The Person Running It Is Not the Engineer
An installation is usually run day to day by event staff, not the people who built it. If the control screen is cluttered or confusing, small problems become big ones and the supplier gets a call every time something looks odd.
Principles That Help
These are the rules we follow when designing operator screens for our installations.
- Status at a glance — clear green, amber and red indicators
- Few, large controls — start, stop and reset, not a wall of settings
- Plain language — messages that say what to do next
- Confirmation for risky actions — preventing accidental shutdowns
- Logging — a record of events for later review

Think About Real Conditions
Operators may be using a tablet in the dark with one hand, being asked questions by visitors. Buttons should be big, text readable in low light and the most common actions reachable in one tap.
Separate engineer settings from operator controls with a password, so nobody changes calibration by accident.
Test With Real Users
Before launch, ask a person who has never seen the system to run it from the instruction sheet. Every hesitation shows something to fix. Agencies can include that step in a project plan through our partnership service.
