In this paper we discuss recent extensions to the RealEYES framework for usability studies which allow to integrate affect sensing devices (namely the EREC system) and to process sensor data with machine learning algorithms. The extensions enable the usability researcher to automatically find critical incidents in usability studies. We also present results of a study showing that integrating affect sensors in the usability test framework opens new perspectives in usability studies.
