    User Centered Design (UX) • UX is a rhetorically based

    philosophy of design that considers users’ needs and wants and limitations when designing a product. 2 If you don’t consider my needs and wants, then I won’t want to use your product.

    Usability Testing (UT) UT is a method for finding out

    if a product works for users. 3 I feel the designers could make this product more convenient for me to use. You aren’t the user dummy. I am and it works fine for me as long as you aren’t around.

    Types of Usability Tests 10 • Lab based testing involves

    recruiting participants and observing their behavior as they do a series of tasks. Often involves video-taping the user and several observers. • Survey testing involves asking users of a product to respond to a series of questions about their user experience. • Cognitive walkthrough involves an evaluator who does a set of specific tasks rather than the actual user. The idea is for the evaluator to assume the role of user.
