Human Centric Computing Assessment Number: 1 This assignment is worth 100% (Q1: 33%, Q2: 33%, Q3:34%) of the total marks available for 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 found here:

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. Criteria for assessment
Credit will be awarded against the following criteria.
