摘要: A system and method are described herein for detecting a user's transition between sitting standing postures. Transitions states reliably detected using an accelerometer attached to the user. By modeling error introduced by accelerometer, correcting this error, transitions detected. microprocessor coupled converts captured data approximate vertical acceleration. Vertical velocity, which includes is determined from The velocity corrected, corrected used determine displacement.
