SYNTHESIS LECTURES ON VISUALIZATION SEMANTIC ...

This book discusses semantic interaction  a user interaction methodology for visual analytic
applications that more closely couples the visual reasoning processes of people with the
computation. This methodology affords user interaction on visual data representations that are
native to the domain of the data. User interaction in visual analytics systems is critical to
enabling visual data exploration. Interaction transforms people from mere viewers to active
participants in the process of analyzing and understanding data. This discourse between people
and data enables people to understand aspects of their data  such as structure  patterns 
trends  outliers  and other properties that ultimately result in insight. Through interacting
with visualizations  users engage in sensemaking  a process of developing and understanding
relationships within datasets through foraging and synthesis. The book provides a description
of the principles of semantic interaction  providing design guidelines for the integration of
semantic interaction into visual analytics  examples of existing technologies that leverage
semantic interaction  and a discussion of how to evaluate these technologies. Semantic
interaction has the potential to increase the effectiveness of visual analytic technologies and
opens possibilities for a fundamentally new design space for user interaction in visual
analytics systems.
