PROBLEM SOLUTION
Task Demonstration
Difficult – Find the closest Starbucks and order a Grande Vanilla Frappuccino. In addition, add this item to your favorites.
Overview
Overall Problem and Solution Task Demonstration Tasks Design Evolution Current UI Final Test Summary
• Task 1 – Order a Vanilla Frappuccino• Task 2 – Order from your favorites• Task 3 – Order for you and a friend
The Tasks
• Task 1 – Order a Vanilla Frappuccino• Task 2 – Order from your favorites• Task 3 – Order for you and a friend
The Tasks
Why these tasks?
The Tasks
• Maximum amount of coverage.• Varying difficulty levels.• Aligned with survey and task analysis results.
Design Evolution
How did we get to this point?
Survey and Task Analysis
• Match between system and real world
Survey and Task Analysis
• Match between system and real world• Map
• Proximity is key• Favorites
• People order the same things
Low Fidelity Prototype
• User Control and Freedom• Error Prevention• Consistency and Standards
Low Fidelity Prototype
• User Control and Freedom
No way for user to change an order except press the back button.
Low Fidelity Prototype
• User Control and Freedom
Low Fidelity Prototype
• Error Prevention
Low Fidelity Prototype
• Error Prevention
Low Fidelity Prototype
• Consistency and Standards
Don’t redefine expected behaviors.
Heuristic Evaluation
• User Control and Freedom
Heuristic Evaluation
• User Control and Freedom
Current User Interface• What does it do?• How does it work?• What is it missing?
Final User Test• Online Survey• Lab Experiment
Online Survey - Method
• Implemented Logging• Tracked time to task completion• Number of erroneous clicks
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?
Lab Experiment - Method
• Observed users as they went through tasks
• Used an actual iPhone
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?
Final User Test
• Online Survey vs. Lab Experiment• Quantitative vs. Qualitative
Summary• User experience driven changes• Iteratively better product• Different stages yield different challenges
