http://geoanalytics.net/ica/icc2013et/ :: ICC 2013 in Dresden NEW CALL ICA Commission on Cognitive Visualization ICA Commission on Geovisualization ICA Commission on Use and User Issues International Cartographic Conference 2013: Pre-Conference Workshop :: Eye tracking: why, when, and how? 23 (noon)-24 (all day) August 2013 @ the Technical University in Dresden, Germany We cordially invite you to participate in a hands-on workshop on how to efficiently and effectively collect, analyze, and make sense of eye movement data in empirical user studies. We will work hands-on with real eye-trackers and real data during the workshop, and discuss issues in the group. This workshop is intended to bring together a broad mix of researchers interested in eye movement data collection methods, ranging from the eye tracking novice who might wish to learn more about this empirical technique, to the seasoned eye tracking expert who wishes to share advanced analytical approaches with other like-minded empirical researchers. Part of the program will use parallel tracks to meet the needs of both novices and experts, and a ‘data challenge’ will form a key component of the meeting. We thus encourage various avenues for involvement in this hands-on workshop, and call for the following contributions: .. Short papers involving ~ Case studies and applications ~ Work in progress reports ~ Open problems ~ Demos and tools ~ Novel analysis techniques and methods .. Responses to our data challenges ~ the organizers provide real eye-tracking datasets, together with analytical tasks by early December 2012. Three different data sets for the data challenge are available. .. Different data sets and their descriptions are available here: ~ CogVis | https://www.geo.uzh.ch/microsite/icacogvis/icc13_dc.html ~ Geovis | http://geoanalytics.net/and/papers/vast2012em/data/index.html ~ UUI | http://www.univie.ac.at/icacomuse/index.php?title=Data_challenge Participation cost: 40 EUR (lunch on the first day is included in the workshop fee) We expect your abstract containing a statement of interest, including the type of proposed contribution (ca. 1 page, PDF or MSWord) by FEB 1 2013. Please send your contributions to: icacogvis(a)geo.uzh.ch (Subject: ICC13) Notifications of acceptance: MAR 1, 2013. Details about workshop, registration etc. will be published here, as they become available: https://www.geo.uzh.ch/microsite/icacogvis/activities.html Further questions can be directed to the commission chairs: Sara Fabrikant (sara at geo.uzh.ch), Gennady Andrienko (gennady.andrienko at iais.fraunhofer.de), and Corné van Elzakker (elzakker at itc.nl).

CfP: IVI Special Issue on Visualization Evaluation
by Petra Isenberg 04 Dec '12

**Visualization Evaluation** *A Special Issue of Information Visualization,* Guest Editors: Enrico Bertini, Petra Isenberg, Tobias Isenberg, Heidi Lam, Adam Perer. ------------------------------------------------------------------------ Visualization has recently gained much relevance for its ability to cope with complex data analysis and communication. Thanks to its ability to convey complex concepts in an efficient manner it has been adopted in many contexts; from scientific laboratories to newspapers. While the overall use of visualization is accelerating, the growth of techniques for the evaluation of these systems has been slow. How do we measure the quality of a visualization? How do we decide on competing designs? How do we know whether a visualization meets its goal? These are only some of the questions researchers and practitioners are confronted with when designing visualization systems. To understand how, when and why visualization works, evaluation efforts should be targeted at the component level, the system level, and the work environment level. The commonly used evaluation metrics such as task time completion and number of errors, when used in isolation, appear to be insufficient to quantify the complex quality and usage of a visualization system, therefore new metrics and methods to better evaluate visualizations are needed. This special issue calls for innovative ideas about how to evaluate visualization and reflections about its state of the art. We call for papers dealing with evaluation in the fields of scientific visualization, information visualization, and visual analytics. We explicitly discourage submissions describing exclusively the process and outcome of a given evaluation unless the methodology itself is innovative. Topics include, but are not limited to: * Evaluation in the visualization development lifecycle * Utility characterization * Evaluation metrics * Insight characterization * Synthetic data sets and benchmarks * Taxonomy of tasks * Computational evaluation * Benchmark development and repositories * Methods for longitudinal studies and adoption * Evaluation of early prototypes * Evaluation heuristics and guidelines * Evaluation of storytelling visualization * Evaluation of visualization as art Paper Submission Submissions due: Feb 8, 2013 Acceptance notices: Apr 15, 2013 Final revisions due: May 13, 2013 Publication: late 2013 Inquiries should be made to the guest editors by sending an email to chairs(a)beliv.orgElectronic submissions of manuscripts in PDF should be made using the online submission system and the papers should be formatted according to the journal standards. For details on the submission process, please visit the Journal's instruction website at: http://ivi.sagepub.com/ -- Petra Isenberg, PhD Research Scientist AVIZ group | INRIA Saclay Île-de-France phone: +33 16 91 54 249 |http://www.aviz.fr/~isenberg/

Postdoc in Infovis/Visual Analytics, University of Washington, Seattle
by Cecilia Aragon 04 Dec '12

04 Dec '12

Postdoctoral Opening in Information Visualization/Visual Analytics, University of Washington The Department of Human Centered Design and Engineering (HCDE) at the University of Washington has an opening for a postdoctoral researcher to perform advanced research and development in the areas of information visualization and visual analytics. The long-term goal is to develop a better understanding of the use of visual interfaces in analyzing and exploring large, dynamic text-based data sets and networks. This work will involve developing new algorithms to visualize networks and text. Modeling of the visual interface and the nature of human-computer interaction over large data sets may also be involved. The work will be performed as part of an interdisciplinary team of students and faculty with expertise in a wide range of domains including computer science, social science, biology, physics, and other sciences. The successful candidate will have the opportunity to develop their research skills in all aspects from conceptualization to publication and presentation. HCDE offers a vibrant multidisciplinary research environment with links to multiple departments within UW and research labs and companies in the Seattle area and around the world. NOTE: This is a full-time, one-year postdoctoral appointment with the possibility of extension to an additional year or two, depending on performance and availability of funding. Start date is September 15, 2013. FOR FURTHER INFORMATION OR TO APPLY, please contact Cecilia Aragon at aragon(a)uw.edu. To apply: email a cover letter, curriculum vitae, and a statement of research interests; also arrange for three letters of recommendation to be sent to the same email address. The University of Washington is an affirmative action, equal opportunity employer. -- Cecilia R.
