title	Creating Immersive Virtual Landscapes A User-Centered Approach to Enhance Depth Perception in Head-Mounted Displays
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 1, Graz, 20-22 September 2023, pp. 149–158

summary	This paper investigates the effects of color, luminance, and transparency as depth distortion cues in Virtual Reality (VR) Head-mounted Displays (HMD). The aim is to tackle more in-depth immersion: focusing on interaction accuracy with transparent objects in HMDs. Due to the illumination and absence of texture, transparent objects are mainly displayed with colors. Recently, studies on transparent hands and objects have elucidated potential approaches regarding interaction with transparent elements. However, findings have not considered color and luminance as depth distortion cues for interacting in virtual landscapes. This paper used the forced-choice pairwise comparison experiment method and evaluated data based on the Kendall coefficient of agreement and consistency. Reverse effects of transparency on color and luminance are discovered. Cool colors are perceived nearer than warm colors in 90% transparency. Dark colors are sensed closer than bright colors in high transparency levels. These results reject the classical effects of color and luminance within VR HMDs. These findings help VR design tool developers who emphasize a particular use of depth cues. Designers can utilize the studied effects of color and luminance on transparent objects as an advantage in designing more interactive and immersive virtual landscapes.

summary	During recent years, developments in the area of virtual reality and its applications in architecture have undergone a number of important transformations that point out the need of an updated revision and adjustment as regards its current situation status and also that which concerns its potentialities within a foreseeable future. This paper seeks to provide an ample vision about recent developments of VR in architectural applications and, also, about its potential developments within the settings provided by such imminent phenomena as the upcoming Internet II and its future impact on the three dimensional and multisensorial qualities of the information that will move within cyberspace in the next decades. The paper also comments on experiencies underway at the Laboratory of Advanced Techniques in Design, Faculty of Architecture and Urbanism, Universidad Central de Venezuela in collaboration with the Laboratory of Computer Graphics, School of Computing, also at UCV, Caracas. Finally, a number of considerations and conjectures are dedicated to the new field of VR multi-access worlds and its potential to virtual architectural modeling in the Intenet-WWW.

title	Augmented Reality for Construction From Steam-Bent Timber
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 191-200
doi	https://doi.org/10.52842/conf.caadria.2022.2.191
summary	Digital models viewed in augmented reality can serve as guides to form and assemble parts during construction and reduce the need to build temporary formwork or sub structures. However, static digital models are often inadequate for describing the behaviour of material that is dynamically formed over time, leading to breakages and difficulty following augmented reality guides during assembly. To address this issue, we propose a method for fast and approximate simulation of material behaviour using a goal-based physics solver, enabling the design and fabrication of steam bent timber parts using an adaptable system of sparse formwork. Through the design and construction of a pavilion from steam bent timber we demonstrate that approximate simulation of material behaviour is adequate for wide tolerance construction by hand and eye in augmented reality, avoiding part breakages and accumulative error.

doi	https://doi.org/10.52842/conf.acadia.2018.088
summary	The construction industry’s reliance on two-dimensional documentation results in inefficiency, inconsistency, waste, human error, and increased cost, and limits architectural experimentation with novel form, structure, material or fabrication approaches. We describe a software platform that enables designers to create interactive holographic instructions that translate design models into intelligent processes rather than static drawings. A prototypical project to design and construct a pavilion from bent mild steel tube illustrates the use of this software to develop applications assisting with the design, fabrication, assembly and analysis of the structure. We further demonstrate that fabrication within mixed reality environments can enable unskilled construction teams to assemble complex structures in short time frames and with minimal errors, and outline possibilities for further improvements.

summary	To address this issue, we propose a method for guided fabrication in augmented reality using real time comparisons between depth scans of as built conditions and target conditions defined by design models. Through the design and fabrication of a small proof of concept prototype from paper strips, we demonstrate that guided fabrication is adequate for high speed, approximate and ad-hoc fabrication of complex surface geometries without the need for extensive rationalization for fabrication constraints or explicit documentation of parts.

title	An interactive Web-based teaching tool for simplified 3D analysis of solar rhythms
source	Automation in Construction 8 (2) (1998) pp. 181-194
summary	This case study presents the World Wide Web as an appropriate medium for architectural teaching. The prototypical tool VRSolar uses simple programming and existing Web resources to help in the teaching of topics related to the movement of the sun and its effects on the built environment. Using JavaScript, this tool is capable of generating real time Web content in html and VRML based on user input. Accessible on the Web from within a standard Web browser, this tool calculates the solar positions of any location on earth and indicates the solar access to a given site in the form of a three-dimensional Web page, which the user can view, navigate through, and animate.

title	Architecture not Aided – Architecture Transformed
source	CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 193-207
summary	Permeating of new technologies (computer aided design) into architectural design causes essential changes in its structure. It is the process, set of mutually interrelated different social, political, cultural occurrences, which happen in the present time. Everything what is new, brings either fear or unreliable expectations. The reflection is needed to name what we will have to deal with in architecture. Architecture is not a stable sphere, and as other disciplines is subject to processes of change, which result from the specificity of the time. We need to be aware of the consequences these processes could cause. I located them in six general fields: 1.) Transformation of the tool traditional tools - set of singular, autonomous, mono-functional devices, which together make the environment; computer - one tool consisting of non-autonomous internal and external units, multifunctional; itself it is the environment, system; 2.) Transformation of the medium. As the medium is the message (M.McLuhan), so the essence of media is transmission. Traditional transmission in architectural design is direct (transmission is equivalent to recording, notation), computer based transmission is indirect (transmission is not equivalent to recording); 3.) Transformation of perception, imagination and thinking. Perception - in the process of design directly relates to media Indirect transmission - causes also rupture in direct relation between record and perception (mainly in modelling); simulated object is a stage in the process. Imagination, thinking - influenced with perception, with data transmitted from the medium - can be seen as inspiration; 4.) Transformation of cooperation and communication. It is to be done by elimination of some of intermediate stages in the design process and use of multimedial communication systems (Internet); 5.) Transformation of methodology. Same as in 4 with the possibility of simultaneous shifting in the hierarchy of design stages - almost full reversal of the process possible (regardless of individual methodology) - if needed of course; 6. Transformation of architecture itself. This concerns very deeply point 3 - and it rooms that natural consequences of the changes in perception, imagination and thinking should result in the new understanding of architecture - not as electronic methaphone, but as a sphere relevant (?!) to the vision of the world, which, as we see, is dramatically changing. The basic issue to accept is that this vision of the world should be interpreted individually. Personally.

title	Architecture of Many Media (Architecture is Many Media)
source	Multimedia and Architectural Disciplines [Proceedings of the 13th European Conference on Education in Computer Aided Architectural Design in Europe / ISBN 0-9523687-1-4] Palermo (Italy) 16-18 November 1995, pp. 395-400
doi	https://doi.org/10.52842/conf.ecaade.1995.395
summary	Basis issues concerning media need redefining, because new media should not be perceived and approached according to traditional conventions. Present understanding of a medium as a mean of linear transmission, with the primary role of sender is no more sufficient, is too simple. The possibility of mutual and multidirectional communication in the real time makes the distinction between sender and receiver not so clear. The roles are effacing, but actions, processes are not. When receiver becomes sender, the process of receiving is always distinct from sending. The importance of the process, the attention must move towards a temporal process of transmitting of the receiving. When the process changes, the message (even when ´only´ its form) changes, receiving changes because it is an active action. This paper is the collection of ideas for discussion.

source	The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, p. 214
doi	https://doi.org/10.52842/conf.ecaade.1994.x.o5l
summary	Architectural design is always concerned with form to things. It is the sphere or action where meanings are to be expressed and further on - received (by a receiver), felt, understood. "Meanings" mean not only rational information. The matter is to reach the essence and to master ways appropriate to expose and interprete it. Quality of the form decides whether architectural or any work is worth attention or not and to what degree. Form is an attribute of a thing. It is form that "speaks". This linguistic metaphore shows one of natural, inborn features of things and states. However, questions appear: 1. Does everything have form? 2. Is the form an objective term? 3. What limitations of the definition of the form to accept- if any? The friendly environment for creating form consists of conscious intentions plus open mind. Rules are certain, but liquid. Every formal communication system may be widened individually. The only limitation is to be received according to intentions. So, incredibly, the infinite number of combinations, even within one system, may be possible.

title	Towards Affective Architectural Computing: An Additional Element in CAAD
source	CAD Creativeness [Conference Proceedings / ISBN 83-905377-0-2] Bialystock (Poland), 25-27 April 1996 pp. 121-135
summary	The sphere of computing, in general, is the sphere of confusion. First, computers', thanks to (or because o) the indirect way of communicating "with" them, have not become yet the obvious and natural extension of human abilities - as TV set, radio or cars already have. It is probably because of the feeling, that they are, more or less, for specialists and that they require special knowledge or skills. In a way it is true, but surely it will change within a few years, when they become everyday tools of education at schools or just toys for children. Second, there is also the feeling or wish, that every computer is able to do everything we want - from, lets say, writing a letter, washing the dishes to very complex things as, for example, designing architecture. This is the dream of universal artificial intelligence, which should be a perfect servant, which not only listens to, but also predicts our wishes.

summary	The paper presents the work in progress: formal experiments in computer modelling, accenting a certain shift approaching the computer - creation, not just modelling (simulating). Two main approaches to architectural computing are formulated: creative and simulative, where computer creation involves and enables quick formal synthesis, and where simulation requires analysis. The attention is paid on creation. This paper as well as the research project on abstract modelling is sponsored from the Polish Committee of Scientific Research.

source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 427-432
doi	https://doi.org/10.52842/conf.ecaade.2005.427
summary	Design of reactive, intelligent and sensate spaces is a form of spatial design that demands creating thinking in terms of non-permanent, non-tactile and sometimes non-visual media. This implies spatial conceptualization using sensory modalities that are ordinarily of secondary importance to vision in design, such as proprioception and hearing. This paper explores these alternative modalities for both spatial perception and spatial expression with a view to developing innovative interfaces for spatial design. Computer games and installation art environments are analyzed for use of alternative spatial immersion techniques. This informs a physical spatial interaction environment. Motion-capture input and digital auditory output provide real-time, intuitive feedback to the user. Useful interaction strategies are acquired that can be used in a non-intrusive manner in sensate spaces for communal, commercial, or public contexts.

doi	https://doi.org/10.52842/conf.acadia.2011.372
summary	Multidisciplinary efforts that have shaped the current integration of multimedia into architectural spaces have primarily been conducted by collaborative efforts among art, engineering, interaction design, informatics and software programming. These collaborations have focused on the complexities of designing for applications of multimedia in specific real world contexts. Outside a small but growing number of researchers and practitioners, architects have been largely absent from these efforts. This has resulted in projects that deal primarily with developing technologies augmenting existing architectural environments. (Greenfield and Shepard 2007)This paper examines the potential of multimedia and architecture integration to create new possibilities for architectural space. Established practices of constructing architecture suggest creating space by conventional architectural means. On the other hand, multimedia influences and their effect on the tectonics, topos and typos (Frampton 2001) of an architectural space (‘multimedia effects matrix’) suggest new modes of shaping space. It is proposed that correlations exist between those two that could inform unified design strategies. Case study analyses were conducted examining five works of interactive spaces and multimedia installation artworks, selected from an initial larger study of 25 works. Each case study investigated the means of shaping space employed, according to both conventional architectural practices and the principles of multimedia influence (in reference to the ‘multimedia effects matrix’) (James and Nagasaka 2010, 278-285). Findings from the case studies suggest strong correlations between the two approaches to spatial construction. To indicate these correlations, this paper presents five speculative integrative design strategies derived from the case studies, intended to inform future architectural design practice.

title	An Allegorical Architecture: A Proposed Interpretive Center for the Bonneville Salt Flats
source	ACADIA Quarterly, vol. 18, no. 1, pp. 18-19
doi	https://doi.org/10.52842/conf.acadia.1999.018
summary	Architecture is the physical expression of man's relationship to the landscape- an emblem of our heritage. Such a noble statement sounds silly into today's context, because civilized society has largely disassociated itself from raw nature. We have tamed the elements with our environmental controls and turned the deserts into pasture. I find much of the built environment distracting. Current architecture is trite, compared to geologic form and order. I visited the Bonneville Salt Flats- (Utah's anti-landscape) in the summer of 1997. The experience of arriving at the flats exceeded my expectations. I was overpowered by a sense of personal insignificance - a small spot floating on a sea of salt. The horizon seemed to swallow up the sky. Off in the distance I noticed a dark fleck. It looked as foreign as I felt on this pure white plane. I drove across the sticky salt toward it, only to discover an old rusty oil barrel half submerged in salt. In my mind, the barrel has a history. It tells the story of a man's attempt at achieving a goal, or maybe it represents a broken dream left to corrode in the alkali flats. The barrel remains planted in the salt as a relic for those who venture into the white wilderness. This experience left me to ponder whether or not architecture can serve the same purpose - telling the story of a place through its relationship to a landscape, and connection to events.

source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	This work shows the use of digital technologies in the morphological, spatial and functional understanding of the Baralt Square, through the partial reconstruction of this urban space with three-dimensional models, from its creation to present times, to generate its past and current scenarios, its economic, social and urban life, inhabitants and lifestyle. The purpose of this research is to find the formalization levels for the Baralt Square space, its variations and .intangible urban. identity, derived from the various uses given to it as well as from the development of activities it has undergone, which have generated a collective and dynamic space, rather than from the result of planning. To achieve this, a work methodology will be applied to obtain answers regarding the creation of this public space, through virtual urbanism. The use of digital technologies in the historical, architectonic and urban reconstruction of the square will allow for finding its origins, the collective memory and the intangible.

summary	This research proposed an urban platform designed to facilitate the sharing of community experience in the spatial context of traditional 'alley'. 'Smart Alley' refers to a smart space in which various urban media, supported with IoT technologies, interplays so that the creation and consumption of media content leads to vivid social interactions in this specific urban space. The proposed urban platform is driven by the Content Management System (CMS). An urban ontology works as a logic model of the CMS. This paper focused on the conceptualization and design of both CMS and ontology modules within the smart alley framework. Outcomes from the 'Smart Alley Workshop' are presented, which was conducted to develop smart services to utilize the smart alley platform.
