What Is Contact Center Gui Graphical User Interface


The figure at right shows Java Swing’s text field, called JTextField. The view is an object that draws the text on the screen (usually with a rectangle around it to indicate that it’s an editable text field). The controller is an object that receives keystrokes typed by the user and inserts them into the mutable string.

At that time, no one thought normal people could use a computer. But, now everyone owns a computer and has a basic knowledge of how to use it. Instead, it provided more for the user to actually start using the computer. The Information Technology boomed with several jobs offers being presented to the people for designing and developing GUI. Future languages have adapted itself and are being used to develop the GUI. It will always have the eternal scope in the job market and GUI will continue to improve and update itself into a more usable and simpler user interface and change the world as it has already done in the past. GUI may be simple for a consumer but not as simple for the programmers who have to design and implement each and every function and also apply abstraction so that the users will feel the advantages of GUI.

History Of Gui

If for example, a user starts using a computer with no Interface, then he/she has to provide commands to the machine to execute each task. In a way, the user must have some kind of programming knowledge. GUI is a Graphical Interface which is a visual representation of communication presented to the user for easy interaction with the machine. Some environments use the methods of 3D graphics to project virtual three-dimensional user interface objects onto the screen. As the processing power of computer graphics hardware increases, this becomes less of an obstacle to a smooth user experience.

A view usually occupies some chunk of the screen, usually a rectangular area. Basically, the view queries the model for data and draws the data on the screen. It listens for changes from the model so that it can update the screen to reflect those changes. We’ve seen how GUI programs are structured around a view tree, and how input events are handled by attaching listeners to views. This is the start of a separation of concerns – output handled by views, and input handled by listeners. The last part – listeners return to the event loop as fast as possible – is very important, because it preserves the responsiveness of the user interface. Views can have input handlers, and the view tree controls how mouse and keyboard input is processed.

What is GUI and its features?

Graphical user interface is sometimes shortened to GUI. The user chooses an option usually by pointing a mouse at an icon representing that option. Features of GUIs include: They are much easier to use for beginners. They enable you to easily exchange information between software using cut and paste or ‘drag and drop’.

Today, personal computers are relatively easy to use because they are based on a visual language, representing system operations with icons and employing a visual metaphor – the desktop. The GUI has become standard on the vast majority of desktop computers , to the point where the desktop metaphor is transparent. Relatively inexpensive and fantastically easy to use, the «Mac» was a smashing success, despite the limited computing power and memory housed in the chassis. Programs like MacPaint, which contained the seminal elements of Photoshop, the king of modern graphics editing programs, turned an entire generation of artists on to the possibilities of digital art. There was a shortage of software, but companies were eager to develop for the Mac, seeing its potential for widespread infiltration into the non-techie market.

Other examples of windows are child windows, which open as a result of user activity in a parent window, a pop-up window and a message window, or dialog box, that provides information or asks input from a user. Users select one or a combination of the above elements by pressing keys on a keyboard, clicking with a mouse, or tapping on the screen. These actions make it simple to start applications, open files, navigate websites, and perform other tasks.

  • The WIMP style of interaction uses a virtual input device to represent the position of a pointing device’s interface, most often a mouse, and presents information organized in windows and represented with icons.
  • Nevertheless, as a medium of communication with machines, they would only build upon the revolutionary changes introduced by the graphical user interface.
  • Although the GUI continued to evolve through the 1990s, particularly as features of Internet software began to appear in more general applications, software designers actively researched its replacement.
  • Most applications like Windows, OSX, iOS, Android, Microsoft Office and Adobe Photoshop are examples of GUIs.
  • By making use of powerful advances in speech recognition and natural language processing, these new interfaces might be more intuitive and effective than ever.

Moreover, it can be moved to any area by dragging it around.In a multitasking environment, multiple windows can be open at the same time, all of them performing different tasks. The GUI familiar to most of us today in either the Mac or the Windows operating systems and their applications originated at the Xerox Palo Alto Research Laboratory in the late 1970s. Later, Microsoft used many of the same ideas in their first version of the Windows operating system for IBM-compatible PCs. You can also adjust the size of a window and can easily navigate inside the window through the use of scrollbars and other functions.

Informational components inform users of the status of a task. Examples include notifications of incoming messages, progress bars, tooltips, and pop-up windows. Windows can be moved, resized, and placed in front of each other.

One of the biggest software developers for the Macintosh was a company called Microsoft. This happens because input handling and screen repainting is all handled from a single thread. That thread (called the event-dispatch thread) has a loop that reads an input event from the queue and dispatches it to listeners on the view tree. When there are no input events left to process, it repaints the screen.

In 1984, Apple released a television commercial which introduced the Apple Macintosh during the telecast of Super Bowl XVIII by CBS, with allusions to George Orwell’s noted novel Nineteen Eighty-Four. As of 2011, some touchscreen-based operating systems such as Apple’s iOS and 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. Window managers and other software combine to simulate the desktop environment with varying degrees of realism.
