Combination of physiological and subjective measures to assess quality of experience for audiovisual technologies

Résumé

The competitive context in which the number of new audiovisual services increases requires taking user preferences into account to maintain the best possible quality of experience. The aim of the experiment presented in this paper is to study how the standardized ITU subjective measures may be supplemented by physiological measurements. Subjective assessments (ITU-T P.920, P.911) and physiological measurements (BVP, temperature, skin conductance and eye tracking) are collected from 34 subjects viewing three different 2D audiovisual contents. For each content, three different quality conditions are considered: reference one and two audio and/or video degraded ones (temporal asynchrony or bitrates variations). The results didn’t show an impact of the quality variation on the physiological measures but an effect was observed, as expected, on subjective data. However, results do not permit to conclude a lack of degradations’ effect on measures of physiological.
