This Program will calculate the Gait Angle of knee flexion from the subject using sensor fusion inertial measurement unit by utilizing accelerometer and gyroscope from smartphone.
This program calculate raw data from the accelerometer and gyroscope sensor using knee flexion angular velocity formula.
for Accelerometer
for Gyroscope
then by using complementary filter alogrithm method we would get the Gait Angle Result which i represent in this project using plot table
complementary filter algorithm
For getting the raw dataset, i'm using Phypox App on smartphone https://phyphox.org/
By using this app, we can get a Linear Accelerometer and Gyroscope dataset using our smartphone as IMU.
which we tied to our leg around our thigh (look image for ilustration)
