WIMP (computing)

In human–computer interaction, WIMP stands for "windows, icons, menus, pointer", denoting a style of interaction using these elements of the user interface. Other expansions are sometimes used, such as substituting "mouse" and "mice" for menus, or "pull-down menu" and "pointing" for pointer. Although the acronym has fallen into disuse, it has often been likened to the term graphical user interface (GUI). Any interface that uses graphics can be called a GUI, and WIMP systems derive from such systems. However, while all WIMP systems use graphics as a key element (the icon and pointer elements), and therefore are GUIs, the reverse is not true. Some GUIs are not based in windows, icons, menus, and pointers. For example, most mobile phones represent actions as icons and menus, but often do not rely on a conventional pointer or containerized windows to host program interactions. WIMP interaction was developed at Xerox PARC (see Xerox Alto, developed in 1973) and popularized with Apple's introduction of the Macintosh in 1984, which added the concepts of the "menu bar" and extended window management. The WIMP interface has the following components: A window runs a self-contained program, isolated from other programs that (if in a multi-program operating system) run at the same time in other windows. These individual program containers enable users to move fluidly between different windows. The window manager software is typically designed such that it is clear which window is currently active. Design principles of spacing, grouping, and simplicity help the user maintain focus when working between more than one window. An icon acts as a shortcut to an action the computer performs (e.g., execute a program or task). Text labels can be used alongside icons to help identification for small icon sets. A menu is a text or icon-based selection system that selects and...
