Augmented reality supports maintenance and repair tasks by overlaying digital information onto the physical environment, aiding technicians in real-time troubleshooting and guidance. By using AR, workers can view 3D models or schematics directly on machinery, enhancing their understanding of complex systems. This technology reduces errors and training time, as technicians can rely on visual aids and step-by-step instructions without referring to manuals. Augmented reality also allows for remote assistance, enabling experienced professionals to guide on-site workers through intricate repairs. Overall, AR enhances efficiency, reduces operational costs, and improves overall service quality in maintenance operations.
