Arranging the Screen To allow rapid access, with no confusion, group controls and parts of the display logically. A good method is to design in black and white, using grouping and spacing to enforce clarity, then add colour where it will help the operator. You could group related items by drawing a box around them. Make sure your design is simple, logically organised and well labelled. Display only necessary information and avoid cluttering the screen with data that is irrelevant to the user - involve the operator early in the design process.
Some displays let people jump to a completely different screen.
In this case make sure you include an obvious a way back. For example, it's easy to misread text but you can instantly get a rough idea of a reading from an analogue meter or a bar graph. Present numerical data only when the operator needs to know exact values. This is especially true for rapidly changing readings. When you do need to show actual data values, line them up neatly and consistently.
