PROBLEM TO BE SOLVED: To provide a human posture and motion discrimination apparatus capable of precisely discriminating that a person is in either state of standing, sitting, being recumbent, running, walking, ascending the stairs, descending the stairs, or tumbling using a triaxial acceleration sensor worn on a human body. SOLUTION: This human posture and motion discrimination apparatus for discriminating the posture and motion states of a person using an acceleration detecting means worn on the human body placing its front/rear in the X direction, its right/left in the Y direction and its vertical direction in the Z direction, is provided with: the acceleration detecting means detecting the X-directional acceleration, the Y-directional acceleration and the Z-directional acceleration which orthogonally cross one another; a means for calculating a Z-directional posture component from the detected Z-directional acceleration; a means for calculating a mean value of motor components of resultant composite accelerations of three-directional accelerations from the detected three-directional accelerations; and a first discrimination means discriminating that the person is in either state of the posture states or the motion states based on the calculated Z-directional posture component and the mean value of the motion components of the resultant composite accelerations of the tree-directional accelerations.
