Abstract
The present work is a review of the PhD thesis defended by Egon L. van den Broek on September 16, 2011 at the department of Human Media Interaction, Faculty of Electrical Engineering, Mathematics, and Computer Science, University of Twente, Enschede, The Netherlands. I was a member of the PhD dissertation Committee. I was overwhelmed by the quality and the amount of work he did. The thesis is a great contribution to our understanding and harnessing the principles underlying affective multimodal communication and to the development of future real-world technologies for affective signal processing.
