User interface design is important because it affects how one interacts with technology. It is a multi-disciplinary skill that includes graphic design, psychology, and also understanding the workflow process and functionality of the product. A good user interface design makes the product easy to use, which results in a remarkably intuitive behaviour on the part of the user. For example, the iPad predicts the user’s desired action outcomes using only very simple controls, such as swipe, press and hold, double tap and so on. The user screen for any software application should use understandable icons, a layout that respects the hierarchy of vision, sensible fonts and colour combinations. A rule of thumb in designing user interfaces, as in all design in general: Keep It Simple and Stupid (KISS).
