ABSTRACT:
An apparatus and method for determining a location of a movement distance measuring apparatus are provided. The apparatus and method determine whether the movement distance measuring apparatus is mounted at the waist of a pedestrian or is located in a pocket and uses a different step length estimation algorithm, e.g. a different step length estimation parameter coefficient, corresponding to the determined mounting position. The determination of whether the movement distance measuring apparatus is mounted to the waist of a pedestrian or is located in a pocket is performed on the basis of a gyro sensor.
