This learning unit intends to give students knowledge about the basic principles and rules for designing and developing usable user interfaces. This includes learning the iterative development cycle of an interface, starting from the identification of the users and the tasks they want to accomplish, the prototyping techniques and the identification of the best evaluation technique to be applied according to the project phase.

User Interfaces
User Interfaces Design

At the end of the learning process in this learning unit, students should be able to:
- Identify and apply the steps of the iterative development cycle;
- Discriminate the meaning of good and bad interface design;
- Recognize the basic principles and rules for creating interfaces and how to apply them;
- Apply methods to involve users in the development of the interface;
- List the various types of evaluation and know how to apply them correctly.
