title	Sketching interpretation in novice and expert designers
source	Gero, J.S. and Tversky, B. (Eds.), Visual and Spatial Reasoning in Design , Key Centre of Design Computing and Cognition, University of Sydney, Sydney, Australia, pp. 209-220
summary	This paper focuses on the differences in visual reasoning between a novice and an expert architectural designer during the conceptual design process. The cognitive actions of each designer while sketching were categorized into four main groups (each consisting of a number of sub-groups): physical, perceptual, functional, and conceptual. Based on this analysis, we found that the expert differs markedly from the novice in productivity in terms of the number of sketches and the number of alternative ideas. We focused on the differences between them in terms of the frequencies of cognitive actions, with the hypothesis that the difference in productivity could be attributed to the differences in some or all types of cognitive actions. Differences between the expert and the novice were found for revising features (in the subcategory of drawing actions in the physical action category), for paying attention to the relations of depicted elements (perceptual category) and for the rates of new and revisited functions (functional category). These results are discussed in terms of the types of visual reasoning processes that could be involved in expert design and the possible implications of these results if they can be demonstrated to be characteristic of expert designers generally.

title	The light and colour significance in urban environment perception
source	Simulation of Architectural Space - Color and Light, Methods and Effects [Proceedings of the 4rd European Architectural Endoscopy Association Conference / ISBN 3-86005-267-5] Dresden (Germany), 29 September - 1 October 1999, pp. 50-56
summary	My contribution deals with light and colour effects in wider dimensions of architecture. It analyses their significance in urban environment perception from the application aspect of progressive tools of its forming and creative completion, i.e. the perceptual homomorphous iconic simulations in laboratory conditions. The work focuses on questions of light and colour perception, showing several principles and phenomena valid in visual perception systems. The structure of the perceived picture is interpreted in its four components: colour, motion, form and spaciousness. Each of the components is shown with relevant biological reactions and their reflections in subjective perception processes. The selected image examples document some manifestations of urbanistic structures and spaces experience transformation in natural and artificial lighting conditions. The emphasis of my contribution lies on some demonstrations from the laboratory experiment in investigating the illumination and colour influence on the architectural design quality, and on examples of alternative methods of visual interpretation on endoscopic modelling simulation outputs. The conclusion of my work formulates some knowledge and statement of objective colour and light modelling simulation assets in architectural design quality.

title	A perceptually based physical error metric for realistic image synthesis
source	Alyn Rockwood, editor, SIGGRAPH 99 Conference Proceedings, Annual Conference Series, ACM SIGGRAPH, Addison Wesley
summary	We introduce a new concept for accelerating realistic image synthesis algorithms. At the core of this procedure is a novel physical error metric that correctly predicts the perceptual threshold for detecting artifacts in scene features. Built into this metric is a computational model of the human visual system's loss of sensitivity at high background illumination levels, high spatial frequencies, and high contrast levels (visual masking). An important feature of our model is that it handles the luminance-dependent processing and spatiallydependent processing independently. This allows us to precompute the expensive spatially-dependent component, making our model extremely efficient. We illustrate the utility of our procedure with global illumination algorithms used for realistic image synthesis. The expense of global illumination computations is many orders of magnitude higher than the expense of direct illumination computations and can greatly benefit by applying our perceptually based technique. Results show our method preserves visual quality while achieving significant computational gains in areas of images with high frequency texture patterns, geometric details, and lighting variations.

title	Situatedness: A New Dimension for Learning Systems in Design
doi	https://doi.org/10.52842/conf.ecaade.1999.252
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 252-261
summary	In this paper we adopt the approach that designing is a series of situated acts, ie designing cannot be pre-planned to completion. This is based on ideas from situated cognition theory that claims that what people perceive, how they conceive and what they do develop together and are adapted to the environment. For a system to be useful for human designers it must have the ability to associate what is learned to its environment. In order for a system to do that such a system must be able to acquire knowledge of the environment that a design constructs. Therefore, acknowledging the notion of situatedness is of importance to provide a system with such capability and add on a new dimension to existing learning systems in design. We will call such a learning system within the design domain a Situated Learning Design System (SLDS). A SLDS should be able to create its own situational categories from its perceptual experiences and modify them if encountered again to link the learned knowledge to its corresponding situation. We have chosen architectural shapes as the vehicle to demonstrate our ideas and used multiple representations to build a platform for a SLDS to learn from. In this paper the notion of situatedness and its role in both designing and learning is discussed. The overall architecture of a SLDS is introduced and how the potential outcome of such a system will support human designers while designing is discussed.

title	How an Architect Created Design Requirements
source	G. Goldschmidt and W. Porter (eds), Design Thinking Research Symposium: Design Representation, MIT, Cambridge, pp. II.101-124
summary	There is an anecdotal view that designers, during a conceptual design process, not just synthesise solutions that satisfy initially given requirements, but also create by themselves novel design requirements that capture important aspects of the given problem. Further, it is believed that design sketches serve as a thinking tool for designers to do this. Then, what kinds of cognitive interaction with their own sketches enable designers to create novel requirements? The purpose of this paper is to answer this question. We examined the cognitive processes of a practising architect, using a protocol analysis technique. Our examinations focused on whether particular types of cognitive actions account for the creation of novel design requirements. We found that intensive occurrences of a certain type of perceptual actions, acts of establishing new relations or visual features on the sketches, are likely to co-occur with the creation of requirements. This suggests that this type of perceptual actions are the key constituent of acts of creating novel requirements, and therefore one of the important actions in sketching activities. This presents evidence of the view that designing is a situated act, as well as has an implication for design education.

title	Are theories of imagery theories of imagination? An active perception approach to conscious mental content
source	Cognitive Science 23(2): 207-245
summary	Can theories of mental imagery, conscious mental contents, developed within cognitive science throw light on the obscure (but culturally very significant) concept of imagination? Three extant views of mental imagery are considered: quasi-pictorial, description, and perceptual activity theories. The first two face serious theoretical and empirical difficulties. The third is (for historically contingent reasons) little known, theoretically underdeveloped, and empirically untried, but has real explanatory potential. It rejects the "traditional" symbolic computational view of mental contents, but is compatible with recent and approaches in robotics. This theory is developed and elucidated. Three related key aspects of imagination (non-discursiveness, creativity, and ) raise difficulties for the other theories. Perceptual activity theory presents imagery as non-discursive and relates it closely to . It is thus well placed to be the basis for a general theory of imagination and its role in creative thought.

title	The Art of Emergence
source	International Conference on Generative Art
summary	Since several years, the term emergence is mentioned in the paradigm of chaos and complexity. Following this approach, complex system constituted by multitude of individual develop global behavioral properties on the base of local chaotic interactions (self-organization). These theories, developed in scientific and philosophical milieus are rapidly spreading as a "way of thinking" in the several fields of cognitive activities. According to this "way of thinking" it is possible revise some fundamental themes as the economic systems, the cultural systems, the scientific paths, the communication nets under a new approach where nothing is pre-determined, but the global evolution is determined by specific mechanisms of interaction and fundamental events (bifurcation). With a jump in scale of the life, also other basic concepts related to the individuals as intelligence, consciousness, psyche can be revised as self-organizing phenomena. Such a conceptual fertility has been the base for the revision of the artistic activities as flexible instruments for the investigation of imaginary worlds, metaphor of related real worlds. In this sense we claim to the artist a role of "researcher". Through the free exploration of new concepts, he can evoke qualities, configurations and hypothesis which have an esthetical and expressive value and in the most significant cases, they can induce nucleation of cultural and scientific bifurcation. Our vision of the art-science relation is of cooperative type instead of the conflict of the past decades. In this paper we describe some of the most significant realized artworks in order to make explicit the concepts and basic themes. One of the fundamental topics is the way to generate and think to the artwork. Our characterization is to see the artwork not as a static finished product, but as an instance or a dynamic sequence of instances of a creative process which continuously evolves. In this sense, the attention is focused on the "generative idea" which constitutes the envelop of the artworks generable by the process. In this approach the role of technology (computers, synthesizers) is fundamental to create the dimension of the generative environment. Another characterizing aspect of our artworks is derived by the previous approach and specifically related to the interactive installations. The classical relation between artist, artwork and observers is viewed as an unidirectional flux of messages from the artist to the observer through the artwork. In our approach artist, artwork and observer are autonomous entities provided with own personality which jointly intervene to determine the creative paths. The artist which generate the environment in not longer the "owner" of the artwork; simply he dialectically bring the generative environment (provided by a certain degree of autonomy) towards cultural and creative "void" spaces (not still discovered). The observers start from these platforms to generate other creative paths, sometimes absolutely unexpected , developing their new dialectical relations with the artwork itself. The results derived by these positions characterize the expressive elements of the artworks (images, sequences and sounds) as the outcomes of emergent behavior or dynamics both in the sense of esthetical shapes emergent from fertile generative environments, either in terms of emergent relations between artist, artwork and observer, either in terms of concepts which emerge by the metaphor of artificial worlds to produce imaginary hypothesis for the real worlds.

title	ArchiDATA: A Hypermedia Tool for Architecture
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 496-500
summary	Design is a cooperative activity at several levels. At one level, clients, architects, financiers, and construction engineers and contractors, all play important roles in creating the design for the building. At another level, the design team may contain architects, interior and landscape designers, lighting experts, heating, ventilation, and air-conditioning experts, etc. At a third level, individual architects cooperate with computer-based design tools in creating portions of a complex design. This paper describes an ongoing project called ArchiDATA, in which we are developing a computational Case-Based Design Aid (CBDA) for architectural design. This project, which is collaboration between cognitive scientists and architectural researchers, builds on an artificial intelligence paradigm called case-based reasoning and work in post-occupancy evaluation and other case study research in architecture.

source	Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 260-271
summary	Much interest has been recently devoted to generative processes in design. Advances in computational tools for design applications, coupled with techniques from the field of artificial intelligence, have lead to new possibilities in the way computers can inform and actively interact with the design process. In this paper we use the concepts of generative and goal-oriented design to propose a computer tool that can help the designer to generate and evaluate certain aspects of a solution towards an optimized behavior of the final configuration. This work focuses mostly on those aspects related to the environmental performance of the building. Genetic Algorithms are applied as a generative and search procedure to look for optimized design solutions in terms of thermal and lighting performance in a building. The Genetic Algorithm (GA) is first used to generate possible design solutions, which are then evaluated in terms of lighting and thermal behavior using a detailed thermal analysis program (DOE2.1E). The results from the simulations are subsequently used to further guide the GA search towards finding low-energy solutions to the problem under study. Solutions can be visualized using an AutoLisp routine. The specific problem addressed in this study is the placing and sizing of windows in an office building. The same method is applicable to a wide range of design problems like the choice of construction materials, design of shading elements, or sizing of lighting and mechanical systems for buildings.

title	Artificial Music Composer
source	International Conference on Generative Art
summary	Traditional Musical Computation Systems had to face the differences between the computational techniques and the characteristics of musical creation. Characteristics such as a high degree of subjectivity, a great irrational component, and a learning process based on the use of examples and environmental absorption, have made music difficult to be formalized through algorithmic methods or classical Artificial Intelligence methods such as Expert Systems. We propose the creation of a cybernetic model of a human composer in a primeval stage of human musical evolution, following a paradigm of cognitive complex models creation, based on the use of the human reference, not only in a static point of view but also considering its evolution through time. Therefore, the proposed system simulates musical creation in one of the first stages of musical evolution, whose main characteristics are the percussive and choral aspects. The system is based on Genetic Algorithms, whose genetic population is integrated by several tribes. This model carries out the task of musical composition, led by the user who expresses his/her musical taste assigning a punctuation to each tribe. The GA selects the worse tribes as individuals to be eliminated. In order to select those tribes which are going to be used as parents, a random function is used, having each tribe a probality proportional to its punctuation. The new tribe is produced by crossing the parent tribes in each individual. Afterwards, mutation takes place in the created individuals. The experiments carried out with this system have proved its functionality in the composition of rhythmic patterns. It is intended to enlarge the experiment's scope by communicating the system via Internet. This would enable its use by users of different musical cultures, taking into account that the system is user-friendly, since it requires no musical knowledge.

title	A Virtual Reality User Interface for a Design Information System, CCAI: the Journal for the Integrated Study of Artificial Intelligence
source	Cognitive Science and Applied Epistemology, Rijks Universiteit Gent
summary	The computer is a tool, a complex artefact that is used to extend our reach. A computer system can provide several kinds of services, but against these services stands a supplementary task that the user must deal with: the communication with the computer system. We argued that Virtual Reality (VR) can fundamentally improve the user interface by rendering on the common experiential skills of all users. We present the theoretical basis for this, referring to Donald Norman's theory. We show that VR provides at least theoretically, the means to take a big step in the direction of an ideal user interface. As an example of a innovative application of VR in user interface design, we presented the VR-DIS system; an interdisciplinary design system for the building and construction industry. We discuss the issues underlying the design of its VR interface.

title	Technoromanticism - digital narrative, holism, and the romance of the real
source	MIT Press
summary	It's no secret that contemporary culture romanticizes digital technologies. In books, articles, and movies about virtual community, virtual reality, artificial intelligence, artificial life, and other wonders of the digital age, breathless anticipation of vast and thrilling changes has become a running theme. But as Richard Coyne makes clear in Technoromanticism: Digital Narrative, Holism, and the Romance of the Real, a dense but rewarding piece of academic criticism, we also get romantic about the new technologies in a more rigorous sense of the word. Whether heralding an electronic return to village communalism or celebrating cyberspace as a realm of pure mind, today's utopian thinking about the digital, Coyne argues, essentially replays the 18th- and 19th-century cultural movement called Romanticism, with its powerful yearnings for transcendence and wholeness. And this apparently is not a good thing. Romanticism, like the more sober Enlightenment rationalism against which it rebelled, has outlived its usefulness as a way of understanding the world, Coyne argues. And so he spends the duration of the book bombarding both the romantic and the rationalist tendencies in cyberculture with every weapon in the arsenal of 20th-century critical theory: poststructuralism, Freudianism, postmodern pragmatism, Heideggerian phenomenology, surrealism--Coyne uses each in turn to whack away at conventional wisdoms about digital tech. Whether the conventional wisdoms remain standing at the end is an open question, but Coyne's tour of the contemporary intellectual landscape is a tour de force, and never before has digital technology's place in that landscape been mapped so thoroughly. --

summary	This paper presents an application of swarm intelligence towards the problem of spatial configuration. The methodology classifies activities as discrete entities, which self-organise topologically through associational parameters: an investigation of emergent route formation and spatial connectivity based on simple agent and pheromone interaction, coupled with the problem of ‘loose’ rectangular geometric assembly. A concept model sniffingSpace (Ireland, 2009) developed in Netlogo (Willensky, 1999), which established the self-organising topological capacity of the system, is extended in Processing (Fry & Rea, 2009) to incorporate rectangular geometry towards the problem of planning architectural space.

summary	In the age of information technology, architectural design problems become increasingly complex, the finding of optimal solutions has become more difficult and obscure. Computer-aided design techniques have been applied to solve these ill-structured design problems; however, most of these applications have been used for graphical automation. Design improvement in quality has not been achieved using traditional computer programs. To handle the critical design decision problems, design systems need to be structured based on theoretical problem solving models. This would enable the design system to handle the problem solving design knowledge as well as the various technological aspects and geometrical representations. A theoretical model, knowledge-aided design, is proposed. Knowledge-aided design is a conceptual and theoretical model based on fundamental principles of design. It provides a problem-solving environment and a procedure for knowledge-based computer-aided architectural design based on cognitive science and artificial intelligence techniques. As a partial implementation of the theoretical model, the development of knowledge-aided design system for intelligent building design is described.

title	Using Computer Game to Develop Advanced AI
source	Computer, 34 (7), July pp. 70-75
summary	Although computer and video games have existed for fewer than 40 years, they are already serious business. Entertainment software, the entertainment industry's fastest growing segment, currently generates sales surpassing the film industry's gross revenues. Computer games have significantly affected personal computer sales, providing the initial application for CD-ROMs, driving advancements in graphics technology, and motivating the purchase of ever faster machines. Next-generation computer game consoles are extending this trend, with Sony and Toshiba spending $2 billion to develop the Playstation 2 and Microsoft planning to spend more than $500 million just to market its Xbox console [1]. These investments have paid off. In the past five years, the quality and complexity of computer games have advanced significantly. Computer graphics have shown the most noticeable improvement, with the number of polygons rendered in a scene increasing almost exponentially each year, significantly enhancing the games' realism. For example, the original Playstation, released in 1995, renders 300,000 polygons per second, while Sega's Dreamcast, released in 1999, renders 3 million polygons per second. The Playstation 2 sets the current standard, rendering 66 million polygons per second, while projections indicate the Xbox will render more than lOO million polygons per second. Thus, the images on today's $300 game consoles rival or surpass those available on the previous decade's $50,000 computers. The impact of these improvements is evident in the complexity and realism of the environments underlying today's games, from detailed indoor rooms and corridors to vast outdoor landscapes. These games populate the environments with both human and computer controlled characters, making them a rich laboratory for artificial intelligence research into developing intelligent and social autonomous agents. Indeed, computer games offer a fitting subject for serious academic study, undergraduate education, and graduate student and faculty research. Creating and efficiently rendering these environments touches on every topic in a computer science curriculum. The "Teaching Game Design " sidebar describes the benefits and challenges of developing computer game design courses, an increasingly popular field of study

source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 589-594
summary	In 1950, fifty years ago, Alan Turing published a much-quoted paper that has given rise to a long list of articles and books. It presented, perhaps for the first time, in a clever and somehow sarcastic way, what has become one of the main big questions raised by the use of computers in human societies. The title of that paper was "Computing Machinery and Intelligence" (Mind, Vol. LIX, No. 236, October 1950) and the game proposed in it, called by Turing "the imitation game" has come to be known as "Turing's Test". The paper presented here is a rather simple adaptation of Turing's Test. It may, I hope, present in a, perhaps, not too serious a way, some central points related to the way that computers have integrated themselves in architect's, engineer's and building enterprises and, through them, in the way that architecture evolves in our times and adapts itself to modern societies.

title	ArTbitrariness in Music
source	International Conference on Generative Art
summary	Evolution is now considered not only powerful enough to bring about the biological entities as complex as humans and conciousness, but also useful in simulation to create algorithms and structures of higher levels of complexity than could easily be built by design. In the context of artistic domains, the process of human-machine interaction is analyzed as a good framework to explore creativity and to produce results that could not be obtained without this interaction. When evolutionary computation and other computational intelligence methodologies are involved, every attempt to improve aesthetic judgement we denote as ArTbitrariness, and is interpreted as an interactive iterative optimization process. ArTbitrariness is also suggested as an effective way to produce art through an efficient manipulation of information and a proper use of computational creativity to increase the complexity of the results without neglecting the aesthetic aspects [Moroni et al., 2000]. Our emphasis will be in an approach to interactive music composition. The problem of computer generation of musical material has received extensive attention and a subclass of the field of algorithmic composition includes those applications which use the computer as something in between an instrument, in which a user "plays" through the application's interface, and a compositional aid, which a user experiments with in order to generate stimulating and varying musical material. This approach was adopted in Vox Populi, a hybrid made up of an instrument and a compositional environment. Differently from other systems found in genetic algorithms or evolutionary computation, in which people have to listen to and judge the musical items, Vox Populi uses the computer and the mouse as real-time music controllers, acting as a new interactive computer-based musical instrument. The interface is designed to be flexible for the user to modify the music being generated. It explores evolutionary computation in the context of algorithmic composition and provides a graphical interface that allows to modify the tonal center and the voice range, changing the evolution of the music by using the mouse[Moroni et al., 1999]. A piece of music consists of several sets of musical material manipulated and exposed to the listener, for example pitches, harmonies, rhythms, timbres, etc. They are composed of a finite number of elements and basically, the aim of a composer is to organize those elements in an esthetic way. Modeling a piece as a dynamic system implies a view in which the composer draws trajectories or orbits using the elements of each set [Manzolli, 1991]. Nonlinear iterative mappings are associated with interface controls. In the next page two examples of nonlinear iterative mappings with their resulting musical pieces are shown.The mappings may give rise to attractors, defined as geometric figures that represent the set of stationary states of a non-linear dynamic system, or simply trajectories to which the system is attracted. The relevance of this approach goes beyond music applications per se. Computer music systems that are built on the basis of a solid theory can be coherently embedded into multimedia environments. The richness and specialty of the music domain are likely to initiate new thinking and ideas, which will have an impact on areas such as knowledge representation and planning, and on the design of visual formalisms and human-computer interfaces in general. Above and bellow, Vox Populi interface is depicted, showing two nonlinear iterative mappings with their resulting musical pieces. References [Manzolli, 1991] J. Manzolli.

summary	Computer applications in design have pursued two main development directions: analytical modelling and information technology. The former line has produced a large number of tools for reality simulation (i.e. finite element models), the latter is producing an equally large amount of advances in conceptual design support (i.e. artificial intelligence tools). Nevertheless we can trace rare interactions between computation models related to those different approaches. This lack of integration is the main reason of the difficulty of CAAD application to the preliminary stage of design, where logical and quantitative reasoning are closely related in a process that we often call 'qualitative evaluation'. This paper briefly surveys the current development of qualitative physical models applied in design and propose a general approach for modelling physical behaviour by means of Bayesian network we are employing to develop a tutoring and coaching system for natural ventilation preliminary design of halls, called VENTPad. This tool explores the possibility of modelling the causal mechanism that operate in real systems in order to allow a number of integrated logical and quantitative inference about the fluid-dynamic behaviour of an hall. This application could be an interesting connection tool between logical and analytical procedures in preliminary design aiding, able to help students or unskilled architects, both to guide them through the analysis process of numerical data (i.e. obtained with sophisticate Computational Fluid Dynamics software) or experimental data (i.e. obtained with laboratory test models) and to suggest improvements to the design.

summary	Dunhuang Art Cave is confronted with the serious influence of natural forces. Integrating Multimedia, Artificial intelligence and CAD, we can virtually preserve and reproduce the original cave architecture, painting sculptures and murals. This paper first introduce the main ideas of Dunhuang cave virtual rebuilding, cave virtual navigating, mural color restoring as well as Dunhuang-style pattern designing, and then analyzes in detail their technical issues and show results of prototype systems. In the end, we give a brief summary.

summary	The paper reflects on a thirteen-year period of CAAD research and development by a small group of researchers and practitioners. Starting with simple algorithmic drafting programmes, the work transcended to expert systems and distributed artificial intelligence, using computers as tools. The research cycle is about to begin afresh; computers in the next century shall not be detached entities but the extensions of man. The computer shall be the medium that will enable a designer to be what he/she really is. This future has already begun.
