The user is the ultimate concern in the user interface and the user interface goes a long way in determining the success of a certain product.
When the concept of the interface first began to emerge, it was commonly understood as the hardware and software through which a human and computer could communicate. An Interface can be visualized as the place where contact between two entities occurs. The less alike those two entities are, the more obvious the need for a well-designed interface. The concept of an interface is not a new thing; there are many things in day to day life which are acting as interfaces.
Examples are:


A doorknob is the interface between a person and a door.



The steering wheel, accelerator, clutch and other dash board instruments are the interfaces between a driver and a car.

An interface thus, is the contact surface for a thing.
The shape of the interface reflects the physical qualities of the parties to the interaction (the interactors). A doorknob is hard and firmly mounted because of the nature of the hand that will use it. The doorknob’s physical qualities also reflect the physical aspects of its function. It is designed to be turned so that the latch is released and so that it is easier for the user to pull the door open.
An interface is a contact surface that reflects:




The physical properties of the interactors.
The function to be performed.
The balance of power
