Honest limits

An overlay can be wrong, late, or hard to see. Glare, poor lighting, battery life, network loss, noise, gloves, eye protection, and restricted areas can make a device unsuitable for a task. A worker may also need attention on a moving part, a valve, or another person rather than on a display.

For that reason, a live AR system needs clear boundaries. The procedure must have an accountable source, the worker must be able to pause and question an instruction, and the task must have a safe way to continue or stop when the link fails.

Privacy and security matter too. A live camera feed can reveal equipment, workplaces, or people. The mill needs rules for access, recording, retention, and the use of any remote expert service.

Do not treat an AR label as proof that a step is correct. Test one procedure, define stop conditions, and keep the approved procedure available without the device.
