Abstract:
A photoplethysmography (PPG) circuit obtains PPG signals at one or more wavelengths. The PPG signal is processed to identify motion artifacts. The motion artifacts are correlated with predetermined PPG signal patterns associated with a movement of a body part. The PPG signals may thus be used to detect movement of the body part. A user device may be controlled in response to the detected movement of the body part.

Claim (Index 1):
A biosensor, comprising:\n a sensor configured for positioning over an area of tissue of the user and configured to obtain a photoplethysmography (PPG) signal, wherein the PPG signal includes a spectral response around a first wavelength of light detected from the area of the tissue of the user and wherein a distance between the sensor and the area of the tissue remains relatively constant; a processing device configured to:\n process the PPG signal at the first wavelength detected over the area of the tissue of the user to identify a first motion artifact at a first time interval; and \n process the PPG signal at the first wavelength detected over the same area of the tissue of the user to identify a second motion artifact at a second time interval, wherein the first and second motion artifacts reflect changes in blood flow through vessels in the area of the tissue; \n correlate the first motion artifact in the PPG signal to a first predetermined PPG signal pattern, wherein the first PPG signal pattern reflects changes in blood flow through vessels in the area of the tissue at the first time interval; \n correlate the second motion artifact in the PPG signal to a second predetermined PPG signal pattern, wherein the second PPG signal pattern reflects changes in blood flow through vessels in the same area of the tissue at the second time interval; \n obtain first motion data for a first moving body part using the first predetermined PPG signal pattern; \n obtain second motion data for a second moving body part using the second predetermined PPG signal pattern, wherein the first moving body part and the second moving body part are different than a body part of the area of tissue of the user; and \n control operation of a device in response to the first motion data or the second motion data.
