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 movement of a body part or a control command for a user device. The PPG signals may thus be used to detect movement of the body part or determine a control command. A user device may be controlled in response to the determined control command.
