QoE assessment in olfactory and haptic media transmission: Influence of inter-stream synchronization error

In this paper, we deal with harvesting fruit in a 3-D virtual space for an olfactory and haptic media display system. Making use of the system, a user can pick fruit from a tree in the 3-D virtual space and perceive the smell of picked fruit by using an olfactory display (SyP@D2) and the reaction force when picking fruit by using a haptic interface device (PHANToM Omni). In the case where there exists inter-stream synchronization error between olfactory and haptic media, we assess the inter-stream synchronization quality as the quality of experience (QoE).
