This paper proposes a group (or inter-destination) synchronization scheme with prediction for haptic media in
a remote drawing system. The scheme aims to improve the group synchronization control, which adjusts the
output timing among multiple destinations, to keep the interactivity high. It outputs the position information by
predicting the future position later than received position information by a fixed amount of time. It also advances
the output time of position information at the local terminal by the same amount of time. By experiment, we
demonstrate the effectiveness of the scheme.
This paper deals with a remote control system which controls a haptic interface device with another remote haptic interface device. Applications of the system include a remote drawing instruction system, a remote calligraphy system and a remote medical operation system. This paper examines the influence of network latency on the output quality of haptic media by subjective assessment in the remote drawing instruction system. As a result, we show that the instructor has smaller Mean Opinion Score (MOS) values than the learner, and the MOS value can be estimated with high accuracy from the summation of the network latency from an instructor's terminal to a learner's terminal and that in the opposite direction.
