Abstract:
1. Method of obtaining a signature (S) of a gesture (G) produced in free space, by deriving at least one time-evolving signal ( 14 ) representative of muscular activity involved in producing the gesture and determining at least one value of a parameter (Psfi) yielded by that signal, comprising the steps of: time dividing the time-evolving signal ( for at least one sub-frame (SFi): the resultant vector forming the signature (S) of said gesture (G); and identifying an analyzed gesture among a set of previously learnt gestures acquired in a learning mode, each learnt gesture being expressed as a signature vector, wherein a decision on the identification of a gesture under identification is produced while that gesture is still giving rise to an active time-evolving signal (
