Abstract: Methods and apparatus provide for acquiring, from a plurality of sensors attached to a plurality of body parts of a target person, at least information regarding movement acceleration and posture angular velocity of each of body parts to which the sensors are attached, and estimating, on the basis of the acquired information regarding the movement acceleration and posture angular velocity, the movement velocity in a predetermined coordinate system of each of the body parts to which the sensors are attached. Subsequently, on the basis of the information regarding the estimated movement velocity of each of the body parts, the methods and apparatus provide for estimating the positions of predetermined body parts of the target person.
