Abstract
(EN)
A motion capture device according to an embodiment of the present invention comprises: a reception unit for receiving motion measurement data measured by a motion measurement sensor attached to each part of the body of a subject to be measured; a center-of-gravity calculation unit for configuring a human body motion for each frame, for the subject to be measured, on the basis of the motion measurement data, and calculating the center of gravity of the human body motion for the each frame; a jump determination unit for determining whether a jump motion has occurred, on the basis of the magnitude of an acceleration signal included in the motion measurement data; and a motion implementing unit for, when it is determined that the jump motion has occurred, determining a jump path of the human body motion on the basis of the center of gravity of the human body motion and implementing a motion of a virtual character by using the determined jump path.
