In the field of maintenance in particular, the use of data glasses (smart glasses) is becoming increasingly important. Smart glasses to assist with certain maintenance activities are not only technically feasible but already possible today. The overlapping of virtual components and real life environment allows a wide range of uses in the manufacturing sphere. Thanks to flexible information acquisition and management, the work performed becomes more accurate, efficient, interactive and simple. Our objective is to use this technology in industrial maintenance, inspection and repairs to ensure the maximum possible quality and efficiency of the service provided by our specialist personnel.
