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 comparison of immersive realities and interaction methods: cultural learning in virtual heritage

In recent years, Augmented Reality (AR), Virtual Reality (VR), Augmented Virtuality (AV), and Mixed Reality (MxR) have become popular immersive reality technologies for cultural knowledge dissemination in Virtual Heritage (VH). These technologies have been utilized for enriching museums with a personalized visiting experience and digital content tailored to the historical and cultural context of the museums and heritage sites. Various interaction methods, such as sensor-based, device-based, tangible, collaborative, multimodal, and hybrid interaction methods, have also been employed by these immersive reality technologies to enable interaction with the virtual environments. However, the utilization of these technologies and interaction methods isn’t often supported by a guideline that can assist Cultural Heritage Professionals (CHP) to predetermine their relevance to attain the intended objectives of the VH applications. In this regard, our paper attempts to compare the existing immersive reality technologies and interaction methods against their potential to enhance cultural learning in VH applications. To objectify the comparison, three factors have been borrowed from existing scholarly arguments in the Cultural Heritage (CH) domain. These factors are the technology’s or the interaction method’s potential and/or demonstrated capability to: (1) establish a contextual relationship between users, virtual content, and cultural context, (2) allow collaboration between users, and (3) enable engagement with the cultural context in the virtual environments and the virtual environment itself. Following the comparison, we have also proposed a specific integration of collaborative and multimodal interaction methods into a Mixed Reality (MxR) scenario that can be applied to VH applications that aim at enhancing cultural learning in situ

From Personalization to Adaptivity: Creating Immersive Visits through Interactive Digital Storytelling at the Acropolis Museum

Storytelling has recently become a popular way to guide museum visitors, replacing traditional exhibit-centric descriptions by story-centric cohesive narrations with references to the exhibits and multimedia content. This work presents the fundamental elements of the CHESS project approach, the goal of which is to provide adaptive, personalized, interactive storytelling for museum visits. We shortly present the CHESS project and its background, we detail the proposed storytelling and user models, we describe the provided functionality and we outline the main tools and mechanisms employed. Finally, we present the preliminary results of a recent evaluation study that are informing several directions for future work

Virtual reality tools for the West Digital Conservatory of Archaeological Heritage

International audienceIn the continuation of the 3D data production work made by the WDCAH, the use of virtual reality tools allows archaeologists to carry out analysis and understanding research about their sites. In this paper, we focus on the virtual reality services proposed to archaeologists in the WDCAH, through the example of two archaeological sites, the Temple de Mars in Corseul and the Cairn of Carn Island

Reconciling the dissonance between Historic Preservation and Virtual Reality through a Place-based Virtual Heritage system.

This study explores a problematic disconnect associated with virtual heritage and the immersive 3D computer modeling of cultural heritage. The products of virtual heritage often fail to adhere to long-standing principles and recent international conventions associated with historic preservation, heritage recording, designation, and interpretation. By drawing upon the geographic concepts of space, landscape, and place, along with advances in Geographic Information Systems, first-person serious games, and head-mounted Virtual Reality platforms this study envisions, designs, implements, and evaluates a virtual heritage system that seeks to reconcile the dissonance between Virtual Reality and historic preservation. Finally, the dissertation examines the contributions and future directions of such a Place-based Virtual Heritage system in human geography and historic preservation planning and interpretation
