## 3 Augmented Reality in Industry  
Regarding the first stage of data collection, after searching with the terms \"augmented reality\" and \"industry\" (string: \"augmented reality\" and industry), 2157 documents were obtained in the sample. It is important to note that the data presented are based on the Web of Science database and may not represent the entire universe of scientific publications. Figure 2 shows the annual number of publications on augmented reality in industry from 1998 to 2023. In 2022, there was a significant increase in the number of publications compared to 2021, with 425 registered publications. From the presented data, it is possible to observe a clear growth trend in the number of publications in recent years. The data also suggest that research on augmented reality in industry has been an area of increasing interest over the years. Since 2017, the annual number of publications has exceeded the mark of 100 publications, with a substantial increase in 2022. Interestingly, although publications on augmented reality in industry started to be registered in 1998, the annual count of publications remained relatively low until the mid-2010s. From that point on, publications significantly increased each year. Figure 1: Methodological procedures. The data analysis suggests that research on augmented reality in industry is a growing research topic, with increasing interest in exploring its possibilities and applications. This trend can be explained by the increased availability of augmented reality technologies and the recognition of their potential to improve efficiency, productivity, and safety in industry. Regarding the number of publications related to augmented reality in industry in different journals and conference proceedings, the ten titles with the highest number of publications are highlighted (Figure 3). It can be observed that \"Lecture Notes in Computer Science\" obtained the highest number of publications with 78 papers, followed by \"Applied Science Basel\" with 65 articles, and \"Sustainability\" with 47 documents. Other journals and events with a significant number of publications include \"Proceedings of SPIE\" with 42 papers, \"Automation in Construction\" with 34 papers, and \"IEEE Access\" with 32 papers. In addition, it is also possible to identify other significant journals and publications related to augmented reality in industry and gaps in the literature where there are opportunities for further research. The graph showing the ten countries with highest quantity of publications, Figure 4, shows that the United States has the highest number of publications with 342 articles, followed by Germany with 238, China with 188, England with 176, and Italy with 173. The remaining listed countries have fewer than 120 publications each. It should be noted that the sample includes 100 countries, and the top 10 countries with the highest number of publications have been highlighted, emphasizing that this field has global interest with applications in various industrial sectors. This analysis can help identify the significant knowledge-producing countries in the field of augmented reality in industry and indicate possible areas of collaboration among researchers and institutions from different countries.

It can also be helpful for decision making in research and development investment policies in this area. An augmented reality system requires devices that enable the evaluation of the user's position (tracking) and the creation of virtual elements (which can be either geometric or non-geometric models) to integrate them into the environment through display and interaction technologies. Display and interaction technologies are part of a system that uses a set of optical, electronic, and mechanical components to generate images somewhere along the trajectory of human vision, that is, between the observer's eyes and the natural environment [6; 9].
