Pete Wassell discusses how augmented reality smart glasses and the industrial internet of things can improve industrial operations. Industry 4.0 leverages cyber-physical systems like sensors and big data analytics to improve communication between machines and workers. This allows workers to get predictive maintenance alerts and inspection guidance to increase efficiency. Implementing AR smart glasses can boost productivity by 25% in warehouses and reduce error rates by 44% in assembly. The global market for industrial IoT is estimated to reach $110 billion by 2020 and $123 billion by 2021, improving productivity and savings opportunities for companies.
