Abstract
This paper deals with inter-destination (or group) synchronization control for haptic media in the case where two groups each of which consists of two players play a networked real-time game in which the two players in each group do collaborative work. The synchronization maestro scheme, which the authors previously proposed, is enhanced and applied to the control. We investigate the influences of how to determine the reference output timing on the fairness and the efficiency of the work. By experiment, we also demonstrate the effectiveness of a proposed method which employs two different reference output timings. The method adjusts the earlier output timing in a group to that in the other group and also adjusts the remaining two output timings.
