Abstract
A method for automatic recognition of a predetermined move of a user includes the construction of several characteristic physical quantities of the move of the user from acquired measurements performed by a tri-axial accelerometer only within a time interval [td; ti], where the instant ti is an instant, later than the instant td, at which the measured acceleration of a fist of the user in a direction Xm changes sign and becomes negative, the direction Xm being the direction parallel to a forearm of the user, directed from the elbow of the user to the fist of the user, then the classification of the move of the user in a predefined move category, chosen from among several possible predefined categories of moves, from these constructed characteristic physical quantities.
