Title: WEARABLE DEVICE AND REAL-TIME STEP LENGTH MEASUREMENT METHOD FOR DEVICE
Abstract:
A wearable device and a real-time step length measurement method for the device. A two-dimensional gait of a lower limb when a user walks and step length information of each step can be measured and outputted in real time, and the device and the method can be applied to detection of a gait asymmetry degree of the user. By using angular velocity and acceleration real-time data collected by four inertial sensor units, the lower-limb gesture and the step length of the user are computed and outputted by means of a geometric algorithm. The device is convenient to use, is not limited by sites, has low costs, can highly-accurately output the lower-limb gesture and the step length of the user in real time, and has high reliability and good promotion prospects.
