摘要： A method comprising: digitally processing orientation measurements provided by each of first and second inertial measurement units, the first and second units being arranged on first and second body members of a person, respectively, according to a predetermined unit arrangement, and the first and second body members being connected by a joint; the measurements are digitally processed such that the computing device at least: computes a length vector of a segment of the first body member based on a first orientation measurement of the first unit; defines a joint axis plane of the joint based on a second orientation measurement of the second unit; and computes a heading rotation value for making the first orientation measurement to be contained within the joint axis plane defined; and the method further comprising digitally modifying the first orientation measurement or the second orientation measurement by applying a rotation at least based on the heading rotation value computed. Also, a motion tracking system and a computer program product.

摘要： A method for adjusting operation of a motion tracking system at least comprising first and second sensors and a computing device, each of the first and second sensors at least comprising a gyroscope, the method comprising: arranging the first sensor on an upper arm of a person, and the second sensor on a chest of the person; measuring orientations each of the first and second sensors while the person performs a predetermined movement, the predetermined movement comprising the person moving a torso thereof with respect to a hip of the person while keeping the upper arm parallel to the torso and not rotating the upper arm; digitally processing, the computing device, the orientations measured so as to digitally compute an orientation difference between the orientations measured by the first sensor and the orientations measured by the second sensor; and adjusting, the computing device, the operation of the motion tracking system based on the orientation difference computed.

摘要： Methods and systems for tracking movement of a person, including a method comprising: arranging a plurality of sensors of a motion tracking system on a body of the person; tracking movement of the person with the plurality of sensors at least while the person performs a movement; digitally estimating, with a computing device, a position of either the first joint or the sensor on the second body member, wherein the position of the first joint is estimated using measurements of the first sensor and the position of the sensor is estimated using measurements of both the first sensor and the sensor arranged on the second body member, and wherein the position is estimated while movement of the person is tracked; digitally computing, with the computing device, an acceleration of the estimated position while movement of the person is tracked; digitally computing, with the computing device, a first comparison between the computed acceleration of the estimated position and acceleration measurements of the sensor arranged on the second body member; and digitally determining, with the computing device, the movement performed by the person based on the first comparison.
