Interface Design and Implementation - Computer Science Assignment Help

Assignment Task

Q1. Part 1: User and Task Analysis

a. Identify and describe Two primary tasks/use cases in the system (important and frequently used functions by your primary persona). Provide a brief (text) description of the task/use case and the outline of the steps in the basic flow scenario and the alternative flow scenarios of the use case.

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.

b. 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. 

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

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,

b. the good design features that should be maintained in any subsequent revision of the application. 

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.
