What is a graphical user interface?

For many years, programming languages ​​have been managed exclusively by the command line. This has reduced users with people who had a language skill to give out cryptic data to manipulate data. The graphical user interface (GUI) is like dressing windows for programming language. It creates a graphical representation of a desktop style environment with icons and offers representing objects and commands. The user can show and click on handling data and programs without knowing the basic language or single command.

Anyone who was old at the age of 80 to be aware of the computer revolution, undoubtedly remembers the success of Apple® Macintosh® with its revolutionary graphical interface and mouse. This was the first commercially successful and affordable computer that anyone could use, programming knowledge is not required. Microsoft® quickly followed by the Windows® operating system and no one looked at. The graphical interface was not only efficient and easy, but thatKé fun.

While Apple and Microsoft brought GUI to our homes, they were not responsible for inventing the first graphical user interface. Between 1965-1968, the Doug Engelbart became the Stanford Research Institute at the time, connecting with some colleagues to create a hypertext environment in the style of a window extended by an invention of a small three Gizmo button that would allow the user to point and click on objects in the window. Gizmo, with his buttons, nose and electric "tail", resembled a mouse, so the device got its name. Engelbart's inspiration for GUI came partly from the ideas designed thirty years ago by the praised American engineer Vannevar Bush in his published post on the 1945 "Mex" system.

Xerox® Corporation has developed two computers with a graphical user interface and mouse modeled after RT engines. Alt and star; He released in RocE 1981 to the public. The computer was expensive and hardware insufficient due to the needs of the operating system. Although it sold only reported 25,000 units, it is assumed that it is at least partially responsible for the inspiration of Steve Jobs (Apple Founder) and Bill Gates (Microsoft founder) to push their development teams to create Macintosh and Windows operating systems.

Because the graphical user interface is the first thing the user sees when the program opens, can design a visually attractive interface a long way to create the attraction of the program. However, the most important factor is whether GUI is intuitive. Anyone who has some experience in using software should be able to find basic features in an unknown program without advising a manual, search for offers, tools and options if expected. Advanced or proprietary functions should be integrated in a way that the user has the user is not a job, how to remember, how to get and use them. FSo far, Lashy Gui will only lead the program. If the graphical user interface is not intuitive and efficiently designed, the software is unlikely to become very popular.
