How does IMU integrate data?

You can integrate the accelerations by simply summing the acceleration vectors multiplied by the timestep (period of the IMU) to get the velocity, then sum the velocities times the timestep to get the position.

Gandhi Yetish, Ronald McGregor, in Handbook of Behavioral Neuroscience, 2019. Accelerometry, also known as actigraphy in sleep research, is used to measure human movement. These devices record patterns of motion and nonmotion, which differ markedly between sleep and wake.
