summary	This paper presents a kind of co-existence relationship: companying physical space with virtual space with a case study. The fundamental approach is to investigate the interactive relationship between navigators and information in virtual space, including collecting, interpreting, integrating, and communicating. Based on these relationships, we propose an information structure, which elaborates the information of our co-existence representation. The infrastructure composed with two processes of data representation based on an individual spatial structure is tested in representing eleven historical significant civic building in Taiwan.

summary	By exploring interactions between users and information, this paper intends to propose a co-existence framework for companying physical space with virtual space. Based on this framework, we implement an information structure for users to interact with information space interactively, which includes information nodes, hyperlinks and interplays through i-Room system (Chang and Lai, 2003). Furthermore, the information structure of representation is also tested and reevaluated in representing ten historical significant civic buildings in Taiwan.

title	An empirical approach to the experience of architectural space in VR - Exploring relations between features and affective appraisals of rectangular interiors
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 17-24

summary	While it is well known that the built environment influences our emotional state, it is often difficult to attribute these experiences to particular properties. In fact, a systematic investigation of the relation between physical structure and emotional experience of architecture has not yet been done. Now virtual reality simulations facilitate a completely controlled variation of spatial properties and thus allow to empirically evaluate architectural hypothesises. The aim of the presented study was to investigate which factors from a component-based description of rooms significantly correlate with cardinal dimensions of experience. In a perceptual experiment experiental qualities of 16 virtual vacant rectangular interiors were rated in eight principal categories by 16 participants using the semantic differential scaling technique. The scenes were generated by a custom made graphics tool that also automatically generated the component-based scene descriptions. The data analysis revealed several interesting correlations between scene features and rated experience: For example, a preference for ratios near to the golden section could be observed for spatial proportions, which are not directly perceivable. Altogether, a set of five independent factors (openness, two room proportions, room area and balustradeheight) appeared to be effective for widely describing the observed variance of the averaged attributed experiental qualities. Our combination of realistic virtual reality simulations and psychophysical data raising methods proved to be effective for basic architectural research. It allowed us to demonstrate quantitative relations between physical properties from a component-based description of architectural space and its emotional experience.

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.

title	Towards Comprehensive Space: A context for the programming/design of cybrids
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 161-171

summary	Cybrids have been presented as mixed realities: spatial, architectural compositions comprised of physical and cyberspaces (Anders 1997). In order to create a rigorous approach to the design of architectural cybrids, this paper offers a model for programming their spaces. Other than accepting cyberspaces as part of architecture’s domain, this approach is not radical. Indeed, many parts of program development resemble those of conventional practice. However, the proposition that cyberspaces should be integrated with material structures requires that their relationship be developed from the outset of a project. Hence, this paper provides a method for their integration from the project’s earliest stages, the establishment of its program. This study for an actual project, the Planetary Collegium, describes a distributed campus comprising buildings and cyberspaces in various locales across the globe. The programming for these cybrids merges them within a comprehensive space consisting not only of the physical and cyberspaces, but also in the cognitive spaces of its designers and users.

summary	The cyberspace upon physical space forms a new spatial structure to increase the influence on the urban fabric and the concept of space in architecture. Today, digital cities are being developed all over the world. By using a city metaphor, digital cities integrate urban information and create public spaces. However, human how to entry into the new emerging digital cities, to percept themselves in around cities, and then taking shape the recognition of digital city forms? How do digital cities directly connect to physical cities and become an imaginable city? Therefore, we argue that a new spatial analysis theory must be established for digital city, comparing with theories of spatial cognition, to find the explicitly spatial structures and relations in digital city upon physical city. This paper studied by the viewpoint of cognition in order to propose a prototype of metaphor of digital city.

title	A Body-Surrounding Study In Physical, Virtual and Mental Spaces

doi	https://doi.org/10.52842/conf.caadria.2003.343
summary	With the flourishing of architectural creation via all kinds of media, a comparison among physical, virtual and mental space becomes a fevered issue about spatiality due to the similar sense of space. This study reveals that even if the spaces constructed with distinct essence, a body-surrounding relation is an efficient way to formalize the problems of spatiality and relativity among three typical spaces. The sense of space and relative position reasoning were depicted with the Space-Transforming Test and the SpaceComprehending Test as a new concept about spatiality in general.

title	Automatic production of paths within audiovisual “narrative space” by making use of genetic algorithms
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 458-461
doi	https://doi.org/10.52842/conf.ecaade.2006.458
summary	This paper documents the theoretical aspect of a research project that deals with the application of an artificial life (AL) approach to engraving coherent paths within the narrative space of video fragments. These paths, which are constituted by the succession of short video segments, represent the best way to juxtapose isolated elements in the overall narrative landscape. In this case the notion of space is being used in a metaphorical way. Once this has been clarified, the concept of “narrative space” is used as a metaphorical representation of a database comprising all the fragmented/autonomous narrations that are being used. Therefore, the creation of an “intelligent” system that will be able to automatically create cinematographic narration is being examined. This project in particular investigates the possibility and the consequences of producing an autonomous cinematographic narration system, in which meaning results from a kind of hypermontage (Hakola, http://www.kromaproductions.net/HYPERMONTAGE.htm: Jan 2003) conditioned by genetic algorithms. A different type of spatial experience emerges when the video fragments used are automatically “put together” by the system. Video as a medium could be considered as representing crystallized shortcuts within physical reality. Since video fragments constitute the database, different elements of constructed space are parts of the same ensemble. From the composition of such fragments, there emerge new paths within the same spatial context and certain spatial experiences are formulated which are different from the ones experienced by actors during the shootings.

summary	In Taiwan, it is a common phenomenon that landscape, urban spaces, and buildings are not considered as a whole by governments at all levels and private clients. More terribly, the government has never proposed any urban statement for the future. The Minister strongly therefore proposes this statement: 2050 vision Taiwan, aim to design the public spaces for the life of Taiwan in the year 2050. The Council for Culture Affairs plans to spend two years to cover 100 locations and invite 20 design teams to provide new vision of the places. Our design team, AleppoZONE first conducts the initial stage of this project that includes three areas of Taiwan: Taipei as the capital of Taiwan is expected to become a better place reflecting new and old space combination. Hsinchu is planned to explore the prototype for a digital city where digital technology is wellinstalled in the city plaza and public buildings. In the island of Pen-Hu, the ecology and high-tech transportation are equally considered to shape Pen-Hu as an island with nature. In the process, design team successfully synthesizes digital models and dynamic films into virtual and physical coexisting environmental animations by using multiple digital media in realizing the 2050 vision cities. The aim of this research is to give a throughout introduction of this project.

summary	Computers, the new digital media, liberate the duality of concepts of space in human civilization. The construction and simulation powers of digital media trigger all kinds of unlimited imagination. The new space of this kind may be called digital space or virtual space. This new space is between mental and physical spaces because it provides designers with not only unlimited imaginality of mental space but also live-inside perception of physical space. A new concept of space of mankind is thus generated.

source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 165-168
doi	https://doi.org/10.52842/conf.ecaade.2003.165
summary	The paper reports on a research program to define the issues and strategies involved in the design of virtual architecture. Issues and categories of virtual architecture are identified and classified. An approach to the design of virtual place is derived from a large body of emerging literature as well as from the analysis of case-studies. We demonstrate and discuss how paradigms of physical design may be applied to support the needs of design for cyber-place. We attempt to define intrinsically digital possibilities for interface design that are not based upon a direct analogy to physical space. The findings in the form of alternative development possibilities and design guidelines may provide a guide to the field of virtual architecture, to its definition, design issues, and potential strategies.

summary	In this paper, we describe the research we undertake to investigate the perception and comprehension of spatial volumes within immersive, non-immersive virtual environments and physical models and their translation to a tangible representation. We set up two related design experiments to investigate the outcome of creation, interpretation and communication of architectural design. One, being the analysis of a cubic structure, based on three-dimensional (3D) interlocking volumes and spaces; and the other, being the design of a 3D-maze together with text -based communication. Collaboratively participants create, assess and analyse spatial relationships of volumes and spaces of a 3D maze structure or construct models of these spaces. The objective of our study is to identify how designers perceive space in Virtual Environments (VE) and communicate design ideas by using VE versa conventional methods of two-dimensional depictions such as paper and pen or 3D representations such as physical models. We investigate issues of quality, accuracy, understanding, communicating and rebuilding of designed or experienced architectural compositions.

title	A NEW APPROACH TO THE INTERACTIVE RESOLUTION OF CONFIGURATION PROBLEMS IN VIRTUAL ENVIRONMENTS
source	3rd International Symposium on Smart Graphics, Heidelberg, Germany, 2-4, July 2003. http://www.smartgraphics.org/ . Proceedings published by Springer: Lectures notes in Artificial Intelligence.
summary	Intelligent Virtual Environments integrate AI techniques with 3D real-time environments. As such, they can support interactive problem solving, provided the underlying AI techniques can produce solutions within a time frame matching that of user interaction. In this paper, we describe an intelligent virtual environment based on Constraint Logic Programming (CLP), integrated in a real-time 3D graphic environment. We have developed an event-based ap-proach through which user interaction can be converted in real-time into appro-priate solver queries which are then translated back into automatic reconfigura-tions of the Virtual Environment (VE). Additionally, this framework supports the interactive exploration of the solution space in which alternative solutions (configurations) can be found. We demonstrate the system behaviour on a con-figuration example. This example illustrates how solutions can be interactively refined by the user through direct manipulation of objects in the VE and how the interactive search of alternative solutions in the VE is supported by these type of systems.

doi	https://doi.org/10.52842/conf.acadia.2003.289
summary	This paper presents ways in which cybrids depend for their technology upon three existing models of architectural hybrid: display space, environmental computing, and augmented/mixed reality. Cybrids bring these techniques together into a synergistic whole that depends as much on the observer for its consistency as it does on its comprising technologies. This synergy is a product of corroborative behavior between different modes, which provide cybrid users with a coherent social/spatial experience. The paper notes cybrids’ similarity to theater, not only for their technological dependency, but also for the tacit yet vital role of the observer in their effect.

doi	https://doi.org/10.52842/conf.ecaade.2003.587
summary	In this paper the possibilities of using the computers at course of architectural compositions are considered. As the start point of the new teaching method of architectural composition we used the course of tradition architectural composition, elaborated at our Faculty. The course of Digital Architectural Composition was finished in 2002. The main goal of using the new digital media for modelling architectural forms was checking the new possibilities of form creation. Traditionally, searching of forms at the conceptual design stage is performed by using sketches, drawings and physical models. Our new method showed that is possible to do the same thing using the computerbased 3D modelling, experiencing no physical limitations of the 'real' substance. At the same time, at the early design stages, when formal value is sought, computer modelling can be done almost intuitively. In ours work we try to find a creative way of using computer - transforming the tool into medium. The attention was paid on exploring the possibilities characteristic for computers and not available with traditional methods of modelling. Architect’s tradition tools are effectively replaced by a computer, which create a new way of doing things.

title	Spatial Cognition in Digital Cities
source	International Journal of Architectural Computing vol. 1 - no. 4
summary	Today, digital cities are being developed all over the world. By using a city metaphor, digital cities integrate urban information and create public spaces. However, there are questions as to how to enter the new emerging digital cities, how humans perceive themselves in digital cities, and there are also issues of recognition of the digital city forms? This paper takes the idea of cognition in order to explore the structure of the new spatiality as cyberspace. By exploring the factors relating to human spatial cognition in physical space it is possible to interpret how humans perceive the spatial form of digital cities. By examining spatial experience in physical space, the interface of spatial cognition of interaction between digital cities and physical cities can be investigated. And by taking this approach, we propose an online prototype of a metaphor for a digital city.

summary	The purpose of this work is to develop needed interaction techniques for understanding the context of a digital city. In this paper, we present a framework in terms of three perspectives: information representation, physical interactions and media space design. We implement tangible media for physical interactions, allowing users to explore a digital city with respect to different positions in time-space in an interactive and intuitive manner. The time-space representation is mapped to physical media space. Our work is demonstrated in a digital 3D museum project for Tainan city in Taiwan.

summary	Digital virtual reality (VR) and the metaverse provide opportunities for the creation of cultural extensions that define our contemporary society. This has been the practice for millennia – using different technologies and media; humans have always attempted to convey experience through representational forms. The paper puts forward an initial theoretical examination of metaverse using theories on perception and subjectivity in psychology and philosophy and the implications of these in architecture and space creation, both physical and digital. It considers historical VR spaces to better understand the influence of culture and applies this to the contemporary social VR spheres. Though they offer novel opportunities, digital virtual realities and immersive spaces of today are no different than the lineage of spaces and representations that strove to do this throughout history (Grau, 2003). Using different mediums, they each provide an extension of culture that reflects society and becomes a record of their times and ideals.

title	IMPROVING NEURAL NETWORK MODELS OF PHYSICAL SYSTEMS THROUGH DIMENSIONAL ANALYSIS
source	Journal of Applied Soft Computing 2(4): 283-296.
summary	The paper presents a technique for generating concise neural network models of physical systems. The neural network models are generated through a two-stage process. The first stage uses information embedded in the dimensions or units in which the data is represented. Dimensional analysis techniques are used initially to make this information explicit, and a limited search in the neural network architecture space is then conducted to determine dimensionless representations of variables/parameters that perform well for a given model complexity. The second stage uses information available in the numerical values of the data to search for high-level dimensionless variables/parameters, generated from simple combinations of dimensionless quantities generated in the first stage and which result in concise neural network models with improved performance characteristics. The search for these high-level dimensionless variables/parameters is conducted in an enhanced representation space using functional link networks with flat or near flat architectures. The use and effectiveness of the technique is demonstrated for three applications. The first is the design and analysis of reinforced concrete beams, which is representative of the class of problems associated with the design and analysis of composites. The second is the classical elastica problem, for predicting non-linear post-buckled behaviour of columns and the third, the analysis of a bent bar under a specified combination of loads.
