Introduction – Pomodoro Technique

• Francesco Cirillo• Helps you stay focused and concentrated• Plan the Day• The process:

1. Choose a task to accomplish2. Set the Pomodoro timer to 25 minutes3. Work until timer rings4. Take a short break5. Every four Pomodoros, take a longer break

Methods for Interface Design – User TestingMethod:• Testing using paper prototypes• Users were given limited background knowledge• Unexpected behavior was noted

Results:• Everyone prefered tab design• Positive aspects of toolbar design• Problems understanding activity priorities

Conclusions & Lessons Learned

• Use common iPhone interface patterns as much possible

• Customizing is much harder• Use Apple guidelines for interface design• Use Interface Builder wisely• Don’t rely too much on the simulator
