PURPOSE: A method for preventing erroneous input when inputting information through a touch screen, an operating device and a computer readable recording medium are provided to input data when contact of the touch screen ends. CONSTITUTION: A contact sensing unit senses the beginning and the end of contact about a touch screen. When the end of contact is sensed by the contact sensing unit, an input data obtaining unit(130) obtains input data corresponding to the end point of contact. A grammar checking unit(140) checks grammar about the obtained input data. When grammar of the input data is correct, the input data is displayed. A contact signal generator generates an electric signal corresponding to the contact end point.
