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

Abstract

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.
