The step count is an important information for developing services for smartphone users. Most existing step counting solutions restrict that: 1) the phone has to be fixed to the user and 2) the user cannot use the phone naturally while walking. We can see that these restrictions are inconvenient for users. In this paper, we propose a step calculation algorithm, which can relieve the above restrictions...
We propose a new center of gravity (COG) estimation method for application during walking which uses sensors attached only to the lower limbs. Our method estimates the upper body position by using lower limb position data in order to estimate COG. In this paper, we investigate the feasibility of our method by comparing our method to a commercial COG estimation method during both normal walking and...
