1) What kinds of information and insights did it give you about the usability of the prototype?

User observation:

User observation is an great techniques for recording the user’s facial expression and non-verbal such as some gestures and body languages.  It should highlighted that as an user, sometimes my expression cannot reflect the experiences I had before. even I haven’t realize I am smiling or I am thinking.

From evaluator’s perspective, the task requires evaluator to observe the process of online ticket reservation from user’s behaviour and what user said.  First-hand information can be collected and analysed throughout whole process, and evaluator can have an better understanding of the user’s empathy and needs.

 

Think Aloud:

Think aloud is the techniques trying to collect the information what user’s inside thinking. To be specifically, the users are encouraged to speak out their thoughts toward the tasks and describe their feelings, which is much actually expressed during the process.Combined with the observation , think aloud could provide detail explanation to the observation, and demonstrate or reflect the user’s experiences for a particular product because they are able to describe the accurate expression of their feelings. Because facial expression is hard to define and hard to catch immediately, therefore, think aloud allows us to directly know the attitudes of the user.

 

2) What aspects of the technique worked well or were frustrating?

It is really hard to find the specific information in the task3, because the font and there are too much information in the pages. The library site cannot easily to find the book based on the requirements.

It should note that think aloud also has weakness, it cannot easily to have understanding of emotions and feelings of users when they have interactive with the prototype.
