History of the graphical user interface
The graphical user interface, or "GUI", is a computer interface that uses graphic icons and controls in addition to text. The user of the computer utilizes a pointing device, like a mouse, to manipulate these icons and controls. This was a great leap forward from the command line interface used in other operating systems, in which the user types a series of text commands to the computer.
Initial Developments
The first concept of a windowing system begins with the first real-time graphic display systems for computers, namely the SAGE Project and Ivan Sutherland’s Sketchpad.
