A1
Abstract:
The present invention relates to a touch input processing system using ultrasonic waves, comprising: a touch panel made of reinforced glass; a plurality of sensors configured therein; and a protective cover installed on the edge of the touch panel, wherein the touch input processing system is configured to recognize an ultrasonic frequency, which is generated by an impact pressure occurring when a bullet from a gas gun or an electric gun collides with the touch panel, through a circuit, to calculate the sensing time difference between sensors that sense a signal that has the ultrasonic frequency, respectively, and to analyze the input position, which corresponds to the touch on the touch panel, in terms of X and Y coordinates.
