Abstract
Disclosed is a method of measuring the amount of exercise using a mobile communication terminal equipped with an acceleration sensor capable of measuring movement of a user. The method includes the steps of: a) measuring acceleration according to a change in the location of the mobile communication terminal by the acceleration sensor and detecting acceleration values of the terminal expressed in an orthogonal coordinate system where the acceleration sensor is set to a reference position; b) calculating gravitational acceleration direction values of the acceleration of the terminal from the acceleration values of the terminal detected in step a); c) detecting relative values of the acceleration values with respect to the gravitational acceleration direction values; and d) calculating the movement amount from the detected relative values.
