A technician stands in front of a gas turbine. The maintenance procedure runs to 200 steps. The expert who wrote it retired last year. This is the situation where an augmented reality application earns its place.
The technician sees the machine and the information attached to it, without looking away.
AR differs from virtual reality (VR), which replaces the environment entirely. Mixed reality (MR) anchors digital objects to the physical world so they respond to spatial movement. In industrial practice, these distinctions matter. VR fits training on rare or dangerous procedures. AR and MR serve the technician on the live machine.
Industry is the most mature environment for AR applications. The reasons are structural: procedures are complex, expertise is scarce, errors carry operational consequences, and the hands-free constraint is non-negotiable.
Retail AR places a sofa in a living room. Industrial AR guides a technician through a hydraulic circuit override at 3 a.m.
