The present invention provides an apparatus for analyzing human motion including a bio-sensor configured to transmit a bio-signal by being attached to a body part a receiver configured to receive the bio-signal and a controller configured to determine position and velocity of the bio-sensor based on the bio-signal and estimate position and velocity of the joint adjacent to the body part based on the position and velocity of the bio-sensor. Accordingly, the present invention can reduce restrictions in movements by using a wireless bio-signal without having any problem in being hidden.
