Abstract: The present invention relates to a motion control system and method using detection of motions in a video, and the motion control system includes: a video processing device for decoding encoded video to extract motion vectors and residual values of effective macroblocks, producing motion codes using the extracted motion vectors and residual values of the effective macroblocks, reproducing the decoded video, and transmitting the produced motion codes and the time codes corresponding to the video being reproduced to a motion control device; and the motion control device for receiving the time codes and motion codes from the video processing device and controlling motions of actuators according to the motion codes if the time values of the time codes and motion codes correspond to each other.

Abstract: Disclosed are a system and method for playing back virtual reality 4D content. The system for playing back virtual reality 4D content, includes an image server configured to provide content or an effect control signal, a head-mounted display (HMD) device configured to display the content, and a 4D apparatus configured to generate an effect synchronized with the content in response to the effect control signal.

Abstract: The present invention relates to a motion chair included in a 4D theater and a motion chair control system for controlling a plurality of the motion chairs. More specifically, the present invention relates to a motion chair, including a control unit configured to receive control data from an operating server and selectively control some or all of effect device control units, the effect device control units configured to correspond to one or more effect devices and to independently control corresponding effect devices under the control of the control unit, and the effect devices for implementing special effects, and a system for controlling the motion chairs.
