Element 1
Title: Evaluate the given system in terms of usability and user experience goals, and interaction design principles.
Task details
You will be responsible for the evaluation of a specified interactive system (see Appendix). You should become familiar with the design problem.
Sub Task 1
Based upon your understanding of Chapter 1 of the Interaction Design textbook (Preece, Rogers and Sharp), choose five usabilities and/or user experience goals which you think will be useful in evaluating the functions take me somewhere and the flight information. You must choose at least two usability goals, and two user experience goals in the five you will discuss.
The usability goals must be drawn from effectiveness, efficiency, safety, utility, learnability and memorability. The user experience goals must be drawn from satisfying, enjoyable, fun, entertaining, helpful, motivating, aesthetically pleasing, supportive of creativity, rewarding and emotionally fulfilling.
Write a short paragraph for each goal you have chosen for each task (10 paragraphs in total), justifying why the goal is particularly important to these designs. Your justification must take into account the purpose of the applications, the characteristics of the users and the types of information that is gathered by the application. Your justification should demonstrate a clear understanding of that goal – a definition of the goal on its own will not suffice.
For each goal justified, include a plausible measurable usability and user experience criterion.
Sub Task 2
There are six design principles described in Chapter 1 of the Interaction Design textbook (Preece, Rogers and Sharp)
Visibility Feedback Constraints Mapping Consistency Affordance
Draw a low fidelity prototype for the tasks of taking me somewhere reflecting the usability and user experience goals discussed in Sub Task 1 for that part of the system. As you produce your user interface, indicate clearly how each of the six design principles is being followed by referring to particular user interface controls and associated behaviour. You should illustrate through different ‘screenshots’ or in storyboard format how visitors will interact with the robot.
| Learning outcomes | LO 1 Understand and demonstrate the ability to apply principles from human-computer interaction to interactive systems design. LO 2 Evaluate interactive systems quantitatively and qualitatively for their ease of use by target customer groups. LO 4 Understand and demonstrate the ability to apply the principles of user interface design and information architecture to trans-mediated and multimodal interactive systems. |
