Smart factories are becoming more and more common and Augmented Reality (AR) is a pillar of the transition to Industry 4.0 and smart manufacturing. AR can improve many industrial processes such as training, maintenance, assembly, quality control, remote collaboration and others. AR has the potential to revolutionize the way information is accessed, used and exchanged, extending user’s perception and improving their performance. This work proposes a Pervasive AR tool, created in collaboration with industrial partners, to support the training of operators on industrial shop floors while performing production operations. A Human-Centered Design (HCD) methodology was used to identify operators’ difficulties, challenges, and define requirements. After initial meetings with stakeholders, an AR prototype was designed and developed to allow the configuration and visualization of AR content on the shop floor. Several meetings and user studies were conducted to evaluate the developed tools and improve their usability and features. Comparisons between the proposed Head Mounted Display (HMD) solution, the method currently being used in the shopfloor and alternative AR solutions (mobile based) were conducted. The results of user studies suggest that the proposed AR system can significantly improve the performance (up to 70% when compared with the method currently used in the shop floor) of novice operators.
