METHOD AND SYSTEM FOR QUANTIFYING AN INTENTION OF MOVEMENT OF A USER

摘要

A method for quantifying an intention of movement of a user, the method comprising: extracting (61) a mechanomyogram (MMG) signal in response to surface vibration of a muscle of the user; and averaging (62) the MMG signal by calculating the MMG root mean squared (RMS) amplitude (63) or frequency variance (64) in a predetermined time window; where an increasing RMS amplitude of the MMG signal corresponds to increasing muscle voluntary contraction or a decreasing frequency variance of the MMG signal corresponds to increasing muscle voluntary contraction.
