Keep it simple, keep it smart
At GE Digital, we have worked with selected customers and institutions, such as universities in seven different countries, to identify the main topics that should be considered when designing an HMI screen. We have come up with nine main topics including visual coding, information layout, screen hierarchy and navigation, alarm presentation, and more. These are the rules that we apply when we design our own systems.
Some key takeaways that we’ve learned: Whether it is about the objects used to build the mimics or the colors used for their animation, it’s important keep it simple, readable, and always with the end-user in mind. Avoid 3D objects, shades and bright colors. One word can summarize the overall approach—simplification. And simple design rules can help reduce the time to identify issues and access to the relevant information fast.
The operator should have confidence in the system and be able to recognize and understand information with ease and speed, anticipate and recognize issues quickly, instantly respond, complete the task at hand, and navigate seamlessly. A good operator interface in a production environment means:
- Less training
- Faster reaction
- Less errors and safer operations
- Increased productivity and efficiency
Some of our customers have seen a 5X increase in problem detection and a 37% increase in efficiency when dealing with abnormal situations. And you can, too.
