Abstract
Methods and systems for estimating a blood pressure of a user of a computing device are disclosed herein. The method can include obtaining at least one calibration trace, the at least one calibration trace being constructed to yield a fit between one or more selected reference traces and a corresponding parameter reference value for each of the one or more selected reference traces and obtaining a photoplethysmography (PPG) trace associated with a heartbeat cycle. The method can also include determining a convolution of the PPG trace with the at least one calibration trace, determining a blood pressure estimate for the user based on the convolution of the PPG trace with the at least one calibration trace, and providing data representing the blood pressure estimate.
