Abstract
:The use of augmented reality applied to museums to preserve and communicate cultural heritage sustainably is a topic of increasing relevance today. Museums play an essential role in preserving and disseminating culture and history, and augmented reality has emerged as a powerful technological tool to enrich the visitor experience and ensure the sustainable preservation of cultural heritage. The fundamental objective of this literature review is to explore and understand the key contributions that are being made in the field of augmented reality applied to museums, with a focus on sustainability. The literature related to this topic is dispersed in various sources of information, which motivates the need to carry out a detailed and systematic analysis incorporating sustainability aspects. To carry out this analysis, the metaphor of the “tree of science” is used. This metaphor provides a structured approach that is applied in two complementary ways. Firstly, it focuses on collecting and analyzing scientometric statistics that cover data on countries, authors, academic institutions, and research centers involved in developing augmented reality applications for museums with sustainable methodologies. This quantitative perspective offers a global view of the contributions and their geographical scope including their sustainability impact. Secondly, an evolutionary analysis based on the “tree of science” is carried out. This historical approach examines the origin and evolution of contributions in the field of augmented reality applied to museums, from its first manifestations to the most recent innovations, with an emphasis on sustainable practices. This historical approach is essential to understanding the trajectory and development of augmented reality applications in the museum context and their role in promoting sustainable cultural heritage preservation. This review aims to provide a complete and contextualized view of the use of augmented reality in museums for the sustainable preservation and communication of cultural heritage. Through a multidimensional approach encompassing scientometric statistics and historical analysis, we seek to shed light on this technology’s most significant contributions and evolution in the museum sector, with a particular focus on sustainability.
1. Introduction
The tourism industry, a fundamental pillar of the global economy, has provided employment and sustenance to many. However, this sector has faced unprecedented challenges due to the COVID-19 pandemic, which has generated the need for innovative and sustainable solutions to aid in its recovery during and after the crisis [1]. In this search, information technology has emerged as a crucial component [2]. From interactive web platforms to georeferenced applications, the evolution of technology in tourism has been remarkable [3]. Yet, these advancements have often struggled to provide authentic sustainable and value-added experiences to tourists. Addressing these gaps, augmented reality (AR) has emerged as a disruptive technology, transforming the way users interact with tourist destinations, especially in museums, and the sustainable preservation of cultural heritage.
This article extends its analysis beyond the realm of tourism, recognizing that cultural and natural heritage faces its own unique challenges and opportunities in the digital era, particularly in adopting sustainable practices. Based on an extensive review of the literature and various research reports, we address how emerging technologies are reconfiguring the practices of conservation, management, and communication of heritage, with a focus on sustainability. This review highlights the growing application of hybrid immersive technologies in museums and GeoCities, focusing on their ability to support the sustainable preservation and communication of heritage. We acknowledge the profound transformation that digitalization and immersive technologies are making to the heritage sector, while emphasizing sustainability. Therefore, we integrate case studies, theoretical analysis, and empirical evidence that illustrate how these tools not only improve the accessibility and interpretation of heritage but also raise critical questions about authenticity, sustainability, and inclusion. This multidimensional approach allows for a richer understanding of the complexities associated with digital change in heritage, highlighting both the positive advances and the ethical and practical challenges that arise, particularly those related to sustainable practices.
This literature review delves into various studies on the application of AR in museums and heritage conservation, with a focus on sustainability. A growing body of research has begun to explore this field, indicating a shift towards innovative approaches in heritage communication that are environmentally conscious [4]. Although virtual reality has been a focal point, its accessibility challenges due to technical and hardware requirements are notable [5]. Some studies have also integrated artificial intelligence to enhance the museum experience [6]. However, comprehensive research on how AR can sustainably revolutionize interactions with cultural heritage is still in its infancy. Focusing on how AR applications can support preservation procedures, in addition to communication and enhancement actions, this article aims to bridge this gap with an emphasis on sustainable methodologies. It investigates how AR not only enhances the visitor experience but also plays a crucial role in heritage preservation by enabling interactive and engaging methods to document, display, and interpret historical artifacts and sites in a manner that aligns with sustainable principles. Additionally, the concept of “GeoCities” is defined and explored within this context, particularly how they can contribute to sustainable urban development. “GeoCities” refers to urban areas or cities where geolocation technologies, including AR, are extensively applied to enhance urban experiences, tourism, and heritage conservation. This concept entails the integration of AR into urban landscapes, allowing tourists and locals to interact immersively and informatively with cultural and historical contexts, in an environmentally responsible manner.
In conducting this analysis of the inclusion of hybrid immersive technologies in museums and GeoCities for the preservation and communication of heritage, diverse and significant implications are identified across various academic disciplines, with a perspective on sustainability. In the humanities, these technologies can revolutionize interaction with history, art, and culture by providing more interactive and attractive methods for narration and interpretation, while also considering their environmental impact and promoting sustainable cultural engagement. From an economic perspective, they can significantly influence tourism, creating new attractions and enhancing visitors’ experiences, which could lead to increased revenue for cultural sites and surrounding areas, as well as fostering growth in technological sectors, with an eye on sustainable economic development.
In urban studies and geography, these technologies enable urban planning, historical reconstruction, and cultural preservation, helping to visualize changes and understand urban evolution in a sustainable framework. In sociology and anthropology, they impact how individuals and communities interact with their heritage, democratizing access to cultural experiences but also raising questions about authenticity and cultural representation within sustainable cultural ecosystems. In terms of pedagogy, they transform learning by offering opportunities for experiential and situated learning, making locations and experiences that would be otherwise inaccessible available for study and exploration in an ecologically sensitive manner. In the STEM disciplines, these technologies have specific implications: in science, for simulations and visualizations that are ecologically aware; in technology and engineering, as fundamental fields in the creation and improvement of these technologies with a sustainable approach; and in mathematics, in the development of algorithms that drive immersive experiences while considering environmental sustainability. The integration of hybrid immersive technologies represents a multidisciplinary opportunity with far-reaching implications for sustainable cultural heritage management. They promise increased engagement, democratized access, and innovative educational tools but also present challenges related to authenticity, ethical considerations, and the digital divide within the context of sustainable development. Each discipline can contribute to a holistic understanding and responsible deployment of these technologies, ensuring they serve to enrich and preserve cultural heritage in an inclusive and meaningful way while adhering to sustainability principles.
Employing search equations in academic databases such as WoS and Scopus, this article gathers and analyzes relevant information, with an emphasis on sustainable practices in cultural heritage management. The collected data, after deduplication, is examined through the metaphor of the “tree of science” (ToS), using the Tosr R tool (https://cran.r-project.org/web/packages/tosr/index.html, accessed on 20 September 2023). This scientometric analysis aims to understand the global relevance of this topic and its multiple components, particularly focusing on the sustainable aspects of technological applications in heritage preservation. The review is developed in three parts: The first part describes the methods and key aspects of the “tree of science” used in the research with a sustainable lens. The second part presents an in-depth analysis of the findings, highlighting countries with significant contributions, key authors, and knowledge networks in the context of sustainable development in the heritage sector. The third part, drawing on the metaphor of the “tree of science”, traces the thematic evolution using “root” for foundational elements, “trunk” for thematic development, and “leaves” for emerging trends and directions in the field of AR and its application in museums and GeoCities for heritage preservation and communication while prioritizing sustainability and environmental responsibility.
2. Methods
In the current digital era, the preservation and communication of cultural heritage face new challenges and opportunities, with a focus on sustainability. With the advent of advanced technologies like augmented reality (AR), ‘on-site’ and ‘ex situ’ museums, as well as Geosites, have a unique opportunity to transform the way they present and contextualize both the tangible and intangible elements of cultural heritage in a sustainable manner. AR is not just a tool to visually enhance the display of artifacts and historical narratives, but also a means to emotionally connect visitors with the cultural legacy more deeply and interactively while promoting sustainable practices. In this context, a crucial research question arises: “How can augmented reality transform the presentation and perception of tangible and intangible elements in ‘on-site’ and ‘ex situ’ museums, as well as in Geosites, to enhance and valorize cultural heritage sustainably?” This question seeks not only to explore the potential of AR to enrich the user experience and improve the understanding of cultural heritage in different environments but also to identify and analyze strategies and practices that allow museums and cultural sites to effectively employ this technology to preserve and communicate the richness of cultural heritage to a broader and more diverse audience in an environmentally and culturally sustainable way.
To carry out the analysis focused on the use of disruptive technologies such as augmented reality in the context of cultural heritage preservation in museums through a sustainability lens, we adopted a bibliometric review approach [7]. This approach allowed us to identify and highlight the most significant contributions related to the integration of augmented reality in the museum environment, especially in the new dynamics emerging in the post-pandemic period and their alignment with sustainable practices. We chose to utilize the academic databases WoS and Scopus, renowned for housing a vast collection of peer-reviewed academic documents. Despite the recognition of IEEE and ACM as prominent research databases in computing, we opted to confine our search exclusively to Scopus and WoS. This decision was informed by the extensive time investment required for preprocessing. Additionally, both IEEE and ACM are indexed in Scopus, further justifying our choice to focus on these two databases to ensure a comprehensive understanding of sustainable applications in cultural heritage. For future scientometric research, particularly in the realms of computing and engineering with a sustainable focus, we advocate the inclusion of sources such as IEEE and ACM. These databases are notable for their comprehensive coverage and depth in these specific fields, offering valuable insights and data for more nuanced analysis, including sustainable approaches in heritage technology. The merging of results from both databases, though complex, was executed using specialized tools such as Bibliometrix [8] and the Tosr processing package. This merging process enabled us to obtain a more consensus-based and comprehensive set of results regarding scientific publications related to augmented reality and its influence on the tourism sector, particularly during a period when this sector was heavily impacted by the COVID-19 pandemic and the pressing need for sustainable solutions.
Table 1 details the key variables considered during this literature review. The keywords used included “on-site museum”, “ex situ museum”, “put in value”, “tangible items”, “intangible elements”, “geosites”, “cultural heritage”, and “augmented reality”, as the main search concepts, with a special emphasis on their sustainable integration. The analysis period spanned from 2000 to the present date, resulting in the identification of 1.123 documents in Scopus and 317 in WoS. Subsequently, after the data fusion process, we obtained a consolidated set of 1189 records, eliminating duplicated documents found in both databases. These 1189 articles were distributed across various categories: conference papers (605, or 50.63%), articles (409, or 34.23%), book chapters (71, 5.94%), conference reviews (53, or 4.44%), reviews (37, or 3.1%), early access (5, or 0.42%), books (3, 0.25%), errata (3, 0.25%), editorials (2, or 0.17%), proceedings papers (1, or 0.08%), book reviews (1, 0.08%), corrections (1, 0.08%), editorial material (1, or 0.08%), letter (1, or 0.08%), notes (1, or 0.08%), and retracted (1, or 0.08%). This percentage analysis reflects that most publications are from conference papers and articles, underscoring the relevance and breadth of research on the application of augmented reality in the tourism sector and the preservation of cultural heritage in museums with an increasing focus on sustainable methodologies and practices.
Augmented reality (AR) offers a significant contribution to the sustainable preservation and enhancement of cultural and natural heritage, interacting with key concepts such as “on-site museum”, “ex situ museum”, “put in value”, “tangible items”, “intangible elements”, “geosites”, and “cultural heritage”. In on-site museums, where objects or sites of interest are displayed in their original location, AR provides enriched contexts, enabling virtual reconstructions and interactive narratives that enhance the visitor experience in an environmentally sustainable way. On the other hand, in ex situ museums, where items are displayed outside of their original context, AR can virtually recreate the original setting, helping visitors better understand the significance and environment of the objects while minimizing ecological impact. The phrase “put in value” refers to the process of highlighting the importance of both tangible and intangible heritage elements in a sustainable manner. Here, AR is particularly valuable as it can bring to life intangible aspects such as stories, traditions, and sounds, as well as provide detailed insight into tangible objects with minimal environmental disruption. For instance, in the case of “geosites”, sites of geological significance, AR can reveal historical geological processes and features that are not immediately visible, thus enhancing educational and preservation efforts sustainably.
To carry out the detailed scientometric analysis in this article, two distinct phases were conducted, focusing on the use of augmented reality in museums for the sustainable preservation and communication of cultural heritage. In the first phase, a general overview of the various applications of augmented reality developed in the context of museums and their contribution to the sustainable preservation and communication of cultural heritage was provided. During this stage, the production of documents was analyzed by country, journal, and relevant authors in this field of study. This comprehensive review offers a complete view of the state of production worldwide concerning the application of augmented reality in museums to sustainably preserve and communicate cultural heritage.
The second phase was oriented towards a deeper analysis of the different contributions to this area of knowledge, using the metaphor of the ‘tree of science’ (ToS). Figure 1 presents a detailed representation of the PRISMA scheme, specifying all the stages that were carried out to consolidate the information. To perform the analysis of the collected information, a code developed in R Studio by Core of Science (https://github.com/coreofscience, consulted on 20 September 2023) was utilized. The preprocessing was divided into two parts. The first part involved text mining of Scopus references, as they contain all the important information but in various formats. From this text-mining process, data on authors, years, journals, and titles were extracted. The second part involved web scraping using the DOI found in the WoS references. For this capture, it was necessary to consult the CrossRef app using the DOI to retrieve data on authors, years, titles, and journals. Through this process, the two databases were consolidated, and the result was an Excel file with 22 sheets containing all the detailed information from the combined queries, which is essential for generating scientometric analyses, with a focus on sustainable practices in AR applications.
To generate the ToS, a citation network was constructed from the articles identified in the search and their corresponding references. The SAP algorithm was then employed to categorize the articles into root, trunk, and leaves within this network with an emphasis on highlighting contributions that focused on sustainability in the context of augmented reality in museums. This algorithm mimics the movement of raw and processed sap within a plant, assigning values to root articles and progressing through the tree to the leaves, and then retracing to reassess SAP values, thereby mapping the evolution and impact of sustainable practices in this field. A comprehensive explanation of this methodology is detailed in the work of Valencia-Hernandez et al. [9]. Additionally, the branches of the ToS were delineated using the clustering algorithm developed by Ghosh et al. [10], focusing on the two largest clusters of article nodes and identifying the prevalence and integration of sustainability-oriented research within these clusters.
This code allowed for the extraction of relevant information regarding the results obtained through the search chain, focusing on the specific contributions related to the application of augmented reality in museums to preserve and communicate cultural heritage sustainably. In this way, a structured and comprehensive investigation was conducted, spanning from a general overview of production to a detailed analysis of specific contributions in the field of augmented reality applied to museums. This provides a comprehensive understanding of the role of this technology in the preservation and dissemination of valuable cultural heritage in museums worldwide with a particular focus on how these technologies can be applied sustainably and responsibly.
2.1. Scientometric Analysis: Unraveling the Contribution of Augmented Reality in Museums and Cultural Heritage with Emphasis on Sustainability
To quantitatively delve into the analysis of scientific data, we employ scientometrics, a discipline that allows us to unravel crucial factors in this context. Scientometrics empowers us to identify significant elements, such as author interactions, interwoven citation networks, and the ever-evolving annual production, with a special focus on sustainable practices in these areas. Among the prominent methodologies for conducting this analysis, we find citation-based analysis [11], collaboration network-based analysis [12], and analyses rooted in intellectual structure [13], all of which are now being re-evaluated under the lens of sustainability.
In our endeavor to comprehend the valuable contributions augmented reality brings to the realm of museums and sustainable cultural heritage preservation, our first step was to unveil which countries lead in terms of publications and, consequently, the application of this technology with sustainable implications. Additionally, we delved into the annual evolution of related scientific publications and explored journals that traditionally excel in disseminating advancements in this field while promoting sustainable methods. These assessments were based on the thorough evaluation of consolidated databases such as Scopus and WoS. To achieve a deeper and more comprehensive analysis, we employed the technique of explanatory clusters.
This scientometric analysis provided us with a holistic view of the relevance of augmented reality in the context of museums and cultural heritage preservation, with a particular emphasis on sustainability. By identifying leading geographical areas in research, collaboration patterns among researchers, and publication trends over time, we can appreciate the increasing significance of augmented reality as a transformative tool in the preservation and communication of cultural heritage worldwide in a manner that is both effective and sustainable.
2.2. The Evolution of Knowledge: The Metaphorical “Tree of Science”
The concept of the “tree of science”, commonly known as ToS (tree of science), is based on a metaphorical interpretation that evokes the image of a tree [14]. In this metaphor, articles located at the root represent the theoretical and foundational basis of a developing field of research. As we ascend towards the tree’s trunk, we identify how these research endeavors strengthen and evolve, in the process making significant contributions to the development of the discipline. Finally, the tree’s leaves reveal current trends in application, in this case, where technologies are heading to support and enrich the tourism sector with an added focus on sustainable practices and eco-friendly innovations.
This methodological approach, the “tree of science”, has been widely employed in various fields of knowledge, spanning from economics [15] to education [16], through marketing [17] and many other disciplines. Its applicability lies in its ability to provide a visual and conceptual representation of the evolution of knowledge in a specific area. In our specific context, it allows us to trace the developmental trajectory of augmented reality about museums and cultural heritage preservation, from its theoretical roots to the branches pointing toward new directions of technological application in the tourism domain with an emphasis on sustainable development and eco-conscious methodologies.
The SAP algorithm is a comprehensive multi-step process designed to analyze and structure a subset of academic papers into a directed graph, known as the “tree of science”. It begins by generating a directed graph G from a subset of documents V obtained from WoS and Scopus, where each directed edge represents a citation from one paper to another. This graph is then refined through a series of filtering steps, including selecting the largest connected component, removing loops, eliminating duplicate edges, and discarding vertices with specific criteria for the in-degree and out-degree to form a new graph G’. The algorithm then proceeds to classify the vertices into roots, leaves, and trunks based on their citation relationships and other criteria such as out-degree and in-degree. For example, roots are identified as vertices with an out-degree of zero, and their significance (SAP) is determined by their in-degree. Leaves are vertices with an in-degree of zero, and their importance is assessed based on the number of paths from these leaves to the roots. The trunk classification involves a more complex process, identifying key vertices that act as the main conduits between the roots and leaves of the graph.
Throughout these steps, various functions from the Igraph library are utilized to efficiently select, simplify, and analyze the components of the graph. This includes functions like Graph.clusters(), Graph.simplify(), and Graph.vs.select(), which help in manipulating and refining the graph based on specific parameters. The algorithm constructs the tree of science by creating a subgraph that includes the roots, leaves, and trunk vertices along with their associated edges. This tree represents a structured and hierarchical representation of the academic papers, illustrating the foundational works (roots), emerging topics (leaves), and the pivotal research (trunk) that connects and contextualizes the field.
3. Results
3.1. Scientometric Insights
Figure 2 illustrates the articles produced over the past 22 years, specifically focusing on the application of augmented reality in the tourism sector, with a significant emphasis on museums and cultural heritage and increasingly incorporating sustainable practices and considerations. As depicted in the graph, production has steadily increased. It is worth noting that the initial works, published in 2001, have received the highest number of citations, as they were pioneering contributions in this field, particularly in the context of museums and cultural heritage with early mentions of sustainability. Starting in 2010, the increasing publication trend became evident in both the WoS and Scopus databases, indicating the growing relevance of augmented reality in the preservation and exhibition of cultural heritage within museum environments, with a clear tilt towards sustainable methodologies. The selection of the works for the diferents periods are based on their distinctive and pioneering contribution to the advancement of hybrid immersive technologies in museum and GeoCities contexts with a focus on eco-friendly and sustainable solutions. Each of these studies represents a significant leap in the application and understanding of augmented reality, virtual reality, and mixed reality in cultural and educational realms while addressing sustainability concerns. From technological innovations that enable new ways to explore outdoor archaeological sites in an eco-conscious manner to the development of intuitive interfaces that enhance user interaction and experience with sustainability in mind, these works have marked important milestones in the evolution of the field. They have been selected for their innovative approach to improving user interactivity and participation, as well as their ability to transform education and cultural understanding through immersive experiences while considering environmental impact and sustainability. Additionally, they address critical aspects such as content management, accessibility, and inclusion, demonstrating the potential of these technologies to provide richer and more contextual cultural experiences, and underscoring their relevance in the preservation and communication of heritage in a sustainable context. Furthermore, they have been globally accepted due to the broad number of citations they have received, reflecting their impact in promoting sustainable cultural experiences.
Initial foundational phase (2000–2012): To adequately understand this initial phase, it is essential to highlight the close relationship between the evolution of publications and the advancement of augmented reality technology and its associated devices with an emerging focus on sustainability. During this specific period, a total of 111 publications were produced, with 3301 citations, of which 110 are registered in the Scopus database, while 11 are present in the WoS database. This phase laid the foundations for a field of study that would prove to be of great importance, especially in the context of its application in museums and cultural experiences with a growing consciousness towards sustainable practices. Augmented reality (AR) began its journey towards digital transformation in 1999 with the creation of ARToolkit version 1.0, pioneering software that opened the doors to a new dimension of interaction between the digital and physical worlds while considering the implications for sustainable development. This significant milestone marked the beginning of an era in which technology began to overlay virtual information on the real environment, allowing users not only to observe but also to interact with a digitally enriched space in a more eco-friendly manner. Since then, AR has evolved extraordinarily, being integrated into various sectors such as entertainment, education, and industry, redefining the way we interact with our environment, and expanding the boundaries of our perception, while increasingly incorporating sustainability into its applications; see Table 2.
Initial Development Phase (2013–2018): During this period, publications related to the research topic began to emerge, and although growth was modest initially, it gained greater consistency over time. This phase also began to reflect an increased awareness and incorporation of sustainability in augmented reality applications, particularly in the context of cultural heritage and tourism. A significant increase in the number of publications was observed compared to the initial phase or previous period. In total, 431 publications were identified, representing a substantial number compared to the initial phase. These publications have generated a total of 7923 citations, underscoring the growing importance and interest in the use of augmented reality, especially in the context of applications in museums and cultural heritage, especially in developing sustainable solutions in museums and cultural heritage. This period marked a milestone in the advancement and consolidation of this research area, with a noticeable shift towards incorporating sustainability in augmented reality applications. Throughout this period, several significant contributions of augmented reality to the tourism industry emerged; they are outlined as follows Table 3.
Empowerment Phase (2019–2023): The emergence of COVID-19 has catalyzed the widespread use of various technologies worldwide, and the tourism industry has not been an exception. During this stage, a significant increase in publications related to the use of technologies has been observed, with augmented reality playing a prominent role in this trend while emphasizing sustainable tourism practices. The pandemic forced many people into isolation, leading them to seek new ways to experience tourism and explore places of interest without the need to be physically present. In response, sustainable virtual tourism, supported by augmented reality, emerged as a key solution, enabling eco-friendly access to numerous museums and points of interest worldwide. It was in this context that augmented reality emerged as a key solution, enabling numerous museums and points of interest to be accessible to tourists worldwide, even when they could not visit them physically. This phase also saw advancements in AR technologies focused on reducing carbon footprints and promoting environmental conservation in tourism. During this timeframe, several notable advancements in augmented reality within the tourism sector have surfaced, centered on sustainable and responsible tourism practices, outlined as follows Table 4.

These studies particularly emphasize the sustainable aspect of mixed-reality applications in cultural heritage, such as reducing the wear and tear on physical artifacts and sites. In this ever-evolving research field, these studies highlight the diverse applications of immersive and mixed-reality technologies in the realm of cultural heritage and historical analysis. Marques, Pedro, and Araújo’s article [117] conducts a systematic literature review of gamification in the context of cultural heritage. This review also addresses the sustainable practices in gamifying heritage experiences, reducing the ecological footprint of traditional tourism. Through this review, the authors shed light on how gamification, often involving elements of mixed reality, has been used to enhance visitors’ experiences at cultural and archaeological sites. This study underscores how immersive technologies can be effectively implemented to engage a broader audience and enhance the understanding of historical heritage.
Innocente, Ulrich, Moos, and Vezzetti’s work [118] presents a framework study on the use of immersive XR (extended reality) technologies in the cultural heritage domain. Their study also examines the sustainability of using XR in cultural heritage, such as preserving resources and enhancing digital accessibility. The study provides an overview of how these technologies are being employed in the preservation, documentation, and presentation of cultural sites and objects. Moreover, it emphasizes the importance of an immersive approach to historical analysis, as it can enable researchers and visitors to explore historical environments more deeply and interactively.
Süvari, Okuyucu, Çoban, and Eren Tarakci’s article [119,120,121] focuses on the virtual reconstruction of cultural heritage components that have disappeared using augmented reality technology. The study highlights the role of AR in sustainably reconstructing and preserving lost cultural elements, thereby avoiding the need for physical reconstructions that might affect the sites. This immersive application allows researchers and the public to interact with these lost cultural components and engagedly explore their historical context. Collectively, these studies provide a solid foundation for developing research in the field of immersive and mixed-reality technologies for historical analysis in the context of cultural heritage. They demonstrate how these technologies are being leveraged to enhance visitor experiences, preserve and reconstruct cultural elements sustainably, and enrich our understanding of history and cultural heritage.
The study by Xu, N. [122] and colleagues, focusing on user retention of mobile augmented reality for cultural heritage learning, presented at ISMAR-Adjunct 2022, provides crucial insight into how mobile augmented reality can be used to foster long-term engagement with cultural heritage learning. This research also underscores the sustainability of mobile AR in facilitating widespread access to cultural education, reducing the need for physical travel to historical sites. Meanwhile, Gutkowski, N. et al. [123], in their study on designing historical tours for wearable augmented reality, provide valuable insights into how augmented reality can be used to enrich the experience of historical tours, highlighting the potential of AR in offering sustainable and less intrusive means of exploring historical sites.
The work of Carnevale, L. et al. [124], which explores the use of augmented reality in creating new functions for cultural heritage within an ambient intelligence environment, offers an innovative perspective on how augmented reality can be integrated into museum settings to enhance visitor experience and provide new contexts for historical analysis. Their work also explores the sustainable integration of AR in museums, enhancing visitor experiences without the physical alteration of exhibits. Finally, Zhang, Q. et al. [125] in their study on enhancing the experience of rock painting tours with outdoor augmented reality, presented at ISMAR-Adjunct 2019, contribute a practical application of how augmented reality can be used to enrich the educational experience at historical sites, which is crucial for the development of immersive technologies in the study of heritage. This study also addresses the sustainability of using AR in outdoor settings, offering a non-invasive method to experience and learn about rock paintings without causing damage to these fragile historical artifacts.
5. Conclusions
The application of hybrid immersive technologies, such as augmented reality (AR), in museums and GeoCities has marked a significant advancement in the preservation and communication of cultural heritage. This interdisciplinary field integrates sustainability by offering non-invasive methods to explore and interpret cultural sites, reducing the physical impact on these valuable spaces. This field has profound theoretical and practical implications, inherent challenges, and a promising future research agenda that spans multiple disciplines, including humanities, economics, urban studies, geography, sociology, anthropology, pedagogy, and STEM. The application of augmented reality (AR) in the humanities offers a novel theoretical perspective and practically transforms the visitor’s experience by providing a richer context and deeper connection with cultural heritage. From a sustainability standpoint, AR helps preserve resources and energy by reducing the need for physical infrastructure and travel to cultural sites. From an economic standpoint, AR promises to renew the economic models of museums and historical sites, enhancing tourism and generating new employment and development opportunities, especially in the technological and tourist sectors. Additionally, it offers a sustainable approach to cultural tourism, minimizing ecological footprints while providing economic benefits. In urban studies and geography, AR theoretically changes our understanding of urban space by adding layers of historical and cultural information, and in practice, it has the potential to sustainably revitalize and recontextualize urban spaces, turning them into living canvases of history and culture.
From a sociological and anthropological perspective, AR theoretically challenges and expands our understanding of social and cultural interaction, and in practice, it democratizes access to cultural heritage and promotes a greater intercultural understanding, though it also raises questions about cultural authenticity and representation. In pedagogy, AR offers a sustainable approach to education, reducing the environmental impact associated with traditional learning resources. In the STEM disciplines, AR drives innovation in science and technology, with significant practical implications in fields such as computer science, engineering, and data visualization, requiring the continuous development of advanced software and hardware. This development also includes the challenge of creating environmentally sustainable technology. Collectively, these theoretical and practical implications highlight the transformative potential of AR in the preservation and communication of cultural heritage, paving the way for future research and applications across a variety of fields.
In the realm of applying immersive technologies like augmented reality, some significant limits and challenges must be addressed to ensure the success and integrity of these initiatives. A critical aspect is the sustainable use of technology, ensuring that digital solutions are environmentally friendly and responsibly managed. Ensuring that digital reconstructions are accurate and respect the original context is essential for maintaining the integrity of the cultural heritage that is sought to be preserved and communicated. Achieving this requires close and careful interdisciplinary collaboration among technologists, historians, archaeologists, and other cultural heritage experts, working together to ensure that digital representations are faithful and respectful to the sources. Another significant aspect is the sustainable development of technological accessibility. For immersive experiences to fulfill their potential to educate and enrich a broad audience, they must be accessible to a wide range of the population, including those with economic or physical limitations. This involves not only the availability of the technology itself but also the sustainable design of interfaces and experiences.
The future research agenda in the field of immersive technologies such as augmented reality (AR) presents several key areas that need attention. First, the sustainable development of inclusive technology is crucial. Research is needed on how to make AR and similar technologies more accessible and affordable for various population groups, ensuring that everyone can benefit from these innovations. In addition, assessing the long-term sustainability impact of AR in areas such as heritage education and visitor experience is fundamental. Understanding how these technologies change the way we interact with culture and learning can guide future improvements and should also include a sustainability perspective. Finally, addressing ethical issues related to cultural representation and authenticity in virtual environments is crucial. Ensuring that digital representations are respectful and accurate is vital to maintaining integrity and respect for cultural heritage in the digital age. Together, these areas of research outline a path to a future where immersive technology is used ethically, inclusively, and effectively to enrich our understanding and appreciation of cultural heritage.
