Abstract: Provided are an apparatus and a method of effectively creating real-time movements of a three dimensional virtual character by use of a small number of sensors. More specifically, the motion capture method, which maps movements of a human body into a skeleton model to generate movements of a three-dimensional (3D) virtual character, includes measuring a distance between a portion of a human body to which a measurement sensor is positioned and a reference position and rotation angles of the portion, and estimating relative rotation angles and position coordinates of each portion of the human body by use of the measured distance and rotation angles.
