Tobias Hossfeld, Poul E. Heegaard, Martin Varela, Sebastian, M\"oller

TL;DR
This paper provides a formal mathematical definition of Quality of Experience (QoE) metrics, extending beyond traditional MOS, with accompanying Matlab scripts for practical computation.
Contribution
It introduces a rigorous formal framework for QoE metrics and links them to MOS, enhancing the precision and applicability of QoE assessment methods.
Findings
Formal definitions of QoE metrics provided
Matlab scripts for metric computation available
Enhanced understanding of QoE beyond MOS
Abstract
This technical report formally defines the QoE metrics which are introduced and discussed in the article "QoE Beyond the MOS: An In-Depth Look at QoE via Better Metrics and their Relation to MOS" by Tobias Ho{\ss}feld, Poul E. Heegaard, Martin Varela, Sebastian M\"oller, accepted for publication in the Springer journal "Quality and User Experience". Matlab scripts for computing the QoE metrics for given data sets are available in GitHub.
