User Localization Using a Wearable Sensor

GPS acquires location information by interrogating several satellites so acquisition is rather difficult indoors. Dead Reckoning is one solution; the path from the known departure point is calculated. This technique needs the length of stride, the velocity, and the estimated regression equation. However, this technique is limited to known individuals and normal walking action. This paper introduces a self-location estimation method for indoor environments that uses multiple regression equations to handle various walking styles.
