Navigation controls

In human-computer interaction, navigation controls are an arrangement of (word/icon) forms within the user interface of a specific system. This system can be a computer-based application, an application on a wireless device (like a cell-phone), a GPS appliance (in your car or your backpack), or any manner of system that requires human-computer interaction with a stored program. The quality of the user interface is critically dependent on navigation controls that make sense and allow the operator to smoothly negotiate the application in question.
