Conceptual and Practical Challenges in InfoViz Evaluations
Abstract: Research in information visualization (InfoViz) has developed considerably during the last 25 years. In particular, the field is now informed by a substantial and growing literature on evaluations of visualizations. To keep advancing InfoViz, I believe we need to address two limitations of our evaluations. On the one hand, few empirical studies are motivated by theory or are comparing equally plausible hypotheses. Mostly, the InfoViz literature proposes radical innovations (in the terms of William Newman) and does little to develop and test concepts. On the other hand, many of the practical, low-level decisions in InfoViz evaluations are problematic. Like most HCI researchers, we evaluate our own interfaces, use mostly simple outcome measures, rarely study the process of interaction, and select tasks somewhat randomly. This talk will outline the conceptual and practical challenges of evaluation and begin a discussion of how to overcome them.Biography: Kasper Hornbæk received his M.Sc. and Ph.D. in Computer Science from the University of Copenhagen, in 1998 and 2002, respectively. Since 2009 he has been a professor with special duties in Human-centered Computing at University of Copenhagen. His core research interests are human-computer interaction, usability research, search user interfaces, and information visualization; detours include eye tracking, cultural usability, and reality-based interfaces. Kasper serves on the editorial boards of Journal of Usability Studies, Interacting with Computers, and International Journal of Human-Computer Studies (IJHCS). He has published at CHI, UIST, ACM Transactions on Computer-Human Interaction, and Human-Computer Interaction, and won IJHCS’s most cited paper award 2006-2008.
