(a) Comparison of RMSE in estimation of PEP using features from single axes of gyroscope and accelerometer placed on the mid sternum, with RMSE in estimation using BCG features as a reference. (b) Comparison of RMSE in PEP estimation using combination of features from multiple axes of the gyroscope and accelerometer, with RMSE from BCG features as a reference. (c) Comparison of RMSE for PEP estimation using different regression techniques. (d) Comparing RMSE in estimated PEP from our method with RMSE calculated, using algorithms from recent literatures.
