title	Mobile Augmented Heritage: Enabling Human Life in Ancient Pompeii
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 396-415
summary	We propose a new methodology for real-time mobile mixed reality systems that feature realistic simulations of animated virtual human actors (clothes, body, skin, face) who augment real environments and re-enact staged storytelling dramas. Although initially targeted at Cultural Heritage Sites, the paradigm is by no means limited to such subjects. The abandonment of traditional concepts of static cultural artifacts or rigid geometrical and 2D textual augmentations with 3D, interactive, augmented historical character-based event representations in a mobile and wearable setup, is the main contribution of the described work as well as the proposed extensions to AR Enabling technologies: a VR/AR character simulation kernel framework with character to object interaction, a markerless camera tracker specialized for non-invasive geometrical registration on heritage sites and a PRT mixed reality illumination model for more consistent real-virtual real-time rendering. We demonstrate a real-time case study on the actual site of ancient Pompeii.

title	Virtual Reality Model of the Northern Sluice of the Ancient Dam in Marib/Yemen by Combination of Digital Photogrammetry and Terrestrial Laser Scanning for Archaeological Applications
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 340-354
summary	In this paper the potential of digital photogrammetry and terrestrial laser scanning in combination is demonstrated in the recording and 3D CAD construction of the northern sluice of the ancient dam in Marib/Yemen, which is located approx. 150 kilometre east of the capital city Sana'a, close to the inner Arabic desert. The Yemeni government proposed for initiation of the building into the list of the UNESCO world cultural heritage. This described project work is a co-operation between the Commission for Archaeology of Non-European Cultures (KAAK) Bonn of the German Archaeological Institute (DAI) and the department Geomatics of the HafenCity University Hamburg. The object recording was carried out in January 2006 with the digital SLR camera Fujifilm FinePix S2 pro and the terrestrial laser scanner Trimble GS100 during the archaeological excavations. The northern sluice was reconstructed and visualized as a computer-based 3D CAD model for archaeological investigations (as-builtdocumentation of the excavations) and for future tourism advertising and publication purposes.

title	Simulating the Use of Ancient Technology Works Using Advanced Virtual Reality Technologies
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 256-282
summary	This paper introduces a novel framework for the modeling and interactive simulation of ancient Greek technology works with the use of advanced virtual reality technologies. A novel algorithm is introduced for the realistic and efficient resolution of collisions that is based on an advanced collision detection approach that can also calculate in real-time the force that should be fed back to the user using a haptic device. Thus, the user is capable of manipulating the scene objects in the environment using haptic devices to simulate the sense of touch and stereoscopic imaging so as to be immersed in the virtual environment. Moreover, the virtual hand that simulates the user's hand is modeled using superquadrics so as to further increase the speed of the simulation and the fidelity of the force feedback. Extended evaluation of the system has been performed with visitors of the Science Center and Technology Museum of Thessaloniki.

title	RQS - Reverse Quadratura for Surveying
doi	https://doi.org/10.52842/conf.ecaade.2007.615
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 615-620
summary	This research is based on the development of a new method for surveying single and double curved surfaces using an application of an ancient perspective method for representing a picture on a complex surface. The procedure enables the user to have some detailed cross-points of a grid in order to simplify the survey operation. Another phase of the work is to take some double-pictures of the element, according of the method I shall describe in the paper. The photographs of the single element, with the projection of the regular grid, can be processed with every Image-Based Modeling Software in order to obtain – with the usual calibration methods – the digital “mapped with reticulum” model of the curved surface we are analyzing. The final step enables the user to improve the quality of the textured model, switching from the grid-textured photographs to the simple-textured one. This research is part of a more general theoretical and experimental Academic research that has the aim of studying the ancient drawing methods of in order to find some analogies with the digital technology applied to the study of architectural buildings.

title	SecondLife: A Computer-Mediated Tool for Distance-Learning in Architecture Education?
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 17-34
summary	Despite the importance of distance learning for its ability to reach a wide audience, easiness to access materials, and its lower cost compared to traditional learning, architecture education has not been well served by distance education. This is because it has a higher level of learning objectives, it is taught by coaching methodologies, and involves nonverbal forms of communication. One of the most common learning methods used in the design studio is the Criticism/Critique, which is a graphic and oral type of communication between the tutor and the students. In this investigation, Second Life, a massive multi-user online virtual environment that offers three-dimensional spatial capabilities via Avatars impersonation, is used as a computer-mediated tool for text and graphic-based communication in a distance learning situation. The study describes a demonstration experiment where students had to communicate with their tutor, display and describe their projects at a distance, in a purposely designed criticism space in SecondLife. The main objective of this paper is to observe and document the effects and the use of SecondLife virtual environment as an online 3D graphical-based tool of computer-mediated communication in distance learning in architecture education. The study also answers some questions: How well did the students use the tools of the medium provide? Was there a sense of personal communication and realism gained through using Avatars in the virtual environment? Did SecondLife provide a successful means of communication for a graphic-based context? And what are the students’ opinions about the learning environment? Using multiple methods of data collection, mainly based on an electronic observation of the experiment, questioning the participants before and after the experiment, and the analysis of the chat transcripts, the study presents descriptive results of the experiment, and discusses its main features. Proposals for modifications are made for future replications.

title	TangiCAD: Tangible Interface for Manipulating Architectural 3D Models
doi	https://doi.org/10.52842/conf.caadria.2007.x.x8o
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	This paper presents an interface for interacting with tangible objects to produce and edit architectural 3D models, called TangiCAD. TangiCAD is a tangible/virtual construction kit which allows architects to manipulate virtual models using easy hand control of tangible cubes, as an alternative interface for 3D modeling. It consists of a set of tangible cubes representing architectural elements, such as walls, columns, slabs,…etc., in addition to some editing operations. With more developed versions, the paper argues that architects could use tangible interfaces to carry out 3D modeling in an intuitive way, using their "flip-the-box" hands-on movement.

title	Advanced Digital Manufacturing Techniques (CAM) in Architecture
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 67-80
summary	Building projects today are not only born out digitally, but they are also realized digitally through "file-to-factory" processes of computer aided manufacturing (CAM) and computer numerically controlled (CNC) technologies. It was the challenge of constructability that brought into question, what new instruments of practice are needed to take advantage of the opportunities opened up by the digital modes of production, instead of whether a particular form is buildable. In this case of building construction, architects could design with attention to innovative details, afforded by unique shapes and sizes, knowing that whatever they created on their computer screen could be fabricated digitally for an affordable price. The aims of the research are to discuss and analyze the digital manufacturing techniques (CAM) in architecture and its fabrication, production process. To understand how these technologies fit within a broader context of architectural practice. The research begins with defining, what is digital manufacturing in architecture, its potentials, components and influences in the contemporary architecture. Further more it discusses the digital fabrication, Two- dimensional cutting, subtractive fabrication, additive fabrication and formative fabrication. The assembly technique, building skin, new materials and mass- customization in digital manufacturing techniques (CAM). That will be a hand in analyzing several case studies.

title	Readiness for the Use of Technology for effective learning via the vds: Case of the United Arab Emirates
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 439-456
summary	Review of the literature indicated that today’s knowledge-driven economy demands a workforce equipped with complex skills and attitudes such as problem solving, meta-cognitive skills, critical thinking and lifelong learning. Such skills can be acquired if learning and teaching are guided by the constructivist and cognitive learning theories. In particular, the constructivist approach emphasises effective learning processes based on learning by doing and collaboration. This approach is congruent with use of technologies, such as Virtual Design Studio (VDS), for the purpose of architecture education in design courses, but such use is lacking in the United Arab Emirates (UAE). It is thus important to assess the extent to which the constructivist and cognitive theories are implemented in teaching design courses in the Architecture schools of the UAE. It is also important to assess the effectiveness of employing technology in general and VDS in particular in implementing these theories. The author intends to study the relationship between effective learning on one hand and using VDS in implementing the constructivist and cognitive approaches on the other hand. Thus, the author conducted a preliminary study to gain a basic understanding of the difficulties, approaches, attitudes, perceptions, and motivation related to the learning of design in architecture schools in the UAE. Second, the investigation was designed to assess the extent to which the students would be interested in the use of sophisticated technology in the teaching and learning environment in the UAE architecture education schools in order to achieve effective learning. The study has been conducted in the United Arab Emirates University (UAEU). Methodology used for this was the focus group method. In addition to the focus group interviews with the UAEU students, unstructured individual interviews with lecturers from UAEU and the American University of Sharjah (AUS) have been carried out. Data analysis showed that students were not satisfied with the current teaching methods based on traditional lectures. It was concluded that students were ready to practice effective learning of design via the intermarriage of VDS and the constructivist and cognitive approaches. An ambiguity that remained was whether students were ready for assessment methods which are consistent with the constructivist approach.

title	BIM and Integrated Practice as Provocateurs of Design Education
doi	https://doi.org/10.52842/conf.caadria.2007.x.l3j
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	Building Information Modeling (BIM) obfuscates the role of composition, scale and abstraction by displacing the primacy of abstract conventions of representation with a methodology based on simulation. BIM subverts, while simultaneously clarifying, the holistic relationships of the parts to the whole in the architectural design of form and space. Architectural design education has great opportunity and risk in how it comes to terms with re-conceptualizing design education pedagogy as the profession struggles to redefine the media and methods of architectural deliverables in the age of BIM. The paper examines the foundation issues proposed by Integrated Practice. The paper questions how BIM and modeled simulation of architectural assemblage might transcend current definitions of convention in design and construction representation. This paper explores how the academy might prepare students of architecture for a digital practice that focuses on the virtual building model and database management. BIM and Integrated Practice viewed as provocateurs of design education provide great potential for critical analysis of how architectural design is taught. The associated pedagogies are transforming the way in which architectural education engages issues of design and representation and creates opportunities to question the roles and rules of traditional conventions. The paper seeks to engage issues of design specificity and ambiguity related to the assets and liabilities of digital modeling as the primary means of design and representation that BIM represents.

title	Detecting Inefficient Lighting Solutions: Step-by-Step Geographic information system (GIS) Technique
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 491-504
summary	Outdoor lighting is used to illuminate roadways, parking lots, yards, sidewalks, public meeting areas, signs, work sites, and buildings. It provides us with better visibility and a sense of security. When well designed and properly installed, outdoor lighting can be and is very useful in improving visibility and safety and a sense of security, while at the same time minimizing energy use and operating costs. But, because nobody thought at this, most street lights shine light not only on the nearby ground, where is needed, but also miles away and skywards. Thus a large fraction of the light is lost, at consumer expense and without his/her consent. In the other hand, shortage in street light may cause more crimes as well as accidents. Most of the wasted or short light comes from the poorly designed street lights. Billboards, decorative lights, poorly shielded security lights are part of the problem too, but the main culprit for the waste and ugly glow one sees above one's head at nights is from the streetlights. Thus, recent computer technology gives us tools to be employed for testing the quality of light. Geographic Information System (GIS) software could be utilized to achieve that mission through applying mapping technique. This technique could analyze digital photographs and define light polluted areas as well as bad lighted. This paper reveals that step by step technique, which employs hybrid technologies to solve such problem for better planning decisions.

title	Developing an Interactive Architectural Meta-System for Contemporary Corporate Environments: An investigation into aspects of creating responsive spatial systems for corporate offices incorporating rule based computation techniques
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 199-212
summary	The research paper exemplifies upon an attempt to create a co-evolving (socio-cultural and technological) programmable spatiality with a strong underpinning in the domain of computation, interaction design and open system typologies for the generation of a constantly informed self-adaptive corporate office space (which addresses the behavioral patterns/preferences of its occupants). Architectural substantiations for such corporate bodies embodying dynamic business eco-systems usually tend to be rather inert in essence and deem to remain closed systemic entities, adhering to a rather static spatial program in accordance with which they were initially conceptualized. The research initiative, rather than creating conventional inert structural shells (hard components), thus focuses upon the development of a meta-system, or in other words the creation of a ‘soft’ computationally enriched open systemic framework (informational) which interfaces with the ‘hard’, material component and the users of the architectural construct (corporate offices). This soft space/meta system serves as a platform for providing the users with a democratic framework, within which they can manifest their own programmatic (activity oriented) combinations in order to create self designed spatial alternatives. The otherwise static/inert hard architectural counterpart, enhanced with contemporary technology thus becomes a physical interface prone to real-time spatial/structural and ambient augmentation to optimally serve its users.

summary	This study aims to analyze relationships of users and spatial configurations using agent-based simulation systems under certain circumstances in a virtual environment with agents that represent users of a shopping mall. Multi-agent simulation methods are used to study emergent behavior patterns. A computer model is generated to simulate user movements in a shopping mall. Today, it is feasible to simulate the movement patterns of human societies at catastrophes like fire and earthquake within the buildings. In this study, exposing the dynamics of user-space relationship will help both students in architectural design education and professionals in practice, to observe and solve design problems before the construction of malls.

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.
