A '''graphical user interface''' (or '''GUI''', often pronounced "goo-ee") is a method of [[human-computer interaction|interacting with a computer]] that uses graphical images and widgets in addition to text.

The graphical user interface was invented at [[Xerox PARC]] and most modern GUIs are derived from it. (Some say GUIs were conceptualized by [[Douglas EnglebartEngelbart|Doug EnglebartEngelbart]] and first created by Xerox.) For this reason, some people call this class of interface a PARC User Interface (PUI). The PUI consists of graphical [[widget]]s such as [[window (computing)|windows]], [[menu (computing)|menu]]s, [[button (computing)|button]]s, [[radio box]]es, and [[icon (computing)|icon]]s, and employs a [[pointing device]] (such as mouse, trackball, or touchscreen) in addition to a keyboard. For this reason, many people refer to PUIs as WIMPs (Windows, Icons, Mouse, Pointer). Widgets are often pre-implemented in the form of [[widget toolkit]]s.

Examples of systems that support PUIs are [[Mac OS]], [[Microsoft Windows]], and the [[X Window System]]. The latter is extended with toolkits such as [[Motif]] ([[CDE]]), [[Qt]] ([[KDE]]) and [[GTK]]+ ([[GNOME]]).
