April 5, 2008 - Florence, Italy WORKSHOP WEBSITE http://www.dis.uniroma1.it/~beliv08/ DESCRIPTION The purpose of information visualization is to provide users with accurate visual representations of data and natural interaction tools to support discovery and sense making. These activities are often exploratory in nature and can take place over days, weeks or months and rarely follow a predefined or linear workflow. While the overall use of information visualizations is accelerating, the growth of techniques for the evaluation of these systems has been slow. To understand these complex behaviors, 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 appear insufficient to quantify the quality of an information visualization system; thus the name of the workshop: “beyond time and errors ”. BELIV’08 aims at gathering researchers in the field to continue the exploration of novel evaluation methods, and to structure the knowledge on evaluation in information visualization around a schema, where researchers can easily identify unsolved problems and research gaps. DATES Deadline for submissions: October 3, 2007 Notification of acceptance: November 28, 2007 Camera ready papers due: TBA Workshop: April 5, 2008 HOW TO PARTICIPATE To participate to the workshop it is necessary to have a paper accepted and be registered both to the workshop and the main CHI conference. Paper Types We accept either research papers (4 to 8 pages) or position papers (1-2 pages) describing participant\'s relevant experiences and ideas that can contribute to the discussion. Papers will be peer-reviewed by a program committee and selected according to their quality and relevance. Accepted *research* papers will be refined after the workshop and be published in the ****ACM digital library****. Submission To submit a paper send an email to: beliv08@dis.uniroma1.it by October 3, 2008. Format All the submissions should be formatted in the ACM style. Suitable templates, in LaTeX and Word, can be downloaded from: http:// www.acm.org/sigs/pubs/proceed/template.html. Submission should be either in PDF (preferred) or Word formats.
