Prototype & Evaluate

In the Design phase of the project, you created 2 different alternatives and made low-fidelity prototypes of them. In this phase, you will create a high-fidelity prototype (running on a computer, allows realistic user interactions) for each of your 2 different design alternatives. There are a variety ways in which to create such a prototype (see the discussion on this topic ): use the one with which you are most comfortable.

Think about the DECIDE framework as you create materials for a user study of your alternative interfaces. Based on the scenario that you used for your design, create a script that you will read to each "tester" and an instrument for collecting the data (what you will measure, what questions you will ask) that you will need to help you choose the better interface once all testing is done.

Everyone in your group should run 1 test and be the tester for 1 other group.

Analyze your results, recommend one of your interfaces for development, and explain your rationale.

Finally, reflect on the process of this project and describe any insights you have gained about your project in particular and interaction design in general. Would you have done some things differently? If there are different opinions in your group, please capture these differences in your document.

This part of the project is worth 10 marks, with the following distribution.

Criterion & Weighting Excellent (3/3) Satisfactory (2/3) Poor (1/3) Unacceptable (0/3)
High-fidelity prototypes (4) Task interface complete, handles all input gracefully. Task interface mostly complete, handles most input gracefully. Task interface somewhat complete, handles some input gracefully. Task interface not complete, does not handle input gracefully.
Usability Tests (4) Test well-scripted and data carefully gathered. Test scripted and data gathered. Test somewhat scripted and data gathered. No script and data carelessly gathered.
Analysis (1) Thoughtful and thorough analysis and reasoned selection of better interface. Analysis and reasoned selection of better interface. Little analysis and little reasoning in selection. No winner declared or basis for declaration not clear.
Reflection (1) Abundant evidence of reflection on the interaction process. Evidence of reflection on the interaction process. Some evidence of reflection on the interaction process. Little to no reflection on the interaction process.
