Claim 0:
1. 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 a motion sickness-causing section based on a section in which a size of the motion detection data is not changed while a size of the motion control data is changed; and
operation (e) includes adjusting the motion control data to continuously change the size of the motion detection data in the motion sickness-causing section and generating the adjusted motion control data as the final motion control data.
