summary This paper investigates the integration of mixed reality with parametric modeling. This supports the concept of Form Fostering, which goes beyond the traditional form finding. Form Fostering takes sensory input from the physical world to inform a parametric model. We will present a prototype of the system that we have developed, which includes the use of a Wii Remote, an Arduino processing board, servo actuators and a camera as haptic input and interaction devices for Form Fostering. The potential benefits of designing in mixed reality are significant since designers can get real-time feedback from both the physical context and from changing physical design constraints represented by virtual parametric relationships. In order to leverage seamless interaction and activity between the physical and the virtual world, it is invaluable to consider sensing as an input for design.

title Presence in Virtual Cave

summary Virtual Reality (VR) is usually recognized as a tool that enables the viewer to move freely in a three dimensional digital environment. In this virtual world, different levels of immersion could be reached. Using VR to visualize sites and places from the past, presents and future is widely acknowledged. This study is making use of a recently installed U-Cave theatre at Birzeit University (BZU) in Palestine and a Con-Cave VR theatre at the Norwegian University of Life Sciences (UMB).In the study, we test hypotheses connected to presence in virtual reality environments, using the case of historical sites. Historical sites in general are important for reasons of cultural identification and environmental integrity. In many historical sites, it is difficult for a layperson to read and understand the meaning of the site, for that the remaining ruins don’t provide enough information. This study will contribute to improving the public understanding for historical sites by unfolding the role of Virtual Reality to overcome the harsh reality of many damaged historical sites. The story-line of the site can be easily portrayed by re-constructing the original site in a virtual environment. The study also elaborates on the enriched sense of presence made possible by implementing different levels of details in the VR environment. Presence in VR environments is usually defined as “being there”, with high consideration of the physical ether of the virtual environment, the definition confines attention to the sensation of place. This study calls for expanding the attention to the dimension of time that is made possible by innovative design of VR environment. The study argues that virtual reality technology does not only provide a 3-D experience to subjects, it can also add a fourth dimension by conveying the unconsciousness of man from the meanwhile moment to a different timeframe. Based on the current knowledge on presence in virtual environments, we will use a questionnaire to measure subjective presence for the two VR theatre systems. The study will make use of the following factors in order to determine the degree of presence in the virtual environment: (1) naturalness of interface design and involvement, (2) control and interaction, (3) quality of technical capabilities, and (4) negative effects. The outcome of the study will verify or falsify some of the following hypotheses: • There is a correlation between modeling techniques and presence. The perception of the visual experience differs between traditional media and an immersive VR environment. • A presentation of a historical site in a VR-Cave environment will increase our subject’s awareness of the identity of the historical site. • The presence level is correlated to previous real exposure. Subjects who had been to a ruined historical site in real life, would experience higher level of presence toward the VR presentation than those who had not been to the historical site in reality. • Because of the display enclosure surround effect, it is believed that presence in a Con-Cave would be higher than of U-Cave VR environment.

summary The paper presents an innovative semantic and parametric method to build 3D models to be used in cognitive-information systems. We integrated structured geometrical and documentary information resulting from multiple sources with the aim to enhance the knowledge of those sites within the frame of their historical evolution and their institutional management in a 3D GIS/DB. The developed applications were designed for different types of users, with a largely scalable interface, able to support different output devices and to work at different levels of iconicity. The system allows a full comprehension of the buildings in their own context, permitting to discover unknown relationships, to evaluate their architectural occupancy and to quickly access a complex system of information.

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 work stems from our research on augmented reality (AR); it is focused on the development of AR applications for smartphones. This research was motivated by many factors including the reality that: mobile phones have become commonplace in our societies, there is high demand for access to real - time information, and that smartphones are practical, powerful, and compact devices that are available in developed as well as emerging economies. In light of such facts this work presents a case study and proposes the development of an application capable of linking the most remarkable features of smarthphones (GPS, camera, accelerometer, internet access, and compass).

summary Many buildings around the world have undergone successive changes over their life cycles. Regardless of the type or size of a building there are usually requirements for change due to several unanticipated forces and emerging uncertainties that act upon them. These changes might be in the building’s spatial, structural or service systems. This can be due to changes in the needs of occupants, the market demand or technological advances. Although buildings undergo change, current design practice does not address this and buildings are still designed as if they will remain static. This paper proposes an Adaptable Buildings Design (ABD) Framework to address the issue of adaptability in building design. Using this methodology uncertainties and future changes are first identified. To increase the building’s longevity, flexibility options are embedded and design rules are formulated to trigger these options when necessary. The value of adaptability is then assessed by implementing several simulations using Real Options Analysis (ROA). To demonstrate the approach, the ABD is applied to a multi-use commercial building case study. Flexibility is embedded in the building’s design across several systems allowing it to change and evolve over time based on a set of design rules. The buildings adaptability is then assessed using ROA. Positive results demonstrate the strength of the proposed methodology in addressing future change and uncertaintie.

title Embedded Rationality: A Unified Simulation Framework for Interactive Form Finding
source International Journal of Architectural Computing vol. 8 - no. 4, p. 39
summary This paper describes embedded rationality as a method for implicitly combining fabrication constraints into an interactive framework for conceptual design. While the concept of ‘embedded rationality’ has been previously discussed in the context of a parametric design environment, we employ this concept to present a novel framework for dynamic simulation as a method for interactive form-finding. By identifying categories of computational characteristics, we present a unified physics-solver that generalizes existing simulations through a constraint-based approach. Through several examples we explore conceptual approaches to a fixed form where the resulting effects of interacting forces are produced in real-time. Finally, we provide an example of embedded rationality by examining a constraint-based model of fabrication rationale for a Planar Offset Quad (POQ) panelization system.

title Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call “business views”. We propose a 4 steps-method to compose business views. The first step identifies the users’ business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user’s interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

source FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.623-632
summary This paper demonstrates an ongoing research investigation, which is the continuation of the author’s doctoral research on a computer-based design approach that is used for the generation of circulation diagrams, and the spatial organization of functional areas in macro-scale design level. The paper introduces a computer program that is based on the idea of particle behavior modeling. The program simulates the human movement behavior in real time and in parallel, based on simple rules of interaction between particles. The model is called a ‘virtual force’ model, since the interaction between particles, and hence human movement behavior modeling, is achieved by using various forces that are acting upon each particle. Any changes on the rules of interaction can produce different results, allowing architects to investigate various design possibilities and study the human movement behavior in different design case studies. In this paper the idea of modeling such movement behavior is investigated and developed further, in order for it to be used for the design of circulation systems, and to suggest solutions to problems that occur in public areas of cities.

title Augmented Reality-Based Education and Fire Protection for Traditional Korean Buildings
source International Journal of Architectural Computing vol. 8 - no. 1, 75-91
summary This study examines an application of Augmented Reality technology (AR) for Korean Cultural Traditional Buildings, specifically, the Namdaemun Gate, "National Treasure No 1" of the Republic of Korea. Unfortunately, in February 2008, the Namdaemun Gate burned down, despite the efforts of many firemen, as the main difficulty was getting the fire under control without any structural knowledge of the wooden building. Hence, with the great advances in digital technology, an application of virtual technical information to traditional buildings is needed, and the new technology of AR offers many such advantages for digital architectural design and construction fields. While AR is already being considered as new design approach for architecture, outdoor AR is another practical application that can take advantage of new wearable computer equipment (Head-mounted display also know as HMD, position and orientation sensors, and mobile computing) to superimpose virtual graphics of traditional buildings (in this case, Namdaemun Gate) in a real outdoor scene. Plus, outdoor AR also allows the user to move freely around and inside a 3D virtual construction, thereby offering important training opportunities, for example, specific structural information in the case of firemen and mission planning in the case of a real-life emergency. In this example, the proposed outdoor AR system is expected to provide important educational information on traditional wooden building for architects, archaeologists, and engineers, while also assisting firemen to protect such special buildings.

summary This research introduces the concepts of virtual heritage in the field of architecture. It then continues with the fundamentals of virtual heritage (VH) metadata structure adopted from the UNESCO guidelines. The key highlights to the content of e-Warisan SENIBINA will be demonstrated via techniques to reconstruct heritage buildings towards a collaborative architectural virtual heritage experience as closely to originally design features. The virtual reconstruction will be based on the techniques suggested by the research team tested earlier in a smaller scale of advanced lighting technique for virtual heritage representations. This research will suggest (1) content preparation for creating collaborative architectural heritage, (2) effective low-polygon modelling solutions that incorporate global illumination (GI) lighting for real-time simulation and (3) texturing techniques to accommodate reasonable detailing and give the essence of the VH.

summary Data is ubiquitous in our cities. However, designing a knowledge network about our cities is an arduous task, given that data sensed cannot be used directly, human significance must be added. Adding human significance can be achieved via an automated “expert system (ES)” in which domain expert knowledge are stored in a knowledge-based repository. The domain expert knowledge is matched with the corresponding data to derive specific inference which can aid decision making for urban stakeholders.This requires amalgamation of various interdisciplinary techniques. This paper presents a survey of existing technologies in order to investigate the emerging issues surrounding the design of a live knowledge network for sustainable urban living. The maps and models of the existing infrastructure of our cities that include a wealth of information such as topography, layout, zoning, land use, transportation networks, public facilities, and resource network grids need to be integrated with real-time spatiotemporal information about the city. Public data in forms of archives and data streams as well as online data from the social network and the Web can be analyzed using data mining techniques. The domain experts need to interpret the results of data mining into knowledge that will augment the existing knowledge base and models of our cities. In addition to the analysis of archived and streamed data sources from the built environment, the emerging state-of-the-art Web 2.0 and mobile technologies are presented as the potential techniques to crowddesign a live urban knowledge network. Data modeling, data mining, crowdsourcing, and social intervention techniques are reviewed in this paper with examples from the related work and our own experiments.

summary The hierarchical organization of information is dominant in the setup of tectonic structures. In order to overcome the inherent limitations of these systems, self-organization is proposed as a means for future design. The paper exemplifies this within the research project “Lamel la Flock”. The research takes its point of departure in the structural abilities of the wooden Zollinger system: a traditional structural lamella system distributed as a woven pattern of interconnected beams. Where the original system has a very limited set of achievable geometries our research introduces an understanding of beam elements as autonomous entities with sensorymotor behaviour. By this means freeform structures can be achieved Through computation and methods of self-organization, the project investigates how to design and build with a system based on multiple and circular dependencies. Hereby the agent system negotiates between design intent, tectonic needs, and production. The project demonstrates how real-time interactive modeling can be hybridized with agent–based design strategies and how this environment can be linked to physical production. The use of knowledge embedded into the system as well as the flow of information between dynamic processes, Finite Element Calculation and machinery was key for linking the speculative with the physical.

summary Robotic additive manufacturing has garnered significant research and development interest due to its transformative potential in architecture, engineering, and construction as a cost-effective, material-efficient, and energy-saving fabrication method. However, despite its potential, conventional approaches heavily depend on meticulously optimized work environments, as robotic arms possess limited information regarding their immediate surroundings (Bechthold, 2010; Bechthold & King, 2013). Furthermore, such approaches are often restricted to planar build surfaces and slicing algorithms due to computational and physical practicality, which consequently limits the feasibility of robotic solutions in scenarios involving complex geometries and materials. Building on previous work (Çapunaman et al., 2022), this research investigates conformal 3D printing of clay using a 6 degrees-of-freedom robot arm and a vision-based sensing framework on parametrically reconfigurable tensile hyperbolic paraboloid (hypar) formwork. In this paper, we present the implementation details of the formwork system, share findings from preliminary testing of the proposed workflow, and demonstrate application feasibility through a design exercise that aims to fabricate unique components for a poly-hypar surface structure. The formwork system also offers parametric control over generating complex, non-planar tensile surfaces to be printed on. Within the scope of this workflow, the vision-based sensing framework is employed to generate a digital twin informing iterative tuning of the formwork geometry and conformal toolpath planning on scanned geometries. Additionally, we utilized the augmented fabrication framework to observe and analyze deformations in the printed clay body that occurs during air drying. The proposed workflow, in conjunction with the vision-based sensing framework and the reconfigurable formwork, aims to minimize time and material waste in custom formwork fabrication and printing support materials for complex geometric panels and shell structures.

title Modelos digitales de representación de lo real como estrategia de management alternativo en la práctica profesional arquitectónica [Digital models of representation of reality as an alternative management strategy in architectural practice]
source SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 320-323
summary An architectural project is designed in weeks or months—sometimes in places far from the construction site—and is built in years. The challenge of design is more than creating a three - dimensional digital (3D) model that includes all available information; visualization and communication throughout the entire process is crucial due to the global nature of contemporary architectural practice. This study asks: What tool would satisfy this need for communication? The objective of this paper is to explore these issues and propose an answer to this query based on flexible management to solve them.

summary This paper proposes the use of parametric design software, which is generally used for real-time analysis and evaluation of architectural design variants, to create a new production immanent design tool for robot milling. Robotic constraints are integrated in the data flow of the parametric model for calculating, visualizing and simulating robot milling toolpaths. As a result of the design process, a physical model together with a milling robot control data file is generated.
