Claim 6:
7. A control method of a motion sickness reduction apparatus for a virtual reality (VR) motion platform, the method comprising:
(a) receiving content motion data included in VR content;
(b) transmitting motion control data corresponding to the content motion data received in operation (a) to a motion device and controlling motion of the motion device;
(c) receiving motion detection data corresponding to a motion state of the motion device from a predetermined sensing device;
(d) selecting a motion sickness-causing section using a difference between the motion control data and the motion detection data;
(e) generating final motion control data for minimizing a degree of motion sickness in the motion sickness-causing section selected in operation (d) during a preset content reproduction section according to a preset algorithm and storing the final motion control data, and
(f) transmitting the final motion control data stored in operation (e) to the motion device and controlling the motion of the motion device when three-dimensional (3D) VR content is reproduced and processed, wherein:
operation (d) includes selecting the motion sickness-causing section based on a section in which a difference between change in the motion control data and change in the motion detection data is equal to or less than a preset value; and
operation (e) includes adjusting the motion control data to increase the change in the motion detection data in the motion sickness-causing section compared with a preset value and generating the adjusted motion control data as the final motion control data.
