PURPOSE: A space touch apparatus of an infrared ray screen forming the infrared ray screen by using the infrared LED is provided to process a command of the user based on the location of the touch by recognizing the location of the touch. CONSTITUTION: An infrared LED(Light Emitting Diode) array(110) is arranged in a row and generates the infrared screen on the space. When the pulse signal is inputted from a pulse generator, an LED driver supplies the DC power supply to the infrared light emitting diode array. When the pulse signal is inputted, an infrared camera(120) takes a photograph of the infrared ray screen. A space touch recognition module recognizes the location touching the infrared ray screen on an image.
