Scientific Evaluation in Visualization

The objective of this half-day introductory tutorial is to increase awareness of what constitutes a sound scientific approach to evaluation in Visualization and to provide basic theoretical knowledge of and practical skills in current research practice. The content presents the current challenges and trends related to how to characterize and optimize the complex interactive visual displays present in Visualization today. It will cover the most basic and relevant issues to consider during different phases of evaluation: planning, design, execution, analysis of results and reporting. The content outlines how to proceed to achieve high quality results and point out common pitfalls and mistakes which are threats to high quality results. The main focus is on quantitative experimental research but the general knowledge applies to all kinds of studies. The tutorial will present the main part of the content by means of a lecture style using power-point presentations, and will use example studies
