Graphical User Interface


The command interface of the DOS operating system is an example of the typical user-computer interface before GUIs arrived. An intermediate step in user interfaces between the command line interface and the GUI was the non-graphical menu-based interface, which let you interact by using a mouse rather than by having to type in keyboard commands. There are a variety of university-level computer-human interaction programs. Although a few offer breath and diversity, many students graduate from universities that offer only one or two CHI courses.

What does GUI mean in text?

Summary of Key Points. «Graphical User Interface» is the most common definition for GUI on Snapchat, WhatsApp, Facebook, Twitter, and Instagram. GUI. Definition: Graphical User Interface.

Many modern graphical user interfaces feature touchscreen and voice-command interaction capabilities. A graphical user interface refers to the way users interact with computers, cell phones and other modern devices. A graphical user interface is characterized by icons, windows, menus and other objects on the screen that make applications easy to navigate with just the click of a mouse, the touch of a finger, or a keyboard shortcut. The proliferation of graphical user interfaces has made technology accessible even to people with very limited computer skills. By selecting one of these graphical elements, through either use of a mouse or a selection from a menu, the user can initiate different activities, such as starting a program or printing a document.

What Is A Graphical User Interface (gui)?

It explains in computing terminology what GUI means and is one of many software terms in the TechTerms dictionary. Three-dimensional graphics are currently mostly used in computer games, art, and computer-aided design . A three-dimensional computing environment can also be useful in other uses, like molecular graphics, aircraft design and Phase Equilibrium Calculations/Design of unit operations and chemical processes. Windows 95, accompanied by an extensive marketing campaign, was a major success in the marketplace at launch and shortly became the most popular desktop operating system. There are also actions performed by programs that affect the GUI.

3 Gui Programming Options¶

History Of Gui

Some common GUIs are the ones associated with Microsoft Windows, Mac OSX, Chrome OS, GNOME, KDE, and Android. GUIs sort of bring computers and users out of the stone age and into the future. A graphical user interface uses graphics, along with a keyboard and a mouse, to provide an easy-to-use interface to a program. A GUI provides windows, pull-down menus, buttons, scrollbars, iconic images, wizards, other icons, and the mouse to enable users to interact with the operating system or application. 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.

Applications may also provide both interfaces, and when they do the GUI is usually a WIMP wrapper around the command-line version. This is especially common with applications designed for Unix-like operating systems. The latter used to be implemented first because it allowed the developers to focus exclusively on their product’s functionality without bothering about interface details such as designing icons and placing buttons. Designing programs this way also allows users to run the program in a shell script. A graphical user interface is a way to communicate what you want to a computer application or operating system without typing the instructions in. We can trace the history of the user interface from command-line interfaces to graphical ones . The main pieces of a GUI are a pointer, icons, windows, menus, scroll bars, and an intuitive input device.

Why is GUI interface so popular?

Most people will be attracted to GUIs because they are cognitively easier to use. Command line interfaces force you to memorize and recall commands in order to do anything. Even to conjure up a help menu or a list of commands, you must know what to type.

Prior to the introduction of GUI environments, most interactive user interface programs were text oriented and required the user to learn a set of often complex commands that are unique to a given program. The first GUI was developed in the 1970s by Xerox Corporation, although GUIs did not become popular until the 1980s with the emergence of the Apple Macintosh computer. Today, the most familiar GUI interfaces are Apple Computer’s Macintosh and Microsoft Corporation’s Windows operating systems. Graphical user interface wrappers find a way around the command-line software transportes interface versions of Linux and Unix-like software applications and their text-based user interfaces or typed command labels. While command-line or text-based applications allow users to run a program non-interactively, GUI wrappers atop them avoid the steep learning curve of the command-line, which requires commands to be typed on the keyboard. By starting a GUI wrapper, users can intuitively interact with, start, stop, and change its working parameters, through graphical icons and visual indicators of a desktop environment, for example.

GUI is an interface that allows users to interact with different electronic devices using icons and other visual indicators. The graphical user interfaces were created because command line interfaces were quite complicated and it was difficult to learn all the commands in it. As you read this, you are looking at the GUI or graphical user interface of your particular Web browser.

This makes the user open a video player like VLC just by the click of a button. By 1990, GUIs began to look more like those used on modern devices. Apple founder Steve Jobs saw it during a tour of Xerox and released a GUI-based operating system for the Macintosh in 1984. For example, there are still word processing shortcuts in modern programs from the infamous WordStar for CP/M, which had the strangest keyboard combinations you will ever see.

  • While these types of input devices are sufficient for desktop computers, they do not work as well for mobile devices, such as smartphones and tablets.
  • For several decades, GUIs were controlled exclusively by a mouse and a keyboard.
  • This means that small mistakes, like spelling errors or incorrect spacing, will prevent a function from being executed.
  • Therefore, mobile operating systems are designed to use a touchscreen interface.
  • Many mobile devices can now be controlled by spoken commands as well.
  • Menus are graphical representations of available software commands.

For example, there are components like inotify or D-Bus to facilitate communication between computer programs.
