Abstract

This chapter deals with the quality assurance part of HCI, evaluation and usability. Different types of evaluation are reviewed and quality definitions of HCI as usability and utility are described. These are related to design principles encountered in Chapter 2. First, the HCI definition of quality, i.e. learnability, memorability, effectiveness and flexibility, is reviewed. This review is followed by description of usability evaluation, that is the testing process for user interfaces. Evaluation may either aim to check that an interface has achieved some standard of benchmark, or be targeted as design improvement via diagnosis of usability errors.
