Graphical user interface. A graphical user interface (or GUI, often pronounced gooey), is a particular case of user interface for interacting with a computer which employs graphical images and widgets in addition to text to represent the information and actions available to the user.
One main type of user interface is called a graphical user interface (GUI). This includes the interfaces for the modern operating systems many of us are familiar with, particularly Windows, as well as other kinds of software programs that are made to be driven mainly by icons or images rather than text commands.
