title	Constructing Three-Dimensional Mental Models from Two-Dimensional Displays
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	In the present study we adopted the tasks and the experimental procedures used in a recent series of study by Cooper (1990, 1991) for the purpose of examining how we utilized two-dimensional information in a line-drawing of visual objects to construct the corresponding three-dimensional mental structure represented by the 2-D displays. We expected that the stimulus materials we used avoided some of the problems that Cooper's stimuli had, and with that we examined the effect of complexity on the process of constructing 3-D models from 2-D displays. Such a manipulation helps to elucidate the difficulties of solving problems that require spatial abilities. We also investigated whether or not providing information representing an object viewed from different standpoints would affect the construction of the object's 3-D model. Some researchers have argued that 3-D models, once constructed, should be viewer-independent or viewpoint-invariant, while others have suggested that 3-D models are affected by the viewpoint of observation. Data pertinent to this issue are presented and discussed.

title	Image Collections in the Design Studio

summary	No matter what the medium, architects are constantly using images in all aspects of design thinking. Whether it is the perception of the environment, an image in the mind's eye, an abstract drawing or a photographic record, designers use images to conceive of, and manipulate their design ideas. Managing these image collections occurs at a variety of levels in the creative process and is dependent on the type of image that is called upon for reference. The most basic example would be the image collection residing in the mind's memory which is a result of the designer’s world experiences and the relative impressiveness of each experience. Clearly, personal memory plays a significant role in the use of imagery in design, but it is unreliable and can be abstracted in uncontrollable ways. The sketchbook and later photographic collections of the grand tour were the beginnings of efforts to manage and utilize image collections as an aid to drawing and thinking about design. Now the capacity to use electronic means of creating, altering, storing, and retrieving images will enable designers to effectively use large image collections in ways that have not been possible before. This paper describes current work at the School of Architecture at Washington University in a graduate design studio. The students use a powerful 3D modeling CAD system (HOKDraw) to design and present their studio projects. In addition, we are experimenting with an image storage and retrieval system which is directly linked to the CAD model through a relational database (INGRES). Access to the database and images is instantly available through the command language and graphic display. The CAD model in effect becomes a 3D menu to an extensive image database stored on an optical memory disc recorder. Several collections are available to the studio members: the library's slide collection which relates to the studio project, specific photographs and drawings of the project site, and personal image collections stored by individuals for their own reference. The commonly accessible images are basically background material and images collected by the students to document the site, urban context and building typology. The personal images collections are any images (drawings, photographs, published images, CAD images) created or collected by the students for purposes of informing their design thinking. This work relates to the use of precedents and typology in architecture as a point of departure as well as in development of design ideas.

title	Linking perception and graphics: modeling with dynamic constraints
source	Barlow, H., Blackemore, C. and Weston-Smith, M. (eds), Images and understanding, Cambridge University Press, Cambridge, pp. 213-226
summary	Images and Understanding Thoughts about Images: Ideas about Understanding How do you paint a picture of infinity? How do you dance about death? How do you draw a diagram explaining entropy? Images and Understanding explores the human problem of moving facts and ideas from one mind to another - the problems of how we see and communicate using images expressed in pictures, diagrams, words, music and dance. For artists as well as scientists discussion of this topic is timely; electronic and computing technology is expanding the means of generating and communicating images, while physiology and psychology are revealing the neural mechanisms of coding, perceiving and understanding them. The book is divided into six sections, each with an explanatory introduction followed by comprehensively illustrated contributions from internationally distinguished figures from fields as diverse as art history, choreography, psychology, computer science, and philosophy. Images and Understanding is unique in viewing the problems of imagery through the eyes of both science and art; it gives new insight into images and new ideas about understanding. Contributors

title	A Quantitative Method to Compare the Impact of Design Mediums on the Architectural Ideation Process.
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 539-556.
summary	If we compare the architectural design process to a black box system, we can assume that we now know quite well both inputs and outputs of the system. Indeed, everything about the early project either feasibility studies, programming, context integration, site analysis (urban, rural or natural), as well as the integration of participants in a collaborative process can all be considered to initiate and sustain the architectural design and ideation process. Similarly, outputs from that process are also, and to some extent, well known and identifiable. We are referring here, among others, to the project representations or even to the concrete building construction and its post-evaluation. But what about the black box itself that produces the ideation. This is the question that attempts to answer the research. Currently, very few research works linger to identify how the human brain accomplishes those tasks; how to identify the cognitive functions that are playing this role; to what extent they operate and complement each other, and among other things, whether there possibly a chain of causality between these functions. Therefore, this study proposes to define a model that reflects the activity of the black box based on the cognitive activity of the human brain. From an extensive literature review, two cognitive functions have been identified and are investigated to account for some of the complex cognitive activity that occurs during a design process, namely the mental workload and mental imagery. These two variables are measured quantitatively in the context of real design task. Essentially, the mental load is measured using a Bakan's test and the mental imagery with eyes tracking. The statistical software G-Power was used to identify the necessary subject number to obtain for significant variance and correlation result analysis. Thus, in the context of an exploratory research, to ensure effective sample of 0.25 and a statistical power of 0.80, 32 participants are needed. All these participants are students from 3rd, 4th or 5th grade in architecture. They are also very familiar with the architectural design process and the design mediums used, i.e., analog model, freehand drawing and CAD software, SketchUp. In three experimental sessions, participants were asked to design three different projects, namely, a bus shelter, a recycling station and a public toilet. These projects were selected and defined for their complexity similarity, taking into account the available time of 22 minutes, using all three mediums of design, and this in a randomly manner to avoid the order effect. To analyze the two cognitive functions (mental load and mental imagery), two instruments are used. Mental imagery is measured using eye movement tracking with monitoring and quantitative analysis of scan paths and the resulting number and duration of participant eye fixations (Johansson et al, 2005). The mental workload is measured using the performance of a modality hearing secondary task inspired by Bakan'sworks (Bakan et al.; 1963). Each of these three experimental sessions, lasting 90 minutes, was composed of two phases: 1. After calibrating the glasses for eye movement, the subject had to exercise freely for 3 minutes while wearing the glasses and headphones (Bakan task) to get use to the wearing hardware. Then, after reading the guidelines and criteria for the design project (¬± 5 minutes), he had 22 minutes to execute the design task on a drawing table allowing an upright posture. Once the task is completed, the subject had to take the NASA TLX Test, on the assessment of mental load (¬± 5 minutes) and a written post-experimental questionnaire on his impressions of the experiment (¬± 10 minutes). 2. After a break of 5-10 minutes, the participant answered a psychometric test, which is different for each session. These tests (¬± 20 minutes) are administered in the same order to each participant. Thus, in the first experimental session, the subject had to take the psychometric test from Ekstrom et al. (1978), on spatial performance (Factor-Referenced Cognitive Tests Kit). During the second session, the cognitive style is evaluated using Oltman's test (1971). Finally, in the third and final session, participant creativity is evaluated using Delis-Kaplan test (D-KEFS), Delis et al. (2001). Thus, this study will present the first results of quantitative measures to establish and validate the proposed model. Furthermore, the paper will also discuss the relevance of the proposed approach, considering that currently teaching of ideation in ours schools of architecture in North America is essentially done in a holistic manner through the architectural project.

summary	Architects rely on the graphic language of words and art to bridge intention and design, just as it has always been. Yet, passing an idea or concept from mental imagery to design practice through 2D, 3D, and 4D design filters is especially challenging in BIM technology. Severe limitations hinder or even preclude BIMs use in certain complex design tasks, as identified in the Anti-Box, "The anti-box celebrates the death of the ninety-degree angle- in fact, every angle." (de Graaf 2017). Compatibility and constraints determine the most appropriate uses of BIM software, from designing mundane shopping mall developments to complex architectural engineering feats that stagger the imagination. BIM's main benefit is in the middle when it is creatively employed by professional architects in multi-discipline collaborations, well versed in symbolic representation, of designs conceived of multivalent design factors: narrative, form, function, multi-sensory access, materiality, space, and environment.

title	What Is Intention Structure? - Represent Invisible Information of Spatial Depicts
doi	https://doi.org/10.52842/conf.caadria.2004.275
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. 275-286
summary	The significant problem of this paper is how we convey spatial information to represent concrete meaning of mental imagery. For replying the above problem, we are developing a spatial information structure called "Intention Structure". Intention structure is used to represent some spatial experience of a particular person and awareness of the aura into some spatial depicts at that physical place. The meaning of “intention” is implied into a sequential relation when a navigator moves and gazes something in a place. This sequential relation can be described into two ways of spatial representation: one is the action of human body including “moving the body” and “moving the head”; another is converting the visual information into spatial memories through the behavior of gaze, including “the sight focus” and “the snapshot glance”. Otherwise, we also consider the limitation of topology at that physical place. Based on the above ideas, we use XML technologies in Java language to represent spatial data of intention structure for the describable usages of invisible information. we implemented this idea on a project of spatial analysis with Taiwanese traditional garden, the Lin family garden in Banciao, Taipei County, Taiwan.

title	AI-Bewitched Architecture of Hansel and Gretel: Food-to-Architecture in 2D & 3D with GANs and Diffusion Models
doi	https://doi.org/10.52842/conf.caadria.2023.1.009

summary	Architects such as Le Corbusier, Frank Gehry, Aldo Rossi, and Greg Lynn have implicitly turned culinary formalism into architectural formalism during their careers. How might AI assist in a similar act of bisociation (or conceptual blending)? The paper is the first to explore this food2architecture bisociation explicitly, and specifically with generative adversarial networks (GANs) such as CycleGAN and VQGAN-CLIP, and diffusion models such as OpenAI’s DALL-E 2, Midjourney and DreamFusion (using Stable Diffusion). Instead of using textual input prompts to generate images of architecture only with the discipline’s own vocabulary, the research merges them with the vocabulary of food, thus exploiting their potential in blending their respective conceptual and formal characteristics. While these diffusion models have recently been used by the general public to generate 2D imagery posts on various social media platforms, no existing work has conducted a detailed and systematic analysis on their exclusive capacity in bisociating food and architecture. Imagery outputs generated during two workshops involving 150 designers and non-designers are included here as illustrations. Beginning and ending the paper with the all-familiar fairy tale of the gingerbread house, the research explores the creative design bisociative affordance of today's text-to-image and text-to-3D models by turning culinary inputs into architectural outputs -- envisioning an explicitly computational version of the implicit 'food2architecture' mental models plausibly used by some of the most creative architects.

title	Ideas - The Embodiment of Ideas, and Drawing: An Experimental Investigation of Inventing
source	J. S. Gero, B. Tversky and T. Purcell (eds), 2001, Visual and Spatial Reasoning in Design, II - Key Centre of Design Computing and Cognition, University of Sydney, Australia
summary	The term visual reasoning, in cognitive psychology, oftenrefers to the use of visual spatial relations in making inferences aboutcorresponding conceptual relations. The conclusion is that external visualrepresentations have special properties, which can aid reasoning abouthigher order abstract concepts. The design literature is more specific andoften sees visual reasoning as synonymous with drawing, and considersthis a core activity in resolving design problems. The research to bereported examined visual reasoning and design, by investigating the rolethat drawing plays in the practicality and creativity of inventions. Themost striking finding was that using only mental imagery produced morecreative and practical inventions than the use of drawing and that this wasdependant on the area of expertise of the participants. This appears to runcounter to the views found in both the visual reasoning and designliterature regarding the effectiveness of visual representations anddrawing. This has implications for our understanding of both the visualreasoning and design thinking processes.

title	Geometric Relations as a Framework For Design Conceptualization
source	Harvard University, Graduate School of Design
summary	This study introduces geometric relations as a framework for design conceptualiza-tion-its key premise is that nothing is more fundamental in design than formation and discovery of relationships. The study attempts to establish a formal model for the development of a dynamic computer based graphic environment for design conceptualization that can recognize, record and maintain geometric design relations, merge "depictive" and "propositional", explicit and implicit in design, and provide a qualitatively different way to explore shape, dimension, and geometric organization. The study presents an approach to this task of formalization, and explores some of the fundamental issues pertinent to the subject, such as computability and applicability to the task of designing.Specifically, the study explores a relational description of shapes based on the concept of regulating or construction lines as an explicit formulation of a strategy to form generation and creative discovery, and proposes a lexicon of geometric relations to serve as a basis for composition. It hypothesizes that the construction lines can become much more useful and interesting when they are used not just as a rigid skeleton, but to regulate the behavior of a drawing and to maintain its essential structure as its parts are manipulated. As a consequence, designers could structure the behavior of the object being designed under future transformations; drawings could become seman-tically charged and could be manipulated in a semantically sophisticated fashion.The first chapter places the issue in the broader context by arguing that designers form implicit relational models of their designs. This contention is supported by introducing some of the relevant literature on mental imagery. Second chapter introduces design relations and in particular geometric relations, as a focal point of this study. A dynamic computer -based graphic context for design conceptualization is presented and evalu-ated in the next two chapters and conclusions are drawn. In the third chapter, the model's computability is demonstrated and evaluated through ReDRAW, a limited implementation of a relations based graphic system. In the fourth chapter, the model's applicability in design conceptualization is discussed and supported by examples.

source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 420-427
summary	This paper addresses the concept of spatial diagnosis as a methodology for architects to analyze and evaluate the quality of existing spaces periodically and improve them with the use of digital media. Initially the methodology researches the physical characteristics of the examined space, which are investigated both historically and empirically, as well as people’s mental imagery of it, which is examined through cognitive mapping techniques. The research findings are used as a mapping device for the application of the digital media ‘treatment.’ Selected intelligent systems form a digital, immaterial layer upon the existing spatial elements increasing the quality of space and consequently improving people’s experience in it. The goal of this project, which focuses solely on public spaces for the extent of this research, is twofold. On a design level, it proposes a way to increase the quality of space as well as its potential to communicate with people through a synergic, adaptive approach. On a research level, it seeks to bring together three diverse but not distant disciplines, those of architecture, cognitive psychology and information technology.

title	Developing 3-D Spatial Visualization Skills
source	Engineering Design Graphics Journal, vol. 63, no. 2 (Spring): 21-32
summary	This article brings up the point that 3-D spatial visualization skills are vital to graphics education. Instructors of graphics education, even though they have highly advanced spatial skills, rarely have the proper training on what spatial skills are or how the development of spatial skills takes place. As a result one must try to have a better understanding of spatial abilities. There are many interpretations as to what spatial skills really are and there is in therefore no one universal definition. As a way to better understand spatial abilities, Maier places them into five categories. The categories are spatial perception, spatial visualization, mental rotations, spatial rotations, and spatial orientation. These categories are vast. As a result of their vastness many of the categories overlap. Another step towards better understanding spatial skills involves differentiating how spatial skills are used while completing a task. Tartre makes a classification for how spatial skills are used while performing a task. The spatial skills are either used as spatial visualization that involves mentally moving the object, or as spatial orientation, which involves mentally moving the object. If the task involves spatial visualization then mental rotation can take place, which involves the entire object, or mental transformation can occur, which only involves part of an object. Visual thinking is a way to understand spatial skills. McKim offers the viewpoint that visual thinking occurs by three kinds of imagery. They are what one sees, what one can imagine, and what one can draw. All of these images interact with one another. Spatial skills are developed primarily in three different stages. This can be see be Piaget's theory on development. In the first stage, two dimensional, topological, skills are acquired. In the second stage, an understanding of 3-D objects, projective skills, from different viewpoints is achieved. Finally in the third stage, there is an understanding of area, volume, distance, translation, rotation and reflection, which is combined with projective skills. Spatial skills are evaluated in a variety of ways. There are tests that assess a person's projective skill level. Examples of these would be the Mental Cutting Test and the Differential Aptitude Test: Spatial Relation. Other tests assess mental rotation. Examples of mental rotation tests are the Purdue Spatial Visualization Test and the Mental Rotation Test. Results of these evaluations show mixed results as to whether there are gender differences in spatial skills. In order to enhance spatial skills, one must not only work with 3-D images, but they must also use concrete models and sketching. Overall I thought this article was very informative. It presented the information in a clear and concise manner. I summarized the information that I thought was especially useful for this class. The article really made me think how important it is not only to have spatial skills, but also to have an understanding of them.

title	The cognitive basis of emergence: implications for design support
source	Design Studies, Vol. 17 No. 4, 451-463
summary	Emergent shapes play a significant role in the creative design process. Designers frequently visualize emergent shapes and structure their understanding of the design and their reasoning about it in terms of emergent entities and relations. In design research, effort has concentrated on developing computational models capable of representing emergent shapes. Much less attention has been paid to the cognitive processes that give rise to emergence. In cognitive science, however, emergence has been the subject of empirical study. It is suggested that both the study of perception and that of mental imagery can contribute to understanding the cognitive psychological basis of emergence and the nature of emergent shapes that arise. Relevant cognitive science research findings are reviewed in this paper. Based on these findings two main classes of emergence processes are developed. Their implications for the development of user-interactive computational models of emergent shapes are then discussed.

summary	The experience of artificial objects in the virtual environment and the illusion of being there is a primary affordance of the virtual reality (VR) environment. The conviction of being located in a mediated environment is referred to as spatial presence. Although some studies investigate the relationship between VR and spatial intelligence, how users build a spatial presence in VR game environments remains ambiguous. Regarding that, this study tries to elaborate on the spatial presence experience construction and its characteristics in virtual reality (VR) puzzle-solving games by revealing the relationships between game mechanics and spatial presence notion. In this study, the presence-spatial performance relations are initially investigated based on previous works and analyzed in terms of spatial definition. Suppose the VR task performance depends on spatial abilities, people with higher spatial ability finish tasks faster, and their spatial presence score will be higher than people with lower spatial ability. A VR game called Golden Gate VR will be used as a case study to test and elaborate on the hypothesis above. This ongoing study has five steps: (1) Development of the game environment, (2) pre-psychometric assessment for visuo-spatial ability (Pre-Test), (3) Experience of the VR Game, (4) Evaluation of the experiences, (5) Re-development of the game environment. Experiences of the players’ will be evaluated in terms of Mental Imagery, Mental Rotation and Spatial Orientation regarding Spatial Presence Experience Scale (SPES). The first four steps will be elaborated on in this paper.

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.

summary	The computer offers enormous potential both in and out of the classroom that is realized only in limited ways through the applications available to us today. In the early days of the computer it was generally argued that it would replace the architect. When this idea became obsolete, the prevailing opinion of proponents and opponents alike shifted to the notion of the computer as merely adding to present design capabilities. This idea is so ingrained in our thinking that we still speak of "aiding" design with computers. It is clear to those who grasp the real potential of this still new technology - as in the case of many other major technological innovations - that it continues to change the way we design, rather than to merely augment or replace human designers. In the classroom the computer has the potential to radically change three fundamental ingredients: student, instruction, and instructor. It is obvious that changes of this kind spell out a commensurate change in design pedagogy. If the computer is going to be more than a passive instrument in the design studio, then design pedagogy will have to be changed, fundamentally. While the practice of computing in the studio continues to be a significant I aspect of architectural education, articulation of viable pedagogy for use in the design studio is truly rare. In this paper the question of pedagogy in the CAD studio will be considered first. Then one particular design studio taught during Fall 1988 at Carnegie Mellon University will be presented. Finally, we shall return to issues of change in the student, instruction, and instructor, as highlighted by this particular experience.

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	A Procedural Model for Integrating Physical and Cyberspaces in Architecture
source	Doctoral dissertation, University of Plymouth, Plymouth, U.K
summary	This dissertation articulates opportunities offered by architectural computation, in particular the digital simulation of space known as virtual reality (VR) and its networked, social variant cyberspace. Research suggests that environments that hybridize technologies call for a conception of space as information, i.e. space is both a product of and tool for cognition. The thesis proposes a model whereby architecture can employ this concept of space in creating hybrids that integrate physical and cyberspaces.The dissertation presents important developments in architectural computation that disclose concepts and values that contrast with orthodox practice. Virtual reality and cyberspace, the foci of this inquiry, are seen to embody the more problematic aspects of these developments. They also raise a question of redundancy: If a simulation is good enough, do we still need to build? This question, raised early in the 1990's, is explored through a thought experiment - the Library Paradox - which is assessed and critiqued for its idealistic premises. Still, as technology matures and simulations become more realistic the challenge posed by VR/cyberspace to architecture only becomes more pressing. If the case for virtual idealism seems only to be strengthened by technological and cultural trends, it would seem that a virtual architecture should have been well established in the decade since its introduction.Yet a history of the virtual idealist argument discloses the many difficulties faced by virtual architects. These include differences between idealist and professional practitioners, the failure of technology to achieve its proponents' claims, and confusion over the meaning of virtual architecture among both architects and clients. However, the dissertation also cites the success of virtual architecture in other fields - Human Computer Interface design, digital games, and Computer Supported Collaborative Work - and notes that their adoption of space derives from practice within each discipline. It then proposes that the matter of VR/cyberspace be addressed from within the practice of architecture, a strategy meant to balance the theoretical/academic inclination of previous efforts in this field.The dissertation pursues an assessment that reveals latent, accepted virtualities in design methodologies, instrumentation, and the notations of architectural practices. Of special importance is a spatial database that now pervades the design and construction processes. The unity of this database, effectively a project's cyberspace, and its material counterpart is the subject of the remainder of the dissertation. Such compositions of physical and cyberspaces are herein called cybrids. The dissertation examines current technologies that cybridize architecture and information technology, and proposes their integration within cybrid wholes. The concept of cybrids is articulated in seven principles that are applied in a case study for the design for the Planetary Collegium. The project is presented and critiqued on the basis of these seven principles. The dissertation concludes with a discussion of possible effects of cybrids upon architecture and contemporary culture.
