QoE assessment of joint haptic drum performance: Effect of local lag control

This paper investigates the effect of local lag control on the synchronization quality of sound, interactivity, and comprehensive quality as QoE (Quality of Experience) in a networked haptic drum system. We handle joint performance in the system, where two users play a drum set in a 3D virtual space with the same rhythm at the same tempo. As a result, we illustrate that QoE depends on the network delay, and there exists the optimum value of local lag according to the network delay.
