What Is Graphical User Interface


It allows users to use input devices such as a mouse to manipulate icons or menu options on the screen to select commands, invoke files, start programs or perform other daily tasks. GUI refers to graphical user interface which allows users to interact with electronic devices through graphical icons. Graphical user interfaces are visually more acceptable to users than command-line interfaces used by computers in the early days.

This Type Of Design Makes Using Your Computer Easier

  • Applications may also provide both interfaces, and when they do the GUI is usually a WIMP wrapper around the command-line version.
  • 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.
  • This is especially common with applications designed for Unix-like operating systems.
  • 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 Wrappers

With height and width, they offer a third dimension of layering or stacking screen elements over one another. This may be represented visually on screen through an illusionary transparent effect, which offers the advantage that information in background windows may still be read, if not interacted with. Or the environment may simply hide the background information, possibly making the distinction apparent by drawing a drop shadow effect over it. These visual representations consist of elements like icons, menus, tabs, pointers and windows, which allow users to easily access and manipulate available functions. To select functions, users can either use a keyboard or pointing device, such as a mouse or a touchpad. In addition, devices with touchscreens also allow for user input by touching the screen.

graphical user interface windows

Windows are the basic units that the application sets in the graphical user interface for using data. A window is an area on the screen where information is displayed. In the window, the user can manipulate the application in the window to manage, generate and edit the data. Usually, there are menus and icons around the window, and the data is placed in the center. A GUI may be designed for the requirements of a vertical market as application-specific graphical user interfaces. 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. 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. I concentrated on the use of sounds (speech and non-speech) and on making the mouse usable in a non-visual interaction.

Why GUI is used?

The graphical user interface (GUI; sometimes pronounced “gooey”) is used by most commercially popular computer operating systems and software programs today. It’s the kind of interface that allows users to manipulate elements on the screen using a mouse, a stylus, or even a finger.

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 software mantenimiento commands in it. For typical computer displays, three-dimensional is a misnomer—their displays are two-dimensional, for example, Metisse characterized itself as a «2.5-dimensional» UI. Semantically, however, most graphical user interfaces use three dimensions.

What is the difference between GUI and UI?

GUI is «graphical user interface» and UI is just «user interface.» GUI is a subset of UI. UI can include non-graphical interfaces such as screen readers or command line interfaces which aren’t considered GUI.
