1. What kinds of information and insights did it give you about the usability of the prototype?
When the prototype is used, the experience of users will be provided. It may include the feeling of the users or their suggestions on improving the product which provides another perspective from the intended users. Besides, when the users are trying the prototype, the designers can also collect the data including the behavior of both the users and the prototype. Prototype is a kind of practical process unlike the interview or questionnaire which means it provides the information and insights from the practical and reality perspective.
2.What aspects of the technique worked well or were frustrating?
As the user, I was guided and told what to do by a person, this technique works well, however, I was trying to meet the target of the experiment which was a little frustrated me.
As an evaluator, I felt hard to observe the user meanwhile keep recording the data.
