Think Aloud -- Mengdi Huang

In order to identify potential usability problems of interaction design products, think aloud helps designers to know the thoughts of users by letting them say what they are thinking when conducting a certain task by product. Since our product has no complex functionality, the task is simply successfully create a postcard. There will still be some silent moments, due to people's customs. Despite of this, designer can capture users much preciser than imagining.

Pros:
Good to have a brief tutorial

Map taking place of list is interesting

Cons:
Tutorial is a bit boring
Buttons not so obvious

A little confusing when first see the pins on map
Too many spots to choose. Annoyed to click each of them to see which is the best. And forget which one has been clicked.

Stickers are not enough.
Stickers are not adjustable in size or angle.
                 

Didn't know how to get video clip until the postcard is printed out.
