A graphical user interface (GUI, pronounced /ˈɡuː.i/[1]) is a type of user interface The user interface (also known as human computer interface or man-machine interface ) is the aggregate of means by which people—the users—interact with the system—a particular machine, device, computer program or other complex tool. The user interface provides means of: which allows people to interact with electronic devices Human–computer interaction is the study of interaction between people (users) and computers. It is often regarded as the intersection of computer science, behavioral sciences, design and several other fields of study. Interaction between users and computers occurs at the user interface (or simply interface), which includes both software and such as computers; hand-held devices such as MP3 Players, Portable Media Players or Gaming devices; household appliances and office equipment with images rather than text commands. A GUI offers graphical icons, and visual indicators, as opposed to text-based Usually used in reference to a computer application, especially a computer game, a text-based application is one whose primary input and output are based on text rather than graphics. This does not mean that text-based applications do not have graphics, just that the graphics are secondary to the text interfaces, typed command labels or text navigation to fully represent the information and actions available to a user. The actions are usually performed through direct manipulation Direct manipulation is a human-computer interaction style which involves continuous representation of objects of interest, and rapid, reversible, incremental actions and feedback. The intention is to allow a user to directly manipulate objects presented to them, using actions that correspond at least loosely to the physical world. Having real- of the graphical elements.[2]
The term GUI is historically restricted to the scope of two-dimensional display screens with display resolutions capable of describing generic information, in the tradition of the computer science Computer science is the study of the theoretical foundations of information and computation, and of practical techniques for their implementation and application in computer systems. It is frequently described as the systematic study of algorithmic processes that describe and transform information. According to Peter J. Denning, the fundamental research at Palo Alto Research Center PARC , formerly Xerox PARC, is a research and development company in Palo Alto, California with a distinguished reputation for its contributions to information technology (PARC). The term GUI earlier might have been applicable to other high-resolution types of interfaces The user interface (also known as human computer interface or man-machine interface ) is the aggregate of means by which people—the users—interact with the system—a particular machine, device, computer program or other complex tool. The user interface provides means of: that are non-generic, such as videogames A video game is an electronic game that involves interaction with a user interface to generate visual feedback on a video device. The word video in video game traditionally referred to a raster display device. However, with the popular use of the term "video game", it now implies any type of display device. The electronic systems used to, or not restricted to flat screens, like volumetric displays.[3]
