Method for analyzing the movements of a person, and device for implementing same

A method for analyzing at least one sequence of movements performed by a person having a set of characteristic points, each movement comprising a succession of elementary actions, said method comprising:

• a step of observing the sequence of movements using at least one acquisition system configured for supplying raw data relating to positions of at least some characteristic points of the set of characteristic points,
• a step of segmenting the sequence of movements into time units, each associated with an instant,
• a step of determining, for each instant, the positions of at least some characteristic points of the set of characteristic points, using the acquisition system,
• a step of assigning, at each instant, at least one position code for at least some characteristic points of the set of characteristic points, as a function, for each of them, of the determined position, to form a combination of position codes at each instant;
• a step of assigning at least one elementary action code for each given instant corresponding to the combination of position codes at the given instant;
• and
• a step of syntactically verifying at least one of the elementary action codes or the position codes based on at least one structured language which has at least one grammatical rule and at least one lexicon, in order to refine the raw data relating to the positions of the characteristic points.
