ELECTRONIC DEVICE, MONITORING AND FEEDBACK SYSTEM ON THORACOABDOMINAL MOTION AND METHOD THEREOF

摘要

An electronic device, a monitoring and feedback system on thoracoabdominal motion (TAM) and a method thereof are provided, where the method includes the following steps. TAM signals of a user in a natural state are measured. Next, the TAM signals are decomposed so as to extract main components thereof. Energy of the main component and the non-noise components of the abdominal motion signal are calculated to obtain the abdominal muscle contraction. Instantaneous phases of the main component of TAM signals are calculated to obtain the instantaneous coordination of TAM and the self-ability for adjusting TAM. A TAM mode of the user is evaluated in the natural state according to the abdominal muscle contraction, the instantaneous TAM coordination, and the self-ability for adjusting TAM. The user is further instructed to adjust the TAM mode to a suitable state according to a target environment mode.

1. A monitoring and feedback method on thoracoabdominal motion (TAM), adapted to a system having a signal sensing device and an electronic device, comprising:
measuring and extracting a thorax motion signal and an abdominal motion signal of a user in a natural state within a predetermined time period; decomposing the thorax motion signal and the abdominal motion signal so as to extract a main component of the thorax motion signal and a main component of the abdominal motion signal respectively; calculating main component energy and non-noise component energy of the abdominal motion signal and obtaining abdominal muscle contraction accordingly; calculating an instantaneous phase of the main component of the thorax motion signal and an instantaneous phase of the main component of the abdominal motion signal so as to obtain instantaneous coordination of the TAM and a self-ability for adjusting the TAM; evaluating a TAM mode of the user in the natural state according to the abdominal muscle contraction, the instantaneous TAM coordination, and the self-ability for adjusting the TAM; and providing a plurality of other environment modes for selection, and instructing the user to adjust the TAM mode to a suitable state according to a target environment mode selected from the other environment modes.
