Interface Design
The creation of a way for a customer, client, or visitor to interact with a product, be it a piece of software, instructional material, technical documentation, etc. The interface may take the form of a computer screen, a hand-held control panel, a set of pushbuttons, etc. Design of the interface is critical to the user's successful, positive experience with the product.
