Graphical user interface
The graphical user interface (GUI) is a form of user interface that allows users to interact with electronic devices through graphical icons and an 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 heads-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.
