3 Discussion Learned from Pilot Run, Possible Future Improvements 25
Learnings from Testing ● Better to have an actual Android phone ● Screen recordings can be corrupt ● i. Phone video recording would be more helpful in a quieter environment 26
Future Improvements ● Information should be geared towards preferences, see more of the current environment ● Being able to always see your preferences ● Know what the environment looked like ● More preferences ● UI Changes 27
Summary ● Tasks were straightforward but some subtasks were confusing to do ● Need to address this in our future iterations ● Can improve a lot on our experimentation methods 28
THANKS! Any feedback? 29
