After having conducted a prototype interview, I realized what a powerful tool it is when used correctly. By being used correctly, I mean: identifying tasks that need to be tested; creating sketches that allow users to think critically about the interface; formulating tasks in an unambiguous way; and, finally, taking notes extensively.
As a group, we tried to identify features in Google Maps that could be changed and tasks that could be performed on our proposed interface. Personally, I tried to take as many notes as possible. However, I think that the sketches and task wordings could have been better, but, overall, the prototyping activity was pretty fun and not as hard as I had imagined.
Therefore, there is still room for improvement in our design, which became obvious after the interview (respondent’s confusion with using the interface and the time it took him to complete each task).
