QoE assessment in haptic media, sound and video transmission: Influences of network latency

In this paper, we investigate the influences of the difference in network latency among haptic media, sound and video on the quality of experience (QoE) for a haptic media, sound and video transfer system. In the case where network delay jitter exists, we subjectively assess the operability of haptic interface device, sound output quality, video output quality, inter-stream synchronization quality, and comprehensive quality as QoE. We also evaluate the application-level quality of service (QoS), and we demonstrate that it is possible to estimate QoE parameters from QoS parameters with high accuracy.
