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 12):
A wearable device for detecting movement, comprising:\n a PPG sensor configured to obtain a PPG waveform from light detected from an area of skin adjacent to the wearable device of a user; a processing circuit in communication with the PPG sensor and configured to:\n determine a heart rate signal from the PPG waveform; \n determine a quality factor of the heart rate signal; \n when the quality factor exceeds a predetermined threshold, identify a first motion artifact at a first time interval and a second motion artifact at a second time interval artifact in the PPG waveform detected from the same area of skin adjacent to the wearable device of the user; \n compare the first and second motion artifacts to a plurality of predetermined PPG patterns in a database, wherein each of the plurality of predetermined PPG patterns is associated with one of a plurality of movements and one of a plurality of body parts; \n correlate the first motion artifact in the PPG waveform to a first predetermined PPG pattern in the database and determine a movement and an identification of a first body part of the user using the first predetermined PPG pattern; \n correlate the second motion artifact in the PPG waveform to a second predetermined PPG pattern in the database and determine a movement and an identification of a second body part of the user using the second predetermined PPG pattern; and \n wherein the first body part and the second body part are different than a body part including the skin adjacent to the wearable device.
