1. Low-fidelity prototype
  2. Conceptual Model
  3. A low-fidelity paper prototype (wireflow) with simple details to give a basic idea of the application.
  4. Detailed Representations
    1. High-fidelity prototype using AdobeXD
    2. Storyboard
    3. Together present when users would use the application and how users interact with it
  5. To visualize the application and see how the system is organized and works
  6. Before the test
    1. PCF
    2. PIS
    3. For ethics issues
  7. During the Test
    1. Facilitator
    2. Prototype Executor
    3. Qualitative data collector
    4. Quantitative Data Collector
    5. Team roles in testing
  9. Identify the usability problems and Improve the prototype based on the feedbacks
  10. Field Study
  11. During the Study
    1. Performance will be automatically recorded by the application
  12. After the study
    1. post-study QUIS questionnaire
    2. optional post-session interview
    3. to get more detailed feedbacks
  13. Before the Study
    1. PCF
    2. PIS
    3. Pre-study tutorial
    4. For ethics issues
    5. help participants install the application and teach them how to use, especially the core functions.
  14. Analyze Data and Feedbacks for further Improvements
  15. Test the functionality of the application and identify the usability problems. Users will be asked to complete several tasks provided and performances will be observed and recorded for evaluation. The whole process lasted for 30 min each participant.
  16. After the test
    1. SUS Questionnaire
    2. More Detailed feedback
  17. Conducted in natural settings to see how application impact users' daily life. The whole process will last for two weeks as planned, however, due to some limitations, only a small pilot study will be conducted instead of the entire study,
  18. Asking for how the application had helped users and what users have learnt from their experiences.
