GUI
GUI
follows to interact with a particular computer. A few years ago, the way
in which users had access to a computer system was quite complex.
They had to memorize and type a lot of commands just to see the
content of a disk or to copy files. In fact, only experts used computers,
so there was no need for a user-friendly interface. Now, however,
computers are used by all kinds of people, and as a result, there is a
growing emphasis on the user interface.
A good user interface is important because when you buy a program
you want to use it easily. Moreover, a graphical user interface saves a
lot of time. You don’t need to memorize commands in order to
execute an application; you only have to point and click so that its
content appears on the screen. For example, Macintosh computers –
with a user interface based on graphics and special tools – were
designed with a single clear aim: to facilitate interaction with the
computer. Their interface is called WIMP: Window, Icon, Menu (or
Mouse), and Pointer, and software products for the Macintosh have
been designed to take full advantage of its features using this
interface.
Today, the most creative GUIs are the Macintosh, Microsoft Windows,
and IBM OS/2 Warp. These three GUIs include similar features: a
desktop with icons, windows and folders, a printer selector, a file
finder, a control panel, and various desk accessories. For instance,
double-clicking a folder opens a window which contains programs or
documents.
These interfaces have been so successful because they are easy to use.
It is well-known that computers running under an attractive interface
help users to be more creative and produce high-quality results.
