The Xerox PARC user interface consisted of graphical elements such as windows, menus, radio buttons, and check boxes. The concept of icons was later introduced by David Canfield Smith, who had written a thesis on the subject under the guidance of Kay.
- The graphical user interface (GUI; sometimes pronounced “gooey”) is used by most commercially popular computer operating systems and software programs today.
- GUI is the acronym for graphical user interface, which is the interface through which users interact with electronic devices, such as computers, laptops, smartphones and tablets.
- A graphical user interface offers visual representations of the available commands and functions of an operating system or software program.
- Designing programs this way also allows users to run the program in a shell script.
- This kind of interface allows word processing or web design programs, for example, to offer WYSIWYG options.
- It’s the kind of interface that allows users to manipulate elements on the screen using a mouse, a stylus, or even a finger.
The film Minority Report has scenes of police officers using specialized 3D data systems. In prose fiction, three-dimensional user interfaces have been portrayed as immersible environments like William Gibson’s Cyberspace or Neal Stephenson’s Metaverse. Many futuristic imaginings of user interfaces rely heavily on object-oriented user interface style and especially object-oriented graphical user interface style. Since the commands available in command line interfaces can be many, complex operations can be performed using a short sequence of words and symbols. This allows greater efficiency and productivity once many commands are learned, but reaching this level takes some time because the command words may not be easily discoverable or mnemonic. Also, using the command line can become slow and error-prone when users must enter long commands comprising many parameters or several different filenames at once. However, windows, icons, menus, pointer interfaces present users with many widgets that represent and can trigger some of the system’s available commands.
Apple introduced the Macintosh as a computer «for rest of us.» The GUI was a major part of the overall goal of the Macintosh. All graphical applications oracionesasanmiguelarcangel.com copied the Macintosh in its design and usage. The Macintosh introduced the first menu, icons, and point-and-click, mouse driven processing.
How does a user interface work?
A user interface (UI) refers to the part of an operating system, program, or device that allows a user to enter and receive information. A text-based user interface (see the image to the left) displays text, and its commands are usually typed on a command line using a keyboard.

The PARC user interface employs a pointing device along with a keyboard. These aspects can be emphasized by using the alternative term and acronym for windows, icons, menus, pointing device . This effort culminated in the 1973 Xerox Alto, the first computer with a GUI, though the system never reached commercial production. The WIMP style of interaction uses a virtual input device to represent the position of a pointing device’s interface, most often a mouse, and presents information organized in windows and represented with icons. Available commands are compiled together in menus, and actions are performed making gestures with the pointing device. A window manager facilitates the interactions between windows, applications, and the windowing system. The windowing system handles hardware devices such as pointing devices, graphics hardware, and positioning of the pointer.
For instance, when you click on an icon and open up an application or a file, it will open up in its own window. Even users who are not experienced with GUI interfaces can easily manipulate windows. For example, one can show or hide a window by clicking on an icon or a function button and can move a window by clicking on it and dragging it to a new position. Every technological device that requires user interaction employs a user interface. Common devices the public use on a daily basis include smartphones, computers and tablets, which all feature graphical user interfaces. Although it may seem that we have always had the ease of use of GUIs, the public only gained access to this technology in the 1980s.
What is a user interface example?
A common example of a hardware device with a user interface is a remote control. This set of buttons and the way they are laid out on the controller makes up the user interface. Other devices, such as digital cameras, audio mixing consoles, and stereo systems also have a user interface.
The graphical user interface is presented on the computer screen. It is the result of processed user input and usually the main interface for human-machine interaction. The touch user interfaces popular on small mobile devices are an overlay of the visual output to the visual input.
How Does A Graphical User Interface Work?
GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces , which require commands to be typed on a computer keyboard. The common method of interacting with a computer that allows any image to be displayed on screen. Except for entering text on the keyboard, the primary way the computer is operated is with a mouse or touchpad pointing device. The mouse/touchpad is used to select icons and menu options as well as move and resize windows that frame the application and elements within it.
The visible graphical interface features of an application are sometimes referred to as chrome or GUI . Typically, users interact with information by manipulating visual widgets that allow for interactions appropriate to the kind of data they hold. The widgets of a well-designed interface are selected to support the actions necessary to achieve the goals of users. A model–view–controller allows flexible structures in which the interface is independent of and indirectly linked to application functions, so the GUI can be customized easily. This allows users to select or design a different skin at will, and eases the designer’s work to change the interface as user needs evolve. Good user interface design relates to users more, and to system architecture less. Large widgets, such as windows, usually provide a frame or container for the main presentation content such as a web page, email message, or drawing.
With these menus and icons, the Macintosh was the first computer system that limited the users to contextual correct answers. For example, once the user made a selection via a menu, the menu limited the user’s subsequent actions. The Macintosh’s GUI has all three major components of a GUI, which are the windowing system, an imaging model, and an API. A window is a rectangular area of the GUI interface that displays information independently from the rest of the screen.
