The Characteristic Comparison of the Accelerometer and the Gyroscope Using the Pendulum Model of Body Sway

Abstract:

The accelerometer and gyroscope are used to identify the postural control disease as regards to the posturographic or sway analysis. For example, a gyroscope attached on the waist or head provides the several information such as sway area, sway velocity and others. However, prevalent methods did not describe the optimal position or reliable sensor for analysis. The purpose of this study is to observe and compare characteristics of accelerometers and gyroscopes according to attached positions because it can give the different results. We are assuming a pendulum model when the body sway, the 3-axis calibrated sensor accelerometer and gyroscope were attached on the different positions. From the experimental results, we have confirmed that the reliability of the accelerometers is depends on the position of the pendulum model contrast for the gyroscopes.
