Abstract(in English) These days, because of its simplicity, noninvasiveness and unobtrusiveness, photoplethysmography (PPG) has been commonly used for wearable heart rate (HR) sensors. However, when applying a PPG-based HR sensor in exercise, human body motion introduces motion artifact (MA) and outliers in the output, which results in erroneous HR. In this paper, we investigate the part of our bodies where we can accurately and comfortably sense our HRs during exercise. We conduct experiments involving 13 human subjects, and we evaluate the performance of a PPG-based HR sensor. In the experiments, we select four human body parts such as forearm, wrist, waist and calf, and evaluate the HR at different fastening belt pressures, different exercise intensities and different data processing techniques. Our results show that the forearm is the best position and PPG/MA Cancellation (MACAN)/Spectrum Tracking (ST) is the best processing where the HR error can be the lowest with a tight belt pressure, achieving 7.53% in terms of RMSPE, that is, 10.62bpm in terms of RMSE.
