For the user observation with think-aloud, comment on how you experienced the technique (as either user, observer or other). What kinds of information and insights did it give you about the usability of the prototype? What aspects of the technique worked well or were frustrating?
As an user, it’s hard to understand the prototypes in the tutorial session because they seems haven’t completed yet. (probably just because not enough time to complete) There were some missing components and not quite sure the correct order of the screens. There are 2 others classmates as an user and we all bit confuse on some components but we couldn’t ask the one who create the screens. I like think-aloud technique because I can give my opinion as much as I can but not only answering questions in survey. Although the screens seems haven’t completed yet, I can understand the purpose of the application with the existing prototypes and visualised the application.
For the heuristic evaluation, what kinds of information or insights did you gain about the usability of the prototype? What aspects of the technique worked well or were frustrating?
By using the heuristic evaluation method, I know whether our design meets the real worlds needs, whether the layout / procedures are easy for the user to understand and any issues in the application. When I prepare the heuristic evaluation form, I could have a chance to double check if the design meets the project goals as well. I can see the user’s opinion on each task easily by the heuristic evaluation form. However the result of the evaluation is very depends on the user’s background / skill / experience. So we should better evaluate with more people.
