Cover Story (view full-size image): Internet-of-Things applications play a relevant role in today's industry, enabling the sharing of diagnostic data with off-site service teams and the deployment of predictive maintenance systems. Several intervention scenarios, however, still require the presence of a human operator. Augmented reality (AR) and 5G networking allow remote specialists to monitor and guide maintenance operations as if they were in place, as well as improve operators’ safety in dangerous industrial plants by integrating environment-understanding sensors on head-mounted displays. This paper presents a complete setup for assistive maintenance, where AR glasses are equipped with depth and thermal sensors to foresee collisions with dangerous or scorching objects, creating an immersive obstacle detection system along with the real-time interaction with a remote assistant.
