Study of Relationship between QoS and QoE for Web Services with Parallax Effect

This paper studies the relationship between QoS and QoE for Web services which utilize the parallax effect by experiment. In the experiment, the authors consider 8 actual Japanese Web services and assess QoE and QoS of them; they analize the results by the principal component analysis and the linear multiple regression analysis. The experimental results show that, some QoE parameters cannot be affected QoS degradation by using the parallax effect. Therefore, even if QoS is deteriorated, the parallax effect can keep some aspects of QoE high. From these results, the authors suggest that if we make Web pages with the parallax effect properly, they can become tolerant to QoS degradation.
