In this work, we developed a smart wearable device for gait speed measurement with dual
wireless communication on the feet by using an inertia measurement unit (IMU) sensor. To
discover step counts and speed information, pitch and yaw angles were calculated
successfully from IMU signals using a Kalman filter and a moving average algorithm.
Walking step counts were calculated using the sensor; the results demonstrated almost zero
errors and averaged more than 90% accuracy in walking and running measurements. The …
