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

The most insightful thing this practice gives me is that, by observing,  I am able to build up a profile of the website’s usability both from my personal and other user’s experiences. Despite of thinking aloud, never do I know that recording emotional feedback could contribute to the usability of the prototype. And it turns out works well. A simple frown tells directly that there is a problem occurs when using this website. While as for ‘thinking aloud’, it is somehow like a brainstorming. Users speak out their opinions their thoughts when they are using the website. But the difference is this method based on real experiences.

  • What aspect of the technique worked well or were frustrating?

Taking record of a user’s emotional reaction gives observer an instant feedback of the product. It easily enables observer to gain an empathy with users. The frustrating thing is, such record could only be done by manually instead of automatically, which surely will take a long time and great efforts to give a general feedback of the usability of the prototype. Moreover, different people might have different interpretation of facial expressions. Thus, without a standard definition of the facial expression, it might leads to a misunderstanding if verbal expression or other research methods are not coming together.
