A trainee welds a joint on a jet engine — except the engine isn't real, the sparks are pixels, and a mistake costs nothing but a lesson. Down the hall, a technician looks at a pump through smart glasses and sees glowing arrows showing exactly which bolt to turn next, with the machine's live temperature floating beside it. This is AR and VR in industry , and it is no longer science fiction — it is a core pillar of Industry 4.0 and the emerging Industry 5.0. This guide explains how these immersive technologies are used across industry, and — crucially for students and startups — the best open-source tools you can use to build them for free. Figure 1. AR overlays digital data onto the real world; VR immerses you in a virtual one. Together they form Extended Reality (XR), letting industry visualise machines, data and processes in three dimensions.
