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,...
In this paper, we deal with a remote haptic instruction system in which a teacher teaches a student how to write characters by using haptic interface devices. We have two cases in the system. In one case, a pen is attached to only the student terminal, and video is transmitted from the student terminal to the teacher terminal. In the other case, a pen is attached to each of the two terminals, and...
This paper proposes group (or inter-destination) synchronization control considering difference of conversation roles in multipoint communications where users have a conversation with each other by using voice and video. By subjective assessment, the paper also investigates the effects of the proposed control for networked rock-paper-scissors. Assessment results show that the control can maintain...
By subjective assessment, this paper investigates the effects of group (or inter-destination) synchronization control in networked virtual environments where users have a conversation with each other by using avatars constructed by computer graphics (CG) and live voices. Assessment results show that the fairness among the users can be maintained high under the group synchronization control in networked...
