  2. Overview • Overall Problem and Solution • Task Demonstration • Tasks • Design Evolution • Current UI • Final Test • Summary

  3. Overall Problem and Solution PROBLEM SOLUTION

  4. Task Demonstration Difficult – Find the closest Starbucks and order a Grande Vanilla Frappuccino. In addition, add this item to your favorites.

  5. Overview • Overall Problem and Solution • Task Demonstration • Tasks • Design Evolution • Current UI • Final Test • Summary

  6. The Tasks Task 1 – Order a Vanilla Frappuccino Task 2 – Order from your favorites Task 3 – Order for you and a friend

  7. The Tasks Task 1 – Order a Vanilla Frappuccino Task 2 – Order from your favorites Task 3 – Order for you and a friend Why these tasks?

  8. The Tasks • Maximum amount of coverage. • Varying difficulty levels. • Aligned with survey and task analysis results.

  9. Design Evolution How did we get to this point?

  10. Survey and Task Analysis • Match between system and real world

  11. Survey and Task Analysis • Match between system and real world • Map • Proximity is key • Favorites • People order the same things

  12. Low Fidelity Prototype • User Control and Freedom • Error Prevention • Consistency and Standards

  13. Low Fidelity Prototype • User Control and Freedom No way for user to change an order except press the back button.

  14. Low Fidelity Prototype • User Control and Freedom

  15. Low Fidelity Prototype • Error Prevention

  16. Low Fidelity Prototype • Error Prevention

  17. Low Fidelity Prototype • Consistency and Standards Don’t redefine expected behaviors.

  18. Heuristic Evaluation • User Control and Freedom

  19. Heuristic Evaluation • User Control and Freedom

  20. Current User Interface What does it do? How does it work? What is it missing?

  21. Final User Test Online Survey Lab Experiment

  22. Online Survey - Method • Implemented Logging • Tracked time to task completion • Number of erroneous clicks

  23. Online Survey - Results • First task average completion time was 7:10 • Second task average completion time was 0:32 • Third task average completion time was 1:35 What does this tell us?How do we fix this?

  24. Lab Experiment - Method • Observed users as they went through tasks • Used an actual iPhone

  25. Lab Experiment - Results • Most users had trouble with Map page • High fidelity vs. low fidelity issues What does this tell us?How do we fix this?

  26. Final User Test • Online Survey vs. Lab Experiment • Quantitative vs. Qualitative

  27. Summary User experience driven changes Iteratively better product Different stages yield different challenges
