Patent ID: 8744802

Claim:
A mobile terminal for calculating consumed calories of a user, comprising: a pedometer to acquire a step count of the user; a Global Positioning System (GPS) receiver to acquire a position of the mobile terminal by receiving a radio signal from an external device; and a processor configured to perform a procedure including: calculating, at a predetermined repetition period, a distance covered by the mobile terminal on the basis of a plurality of the positions acquired by the GPS receiver; calculating, at the predetermined repetition period, a step length based on the step count acquired by the pedometer and the covered distance that is calculated; 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; calculating an average step length by averaging a plurality of step lengths calculated and corrected throughout all the repetition periods, from a first repetition period up to a latest repetition period; and calculating consumed calories, using the average step length that is automatically calculated.
