Smart glasses function in industrial applications by providing real-time data and augmented reality overlays that enhance worker efficiency and safety. These devices enable workers to access instructions, checklists, and visual aids hands-free, allowing them to maintain focus on their tasks. Additionally, smart glasses can facilitate remote assistance through video streaming, enabling specialists to guide on-site personnel without needing to be physically present. This integration of technology helps reduce errors, improve training, and ultimately leads to increased productivity in industrial settings.
