Built between 1911 and 1914 by architect Francisco Izidoro Monteiro, the former neoclassical building of the Belo Horizonte School of Medicine (BHSM) was located in a central area of the city. Its design, inspired by the European precepts at the time, was embedded in the same architectural language that characterized the cityscape of the capital of Minas Gerais, Brazil. The original building was gradually dismantled and completely demolished in 1960 to make way for the present headquarters. Few records of its existence remain. In order to contribute to the construction of the digital heritage of the old BHSM building, this paper presents its virtual reconstruction, demonstrates and analyzes the application of Heritage Building Information Modeling (HBIM) for this purpose. Based on data collection and the organization of numerous references (historical photographs, former students' recollections, magazine articles, books, minutes and photogrammetry of the remains), a hypothetical model of the building was developed to represent its condition as built and prior to demolition. Despite the difficulties in modeling, it was possible to perform a virtual historical reconstruction of the building, providing a better understanding of the building that does not currently exist. The preservation of the digital heritage of the demolished building aims to raise public awareness of its memory, which is consistent with the collection of the Memory Center of the UFMG School of Medicine (CEMEMOR).

Cultural institutions are increasingly prioritizing the utilization of diverse mixed reality technologies to enrich the visitor experience during their physical exhibitions. These institutions are actively integrating virtual assets to enhance interactivity and facilitate immersive storytelling experiences. The use of extended reality technologies in cultural heritage dissemination has become a common solution to improve the perception on cultural heritage of their visitors. The objective of the proposed research is to conduct a comparative analysis of three distinct extended reality applications used in cultural heritage experiences. The proposed workflow integrates advanced 3D scanning technology and additive manufacturing techniques to produce tangible replicas which are further enhanced using extended reality technologies, such as Augmented Reality, Desktop Virtual Reality, and Immersive Virtual Reality. To evaluate the developed extended reality applications, we have conducted various System Usability Scale tools to assess applications’ usability while also trying to identify the most appropriate application that can be integrated within the museum exhibition. From a utility point of view we found no notable differences in the user perceptions between proposed solutions, while from a usability and satisfaction point of view, the most preferred solution was the Augmented Reality one. The workflow is presented in sufficient detail to ensure the replication of the results.

Digital reconstruction of ancient buildings is very challenging due to its architectural complexity and structural delicacy. Therefore, how to apply new Earth Observation (EO) technology to digitally reconstruct the complete and real model of ancient buildings without damage has become an urgent issue. This paper proposed a multi-scan point cloud hierarchical registration method for 3D reconstruction of ancient Chinese Great Wild Goose Pagoda based on Terrestrial Laser Scanner (TLS) data. First, a multi-scan point cloud hierarchical registration method is elaborate designed for 3D reconstruction. Then, the outline feature of ancient Chinese Great Wild Goose Pagoda is automatically extracted by point cloud slicing. Finally, fine modeling is carried out according to the outline feature extracted from the reconstructed point cloud, after that block combination and texture mapping are conducted for 3D digitalization and documentation. The experiments indicate that the Root Mean Square Error (RMSE) of multi-scan hierarchical registration of the translation and rotation are less than 3 cm and 0.862° respectively, and the complete and real model of the Great Wild Goose Pagoda is obtained by fine modeling and texture mapping, which provides an important reference for 3D digital protection of ancient buildings.

With increased concerns about data protection and privacy over the past several years, and concomitant introduction of regulations restricting access to personally information (PI), archivists in many jurisdictions now must undertake ‘sensitivity reviews’ of archival documents to determine if they can make those documents accessible to researchers. Such reviews are onerous, given increasing volume of records, and complex, due to how difficult it can be for archivists to identify whether records contain personal information (PI) under the provisions of various laws. Despite research into the application of tools and techniques to automate sensitivity reviews, effective solutions remain elusive. Not yet explored as a solution to the challenge of enabling access to archival holdings subject to privacy restrictions is the application of privacy enhancing technologies (PETs) - a class of emerging technologies that rest on the assumption that a body of documents is confidential or private and must remain so. While seemingly being counter-intuitive to apply PETs to making archives more accessible, we argue that PETs could provide an opportunity to protect PI in archival holdings whilst still enabling research on those holdings. In this paper, to lay a foundation for archival experimentation with use of PETs, we contribute an overview of these technologies based on a scoping review and discuss possible use cases and future research directions.

In this article, we present and discuss a user-study prototype, developed for Bakkehuset historic house museum in Copenhagen. We examine how the prototype - a digital sound installation - can expand visitors’ experiences of the house and offer encounters with immaterial cultural heritage. Historic house museums often hold back on utilizing digital communication tools inside the houses, since a central purpose of this type of museum is to preserve an original environment. Digital communication tools however hold great potential for facilitating rich encounters with cultural heritage and in particular with the immaterial aspects of museum collections and their histories. In this article we present our design steps and choices, aiming at subtly and seamlessly adding a digital dimension to a historic house. Based on qualitative interviews, we evaluate how the sound installation at Bakkehuset is sensed, interpreted, and used by visitors as part of their museum experience. In turn, we shed light on the historic house museum as a distinct design context for designing hybrid visitor experiences and point to the potentials of digital communication tools in this context.
