# Augmented Reality in Cultural Heritage: An Overview of the Last Decade of Applications
## 4 Conclusions
While specific AR gadgets are triggering willingness to use, they are proved to be more suitable in indoor setups rather than outdoor ones. Mobile technology remains one of the most accessible and promising solutions for the user-oriented AR visualization of CH. In order to obtain an effective AR app from the user experience point of view, there are some design considerations that must be addressed. Usability, intuitive visualization of AR content, and the conception of UX interfaces must all be given importance. Enjoyment and usefulness are important aspects regardless of whether we consider the user's freedom to interact through AR technology, where smart glasses are preferred because of the user's free hands and gesture-based implemented metaphors, rather than interaction with mobile multi-touch displays. In addition, the development of an AR app for CH requires knowledge and understanding of cultural and historical aspects. Education has been in the spotlight in the last decade, especially in recent years. Gaining students' attention and maintaining it is particularly difficult in the context of heavy social media and computer or mobile device usage. Recent advances in technology must be exploited to add value to the educational process, and AR, VR, and MR are not exceptions. In cultural heritage-related education tools, AR plays an important role, allowing full immersion in 3D reconstructed historical settings and/or free interaction with virtual reconstructed artifacts. Gamification is combined with AR/VR, ensuring a collaborative and engaging experience, in which learning happens seamlessly. At the same time, through the addition of visual and auditory features to the digital collections, AR increases students' access to CH resources and their understanding. It is hard to find CH experiences outside a tourism-based experience. We cannot imagine holidays without heritage objectives of interest to visit, locally or abroad. AR applications can help tourism by enhancing the visitor's experience and improving CH information perception. By adding 3D visuals to the existing information, AR-based tourism applications can also give tangible advantages by enhancing the value of existing CH attractions. Nevertheless, technology has a long way to go until the tourists will select their cultural heritage objectives as \"have to visit this one\" points of interest on their holiday map, despite the fact that it is mature enough to increase the visual appeal of real artifacts augmented with digital ones and thus trigger strong emotional involvement of the user in a possibly multimodal (visual, audio, textual, intangible) experience. However, tourists are starting to transform from \"simple\" CH content consumers, using mobile accessible devices, to digital heritage contributors, by the means of social media platforms, sharing their CH-oriented experiences and augmenting them with their own stories and memories and thus pushing forward the common cultural memory. Of course, this trend comes with the challenge of filtering this huge amount of information, classifying it, relating it to the existing information, and finally deciding if the visitor's input was useful to humanity's memory. Gamification is intensely exploited in electronic educational resources, especially in the context of online learning. Cultural heritage educational applications make no exception, especially since the AR tools used for developing such solutions allow seamless integration of game-like behavior. Be it a serious game approach to CH or a storytelling approach, application areas for CH education benefit greatly from gamification. User engagement and collaboration, which are crucial for the end results of any educational process, are promoted by incorporating game-related ideas into CH applications. AR and gamification may provide a viable tool to engage participants not only in tangible CH elements, such as artifacts, buildings, and historic sites, but also in intangible CH.
