Electronic device in accordance with various embodiments of the present invention, the touch screen may include a memory electrically coupled to the electrically connected to the processor and the processor to the display. The memory, when executed, the processor, display at least a reference character on the touch screen, and receives the touch gesture through the touch screen, and displays the trajectory of the received touch gesture on the touch-screen the touch the trajectory of the gesture recognition to at least one of the at least one input character corresponding to the reference characters, and distinguish between said at least one of the at least one of the input character, respectively and reference characters in at least one stroke according to a preset reference and, the at least one of the reference character with the at least one by the comparing the input character between the stroke corresponding to one another, determining a segment-specific error values, wherein the at least one of the reference characters and each of the segment-specific error values ​​with respect to the corresponding each other by summing and calculating a per-character error value, of said at least one The character-specific error values ​​related to each of the conference character may store instructions to be displayed in the touch screen. The other can be a variety of embodiments.
