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
