The defense allows you to present your prototype, and to report about your evaluation of the HCI (see "Prototyping stage" and "Evaluation stage" in the Expected work). In particular, you present what you learned thanks to the experimentation and, more generally, what you learned in the project.
The defense usually has the following structure:
- You (quickly) remind the context: the problem you are addressing, its importance, and your global approach.
- You present your prototype, and in particular you discuss its strengths (compliance with your design) and limits (non compliance).
- You present your evaluation:
- The questions for which you sought answers with the evaluation.
- How you did the evaluation (practical details).
- The main statistics about recorded data.
- How the evaluation questions your design.
- You conclude
- On what you learned: facts, lessons learned, and conclusion about the relevance of your approach and the requirement for a next iteration on the design.
- On your view about HCI engineering, such as the overall process, the results, and the organization of the work.
