Considering the fact that we live in what is often described as the cyber age, it is only natural that we will have to come across various manifestations of the web technology in the different spheres of our daily lives. The very concept of the user interface is one such visible symptom of the aforementioned phenomenon. User interface design or user interface engineering as it is also referred to as, can be defined as the process of designing the computers, various appliances, machines, especially the mobile communication devices and accessories, software applications, along with websites where the primary focus is on the experience and interaction of the individual user.

The prime objective of a user interface design can be realized as an effort not only to simplify the user’s interaction procedure but also as competent as possible, that is mainly in terms of achieving the goals of the user which is often described as a user-centered design. One of the most accepted and common feature of an ideal or high quality user interface design should be the fact that it will facilitate, with no needless attention seeking to itself, the finishing of the assignment just around the corner. In fact, graphic design can even be used to validate a particular theme or a particular style to an interface while at the same time the usability factor will remain as it is without getting even slightly compromised.

One of the very basic objects of the entire process of the design is to ensure the equilibrium between the technical purpose as well as the visual elements that is the mental model, so as to build a particular system which will not only just be equipped but also utilizable and adjustable to the changing requirements and needs of the user. There are simply a huge and equally diversified range of projects from computer accessories, systems or peripherals, to automobiles, to even commercial airplanes that either involve or directly apply the fundamentals of the concept of Interface design. Although most of these assignments engage a good deal of the very basic human communication, there are certain cases which also demand a certain extent of exclusive skills and awareness. Thus in consequence, the designers mostly have a propensity to concentrate in certain kinds of assignments and encompass skills which are revolving around their technical know how, which can either be designing software, user research, web designing or even industrial design. However, it must be noted that there are several distinct and diverse steps, phases and processes that in its entirety constitute the user interface design. Among all these above mentioned phases, some of them are more stipulated than the rest, dependant up on the particular assignment.
