Technology is a mainstay in today’s society.
Whether at home, school, or in the workplace, people
use technological systems. Consequently, the average
user is now less likely to understand the systems of
today as compared to the users of 30 years ago.
Therefore, the designers and developers of these
systems must ensure that the systems are designed with
the three “use” words in mind so that the product is
successful. Hence, the system must be useful, usable,
and used [4]. The last of the “use” terms has not been
a major factor until recently, thereby making the
discipline of human-computer interaction increasingly
more important.
