    In recent years, the development in digital technologies such as Augmented Reality (AR) and Virtual Reality (VR) has evolved rapidly. These technologies are currently in the process of creating driving change in the Cultural and Creative Industries (CCIs), representing innovative means to share information, facilitating access and increasing the value and public awareness on Cultural and Natural Heritage. This is particularly relevant for underwater environments, where the most interesting cultural and naturalistic sites are accessible only to scuba divers, or not accessible at all, due to depth and/or environmental constraints. In addition, in underwater sites, guided diving tours are carried out by professionals that usually describe the area to be visited during the predive briefings; such step is needed due to the impossibility of underwater verbal communication without dedicated equipment, a practice very rarely adopted for recreational diving. So, these difficulties make it almost impossible to replicate under the sea, the guided tour approach that is usually offered in on-land museums. Considering such limitations, several technological applications are emerging to increase the accessibility underwater and enrich users' experience both for divers and nondivers. This work aims to identify the potential of underwater sites (either cultural or natural) to support the development of sustainable tourism (economic, environmental, cultural and social) in the Mediterranean. Moreover, it focuses on supplying local/regional authorities and stakeholders with a multidisciplinary plan for managing Underwater Museums and Knowledge Centres, by promoting innovation in the diving industry and improving users'/tourists' experience through value-added services and cutting-edge technologies

    Making the invisible visible:Underwater Malta—a virtual museum for submerged cultural heritage

    Get PDF
    The seabed can be considered as the world’s largest museum, and underwater sites ex‐ plored and studied so far provide priceless information on human interaction with the sea. In recog‐ nition of the importance of this cultural resource, UNESCO, in its 2001 Convention on the Protection of the Underwater Cultural Heritage, determined that objects/sites should be preserved in situ, whilst also advocating for public access and sharing. The implementation of these principles is not without difficulties. Some states have opened up underwater sites to the public—mainly through diving, yet the vast majority of the world’s population does not dive. In Malta, 7000 years of human occupation is reflected in and on the landscape, and recent offshore surveys show that the islands’ long and complex history has also left an indelible mark on the seabed. Besides difficulties related to their protection and management, these sites also present a challenge with regard to sharing and communicating. Recent advances in underwater imaging and processing software have accelerated the development of 3D photogrammetry of submerged sites and the idea for a virtual museum was born. The virtual museum, UnderwaterMalta, was created out of a need to share the plethora of underwater sites located on the seabed of the Maltese Islands. A multitude of digital tools are used to share and communicate these sites, offering visitors a dry dive into submerged sites that would otherwise remain invisible to the vast majority of the public. This paper discusses the basic principle of the sharing of underwater cultural heritage and the difficulties that beset the implementation of such a principle. A detailed explanation and evaluation of the methods used to gather the raw data needed is set in the context of the particular and unique working conditions related to deep water sites. The workings of this paper are based on first‐hand experiences garnered through the record‐ ing of numerous wrecks over the years and the creation and launch of The Virtual Museum‐Under‐ water Malta—a comprehensive virtual museum specifically built for “displaying” underwater ar‐ chaeological sites that are otherwise invisible to the general public.peer-reviewe

    USING VIRTUAL OR AUGMENTED REALITY for the TIME-BASED STUDY of COMPLEX UNDERWATER ARCHAEOLOGICAL EXCAVATIONS

    International audienceCultural Heritage (CH) resources are partial, heterogeneous, discontinuous, and subject to ongoing updates and revisions. The use of semantic web technologies associated with 3D graphical tools is proposed to improve access, exploration, exploitation and enrichment of these CH data in a standardized and more structured form. This article presents the monitoring work developed for more than ten years on the excavation of the Xlendi site. Around an exceptional shipwreck, the oldest from the Archaic period in the Western Mediterranean, we have set up a unique excavation at a depth of 110m assisted by a rigorous and continuous photogrammetry campaign. All the collected results are modelled by an ontology and visualized with virtual and augmented reality tools that allow a bidirectional link between the proposed graphical representations and the non-graphical archaeological data. It is also important to highlight the development of an innovative 3D mobile app that lets users study and understand the site as well as experience sensations close to those of a diver visiting the site

    Development and integration of digital technologies addressed to raise awareness and access to European underwater cultural heritage. An overview of the H2020 i-MARECULTURE project

    Get PDF
    The Underwater Cultural Heritage (UCH) represents a vast historical and scientific resource that, often, is not accessible to the general public due the environment and depth where it is located. Digital technologies (Virtual Museums, Virtual Guides and Virtual Reconstruction of Cultural Heritage) provide a unique opportunity for digital accessibility to both scholars and general public, interested in having a better grasp of underwater sites and maritime archaeology. This paper presents the architecture and the first results of the Horizon 2020 iMARECULTURE (Advanced VR, iMmersive Serious Games and Augmented REality as Tools to Raise Awareness and Access to European Underwater CULTURal heritage) project that aims to develop and integrate digital technologies for supporting the wide public in acquiring knowledge about UCH. A Virtual Reality (VR) system will be developed to allow users to visit the underwater sites through the use of Head Mounted Displays (HMDs) or digital holographic screens. Two serious games will be implemented for supporting the understanding of the ancient Mediterranean seafaring and the underwater archaeological excavations. An Augmented Reality (AR) system based on an underwater tablet will be developed to serve as virtual guide for divers that visit the underwater archaeological sites

    Editorial for the Special Issue: “3D Virtual Reconstruction for Cultural Heritage”

    The use of 3D modelling, computer-aided design (CAD), augmented reality (AR) and virtual reality (VR) for the acquisition and virtual reconstruction of Cultural Heritage is of great importance in the analysis, study, documentation and dissemination of the past. Reverse engineering (RE) and computer graphics (CG) are also relevant aids for the visualisation and preservation of Cultural Heritage. The integrated use of AR and VR technologies helps to accomplish the full potential of 3D models obtained with reality-based techniques and CAD data, and it aims at interactively communicating the significance of the heritage to non-experts. AR and VR are valid tools for interacting with 3D models and help make culture more accessible to the wider public. Their flexibility can help museum curators to adapt cultural proposals and information about artefacts based on different types of visitor’s categories. These technologies allow visitors to travel through space and time, have fun and get educated on complicated topics. VR/AR technologies are also extremely useful for recreating a lost or hidden environment, leading to a better comprehension of the site or allowing people to discover important sites that are not visible, both for security and conservation reasons

    Underwater Cultural Heritage as an Engine for Social, Economic and Cultural Development. State of Research at the University of Cadiz (Andalusia, Spain)

    Public access to underwater and maritime cultural heritage has proven to have a very positive effect on the local economy. This type of heritage is very attractive for the cultural tourism sector in general and for active and diving tourism. The Nautical and Underwater Archeology Line of the University of Cadiz, within the framework of the TIDE Project (Interreg Atlantic Area) and Herakles Project (FEDER-UCA18-107327) have been working on the enhancement of maritime and underwater heritage through the application of new technologies. In this paper, we will present the advances in the project in the Strait of Gibraltar, based on the first phase of scientific analysis and on the definition of a common working methodology that has resulted in a toolkit for the development of tourism activities linked to the MCH and UCH. Pilot activities under development are focused on accessible underwater heritage routes, VR applications to create Dry Dive experiences and the streaming of underwater archaeological works, thanks to a bottom-surface acoustic communication buoy. Results show that these types of outreach solutions and, by extension, of tourism application, must be preceded by a rigorous archaeological research process, a study of the target audience and the evaluation of the carrying capacity of the sites, to avoid falling into the mercantilisation or deterioration of the UCH. On the other hand, virtual or indirect access solutions are very useful, but always through the correct interpretation of the heritage.This research was funded by TIDE, or Atlantic Network for Developing HistoricalMaritime Tourism; EAPA_630/2018 is an Interreg funded project.
