title "To See Ideas" or The Visualizing of Programmatic Data Reading Examples in Architecture and Town Planning
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Whether images are still in the mind, metaphors, sketches or icons, they play a crucial role. They have always been the heuristic pivot around which the process of artefact design organizes itself, particularly in architecture and town-planning. "To see ideas" through computer ideograms is to experiment an interesting and new direction for "pictural approach" supported design. Cognitive psychology emphasizes the important part played by mental images in reasoning, imagination in the working of human intelligence and the construction of mental images as cognitive factors underlying reasoning. It also points out how close computerized objects and mental schemata are. "To reason over a situation is first to remember or build some mental models of this situation; second to make those models work or simulate them in order to observe what would happen in different circumstances and then verify whether they fit the experiment data; third to select the best model, a tool meant to sustain and amplify the elaboration of mental models, which is a spontaneous activity". We introduce our exploration of the direct transmission of mental models through computer ideograms. We study the "operative" and the "expressive" aspects, and this allows us to analyze how some aspects in a field of knowledge are represented by ideograms, schemata, icons, etc. Aid to imagination, reasoning and communication by means of a graphic language must be limited to some figurative relevant aspects of the domain considered; it should not aim at a realistic simulation. Therefore, the important role played by icons and the spatial schematic representation of knowledge is emphasized. Our hypothesis is that an architectural concept does not result from an inductive process, but rather is built to solve problems through the direct representation of ideas with ideograms. An experiment was conducted with a graphic language, a dynamic scenography and actor-objects. The language allows one to build and visualize models from the various domains of knowledge of the object. The dynamic scenography can explore and simulate kinetically those models by means of staging various narrations and visual scenarios. The actor-objects play various and complementary parts in order to make the image explicit and link it with the concept. We distinguish between two parallel levels of reality in computer ideographics: one concerns the model, it represents the visualization of a graphic model at a particular moment and according to a particular representation, the other concerns the ideogram.

title Psychology of Early Design in Architecture
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Lately there has been a good deal of emphasis on the early stages of the design process, particularly by developers of computer aids and quantitative design models for both evaluation and generation of designs in a variety of domains. Yet, there is little understanding of the early design-process. While the early design process as manifested by human designers need not be the sole basis of the description of this phase, it certainly represents and important kernel of knowledge, especially for those who are interested in developing models, systems or merely interfaces for such systems. This paper focuses on the characterization of the psychology of the early design phase in architecture. It is described in terms of the general design strategies and problem solving tactics used; and is contrasted against some of the process characteristics that

title A Hypermedia Model for Supporting Energy Design in Buildings

summary Several studies have discussed the limitations of the available CAAD tools and have proposed solutions [Brown and Novitski 1987, Brown 1990, Degelman and Kim 1988, Schuman et al 1988]. The lack of integration between the different tasks that these programs address and the design process is a major problem. Schuman et al [1988] argued that in architectural design many issues must be considered simultaneously before the synthesis of a final product can take place. Studies by Brown and Novitski [1987] and Brown [1990] discussed the difficulties involved with integrating technical considerations in the creative architectural process. One aspect of the problem is the neglect of technical factors during the initial phase of the design that, as the authors argued, results from changing the work environment and the laborious nature of the design process. Many of the current programs require the user to input a great deal of numerical values that are needed for the energy analysis. Although there are some programs that attempt to assist the user by setting default values, these programs distract the user with their extensive arrays of data. The appropriate design tool is the one that helps the user to easily view the principal components of the building design and specify their behaviors and interactions. Data abstraction and information parsimony are the key concepts in developing a successful design tool. Three different approaches for developing an appropriate CAAD tool were found in the literature. Although there are several similarities among them, each is unique in solving certain aspects of the problem. Brown and Novitski [1987] emphasize the learning factor of the tool as well as its highly graphical user interface. Degelman and Kim [1988] emphasize knowledge acquisition and the provision of simulation modules. The Windows and Daylighting Group of Lawrence Berkeley Laboratory (LBL) emphasizes the dynamic structuring of information, the intelligent linking of data, the integrity of the different issues of design and the design process, and the extensive use of images [Schuman et al 19881, these attributes incidentally define the word hypermedia. The LBL model, which uses hypermedia, seems to be the more promising direction for this type of research. However, there is still a need to establish a new model that integrates all aspects of the problem. The areas in which the present research departs from the LBL model can be listed as follows: it acknowledges the necessity of regarding the user as the center of the CAAD tool design, it develops a model that is based on one of the high level theories of human-computer interaction, and it develops a prototype tool that conforms to the model.

title CONTEXTUALIZATION AND EMBODIMENT IN CYBERSPACE
doi https://doi.org/10.52842/conf.caadria.2004.005
source CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 5-14
summary The introduction of VRML (Virtual Reality Markup Language) in 1994, and other similar web-enabled dynamic modeling software (such as SGI’s Open Inventor and WebSpace), have created a rush to develop on-line 3D virtual environments, with purposes ranging from art, to entertainment, to shopping, to culture and education. Some developers took their cues from the science fiction literature of Gibson (1984), Stephenson (1992), and others. Many were web-extensions to single-player video games. But most were created as a direct extension to our new-found ability to digitally model 3D spaces and to endow them with interactive control and pseudo-inhabitation. Surprisingly, this technologically-driven stampede paid little attention to the core principles of place-making and presence, derived from architecture and cognitive science, respectively: two principles that could and should inform the essence of the virtual place experience and help steer its development. Why are the principles of place-making and presence important for the development of virtual environments? Why not simply be content with our ability to create realistically-looking 3D worlds that we can visit remotely? What could we possibly learn about making these worlds better, had we understood the essence of place and presence? To answer these questions we cannot look at place-making (both physical and virtual) from a 3D space-making point of view alone, because places are not an end unto themselves. Rather, places must be considered a locus of contextualization and embodiment that ground human activities and give them meaning. In doing so, places acquire a meaning of their own, which facilitates, improves, and enriches many aspects of our lives. They provide us with a means to interpret the activities of others and to direct our own actions. Such meaning is comprised of the social and cultural conceptions and behaviors imprinted on the environment by the presence and activities of its inhabitants, who in turn, ‘read’ by them through their own corporeal embodiment of the same environment. This transactional relationship between the physical aspects of an environment, its social/cultural context, and our own embodiment of it, combine to create what is known as a sense of place: the psychological, physical, social, and cultural framework that helps us interpret the world around us, and directs our own behavior in it. In turn, it is our own (as well as others’) presence in that environment that gives it meaning, and shapes its social/cultural character. By understanding the essence of place-ness in general, and in cyberspace in particular, we can create virtual places that can better support Internet-based activities, and make them equal to, in some cases even better than their physical counterparts. One of the activities that stands to benefit most from understanding the concept of cyber-places is learning—an interpersonal activity that requires the co-presence of others (a teacher and/or fellow learners), who can point out the difference between what matters and what does not, and produce an emotional involvement that helps students learn. Thus, while many administrators and educators rush to develop webbased remote learning sites, to leverage the economic advantages of one-tomany learning modalities, these sites deprive learners of the contextualization and embodiment inherent in brick-and-mortar learning institutions, and which are needed to support the activity of learning. Can these qualities be achieved in virtual learning environments? If so, how? These are some of the questions this talk will try to answer by presenting a virtual place-making methodology and its experimental implementation, intended to create a sense of place through contextualization and embodiment in virtual learning environments.

title Mastering Urban Network Intersection And Superimposition, in an Object-oriented Knowledge System Integrating Rules, Neurons and Processes
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Many networks cover the urban texture, either superimposed at a variable distance, or really intersecting, or even in interconnection. We briefly recall the HBDS model, working on persistent abstract data types associated to graphical representations and carrying algorithms expressing conditions to be verified and/or actions to be performed. HBDS is an integrated system too, including database, expert system dealing with fuzzy rules and facts, discrete simulation engine, and neural engine; it has a general purpose programming language. Any urban network is associated to a given prototype, according to the same scheme named prototype with more specific components. These prototypes allow to build the different thematic structures instantiations of the prototypes. All possible cases of arc intersection or "pseudo-intersection" (simple superimposition)or interconnection are obtained by, owing to new prototypes. Moreover, such (pseudo)-intersections are automatically recognized and processed without a human intervention, owing to classes ofconstraints and classes of rules. They deal with particular constraints concerning the location of some urban furniture, and rules concerning the way a cable or a pipe must follow according to thepre-existing other networks in a given area, the minimal distances, minimal or maximal depths, and some required equipments. Urban classes of (pseudo-)intersections inserted in the hyperciass"neuron", inheriting of neural features, may be used for automated learning of urban knowledge; owing to their "behavior", these neurons can communicate and perform actions on other components. Urban classes inserted in the hyperciass "process" may be used for building very large models simulating complex urban phenomenons, thus allowing a better understanding of the real phenomenons. As a conclusion, we emphasize the methodological aspects of object-oriented integration for an efficient processing of the urban context, based on prototyping and mixing rules, neurons and processes.

title Providing a Structured Method for Integrating Non-Speech Audio into Human-Computer Interfaces
source Heslington, York: University of York
summary This thesis provides a framework for integrating non-speech sound into human-computer interfaces. Previously there was no structured way of doing this, it was done in an ad hoc manner by individual designers. This led to ineffective uses of sound. In order to add sounds to improve usability two questions must be answered: What sounds should be used and where is it best to use them? With these answers a structured method for adding sound can be created. An investigation of earcons as a means of presenting information in sound was undertaken. A series of detailed experiments showed that earcons were effective, especially if musical timbres were used. Parallel earcons were also investigated (where two earcons are played simultaneously) and an experiment showed that they could increase sound presentation rates. From these results guidelines were drawn up for designers to use when creating usable earcons. These formed the first half of the structured method for integrating sound into interfaces. An informal analysis technique was designed to investigate interactions to identify situations where hidden information existed and where non-speech sound could be used to overcome the associated problems. Interactions were considered in terms of events, status and modes to find hidden information. This information was then categorised in terms of the feedback needed to present it. Several examples of the use of the technique were presented. This technique formed the second half of the structured method. The structured method was evaluated by testing sonically-enhanced scrollbars, buttons and windows. Experimental results showed that sound could improve usability by increasing performance, reducing time to recover from errors and reducing workload. There was also no increased annoyance due to the sound. Thus the structured method for integrating sound into interfaces was shown to be effective when applied to existing interface widgets.

title Virtual Worlds: No Interface to Design
source Cyberspace - First Steps, M.Benedikt ed, MIT Press
summary In a virtual world, we are inside an environment of pure information that we can see, hear, and touch. The technology itself is invisible, and carefully adapted to human activity so that we can behave naturally in this artificial world. We can create any imaginable environment and we can experience entirely new perspectives and capabilities within it. A virtual world can be informative, useful, and fun; it can also be boring and uncomfortable. The difference is in the design. The platform and the interactive devices we use, the software tools and the purpose of the environment are all elements in the design of virtual worlds. But the most important component in designing comfortable, functional worlds is the person inside them. Cyberspace technology couples the functions of the computer with human capabilities. This requires that we tailor the technology to people, and refine the fit to individuals. We then have customized interaction with personalized forms of information that can amplify our individual intelligence and broaden our experience. Designing virtual worlds is a challenging departure from traditional interface design. In the first section of this chapter I differentiate between paradigms for screen-based interface design and paradigms for creating virtual worlds. The engineer, the designer, and the participant co-create cyberspace. Each role carries its own set of goals and expectations, its own model of the technology's salient features. In the second section of the chapter I address these multiple perspectives, and how they interrelate in the cooperative design process. In conclusion, I consider broader design issues, including control, politics, and emergent phenomena in cyberspace.

title A Critique of Virtual Reality in the Architectural Design Process, R-94-3
source Human Interface Technology Laboratory, University of Washington, Seattle, USA, http://www.hitl.washington.edu/publications/r-94-3/: 23 May 2001
summary An addition to a building was designed using virtual reality (VR). The project was part of a design studio for graduate students of architecture. During the design process a detailed journal of activities was kept. In addition, the design implemented with VR was compared to designs implemented with more traditional methods. Both immersive and non-immersive VR simulations were attempted. Part of the rationale for exploring the use of VR in this manner was to develop insight into how VR techniques can be incorporated into the architectural design process, and to provide guidance for the implementers of future VR systems. This paper describes the role of VR in schematic design, through design development to presentation and evaluation. In addition, there are some comments on the effects of VR on detailed design. VR proved to be advantageous in several phases of the design. However, several shortcomings in both hardware and software became apparent. These are described, and a number of recommendations are provided.

title DesignSpace: A Manual Interaction Environment for Computer Aided Design DEMONSTRATIONS: Virtual Reality Multimedia
source Proceedings of ACM CHI'94 Conference on Human Factors in Computing Systems 1994 v.2 pp. 33-34
summary DesignSpace is a computer-aided-design (CAD) system that facilitates dexterous manipulation of mechanical design representations. The system consists of an interactive simulation programmed with a seamless extended model of the designer's physical environment and driven with continuous instrumentation of the designer's physical actions. The simulation displays consistent visual and aural images of the virtual environment without occluding the designer's sensation of the physical surroundings. Developed at Stanford University's Center for Design Research (CDR), DesignSpace serves as an experimental testbed for design theory and methodology research. DesignSpace includes significant contributions from recent CDR development projects: TalkingGlove, CutPlane, VirtualHand, TeleSign, and VirtualGrasp. The current DesignSpace prototype provides modeling facility for only crude conceptual design and assembly, but can network multiple systems to share a common virtual space and arbitrate the collaborative interaction. The DesignSpace prototype employs three head-tracked rear projection images, head-coupled binaural audio, hand instrumentation, and electromagnetic position tracking.

title A digital Procedure of Building Construction: A practical project

summary In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

summary Augmented Reality (AR) technologies are often perceived as the most impactful method to enhance the communication between the designer and the client during the iterative design process. However, the significance of designing the User Interface (UI) and the User Experience (UX) are often underestimated. To intercede, this research aims to employ new and existing techniques to develop UI's, and comparatively assess "the accuracy and completeness with which specified users can achieve specified goals in particular environments" (Stone, 2005) - a notion this research delineates as 'effectiveness'. Prompted by the work of key scholars, the developed UI's were assessed through the lens of existing UI evaluation techniques, including: Usability Heuristics (Nielsen, 1994) and Visual and Cognitive Heuristics (Zuk and Carpendale, 2006). In partnership with PTW Architects, characteristics such as the rapidity and complexity of interactions, in conjunction with the interface's simplicity and intuitiveness, were extracted from 15 trials underwent by architectural practitioners. The outcomes of this research highlights strategies for the effective development of user interface design for mobile augmented reality applications.

summary In 1986 the Faculty of Architecture was established in Maputo. It is financed by the Italian Ministry of Foreign Affairs and managed by a Scientific Council of the Faculty of Architecture of "Università La Sapienza" of Rome. The need to create human technical resources beeing able to work profesionally as soon as they finish their studies, made the teaching basis for lab exercises and design. The new architects (the first six students graduated in 1991), need to design and make very important decisions without any control by more experienced local technical institutions. The creation of a CAAD laboratory, and the teaching of information technologies and metodologies in architectural designing aimes to achieve a double goal: (-) to make the new architects able to manage on their own, because of the lack of qualified human resources, large quantity of data, and difficult design problems; (-) to make University, the most important scientific center in the country, an information exchange center between developped countries, and Moçambique.

summary Computer-aided-design (CAD) systems are now used to design all kinds of artifacts, from jet fighters to works of art. A major challenge in the design of a CAD system itself is the user interface (UI). Developing the UI to a CAD system raises myriad questions about input devices and techniques, display devices and techniques, and the details of the dialogue that relates the two. But these questions are ancillary to one central question: what is the fundamental nature of the interaction between human and computer in the design process supported by the CAD system? Is the design activity essentially manual, with the computer playing the role of passive tool, like a pen or paintbrush? Or is the computer augmenting the human designer by actively restricting available design choices, or by playing the role of critic or "improver"? Or maybe the interaction paradigm is one of "interactive evolution," in which the computer is responsible for generating design alternatives, with the human merely choosing among choices suggested by the machine. Or perhaps the computer performs the design process completely automatically, with a final acceptance check being the only human contribution? The panelists will describe these different paradigms for human-computer cooperation in a set of related CAD systems and prototypes and discuss the conditions under which each paradigm might be most useful.

summary What is the role of CAAD as a tool of architectural form creation ? We used to over-estimate the role of computer as significant factor of design process. In fact it serves only to produce technical documentation and to visualise designed buildings. We usually use CAAD to record ideas, not to create designs. We use it like more complex pencil. But it is unsuitable for conceptual design , with imperceptible influence on idea definition. Its practical usefulnes is limited. I would like to consider and find out reasons of that state, present some conclusions and ideas on computer aided architectural form creation. Many tools were invented to extend posibilities of human body or intellect. Microscop and telescop are extensions of human eye. Which organ is extended by computer (especially by CAAD)? CAAD with high developed function of visualising of the object beeing designed seems to be an extension of architect's imagination. It is beeing used to foresee visual efects, to check designed forms, to see something what we are not able to imagine. It performes the role of electronic modeler. Real model and virtual model - the medium of presentation is diferent but ways of using them are similar . Dislocation of place where we build model is not a big achievement, but potential possbilities of CAAD in modeling are almost unlimited (?). What are special features of CAAD as a modeling tool? First we have to consider what is indispensible when building a model: to embody idea. To do this we need space, substance and tools. In architectural design practice space is a real site with definite climate, neigbourhood, orientation. Substance that we shape is an archiectural form composed of many difrent elements: walls, windows, roof, entry, ... , proportions, rhythm, emotions, impresions... The tool is: our knowledge, imagination, talent, experience, norms, law and drawing equipment. Working with the computer, making virtual model, we have many of mentioned elements given in structure of CAAD program and interpreted by it. But many of them have different character. Making traditional dummy of building we operate on reality which is manually accessible. In case of computer model we operate on information. Space, substance and tool (- program) are informations, data. Human being is not an abstract data processor, but creature that lives non stop in close, direct, sensual contact with nature. By this contact with enviroment collects experiences. Computer can operate on digital data that is optionally selected and given by user, independent upon enviromental conditions. Usually architecture was created on basis of enviroment, climate, gravity. But these do not exist in CAAD programs or exist in the symbolic form. Character of these conditions is not obvious. We can watch demeanour of objects in gravity but it can be also antigravity. In theory of systems everything is considered as a part of biger system. In "virtual" reality (in computer space) we deal with accurences which are reduced to abstract level, free upon terms or connections. We work with our CAAD software using geometric space whithout any other principle.

(Mitchell 1990) This statement typifies a design education philosophy in which the concepts of space and form are separated and defined respectively as the negative and positive of the physical world, a world where solid objects exist and void-the mere absence of substance-is a surrounding atmospheric emptiness. Since the beginning of the nineteenth century, however, there has been an alternative concept of space as a continuum: that there is a continuously modified surface between the pressures of form and space in which the shape of the space in our lungs is directly connected to the shape of the space within which we exist. (Porter 1979). The nature of the task of representing architecture alters to reflect the state of architectural understanding at each period of time. The construction of architectural space and form represents a fundamental achievement of humans in their environment and has always involved effort and materials requiring careful planning, preparation, and forethought. In architecture there is a necessary conversion to that which is habitable, experiential, and functional from an abstraction in an entirely different medium. It is often an imperfect procedure that centers on the translation rather than the actual design. Design of the built environment is an art of distinctions within the continuum of space, for example: between solid and void, interior and exterior, light and dark, or warm and cold. It is concerned with the physical organization and articulation of space. The amount and shape of the void contained and generated by the building create the fabric and substance of the built environment. Architecture as a design discipline, therefore, can be considered as a creative expression of the coexistence of form and space on a human scale. As Frank Ching writes in Architecture: Form, Space, and Order, "These elements of form and space are the critical means of architecture. While the utilitarian concerns of function and use can be relatively short lived, and symbolic interpretations can vary from age to age, these primary elements of form and space comprise timeless and fundamental vocabulary of the architectural designer." (1979)

title Control of Parts: Identifying Patterns of Control in Production Chains
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary If we examine the stages of production of complex physical systems, we notice that parts change as they progress along a value chain. Parts are deformed, have parts removed, and are assembled and disassembled, in various sequences. In such processes, production operations (milling, cutting, aligning, attaching, and so on) are of particular interest, as are the sequences of production, since some operations and sequences have been found to be more efficient than others, lead to fewer mistakes and produce higher quality results. Research continues to be produced seeking to optimize production operations, sequences and product quality. The production operations we can observe in the making of artifacts are also of interest because they are by definition the result of action taken by certain agents. Parts are changed or controlled by human beings, employing their own hands or sophisticated machines. Today, we are used to making a distinction among agents involved in production: some agents specify what is to be made, and others make what is specified. One agent can do both, but specialization and division of labour has presented us with this distinction. This is now conventional, aside from whether it is "good" or not. The distinction is the basis for the interest in "concurrent design and production of products", the renewed focus on distribution and coordination of work in teams, and the related interest in understanding the dynamics of building systems in terms of the agents who control them. This paper focuses on the place certain kinds of agents take in complex production flows. Since production of parts is both a technical and a social enterprise, we will discover, when we look closely, complex webs of interactions which can be mapped, showing how agents relate to each other through the parts with which they are concerned. In examining the class of agents who control parts, we can see two patterns of control, termed DISPERSED PATTERNS and OVERLAPPING PATTERNS. These become palpable in a graphic diagramming tool, which is demonstrated in what follows. These diagrams also provide a means to consider the agents whose role is to specify what is to be made. The paper includes notes related studies in other fields.Finally, the paper suggests how this perspective can be useful, and several research topics based on it are sketched.

title Image and Brain: The Resolution of the Imagery Debate
source The MIT Press, Cambridge, p. 1
summary Kosslyn (psychology, Harvard U.) presents a 20-year research program on the nature of high-level vision and mental imagery--offering his research as a definitive resolution of the long-standing "imagery debate," which centers on the nature of the internal representation of visual mental imagery. He combines insights and empirical results from computer vision, neurobiology, and cognitive science to develop a general theory of visual mental imagery, its relation to visual perception, and its implementation in the human brain.

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.

title Some Phenomena of seeing shapes in design
source Design Studies, v 16, n 3, pp. 367-385
summary This paper is a look at some of the pyschological results that suggest how shape emergence manifest itself in the human mind. The first interesting result goes back to top down expectation guiding recognition. Some experimental suggest that it is easier (quicker) to recognize shapes which we have some alternate mental familiarity. (I.E. verbal, structural descriptions). So if we can easily say a shape then we can easily discern it as an emergent shape. The paper then goes on to discuss the definition of emergent subshapes and gives various authors definitions of what makes up and emergent shape. One interesting classification is the difference between explicit and implicit emergent shapes made by Mitchell. This difference amounts to a fine line between imagination and emergence. The results of an experiment between experienced and in-experienced designers is discussed. The results suggest that experienced designers are able to find more emergent shape than non experienced designers. From these results and from the opinions of others, the author goes on to specify 3 phenomena related to emergent recognition. The first is as above that it is easier to see shapes with which we are familiar. Second from this, the harder shapes are found after the initial period. Third, from the first two, time is required to find more subshapes. The author then searches for an explanation of this phenomena. He suggests that the underlying cause is related to an experience person having a lower threshold of what it is to be a member of a shape. When seeing an L shape the experienced design is likely to consider it also a square, because his requirement for the set of features which must be present for some object to be a considered a square is a smaller set than the inexperienced. While the author suggests that this is a phenomena it is actually an hypothesis. An alternate hypothesis may be that top down inhibitions effect the bottom up performance of the inexperienced design more because of different representation.

title Applying Visual Design: Trade Secrets for Elegant Interfaces TUTORIALS
source Proceedings of ACM CHI'94 Conference on Human Factors in Computing Systems 1994 v.2 pp. 353-354
summary This tutorial describes a number of fundamental techniques applied routinely in communication-oriented visual design. The orientation, process, training, and culture of the visual design disciplines (graphic design, industrial design, interior design, architecture) are essential components of effective interface design. Unfortunately, few software developers or human factors engineers receive any training in these disciplines. This tutorial describes important design rules and techniques internalized by every visual designer through coursework and studio experience. While mastery will indeed require extended practice, the techniques we describe are not difficult to understand and can be immediately applied to real-world problems. We draw our background, training, and influence from the rational, functional, information oriented perspective of the Modernist design ethic. Because all graphical user interfaces are communication systems, we believe their design should reflect these same values. Our tutorial is organized not along the traditional subdisciplines of color, typography, or ideation, but along the problems of graphical interface design as experienced in commercial software development. We describe basic design principles (the what and why), common errors, and practical techniques (the how) for each of the six major areas outlined below. (1) Elegance and Simplicity (2) Scale, Contrast and Proportion (3) Organization and Visual Structure (4) Module and Programme (5) Image and Representation (6) So What About Style?
