Abstract:
1. A mobile terminal for calculating a step length of a user, comprising: a pedometer to acquire a step count of the user; a Global Positioning System (GPS) receiver to calculate a position of the mobile terminal; and a processor configured to perform a procedure including: calculating a center position of a plurality of positions calculated by the GPS receiver; calculating a distance covered by the mobile terminal by calculating distances between adjacent pairs of a plurality of center positions calculated and adding up the distances; calculating the step length based on the step count acquired by the pedometer and the covered distance calculated; and correcting the calculated step length according to the step count by using a step length coefficient obtained from a step length correction table that defines a plurality of combinations of step count and step length coefficient such that the step length coefficient increases as the step count increases.
