1.What kinds of information and insights did it give you about the usability of the prototype?
The think-aloud technique is very useful in determining the user’s thought processes. It enables them to give direct and spontaneous feedback at every step of the process. I was the designated user to employ this technique while using the Officeworks website. I feel that it was effective in communicating my decision making and explaining the issues that I encountered. When assessing others using this technique, it was easy to follow and led to insights such as them not being able to find certain features. User observation, on the other hand, is more difficult to follow as an evaluator because facial expressions can be ambiguous, and sometimes hard to read when the user is looking down towards the screen. As a user, they are automatic. For this reason, they may be able to expose more genuine insights, and those that are too difficult or transitory to verbalise.
Think -aloud is a very good way to understand the users, from their mindset when using the product to the behavior they had when interacting with it. From recording the words and users’ feeling they told, we could know, from a user’s perspective , how people may look and think of it. From observing the face expression, we could know the pattern they have.
2.What aspects of the technique worked well or were frustrating?
A advantage of think aloud is that it works for both professional tester and non-professional ones. A professional think aloud tester can to do better job, obviously. Howevr, some one who never know what Think aloud is can also perform a test after explainning to them in a short time.
Another pros is that is relatively cheap( the reason is we don’ t need to pay a lot for the tester), and with a certain number of participant, we can get penty of useful information.
The frustrating part is that we might find our participants aren’t really telling us what they were thinking, they tried to act professional and lie. Also, sometimes we tend to lead to the users unconsciouly, when can lead to wrong understanding about the result.
