ABSTRACT
Operations and maintenance programs traditionally are formulated plans for training, cleaning, work practices and surveillance to maintain equipment and buildings in good condition. The goal is to effectively and efficiently support the life cycle of the facility and its assets. One of the most common applications of industrial Augmented Reality (AR) is assistance to workers in maintenance or repair or control tasks through instructions with textual, visual or auditory information. Such information is rendered ubiquitously, so that the worker perceives the instructions with less effort, thus avoiding the change from a real context to a virtual one where the relevant data are accessed. Remote assistance is a key when companies have machines installed in remote locations. Such machines need to be monitored, operated and repaired with the minimum amount of people on-site. AR involves a set of technologies that make use of an electronic device to view, directly or indirectly, a real-world physical environment that is combined with virtual elements.
