1. A device for interpreting gestures of a user comprising:
- at least one input module for measurements comprising at least one motion capture assembly on at least a first and a second axis,a module for processing signals sampled at an output of the input module, andan output module capable of playing back a musical meaning of said gestures,the signal processing module comprising a submodule for analyzing and interpreting the gestures comprising a filtering function, a function for detecting the gestures by comparison of a variation between at least two successive values in the sample of at least one of the signals originating from at least the first axis of the set of sensors with at least a first selected threshold value and a function for confirming the detection of a gesture,wherein said function for confirming the detection of a gesture is capable of comparing at least one of the signals originating from at least the second axis of the set of sensors with at least a second selected threshold value.

Abstract
Musical rendition is provided through the use of microsensors, in particular of accelerometers and magnetometers or rate gyros, and through an appropriate processing of the signals from the microsensors. In particular, the processing uses a merging of the data output from the microsensors to eliminate false alarms in the form of movements of the user unrelated to the music. The velocity of the musical strikes is also measured. Embodiments make it possible to control the running of mp3 or wav type music files to be played back.
