The method includes identifying a stroke constituting a character based on an input sensed through a display of the electronic device, displaying the identified stroke through the display, identifying a language corresponding to the identified stroke, and identifying a variation value for a graphic effect of the displayed stroke based on a complexity of the identified language. ## Claims ### Claim 1 A method for applying a graphic effect in an electronic device, the method comprising: identifying a stroke constituting a character based on an input sensed through a display of the electronic device; displaying the identified stroke through the display; identifying a language corresponding to the identified stroke; and identifying a variation value for a graphic effect of the displayed stroke based on a complexity of the identified language. ### Claim 2 (depends on 1) The method of claim 1, wherein identifying the language corresponding to the identified stroke comprises: in response to a character corresponding to the identified stroke being identified, retrieving the language corresponding to the identified character based on a reference character stored in a memory of the electronic device. ### Claim 3 (depends on 1) The method of claim 1, further comprising: applying the graphic effect of the displayed stroke; in response to the identified language having been changed, retrieving a complexity corresponding to the changed language; refining the variation value based on the retrieved complexity; and applying the graphic effect of the displayed stroke according to the refined variation value. ### Claim 4 (depends on 1) The method of claim 1, wherein the variation value represents one of a time interval ranging from a time point at which the stroke is displayed to a time point at which the graphic effect is applied and a time interval ranging from a time point at which the graphic effect is applied to a time point at which the graphic effect is completely applied. ### Claim 5 (depends on 3) The method of claim 3, further comprising: in response to the complexity of the identified language having been increased, refining the variation value based on the increased complexity; and applying the graphic effect of the displayed stroke according to the refined variation value. ### Claim 6 (depends on 1) The method of claim 1, further comprising one of: applying the graphic effect of the displayed stroke; applying an effect in which the displayed stroke and a previously displayed stroke disappear sequentially; and applying an effect in which the displayed stroke and the previously displayed stroke disappear simultaneously. ### Claim 7 (depends on 6) The method of claim 6, wherein applying the effect in which the displayed stroke and a previously displayed stroke disappears comprises at least one of: applying an effect in which the displayed stroke disappears while a color of the displayed stroke is changed; and applying an effect in which the displayed stroke disappears while the displayed stroke is shifted to the left. ### Claim 8 An electronic device for applying a graphic effect comprising: a display; a memory; and a processor operatively coupled with the display and the memory and configured to: identify a stroke constituting a character, based on an input sensed through the display; display the identified stroke; identify a language corresponding to the identified stroke; and identify a variation value for a graphic effect of the displayed stroke based on a complexity of the identified language. ### Claim 9 (depends on 8) The electronic device of claim 8, wherein the processor is further configured to, in response to a character corresponding to the identified stroke being identified, retrieve a language corresponding to the identified character based on a reference character stored in the memory. ### Claim 10 (depends on 8) The electronic device of claim 8, wherein the processor is further configured to: in response to the identified language having been changed, retrieve a complexity corresponding to the changed language; refine the variation value based on the identified complexity; and apply a graphic effect of the displayed stroke based on the refined variation value. ### Claim 11 (depends on 8) The electronic device of claim 8, wherein the variation value represents a time interval ranging from one of a time point at which the stroke is displayed to a time point at which the graphic effect is applied and a time interval ranging from a time point at which the graphic effect is applied to a time point at which the graphic effect is completely applied. ### Claim 12 (depends on 10) The electronic device of claim 10, wherein the processor is further configured to: in response to the complexity of the identified language having been increased, refine the variation value based on the increased complexity; and apply the graphic effect of the displayed stroke according to the refined variation value. ### Claim 13 (depends on 8) The electronic device of claim 8, wherein the processor is configured to: apply an effect in which the displayed stroke and a previously displayed stroke disappear sequentially; or apply an effect in which the displayed stroke and the previously displayed stroke disappear simultaneously. ### Claim 14 (depends on 13) The electronic device of claim 13, wherein the processor is configured to: apply an effect in which the displayed stroke disappears while a color of the displayed stroke is changed; or apply an effect in which the displayed stroke disappears while the displayed stroke is shifted to the left. ### Claim 15 An electronic device for applying a graphic effect comprising: a display; a memory; and a processor operatively coupled with the display and the memory and configured to: identify a stroke constituting a character based on an input sensed through the display; display the identified stroke; identify a position where the displayed stroke is arranged on the display; and identify a variation value for a graphic effect of the displayed stroke based on the arranged position. ### Claim 16 (depends on 15) The electronic device of claim 15, wherein the variation value represents one of a time interval ranging from a time point at which the stroke is displayed to a time point at which the graphic effect is applied and a time interval ranging from a time point at which the graphic effect is applied to a time point at which the graphic effect is completely applied. ### Claim 17 (depends on 15) The electronic device of claim 15, wherein the processor is further configured to: apply an effect in which the displayed stroke and a previously displayed stroke disappear sequentially; or apply an effect in which the displayed stroke and the previously displayed stroke disappear simultaneously. ### Claim 18 (depends on 15) The electronic device of claim 15, wherein the processor is further configured to: apply an effect in which the displayed stroke disappears while a color of the displayed stroke is changed; or apply an effect in which the displayed stroke disappears while the displayed stroke is shifted to the left. ### Claim 19 (depends on 15) The electronic device of claim 15, wherein the processor is further configured to: identify a time for which the identified stroke is inputted; and refine the variation value based on the identified time. ### Claim 20 (depends on 19) The electronic device of claim 19, wherein the processor is further configured to: in response to the identified time being greater than or equal to an input time of a previously identified stroke, set the variation value to be higher; and in response to the identified time being shorter than the input time of the previously identified stroke set the variation value to be lower.
