Effect of Inter-Stream Synchronization Errors in Haptic Media,Sound and Video Communications

Abstract

We investigated the effect of inter-stream synchronization errors in haptic media, sound and video communications on output quality by using a haptic media,sound and video transfer system.The system transmits a sense of force,and generated sound and video while a human subject uses haptic interface devices to touch a real object.Using subjective assessment,we demonstrated that the media output quality is highest when video output is observed slightly earlier than haptic media is felt and sound is heard.
