# Augmented Reality's Impact in Industry--A Scoping Review
## 5 Conclusions  
This article presents a scoping review of use of AR applications in Industry X.0. Particular attention is given to their technical aspects and the impact they have had on industrial processes in terms of effectiveness and human-centric innovation. The review highlights the wide range of industrial sectors that have adopted AR solutions, utilizing the technology's capabilities in various ways and employing different strategies to enhance efficiency, personalization, and sustainability. The results indicate a promising future for this technology and its implementation in industry, though further research is necessary to consolidate and optimize these outcomes. Based on this work, the following observations can be made:  
1. The trend in publishing studies on AR applications in industry is on the rise, suggesting that AR is becoming a more standardized and established practice across diverse industrial sectors. The introduction of the Industry 5.0 proposal in 2021 has further driven this trend, encouraging the development of applications that emphasize personalization, sustainability, and human-centric innovation. 2. The arrival of Industry 5.0 has contributed to a growth in publication trends for AR applications. However, the industry has yet to fully adopt the Industry 5.0 concept. While its principles, such as sustainability and human-centric approaches, are being applied, research continues to focus on the Industry 4.0 framework, likely because the term Industry 5.0 is not yet widely used in these types of articles. 3. There is a lack of studies implementing AI algorithms in their AR solutions to enhance the functionalities offered. This indicates a significant gap in the research that could drive further investigation into how AI could improve and expand the capabilities of AR applications, particularly in fostering real-time adaptability and reducing cognitive load for users, key objectives of Industry 5.0. Most of the developed applications are aimed at industrial operators. These applications serve as tools to assist workers, enhancing the efficiency of their tasks while also reducing cognitive load [99]. 5. Applications developed for consumer use are generally designed for handheld devices, as these devices are standardized in society and accessible to everyone, reflecting Industry 5.0's emphasis on inclusivity and accessibility. 6. Some studies involving training or assistance in manual tasks are strongly associated with execution on smartglasses due to their hands-free condition. AR applications predominantly remain in the research domain, with few commercially viable and rigorously evaluated interventions available in real-world settings. This review is particularly useful for developers seeking to understand the current state of AR in industrial contexts and identify opportunities for innovation and improvement. We urge industry stakeholders, including developers, to advance this field by actively participating in the design (e.g., through participatory, iterative, and/or user-centered design processes) and applications (e.g., adopting these services as regular tools) of AR solutions. By incorporating human-centric principles and ensuring that applications address real-world user needs, developers can contribute to the widespread adoption of AR in industrial environments. Strong cooperation between researchers, application developers, and industry professionals is essential to strengthening the scientific evidence of AR, understanding critical success factors, and ultimately achieving widespread acceptance and adoption of AR in industrial ecosystems that prioritize both operational efficiency and human-centric values. This collaboration will help bridge the gap between research and real-world applications, accelerating the impact of AR on the industrial sector.
