The BIM process for the architectural heritage: New communication tools based on AR/VR Case study: Palazzo di Città

The present study aims at presenting the application of the Building Information Modeling methodology to the case study of Palazzo di Città, the Turin City Hall, investigating the possibilities of integration of new technologies in Cultural Heritage preservation and valorization. From the survey phase to the communication of the CH to end-users, BIM methodology, combined with the latest digital innovations (AR, VR, 3d Laser Scanner and much more), allows a fast and highly communicative representation of buildings to both professionals and common visitors who interact with the building life-cycle. An important objective of this work is moreover to demonstrate the advantages of adopting and integrating this technologies in Real Estate Management at a national scale, fully testing the adaptability of parametric software and Virtual Reality modeling to complex and highly decorated buildings, confirming the potentiality of BIM software upon an uncommon field: the historic buildings. The case study is in fact Palazzo di Città, the baroque, seventieth century City Hall of Turin. The research fully meets the latest directives of European Union and other International Organizations in the field of digitization of archives and Public Property management, participating to the international community effort to overcome the contemporary deep Construction Field crisis. In particular, the methodology has been focused and adapted to the protection and management of our huge Heritage, founding its objectives on the quest of cost-saving processes and instruments, applied to the management of a CH. Through BIM it is in fact possible to increase the communication and cooperation among all the actors involved in the building life-cycle behaving as a common working platform. Draws, 3D model and database are shared by all the actors and integrated in the same digital structure, where control tools and cooperation can prevent the designers from errors, saving time and money in the construction phase. The particularity of the case study, Palazzo di Città, being contemporarily a CH, a public asset and a working space, allows a deep study of the possibilities of BIM applied to a complex building, touching very important aspects of a historic building management: digitization of the historic information, publication of modeling techniques of complex architectonical elements, transformations reconstruction, energy consumption control, Facility Management, dissemination, virtual reconstructions of the lost appearance and accessibility for people with sensory and motor impairments. Moreover, the last chapters of the study focus on the fruition of this paramount Turin CH, making available for all kind of people interesting and not well known aspects of the history of the building and of the city itself. This part of the research suggests a methodology to translate static 2d images and written descriptions of a CH into living and immersive VR environment, presenting in an interactive way the transformation of the Marble Hall, once called Aula Maior: the room where the Mayor meets his citizens. Besides the aspects related to the valorization and preservation of the CH, the study reserves considerable space to the deepening of technical aspects involving advanced parametric modeling techniques, use of BIM software and all the vital procedures necessary to the generation of an efficient management informative platform. The whole work is intended as a guide for future works, structuring a replicable protocol to achieve an efficient digitization of papery resources into a 3d virtual model

Integrative Sonic Urbanism: Artist-Led Strategies for Urban Sound Design in the Contemporary City

This doctoral research advances the fields of urban sound design and acoustic planning, presenting new ways of exploring the interrelationship between individual and collective sonic experience, the dynamic potential of the urban sound environment and the complex evolution of the contemporary cityscape. It links urban sound art practices with larger urban design processes, revealing how sound contributes to the production of urban space. The research progresses by crafting a dynamic, integrative methodology that activates contrasting sonic perspectives to critically reassess the role of sound in the public realm. As it discloses this methodology, the research navigates the tension between new modes of urban sound design guided by critical artistic practice and more conventional strategies rooted in the paradigm of environmental noise. Efforts to address urban sonic conditions through quantifiable metrics are contextualised within a wider transition in which urban form is increasingly influenced by data capture, analysis and governance. Within this transition, the critical potential of sound as an active component of urban space is obscured by remedial strategies established to improve what are construed as unfavourable conditions. This research analyses the relationship between these remedial strategies, the emergence of the ISO soundscape standard and the concepts of urban ambiances, urban atmospheres and acoustic territories. It postulates that these centralising conceptual models can serve to limit as well as to advance the critical potential of this field, pursuing instead a more tactical, performative and pluralistic methodology. The articulation of this methodology is substantiated through the exposition of three major public artworks developed by the author, including: Continuous Drift (2015–), a permanent sound installation in a public urban square; The Manual for Acoustic Planning and Urban Sound Design (2013–2020), an artist placement exploring the role of the acoustic planner within a local authority; and The Office for Common Sound (2016–), a project space that fosters dialogue concerning sound within specific regional and institutional contexts. These projects expand the role of artistic practice within the context of urban design and spatial planning by activating the field of urban sound design within diverse spatial, administrative and social contexts. These projects extend established methodologies drawn from sound art, site-specific art and sound installation practices with tactics inherited from public, participatory and socially engaged art, demonstrating how artist-led strategies for urban sound design can advance new forms of spatial production through collaboration with diverse urban actors

Spatial Interaction for Immersive Mixed-Reality Visualizations

Growing amounts of data, both in personal and professional settings, have caused an increased interest in data visualization and visual analytics. Especially for inherently three-dimensional data, immersive technologies such as virtual and augmented reality and advanced, natural interaction techniques have been shown to facilitate data analysis. Furthermore, in such use cases, the physical environment often plays an important role, both by directly influencing the data and by serving as context for the analysis. Therefore, there has been a trend to bring data visualization into new, immersive environments and to make use of the physical surroundings, leading to a surge in mixed-reality visualization research. One of the resulting challenges, however, is the design of user interaction for these often complex systems. In my thesis, I address this challenge by investigating interaction for immersive mixed-reality visualizations regarding three core research questions: 1) What are promising types of immersive mixed-reality visualizations, and how can advanced interaction concepts be applied to them? 2) How does spatial interaction benefit these visualizations and how should such interactions be designed? 3) How can spatial interaction in these immersive environments be analyzed and evaluated? To address the first question, I examine how various visualizations such as 3D node-link diagrams and volume visualizations can be adapted for immersive mixed-reality settings and how they stand to benefit from advanced interaction concepts. For the second question, I study how spatial interaction in particular can help to explore data in mixed reality. There, I look into spatial device interaction in comparison to touch input, the use of additional mobile devices as input controllers, and the potential of transparent interaction panels. Finally, to address the third question, I present my research on how user interaction in immersive mixed-reality environments can be analyzed directly in the original, real-world locations, and how this can provide new insights. Overall, with my research, I contribute interaction and visualization concepts, software prototypes, and findings from several user studies on how spatial interaction techniques can support the exploration of immersive mixed-reality visualizations.Zunehmende Datenmengen, sowohl im privaten als auch im beruflichen Umfeld, führen zu einem zunehmenden Interesse an Datenvisualisierung und visueller Analyse. Insbesondere bei inhärent dreidimensionalen Daten haben sich immersive Technologien wie Virtual und Augmented Reality sowie moderne, natürliche Interaktionstechniken als hilfreich für die Datenanalyse erwiesen. Darüber hinaus spielt in solchen Anwendungsfällen die physische Umgebung oft eine wichtige Rolle, da sie sowohl die Daten direkt beeinflusst als auch als Kontext für die Analyse dient. Daher gibt es einen Trend, die Datenvisualisierung in neue, immersive Umgebungen zu bringen und die physische Umgebung zu nutzen, was zu einem Anstieg der Forschung im Bereich Mixed-Reality-Visualisierung geführt hat. Eine der daraus resultierenden Herausforderungen ist jedoch die Gestaltung der Benutzerinteraktion für diese oft komplexen Systeme. In meiner Dissertation beschäftige ich mich mit dieser Herausforderung, indem ich die Interaktion für immersive Mixed-Reality-Visualisierungen im Hinblick auf drei zentrale Forschungsfragen untersuche: 1) Was sind vielversprechende Arten von immersiven Mixed-Reality-Visualisierungen, und wie können fortschrittliche Interaktionskonzepte auf sie angewendet werden? 2) Wie profitieren diese Visualisierungen von räumlicher Interaktion und wie sollten solche Interaktionen gestaltet werden? 3) Wie kann räumliche Interaktion in diesen immersiven Umgebungen analysiert und ausgewertet werden? Um die erste Frage zu beantworten, untersuche ich, wie verschiedene Visualisierungen wie 3D-Node-Link-Diagramme oder Volumenvisualisierungen für immersive Mixed-Reality-Umgebungen angepasst werden können und wie sie von fortgeschrittenen Interaktionskonzepten profitieren. Für die zweite Frage untersuche ich, wie insbesondere die räumliche Interaktion bei der Exploration von Daten in Mixed Reality helfen kann. Dabei betrachte ich die Interaktion mit räumlichen Geräten im Vergleich zur Touch-Eingabe, die Verwendung zusätzlicher mobiler Geräte als Controller und das Potenzial transparenter Interaktionspanels. Um die dritte Frage zu beantworten, stelle ich schließlich meine Forschung darüber vor, wie Benutzerinteraktion in immersiver Mixed-Reality direkt in der realen Umgebung analysiert werden kann und wie dies neue Erkenntnisse liefern kann. Insgesamt trage ich mit meiner Forschung durch Interaktions- und Visualisierungskonzepte, Software-Prototypen und Ergebnisse aus mehreren Nutzerstudien zu der Frage bei, wie räumliche Interaktionstechniken die Erkundung von immersiven Mixed-Reality-Visualisierungen unterstützen können

Digital 3D Technologies for Humanities Research and Education: An Overview

Digital 3D modelling and visualization technologies have been widely applied to support research in the humanities since the 1980s. Since technological backgrounds, project opportunities, and methodological considerations for application are widely discussed in the literature, one of the next tasks is to validate these techniques within a wider scientific community and establish them in the culture of academic disciplines. This article resulted from a postdoctoral thesis and is intended to provide a comprehensive overview on the use of digital 3D technologies in the humanities with regards to (1) scenarios, user communities, and epistemic challenges; (2) technologies, UX design, and workflows; and (3) framework conditions as legislation, infrastructures, and teaching programs. Although the results are of relevance for 3D modelling in all humanities disciplines, the focus of our studies is on modelling of past architectural and cultural landscape objects via interpretative 3D reconstruction methods
