Evaluating QoE by means of traditional and alternative subjective measures: an exploratory 'living room lab' study on IPTV

In this paper, we explore the use of a set of potential ‘alternative’, emotional state and engagement-related measures of QoE and investigate how they relate to traditional QoE measures. To this end, we present results from a living room lab study (N=28) in which the impact of slicing errors on QoE was investigated. Our findings indicate significant differences in QoE between the three used error profiles, both when considering the traditional and alternative measures. Furthermore, we found that the link between the traditional and alternative measures is rather weak, indicating that the former may need to be reconsidered and extended with alternative measures, which allow to measure QoE in terms of ‘delight’ or ‘annoyance’.
