summary This study attempts to investigate the sense of presence in a fully immersive virtual environment. The methodology applied in this study used protocol analysis for data collection. A preliminary experiment was conducted to explore noticeable phenomena to develop a hypothesis for the final experiments. Four different virtual reality models, representing four different kinds of virtual space, were navigated in C6 (CAVE facilities) by two human subjects. Results of the research in this direction have provided valuable understanding regarding the sense of presence in the virtual environment.

title A bodily user interface for VR-CAVE
doi https://doi.org/10.52842/conf.caadria.2005.129
source CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 2, pp. 129-135
summary The main purpose of this research is to explore how body movement can increase user’s sense of presence in the virtual reality cave (VR-CAVE). Traditionally, in architectural applications, there is no interaction between users and VR-CAVE. Visual perception is the major way of presentation. The users feel certain level of sense of presence. Therefore, in order to increase user’s sense of presence, we designed a bodily user interface as our controller which utilized user’s body movement to interact with VR. The contribution is that not only a user can easily or effortlessly control and navigate VR space but also VR navigation will directly link to the experience of walking in a physical space, which provides strong sense of presence to user.

summary The early findings of this research were presented in eCAADe 2005 International Conference, Lisbon primarily to highlight the concept of High Dynamic Range Images (HDRI) when representing architectural spaces in the form of still images. An experiment had been carried out to compare the results between HDRI rendering and ‘conventional’ lighting simulation algorithms namely ray tracing and radiosity. The results were based on static and using the same exposure factors, when capturing HDRI. This project, funded by Intensification Research Priority Area (IRPA) grant continues to present and report HDRI results in a simulation environment. In this paper, we first briefly explain on the concept of real and fake HDRI. Then a comparison experiment is conducted to compare these two methods and discuss the impact and effectiveness of the illumination computation in architectural simulation environment. In order to carry out the experiment, a few models of the architectural scenes were developed. These models were then textured with real photos and manipulated with ‘shaders’, and further rendered using fake and real HDRI techniques. As for the fake HDRI, two methods were developed. The first was using an image as the ambient map and different exposures were created by increasing the value of Hue, V of HSV and saturation. The second involved a series of digital photos with the selection of the brightest and darkest area using Adobe Photoshop to establish the scale of luminosity. A few camera movements were triggered and position for ‘real-time’ rendering simulation. The result of the experiment has shown a significant improvement on the rendering time and quality of the rendering. Finally this paper suggests the selection criteria for choosing real and fake HDRI, and how each technique can be best utilized for architectural representations in a simulation environment.

title Simulating Human Behaviour in Built Environments

summary This paper addresses the problem of predicting and evaluating the impacts of the built environment on its human inhabitants. It presents a simulation system comprising a usability-based building model and an agent-based virtual user model. The building model represents both geometric information and usability properties of design elements, and is generated automatically from a standard CAD model. Virtual users are modelled as autonomous agents that emulate the appearance, perception, social traits and physical behaviour of real users (walking, sitting, meeting other virtual users, etc.). Their behaviour model is based upon theoretical and practical environment-behaviour studies, real world data from a field study, and Artificial Life research. By inserting the virtual users in the usability-enabled building model, and letting them “explore” it on their own volition, the system reveals the interrelationship between the environment and its users. The environment can then be modified, to see how different arrangements affect user behaviours.

title Spatio-Temporally Navigable Representation and Communication of Urban Cultural Heritage
source Proceedings: VSMM 2005 International Conference on Virtual Systems and Multimedia
summary Virtual environments are effective tools for the representation and communication of cultural heritage. We suggest that an interactive, immersive and dynamic navigation of the virtual representation of the urban environment will not only convey the essence of the culture and the changes it underwent in a more comprehensible manner, but will engender a 'sense of place'—genius loci— in the visitors. This cognitive mode will help them learn about much more than the geometry and materiality of the city: it will make them 'feel' part of the event itself. By presenting a socially shareable experience, we aim to introduce the medium the character of a genuine place, and make it a social venue for active exploration, discussion and interaction.

Virtual reality surpasses both traditional media and 3D-models and offers what they cannot. The affordances of the medium, however, also have the potential to destroy the sense of place it strives to engender. It can do so by allowing a kind of ‘time travel,’ to different periods in the history of the site. This ability locates visitors not only spatially, but also temporally. Everyday experience helps us understand the meaning of spatial boundedness, but does not prepare us to deal with temporal boundedness: sensing the presence of fellow visitors at different times. In this paper we describe our experiences in producing spatio-temporally navigable virtual reconstructions of two distinct culturally significant historic sites: the neolithic village of Çatalhöyük, and the medieval city of Cairo. We demonstrate the use of spatio-temporal navigation through a dynamic, chronologically layered model that can be browsed by multiple users at the same time. Such a dynamic system for representing chronological architectural events requires the extension of our conception of place into the temporal domain. We introduce a new concept, temporal field of view (t-FOV) and discuss how it can aid us in resolving an intrinsic challenge introduced by the representation of the temporal dimension in virtual environments.

title VIRTUALITY IN ARCHITECTURE: A DESIGN METAPHOR
doi https://doi.org/10.52842/conf.caadria.2005.342
source CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 1, pp. 342-350
summary Traditionally, architecture in its design process employs physical matter, requires physical presence and relies on real world environment using conventional methods of 2D depictions such as paper and pen or 3D representations such as physical models and communicates design ideas in verbal or text-based form. The conventional design process, for example an interior design, a residential house, a commercial complex or even urban design projects, follows the same hierarchy of activities. Efforts are made to the satisfaction of both parties to give the ideas of a physical shape through sketches, drafts and models which may take weeks even months. Finally the project gets its final shape in a working drawing, 3D visualisation or model making. This process is time consuming and somewhat redundant. In recent years technology has offered architects a new tool - the virtual environment. Architects use virtual environment increasingly as device of communication and presentation of design intensions. Virtual environment enables users to interact in real-time with design but unfortunately have not been used widely in the process of design development. The aim of this paper is to investigates the relationship between present design process and the emerging technology of virtual reality, establish a relationship between the two and its influence on architecture to form a new translated design process and communication, an interface between architect and client.

summary Mindstage is a multi-user real-time 3D environment in which is embedded a lecture on film design by Christopher Hobbs. The spatial design follows the structure of the lecture, and is richly illustrated with stills and film clips. The environment, implemented in Virtools, proved to be a visually intriguing combination of architectural, filmic and virtual space, though it was found that co-presence induced some problems with the concept of time.

source CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 2, pp. 193-202
summary Traditionally urban design is perceived, communicated and created using physical and digital media. However, these realms are handled as separate entities, which hinder collaboration, understanding and communication. Collaborative Augmented Reality (AR) systems can integrate these tasks into one media type and allow a different conversation with complex issues. Human Computer Interfaces and Tangible User Interfaces play key role in AR. They allow an engagement with both the real and virtual component of an urban design project. This paper describes an urban design studio that employs AR as medium of collaboration, the theoretical framework of sense of presence, the understanding and the quality of the resulting design.

title A Representation Language for a Prototype CAD Tool for Intelligent Rooms
doi https://doi.org/10.52842/conf.acadia.2005.170
source Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 170-183
summary Intelligent rooms are a type of intelligent environment which enhance ordinary activities within the confines of a room by responding to human interaction using pervasive and ubiquitous computing. In the design of intelligent rooms, the specification of how the intelligent room enacts intelligent behavior through computational means is as integral as the geometric description. The self-aware and context-aware capabilities of intelligent rooms extend the requirements for computer-aided design tools beyond 3D modeling of objects. This article presents a Hardware as Agents Description Language for Intelligent Rooms (HADLIR) to model hardware in an intelligent room as “hardware agents” having sensor and/or effector modalities with rules and goals. End-users describe intelligent room hardware as agents based on the HADLIR representation and write agent rules and goals in Jess for each hardware component. This HADLIR agent description and the requisite software sensors/effectors constitute “hardware agents” which are instantiated into a multi-agent society software environment. The society is then bridged to either a virtual environment to prototype the intelligent room or to microelectronic controllers to implement a physical intelligent room. The integration illustrates how the HADLIR representation assists in the design, simulation and implementation of an intelligent room and provides a foundation technology for CAD tools for the creation of intelligent rooms.

title Multi-touch - the future of design interaction
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. 557-572.
summary The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

summary This paper reports on a study of the role of place in a virtual learning environment for digital media design. Using an immersive 3D Virtual World based on Active Worlds, we have created a virtual learning place for students in a Website Design course. The virtual learning place has two distinct parts: a classroom-like place surrounded by student galleries. Students can navigate and communicate (synchronous chat) within the environment in the form of an avatar (virtual person). We recorded the conversations and activities of the students in discussions held in the virtual learning place and applied a communication coding scheme to analyze their discussions. In this paper we present our approach to developing an understanding of the role of place and evidence of its effect on the conversations of design students in a virtual learning environment. We show how we identified the characteristics of place and specifically how it provides a context for identity and presence for supporting collaborative and constructivist student centred learning.

title A Framework of Haptic Design Parameters for Architects: Sensory Paradox Between Content and Representation
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. 685-700.
summary Architects—like other designers—tend to think, know and work in a visual way. In design research, this way of knowing and working is highly valued as paramount to design expertise (Cross 1982, 2006). In case of architecture, however, it is not only a particular strength, but may as well be regarded as a serious weakness. The absence of non-visual features in traditional architectural spatial representations indicates how these are disregarded as important elements in conceiving space (Dischinger 2006). This bias towards vision, and the suppression of other senses—in the way architecture is conceived, taught and critiqued—results in a disappearance of sensory qualities (Pallasmaa 2005). Nevertheless, if architects design with more attention to non visual senses, they are able to contribute to more inclusive environments. Indeed if an environment offers a range of sensory triggers, people with different sensory capacities are able to navigate and enjoy it. Rather than implementing as many sensory triggers as possible, the intention is to make buildings and spaces accessible and enjoyable for more people, in line with the objective of inclusive design (Clarkson et al. 2007), also called Design for All or Universal Design (Ostroff 2001). Within this overall objective, the aim of our study is to develop haptic design parameters that support architects during design in paying more attention to the role of haptics, i.e. the sense of touch, in the built environment by informing them about the haptic implications of their design decisions. In the context of our study, haptic design parameters are defined as variables that can be decided upon by designers throughout the design process, and the value of which determines the haptic characteristics of the resulting design. These characteristics are based on the expertise of people who are congenitally blind, as they are more attentive to non visual information, and of professional caregivers working with them. The parameters do not intend to be prescriptive, nor to impose a particular method. Instead they seek to facilitate a more inclusive design attitude by informing designers and helping them to think differently. As the insights from the empirical studies with people born blind and caregivers have been reported elsewhere (Authors 2010), this paper starts by outlining the haptic design parameters resulting from them. Following the classification of haptics into active, dynamic and passive touch, the built environment unfolds into surfaces that can act as “movement”, “guiding” and/or “rest” plane. Furthermore design techniques are suggested to check the haptic qualities during the design process. Subsequently, the paper reports on a focus group interview/workshop with professional architects to assess the usability of the haptic design parameters for design practice. The architects were then asked to try out the parameters in the context of a concrete design project. The reactions suggest that the participating architects immediately picked up the underlying idea of the parameters, and recognized their relevance in relation to the design project at stake, but that their representation confronts us with a sensory paradox: although the parameters question the impact of the visual in architectural design, they are meant to be used by designers, who are used to think, know and work in a visual way.

summary In this paper we describe the use of media and communication technologies with a special notification on video systems for the design of a technological enhanced environment. We make suggestions how architects can design environments that are more flexible and dynamic. These environments are adapted to our changing social and cultural trends. Developments in media and communication technologies allow extending the real world to a so called Tele Reality. These environments will have a certain degree of intelligence provided via computer performance. Humans will be able to receive information form anywhere and at anytime. The focus is on expanding the availability of human resources.

title Townscaping: Development of Dynamic Virtual City Augmented 3D Sketch Design Tools
source Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 105-114
summary The paper presents the development of an experimental Web-based design environment called Townscaping to be used at the conceptual stage of architectural and urban design. Inspired by Gordon Cullen's seminal work on Townscape (1960's-1970's), the idea of Townscaping is to explore how 3D digital sketch design tools could be developed to operate in connection with a dynamic virtual city system under a user's direct control. A prototype of Townscaping has been designed and implemented on the basis of an existing dynamic virtual city system. In Townscaping, a set of tools is provided for users to create and edit 3D graphic elements to be positioned directly onto the user-specified virtual city models. One of the key features of Townscaping is to enable sketching while navigation: designers can perform sketch design and gain immediate visual feedback while navigating the 3D virtual city models to any viewpoint at any moment. The current study suggests that it is feasible for virtual city models to serve as interactive urban contexts for 3D sketch design. Townscaping is considered primarily a research platform with which we are interested in investigating if designers' engaging in 3D space conceptions may be enhanced through interacting and sketching with virtual townscapes.

source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 350-354
summary This work describes results obtained from a test over an experimental prototype “Otra Andria” (OA1) designed by the investigation team of “Obra Abierta: Over the construction of an investigating and learning system in virtual environments”. OA1 is a basic tool. It show us: three simultaneous screens with editing tool bars, an integrated chat for publication and discussion, images and texts, all this in synchronized time. Tools are simultaneously accessible from all boards by the teacher, the students or between pupils. There is a web log, a personal web, and an activities’ organization space for the professors. This experience was helpful to understand the actual needs for virtual environment applications as well as e-learning problems in such cases where the know-how is not available to every attendant to the course. That means we must begin working on hyper-medial language diffusion among all teachers who want to use the ICT in all its actual potentiality. [Full paper in Spanish]

title Interfacing the Real and the Virtual: User Embodiment in Immersive Dynamic Virtual Spaces
source Learning from the Past a Foundation for the Future [Special publication of papers presented at the CAAD futures 2005 conference held at the Vienna University of Technology / ISBN 3-85437-276-0], Vienna (Austria) 20-22 June 2005, pp. 171-180
summary This paper discusses the performative boundary between the real and the virtual as it constitutes itself based on the potentials, conditions and abilities of Virtual Reality (VR), considered as both a technology and a medium. Starting from the prospects and the areas of application of 'new' technologies within the context of architecture, the paper seeks the point of intersection between an architectural perspective, a posthuman view and a technological potential. The focus thereby lies in the greatest challenge of VR, that is, the integration of the users as they interface the virtual and the real. The conditions and implications of such dynamic processes, perceived as space generating, rather than representing, are explored based on the authors' virtual environment: Uzume.

summary As proven in the past, immersive Virtual Environments can be helpful in the process of architectural design (Achten et al. 1999). But still years later, these systems are not common in the architectural design process, neither in architectural education nor in professional work. The reasons might be the high price of e.g. CAVEs, the lack of intuitive navigation and design tools in those environments, the absence of useful and easy to handle design workflows, and the quality constraints of real-time display of 3D models. A great potential for VR in the architectural workflow is the review of design decisions: Display quality, comfortable navigation and realistic illumination are crucial ingredients here. Light is one of the principal elements in architectural design, so design reviews must enable the architect to judge the quality of his design in this respect. Realistic light simulations, e.g. via radiosity algorithms, are no longer the domain of high-end graphic workstations. Today's off-the-shelf hardware and 3D-software provide the architect with high-quality tools to simulate physically correct light distributions. But the quality and impression of light is hard to judge from looking at still renderings. In collaboration with the Institute of Computer Graphics at our university we have established a series of regular design reviews in their immersive virtual environment. This paper describes the workflow that has emerged from this collaboration, the tools that were developed and used, and our practical experiences with global-light-simulations. We share results which we think are helpful to others, and we highlight areas where further research is necessary.

title Comparative Navigation System for Collaborative Architectural Design

summary As information technology continues to evolve, it is affecting all creative art forms by providing new tools and surroundings, such as virtual environments. 3D real-time simulation environments strongly support communication and navigation, enabling users to collaborate on designs using centralized or distributed environments. The persons concerned must understand the proposed design. Systems that help them gain this understanding are therefore required. An effective concept for gaining understanding is comparison. However, comparing one design proposal with another using existing systems is difficult because the users must consider their viewpoints separately. In this paper, we describe the concepts, strategies, and functions of a 3D virtual design environment for collaborative, real-time architectural design that is based on our 3D comparative navigation system and real-time simulation technology. We also evaluate the advantages and disadvantages of using this design environment to support collaborative architectural design.

title A METHOD FOR REAL TIME SPATIAL ANALYSIS OF SOUND VIA MODELING IN A CAD ENVIRONMENT, BASED ON ACOUSTICAL MEASUREMENTS
source 14th European Colloquium on Theoretical and Quantitative Geography,September 9-13, 2005, Tomar, Portugal
summary Typical modeling systems for spatial analysis employ data that represent the visual part of a landscape (e.g. relief and morphology), combined with other data about specific attributes (depending on the aims of an application). Thus, in a modeling environment, each place is described by a variety of properties that are not always visible. More of those “hidden” properties require special sensors and/or instruments to be captured and sometimes make their presence evident through human senses, such is sound. The present study takes advantage of wide spread technologies (such as GPS, VHF telecommunications and field sensors) and methodologies that are commonly used in telegeoprocessing – telegeomonitoring in order to simulate an existing acoustic environment. The aim is to acquire real time data about the sound (referenced to a particular area) and manipulate them in a CAD environment with purpose to visualize the sound influence in a specific landscape. Specifically it is proposed a method that transfers spatial data (collected from the field), directly into a modeling system (in the office, or in situ). In sequence the data is processed adequately to feed the modeling system that describes the current sound intensity of a place.
