A multidimensional QoE monitoring system for audiovisual and haptic interactive IP communications

This paper deals with audiovisual and haptic interactive IP communications and designs a multidimensional QoE monitoring system with the QoE estimation in real time. For the estimation, we carry out regression analysis between QoE and application-level QoS and obtain equations for the estimation. We measured the application-level QoS and made a subjective experiment by assessing QoE multidimensionally with the SD method. To monitor QoE, we derive estimates for three QoE metrics. We apply linear and non-linear regression analysis to the experimental results. As a result, we find that the obtained equations can estimate QoE with high accuracy. By using the equations, we have built the QoE monitoring system.
