The difficulty in creating a truly advanced HMI is putting yourself in the shoes of the person using the screen.
When it comes to systems that control different machines, an experienced HMI programmer will take into account the operator's limited knowledge, creating navigation menus that are easy to follow and allow users to quickly navigate to key elements.
In addition, the flow of the system will be consistent and kept private with details that will allow users to more easily understand their way around the HMI. Finally, the design of the system should be sufficient to simulate a real system so that users can comfortably use the interface without having to access additional information. This may include appropriate names for machines on the floor, easy-to-understand icons, and symbols that accurately represent plant assets.
