Term:GUI [Graphical User Interface]

GUI is an acronym for Graphical User Interface.

A graphical user interface refers specifically to user interfaces (or UIs) which are created graphically, using images, colors and other visual effects, such as those presented by Windows and Windows applications.

This contrasts with a so-called “character mode” user interface, which is constructed solely from characters such as those you might type on a keyboard. The Windows Command Prompt, and the programs that might run within it, are examples of character-mode interfaces.

The graphical user interface (GUI /juːˈ/ jee-you-eye or /ˈɡi/) is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of text-based user interfaces, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard.

The actions in a GUI are usually performed through direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and industrial controls. The term GUI tends not to be applied to other lower-display resolution types of interfaces, such as video games (where head-up display (HUD) is preferred), or not including flat screens, like volumetric displays because the term is restricted to the scope of two-dimensional display screens able to describe generic information, in the tradition of the computer science research at the Xerox Palo Alto Research Center.
