7. Lab: Usability Testing & Fachgespräch 2

Estimated time to read: 12 minutes

In this lab, you will conduct usability tests on your app, document the findings, and prepare Fachgespräch 2.

You will find further instructions and hints in Usability Evaluation.

7.1 Preparation

Ensure that everything outlined in the preparation section is fully finalized.

7.1.1 Usability Evaluation

Your team is required to conduct a comprehensive usability evaluation of your application. This evaluation will help identify areas for improvement and ensure your application meets user needs effectively.

One team member performs a cognitive walkthrough of your application.
Another team member conducts a formal heuristic evaluation.
Conduct a minimum of two thinking-aloud tests with participants from outside the course.
Accessibility Evaluation
- Utilize appropriate accessibility assessment tools: e.g. Wave or Accessibility Scanner.
Document everything in an Report.

Document your evaluation report in: docs/usability-evaluation.md

The usability report does not need to be very long.

A clear and structured report of about 2–3 pages is absolutely sufficient.

Document your final reflection in: docs/reflection.md

no fixes

You are not required to implement fixes for the identified usability issues. In fact, please avoid doing so, as it may complicate the tracking of findings in your report.

7.1.2 Project Video

Create a 1-2 minute video showcasing your app, highlighting key features, interactions, and possible usability improvements. Upload the video to Nextcloud.

7.1.3 Fachgespräch 2 & Presentation

Final presentations will take place during the lab and selected lecture slots to allow enough time for questions and feedback.

48 hours before your Fachgespräch 2, please submit a short individual reflection in Moodle.

Format per team:

One shared notebook
2-minute live app demonstration
2-minute presentation per team member (1 slide each), highlighting one compelling aspect of your implementation and/or usability evaluation
Fachgespräch 2

Note: Do not include your video in the presentation. Videos will be watched together during the final lecture — make sure your app is running on two mobile devices for that session.

7.1.4 Repository Submission Deadline

Please note that the entire repository content will be frozen at the following times

Your project will be evaluated based on the criteria listed in Moodle.

All repository content must be finalized before the deadline. No changes will be accepted after the freeze time.

Should you have any questions regarding the submission requirements, please contact me promptly.
