Mobile App Design: Usability, UX, Principles and Assumptions

This assignment focuses on the design considerations for a mobile application, emphasizing usability and user experience. It begins by explaining the rationale behind the chosen design concept and discusses key design principles such as simplicity and order, highlighting their importance in creating intuitive and efficient user interfaces. The assignment also delves into assumptions about the target users and their intended use of the mobile app, referencing a case study. It further explores the components that contribute to achieving desired usability and user experience goals, stressing the importance of consistency and simplicity in presenting information. The solution references the Dhillon Party Finder app as an example, explaining its login form and account section features. The importance of keeping the design simple is highlighted to prevent user distraction. The assignment concludes with a bibliography of cited sources.

Design considerations

Describe why your design concept was chosen. (10 marks)
(i) Discuss design principles you intend to use in your design. Explain why you
chose these design principles.
1. Simplicity.
Present the minimum amount of information to achieve maximum effect. Simplicity leads to
quickly recognized and understood functionality. Less information means less time to process
and this can help the user to more quickly produce correct mental models (GALITZ &
WILBERT, 2007). Simplicity also aids recall because there is less to remember and so easier to
recall.
2. Order and structure
Structure doesn’t occur naturally, it must be explicitly created, designed. People will find order
and structure, even if none was intended. Don’t just throw elements into a user interface. A
design needs to explicitly create the structure. At the back of your head you should consciously
consider what placement and arrangement communicates to the user BLAIR-EARLY &
ZENDER, 2008).
Individual elements are associated more strongly with nearby elements than with those further
away. For instance, Spacing stars more closely vertically gives an impression of columns;
spacing more closely horizontally gives an impression of rows.
(ii) Discuss your assumptions about who are your users and how they intend to
use the mobile app to do the tasks set out in the case study.
(i) Our visual system is biased to perceive continuous forms rather than disconnected
segments.
(ii) Elements arranged in a straight line or a smooth curve are perceived as being more
related than elements not on the line or curve.
Summaries design decisions (10 marks)
(i) Discuss the components resulting in your desired usability goals and user
experience goals.
There are many design principles that one can consider. Utilizing all these design principles is
needed to developing a great presentation. However, being consistent and keeping it simple are
most important because it provides the audience a clear and complete understanding of what you
are trying to convey (Heim, 2008). Some information do not require visuals because this allows

the reader to stay on track with the content of the report and not get lost in the information shown
in images.
(ii) Quality of forum interaction (10 marks)
Keeping the design simple is best when you are trying to present key facts. Too many visuals
can take the user off in another direction as explained by (Banga, 2011).
Dhillon Party Finder login form is made in a way that a user can login by using both
Facebook Login and Google Login. A new user is able to click on the sign up button which takes
them to a sign up screen where they enter their names, email address and phone number.
Once logged in the account section, one has the option to log out, edit their account details,
and see their booking history.
The Finder option in the account section, one can enter their specifications of what they want
to find and click on the find option.
