### RQ6--Who Is the Target Audience of the Published Projects? This analysis reveals a predominance of profiles working within the company (operators, workers, technicians), comprising more than half of the analyzed studies. This predominance can be attributed to these profiles being on the front line of work, often requiring support to facilitate their tasks and reduce cognitive load within the company [99]. Some studies indicate that these profiles collaborate to streamline tasks that were previously complex before the implementation of AR solutions [102]. Also, applications for these entities have been developed to be executed on smartphones or smartglasses [60]. Applications executed on smartglasses are particularly popular among these profiles due to the hands-free condition they offer [48]. Additionally, profiles involved in education (teachers and students) also play a significant role in AR applications within the industry. These applications provide teachers with a powerful tool to create lessons more efficiently, allowing for easier and more effective knowledge transmission [56]. Conversely, students benefit from these applications by experiencing a more intuitive and immersive learning process, bridging the gap between theoretical knowledge and practical skills of traditional training techniques [103]. Another relevant profile is the scientific community, which utilizes these applications for data visualization and experimental event simulation [79]. These applications aim to integrate the customer into the product design phase, creating more personalized products tailored to specific customer needs [98]. Other customer oriented applications add value to traditional experiences by extending their offerings with an AR component [69]. It is also noteworthy that customer-oriented applications are typically executed on smartphones due to the ease of installation and the ubiquity of such devices today [59]. There is one instance of a customer-oriented application executed on a projector, provided by the establishment offering the service [104]. The target audience of AR applications illustrates the transition from the operational focus of Industry 4.0 to the human-centric principles of Industry 5.0. Workers, technicians, and operators remain the primary beneficiaries, as these profiles require task support and cognitive load reduction. Customer-oriented applications directly embody the principle of personalization by integrating users into the product design process and tailoring solutions to individual needs. Additionally, the use of accessible hardware, such as smartphones and tablets, ensures that AR technology can serve diverse audiences effectively. RQ?--Does the Implementation of an Artificial Intelligence System Contribute to the Improvement of Project Functionality? The influence of AI in recent years has gained interest in including an analysis of AI algorithm usage in the reviewed articles. AI has become a widely popular technology across various fields [105]. Also, there has been a notable interest in the use of AI algorithms in AR applications within the industry. Since 2021, applications incorporating this technology have increasingly appeared, and the articles analyzed that have employed AI algorithms date from 2021 onwards, reflecting the growing interest in this tool. A general analysis of the algorithms used reveals that, depending on the objective, Deep Learning or Reinforcement Learning algorithms were employed. Specifically, Deep Learning algorithms were used for various tasks, such as object detection [106], hand gesture recognition [99], anomaly detection in products [107], and voice recognition [100]. In the study utilizing Reinforcement Learning, the algorithm was employed to enhance operators' decision-making processes for maximizing productivity [108], while integrating AI algorithms with augmented reality further improves the efficiency of the application's functionalities [108]. Object tracking for overlaying virtual elements can be improved through this combination of techniques [106].
