Information Visualization Evaluation

AVIZ published several articles on evaluation. Three are related to Psychophysics studies [44] or perception: “An Extended Evaluation of the Readability of Tapered, Animated, and Textured Directed-Edge Representations in Node-Link Graphs” [23] , “Temporal Distortion for Animated Transitions” [19] , and “A Study on Dual-Scale Data Charts” [11] (see above).

Petra Isenberg has contributed to three articles on evaluation methodologies: The first article “Collaborative Visualization: Definition, Challenges, and Research Agenda” [12] deals with challenges of collaborative visual analytics and includes a discussion on the challenges of evaluating tools during multi-person use. The second article,“Information Visualization Evaluation in Large Companies: Challenges, Experiences and Recommendations” [14] , discusses challenges of evaluating and deploying visual analytics tools in a large company setting. It lists several challenges and provides concrete guidance to others who seek to evaluate tool within domain experts in their work environment. Finally, “Seven Guiding Scenarios for Information Visualization Evaluation” [33] is a pre-print of an journal article (in press) which provides a new viewpoint on evaluation in information visualization. Instead of giving an overview of methods, it cites evaluation goals and questions and can, thus, provide clear considerations for practitioners and researchers in the area.
