In the last 20 years, the introduction of
the graphical user interface (GUI) has
revolutionised the ways in which
users interact with computers, known
as human computer interaction (HCI).
After completing this unit, you should
be able to achieve these outcomes:
Know about the impact of HCI on society,
economy and culture.
Understand the fundamental principles of interface
Be able to design and produce simple interactive
computer input and output based on HCI
Be able to compare and contrast, using HCI
principles, the effectiveness of different designs
of input and output.
Probably the most recognised graphical
user interface (GUI) is that used on PCs
Microsoft Windows was based on the
earlier Macintosh model.

Historically, early HCI designs were
restricted by the hardware. Users were
required to type in lengthy code into the
computer just to log in.

In 1984 the Macintosh computer appeared
GUIs in the form of a computerised desktop,
icons that were images, files, rubbish bin
with the addition of a mouse, enabling the
user to locate documents and put them in
the bin and click on them to open them .
This desktop design has truly influenced
how users interact with computers today
Investigate the tension between Macintosh
and Microsoft regarding the development
of their GUIs.
Why the tension arose, when and what
happened as a result.
