086 Mapping
A correspondence in layout and movement between controls and the things they control.
• Good mapping occurs when there is a strong correspondence in layout and movement between controls and the things they control. Good mapping makes things intuitive to use.
• Bad mapping occurs when there is a weak correspondence in layout and movement between controls and the things they control. Bad mapping makes things counterintuitive to use.
• For example, pushing a switch up to move a car window up is good mapping. Pushing a switch up to move a car window down is bad mapping.
• Ensure good mapping in your designs to minimize errors and make things easy to use.
