An introduction and guide to evaluation of visualization techniques through user studies

Abstract

The objective of this chapter is to increase awareness of what constitutes a sound scientific approach to evaluation through user studies in visualization, and to provide basic knowledge of current research practice relating to usability and evaluation. The content covers the most fundamental and relevant issues to consider during the different phases of an evaluation: Planning, design, execution, analysis of results and reporting. It outlines how to proceed to achieve high quality results and points out common mistakes during the different phases and how these could be avoided. The chapter can be used as a guide when planning to conduct an evaluation study. The reader will also learn to better judge the relevance and quality of a publication presenting an evaluation when reviewing such work, since the same guidelines apply.
