Top 10 Tips for Operator Interface Design
Communicate clearly and configure quickly. Those are the dual goals of human machine interface (HMI) design. Accomplishing those goals depends on the techniques you choose and the tools you use. Here are ten quick tips for making sure your next operator interface project is a success.

1. 
   Color scheme simplicity
   

Lay elements on a screen with a neutral color like gray. Then highlight items that need attention with a bright, bold color, such as yellow, red, or green. The neutral color minimizes distraction when an operator is doing his normal job, and the bright colors help to draw operator attention to extraordinary circumstances.
2. Information simplicity
Don’t crowd the screen with information – place only the information for the current task. Putting more information than is needed on a screen forces operators to search for the one piece of information they need. This could lead to an operator pressing a similar button and making a mistake, or it can increase the time it takes for an operator to figure things out.
3. Consistency
Have a consistent set of menu buttons to help operators navigate easily from screen to screen, and keep them in the same place on each screen. This makes operations simple to understand and eases training.
4. Functional separation
Separate operator screens from maintenance and supervisor screens. When you consider who is using the device most of the day, you can tailor the screens for that user and help him be as efficient as possible. In relation to Tip #2, Information Simplicy, this enables you to create a separate set of screens for a particular user, if appropriate.
5. Test your knowledge
Capture how many times a button is pressed, a page is changed, which page is used most, etc.. Reviewing this data may surprise you. You might find that a piece of information not on the main page is more important than you thought after you review how many times someone goes to a different page to retrieve it. Such a review allows you to fine tune your application and help operators spend less time navigating from screen to screen.
