Interface+Design

User 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 interaction yet also require some unique skills and knowledge. As a result, user interface designers tend to specialize in certain types of projects and have skills centered around their expertise, whether that be [|software design], user research, [|web design], or [|industrial design].
 * User __interface design__** or **user interface engineering** is the design of [|computers], [|appliances], machines, [|mobile communication devices], [|software] applications, and [|websites] with the focus on the [|user's experience] and interaction. Where traditional graphic design seeks to make the object or application physically attractive, the goal of user interface design is to make the user's interaction as intuitive as possible—what is often called [|user-centered design]. Where good graphic/industrial design is bold and eye catching, good user interface design is to facilitate finishing the task at hand over drawing attention to itself. [|Graphic design] may be utilized to apply a theme or style to the interface without compromising its intuitive usability. The intuitiveness of an interface may depend on [|symbology] from an artistic perspective as much as functionality from a technical engineering perspective.
 * Functionality requirements gathering - assembling a list of the functionality required of the system to accomplish the goals of the project and the potential needs of the users.
 * User analysis - analysis of the potential users of the system either through discussion with people who work with the users and/or the potential users themselves. Typical questions involve:
 * What would the user want the system to do?
 * How would the system fit in with the user's normal [|workflow] 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?
