Title: Interactive Visualization – A Key Discipline for Big Data Analysis

Presenter：Thomas Ertl

Visualization Research Center, University of Stuttgart, Germany

Abstract:

Big Data has become the general term relating to the benefits and threats
which result from the huge amount of data collected in all parts of society.
While data acquisition, storage and access are relevant technical aspects,
the analysis of the collected data turns out to be at the core of the Big
Data challenge. Automatic data mining and information retrieval techniques
have made much progress but many application scenarios remain in which the
human in the loop plays an essential role. Consequently interactive
visualization techniques have become a key discipline of Big Data analysis
and the field is reaching out to many new application domains. This talk
will give examples from current visualization research projects at the
University of Stuttgart demonstrating the thematic breadth of application
scenarios and the technical depth of the employed methods. We will cover
advances in scientific visualization of fields and particles, visual
analytics of document collections and movement patterns as well as cognitive
aspects.   

Biography:

Thomas Ertl received a MSc in computer science from the University of
Colorado at Boulder and a PhD in theoretical astrophysics from the
University of Tübingen. Since 1999 he is a full professor of computer
science at the University of Stuttgart now leading the Visualization and
Interactive Systems Institute (VIS) and the Visualization Research Center of
the University of Stuttgart (VISUS). His research interests include
visualization, computer graphics and human computer interaction in general
with a focus on volume rendering, flow and particle visualization, parallel
and hardware accelerated graphics, large datasets and interactive steering,
visual analytics of text collections and social media, user interfaces and
navigation systems for the blind.  Dr. Ertl is coauthor of more than 400
scientific publications and he served on numerous program committees and as
a papers co-chair for most conferences in the field. From 2007-2010 Dr. Ertl
was Editor-in-Chief of the IEEE Transactions on Visualization and Graphics
(TVCG) and in 2011/2012 he served as Chairman of the Eurographics
Association. He received the Outstanding Technical Contribution Award of the
Eurographics Association and the Technical Achievement Award of the IEEE
Visualization and Graphics Technical Committee in 2006. In 2007 he was
elected as a Member of the Heidelberg Academy of Sciences and Humanities. He
received Honorary Doctorates from the Vienna University of Technology in
2011 and from the University of Magdeburg in 2014.
