It also discusses the design patterns and various software design notations used to represent a software design. Basic of Software Design Software design is a phase in software engineering, in which a blueprint is developed to serve as a base for constructing the software system. The graphical user interface is presented (displayed) on the computer screen. It is the result of processed user input and usually the primary interface for human-machine interaction. The popular on small mobile devices are an overlay of the visual output to the visual input. User interface design ( UI) or user interface engineering is the of for and, such as,,, and other, with the focus on maximizing and the. The goal of user interface design is to make the user's interaction as simple and efficient as possible, in terms of accomplishing user goals (). Good user interface design facilitates finishing the task at hand without drawing unnecessary attention to itself. And are utilized to support its, influencing how the user performs certain interactions and improving the aesthetic appeal of the design; design aesthetics may enhance or detract from the ability of users to use the functions of the interface. The design process must balance technical functionality and visual elements (e.g., ) to create a system that is not only operational but also usable and adaptable to changing user needs. Interface design is involved in a wide range of projects from computer systems, to cars, to commercial planes; all of these projects involve much of the same basic human interactions yet also require some unique skills and knowledge. As a result, designers tend to specialize in certain types of projects and have skills centered on their expertise, whether that be, user research,,.

Basic Graphic Design PrinciplesThere are several phases and processes in the user interface design, some of which are more demanded upon than others, depending on the project. (Note: for the remainder of this section, the word system is used to denote any project whether it is a,, or.) • Functionality requirements gathering – assembling a list of the functionality required by the system to accomplish the goals of the project and the potential needs of the users. • and – a form of, it's the analysis of the potential users of the system by studying how they perform the tasks that the design must support, and conducting interviews to elucidate their goals. Typical questions involve: • What would the user want the system to do? • How would the system fit in with the user's normal or daily activities? • How technically savvy is the user and what similar systems does the user already use? • What interface look & feel styles appeal to the user? • – development of the process and/or information flow of the system (i.e. For phone tree systems, this would be an option tree flowchart and for web sites this would be a site flow that shows the hierarchy of the pages). • Prototyping – development of, either in the form of or simple interactive screens. These prototypes are stripped of all look & feel elements and most content in order to concentrate on the interface. • – letting an evaluator inspect a user interface.
