The proposed approach aims at providing support through the visualization of different types of information, originating from different organizational levels (Figure 1). In this context, the AR application implements four main functionalities: assembly process information provision, robot motion and workspace visualization, visual alerts and production data. “Multiple visualization” means that tablets and AR glasses can be used in order to support the operator’s work. At any point of time, the user can enable or disable these functionalities, through the interface buttons, with the exception of visual audio alerts that are pushed to his/her device automatically.
