The PC became an object of common use with the introduction of visual environ-
ments made of icons that could be processed with the use of a device called mouse.
This solution turned operations into metaphors of real world actions: select and drag
an icon to move a file, single-clicks to select contents, and double-clicks to open
them.
The main advantage of this new approach to computing was that it didn't need an
expert to use a computer for basic operations. Anyone could use a PC!
The evolution of visual interfaces led to touch interfaces, made possible with the
introduction of screens that could process touch actions directly on the screens of
the devices. This system allows users to use their fingers instead of the mouse of
desktop PCs, thus triggering a revolution in user interfaces and user experience,
as well as offering the possibility of developing devices, such as tablets and smart-
phones, that could handle the same basic operations available on a desktop PC on
a smaller mobile device.
