A Review of Visualization Assessment in Terms of User Performance and Experience

Traditionally, information visualization research tends to focus only on performance related metrics such as task completion time and correctness. However, a recent interest on goals such as memorability, engagement, and fun has also sparked. We propose a reflection on visualization assessment supported by a profound analysis of research that includes user studies of visualization tools and techniques. The motivation for this study is to explore the possible benefits of having a unified standardized metric for usability and user experience that can become a clearer quantitative model of both. Such a metric can provide visualization researchers and practitioners a more succinct and accurate way to assess their visualizations.
