Abstract
A method of estimating a moving direction of a user of an apparatus is provided. The method includes obtaining change information of acceleration according to motions of the user from an acceleration sensor mounted in an apparatus for estimating the moving direction of the user, calculating a reaction vector of force applied to a ground surface by feet of the user based on the change information of the acceleration, calculating an included angle between the moving direction of the user based on the reaction vector and an axis of a geomagnetic sensor that is included in the apparatus and detects change information of a magnetic field according to a position of the user, and determining the moving direction of the user based on a moving direction measurement value of the geomagnetic sensor mounted in the apparatus and the included angle.
