A causality and inter-destination synchronization control scheme for haptic media in distributed virtual environments

摘要

This report proposes a causality and inter-destination (or group) synchronization control scheme for haptic media in distributed virtual environments where multiple users manipulate objects collaboratively in a 3-D virtual space by using force feedback devices. For inter-destination synchronization control, which adjusts the output timing among multiple destinations we enhance the synchronization maestro scheme, which the authors previously proposed. We also perform causality control in order to keep the temporal order of manipulation events. We demonstrate the effectiveness of the proposed scheme by experiment.
