Measuring the effect of usability mechanisms on user efficiency, effectiveness and satisfaction

摘要

In this paper we present the results of two experiments designed to evaluate the impact of particular usability mechanisms on software system usability attributes. It focuses on mechanisms that human computer interaction (HCI) and software engineering (SE) researchers regard as having a major impact on software development, like undo/cancel or provide feedback. The experiments were run using two different software applications that we developed specially for the purpose. From the results, we conclude that the inclusion of different usability mechanisms has a positive impact on the usability attributes of efficiency, effectiveness and satisfaction.
