title	Understanding the User Interfaces Through Spatial Metaphors
source	García Amen, F, Goni Fitipaldo, A L and Armagno Gentile, Á (eds.), Accelerated Landscapes - Proceedings of the XXVII International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2023), Punta del Este, Maldonado, Uruguay, 29 November - 1 December 2023, pp. 1573–1584
summary	This study focuses on spatial metaphors in digital interfaces that designers use in their modeling processes. When designers themselves perform an action by using a digital tool, they often make spatial inferences without realizing it, with the help of their mental models and established modeling experiences. In order to trace these implicit spatial metaphors, the spatial metaphors used by the designers were discussed through their verbal expressions. Within the scope of the pilot case study, the participants told each other the 3D models given to them verbally, and the other participant made the 3D model simultaneously with the narrative. The metaphors that the participant in the role of the narrator used with the intention of making a spatial description allowed the participant in the role of the modeler to build spatial relations. This study, which has the potential to provide a spatial framework for interfaces in the future, is a step toward designing new user interface metaphors.

title	Semantic Roomobjects for Conceptual Design Support

summary	The conceptual design at the beginning of the building construction process is essential for the success of a building project. Even if some CAD tools allow elaborating conceptual sketches, they rather focus on the shape of the building elements and not on their functionality. We introduce semantic roomobjects and roomlinks, by way of example to the CAD tool ArchiCAD. These extensions provide a basis for specifying the organisation and functionality of a building and free architects from being forced to directly produce detailed constructive sketches. Furthermore, we introduce consistency analyses of the conceptual sketch, based on an ontology containing conceptual relevant knowledge, specific to one class of buildings.

title	Space is the Machine, with a Ghost Inside
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 157-173
summary	The purpose of this paper is to report efforts towards the construction of a model for urban spatial dynamics simulation, based on multi-agents and space. The underlying idea is to have urban space producers and consumers operating in a two-layer, two-circuit model. The first layer holds urban space and its successive transformations; a second layer contains agents related to space; the first circuit simulates space production, and a second one simulates space consumption. Relationship between layers is represented as objective spatial features that agents are submitted to (the machine) and subjective meanings agents attach to each spatial feature (the ghost). While space works always in the same way, meanings vary according to each agent’s background and context. Relationships between circuits are represented by means of a market game in which producers try to maximize their profits by gambling with their risks, whereas consumers try to foresee the spatial distribution of local externalities that maximizes their utilities and investments. Urban Spatial Features are captured through centrality and land use patterns; every single agent’s action leads to changes in both patterns. Producers’ profit is a function of built form location. Consumers’ local externalities are concerned basically with present and future services. The model iteration is twofold: first it generates and allocates a number of built forms within a previously determined spatial system (a cellular matrix, for example), and second it allocates users to built forms. Population of users have its social profile and growth rate externally determined. Built form allocation is decided on the basis of a combination of profitXrisk perspectives. Users’ locational choice is supported by accessibility to services and present/future neighbourhood profile. Built form allocation works as parameter for users’ locational assessment, whereas users’ choices are used as parameters for developers. The model tends to adjust itself, in terms of quantities and types of built forms to be erected, although through a market lag of some iterations. Allocations are always made through weighted draws, so that mutations (non deterministic allocations) do occur.

title	Built form and urban configuration development simulation
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	The "centrality/potential" model, proposed by Krafta (1994), for configurational development, aims at the simulation of inner city built form growth. This is generally achieved by simulating the uneven distribution of floor area increments, resulting from replacement of old buildings, considered "devalued capital" form new ones. The model considers two main variables - public urban space system and built form - and treats them unevenly; the former is extensively disaggregated whereas the latter is not. This feature enables the model to make just a rough account of intra-urban built form development. The issue of built form simulation is then taken further in the following way: a) Urban built form is disaggregated by types. Buildings are classified by a cross combination of scale, purpose, age and quality standard; b) The city is itself considered as a set of intertwined typologic cities. This means that each unit of public space is identified by its dominant built form type, producing a multilayered-discontinuous city. Each one has its own market characteristics: rentability, technological availability and demand size; c) The market constraints determine which layer-city has priority over the others, as well as each one's size of growth. References to rentability and demand size gives each built form type priorities for development d) Spatial conditions, in the form of particular evaluation of centrality and spatial opportunity measures, regulates the distribution of built form increments and typological succession. Locational values, denoted by centrality and spatial opportunity measures, area differently accounted for in each layer-city simulation. e) Simulation is obtained by "running" the model recursively. Each built form type is simulated separately and in hyerarquical order, so that priority and replacement of built form types is acknowledged properly.

title	Closing the Loop: From Analysis to Transformation within BIM
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 347-357.
summary	The shift from traditional CAD to BIM has created a significant potential to embed optimization processes in many stages of the design. The presented research is situated in the early design stage of inception and concept, focusing on analysis-driven-form-finding during the integrated design approach within a BIM environment. A custom analysis framework, has been developed and linked to a visual programming environment that allows the exchange of data with the parametric components of a BIM environment. The developed workflow and sequential split of functionalities enables a shared design environment for multiple experts and the design-team. The environment is intended to close the loop from analysis to parametric modeling in order to generate and evaluate building designs against performance criteria, with the aim to expedite the design decision process. The prototype has been presented to participants of the Deep-Space Cluster at SmartGeometry 2014.

title	Augmented Reality Design Decision Support Engine for the Early Building Design Stage
doi	https://doi.org/10.52842/conf.caadria.2015.231
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 231-240
summary	Augmented reality has come a long way and experienced a paradigm shift in 1999 when the ARToolKit was released as open source. The nature of interaction between the physical world and the virtual-world has changed forever. Fortunately for the AECO industry, the transition from traditional Computer Aided Design to virtual building design phrased as Building Information Modeling has created a tremendous potential to adopt Augmented Reality. The presented research is situated in the early design stage of project inception and focuses on supporting informed collective decision-making, characterized by a dynamic back and forth analytical process generating large amounts of data. Facilitation aspects, such as data-collection, storage and access to enable comparability and evaluation are crucial for collective decision-making. The current research has addressed these aspects by means of data accessibility, visualization and presentation. At the core of the project is a custom developed Augmented Reality framework that enables data interaction within the design model. In order to serve as a collaborative decision support engine, the framework also allows multiple models and their datasets to be displayed and exercised simultaneously. The paper demonstrates in the case study the successful application of the AR tool during collaborative design decision meetings.

title	Transducer: 3D Audio-Visual Form-Making as Performance
source	AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 285-291
summary	This paper describes Transducer, a prototype digital system for live, audio-visual performance. Currently the process of editing sounds or crafting three-dimensional structures on a computer remains a frustratingly rigid process. Current tools for real-time audio or visual construction using computers involve obtuse controls, either heavily GUI'ed or overstylized. Transducer asks one to envision a space where the process of editing and creating on a computer becomes a dynamic performance. The content of this performance may be sufficiently complex to elicit multiple interpretations, but Transducer enforces the notion that the process of creation should itself be a fluid and transparent expression. The system allows a performer to build constructions of sampled audio and computational three-dimensional form simultaneously. Each sound clip is visualized as a "playable" cylinder of sound that can be manipulated both visually and aurally in real-time. The transducer system demonstrates a creative space with equal design detailing at both the construction and performance phase.

title	The Digital Sketch Workshop: a Core Course in Design with Computation
source	AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 251-264
summary	This paper summarizes DIGITAL SKETCH, a workshop that took place over the course of two weeks in September 1998 at Designskolen Kolding, Denmark. DIGITAL SKETCH was an attempt to create a foundation course in design for the digital medium for students with strong visual design skills, but little to no computer experience. Teaching design on computers is commonly thought of as detailing the current version of the latest commercial software. As long as this is the case, design on computers will (quite rightfully) continue to get little respect from those designers using more traditional design methods. How can we find the "core" of this medium when faced with the constant onslaught of operating system upgrades and version 11.2 of software Y83? For DIGITAL SKETCH, we tried to demystify the process of controlling the computer. In this workshop we examined the meanings of the term "sketch" as it applies to the design process on the computer. Our hope was that by revealing some of the unique characteristics of the digital medium, we might develop new design processes in tune with this medium.

title	BAU: A Knowledge-Based System for the Investigation of a Basic Architectural Unit
source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 329-346
summary	The control of incremental complexities within an evolutionary design process has been a serious concern in both architectural education and practice. One method of examining this problem is to first define a "basic architectural unit" and a design environment which is composed of multiple units. Different levels of detail will be added to the unit as the design process continues. Secondly, a related computer program called BAU is introduced, which demonstrates that a computer is a meaningful tool for helping the architect to investigate the consequence of a design problem. Thirdly, both the domain expert's and the knowledge engineer's experiences during the development of BAU are described. Finally, the future direction of this research will be discussed.

source	Architectural Education and the Information Explosion [eCAADe Conference Proceedings] Zurich (Switzerland) 5-7 September 1987.
summary	Most of us will raise the question whether or not there will be any consequences at all beyond the increasing amount of communication systems which have to be taken into consideration in the design of a building. As an introduction into the subject, recent changes in the academic community as well as observations on the field of architecture will be introduced. Technological developments in Switzerland, Swissnet i.e. will be used to reinforce the assumption that telecommunication in its various forms may have or will have consequences for the work of the architects as well as for architecture education.

title	Mapping a Single Data Stream to Multiple Auditory Variables: A Subjective Approach to Creating a Compelling Design
source	Proceedings of the Third International Conferenceon Auditory Display, Santa FO Institute
summary	Representing a single data variable changing in time via sonification, or using that data to control a sound in some way appears to be a simple problem but actually involves a significant degree of subjectivity. This paper is a response to my own focus on specific sonification tasks (Kramer 1990, 1993) (Fitch & Kramer, 1994), on broad theoretical concerns in auditory display (Kramer 1994a, 1994b, 1995), and on the representation of high-dimensional data sets (Kramer 1991a & Kramer & Ellison, 1991b). The design focus of this paper is partly a response to the others who, like myself, have primarily employed single fundamental acoustic variables such as pitch or loudness to represent single data streams. These simple representations have framed three challenges: Behavioral and Cognitive Science-Can sonifications created with complex sounds changing simultaneously in several dimensions facilitate the formation of a stronger internal auditory image, or audiation, than would be produced by simpler sonifications? Human Factors and Applications-Would such a stronger internal image of the data prove to be more useful from the standpoint of conveying information? Technology and Design-How might these richer displays be constructed? This final question serves as a starting point for this paper. After years of cautious sonification research I wanted to explore the creation of more interesting and compelling representations.

summary	Evaluation theory and methodology will be discussed by focusing two issues: (i) the traditional evaluation in Sweden, considered as an established research activity; (ii) the contributions of recent POE and its theoretical and methodological implications. An important and crucial question is how the outcome of the different approaches can serve design and planning practice. The Swedish experiences are concentrated to the fields of housing, quality of life and social care.

title	THE FULL-SCALE LABORATORY IN LUND
source	Proceedings of the 1st European Full-Scale Workshop Conference / ISBN 87-88373-20-7 / Copenhagen (Denmark) 15-16 January 1987, pp. 7-17
summary	An often repeated statement of the nature of the result of our general construction activities in general says that any building and environmental arrangement could be seen as a pure experimental product. The building, in this sense, is nothing but one single full-scale experiment started afresh each time, unfortunately, we could add, without the consistent follow-up measures. In view of this way of understanding the building process you might deduce the interest in a more anticipating attitude.and behaviour, namely the mock-up method or the full-scale design process, based on the philosophy that in a situation of uncertainty you had better try before than after. An underlying presumption is, however, that generally there is a lack of knowledge about the consequences by transferring spatial and design ideas from. drawings to one to one realization. A lack of knowledge not only-among lay, people but also among professionals. The mock-up practice can also to the same extent be derived from a pure investigative interest with the aim to virtually analyze general or specific problems in the* relationship man and the built environment, particularly buildings and spatial settings on the micro level. That means the use of the full-scale method for the search for basic design knowledge. In this sense the mock-up activities started in Sweden.

title	Building Integration Tools for Collaborative Design
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	For many years, research in CAAD systems has been mostly oriented towards single environ-ments, thus restricting the designer to a static environment. In reality the activities of user designers constantly interact with other participants activities (i.e. a structural engineer, services engineer, etc.). For instance, the architect is heavily influenced by the nature of the structural engineering process. It defines the character and integration of the basic components in other words, design is a collaborative process carried out by several participants with a single overall objective. The separation of architectural and engineering aspects in building design has brought on isolated computer tools. These tools are not interchangeable, the situation demands for their integration, all the interaction are supported by the social aspect of members of group participa-ting in collaborating work. The benefits of sharing CAD tools and related data between all members of the design team are that everyone works on the same information, co-ordination is easier and more accurate, and there is a reduction in the amount of repetition, as the need to redraw information is eliminated. The result is an increase in the accuracy and speed of the production of drawings. The technological aspects to support collaborative work and in particular the interaction process in design, is the main work issue being carried out at Strathclyde University, Department of Architecture and Building Science, Glasgow, Scotland U.K.

title	The Virtual Building Simulator: a Post-Parametric Spatial Planning Environment
source	Proceedings of Construction Applications of Virtual Reality, Weimar, 2011
summary	The described research of Fraunhofer IAO and AEDAS CDR examines the potential of post-parametric computational design together with immersive methods like Virtual Reality. The industrial approach of frontloading identifies the early design stage as crucial for all subsequent processes and the overall sustainability of future building projects. There VR together with innovative planning simulation methods allow to manage building models as complex systems for long-term planning reliability from construction to building operation. The Virtual Building Simulator represents a prototype of a design platform where the designer-user can immersive himself via VR into the interactive spatial formation process. The process synthesizes parametric constraints with design intent and algorithmic behavioural logics.

source	Design and Representation [ACADIA ‘97 Conference Proceedings / ISBN 1-880250-06-3] Cincinatti, Ohio (USA) 3-5 October 1997, pp. 63-70
summary	This paper will describe a behavior based artificial intelligence experiment in computer generated architectural design and will explain the internal representations and procedures of an agent based autonomous system. This is a departure from traditional (AI and architectural) top-down approaches, allowing hundreds of agents to work simultaneously—building, manipulating, and dismantling their environment. Individual agents work in collaboration, in disjunction or autonomously. Architectural design is perhaps most commonly described by the architect as consisting of the ability to see the whole picture, to organize, to collect, to juggle, to manage, and to maintain multiple conflicting goals and values. Architecture by the preceding definition is hierarchical and top-down in nature. The agent based experiment in this paper presents an alternative design process, involving multiple autonomous agents acting distributively. The agents (objects) move through the design landscape, simultaneously collaborating, building, degenerating, and transforming their world.

title	The Codewriting Workbook: Creating Computational Architecture in AutoLISP
source	Princeton Architectural Press, New York
summary	Conceived as a primer for architects, artists and designers, The Codewriting Workbook introduces students and practitioners to basic programming concepts for computeraided design (CAD). Through a series of guided exercises using algorithmic functions, readers learn how to develop and write procedures for two-dimensional drawings and three-dimensional models. Each sequence of exercises starts with a simple concept and evolves into a family of possible solutions, including specifying and exploring a wide range of design alternatives, integrating parameters for controlling randomness, utilizing meteorological data, and developing complex patterns for laser-cutting and CNC-milling. Exercises are presented in AutoLISP, a widely accessible CAD programming environment. Forward by William J. Mitchell CD included, over 400 functions, 416 pages, 274 drawings

summary	This paper reviews two projects undertaken in a CAD programming course that demonstrate to the students how programs could be developed to investigate possible architectural forms. The projects highlight a very sequential approach to form investigation in using both common geometries and the introduction of randomness to control design rules. This approach stressed the development of rules and evaluating their results as a method to determine the next step to investigate. Equal importance was placed on the anticipated, as well as, the unexpected.

summary	A few years ago I began to investigate the concepts of art-to-part and single part custom manufacturing. The original designs had to created on a CAD system either manually or by algorithm and then machine produced without any manual intervention. Rapid prototyping and laser cutting technology were both reviewed and the later selected for possible use. I also had a long time interest in geometric design. At that time one of my CAD classes took some of there window designs, created from a complex series of overlapping circles, arcs, and splines, and had them laser cut. The results were astonishing.

title	The Art of Spirolaterals

source	Reinventing the Discourse - How Digital Tools Help Bridge and Transform Research, Education and Practice in Architecture [Proceedings of the Twenty First Annual Conference of the Association for Computer-Aided Design in Architecture / ISBN 1-880250-10-1] Buffalo (New York) 11-14 October 2001, pp. 408-409
summary	The web site includes a series of images which is part of a larger set investigating the formation of two-dimensional designs leading to three-dimensional architectural forms using basic mathematical concepts. While investigating fractals and space curves, a mathematical figure called a "spirolateral" was encountered. A spirolateral is based on a square spiral with increasing length of turns and the turns repeating themselves. The turns can be all in one direction or certain turns can go the opposite direction. Angles other than 90 degrees can be used. The most interesting of these are ones that close on themselves, not all do. Investigating a series of possible turning angles, number of turns, number of repeats, and trying all revered turns, I identified over 10,000 spirolaterals that closed. This web site displays over 300 such spirolateral designs. In addition to investigating spirolaterals composed of straight lines, a series was developed that curves them. These designs are based on spirolaterals that are curved by antiMercator, circular, and inversion transformations. Figure 1 displays the 460 spirolateral, 4 turns at 60 degrees. Figure 2 and 3 display the same spirolateral with the antiMercator and Circular transformations applied. This web site includes galleries displaying the great variety of spirolaterals, interactive JAVA routines to display a series of spirolaterals, as well as, developing your own design, a technical description of spirolaterals, and the data for all the displayed images. My overall interest is to investigate methods that can develop forms that are in one sense predictable, but have the strong element to generate the unexpected. Using custom software enables an approach that allows variations to be investigated in a repeatable way, this enabling me to fine tune an idea by repetition and experimentation.
