Towards an Overall QoE Model for 360-Degree Video

Abstract

Although 360-degree video is becoming more and more popular on the Internet, understanding of Quality of Experience (QoE) of 360-degree video is still limited. In this paper, we aim to investigate for the first time the impacts of two QoE aspects, namely perceptual quality and presence, on the overall QoE of 360-degree video. By using a subjective dataset, statistical analysis shows that the overall QoE is significantly affected by the perceptual quality and presence. In addition, we make the first attempt to model the overall QoE of 360-degree video taking into account the impacts of the QoE aspects. In particular, two approaches are investigated to predict the overall QoE. The result shows that one of the approaches is applicable to predict the overall QoE of 360-degree video over different videos and rendering device sets.
