Assessing the effectiveness of visual analytics technology is challenging because VA tools often combine several disparate components, both low and high level, integrated in complex interactive systems used by analysts. These components include analytical reasoning, visual representations, computer human interactions, data representations and algorithms, tools for collaboration and especially for communicating the results of their usage. Users' activities can be exploratory and can take place over days, weeks or months. Users may not follow a predefined or even linear work flow. Users may work alone or in groups. To understand these complex behaviors, evaluation efforts can be targeted at the component level, the system level, and the work environment level, and require realistic data and tasks. Traditional evaluation metrics such as task time completion, number of errors, or recall and precision are insufficient to quantify the utility of visual analytics tools, and new research is needed to improve our visual analytics evaluation methodology. We invite submissions in all areas related to the Evaluation of Visual Analytics. Topics include, but are not limited to * Evaluation metrics and tools * Insight characterization and measures * Benchmark task and data set development * Methodology of longitudinal case studies * Characterization of the challenges of VA evaluation * Survey of existing VA evaluation methodologies * Lessons learned from specific evaluation activities * Automation of evaluation * Synthetic data set generation and usage Articles should be no more than 10 magazine pages, where a page is 750 words and an image counts as 200 words.

APGV 08 - call for papers
by Bernhard Riecke 04 Mar '08

04 Mar '08

--------------------------------------------------------------------- APGV 08: FIFTH SYMPOSIUM ON APPLIED PERCEPTION IN GRAPHICS AND VISUALIZATION Co-located with ACM Siggraph in Los Angeles, USA 9th - 10th August, 2008 http://www.apgv.org CALL FOR PARTICIPATION --------------------------------------------------------------------- Research in computer graphics and visualization has great potential to benefit from, and contribute to, research in perception. Since 2004, this symposium has brought together researchers from the fields of perception, graphics, and visualization, to facilitate a wider exchange of ideas. Submissions are invited in the broad range of areas at the intersection of computer graphics, visualization, and perception to fulfill two goals of this multidisciplinary community. Goal 1. Use insights from perception to advance the design of methods for visual, auditory and haptic representation. Specific examples include, but are not limited to: * applications of insights from perception to the development of algorithms for more efficient, effective or realistic modeling, rendering and/or animation * applications of perception in the design and evaluation of methods for more effective representation and communication of data * computational aesthetics, stylization and perceptual aspects of non-photorealistic rendering * perceptual issues arising due to fusion of digital imaging, computer vision, and computer graphics techniques * perception-inspired interfaces for immersive activities in virtual worlds Goal 2. Advance and facilitate novel basic perception and cognition research that uses and is relevant to applications in computer graphics and visualization. Here specific examples include, but are not limited to: * perception and visuomotor control in computer games, virtual and augmented environments * fundamental contributions in spatial and temporal vision * integration of empirical perception research with computational models * color vision and color appearance modeling * the influence of attention and eye movements on visual perception and visual memory * statistical learning and perception of natural scenes * perception of shapes, surfaces and materials * visual illusions and perceptual organization having potential to enhance image depiction Proceedings, which will include the poster abstracts, will be published by ACM SIGGRAPH. Best papers from the symposium will be invited to be extended for a special issue of the ACM Transactions on Applied Perception. http://www.acm.org/tap/ By co-locating APGV 08 with the thirty-fifth annual SIGGRAPH Conference (SIGGRAPH 08), we aim to further promote communication between the core perception and the core computer graphics communities, and also bring APGV back to the United States.

CFP: Geospatial Visual Analytics @ GIScience 2008
by Andrienko 03 Mar '08

03 Mar '08

Geospatial Visual Analytics Workshop at the GIScince 2008 Conference (Park City, Utah, USA, 23-26 September 2008) and Special Issue of the CaGIS journal (provisional issue Vol.36 No.3, July 2009) The workshop is a follow-up to the successful workshop on “Visualization, Analytics and Spatial Decision Support” at the GIScience’2006 conference. The previous workshop attracted about 70 participants. Selected workshop papers, including the "Setting the research agenda" paper, were published as a special issue of IJGIS, v.21(8), 2007. The workshop supported by the Commission on GeoVisualization (http://geoanalytics.net/ica) of the International Cartographic Association aims at bringing together researchers from relevant fields to address research issues of geospatial visual analytics in the multidisciplinary context of GI Science. A big part of data that the modern society deals with has both spatial and temporal characteristics. Visualisation of spatial and temporal data traditionally belongs to the research area known as geographic visualisation, or geovisualisation. Geovisual Analytics (short for Geospatial Visual Analytics) extends geovisualisation research by enhancing purely visual and interactive methods with new possibilities provided by computational techniques such as data mining, statistics, and optimisation. Potential enhancements come also from developing methods to support analytical reasoning, argumentation, knowledge building, and knowledge communication. The frontier research problems in Geovisual Analytics involve the scalability of tools and their usability. The goal of the workshop is to present the most advanced methods and applications of geovisual analytics, discuss problems and possible approaches to solving them, and define appropriate directions for further research. Major scientific topics to be addressed: - scalability - how to make visualisation suitable for huge data sets (e.g. with the help of database technologies and data mining); - usability – how to fit the tools to the needs, abilities and conditions of different categories of users (for example, domain experts vs. decision makers); - effectiveness - how to ensure the effectiveness of visual analytics tools and how to test and prove it; - innovative visually driven methods of data analysis addressing the problems of scalability, usability, and effectiveness. Challenging applications of geovisual analytics: - decision support: * generation, evaluation and comparison of alternatives, * accounting for uncertainty of decision recommendations, * explanation, justification, and communication of results; - education: enhancing learning and knowledge transfer; - scientific research: acquiring new knowledge; - collaboration: supporting communication, cooperative problem solving and knowledge construction. Authors are invited to submit original research contributions or application reports in English. The authors are requested to stress the multidisciplinary character of their approaches and their relevance to the theme of the workshop. We encourage submissions presenting early stages of cutting-edge research and development, as well as submissions from PhD students. Organizers and Guest Editors: Gennady and Natalia Andrienko, Piotr Jankowski, Menno-Jan Kraak ICA Commission on GeoVisualization, http://geoanalytics.net/ica Submission and selection procedure: - March 3, 2008 - CFP announced - June 1, 2008 - Authors should submit extended abstracts.
