Effect of QoS degradation on parallax effect in web services

This paper studies an effect of QoS degradation on the parallax effect for Web services by experiment. In the experiment, the authors consider 23 actual Web services and assess QoE of them. The experimental results show that, even if QoS is deteriorated, the parallax effect can be maintained for some services. Moreover, the authors study the characteristics of such the services and find common characteristics of them. From these results, the authors suggest that if we make Web pages with the parallax effect properly, they can become tolerant to QoS degradation.
