Abstract
A method determining values of parameters representing a movement of an entity represented by an articulated chain, by a sensor assembly including at least one sensor for a parameter representing an orientation of a first segment of the articulated chain, the method including: reception of an orientation value measured and supplied by the orientation sensor; estimation of a value of at least one first parameter representing a movement of the first segment by processing the orientation value; and, based on a predetermined movement model of the articulated chain, as a time change model, including at least one relationship of time dependency between the at least one first parameter and at least one other parameter representing a movement of another segment of the articulated chain: estimation of a value of the at least one other parameter by application of the time change model to the estimated value of the at least one first parameter.

11. A method for determining values of parameters representing a movement by a sensor assembly, the movement involving at least two limbs of an entity represented in a form of an articulated chain in which each limb is itself represented by at least one segment and the at least two limbs are connected together by an articulation, the sensor assembly being fixed to the entity and including at least one orientation sensor for a parameter representing an orientation of a first segment of the articulated chain, the method comprising:
-
reception of an orientation value measured and supplied by the orientation sensor; estimation of a value of at least one first parameter representing a movement of the first segment by processing of the orientation value supplied; and executed on the basis of a predetermined movement model of the articulated chain, as a time-change model, including at least one relationship of time dependency between the at least one first parameter and at least one other parameter representing a movement of another segment of the articulated chain; estimation of a value of the at least one other parameter by application of the time-change model to the estimated value of the at least one first parameter. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
