The Interactive System
Description
An interactive system is a computer system which is characterized by a significant amount of
interaction between humans and the computer (Huang & Benyoucef, 2013). Better yet, an
interactive system is any system that will accept input by a user and provide information
feedback to the user (Sauermann & Roach, 2013). Interactive systems can be examined from two
points of view namely the user perspective and the system perspective. To examine a system
from a user perspective we have to consider what a system really is to a user and what the user
expects from the system. From a user perspective a system is:
 A tool they can use to accomplish tasks,
 Something that can accept their input,
 Something that will hopefully display output and
 Often, a source of frustration.
For the sake of this presentation, we have singled out one of the most commonly used
systems in the current digital world. This is e-commerce websites. We will examine e-commerce
websites from a user perspective.
E-commerce websites have mushroomed recently due to the rise of portable digital devices
that can be used to access the internet anytime, anywhere. An e-commerce website is an online
portal that is used in the sale and purchase of goods and services through the internet (Chiou et
al., 2010). The e-commerce is also used in online shopping whereby goods and services are
transferred between two or more parties. It can also be named as electronic business or as e-
business. In the early days this business transactions used to be done through phone calls and

emails while today it is mainly done online. Through the emergence of online shopping business
life has become so easy such that people can shop online without having to travel to far places
and without having to present themselves physically. So many people consider it as the most
convenient way to purchase goods and services by use of smartphones with a connection to the
internet (Sillence et al., 2007).
User Population
We have different e-commerce websites which include the retail selling, business to
business services, auction websites, finance management websites and also the consultancy
websites (Rodgers & Harris, 2003). The target population ranges from teenagers to youths and
even the older generation. It should thus have attractive features to maintain its wide range of
customers. The e-commerce website should at least be neat and user –friendly such that it is easy
for the users to find things such as prices, carts and images of the products.
