USABILITY ENGINEERING
Nature of
Exam : Open Book

Duration : 3 Hours
Date of
Exam : 22/04/2018 (AN)
Note:
1.
Please follow all the Instructions to Candidates given on the
cover page of the answer book.
2.
All parts of a question should be
answered consecutively. Each answer should start from a fresh page.
3.
Assumptions made if any, should be
stated clearly at the beginning of your answer.
Q.1.
There is a command-line based
function, diff:
diff file1.txt
file2.txt > diffs.txt
This command
compares a text file file1.txt with a second text file file2.txt and outputs a
list of all lines that contain any
differences to a third file, diffs.txt.
As part of a
design team considering developments to a desktop graphical user interface
(e.g. Windows), you have been tasked to implement this function. Outline TWO
distinct design solutions. You should use sketches or diagrams where
appropriate and justify your solutions.
[6]
Q.2.
What is the role of prototype
in usability design? Design user interface for a ticket booking system to sell
train tickets and make this system as unusable as possible, however a very
determined user should be able to buy a ticket if s/he works hard. Justify your decisions. [6]
Q.3.
Explain, with the aid of
diagrams, what is meant by the following website navigation schemes: (a) Linear
(b)
Hierarchical
(c)
Matrix
List weakness of
below given website structure:
Redesign the
navigation of this website using a more efficient scheme, and represent this
scheme by redrawing the navigation diagram, explaining BRIEFLY the key changes
that have been made.
[6]
Q.4 (a) How could you as a designer make use of users’ prior experience and
existing knowledge?
Explain with an appropriate example.
[3]
Q.4 (b) Assume you are a
member of a large software development team.
(i)
How could you involve users at
an early stage in systems development?
(ii)
What problems and attitudes
might you encounter?
(iii) How would you get users practically involved, and when? [3]
Q.5. The digital design company for which you work has landed the
contract to design and build an engaging app to promote latest James Bond
movie. Your responsibility in the development team is to test and evaluate the
interface in terms of the user experience. This includes the usability of the
interface, but also covers compatibility of the design in terms of market and
user demographics and the overall look and feel of the movie.
(a)
List and briefly describe three
different types of QUANTITATIVE evaluation data that you could collect to test
the interface.
(b)
List and briefly describe three
different types of QUALITATIVE evaluation data that you could collect to test
the interface.
(c)
Outline the structure of a
suitable test plan for evaluating this interface. Your answer should consider
the test environment, the protocols for data collection, the kinds of data you
will collect and how the data will be useful to the design team. [6]
Q.6. Interaction designers advocate the development of interfaces based
on recognition rather than recall.
(a)
Differentiate between
recognition and recall in this context.
(b)
Modern interaction is typically
by means of graphical user interfaces (GUI), as opposed to command line
interfaces (CLI). Explain the ways in which a GUI embraces the principle of
recognition rather than recall.
[5]
Q.7. List and describe various visual design principles to be considered
for developing better usability design. How well does below UI communicate? Can
you make it communicate more effectively?
More natural and friendly? [5]
Q.8. The University has a policy that all students must have new iPads
for a specific course. From the perspective of an Interaction Designer, how
would you apply a recognized design method to the process of designing a
suitable application for students to use to access local university information
and to participate in a wide range of class and campus activities? Provide
mock-ups of
your design
solution. Briefly critique your design. [5] ***********
