1.0. Introduction
MusikCube is a music application. If you’re not already committed to downloaded music from
the iTunes Music Store, then MusikCube is the best choice available for a music organizer and
player. It organizes your mp3s, makes it really easy and really fast to find them, and allows you
to make some incredibly clever smart playlists.musikCube was a clean, light weight music
library for Windows. It was actively developed between 2003 and 2006. Now it's an abandoned
open source project. In order to design a user interaction for an application MusikCube was
chosen under copy write laws. While using this application many problems were found and those
problems were established by applying Human Computer Interaction concepts.

Table 2 : Lab works 2
c) List set of usability goals that you think will be most relevant. Explain why.
• Effective to use: - use pictures for each album (relevant) therefore it is
easy for the user to identify.
• Learnability: - Can use standard icons / buttons to do basic functions.
This will help user to achieve a much better satisfying experience.
• Efficiency: - by allowing user to find songs / playlists according to
certain categories will help user to play the songs that they are
searching for.
d) Translate usability goals in to set of questions.
 Effective to use: -
• How much time does it take to upload one file?
• Maximum number of songs that can be played in a
playlist?
• Maximum volume increase when play a song?
• How much time to take next song play after the current
song?

9. Page | 9
 Learnability
• How much time user spends to perform basic function?
• How many functions user could accomplish without
spending more than 30 second?
• How long time user take to identify the playing buttons?
• Efficiency
• Can you search songs according to the playlist?
• How much time to take search for a particular song from
the playlist?
e) List set of user experience goals that you think will be most relevant. Explain
why.
• Annoying: There are no attractive things in this applications. Such
as small and not meaningful icons, not effective background and
not attractive playing control buttons.
• Entertaining: It use to spend free time for listening to the music
• Supporting creativity: Can introduce sound effects equalizer and
give animated visualization
• Enhancing Sociability: Can introduce some sharing options to
share favorite songs or high rating songs to social medias
f) Translate user experience goals in to set of questions.
 Annoying
• How is the design of the application?
• Do you find any attractive buttons or functions?
Entertaining
• How long time to spend for listening to the music
through the application?
• How many songs add to the playlist in the
application?

10. Page | 10
 supporting creativity
• Do you find any effects for equalizer?
• Do you find any visualization effects?
 Enhancing Sociability
 Can you share favorite songs in social
Medias?
 Can you rate your songs in social
Media?
How the tool has been designed paying particular attention to how design principals
used in existing design.
Design Principle Function
Visibility  Repeat : album, track, playlist
 Volume Control
 Position Slider (slide music
player Timer bar )
 Search
 Create Playlist
 Song Rating (using stars)
 Categorize songs by Artist and
Album wise
 Music Play Bar – play songs,
forward, backward songs

11. Page | 11
Feedback  Shows currently playing song
with album name, author, time
etc.
 Help Menu use to get online
solutions and more details
 Music play bar – which is
highlighted when user press on it
 Notification (Message) – show
currently playing song’s details
when application is minimized
Affordances (Virtual)  Reorder playlist
 Tree view design for left side
category table user need to learn
how to extend and shrink
categories
 Advance Queuing – add song or
album at the end or as next in
playlist
 Reorder songs (sorting songs by
alphabetic, time added etc.)
 Customize the UI design and
color
(Remove extra white spaces, auto
capitalization etc.)
 Equalizer – To Customize the
song’s audio quality and sound
base category

12. Page | 12
Consistency (Internal)  To do similar functions using
short keys (using ctrl + first letter
of function )
E.g. :- for Add directory - ctrl+d
Play net radio - ctrl + R
Consistency (External)  Music Play bar which is different
between different applications in
MusikCube it has all
buttons(play, shuffle, repeat etc.)
but in other application only play,
forward, backward buttons are
available
E.g. :- ITunes
Table 3 : Lab works 3
If you can identify / suggest to use design principals to the existing design, describe what
they are.
1. Visibility: - Use standard icons (more user friendly and understandable icons) for buttons
and standard specific colors for UI design E.g. Playlist, Library, Devices etc.
o Use images for easy to identify the each album or playlist
o Increase the font size and Header size for more visibility and
remove the unnecessary white spaces
o Use larger and effective music play bar. E.g. in side view or top view
Different category
o Use larger search bar, icon and locate the search where it can be easily identified by users
2. Affordance: - reduce the learning things in application

13. Page | 13
o Use symbols to left side category tree view to increase the user friendly (+ or -).
o Give quick guide (using minimum number of steps) to users when they use this
application at first time (Quick Guide Tour)
3. Feedback: - play a sound clip when song is automatically changed in minimized state of
the application
Explain reasons for your suggestions.
1. In the existing design buttons and icons are not in proper standard and kind of similar
design so we need to use new effective design attractive buttons, icons
2. Increase the size of font, labels, headers, Icons and other design stuffs to increase the
visibility
3. Using images to albums and using larger effective dancing music play bar so user can be
easily identify the songs and the music play bar will increase the user UX
4. Reducing affordance is help to increase the user friendliness and reduce the learning
burden no need to spent more time to learning so user can be familiar with this
application easily
5. Quickly tour guide gives quick guide lines to the users about the application so users
easily understand the functionality of that applications

Explain how significant requirement gathering activities to your project.
Requirement gathering is an essential part of any project and project management. Especially
for our project because our project is social, entertainment related thing and also it has wide
range of user levels. Understanding fully what a project will deliver is critical to its success.
This may sound like common sense, but surprisingly it’s an area that is often given far too
little attention.
Many projects start with the barest headline list of requirement only to find later
the customer’s needs have not been properly understood.to avoid these problems. Proper
requirement gathering activities (proper) are very important
Discuss the importance of gathering requirements.
After gathering requirements only we can ensure requirements are specific, realistic and
measurable
Most of the projects are not in standard, which is expected by the user group because
developers assumed the requirements without gather from the relativistic users so we need to
gather it from actual users or related people
After gathered the requirements only we can identify political issues related to the project,
economic and business environment changes, user categories.
We need to have enough consultation with real users and practitioners to get the proper
requirement and get agreed with stake holders before the project starts. And more
consultations are increased the accuracy of gathered requirements.
When we have proper requirement document we can create prototype if necessary to confirm
or refine the customer’s requirement

15. Page | 15
Which goals you plan to achieve through gathering requirements?
To be successful at our requirements gathering and to give the project an increased likelihood
of success we have planned to achieve these goals.
 Involve the users from the start.
 Define and agree the scope of the project.
 Ensure requirements are specific, realistic and measurable.
 Gain clarity if there is any doubt.
 Create a clear, concise and thorough requirements document and share it with the user.
 Confirm our understanding of the requirements with the intended users.
For the Application:
 Define actual users of the application
We are not develop this application from begin. We don’t know who are the actual users?
And what functionalities they really want? So we can get more idea about various audience
groups through gathering requirements.
 Get good user satisfaction design interface (user-centered design)
Our MusikCube application is already exist and someone created the design interface. That is
not satisfied to all the user levels. Because that design interface not have more user friendly.
So that application is not reach all the user levels. So we plan to achieve a good user
satisfaction design interface through gathering requirement from different level users.
 Make sure modifications of the existing functionalities
We can get brief idea about what are the modifications we do in existing functionalities and
how to change that functionalities flexible for different user levels through gathering
requirement.

16. Page | 16
 Prepare new functionalities for the application
In the existing application some new function must want. We don’t know which function
must want by mostly use audience. So we can fix what are the new things add this
application from gathering requirements.
Identify different kinds of requirements relevant to your design project (not requirements
only types)
 Functional Requirement
 Add music file to the app
Our application mostly base on music. So accepts different type of music files
from the device files system and some other external device. At the time user
add multiple files or single files to the app
 Play selected music
When user select the music automatically play that music
 Create a music library
User can create a music directory within the app and store music files inside
the directory
 Search music file
User can search all the possible search (music name, album, artist and lyrics)
for find a music file.
 Find recently play files
There is an option called as recent add. That will help to find resent added
files from the large musical library
 Non Functional Requirement

17. Page | 17
 Portability
Portability is the usability of the same software in different environments. The
pre requirement for portability is the generalized abstraction between the
application logic and system interfaces. MusikCube is a desktop application
so user can’t run without install. Different type users have different
environment devices. So this application must support to various platform.
 Performance
Performance is characterized by the amount of useful work accomplished by a
computer system or computer network compared to the time and resources
used. In the Musikcube Application. High computer performance may involve
one or more of the following
 After user select the song application plays song within 2
second (short response time)
 High throughput (rate of processing to play)
 Low utilization of computing resource(s)
 High availability of the computing system or application
 Security
This is an audio player so only access music files. It doesn’t access other files
from the installed device.
 Data Requirement
 Music Album Information
 Artist / Composer
 Title
 Format

18. Page | 18
 Label
 Catalog number
 Release date
 Genres
 Number of tracks
 Total duration
 Music file Images
 Front Covers
 Back Covers
The whole data of this software package will be stored in a database.
Discuss how you are going to identify user characteristics.
Using the data that has been gathered, you can start building your user groups. As the name
implies, user groups are groups of users who share similar characteristics. There are not specific
users for the MusikCube. These characteristics typically fall into 3 categories:
• Personal: e.g. age range, gender and capacities
• Academic: e.g. education, certification and computer experience
• Attitudes: Attitudes towards the job and the task
The application mainly forces on entertainment purpose therefore it could be used
either for personal, academic or any other way.

Identify requirement-gathering methods to be used in your project.
Requirements gathering are an essential part of any project and project management.
Understanding fully what a project will deliver is critical to its success. This may sound like
common sense, but surprisingly it's an area that is often given far too little attention.
Many projects start with the barest headline list of requirements, only to find later the customers'
needs have not been properly understood.
One-way to avoid this problem is by producing a statement of requirements. This document is a
guide to the main requirements of the project.
An entertainment application like MusikCube can attract any age group therefore gathering
requirements include all types of user groups.
Some of the requirement gathering methods that can be used in the team’s project are:
 Interview: - the team members interviewed certain age groups and made personas
using the details given.
 Researching Similar Products: the team members can find similar products and get
ideas how other developers have portrayed the requirements accordingly. For
example the team is highly motivated by iTunes created by apple development team.
 Study documentation: Procedures and rules are often written down in manuals and
these are a good source of data about the steps involved in an activity and study the
applications user manual and get to know more about the application rules and
standards. Apply them when developing.
 Focus groups and workshops: These sessions can be very structured with set topics
for discussion, or can be un- structured. In this latter case, a facilitator is required
who can keep the discussion on track and can provide the necessary focus or
redirection when appropriate this could be helpful to the team to find multiple user

20. Page | 20
 Observations: - Observation involves spending some time with the stakeholders/
supervisor as they go about their day-to-day tasks, observing work as it hap- pens, in
its natural setting. A member of the design team shadows a stakeholder, making
notes, asking questions (but not too many), and observing what is being done in the
natural context of the activity.
Type Data type Advantages Disadvantages
Researching
similar products -
Qualitative Good for prompting
requirements
Takes a lot of time

4.0. Use Case Diagram
A use case diagram at its simplest is a representation of a user's interaction with the system that
shows the relationship between the user and the different use cases in which the user is involved.
A use case diagram can identify the different types of users of a system and the different use
cases and will often be accompanied by other types of diagrams as well. This is a use case
diagram for Musikcube system.
Figure 1 Use case Diagram

5.0. Use Case Scenario
A use case represents the actions that are required to enable or abandon a goal. A use case has
multiple “paths” that can be taken by any user at any one time. A use case scenario is a single
path through the use case. Our team found some use cases from the use case diagram and
develop scenario for that use cases. There are some use cases given below. After that prepare
scenario for that use cases.

Home page is pretty blank huge white space it should have some really nice colors, background
and images in current people actually prefer attractive and user friendly application because for
the beginners it’s difficult to work it out providing some functionality to user to customize the
application should have some updates continuously so lot of changes to be made

11.0. Proto Type
A prototype is one manifestation of a design that allows stake holders to interact with it and to
explore its suitability; it is limited in that a prototype will usually emphasize one set of product
characteristics and de-emphasize others.
When you hear the term prototype, you may imagine some think like a scale model of a building
or a bridge, or maybe a piece of software that crashes every few minutes. But a prototype can
also be a paper-based outline of a screen or set of screen, an electronic picture, a video
simulation of a task, or a three dimensional paper and cardboard mockup of a whole work
station. This assignment use paper-based set of screens.
Why Prototype important?
Prototype are a useful aid when discussing ideas with stakeholders; they are communication
device among team members, and are an effective way for designers to explore design ideas.
There are two main prototype. Namely
 Low –Fidelity Prototype
 High –Fidelity Prototype
In this assignment use low –fidelity prototype
Low –Fidelity Prototype
A low –fidelity prototype is one that does not look very much like the final product. For
example, it use materials that are very different from the intended final version, such as paper
and cardboard rather than electronic screen and metal.
Low –fidelity prototypes are useful because they tend to be simple, cheap, and quick to produce.
This also means that they are simple, cheap, and quick to modify so they support the exploration
of alternative design and ideas. This is particularly important in early stages of development,
during conceptual design for example, because prototype that are used for exploring ideas should
be flexible and encourage rather than discourage exploration and modification. Low –fidelity

43. Page | 43
prototypes are never intended to be kept and integrated into the final product. They are for
exploration only. There are some reasons using low –fidelity prototype for this assignment
Advantages of law –fidelity prototype
 Lower development cost.
 Evaluate multiple design concept.
 Useful communication device.
 Address screen layout issues.
 Useful for identifying market requirements.
 Proof-of-concept.
