In recent years augmented reality has begun to be a presence in various industrial sectors. In augmented reality the operator's perception of reality is enriched through virtual information useful to help him in his working activity. Augmented reality can be generated through various technical solutions. A first classification can be made based on how the equipment is used: head mounted displays, handheld displays, and spatial displays. Maintenance can benefit from the introduction of augmented reality as it can help operators in activities characterized by variability and in the risky activities. This is because augmented reality allows to remember the steps of the procedures and highlight the dangers if present. However, the use of augmented reality devices can bring new dangers including ergonomic problems or visual fatigue or information overload. This chapter presents an index methodology for assessing the risks introduced by augmented reality devices.

Mixed Reality

Thanks to the advancement of information technology and the advancement of computing power, it is possible to make the user perceive a different or enriched reality. In addition, to the operator can interact in real time with digitally generated information. These technologies are called Mixed Reality: reality is expanded with virtual information. The Mixed Reality presents a continuous spectra enrichment of reality with virtual information (Milgram et al., 1994). In Figure 1 a graphical representation of Mixed Reality is presented.

Mixed reality spectrum


Virtual Reality stands at one end of the Mixed reality spectrum: here, the user perceives a reality generated by IT systems and can interact with it in real time. Virtual Reality has been used in various areas of work and play: in the workplace, most applications concern training, for example Cha et al (2012) proposed V.R. for firefighter training, Lucas and Thabet (2008) for mine safety training and Lewis et al. (2011) for training in surgical area.

Augmented Reality stands at the opposite side of Mixed Reality.
