title Beyond the low-hanging fruit: Information technology in architectural design past, present and future
source W. Mitchell and J. Fernandez (eds), ACSA Technology Conference, MIT Press, Cambridge MA
summary Today's commercial CAD software is the product of years of research that began in the 1960's and 1970's. These applications have found widespread use in the architectural marketplace; nevertheless they represent only the first fruits of research in computer aided design. New developments based on research in human-computer interaction (HCI), computer-supported collaborative work (CSCW), and virtual reality (VR) will result in a next generation of tools for architectural design. Although preliminary applications to design have been demonstrated in each of these areas, excellent opportunities remain to exploit new technologies and insights in service of better design software. In this paper we briefly examine each of these areas using examples from our own work to discuss the prospects for future research. We envision that future design technologies will develop from current and traditional conventions of practice combined with forward looking application of emerging technologies. In HCI, pen based interaction will allow architects to use the pencil again, without sacrificing the added power of computer aided design tools, and speech recognition will begin to play a role in capturing and retrieving design critique and discussion. In CSCW, a new generation of applications will address the needs of designers more closely than current general purpose meeting tools. In VR, applications are possible that use the technology not simply to provide a sense of three-dimensional presence, but that organize design information spatially, integrating it into the representation of artifacts and places.

title Um olhar sobre a relação entre sujeitos e meios técnicos: O público como construção social mediada [Looking at the relationship between subjects and technical means: The audience as mediated social construction]
source SIGraDi 2016 [Proceedings of the 20th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Argentina, Buenos Aires 9 - 11 November 2016, pp.872-879
summary This article analyses some of the proposals produced in the late 1970´s by the American contemporary artist Dan Graham, in which he uses technical means to investigate the audience´s perception and behavior. The questions raised highlight reciprocity phenomena and identity constructions – factors that affect our experience and behavior in contemporary cities daily life. All of these issues derive from Graham´s investigations of the main information and communication technologies (media) produced at that time, and which continue to offer reflections on current relationship between technical means and the subject – that is, his/her condition as audience, observer, spectator or user.

summary The paper will present one specific aspect of the PhD research called Cibersemiótica e Processos de Projeto: Metodologia em Revisão, funded by FAPESP, which in turn is linked to the Nomads.usp research group of the University of São Paulo. The paper discusses the relevance of communication and information management in the digital design processes from the synchronic study of concepts such as feedback loop, control and self-regulation. These concepts are present in both biosemiotic and interactive design of functional cycle proposed in 1934 by biologist Jakob von Uexküll, as in cybernetic development proposed by Gordon Pask in his sophisticated Conversation Theory in the early 1970’s.

title Indexing the Electronic Sketchbook: Diagrams as Keys to Visual Databases
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The question is how to index a visual database. Consider a visual database -- collection of drawings, three-dimensional models, scanned photographs, video, and text -- as a kind of modernmultimedia architectural sketchbook. It can be shared among a wide group of users with different purposes, and who may think about the contents in rather different ways. The connections -- perhaps hypertext -- among the entries may be complex and the organization difficult to comprehend. How then, to index the collection? Certainly traditional techniques -- looking for a concert hail -- built of concrete and glass -- in the 1970's in Utrecht and the architect's name is H* -- will help. But suppose we do not know so precisely what we are looking for? Might we appeal to the language of diagram? Can we add to our schemes for search and retrieval a diagrammatic index? We propose to try this idea. The paper describes our "computer as cocktail napkin" system for recognizing and interpreting diagrams. It consists of a pen-based freehand sketching program that recognizes simple symbols the user has trained (such as lines, shapes, letters, etc.) and spatial arrangements of these symbols. A graphical search procedure finds occurrences of a drawn configuration of symbols in the pages of a sketchbook made using the program. By extending thepages of the sketchbook to include photos, drawings, and text in addition to diagrams, we can use this technique to find items whose diagrams match a drawn search configuration. The paper will demonstrate this prototype program and explore its use for indexing visualdatabases in architecture.

title Pattern Language and Embedded Knowledge in Building Information Modeling
doi https://doi.org/10.52842/conf.ecaade.2007.457
source Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 457-464
summary When Christopher Alexander (1977), trained both as a mathematician and an architect, published his seminal work “The Pattern Language” in the 1970’s and introduced the concept of “pattern language”, computers were still in their infancy, CAD did not exist as we know it today, and computer information modeling was not even in the radar screen of researchers. Design communication simply meant manual drafting. With the concept of ‘pattern language” (http://www.patternlanguage.com/), Alexander proposed a systematic method for dealing with complexity, which proved itself to be more relevant than ever in the digital age. The concept is often cited by computer scientists as a precursor to object oriented modeling. This study explores the potential of “pattern language” for structuring building information and design knowledge within the framework of the recent developments in building information modeling (BIM). In this article, comparisons to the approach taken by the software engineering industry who embraced the idea of “patterns” as a systematic way to software development are also made. While Alexander’s pattern language proposes a method with which the designer can incorporate his/her experiences and design vision systematically into the process of designing, software industry’s approach to patterns describes a method for providing problem and solution patterns (i.e. prototypes) that can be used repeatedly during software development. There is obviously a significant difference between the original intent of the “pattern language” and the way it was later used in other fields including software engineering and business solutions. At the cross section of architectural design and software engineering, Building Information Modeling (BIM) software can benefit from carefully incorporating a combination of these two approaches into its structure as patterns.

summary Dan Graham became an important reference in contemporary art developing since the 1960´s a series of works that maintain a profound relation with urban cultural phenomena. This article proposes the analysis of his works produced over the 1970´s and 1980´s which presents the use of technical supports like video, exhibition and surveillance systems and which guided his earlier aesthetic research – related to the “institutional critique” – to the investigations about the power relations between objects, public and the space where they are placed.

title A Multi-dimensional Exploration of Urban Attributes by Data Mining
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. 333-350.
summary The paper which is proposed here will introduce an ongoing research project aiming to research data mining as a methodology of knowledge discovery in urban feature analysis. To address the increasing multi-dimensional and relational complexity of urban environments requires a multidisciplinary approach to urban analysis. This research is an attempt to establish a link between knowledge discovery methodologies and automated urban feature analysis. Therefore, in the scope of this research we apply data mining methodologies for urban analysis. Data mining is defined as to extract important patterns and trends from raw data (Witten and Frank, 2005). When applied to discover relationships between urban attributes, data mining can constitute a methodology for the analysis of multi-dimensional relational complexity of urban environments (Gil, Montenegro, Beirao and Duarte, 2009) The theoretical motivation of the research is derived by the lack of explanatory urban knowledge which is an issue since 1970’s in the area of urban research. This situation is mostly associated with deductive methods of analysis. The analysis of urban system from the perspective of few interrelated factors, without considering the multi-dimensionality of the system in a deductive fashion was not been explanatory enough. (Jacobs, 1961, Lefebvre, 1970 Harvey, 1973) To address the multi-dimensional and relational complexity of urban environments requires the consideration of diverse spatial, social, economic, cultural, morphological, environmental, political etc. features of urban entities. The main claim is that, in urban analysis, there is a need to advance from traditional one dimensional (Marshall, 2004) description and classification of urban forms (e.g. Land-use maps, Density maps) to the consideration of the simultaneous multi-dimensionality of urban systems. For this purpose, this research proposes a methodology consisting of the application of data mining as a knowledge discovery method into a GIS based conceptual urban database built out of official real data of Beyoglu. Generally, the proposed methodology is a framework for representing and analyzing urban entities represented as objects with properties (attributes). It concerns the formulation of an urban entity’s database based on both available and non-available (constructed from available data) data, and then data mining of spatial and non-spatial attributes of the urban entities. Location or position is the primary reference basis for the data that is describing urban entities. Urban entities are; building floors, buildings, building blocks, streets, geographically defined districts and neighborhoods etc. Urban attributes are district properties of locations (such as land-use, land value, slope, view and so forth) that change from one location to another. Every basic urban entity is unique in terms of its attributes. All the available qualitative and quantitative attributes that is relavant (in the mind of the analyst) and appropriate for encoding, can be coded inside the computer representation of the basic urban entity. Our methodology is applied by using the real and official, the most complex, complete and up-to-dataset of Beyoglu (a historical neighborhood of Istanbul) that is provided by the Istanbul Metropolitan Municipality (IBB). Basically, in our research, data mining in the context of urban data is introduced as a computer based, data-driven, context-specific approach for supporting analysis of urban systems without relying on any existing theories. Data mining in the context of urban data; • Can help in the design process by providing site-specific insight through deeper understanding of urban data. • Can produce results that can assist architects and urban planners at design, policy and strategy levels. • Can constitute a robust scientific base for rule definition in urban simulation applications such as urban growth prediction systems, land-use simulation models etc. In the paper, firstly we will present the framework of our research with an emphasis on its theoretical background. Afterwards we will introduce our methodology in detail and finally we will present some of important results of data mining analysis processed in Rapid Miner open-source software. Specifically, our research define a general framework for knowledge discovery in urban feature analysis and enable the usage of GIS and data mining as complementary applications in urban feature analysis.

title Learner-Centered Design: The Challenge for HCI in the 21st Century
source Interactions , no. April (1994): 36-48
summary In the 1980's a major transformation took place in the computing world: attention was finally being paid to making computers easier-to-use. You know the history: in the 1970's folks at Xerox were exploring so-called personal computers and developing graphical, point-and-click interfaces. The goal was to make using computers less cognitively taxing, there- by permitting the user to focus more mental cycles on getting the job done. For some time people had recognized that there would be benefits if users could interact with computers using visual cues and motor movements instead of testu- al/linguistic strings. However, computer cycles were costly; they could hardly be wasted on supporting a non-textual interface. There was barely enough zorch (i.e., computer power, measured in your favorite unit) to simply calculate the payroll.

title Dislocations of the spatial experience: From earthwork to liquid architecture [Deslocamentos da experiência espacial: De earthwork a arquitetura líquida]
source SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 423-427
summary This article reflects about the contemporary notion of “spatial experience” that can be drawn by means of the emergence of the “expanded field” in arts (Rosalind Krauss, 1979). For a perspective view of this notion and for its problematization in the current time we pretend to stablish a counterpoint between two historic moments related to the expansion of the spatial field and its experience: the 1960´s, with the focus on the immanent space by artistic propositions, and nowadays, with the ocurrence of “fusional fields” of art-architecture-landscape-digital media. We adopt as strategy to construct the question, the approximation of two paradigmatic works for their respective epochs: the “earthwork” Spiral Jetty of Robert Smithson, constructed in 1970 in the Great Salt Lake (Utah, USA) and the ephemeral architecture of Blur Building of Elizabeth Diller and Ricardo Scofidio, constructed in 2002 in the Lake Neuchatel, for the Suiss Expo (Yverdon-les-Bains – Suiss).

summary This paper studies houses built between 1930 and 1970 in southern Brazil. It is a large collection of projects, which has been systematized for publishing on a website and in digital media. The aim is to discuss the form of organization and systematization of this collection, which involved the construction of conceptual digital graphics. It emphasized the adoption of the concepts of type and model in the organization of the collection, which required a formal abstraction of the objects. The construction of conceptual graphics proved to be an effective tool in the process of abstraction. Moreover, such graphics have become more didactic material, enabling a better understanding of the universe studied.

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.

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 24-32.
summary Text-to-image generators, such as Midjourney, DALL-E, and Stable Diffusion, are becoming increasingly popular. These generators, whose models are trained on large datasets of text-image pairs, often scraped from the web, take text prompts as input, and use them to generate images—text-to-image prompting. In this visual essay, we raise questions about the entanglement of semiotics, semantics, syntax, and society in these text-to-image generator tools. We are intrigued by how these technologies are “intrawoven” with social and cultural contexts. How are their constructions and presentations reconfigurations? How do, or might they, inform pedagogy, theory, methods, and our publics? To explore these questions, we entered six prompts related to the built environment in six different languages, eight months apart in Midjourney (“Midjourney” n.d.). The generated images (Figure 1), require that we ask deep questions of each image, in comparison with each other, across each group of four, and across time (eight months apart). We argue that text-to-image generators call for a rigorous exploration of semiotics, semantics, syntax, and the society, with implications for pedagogy, theory-building, methodologies, and public enlightenment. Furthermore, we assert that these tools can facilitate pertinent questions about the relationships between technology and society. This is just the beginning. For now, we have questions.

summary Several research projects (Gramazio et al. 2014; Willmann et al. 2015; Helm et al. 2017; Adel et al. 2018; Adel Ahmadian 2020) have investigated the use of automated assembly technologies (e.g., industrial robotic arms) for the fabrication of nonstandard timber structures. Building on these projects, we present a novel and transferable process for the robotic fabrication of bespoke timber subassemblies made of off-the-shelf standard timber elements. A nonstandard timber structure (Figure 2), consisting of four bespoke subassemblies: three vertical supports and a Zollinger (Allen 1999) roof structure, acts as the case study for the research and validates the feasibility of the proposed process.

summary This paper presents a new approach for intuitive and effective design of periodic symmetric tiles. We observe that planar graphs can effectively represent symmetric tiles and graph drawing provides an intuitive paradigm for designing symmetric tiles. Moreover, based on our theoretical work to represent hexagonal symmetry by rectangular symmetry, we are able to present all symmetric tiles as graphs embedded on a torus and based on simple modulo operations. This approach enables us to develop a simple and efficient algorithm, which has been implemented in Java. By using this software, designers, architects and artists can create interesting symmetric tiles directly on the web. We also have designed a few examples of symmetric tiles to show the effectiveness of the approach.

title Modeling irregular and complex forms

summary Computational technologies provide arguably the first real opportunity architectural design has had for a comprehensive description of built form. With the advent of affordable computer-aided design systems (including drafting, modeling, visualization and simulation tools), architects believe they can be in full control of geometric aspects and, through these, of a wide spectrum of other aspects that are implicit or explicit in the geometric representation. This belief is based primarily on the efficiency and effectiveness of computer systems, ranging from the richness and adaptability of geometric primitives to the utility of geometric representations in simulations of climatic aspects. Such capabilities support attempts to design and construct more irregular or otherwise complex forms. These fall under two main categories: (1) parsing of irregularity into elementary components, and (2) correlation of the form of a building with complex geometric structures.The first category takes advantage of the compactness and flexibility of computational representations in order to analyse the form of a design into basic elements, usually elementary geometric primitives. These are either arranged into simple, unconstrained configurations or related to each other by relationships that define e.g. parametric relative positioning or Boolean combinations. In both cases the result is a reduction of local complexity and an increase of implicit or explicit relationships, including the possibility of hierarchical structures.The second category attempts to correlate built form with constraints that derive usually from construction but can also be morphological. The correlation determines the applicability of complex geometric structures (minimally ruled surfaces) to the description of a design. The product of this application is generally variable in quality, depending upon the designer's grounding in geometry and his ability to integrate constraints from different aspects in the definition of the design's geometry.Both categories represent a potential leap forward but are also equally hampered by the rigidity of the implementation mechanisms upon which they rely heavily. The paper proposes an approach to making these mechanisms subordinate to the cognitive and technical aspects of architectural thinking through fuzzy modeling. This way of modeling involves a combination of (a) canonical forms, (b) tolerances around canonical forms and positions, (c) minimal and maximal values, (d) fuzzy boundaries, and (e) plastic interaction between elements based on the dual principles of local intelligence and autonomy. Fuzzy models come therefore closer to the intuitive manners of sketching, while facilitating transition to precise and complex forms. The paper presents two applications of fuzzy modeling. The first concerns the generation of schematic building layouts, including adaptive control of programmatic requirements. The second is a system for designing stairs that can adapt themselves to changes in their immediate environment through a fuzzy definition of geometric and topological parametrization.

title Simulation of Micro Pedestrian Behaviour in Shopping Streets

summary Over the years, scholars have developed various models of pedestrian movement. These models can be used to assess the effects of detailed design decisions or to predict pedestrian behaviour under conditions of crowding. To date, not much attention has been paid to pedestrians' shopping behaviour at the micro level. Therefore, the main purpose of this project is to test a model that aims at simulating micro pedestrian behaviour in shopping streets, including entering shops. The model assumes a detailed network of links to represent the structure of street segments and entrances to the shops. The basic principle underlying the model is that a pedestrian moves from one link in the network to another, adjacent link. In fact, a pedestrian enters a segment at one side, heading for the other side of the segment. However, a pedestrian might enter the segment by leaving a shop as well. Then, the pedestrian might be heading for either side of the segment. While transferring from the current link to the next link, the pedestrian will be attracted by the shops along both sides of the street. The study area is Antwerp's main shopping street. During a one-week workshop in July 2004, students observed pedestrian movement in this shopping street. An inventory of some physical characteristics of the shopping street was made and pedestrians were tracked through two separate segments of the shopping street. In total, 334 pedestrians were tracked. A conventional multinomial logit model is used to simulate pedestrians' micro behaviour. The process of consecutively selecting links continues until the pedestrian has reached one of the terminal links or a shop. The model performs very well. Simulated routes were used to assess the validity of the model. Observed and simulated link loading correspond fairly well, however, the model seems to slightly mispredict the attraction of a number of shops.
