Abstract
The article proposes a human-centered conceptual model to integrate Augmented Reality (AR) and Dynamic Digital Models (DDM) to improve training and reduce occupational risks in industrial contexts. A general model integrating DDM and AR to support immersive training and customized and real-time risk management is missing in the literature. The proposed conceptual model was preliminarily validated with company experts in a laboratory environment. According to the expert’s feedback, the system can improve the efficacy of training by means of an immersive environment where users can better perceive hazards and safety-critical situations. Considering the capability of the conceptual model to support real-time and customized risk management, the participating experts argue that the technology seems not to be ready yet, even if it is very interesting and it would be very useful in practice to mitigate occupational risks. Future research activities will consist of the development of a prototypical system based on the presented conceptual model by considering specific user requirements and experts’ feedback.
