System and method for controlling mobile terminal using motion of the foot

A portable apparatus operating system using foot motion and a method thereof are provided to control a portable apparatus according to foot motion even when a user does not use the user's hand or the user does not carry the portable apparatus, thereby increasing the degree of freedom of each function's operation. A foot motion sensing module(100) comprises as follows. A sensor unit(120) senses a user's foot motion, and outputs sensor data by the user's foot motion. A controller(130) collects the sensor data by the user's foot motion, and controls so that the collected sensor data by the user's foot motion is transmitted to a portable apparatus. A short-range wireless communication unit(150) transmits the sensor data to the portable apparatus by using short-range wireless communication.
