A device ( 1 ) for measuring the relative orientation according to at least one degree of freedom for two objects, including a constraint generator ( 10 ) suitable for causing a goniometric sensor ( 40 ) to move in a plane, having the function of measuring the variation of relative orientation of the two objects in this plane. The goniometric sensor ( 40 ) is arranged in a housing ( 41 ) that crosses longitudinally the constraint generator ( 10 ), which has high flexional stiffness in a first longitudinal plane (beta) and a low flexional stiffness in a second longitudinal plane (phi) orthogonal to the first (beta). The sensor measures rotations in a plane and the constraint generator induces a rotation in that plane. With the device ( 1 ) a data suit ( 50 ) can be made for measuring the movement of limbs of an individual. For example, arranging three devices ( 10 a, 10 b, 10 c) in series, but capable of measuring angles in orthogonal planes, the rotation can be measured of the arm ( 76 ) with respect to a shoulder ( 75 ) of an individual. |
