: Computer has the main control over grammar application. Only, some of the rules can be selected by the user. Varieties of this ornament are generated randomly through their line weight, line colors, filling types and filling colors. The shape grammar rules outlined in this paper are simple, but the resulting figures can be very inspiring. Furthermore, the endless potential for future design innovations is unlimited.

title Bidirectional Interoperability Between CAD and Energy Performance Simulation Through Virtual Model System Framework
doi https://doi.org/10.52842/conf.acadia.2006.232
source Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 232-250
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.

summary The study describes some of the aspects tackled within a current Ph.D. research where architectural applications of constructive, structural and organization processes existing in biological systems are considered. The present information processing capacity of computers and the specific software development have allowed creating a bridge between two holistic nature disciplines: architecture and biology. The crossover between those disciplines entails a methodological paradigm change towards a new one based on the dynamical aspects of forms and compositions. Recent studies about artificial-natural intelligence (Hawkins, 2004) and developmental-evolutionary biology (Maturana, 2004) have added fundamental knowledge about the role of the analogy in the creative process and the relationship between forms and functions. The dimensions and restrictions of the Evo-Devo concepts are analyzed, developed and tested by software that combines parametric geometries, L-systems (Lindenmayer, 1990), shape-grammars (Stiny and Gips, 1971) and evolutionary algorithms (Holland, 1975) as a way of testing new architectural solutions within computable environments. It is pondered Lamarck´s (1744-1829) and Weismann (1834-1914) theoretical approaches to evolution where can be found significant opposing views. Lamarck´s theory assumes that an individual effort towards a specific evolutionary goal can cause change to descendents. On the other hand, Weismann defended that the germ cells are not affected by anything the body learns or any ability it acquires during its life, and cannot pass this information on to the next generation; this is called the Weismann barrier. Lamarck’s widely rejected theory has recently found a new place in artificial and natural intelligence researches as a valid explanation to some aspects of the human knowledge evolution phenomena, that is, the deliberate change of paradigms in the intentional research of solutions. As well as the analogy between genetics and architecture (Estévez and Shu, 2000) is useful in order to understand and program emergent complexity phenomena (Hopfield, 1982) for architectural solutions, also the consideration of architecture as a product of a human extended phenotype can help us to understand better its cultural dimension.
