Abstract
Load measuring partsandare provided with reaction sensorsandto measure loads at two positions, the tiptoe and the heel, on each sole of right and left feet of a wearing person. The reaction sensordetects a reaction force to a load on a front side of the right foot (right tiptoe), the reaction sensordetects a reaction force to a load on a rear side of the right foot (right heel), the reaction sensordetects a reaction force to a load on a front side of the left foot (left tiptoe), and the reaction sensordetects a reaction force to a load on a rear side of the left foot (left heel). The reaction sensorsandare arranged to detect, based on a change of a capacitance, the loads on the right and left feet during a walk action. A change of the load accompanied with a shift of the weight and a contact between the wearing person's foot and the ground can be detected.
