“…The field of AR has experienced a constant evolution in recent years and several surveys of AR [5,20,21] and MAR [22,23] detail the advances in the field. The goal of our project is to disseminate the historical heritage of the city of San Cristóbal de la Laguna in the XVI century using a 3D model of the city in a Location-Based MAR application (LB-MAR) [22].…”

In this paper, we introduce LagunAR, a mobile outdoor Augmented Reality (AR) application for providing heritage information and 3D visualization on a city scale. The LagunAR application was developed to provide historical information about the city of La Laguna in the XVI century, when it was the main city in the Canary Islands. The application provides a reconstructed 3D model of the city at that time that is shown on a mobile phone over-imposed on the actual city using geolocation. The geolocated position is used also for providing information of several points of interest in the city. The paper describes the design and implementation of the application and details the optimization techniques that have been used to manage the full information of the city using a mobile phone as a sensor and visualization tool. We explain the application usability study carried out using a heuristic test; in addition it is probed by users in a qualitative user test developed as preliminary research. Results show that it is possible to develop a real-time application that shows the user a city-scale 3D model and also manages the information of the points of interest.

“…Creating these models must consider various factors, including computational effort related to the detail level needed for the final models-a requirement for augmented Reality. In this scenario, applying orthophotos on geometric models can make graphical representation in mixed realities feasible when dealing with a large volume of data [11,12].…”

“…In addition, data acquisition technologies can become essential components in developing a concise methodology for digitization and application in heritage assets. In the ever-evolving realm of data acquisition technologies, digital photogrammetry, and 3D laser scanning have become indispensable for 3D geometric digitizing and implementing heritage assets [11]. For instance, the creation of point cloud models relies heavily on these tools, which have risen to prominence in cultural 3 of 21 heritage data collection.…”

Amidst the rapid urbanization of cities worldwide, there is a pressing need for practical tools to manage and preserve the invaluable architectural heritage contained within them. This research introduces a systematic methodology for digitalizing and interpreting architectural heritage through augmented Reality (AR). The primary goal is to enhance the documentation, preservation, and accessibility of cultural assets, addressing both educational and touristic needs. Focusing on the historic district of Pelourinho in Salvador, Bahia, Brazil, the study showcases how 3D digitalization combined with AR can provide users with an interactive experience with historical structures, bridging the temporal divide. By integrating the digital replicas of historic buildings into a real-time environment, users gain enriched insights into these structures’ history, architecture, and cultural significance. Though the preliminary results underscore the potential of this approach, comprehensive user testing remains an area for future exploration. This paper thus highlights the potential of AR in historical and cultural preservation, suggesting its broader implications for education, tourism, and heritage management.

“…In recent years, the development of immersive technologies has been remarkable [32,33]. Their adoption, across a wide spectrum of socio-economic life, is expected to increase steadily, especially as we enter the age of virtual worlds and metaverses [34][35][36][37][38][39]. Extended reality (XR) is characterized by augmented reality (AR), virtual reality (VR), and mixed reality (MR).…”

The urgent need for research and study with nondestructive and noninvasive methods and the preservation of cultural heritage led to the development and application of methodologies for the multi-level digitization of cultural elements. Photogrammetry and three-dimensional scanning offer photorealistic and accurate digital representations, while X-rays and computed tomography reveal properties and characteristics of the internal and invisible structure of objects. However, the investigation of and access to these datasets are, in several cases, limited due to the increased computing resources and the special knowledge required for their processing and analysis. The evolution of immersive technologies and the creative industry of video games offers unique user experiences. Game engines are the ideal platform to host the development of easy-to-use applications that combine heterogeneous data while simultaneously integrating immersive and emerging technologies. This article seeks to shed light on how heterogeneous digital representations of 3D imaging and tomography can be harmoniously combined in a virtual space and, through simple interactions, provide holistic knowledge and enhanced experience to end users. This research builds on previous experience concerning the virtual museum for the Antikythera Mechanism and describes a conceptual framework for the design and development of an affordable and easy-to-use display tool for combined representations of heterogeneous datasets in the virtual space. Our solution was validated by 62 users who participated in tests and evaluations. The results show that the proposed methodology met its objectives. Apart from cultural heritage, the specific methodology could be easily extended and adapted for training purposes in a wide field of application, such as in education, health, engineering, industry, and more.
