Studies in the virtual heritage (VH) domain identify collaboration (social interaction), engagement, and a contextual relationship as key elements of interaction design that influence users’ experience and cultural learning in VH applications. The purpose of this study is to validate whether collaboration (social interaction), engaging experience, and a contextual relationship enhance cultural learning in a collaborative and multi-modal mixed reality (MR) heritage environment. To this end, we have designed and implemented a cloud-based collaborative and multi-modal MR application aiming at enhancing user experience and cultural learning in museums. A conceptual model was proposed based on collaboration, engagement, and relationship in the context of MR experience. The MR application was then evaluated at the Western Australian Shipwrecks Museum by experts, archaeologists, and curators from the gallery and the Western Australian Museum. Questionnaire, semi-structured interview, and observation were used to collect data. The results suggest that integrating collaborative and multi-modal interaction methods with MR technology facilitates enhanced cultural learning in VH.

In recent years, considerable efforts have been made by cultural heritage institutions across the globe to digitise cultural heritage sites, artifacts, historical maps, etc. for digital preservation and online representation. On the other hand, ample research projects and studies have been published that demonstrate the great capabilities of web-geographic information systems (web-GIS) for the dissemination and online representation of cultural heritage data. However, cultural heritage data and the associated metadata produced by many cultural heritage institutions are heterogeneous. To make this heterogeneous data more interoperable and structured, an ever-growing number of cultural heritage institutions are adopting linked data principles. Although the cultural heritage domain has already started implementing linked open data concepts to the cultural heritage data, there are not many research articles that present an easy-to-implement, free, and open-source-based web-GIS architecture that integrates 3D digital cultural heritage models with cloud computing and linked open data. Furthermore, the integration of web-GIS technologies with 3D web-based visualisation and linked open data may offer new dimensions of interaction and exploration of digital cultural heritage. To demonstrate the high potential of integration of these technologies, this study presents a novel cloud architecture that attempts to enhance digital cultural heritage exploration by integrating 3D digital cultural heritage models with linked open data from DBpedia and GeoNames platforms using web-GIS technologies. More specifically, a digital interactive map, 3D digital cultural heritage models, and linked open data from DBpedia and GeoNames platforms were integrated into a cloud-based web-GIS architecture. Thus, the users of the architecture can easily interact with the digital map, visualise 3D digital cultural heritage models, and explore linked open data from GeoNames and DBpedia platforms, which offer additional information and context related to the selected cultural heritage site as well as external web resources. The architecture was validated by applying it to specific case studies of Australian cultural heritage and seeking expert feedback on the system, its benefits, and scope for improvement in the near future.

This research project investigates the potential of 360-panorama tours to improve the situated and contextual interpretation, virtual visitation, and spatial understanding of recorded or simulated built heritage sites. Our chosen case study was the Subiaco Hotel, a significant heritage building designed by Summerhayes Architecture, which we documented using 360-degree photographs and linked with other media to create an interactive 360-panorama tour. Today, 360-degree panorama tours such as Google Street View enable the virtual exploration of heritage sites and historic buildings. They demonstrate limited interaction and immersion across a range of platforms and devices, without the requirement of expensive virtual reality headsets, but typically do not integrate other media to leverage spatially richer ways to communicate the historical developments of architectural interiors and exteriors. The primary goals of this study were to establish a comprehensive step-by-step workflow for creating an interactive tour of a significant heritage site, demonstrate how other media such as text, videos, and 3D models can be linked, gather feedback from cultural heritage professionals, and offer future research directions and development guidelines. Apart from detailing an optimized workflow for developing interactive 360-degree virtual tours for heritage buildings, we also offer guidelines for optimal panoramic tour creation and implementation.

Recently, many Resource Description Framework (RDF) data generation tools have been developed to convert geospatial and non-geospatial data into RDF data. Furthermore, there are several interlinking frameworks that find semantically equivalent geospatial resources in related RDF data sources. However, many existing Linked Open Data sources are currently sparsely interlinked. Also, many RDF generation and interlinking frameworks require a solid knowledge of Semantic Web and Geospatial Semantic Web concepts to successfully deploy them. This article comparatively evaluates features and functionality of the current state-of-the-art geospatial RDF generation tools and interlinking frameworks. This evaluation is specifically performed for cultural heritage researchers and professionals who have limited expertise in computer programming. Hence, a set of criteria has been defined to facilitate the selection of tools and frameworks. In addition, the article provides a methodology to generate geospatial cultural heritage RDF data and to interlink it with the related RDF data. This methodology uses a CIDOC Conceptual Reference Model (CRM) ontology and interlinks the RDF data with DBpedia. Although this methodology has been developed for cultural heritage researchers and professionals, it may also be used by other domain professionals.

Applying image processing algorithms to enhance the clarity of underwater images can significantly assist in the visual interpretation of subsea environments. Taking advantage of techniques to maximise the information extracted from the captured input data to produce the highest quality output ensures a higher utilisation of the valuable recorded content which may have been collected at the high cost of a laborious diver survey or an expensive ROV (Remotely Operated Vehicle) expedition. Adopting photogrammetric 3D reconstruction processing in underwater imaging has enabled the creation of high-fidelity digital 3D models which have been used to map subsea infrastructure for maintenance and repair, coral reefs for ecological monitoring, and in the primary context of this article, shipwrecks sites for maritime archaeology and accident investigation. Alongside exploring algorithms to reduce the characteristic haze of underwater photography, this article illustrates the advantages of optimising the processes utilised at distinct stages of the photogrammetric 3D reconstruction workflow to improve the photorealism of the digital 3D models.

This paper examines how 360-degree panoramic tours can enhance heritage promotion, accessibility, and engagement, illustrated through two case studies: the Understory Art and Nature Trail in Northcliffe and the Subiaco Hotel in Perth, Western Australia. The Understory Art Trail was deployed in Google Street View to deliver an interactive, virtual walkthrough of outdoor art installations. This made the site accessible to a geographically diverse global audience, including those unable to visit in person. In contrast, the Subiaco Hotel tour was created with 3DVista. It integrated multimedia features such as historical photographs, architectural drawings, and narrative audio, offering users a layered exploration of built heritage. The two studies were designed so that frameworks like Technology Acceptance Model (TAM) could be applied to them to evaluate visitor experience. However, this paper focuses on the workflow for providing 360-degree panoramic tours, the integration of AR, low-cost digital twins, and the testing of interactive web platforms. Google Street View demonstrates ease of use through familiar navigation, while 3DVista reflects usefulness through its richer interpretive features. By analyzing workflows and digital strategies on both platforms, the study evaluates their effectiveness in increasing online visitor engagement, supporting heritage tourism, and communicating cultural significance. Challenges related to technical limitations, geolocation accuracy, audience targeting, and resource constraints are critically discussed. The findings demonstrate that context-sensitive applications of 360-degree tours are valuable for visibility, education, and long-term preservation. The paper concludes with targeted recommendations to guide future heritage projects in leveraging immersive digital technologies to expand audience engagement and support sustainable heritage management.
