Jump to bitcoin cli commands dos Jump to search “GUI” redirects here. The actions in a GUI are usually performed through direct manipulation of the graphical elements.

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. 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. Smaller ones usually act as a user-input tool.

A GUI may be designed for the requirements of a vertical market as application-specific graphical user interfaces. By the 1980s, cell phones and handheld game systems also employed application specific touchscreen GUIs. Newer automobiles use GUIs in their navigation systems and multimedia centers, or navigation multimedia center combinations. A GUI uses a combination of technologies and devices to provide a platform that users can interact with, for the tasks of gathering and producing information. A series of elements conforming a visual language have evolved to represent information stored in computers.

This makes it easier for people with few computer skills to work with and use computer software. The WIMP style of interaction uses a virtual input device to represent the position of a pointing device, 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. In personal computers, all these elements are modeled through a desktop metaphor to produce a simulation called a desktop environment in which the display represents a desktop, on which documents and folders of documents can be placed.

WIMP elements with different unifying metaphors, due to constraints in space and available input devices. Android use the class of GUIs named post-WIMP. These support styles of interaction using more than one finger in contact with a display, which allows actions such as pinching and rotating, which are unsupported by one pointer and mouse. There are also actions performed by programs that affect the GUI. For example, there are components like inotify or D-Bus to facilitate communication between computer programs.

Ivan Sutherland developed Sketchpad in 1963, widely held as the first graphical computer-aided design program. It used a light pen to create and manipulate objects in engineering drawings in realtime with coordinated graphics. The Xerox Star 8010 workstation introduced the first commercial GUI. The Xerox PARC user interface consisted of graphical elements such as windows, menus, radio buttons, and check boxes. The first commercially available computer with a GUI was the 1979 PERQ workstation, manufactured by Three Rivers Computer Corporation. GUIs were a hot topic in the early 1980s. Individual applications for many platforms presented their own GUI variants.
