The present invention relates to an infinite marking execution system of a marking program for an electronic board to infinitely move a writing screen area while moving a writing screen up and down and left and right by creating at least two coordinates on the writing screen and an executing method thereof. The infinite marking execution system of an marking program for an electronic board comprises: the writing screen (210) displayed by the marking program operated by touch input signals such as a touch signal generated when a user touches the writing screen (210) with his/her fingers or an electric pen, a touch move signal generated when the object on the writing screen is moved by the user, and a touch-up signal generated when the object is not in contact with the writing screen (210) by the user; a touch input signal interpretation unit (220) for interpreting the touch input signals and for counting the number of the touch input signals generated on the writing screen (210); a writing screen movement mode on/off flag (221) for determining whether the touch move signal is a writing mode or writing screen movement mode; a touch input signal number recording unit (230) for recording the number of the touch input signals counted by the touch input signal interpretation unit (220); and a writing screen movement and operation unit (240) operated by the touch signal, touch move signal and touch-up signal. [Reference numerals] (220) Touch input signal interpretation unit; (221) Writing screen movement mode on/off flag; (230) Touch input signal number recording unit; (241) Touch writing operation executing unit; (242) Touch move writing operation executing unit; (243) Touch up writing operation executing unit; (244) Writing screen movement executing unit; (AA) Generation of a touch signal; (BB) Generation of a touch move signal; (CC) Generation of a touch up signal |
