**Title** & **Process** & **AR Description** & **Benefits** & **Limitations** \\ \hline Improving Efficiency of Industrial Maintenance on Augmented Reality [23] & Maintenance & Through the use of AR technology, technicians can access real-time contextualised and visualised information about the specific equipment and components they are requiring or maintaining. This information includes step-by-step guides, animations over-tail on physical devices and relevant equipment data, which facilitates understanding and executing tasks more efficiently. In addition, AR enables better adaptive data management, dynamically adjusting to the specific needs of the end user, contributing to greater accuracy and speed in the execution of maintenance activities. & AR improves maintenance efficiency by providing contextualised and visual information in a significant upfront cost in terms of hardware and software development. \\ \hline Integrated Augmented Augmented Augmented Augmented Augmented Augmented Augmented Augmented Fully Vertual Reality & Training & AR is used in fire training to provide a comprehensive and realistic training experience that combines the real and virtual worlds. Implemented AR uses the VIVE Pro HMD device, which is originally dedicated to VR, but takes advantage of its augmented reality capabilities through its built-in stereo camera. Theworks SDK is used to take advantage of the stereo camera’s capabilities, which include depth perception and approximate object recognition. Artificial intelligence (AI) models are used to recognise detailed information about objects, such as volume and mass, and are used to generate realistic virtual free effects on which operators can be trained, providing them with a more complete and versatile training experience. & Augmented reality provides a safe and controlled training environment where users can practice emergency situations without real risks. & The implementation of augmented reality systems involves a significant upfront cost in terms of hardware and software development. This can be a barrier for companies that are not willing to make a high initial investment. \\ \hline MANTRA: an Effective System Based on Augmented Reality and Infrared Thermography for Industrial Maintenance [50] & Maintenance & MANTRA facilitates faster and fared thermography (IRT) for specific applications in industrial maintenance. MANTRA automates the superimposition of virtual information and temperature data on 3D objects in real time through the joint use of an RGB-D sensor and an IRT camera. This approach ensures high accuracy and robustness in maintenance operations by detecting and estimating the pose of 3D objects with advanced methods such as YOLOv4 for object detection and LINEMOD for pose estimation. & Implementing augmented reality systems such as MANTRA operations and makes it easier to curtain information without requiring technicians to take their eyes off the equipment or reduce they are repairing, which can reduce errors and improve safety. \\ \hline \end{tabular}
