title	Experimental Applications of Virtual Reality in Design Education

summary	By introducing rapid reproduction, algorithms, and complex formal configurations, the digital era of architecture began a revolution. Architects incorporated the computational capacity of the computer into the design process both as a tool and as a critical component of the theories and practice of architecture as a whole. As we move into what has been coined “the second digital turn,” a period in which digital integration is considered ubiquitous, how can we consider, prepare, and propel towards the next technological innovation to significantly inform design thinking, representation, and manifestation? What tools are available to investigate this speculative design future and how can they be implemented? If the integration of technology in architecture is now a given, perhaps the next digital design era is not just digital but virtual. As new technologies emerge the potential for integrating the virtual design world with our physical senses affords novel possibilities for interactive design, simulation, analysis and construction. Hybrid reality technologies including virtual reality (VR) and augmented reality (AR), embody the potential to supersede conventional representation methodologies such as drawing, rendering, physical modeling, and animation. As they become increasingly pervasive, they will transform how we communicate ideas and data as spatial concepts. Further, they will reform the construct of the built environment when applied to both materiality and fabrication. This paper will describe the incorporation of VR as a tool in various classroom and laboratory settings, recognize the educational outcomes of this incorporation, and identify the potential relationship of these technologies to future academic exploration and application to practice.

title	Inserting and Encircling - Two complementary immersive strategies for mixed-reality applied to cultural heritage *
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 3, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 91-98

summary	To accomplish the aims of a three-year research project we are developing, connected to cultural heritage, we became interested in the fusion of Virtual Reality and Augmented Reality, two emergent development fields that gave birth to what was coined as Mixed Reality. Both dimensions have intricate connections with hardware and software improvements related with the so called "4th Industrial Revolution".Virtual Reality (VR), an interactive experience generated by a computer, takes place inside of simulated environments, which can be analogous to the real world or which can be created as imaginary contexts. On the other hand, Augmented Reality (AR) is always based in an interactive experience inside a tangible environment where the elements of that reality are nurtured with digital information, across several senses, to empathize certain aspects of reality. Our research combines both VR and AR to empathize sensory and intellectual experience. To do so, several senses, mainly visual and auditory, are stimulated.We therefore explore two Case-Studies from our research project in order to show two different strategies. The intention of both situations is to create immersive mixed reality environments where the fusion of the digital and analogue elements can be persistently sustained by the visual outputs.

title	Body Architectures - Real time data visualization and responsive immersive environments
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 2, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 739-746

summary	This project sets up a design framework that promotes augmenting the human body's interactions exploring methods for merging and blending the users of physical and virtual environments, through the design of wearable devices that are embedded with sensors and actuators. This allows for haptic and visual feedback through the use of data that reflects changes in the surrounding physical environment, and visualized in the immersive Virtual Reality (VR) environment. We consider the Body Architectures project to serve as mechanisms for augmenting the body in relation to the virtual architecture. These wearable devices serve to bring a hyper-awareness to our senses, as closed-loop cybernetic systems that utilize 'digitized' biometric and environmental data through the use of 3D scanning technologies and cloud point models, virtual reality visualization, sensing technologies, and actuation. The design of Body Architectures relies on hybrid design, transdisciplinary collaborations, to explore new possibilities for wearable body architectures that evolve human-machine-environment interactions, and create hyper awareness of the temporal, atmospheric qualities that make up our experience of space, as 'sensorial envelopes' (Lally 2014).

title	Church Heritage Multimedia Presentation - Case study of the iconostasis as the characteristic art and architectural element of the Christian Orthodox churches
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 1, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 551-560
doi	https://doi.org/10.52842/conf.ecaade.2019.1.551
summary	This paper is part of ongoing research which aims is to develop the methodology for the church heritage digitization and visualization. The subject of the presented work is the iconostasis, as a significant part of the Christian Orthodox church heritage, distinguished by its bilateral character, as an architectural element of a church interior and an art piece composed of icons. Considering that iconostases can be seen only in situ, we developed the methodology for its digitization and virtual representation dissemination, which provides a user with the possibility to visualize iconostases outside the physical borders of sacral interiors. The proposed methodology relies on techniques for photogrammetric surveying, 3D modeling, and augmented reality visualization, and it is presented in a particular case study of the iconostasis. An outcome is shown as the multimedia presentation of an exhibition, realized throughout collaboration between the university and the museum.

title	Lines, triangles, and nets: A framework for designing input technologies and interaction techniques for computer-aided design
source	International Journal of Architectural Computing vol. 17 - no. 4, 357-381
summary	This article serves to the larger quest for increasing our capacities as designers, researchers, and scholars in understanding and developing human-computer interaction in computer-aided design. The central question is on how to ground the related research work in input technologies and interaction techniques for computer-aided design applications, which primarily focus on technology and implementation, within the actual territories of computer-aided design processes. To discuss that, the article first reviews a collection of research studies and projects that present input technologies and interaction techniques developed as alternative or complimentary to the mouse as used in computer-aided design applications. Based on the mode of interaction, these studies and projects are traced in four categories: hand-mediated systems that involve gesture- and touch-based techniques, multimodal systems that combine various ways of interaction including speech-based techniques, experimental systems such as brain-computer interaction and emotive-based techniques, and explorations in virtual reality- and augmented reality-based systems. The article then critically examines the limitations of these alternative systems related to the ways they have been envisioned, designed, and situated in studies as well as of the two existing research bases in human-computer interaction in which these studies could potentially be grounded and improved. The substance of examination is what is conceptualized as “frameworks of thought”—on variables and interrelations as elements of consideration within these efforts. Building upon the existing frameworks of thought, the final part discusses an alternative as a vehicle for incorporating layers of the material cultures of computer-aided design in designing, analyzing, and evaluating computer-aided design-geared input technologies and interaction techniques. The alternative framework offers the potential to help generate richer questions, considerations, and avenues of investigation.

title	Development of a Semantic Segmentation System for Dynamic Occlusion Handling in Mixed Reality for Landscape Simulation
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 1, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 641-648
doi	https://doi.org/10.52842/conf.ecaade.2019.1.641
summary	The use of mixed reality (MR) for landscape simulation has attracted attention recently. MR can produce a realistic landscape simulation by merging a three-dimensional computer graphic (3DCG) model of a new building on a real space. One challenge with MR that remains to be tackled is occlusion. Properly handling occlusion is important for the understanding of the spatial relationship between physical and virtual objects. When the occlusion targets move or the target's shape changes, depth-based methods using a special camera have been applied for dynamic occlusion handling. However, these methods have a limitation of the distance to obtain depth information and are unsuitable for outdoor landscape simulation. This study focuses on a dynamic occlusion handling method for MR-based landscape simulation. We developed a real-time semantic segmentation system to perform dynamic occlusion handling. We designed this system for use in mobile devices with client-server communication for real-time semantic segmentation processing in mobile devices. Additionally, we used a normal monocular camera for practice use.

title	A shared realities workflow for interactive design using virtual reality and three-dimensional depth sensing
source	International Journal of Architectural Computing vol. 17 - no. 2, 220-235
summary	This article presents the ongoing development and testing of a “shared realities” computational workflow to support iterative user-centered design with an interactive system. The broader aim is to address the challenges associated with observing and recording user interactions within the context of use for improving the performance of an interactive system. A museum installation is used as an initial test bed to validate the following hypothesis: by integrating three- dimensional depth sensing and virtual reality for interaction design and user behavior observations, the shared realities workflow provides an iterative feedback loop that allows for remote observations and recordings for faster and effective decision-making. The methods presented focus on the software development for gestural interaction and user point cloud observations, as well as the integration of virtual reality tools for iterative design of the interface and system performance assessment. Experimental testing demonstrates viability of the shared realities workflow for observing and recording user interaction behaviors and evaluating system performance. Contributions to computational design, technical challenges, and ethical considerations are discussed, as well as directions for future work.

title	Bursting the Bubble
source	ACADIA 19:UBIQUITY AND AUTONOMY [Proceedings of the 39th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-578-59179-7] (The University of Texas at Austin School of Architecture, Austin, Texas 21-26 October, 2019) pp. 310-319
doi	https://doi.org/10.52842/conf.acadia.2019.310
summary	The “bubble" is an oft-used keyword in discussions about Virtual Reality (VR) and Virtual Environments (VE). Apart from pointing to the growing, yet precarious, rise of these domains in technology markets, the “bubble" is also a prolific metaphor for spatial, experiential, and technical aspects of virtual worlds. Combining material from architectural history and history of computing, this paper situates and critically activates two threads of the “bubble" metaphor: the bubble as a closed, autonomous system severed from its surroundings, and the bubble as an ubiquitous, limitless environment. Through historical episodes from the development of Head Mounted Displays (HMDs), the paper positions current VR HDMs into a genealogy of miniaturization of actual architectural “bubbles”— from military simulation domes to wearable “micro environments”—and examines the techniques that support the illusion of these closed, autonomous worlds as limitless and ubiquitous. The paper concludes with the description of a critical design project that exposes the limits of VR's limitless worlds and the role of context (physical, architectural) in both making and breaking the VR bubble.

doi	https://doi.org/10.52842/conf.caadria.2019.2.353
summary	In an increasingly connected world where computers are everywhere, surrounding us in embedded small portable devices, appliances and inside buildings, implementing these interconnected and embedded computers have now become common practice in the design of smart spaces and intelligent environments of today. Digital information is constantly being collected and distributed by a network of digital devices communicating with users and vice versa. New behaviors and activities that may have not been considered before in the design of architectural building types are now commonly found in public and private spaces throughout the world. In an attempt to explore and experiment with the concept of interplay between digital and physical environments, an option studio was proposed to 4th year architecture students to develop a new type of augmented architecture that corresponds to changes in human social behavior due to digital technologies. Five pilot projects are presented with experiments conducted to question three social activities commonly found in everyday lives using Arduino prototypes installed in real physical locations. The prototypes were then used as a basis for the development of large-scale projects proposed as augmented architecture.

summary	In our ever increasing media(ted) world, the robustness of digital communication networked environment is transforming how we relate to our environment. With the rise of the Internet of Things (IOTs) and other ubiquitous mobile communication devices connecting our bodies to our environments, our spaces are requiring a recalibration of the 'well tempered environment'. As technological devices are becoming seamlessly fused with our everyday lifestyles, habits and spaces, articulating experience is one of the most important topics to discuss in human-centered approach to design. This paper presents the initial methods for a data-driven process to enhance human experience as the central motivation. Combining knowledge from neuroscience and experimenting with embodied medias such as Virtual and Augmented Reality (+ MR) , the inquiries into the human dimension is explored in novel ways. The aim is to show how data-driven experiments could be used to assist designers find better performative solutions and that new collaborations between scientist and designers are on the rise as data moves fluidly between bodies and spaces like air in our 21st century.

title	BIM-based Live Sensor Data Visualization using Virtual Reality for Monitoring Indoor Conditions
source	M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 2, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 191-200
doi	https://doi.org/10.52842/conf.caadria.2019.2.191
summary	This paper proposes a method for an automated live sensor data visualization of building indoor environment conditions using a VR system. The proposed method is based on the integration of environmental sensors, BIM, and VR technology. Such integration provides an opportunity to utilize an immersive and live sensing technology for improving data visualization. In our case study, the environmental data, such as indoor air temperature, humidity, and light level are captured by sensors connected to Arduino microcontrollers. The data output of sensors obtained from Arduino units are stored onto the BIM model and transferred to the developed VR system. The developed system simultaneously visualizes numerical values of sensors' reading together with the virtual model of the building in a VR headset. The result of the case study showed that the developed system is capable of visualizing various indoor environmental information of the building with the VR technology. It can provide users with useful information to help monitoring indoor thermal comfort conditions of the building in real-time, while performing the walkthrough in the virtual environment.

summary	Going back in history, the 1st Industrial Revolution occurred between the 18th and 19th centuries, when water and steam power led to the mechanization period. By then, social changes radically transformed cities and, together with manufactured materials like steel and glass, promoted the emergence of new building design typologies like the railway station. In the end of the 19th century, the advent of electrical power triggered mass production systems. This 2nd Revolution affected the building construction industry in many ways, inspiring the birth to the modern movement. For some, standardization emerged as an enemy of arts and crafts, while, for others, it was an opportunity to embrace new design agendas, where construction economy and quality could be controlled in novel ways. More recently, electronics and information technology fostered the 3rd Revolution with the production automation. In architecture, the progressive use of digital design, analysis and fabrication processes started to replace the traditional means of analogical representation. This opened the door for the exploration of a higher degree of design freedom, complexity and customization. The rise of the Internet also changed the way architects communicated and promoted the emergence of global architectural practices in the planet. Today, in the beginning of the 21th century, we are in a moment of profound and accelerated changes in the way we perceive and interact with(in) the world, which many authors, like Klaus Schwab, do not hesitate to call as the Fourth Industrial Revolution. Extraordinary advancements in areas like mobile communication, artificial intelligence, big data, cloud computing, blockchain, nanotechnology, biotechnology, facial recognition, robotics or additive manufacturing are fusing the physical, biological and digital systems of production. Such technological context has triggered a series of disruptive concepts and innovations, like the smart-phone, social networks, online gaming, internet of things, smart materials, interactive environments, personal fabrication, 3D printing, virtual and augmented realities, drones, selfdriving cars or the smart cities, which, all together, are drawing a radically new world.

title	Computational modeling for climate change: Simulating and visualizing a resilient landscape architecture design approach
source	International Journal of Architectural Computing vol. 17 - no. 2, 125-147
summary	Coastlines are changing, wildfires are raging, cities are getting hotter, and spatial designers are charged with the task of designing to mitigate these unknowns. This research examines computational digital workflows to understand and alleviate the impacts of climate change on urban landscapes. The methodology includes two separate simulation and visualization workflows. The first workflow uses an animated particle fluid simulator in combination with geographic information systems data, Photoshop software, and three-dimensional modeling and animation software to simulate erosion and sedimentation patterns, coastal inundation, and sea level rise. The second workflow integrates building information modeling data, computational fluid dynamics simulators, and parameters from EnergyPlus and Landsat to produce typologies and strategies for mitigating urban heat island effects. The effectiveness of these workflows is demonstrated by inserting design prototypes into modeled environments to visualize their success or failure. The result of these efforts is a suite of workflows which have the potential to vastly improve the efficacy with which architects and landscape architects use existing data to address the urgency of climate change.

title	ViBe (Virtual Berlin) - Immersive Interactive 3D Urban Data Visualization - Immersive interactive 3D urban data visualization
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 3, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 83-90
doi	https://doi.org/10.52842/conf.ecaade.2019.3.083
summary	The project investigates the possibility of visualizing open source data in a 3D interactive virtual environment. We propose a new tool, 'ViBe'. We programmed 'ViBe' using Unity for its compatibility with HTC VIVE glasses for virtual reality (VR). ViBe offers an abstract visualization of open source data in a 3D interactive environment. The ViBe environment entails three main topics a) inhabitants, b) environmental factors, and c) land-use; acting as representatives of parameters for cities and urban design. Berlin serves as a case study. The data sets used are divided according to Berlin's twelve administrative districts. The user immerses into the virtual environment where they can choose, using the HTC Vive controllers, which district (or Berlin as a whole) they want information for and which topics they want to be visualized, and they can also teleport back and forth between the different districts. The goal of this project is to represent different urban parameters an abstract simulation where we correlate the corresponding data sets. By experiencing the city through visualized data, ViBe aims to provide the user with a clearer perspective onto the city and the relationship between its urban parameters. ViBe is designed for adults and kids, urban planners, politicians and real estate developers alike.

title	Design variable analysis and generation for performance-based parametric modeling in architecture
source	International Journal of Architectural Computing vol. 17 - no. 1, 36-52
summary	Many architectural designers recognize the potential of parametric models as a worthwhile approach to performance- driven design. A variety of performance simulations are now possible within computational design environments, and the framework of design space exploration allows users to generate and navigate various possibilities while considering both qualitative and quantitative feedback. At the same time, it can be difficult to formulate a parametric design space in a way that leads to compelling solutions and does not limit flexibility. This article proposes and tests the extension of machine learning and data analysis techniques to early problem setup in order to interrogate, modify, relate, transform, and automatically generate design variables for architectural investigations. Through analysis of two case studies involving structure and daylight, this article demonstrates initial workflows for determining variable importance, finding overall control sliders that relate directly to performance and automatically generating meaningful variables for specific typologies.

summary	The usability of virtual reality (VR) controller interfaces are often complex and difficult for first time users. Most controllers provide minimal feedback which relegates the potential for heightened interaction and feedback within virtual experiences. This research explores how haptic technology systems partnered with VR can deliver immersive interactions between user and virtual environment (VE). This research involves the development of a haptic glove interface prototype that incorporates a force feedback and vibrotactile feedback system. It focuses on determining a workflow that communicates in real-time user interaction and environmental feedback using Unreal Engine and the produced haptic glove system. Testing and calibrating the prototype feedback system provided a baseline for developers to rationalise and improve accuracy of current real-time virtual feedback systems. The evaluation of this research in industry unfolds new technical knowledge for implementing a wider range of haptic technologies within VR. This further development would involve reviewing the usability and interaction standards for VR users in the design process.

title	Implementing the Santa Marta Urban Grammar - a pedagogical tool for design computing in architecture

summary	We present a tool intended to enable non-expert users to apply and manipulate a shape grammar, SMUG, which encodes the urban design of informal settlements such as favelas. Such tool, the Interpreter, was developed considering that students would be its main users, and therefore we consider this grammar implementation to potentially be a multipurpose pedagogical tool since it supports conveying knowledge about urban design, shape grammars and parametric modeling using Grasshopper. This paper focuses on the development of the Interpreter and discusses the results of its use in a design studio, which can better inform subsequent iteration as well as other courses and schools.

title	RILAB - architectural envelopes - From spatial representation (generative algorithm) to geometric physical optimization (scientific modeling)

summary	Augmented graphical thinking operates by integrating algorithmic, heuristic, and manufacturing processes. The Representation and Ideation Laboratory (RILAB-2018) exercise begins with the application of a parametric definition developed by the team of teachers, allowing for the construction of structural systems by the means of the combination of segmental shells and bending-active. The main objetive is the construction of a scientific model of simulation for bending-active laminar structures has brought into reality trustworthy previews for architectural envelopes through the interaction of parametrized relational variables. This way we put designers in a strategic role for the building of the pre-analysis models, allowing more preciseness at the time of picking and defining materials, shapes, spaces and technologies and thus minimizing the decisions based solely in the definition of structural typological categories, local tradition or direct experience. The results verify that the strategic integration of models of geometric physical optimization and spatial representation greatly expand the capabilities in the construction of the complex system that operates in the act of projecting architecture.
