The first commercially available GUI, called «PARC,» was developed by Xerox. It was used by the Xerox 8010 Information System, which was released in 1981. After Steve Jobs saw the interface during a tour at Xerox, he had his team at Apple develop an operating system with a similar design. Apple’s GUI-based OS was included with the Macintosh, which was released in 1984. Microsoft released their first GUI-based OS, Windows 1.0, in 1985.

The marketplace does attempt to access these attributes, however , but even after over 10 years of GUI development, there are still questions concerning what is a good GUI design. The GUI interface has also been instrumental in making the World Wide Web easily accessible to individuals through the use of GUI-based «browser» programs. Netscape Navigator, Internet Explorer, and similar programs enable a user to access and search the Web using the familiar GUI format. Information in an application can be directly read or influences using the graphical control elements. Normally, widgets are used to display lists of similar items, navigate the system using links, tabs etc. and manipulating data using check boxes, radio boxes etc. Another type of menu is the context menu that appears only when the user performs a specific action.

  • GUI representations are manipulated by a pointing device such as a mouse, trackball, stylus, or a finger on a touchscreen.

As you might imagine, GUI systems have made computers far more user-friendly than CLI systems. The zooming user interface is a related technology that promises to deliver the representation benefits of 3D environments without their usability drawbacks of orientation problems and hidden objects. It is a logical advance on the GUI, blending some three-dimensional movement with software mantenimiento two-dimensional or 2.5D vector objects. In 2006, Hillcrest Labs introduced the first zooming user interface for television. WIMPs extensively use modes, as the meaning of all keys and clicks on specific positions on the screen are redefined all the time. Command-line interfaces use modes only in limited forms, such as for current directory and environment variables.

It will respond by creating a new dialog box asking you how you want to have the page print out. A GUI allows the user of a computer to communicate with the computer by moving a pointer around on a screen and clicking a button. Although Apple was the first to mass-produce a successful GUI, they were not the inventors of the idea, nor were they the first to market it. The honour for implementing the first working GUI goes to Doug Englebart – at the time an employee of Stanford Research Institute. The Xerox Palo Alto Research Center was convinced that Englebart’s model would work on computers available for individual work stations, and they created two working models, the Alto and the Star. The Star was made available to the public, mouse and all, in 1981.
