Virtual Exploration of Underwater Archaeological Sites : Visualization and Interaction in Mixed Reality Environments

This paper describes the ongoing developments in Photogrammetry and Mixed Reality for the Venus European project (Virtual ExploratioN of Underwater Sites, http://www.venus-project.eu). The main goal of the project is to provide archaeologists and the general public with virtual and augmented reality tools for exploring and studying deep underwater archaeological sites out of reach of divers. These sites have to be reconstructed in terms of environment (seabed) and content (artifacts) by performing bathymetric and photogrammetric surveys on the real site and matching points between geolocalized pictures. The base idea behind using Mixed Reality techniques is to offer archaeologists and general public new insights on the reconstructed archaeological sites allowing archaeologists to study directly from within the virtual site and allowing the general public to immersively explore a realistic reconstruction of the sites. Both activities are based on the same VR engine but drastically differ in the way they present information. General public activities emphasize the visually and auditory realistic aspect of the reconstruction while archaeologists activities emphasize functional aspects focused on the cargo study rather than realism which leads to the development of two parallel VR demonstrators. This paper will focus on several key points developed for the reconstruction process as well as both VR demonstrators (archaeological and general public) issues. The ?rst developed key point concerns the densi?cation of seabed points obtained through photogrammetry in order to obtain high quality terrain reproduction. The second point concerns the development of the Virtual and Augmented Reality (VR/AR) demonstrators for archaeologists designed to exploit the results of the photogrammetric reconstruction. And the third point concerns the development of the VR demonstrator for general public aimed at creating awareness of both the artifacts that were found and of the process with which they were discovered by recreating the dive process from ship to seabed

Traditional museums, virtual museums. Dissemination role of ICTs.

Molti spazi della cultura, che si configurano come musei di sé stessi, presentano al loro interno pochi reperti esposti. È il caso di musei in edifici o aree archeologiche di seconda fascia, dai quali la maggior parte dei reperti è stata spostata in musei di importanza superiore o dove i reperti sono stati rimossi per diverse esigenze organizzative/espositive. In queste situazioni le ICT permettono di sviluppare un efficace sistema di comunicazione e disseminazione, coinvolgendo i visitatori e gli studiosi mediante l’utilizzo di procedure collegate all’Edutainment, all’interactive ed immersive experience, ai serious games e alla gamification. Come caso studio sono presi il Museo delle Mura, come museo in un edificio, e la Villa di Massenzio, come area archeologica, entrambi collocati sulla Via Appia Antica a Roma. Le esigenze della Sovrintendenza sono di valorizzare e divulgare: - la presenza del Museo, collocato in una delle numerose porte romane ancora ben conservate e site nel giro delle Mura Aureliane; - la storia della porta e del breve tratto di mura ad essa connesse; - la storia e l’articolazione delle mura di Roma. Per la Villa di Massenzio l’obiettivo principale è far comprendere la storia e la funzione delle due strutture (il circo ed il Mausoleo di Romolo), oggi visibili e visitabili, garantendo una maggiore comprensione di un’area di circa 4 ettari, in cui i visitatori oggi possono beneficiare solo di alcuni pannelli informativi.Many cultural spaces, which have been transformed into museums contain very few exhibits. In particular, museums in buildings or second-tier archaeological areas, where most of the finds have been moved to museums of major importance or exhibits that have been removed for different organizational/exhibition needs. In these situations, the use of ICT affords the possibility to incorporate effective communication and dissemination systems. As a result, it involves visitors and scholars within the exhibit using procedures related to edutainment, interactive and immersive experiences, serious games and gamification. As a case study are taken the Museum of the Walls, as a museum in building, and the archaeological area of the Maxentius archaeological complex, as an open-air museum, both located on the Ancient Appia road. In the Museum of the Walls Superintendent's requirements are to enhance and disseminate: - the presence of the Museum, located in one of the many well-preserved Roman city gates located in the Aurelian Walls; - the history of the city gate and of the short section of walls connected to it; - the history and articulation of the walls of Rome. In the Maxentius archaeological the main goal is to make understand the history and the function of the two main structures (the circus and a Mausoleum of Romulus), which are visible and open to visitors, ensuring a greater understanding of an area with the size of about 4 hectares, where visitors today can only benefit information from some panels

A framework study on the use of immersive XR technologies in the cultural heritage domain

Most cultural promotion and dissemination are nowadays performed through the digitization of heritage sites and museums, a necessary requirement to meet the new needs of the public. Augmented Reality (AR), Mixed Reality (MR), and Virtual Reality (VR) have the potential to improve the experience quality and educational effect of these sites by stimulating users’ senses in a more natural and vivid way. In this respect, head-mounted display (HMD) devices allow visitors to enhance the experience of cultural sites by digitizing information and integrating additional virtual cues about cultural artifacts, resulting in a more immersive experience that engages the visitor both physically and emotionally. This study contributes to the development and incorporation of AR, MR, and VR applications in the cultural heritage domain by providing an overview of relevant studies utilizing fully immersive systems, such as headsets and CAVE systems, emphasizing the advantages that they bring when compared to handheld devices. We propose a framework study to identify the key features of headset-based Extended Reality (XR) technologies used in the cultural heritage domain that boost immersion, sense of presence, and agency. Furthermore, we highlight core characteristics that favor the adoption of these systems over more traditional solutions (e.g., handheld devices), as well as unsolved issues that must be addressed to improve the guests’ experience and the appreciation of the cultural heritage. An extensive search of Google Scholar, Scopus, IEEE Xplore, ACM Digital Library, and Wiley Online Library databases was conducted, including papers published from January 2018 to September 2022. To improve review reporting, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used. Sixty-five papers met the inclusion criteria and were classified depending on the study’s purpose: education, entertainment, edutainment, touristic guidance systems, accessibility, visitor profiling, and management. Immersive cultural heritage systems allow visitors to feel completely immersed and present in the virtual environment, providing a stimulating and educational cultural experience that can improve the quality and learning purposes of cultural visits. Nonetheless, the analyzed studies revealed some limitations that must be faced to give a further impulse to the adoption of these technologies in the cultural heritage domain

The Educational Experience of Virtual Reality: An Archaeological Case Study of the Maya Site, Vista Alegre

Archaeological visualization has a long history within the discipline, relying on technological advancements to aid in recording, interpreting, and educating about sites and projects. Though computer graphics have been used as archaeological visualizations for decades, hardware advancements have begun to allow for broader consumer use of Virtual and Augmented Reality platforms in homes, schools, and museums. This thesis explores the applications of Virtual and Augmented Reality platforms for archaeological visualization, specifically in the area of public education. To this end, a 3D model and virtual experience of the Maya site of Vista Alegre in Mexico are created, methodologically explained, and examined to relate history, theory, and the goals of utilizing this medium within the archaeological discipline while expanding on the ethical requirements and empirical methods of praxis. In all, this technology both produces tangible, quantifiable, and accurate data and makes these data more accessible to the general public. Image from Proskouriakoff (1970[1946]

Back in time with immersive heritage tourism experience: A study of virtual reality in archaeological sites

This study focuses on how virtual reality applications might evoke nostalgic sensations in travellers during cultural heritage tourism. While extensive research on the tourism experience has revealed different extrinsic and intrinsic dynamics that affect the tourist experience, this research aims to explore what feeling of back in time VR users experience in an archaeological destination. The gap in visitor experience employing VR research still persists, despite the rising adoption rate of immersive technology, such as virtual reality. In this study, a qualitative method has been applied to analyse online reviews of VR users who visited the Olympia Archaeological Site in Greece and used the ‘Back in Time Olympia’ VR application. The findings drawn from the results show that nostalgia, presence, engagement by learning, and service experience are essential determinants of tourist VR experiences in such cultural heritage destinations

Virtual Community Heritage:An Immersive Approach to Community Heritage

   Our relationship with cultural heritage has been transformed by digital technologies. Opportunities have emerged to preserve and access cultural heritage material while engaging an audience at both regional and global level. Accessibility of technology has enabled audiences to participate in digital heritage curation process. Participatory practices and co-production methodologies have created new relationships between museums and communities, as they are engaged to become active participants in the co-design and co-creation of heritage material. Audiences are more interested in experiences vs services nowadays and museums and heritage organisations have potential to entertain while providing engaging experiences beyond their physical walls. Mixed reality is an emerging method of engagement that has allowed enhanced interaction beyond traditional 3D visualisation models into fully immersive worlds. There is potential to transport audiences to past worlds that enhance their experience and understanding of cultural heritage

Virtual Heritage

Virtual heritage has been explained as virtual reality applied to cultural heritage, but this definition only scratches the surface of the fascinating applications, tools and challenges of this fast-changing interdisciplinary field. This book provides an accessible but concise edited coverage of the main topics, tools and issues in virtual heritage. Leading international scholars have provided chapters to explain current issues in accuracy and precision; challenges in adopting advanced animation techniques; shows how archaeological learning can be developed in Minecraft; they propose mixed reality is conceptual rather than just technical; they explore how useful Linked Open Data can be for art history; explain how accessible photogrammetry can be but also ethical and practical issues for applying at scale; provide insight into how to provide interaction in museums involving the wider public; and describe issues in evaluating virtual heritage projects not often addressed even in scholarly papers. The book will be of particular interest to students and scholars in museum studies, digital archaeology, heritage studies, architectural history and modelling, virtual environments

Theoretical Foundations for Archaeological Pedagogy with Digital 3D, Virtual, Augmented, and Mixed Reality Technologies

Archaeology is inherently a visual and spatial discipline and thus we should strive to center student learning within visual and spatial media. Apart from museum work, site visits, and fieldtrips, the traditional tools of the classroom, however, tend to only convey textual or two-dimensional abstractions of primary archaeological data. The latest digital 3D and eXtended Reality (XR) technologies (Virtual, Augmented, and Mixed) hold the potential for engagement with information in ways that more closely represent the true three-dimensional and visual nature of archaeological objects, spaces, and landscapes. This should allow for an embodied mode of interaction that significantly improves understandings of space and visual content. To maximize these benefits, our deployment of these technologies in the classroom should be guided by formal educational theory and research as well as by prior experiments. Here, we introduce theoretical perspectives on visual and spatial learning, as well as other educational theories, relevant to teaching the humanities and the material past. Our goal is to provide a range of theoretical foundations for pedagogical experiments that involve deploying XR teaching in the archaeological classroom
