Technologyy of synchro record and simulation online of motion includes two contents. The one is that technologyy of synchro record of motion. It means that motion signals and audio-video signals on the spot are collected and recorded synchronously through the motion recorded device, while goal object moves; and then the recorded motion signals and audio-video signals are reappeared by the motion reappeared device. The other means the technology of synchro simulation online of motion. It means that the the motion signals and audio-video signals recorded on the spot are transferred to the far-ended controlled computer through wireless network; synchronously the recorded motion signals and audio-video signals are reappeared based on motion simulator system.
