Abstract: The present invention relates to an electronic pen and a control method therefor. The electronic pen is configured to: receive an infrared signal from a transmitting module located at a predetermined distance or more from the electronic pen; measure the time when the infrared signal is received; calculate a distance between the transmitting module and the electronic pen on the basis of the measured time; calculate two-dimensional (2D) coordinates of the electronic pen on the basis of the calculation result; output ink to a writing target object on the basis of the calculated 2D coordinates; when the distance between a sensor module and a first end of the pen point is within the predetermined distance, adjust the magnetic pole of a first magnetic body and the magnetic pole of a second magnetic body so that the magnetic pole of the first magnetic body and the magnetic pole of the second magnetic body become identical.

Abstract: Provided in a smart shoe module mounted to a smart shoe for analyzing the motion of a wearer and providing various functions, the smart shoe module comprising: an upper case which forms an upper outer experience of a pressure switch and elastically behaves by means of a pressure, which is applied in a first direction and has a particular value or larger, in order to accurately measure the motion of the wearer by measuring the pressure generated during walking of a wearer, as digital signals such as on-signal and an off-signal, and, moreover, minimize a manufacturing tolerance so as to prevent an error in distinguishing between an on-signal and an off-signal from being caused by the pressure generated during walking of the wearer; a lower case coupled to the lower end of the upper case and forming a lower end outer experience of the pressure switch; a substance amounted to the inside of the upper case and generating a signal in the first circuit unit through the elastic behavior; and a control unit for processing the signal generated in the first circuit unit.
