What Is A Graphical User Interface? Definition And Faqs


So, instead of dragging and dropping a file to move it, users typed the command name, the name of the file to be moved, and the destination directory. Users had to memorize the commands required to perform these and many other functions. Years ago, before the Apple Macintosh operating system or the Windows operating system, the only way to tell a computer what you wanted was to type text commands into the command-line interface. Believe me, it was more like trying to solve a crossword puzzle with no squares – or hints! Thick user manuals with long lists of parameters and command-line switches (don’t ask!) were your best friend. On the screen – if you even had one – you saw an empty black screen with a flashing block of phosphor.

Another GUI which has grown in popularity, X-Windows, runs on Unix systems. This originated from the Massachusetts Institute of Technology and as such developed in a very open manner. Administration of the development of X has been taken over by the X-Consortium which has been an important factor in getting X made accessible. Beth Mynatt and her colleagues at Georgia Tech have tackled the accessibility of X through their Mercator screen reader.

What is GUI and its advantages?

Advantage #1 – GUIs enable interaction through clarity and control. The primary objective of every GUI is to deliver the kind of clarity that will allow its users to rapidly begin engaging and interacting with it in meaningful ways.


Its goal is to enhance the efficiency and ease of use for the underlying logical design of a stored program, a design discipline named usability. Methods of user-centered design are used to ensure that the visual language introduced in the design is well-tailored to the tasks. The actions in a GUI are usually performed through direct manipulation of the graphical elements.

If you had a keyboard and not just punchcards, you memorized long commands and hoped you didn’t type them in wrong. Smaller app mobile devices such as personal digital assistants and smartphones typically use the WIMP elements with different unifying metaphors, due to constraints in space and available input devices. Applications for which WIMP is not well suited may use newer interaction techniques, collectively termed post-WIMP user interfaces. Designing the visual composition and temporal behavior of a GUI is an important part of software application programming in the area of human–computer interaction.

Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and industrial controls. The earliest GUI was created in the late 1960s by Stanford researcher Douglas Engelbart with his invention of the mouse, which allowed him to directly interact with a computer s graphic display. Xerox s Palo Alto Research Centers further developed Engelbart s concept in the 1970s by creating a windows, icon, menu, and pointer interface. The WIMP GUI uses a pointer to interact with widgets on the graphic display. Right from its first release, Windows 95 will include an off-screen model which software developers will be able to use as the basis of non-visual representations of the screen. To some extent the success of the adaptation has depended on the level of access to the existing visual software. Microsoft’s Windows is the most used GUI and it is with the new release of this software, Windows 95, that possibly the greatest innovation will occur.

Translations Of Graphical User Interface

All actions can be executed from the keyboard, a functionality not available in the Macintosh GUI. The most common SAA-type GUIs are Windows 3.11 for DOS and the Program Manger for OS/2. software construccion To really appreciate GUI design, it helps to know what preceded it. Before GUI was commonly used, computer screens only displayed plain text and were controlled by a keyboard.
