Think-aloud Evaluation

Think-aloud is a technique where users interact with the product in order to be observed so that the researchers can test the usability goals and user experience goals of a design.

I asked a fellow student to perform the think-aloud evaluation since she can also be viewed as an international tourist.

Prior to the evaluation, we did not specify the functionality of this app, but to see how well she can make use of the tutorials to also evaluate the placement and clarity of it.

Below are the stages of evaluation.




On the introduction page: 

 "Those portrait slides illustrate this app is for snapshots."
"There are two buttons, one for going straight ahead, the other for reading instructions."
"The text below are not showing completely." [We edit that part later]

("By clicking the 'tutorial' button, we go to the tutorial page. ")


On the tutorials page: 



“The tutorials seem clear enough.”
"Too many texts with no pictures though."
"Also it would be lovely to add a 'go straight ahead' button, so we don't have to go back to intro page."[There is a link to the map page now.]

("By clicking 'back to home' button on the upper right corner to go back to into page, and then 'go ahead' on the home page, we go to the map page. ")

On the map page: 



"The explanation seems clear. "
“There is pan function for the map so we can see all the pinpoints on the map. ”

("By clicking one of the pinpoints, we go to a scenery page. ")


On the scenery page: 



"There is a short description for Vasa Museum."
"Also multiple scenes to choose from. "

("By clicking the 'apply' button, we go to the video capturing page.")


On the video capturing page: 



“By clicking the start button, we see a demonstration of an AR video”

("When the video capturing ends, it will automatically switch to snapshot page")


On snapshot page: 




“This page shows several snapshots, and there is clear instruction for how to choose from them.”

("By clicking 'confirm' button, a green 'print' button appears on upper right corner, and we click that to go into the sticker page.")



On sticker page: 



“This page has a menu to choose stickers from, which is nice. ”
"However, one can only use one sticker for a single time."
"It would be better to add more options. "

("Once we are happy with the decorations, we click the 'print' button to go to the printing process.")

On waiting for printing page:
