Validating response of wearable prototype device on estimating gait pattern

Abstract

This experimental study is to validate the accuracy of response of the prototype device in estimation of gait cycle pattern. The mercury filed prototype device has multiple channels through which mercury flow in. The direction of flow of mercury is channeled in four different directions. The change in directions and amount of mercury in a direction is directly propositional to force influence on the device. This mercury flows freely in between light source and light sensor. Movement of mercury interrupts the light intensity which is sensed by light sensor. Sensing the movement in different chamber and change in flow direction results in estimating the direction of force acting on it, which is induced by the object/ person wearing the device. The device is referred as Force reaction vector meter (FRVM)
