Lab 4.3 User Interface Usability

Lab Objectives

After this lab, you will be able to:

  • Understand Usability and Usability Measures

  • Apply the Basics of User Interface Evaluation


Usability is an assessment of the impacts of specific user interface design decisions upon the ease of use of the interface. For evaluating usability, it is necessary to consider the relationships between the product and its users in the first instance. However, we must not forget the other people who interact with the users, other systems, and devices. In other words, we must take into account the complete work environment.
