Claim One:
1. A method for determining, by a sensor assembly including at least one orientation sensor, values of parameters representing a movement involving at least two limbs of an entity represented in a form of an articulated chain in which each limb is represented by at least one segment and the at least two limbs are connected together by an articulation, the sensor assembly including the at least one orientation sensor being fixed to the entity and configured to measure a parameter representing an orientation of a first segment of the articulated chain, the method comprising: receiving an orientation value measured and supplied by the orientation sensor; estimating a value of at least one first parameter representing a movement of the first segment by processing of the supplied orientation value; and estimating a value of at least one other parameter by executing a time-change model on the basis of a predetermined movement model of the articulated chain, the time-change model including at least one relationship of time dependency between the at least one first parameter and the at least one other parameter representing a movement of another segment of the articulated chain.
