Summary:
This research investigated the relationship between QoE (Quality of Experience) of audiovisual content and heart-rate variability using wearable heart-rate sensor. As the analysis method of heart-rate variability, the LF ratio obtained by frequency analysis of RRI (R-R Interval), the distance from the origin to the center of the ellipse by which the Lorenz plot is approximated and the area of the ellipse were used. First, heart-rate variability was measured for audiovisual content that was not affected by quality degradation due to video stop. As a result, the stress index calculated from the heart-rate variability when viewing the audiovisual content that subject would not want to see indicated that the subject tended to feel stress. Next, heart-rate variability was measured for audiovisual content that was affected by quality degradation due to video stop. There was a partial relationship between QoE of audiovisual content with quality deterioration and heart-rate variability.
