Unit 1. Overview of User-Centered Design and Testing

In this unit, we introduce the basic principles of user interface design. We cover two facets of UI design: the construction of interactive programs and the design of their behavior. The latter is grounded on the principles of human psychology and carried out through the techniques of heuristic evaluation and think-aloud user testing.

When you are done with this unit, you should complete the multiple-choice quiz. In addition, you should complete and submit the exercise at the end of this unit (following module 1.3).
