HUMAN FACTORS AND SYSTEM DESIGN2
Part One: Interactive System and its Users
The interactive system that is being evaluated in this report is the system of iTunes which
is digital music application of Apple (Nascimento et al. 2017). The evaluation was done with the
help of heuristic evaluation including different usability method. This heuristics method of
evaluation includes many evaluators stating predefined usability principles for a particular
application as well as principles of website to complete this task.
The interactive iTunes is music application that can be used with Windows as well as the
Mac users. This interactive system helps to manage digital music library in the computer system.
With this system, the users can listen songs as per their choice from their CDs and they can store
all those songs as MP3 music on the music library. The users can also create their mixes so that
they can create playlist which are customizable. This includes smart playlists and the users using
the iTunes can also record all those songs to CDs. At the time is listening to the music, the users
using the iTunes can also watch visuals on the window of iTunes or can watch video as full
screen. The system of iTunes are also compatible with iPod, MP3 music player of Apple. The
users can transfer songs between the interfaces of the system. Songs can also be transferred to
computer system or in mobile device system (Schnall et al. 2016). This system of iTunes has a
unique feature which enables the users to search music. The users can search for music suing the
iTunes Music Store and can also buy those music at the rate 99 cents. The best thing that system
provides is that the users does not have to subscribe for taking the advantage of the features. The
application of iTunes is free of cost can be downloaded from the official website of Apple.
This interactive system’s target users are those people who uses MacOS X on their
computer system or uses Windows 2000 or uses Windows XP for their listening to music. There

are another target people of iTunes that is people who listens to the music, organizes the music,
as well as downloads music to be a part of the target population (Kölling and McKay 2016). No
specific demographic targets are not carried out while using conducting this evaluation testing.
Part Two: Use cases
The application system is capable of storing thousands of music and enables the people to
search for the music when they want to. The users can easily manage their music digital library
using this system and can easily rip songs from any CDs so that they can store the MP3 music on
their systems and listen to them whenever necessary.

The users can also mixes the songs and create their own customizable playlists and can
even burn those customized music to a CD or can transfer them to their computer system or on
