# Augmented Reality's Impact in Industry--A Scoping Review
## 4 Discussion
### RQ2--What Areas Within the Industry Do the Published Projects Occupy?  
No single sector dominates, as the relevance of the studies is distributed without any of them standing out notably over the rest. This indicates that the focus is not on any specific industry sector but rather on a widespread general practice.  
However, certain sectors exhibit slightly higher relevance such as the automotive, robotics, education, construction, manufacturing, and logistics sectors.  
In the automotive industry, specific patterns were detected, with most related studies (5 out of 7) targeting industry operators [45; 46; 47; 48; 49]. The solutions presented in automotive applications encompass various purposes, such as education and training [50; 51], information visualization about vehicles [47; 49], and support for maintenance tasks [45].  
The robotics sector also shows significant influence in this review. A clear trend is observed in this sector, with AR solutions exclusively aimed at operators, intending to enhance human-robot interaction [46; 48; 49; 52; 53; 54; 55]. Notably, the operators using these applications are also required to have prior experience in their respective fields. Additionally, smartglasses are frequently used as the execution hardware to allow hands-free operation while using the developed applications, strengthening human-robot interaction and making handling more straightforward and efficient. [46; 48; 49; 54; 55].  
The education sector is another area of higher relevance, with students and educators as the primary target audience and almost exclusive use of smartphones and tablets as execution hardware [50; 51; 56; 57; 58; 59].  
The construction sector also stands out, with AR applications targeting either workers/operators [60; 61; 62; 63] or students/educators [56; 60]. The applications in this sector focus on project visualization and improving worker capabilities [61; 62; 63].  
Manufacturing is also a notable sector, with solutions targeting workers or operators within the industry. Apart from one study aimed at enhancing worker training [64], the other studies focus on improving task precision, facilitating assembly tasks, and enabling real-time quality control [65; 66; 67].  
The logistics sector is prominent among the analyzed studies, with applications supporting inventory tracking and warehouse management. Implementing AR technology improves logistics processes in real time, generating significant efficiency gains [68].  
Tourism also benefits from AR, enhancing tour guides with interactive information and virtual reconstructions that enrich the visitor experience [69].  
The healthcare sector has also embraced AR, particularly in surgical interventions. AR applications enable surgeons to visualize 3D anatomical structures overlaid on the patient, enhancing precision and reducing risks. These applications are valuable for both medical training and preoperative planning, aligning with Industry 5.0 principles by prioritizing patient safety and human-centric innovation [70; 71; 72].  
The widespread implementation of AR technology across numerous sectors demonstrates its adaptability and versatility in addressing diverse industrial needs. While initially aligned with the operational goals of Industry 4.0, such as enhancing efficiency and task visualization for industrial sectors, AR also supports the human-centric principles of Industry 5.0 [73]. Regardless of the specific sector, most AR applications are designed to enhance the interaction between humans and technology, reinforcing AR's role in creating inclusive and adaptable industrial ecosystems.  
Finally, it is essential to mention the studies that did not specify the industry sector where the AR solution is intended to be applied. Once again, it is highlighted that most AR applications within industry are designed for use by workers/operators.  
There is no clear dominance in application purposes or execution hardware, indicating that project requirements dictate the optimal system for achieving the best results.
