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 23):
A biosensor, comprising:\n a sensor configured to obtain a first PPG signal, wherein the first PPG signal includes a spectral response around a first wavelength of light detected from tissue of a first body part of a user; a processing device configured to:\n identify a fluctuation in the first PPG signal, wherein the fluctuation in the first PPG signal reflects neural activity or vasodilation of vessels in the tissue of the first body part of the user; \n correlate the fluctuation in the PPG signal to a first predetermined PPG signal pattern, wherein the first predetermined PPG signal pattern is associated with an intended movement of a second body part and wherein the intended movement is a mental movement with little to no actual movement of the second body part; \n determine the intended movement of the second body part using the first predetermined PPG signal pattern.
