Because the measurement of foot biomechanics information mostly relies on expensive experimental instruments (VICON motion capture equipment and pressure plate) with high establishment costs and limitation of measurement being conducted in laboratory environment so as to lack universality. In the past, user must visit the experiment locations back-and-forth for several times and replied on experts to help calibration and measurement which is time-consuming and extremely inconvenient. This technology proposed portable solution of wearable devices integrating with mobile phone for user to monitor foot gaits at all times and shall significantly mitigate measuring manpower and time costs.
