Augmented Reality (AR) is a term that refers to those technologies that incorporate virtual elements in a graphic way to the real world; For its part, Virtual Reality (VR) consists of the integration of elements or objects created artificially but that have a real appearance.

The development of this technology has allowed it to be useful in Industry 4.0, opening up wide possibilities in the maintenance area.

One of the first applications of these technologies was immersive training, taking an important step in technical training. In the same way with augmented reality devices it is possible to obtain information about:

• Process simulation.
• Visualization of labels.
• Remote fault diagnosis.
• Maintenance records.
• Visualization of plans, documents, machinery data, among others.

Virtual and augmented reality in maintenance activities allow technical staff to have access to information about equipment in real time, that is, an augmented reality system, for example, can take data from a machine to project it on a smartphone, tablet or glasses so that an operator has that information while they are working.

Both technologies provide the opportunity for companies in the industrial sector to start the path towards digitization and take advantage of the benefits it brings, such as:

• Improvements in the security issue
• Process improvement
• Costs reduction
• Reduction of waiting times
