Q1: Does the acceleration calculated from the speed match the observed acceleration? What differences do you notice? What could be their cause?
Q2: Is the number of steps logical?
From the provided data and calculations, it seems that there are some discrepancies between the observed acceleration and the calculated acceleration from speed.
-
The calculated acceleration from speed does not match the observed acceleration entirely. This mismatch can arise due to various factors like noise in accelerometer data and errors in integration.
-
The number of steps calculated from the z-component of acceleration might not be entirely logical. While acceleration in the z-direction can correspond to steps during walking (as the phone moves up and down with each step), it's unlikely that each peak or trough in the z-component corresponds to a single step. Factors such as irregular gait, variations in walking speed, and other movements could influence the z-component of acceleration, leading to an inaccurate step count.
