Title: | Method and system for quantifying an intention of movement of a user | Authors: | Lei, KF Leung, WWF |
Issue Date: | 19-Feb-2013 | Source: | US Patent 8,376,968 B2. Washington, DC: US Patent and Trademark Office, 2013. | Abstract: | A method for quantifying an intention of movement of a user, the method comprising: extracting a mechanomyogram (MMG) signal in response to surface vibration of a muscle of the user; and averaging the MMG signal by calculating the MMG root mean squared (RMS) amplitude or frequency variance 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. | Rights: | Assignee: The Hong Kong Polytechnic Univeristy. |
