1.What kinds of information and insights did it give you about the usability of the prototype?
Firstly, the usability test is divided into well structured with clear instructions, which make the test proceed much more smoothly. The observation is quiet a interesting work since we need to focus really carefully on user’s face to understand their difficulties, but it is kind of difficult to quickly capture every detail. The video taping helps reviewing the process, but it is not easy to capture both user’s face and their action and response to the app/web. What we did is use some screen recording software, like screen flow to capture the screen and computer camera, by doing this, we can easily connect user’s feedback and the specific action/function. The thinking aloud is a very useful tip.
2.What aspects of the technique worked well or were frustrating?
The thinking aloud is a very interesting technique, at first I thought it might not work since people are not used to do this, but after the testing, I found this is definitely a good technique to understand the real thoughts of users. However, one thing i am concern is whether the thinking aloud will affect the users’ real response, since it will procrastinate the response action time, so it may has some negative effects on products that require user’s quick response or feedback. (like game, shopping).
