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	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	Putting the AR in (AR)chitecture - Integrating voice recognition and gesture control for Augmented Reality interaction to enhance design practice
source	M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 1, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 475-484

summary	The architectural design process involves the development of spatial explorable 3D models, but the computer screen is main medium to communicate information to clients. Yet, Augmented Reality (AR) and Virtual Reality (VR) are the closest way to replicate our world, create new ones and interact within them. AR and VR headsets offer different ways to allow multiple stakeholders to effectively immerse themselves in 3D representations of design projects. But, to interact within these spaces and to perform design modifications, the development of new workflows is required. This research presents a new method where AR is used to visualize and edit project models using both voice recognition and hand-gestures software. While numerous projects are addressing software interoperability issues, user-interaction in an AR space remains a developing area of crucial relevance in research. Although hand-gestures are the usual form of model-state control employed in such systems, voice-control is emerging as a highly desirable and everyday form of human-computer interaction. This paper presents a plugin for the Hololens that allows the user to use voice and hand gestures to enhance the ability to work with 3D models and discusses and evaluates the project.

summary	This paper examines a novel, integrated and collaborative approach to design and fabrication, enabled through Mixed Reality. In a bespoke fabrication process, the design is controlled and altered by users in holographic space, through a custom, multi-modal interface. Users input is live-streamed and channeled to 3D modelling environment,on-demand robotic fabrication and AR-guided assembly. The Holographic Interface is aimed at promoting man-machine collaboration. A bespoke pipeline translates hand gestures and audio into CAD and numeric fabrication. This enables non-professional participants engage with a plethora of novel technology. The feasibility of Mixed Reality for architectural workflow was tested through an interactive installation for the makeCity Berlin 2018 festival. Participants experienced with on-demand design, fabrication an AR-guided assembly.

title	Game of Renders - The Use of Game Engines for Architectural Visualization
source	M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 1, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 655-664

summary	Good visualization mechanisms offer architects, and their clients, a better grasp of how their designs are going to turn out when built, and the experience one might have inside the constructions. This also helps the architect orient the design in a more informed manner. However, typically used modeling tools do not offer satisfactory visualization solutions. The operations available to view and navigate through the 3D space are flawed in terms of speed, interactivity, and real-time rendering quality. To solve this issue, we propose the coupling of a portable algorithmic design framework with a Game Engine (GE) to support interactive visualization of architectural models and increase the rendering performance of the framework. We explain in detail this integration, and we evaluate this workflow by implementing a case study and comparing the performance of the GE to architectural modeling tools.

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	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
doi	https://doi.org/10.52842/conf.ecaade.2019.3.091
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.

summary	For the built environment's transformation we are confronted with complex dynamics connected to economic, ecologic and demographic change (Czerkauer-Yamu et al., 2013; Yamu, 2014). In general, cities are complex systems being a "heterogeneous mosaic" of a variety of cultures and functions, characterised by diverging perceptions and interests (ibid). The juxtaposed perceptions and interests in relation to ongoing spatial processes of change create a particularly complex situation. Thus, for planning processes we are in need of approaches that are able to cope not only with the urban complexity but also allow for participatory processes to empower citizens. This paper presents the approach of using Digital Twins in virtual reality (VR) for civic engagement in urban planning, enriched with quantitative and qualitative empirical data as one promising approach to tackle not only the complexity of cities but also involve citizens in the planning process.

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.

summary	Today, architectural models are an important tool for illustrating drawn-on plans or computer-generated virtual models and making them understandable. In addition to the conventional methods for the manufacturing of physical models, a wide range of processes for Direct Digital Manufacturing (DDM) has spread rapidly in recent years. In order to facilitate the application of these new methods for architects, this contribution examines which technical and economic results are possible using 3D printed architectural models. Within a case study, it will be shown on the basis of a multi-storey detached house, which kind of data preparation is necessary. The DDM of architectural models will be demonstrated using two widespread techniques and the resulting costs will be compared.

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.

doi	https://doi.org/10.52842/conf.ecaade.2019.3.107
summary	This essay is related to the research project "The immersive experience in 360°: investigation, representation and digital immersion in the city of Rio de Janeiro in the 19th and 20th centuries", developed at PROURB in FAU-UFRJ, Rio de Janeiro/Brazil. This work will investigate the Panorama of Rio de Janeiro looking for memories and historical truths in its context: Which part represents a historical point of view? Which part is invention? How were the city and its landscape represented on the canvas? As the most well-known Rio de Janeiro's panorama, which project was idealized by the Brazilian painter Victor Meirelles de Lima (1832-1903) and the Belgian photo-painter Henri Charles Langerock (1830-1915), it was exhibited in Brussels 1888, Paris 1889, and Rio de Janeiro 1891-1896, with great recognition in all these cities. This paper will explore this Panorama, its initial studies, its landscape and the architecture depicted, newspapers descriptions of its exhibitions, and mainly, distinguishing among memories, historical truths and verisimilitudes. In order to achieve these objectives, digital and analogical systems of representations, sketches and computer graphics techniques, specially, tridimensional models will be developed and applied.

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	Building Simplification - A fabrication method based on Augmented Reality
source	M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 1, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 495-504
doi	https://doi.org/10.52842/conf.caadria.2019.1.495
summary	Digital design techniques have improved significantly to enable designers to design with fewer limitations. However, the construction methods to fabricate these design proposals are still lagging behind due to a lack of skilled labour, material constraints, and the effects of gravity. Augmented reality has been developed in recent years, and this allows users to impose 3D virtual objects onto the real world. This essay will thus discuss whether augmented reality can guide unskilled labourers to complete complex work, thus overcoming one of the constraints on fabrication for complicated construction. This essay covers the results of three augmented reality tests using a Kinect device, a projector, and Microsoft HoloLens. It aims to show that augmented reality can indeed be used to guide unskilled labourers during construction to narrow the gap between complex design methods and basic construction techniques. The results indicate that augmented reality can guide such fabrication and thus improve construction methods.

summary	To validate the hypothesis that virtual heritage papers are reliant on providing scholarly argumentation based on 3D models, and convenient access is provided to these models where relevant, this study reviewed 264 articles from the last three available proceedings of major digital heritage events and conferences (14 in total). The findings revealed this was not the case, few contain references to accessible 3D models. We discuss why this may be so, and we outline recommendations for ensuring that virtual heritage 3D models can be preserved and accessed.

However, since AR projects virtual models into the real world through portable devices, the designer's review perspective and the number of people able to participate in the review process is limited. Therefore, a system that combines AR and unmanned aerial vehicle (UAV) development with telecommunications technology was designed and prototyped to use the UAV camera as the source of the video stream of AR. This frees the designer's review perspective through ground control and allows remote communication with off-site people, thus allowing more users site access and improving system usability. This paper details the construction of the integrated system, including the integrating of different development languages, environments, and mutual calls used, the AR and UAV development modules, the construction process of the telecommunication protocol, and mutual data interoperability.

summary	In this research, we attempt to develop a tool which integrates certain common geographic information from OpenStreetMap and OpenTopography into Grasshopper. We name it as OSMKIT temporarily. Besides, in order to make the integration in the design process easier, this tool includes the bilateral conversion function of coordinate in Rhinoceros 3D and the coordinate of the World Geodetic System. These characteristics bring about several possibilities for further usage. This paper contains explanations of functions and examples. For instance, it can be employed for data visualization on a map when these data contain coordinate information. Additionally, since this tool is simple and intuitive to convert points into GPS coordinates, it can make users plan drone for photogrammetry and deal with other related tasks on the rhinoceros 3D interface, helping them to gain most current urban models. Moreover, architects or designers can be not only users but also contributors for open source map system such as OpenStreetMap; the process of sharing the mode which user measure is demonstrated in this paper. To sum up, this coordinate system based tool is designed to be multifunctional and suitable for interdisciplinary usages in grasshopper.

title	3D CAD modeling using gestures and speech: Investigating CAD legacy and non-legacy procedures

summary	3D CAD modeling using natural interaction techniques necessitates greater research into the modeling procedures employed by users. In a previously conducted experiment, we elicited speech and gestures input for 3D CAD modeling tasks for conceptual design. In this paper, we examine the 3D modeling procedures articulated by the participants, using gestures and speech, for creating basic 3D models of increasing complexity. We identified 3D modeling procedures and characterized them as CAD legacy and non-legacy procedures. Results show that (1) non-legacy procedures were employed by a considerable number of participants who had fair and high proficiency in CAD and (2) Non-legacy procedures with fewer steps were rated favorably by participants. Based on the results, we provide recommendations on key aspects of non-legacy procedures that need to be incorporated in CAD modeling programs to facilitate speech and gestural input.
