Information visualization is a very applied field that prides itself on its practical applications and real-world scenarios. Ignoring the theoretical side is dangerous, however, because it limits our ability to distill useful information about the foundations of the field from the practical work being done, and limits our understanding of how and why our own creations work. The goal of this workshop at VisWeek 2010 is to bring together researchers interested in the theoretical aspects of visualization, define the field, discuss ideas and approaches, and get the word out about the importance of theoretical research in information visualization. Topics include: * Perceptual research * Design studies * Ways of systematically exploring the visualization design space * Methodological work: how do we do our work, and how can we improve our processes? * Representation, structure, metaphors: how and why do we attach meaning to visual shapes? * Reference datasets and tasks Also, how do we make it easier to publish this kind of work? What makes for a good theory paper? Can a theory paper stand on its own, without an application or immediate use? Etc. The workshop will be based mostly on discussions. We invite speakers to submit short (2-page) position statements. A small number of these will be invited to give very brief (3-minute) presentations at the workshop. The goal is not to present large bodies of work, but to have the presentations spark discussions. Deadline: *September 13, 2010 * Submit your 2-page position paper by emailing it to infovistheoryws@me.com <mailto:infovistheoryws@me.com> For more information, a link to the formatting instructions, etc., please see http://eagereyes.org/infovis-theory-workshop Robert Kosara T.J.
