    • PURPOSE: A location detecting system using infrared rays and ultrasonic waves and a location detecting method are provided to calculates a distance between a receiving unit and an interface member by using a speed difference of infrared rays and ultrasonic waves, thereby rapidly and accurately detecting location information of the interface member. CONSTITUTION: A location detecting system comprises a display device, an interface member, a plurality of receiving units(140), and a control unit. The display unit displays images. Commands are input to the interface member and the interface member transmits infrared rays and ultrasonic waves to the display device. The receiving unit receives the infrared rays and ultrasonic waves. The control unit calculates location information of the interface member by using a difference of arrival time of the infrared rays and ultrasonic waves.
