A '''graphical user interface''' is a [[human-computer interaction]] method that uses graphical images in addition to text.

▲It typically uses [[widget]]s such as menus, buttons, radio boxes, and icons,
and usually employs a pointing device (such as mouse, trackball, or touchscreen)
in addition to a keyboard.
It is commonly referred to by its acronym '''GUI''', pronounced like "gooey", and most GUI environments can also be called WIMP (Windows, Icons, Mouse, Pointer).▼

Examples of GUIs include [[Mac OS]], [[Microsoft Windows]], and the
[[X Window System]] (including [[KDE]] and [[GNOME]]).
Similar to GUIs are text user interfaces (TUIs) that display the
same types of widgets in a character-cell mode rather than in a pixel mode.
Examples include the interfaces of many [[ncurses]] and [[MS-DOS]] applications.
The graphical user interface is generally contrasted with the [[command line interface]].
Because GUIs and TUIs tend to show most or all relevant categories of commands on the display, users often learn them faster than CLIs,
but users with vision or motion [[disability]] often have trouble navigating in a GUI,
and most commercial GUIs use at least an order of magnitude more computer power than a CLI, making a GUI unwieldy on older hardware.
