This paper describes equipment that computes and displays biomechanical quantities, such as joint moments, joint forces, and the center of gravity, together with symmetric motions of subjects with respect to the sagittal plane. These biomechanical quantities are computed in real-time on the basis of inverse dynamics by measuring the marker positions using real-time image processing on body movements captured by a CCD camera. These biomechanical quantities are displayed in real-time on an LCD projector screen and accordingly the subject can recognize the qualities and quantities of the motion as he or she is performing the motion. The real-time motion analyzer was used to analyze bowing, bending and stretching, and sit-to-stand motions, and it was found to be advantageous for coaching and self-education to learn optimal motions based on body mechanics.
