Speaker: Dr. Petra Isenberg (INRIA, AVIZ research group)

The need for evaluating visualization research has been widely recognized. We have come a long way in establishing a more formal way for validating visualization research. Yet, our current evaluation practices in visualization are not without criticism. There even seems to be a common perception in the community that we have to some extent overemphasized evaluation culminating in the expression of the "tyranny of the user study".  In this presentation I will shed some light on the current state of evaluation practices, discuss some (potential) problems with our current approaches and how to deal with them and highlight issues that the community will likely encounter in the coming years.
