this module. If coursework is submitted late (and where there are no extenuating
circumstances):
1 If the assessment is submitted no later than 24 hours after the deadline,
the mark for the assessment will be capped at the minimum pass mark;
2 If the assessment is submitted more than 24 hours after the deadline, a
mark of 0 will be given for the assessment.
Your submission must include the official Coursework Submission Cover sheet, which can be

Q1
Virtual meeting applications (such as Zoom, Teams, Webex, Blackboard collaborate, etc.)
have become essential working and social communication tools. There are many
applications on the market, and all compete for users.
In this assignment you will consider the design of one of these tools and write a heuristic
evaluation report on the usability of its interface.
Q1. Part 1: User and Task Analysis (10 marks out of 20)
a. Choose one example of these applications. You can choose to consider a web
interface for the application or a mobile version of it.
Identify and describe One primary Persona for your application. Include all
components of the persona description, as discussed in the lectures.
Note: Applications can serve a wide variety of users and as such, may have multiple
primary personas. The persona you choose will guide your consideration for the
subsequent steps in this exercise. ((3 marks out of 10))
b. Identify and describe one primary and one secondary tasks/use cases in the system
(primary tasks are important and frequently used functions by your primary persona,
secondary tasks are desirable but are of less importance to your primary persona
than primary ones). For every use case, provide a brief (text) description and the
outline of the steps in its basic flow scenario and Two of its alternative flow
scenarios. ( (3 marks out of 10))
Note: Tasks such as Register/Login are not primary use cases. These are
supplementary functions to allow a user to access the primary function of the
system.
c. Produce Two State Transition Networks (STNs) to describe the interaction flow in
your use case scenarios (for the basic and alternative flows in each use case).
Use an abstract depiction of the screens with no detail on design elements of the
interface. Your STNs need only depict states and user actions between states in the
use case scenarios. ((4 marks out of 10))
Note: Generally speaking, an interface state changes when an event occurs. For
example, an entry of text in a text field, a click of a button, etc. Your STNs need to
depict all possible states of interaction in the use case scenarios.
Q1. Part 2: Heuristic Evaluation (10 marks out of 20)
For every use case, do a heuristic evaluation of the individual states of the interface,
identifying all usability issues.
Report on the usability issues in an objective manner and present the issues in a
systematic and standard format using the templates (Excel spreadsheet) provided and
discussed in the lectures. Your report should include,
a. the usability problems you identified with some justification of the severity score
assigned to the problems and your suggestions for addressing the issues you
identified in subsequent revisions of the interface, (5 marks out of 10)
b. the good design features that should be maintained in any subsequent revision of
the application. (5 marks out of 10)
Learning Outcomes Assessed
1. Understand the complex nature of users and apply heuristics to create and evaluate
inclusive and multimodal user experiences.
2. Evaluate competing proposals for interface design and implementation.
3. Apply human centric design methodologies in the context of current and emerging
interaction technologies such as virtual and augmented reality.
