title	Virtual Reality - Applications and Explorations
source	Academic Press Professional
summary	Virtual and Artificial Reality have become in the last few years one of the major new hype words. Subsequently there has been a plethora of glossy books and droll conference proceedings describing various systems and hardware implementation problems. As has always been discovered in computer science the major effort is in designing and building the software applications. Alan's aim has been to ignore the hardware side and concentrate on the far larger and almost impossible problem of what to do with it. This book is a collection of ten essays trying to look slightly into the future and define actual uses for Virtual Reality kits rather than showing off expensive hardware. This has resulted in a series of topics, each defines a different interface problem between the user and machine which may have some solution by using Virtual Reality. Even though the topics vary, at times drastically, Alan has managed to use editorial selection very well intertwining them into a reasonably coherent whole. The scope is too large for any single book to cover in any detail and as is inevitable important topics for example military and medicine have been excluded. Topics chosen range from traditional computer information database visualisation to planetary exploration to the Virtual Reality version of the music video and literacy in cyberspace.

title	Spatial Perception in Virtual Environments: Evaluating an Architectural Application
source	IEEE Virtual Reality Annual International Symposium, 1993, Seattle
summary	Over the last several years, professionals from many different fields have come to the Human Interface Technology Laboratory (H.I.T.L) to discover and learn about virtual environments. In general, they are impressed by their experiences and express the tremendous potential the tool has in their respective fields. But the potentials are always projected far in the future, and the tool remains just a concept. This is justifiable because the quality of the visual experience is so much less than what people are used to seeing; high definition television, breathtaking special cinematographic effects and photorealistic computer renderings. Instead, the models in virtual environments are very simple looking; they are made of small spaces, filled with simple or abstract looking objects of little color distinctions as seen through displays of noticeably low resolution and at an update rate which leaves much to be desired. Clearly, for most applications, the requirements of precision have not been met yet with virtual interfaces as they exist today. However, there are a few domains where the relatively low level of the technology could be perfectly appropriate. In general, these are applications which require that the information be presented in symbolic or representational form. Having studied architecture, I knew that there are moments during the early part of the design process when conceptual decisions are made which require precisely the simple and representative nature available in existing virtual environments.

title	Understanding Shared Space for Informal Interaction among Geographically Distributed Teams
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. 41-54.
summary	In a design project, much creative work is done in teams, thus requires spaces for collaborative works such as conference rooms, project rooms and chill-out areas. These spaces are designed to provide an atmosphere conducive to discussion and communication ranging from formal meetings to informal communication. According to Kraut et al (E.Kraut et al., 1990), informal communication is an important factor for the success of collaboration and is defined as ‚Äúconversations take place at the time, with the participants, and about the topics at hand. It often occurs spontaneously by chance and in face-to-face manner. As shown in many research, much of good and creative ideas originate from impromptu meeting rather than in a formal meeting (Grajewski, 1993, A.Isaacs et al., 1997). Therefore, the places for informal communication are taken into account in workplace design and scattered throughout the building in order to stimulate face-to-face interaction, especially serendipitous communication among different groups across disciplines such as engineering, technology, design and so forth. Nowadays, team members of a project are not confined to people working in one location but are spread widely with geographically distributed collaborations. Being separated by long physical distance, informal interaction by chance is impossible since people are not co-located. In order to maintain the benefit of informal interaction in collaborative works, research endeavor has developed a variety ways to shorten the physical distance and bring people together in one shared space. Technologies to support informal interaction at a distance include video-based technologies, virtual reality technologies, location-based technologies and ubiquitous technologies. These technologies facilitate people to stay aware of other‚Äôs availability in distributed environment and to socialize and interact in a multi-users virtual environment. Each type of applications supports informal interaction through the employed technology characteristics. One of the conditions for promoting frequent and impromptu face-to-face communication is being co-located in one space in which the spatial settings play as catalyst to increase the likelihood for frequent encounter. Therefore, this paper analyses the degree to which sense of shared space is supported by these technical approaches. This analysis helps to identify the trade-off features of each shared space technology and its current problems. A taxonomy of shared space is introduced based on three types of shared space technologies for supporting informal interaction. These types are named as shared physical environments, collaborative virtual environments and mixed reality environments and are ordered increasingly towards the reality of sense of shared space. Based on the problem learnt from other technical approaches and the nature of informal interaction, this paper proposes physical-virtual shared space for supporting intended and opportunistic informal interaction. The shared space will be created by augmenting a 3D collaborative virtual environment (CVE) with real world scene at the virtual world side; and blending the CVE scene to the physical settings at the real world side. Given this, the two spaces are merged into one global structure. With augmented view of the real world, geographically distributed co-workers who populate the 3D CVE are facilitated to encounter and interact with their real world counterparts in a meaningful and natural manner.

summary	Jaron Lanier is a major spokesperson of our society's hottest new technology: VR or virtual reality. He expressed his faith in the VR movement in this quote which appears in The User's Guide to the New Edge published by Mondo 2000. In its most technical sense, VR has attracted the attention of politicians in Washington who wonder if yet another technology developed in the United States will find its application across the globe in Asia. In its most human element, an entire "cyberpunk movement" has appealed to young minds everywhere as a seemingly safe form of hallucination. As architecture students, educators, and practitioners around the world are becoming attracted to the possibilities of VR technology as an extension of 3D modeling, visualization, and animation, it is appropriate to consider an overview of virtual reality. In virtual reality a user encounters a computersimulated environment through the use of a physical interface. The user can interact with the environment to the point of becoming a part of the experience, and the experience becomes reality. Natural and instinctive body movements are translated by the interface into computer commands. The quest for perfection in this human-computer relationship seems to be the essence of virtual reality technology. To begin to capture the essence of virtual reality without first-hand experience, it is helpful to understand two important terms: presence and immersion. The sense of presence can be defined as the degree to which the user feels a part of the actual environment. The more reality the experience provides, the more presence it has. Immersion can be defined as the degree of other simulation a virtual reality interface provides for the viewer. A highly immersive system might provide more than just visual stimuli; for example, it may additionally provide simulated sound and motion, and simultaneously prevent distractions from being present.

title	Understanding the AR-VR Based Architectural Design Workflow among Selected Danish Architecture Practices
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 381–388

summary	Virtual reality (VR) and augmented reality (AR) have been proposed to be additional architectural design mediums for at least 25 years (Dagit, 1993). Despite rapid technical and technological development, it has not been adopted into architectural design practices as compared to academia and research. Surveys from the American Institute of Architects (AIA) and Royal Institutes of British Architects (RIBA) demonstrate the state of architectural practices; 72% of architects and 65% of architects respectively are not using any kind of virtual, augmented, or mixed reality in their practices(RIBA and Microsoft, 2018; Hampson, 2020). In this paper, the authors investigate the state of practices, issues, challenges, and opportunities of the utilization of virtual, augmented, and mixed realities in six architectural practices in the Danish context. Three of the practices are large architectural practices, one medium-sized practice specializing in institutional, healthcare and cultural architecture, and one firm designing private family houses, kindergartens, daycares and places for people with disability and, one experimental design studio. All these practices have used VR/AR in their projects to various degrees. In recent years Danish architectural practices have been involved in various VR/AR-based exhibitions, demonstrations, and tool developments to promote the usage of the same in design practice. Through a set of qualitative interviews with personnel from key architectural practices, the authors would like to demonstrate the present state of practices. The investigation explores the usage of VR and AR in Danish architecture practices by identifying challenges and opportunities regarding skill levels, architectural typology, use cases, toolchains, and workflow and shows similarities and differences between traditional and VR-based design processes. The main findings show how VR/AR-based visualization helps architects to perceive spatiality and also ushers creativity through immersion and overlays.

summary	The boundaries of augmented reality in the academic field are now being explored at an ever increasing level. In this paper we present the initial findings of an educational project focusing on the use of augmented reality in the design process of an architectural student. The study seeks to evaluate the use of AR as a tool in the design stages, allowing effective exploration of spatial qualities of design projects undertaken in the studio. The learning process is guided by the exploration and detection of a design idea in both form and function, with the virtual environment providing a dynamic environment (Mantovani, 2001). This is further reflected in the constructivist theory where the learning processes use conceptual models, which are used to create incremental stages that become the platform to attain the next [Winn, 1993]. The additional benefit of augmented reality within the learning journey is the ability of the students to visually explore the architectural forms they are creating in greater depth.

title	Exploring and Illustrating
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi	https://doi.org/10.52842/conf.ecaade.1993.x.l5o
summary	CAD, in its usually available forms, is wonderful at illustrating proposed architectural objects. But, as I argued last year at the Barcelona meeting, it is not so good at helping us extend the richness and development of architectural ideas—at the "back of envelope" and other developmental Ievels—indeed, it is (for pragmatic reasons—and others) actually restrictive of change, what-if, suck-it-and-see, etc. I shall describe a work environment, which we have been developing since last year in Portsmouth, in which computing is used by students to assist the generation, testing and extension of ideas: in which exploring takes precedence over illustrating. The central notion of this environment involves the extension and manipulation, through co-operative sharing of a joint "resource base" of computer stored images (recognising origination rather than ownership), and (parts of) which may be copied and transformed by group members as they seek to develop, enrich and extend their ideas. Transformations may be intentional, but some occur through the limits of our computational medium such as compression losses, file formats, colour depth and resolution and are welcomed as a contribution made by the computing medium used. Images are located through a developing, shared filing system, picture search and history trace. The environment relies on a small suite of computers wile a powerful machine acting as a fileserver and undertaking central, computationally-intensive tasks. For this environment, we have chosen software carefully, and the choice will be described. We have also developed a small, but crucial program that traces developments in the shared resource base—in what is, in effect, our own, operational CyberSpace (as distinct from a Virtual Reality). Through these mechanisms, we believe we are able to evade the limitation set by Ross Ashby's "Law of Requisite Variety", thus expanding the creativity-base of participating designers (students). There are no "scientific results", but we believe the reasoning behind, and the activity and exploration of our environment is valuable in itself, and may be of interest to collegues.

source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 405-421
summary	The integrated design, construction, and management of buildings are described as being of unlimited complexity. The data structures required to support these tasks cannot be predefined and have- to be worked out during the design process. An instrument that integrates weakly and strongly structured data is necessary. A4 proposes - as a minimal structuring mechanism - the position of information in a dataspace. It offers diverse additional and optional structuring mechanisms. Examples from different domains show the particular strengths of the A4 integration model.

title	Building a spatially immersive display - HUTCAVE
source	Helsinki University of Technology, Espoo, Finland
summary	A spatially immersive display is a display that surrounds the user, thus removing or alleviating many disadvantages the common virtual reality systems, such as head-mounted displays have. The most common example of these spatially immersive displays is the CAVE, "CAVE Automatic Virtual Environment", first built at University of Illinois, in 1993. It combines a large field-of-view with high-resolution images and a high frame refresh rate. In this work, the current Virtual Reality (VR) and Virtual Environment (VE) systems are examined, and then the CAVE construction is presented. Principles of stereo vision are explained and current methods of obtaining both autostereoscopic and stereopsis-based vision are reviewed. Aspects of different projection methods, screens, mirrors, projectors, tracking equipment, and computing systems are examined. Also, recent work in CAVE audio, so far neglected in research, is presented. Some of the mathematics is also explained, since in most CAVE-systems some sort of optical folding is necessary. Two cases of CAVE construction are presented, both at the Helsinki University of Technology. The first is a single-wall installation built as a temporary system, and the second is a four-sided CAVE at a new location, superseding the temporary installation. Finally the conclusions are presented, both from the process management point of view, and from the technical point of view, examining the good and bad points of the chosen solutions.

summary	Since 1993 schools of architecture all over the world conduct in various forms of Virtual Design Studio (VDS). They have become an established part of teaching design within the digital realm. They vary in task and structure, are purely text-based or include various forms of interactive, synchronous or asynchronous collaboration. However, ‘virtual’ always refers to the method of communication and exchange of design and ideas. Students have never designed within immersive virtuality. This paper describes the first successful attempt to conduct a Joint Design Studio, which uses Virtual Environment (VE) as tool of design and communication between the remote partners. This first VeDS focused on how architectural students make use of this particular different approach to design within immersive three-dimensional VEs. For example, the students created 3D-immersive design proposals, explored dependencies to textual description of initial intentions and communicated between local and remote team-partners in immersive VE as well as textbased communication-channels. The paper subsequently describes the VeDS, its set-up, realization and outcome. We discuss frameworks and factors influencing how architectural students communicate their proposals in immersive VeDS, and how this new approach of design studio enables new forms of design expressions.

title	Toward a procedure of computer simulation in the restoration of historical architecture

summary	In the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

title	Designing in Virtual Reality: Perception-Action Coupling and Form Semantics Short Papers (Talks): Visual Languages and Virtual Reality
source	Proceedings of ACM INTERCHI'93 Conference on Human Factors in Computing Systems -- Adjunct Proceedings 1993 pp. 11-12
summary	In this paper, we describe work on a CAD package we are developing for use in virtual reality. Although this research is only preliminary, it demonstrates some advantages of designing in virtual reality. We describe these advantages in terms of ecological approach to perception, focusing on two of the implications of this approach: the role of perception-action coupling in producing true direct manipulation, and the desirability of providing perceptual information about the affordances of objects in the design environment.

title	Designing the Future: The Computer Transformation of Reality
source	Thames and Hudson, Hong Kong
summary	A coffee table book on computer applications? Well, yes, because it does deal largely with matters of graphic design in architecture, fashion and textiles, painting, and photography; but it also has items which might be of interest in its sections on digital publication, typography, and electronic communication in general. It also seeks to discuss the way in which these applications may force us to change the way we think. Robin Baker writes in an unfortunately stiff and abstract manner about the impact computer programmes have had on the world of art and design, but the graphic images and extended picture captions help to keep the reader awake - even though the main text sometimes disappears for two or three double page spreads on end. There are also smatterings of pretentious art-world-speak about 'solving certain spatial problems' (in the design of curtain fabrics or teapots) and the introduction (inevitable?) of new jargon: 'shape grammar'(a list of so-called shape 'rules'), 'repurposing' (putting somebody else's work to new use) and 'genetic algorithms' (sculptural designs based on re-processed organic shapes - most of which look like stomach tumours). In his favour, Baker very generously credits students and commercial designers who have produced the effects he describes and illustrates so well. For writers, he sketches in the possibilities of Hypertext and Hypermedia and points to the future of Hyper publishing which he (and Rupert Murdoch)believes will be with us before the end of the century. He seems to have a good oversight of what is possible and practicable - though one wonders how up-to-date the view is when his book may have begun its life anything up to three years ago. He usefully points out that much new technology exists in or drags along with it the forms of earlier periods - so that in an age of electronic communication we still have printed books as a dominant cultural form. Maybe this is as it should be - but Baker makes a persuasive case for the claim that All This is Going to Change.

title	Common Illumination between Real and Computer Generated Scenes
source	Proceedings Graphics Interface '93, pp. 254-262, 1993
summary	The ability to merge a real video image (RVI) with a computer- generated image (CGI) enhances the usefulness of both. To go beyond "cut and paste" and chroma-keying, and merge the two images successfully, one must solve the problems of common viewing parameters, common visibility and common illumination. The result can be dubbed Computer Augmented Reality (CAR). We present in this paper techniques for approximating the common global illumination for RVIs and CGIs, assuming some elements of the scene geometry of the real world and common viewing parameters are known. Since the real image is a projection of the exact solution for the global illumination in the real world (done by nature), we approximate the global illumination of the merged image by making the RVI part of the solution to the common global illumination computation. The objects in the real scene are replaced by few boxes covering them; the image intensity of the RVI is used as the initial surface radiosity of the visible part of the boxes; the surface reflectance of the boxes is approximated by subtracting an estimate of the illuminant intensity based on the concept of ambient light; finally global illumination using a classic radiosity computation is used to render the surface of the CGIs with respect to their new environment and for calculating the amount of image intensity correction needed for surfaces of the real image. An example animation testing these techniques has been produced. Most of the geometric problems have been solved in a relatively ad hoc manner. The viewing parameters were extracted by interactive matching of the synthetic scene with the RVIs. The visibility is determined by the relative position of the "blocks" representing the real objects and the computer generated objects, and a moving computer generated light has been inserted. The results of the merging are encouraging, and would be effective for many applications.

summary	At the Institute of Urban Planning at the University of Stuttgart early experiments were made with the help of endoscopes in the late 1970’s. The intention was to find new instruments to visualize urban design projects. The first experiment included the use of a 16 mm film of a 1:170 scale model of the market place at Karlsruhe, including design alternatives (with trees, without trees etc). The film was shown to the Karlsruhe authorities, who had to make the decision about the alternatives. It was said, that the film gave a great help for the decision-making and a design proposition had never before been presented in such understandable way. In 1975-77, with the support of the Deutsche Forschungsgemeinschaft (German Research Foundation) an investigation was carried out into existing endoscopic simulation facilities, such as those in Wageningen, Lund and Berkeley. The resulting publication was mainly concerned with technical installations and their applications. However a key question remained: ”Can reality be simulated with endoscopy?” In 1979-82, in order to answer that question, at the Institute was carried out the most extensive research of the time, into the validity of endoscopic simulation. Of special importance was the inclusion of social scientists and psychologists from the University of Heidelberg and Mannheim. A report was produced in 1983. The research was concerned with the theory of model simulation, its ways of use and its users, and then the establishment of requirements for effective model simulation. For the main research work with models or simulation films, psychological tests were developed which enabled a tested person to give accurate responses or evidence without getting involved in alien technical terminology. It was also thought that the use of semantic differentials would make the work imprecise or arbitrary.
