As part of the colloquium of the Visualization and Data Analysis group at the University of Vienna, Prof. Tamara Munzner (University of British Columbia, Canada) talks about:
"A Duo of Visualization Design Studies”
When: 28. May 2014, at 15:00
Where: University of Vienna (Währinger Straße 29, 1090 Wien, HS3)
Abstract:
I will discuss the methodology of design studies, an increasingly popular form of problem-driven visualization research, and present two case studies from two very different application domains: automotive networks and genomics. RelEx supports automotive engineers who need to specify and optimize traffic patterns for in-car communication networks. The task and data abstractions that we derived support actively making changes to an overlay network, where logical communication specifications must be mapped to an underlying physical network. These abstractions are very different from the dominant use case in visual network analysis, namely identifying clusters and central nodes, that stems from the domain of social network analysis. Variant View supports scientists studying the genetic basis of disease; determining the impact of gene sequence variants is difficult because it requires reasoning about both the type and location of the variant across several levels of biological context.
The tool provides an information-dense visual encoding that provides maximal information at the overview level, in contrast to the extensive navigation required by currently-prevalent genome browsers
Biography:
Tamara Munzner is a professor at the University of British Columbia Department of Computer Science, and holds a PhD from Stanford. She has been active in visualization research since 1991 and has published over fifty papers and book chapters. Her research interests include the development, evaluation, and characterization of information visualization systems and techniques from both problem-driven and technique-driven perspectives. She has worked on problem-driven visualization projects in a broad range of application domains including genomics, evolutionary biology, geometric topology, computational linguistics, large-scale system administration, web log analysis, and journalism. Her technique-driven interests include graph drawing and dimensionality reduction.
She co-chaired EuroVis in 2010 and 2009, and InfoVis in 2004 and 2003. She currently serves as chair of the VisWeek Executive Committee and a member of the InfoVis Steering Committee. She was a founding member of the BioVis Steering Committee, and a Member At Large of the Executive Committee of the IEEE Visualization and Graphics Technical Committee (VGTC) from 2004 through 2009. She has consulted for or collaborated with many companies including Agilent, AT&T Labs, Google, Microsoft, Silicon Graphics, and several startups.
