1. A character input method comprising:
- receiving a first interaction;
displaying a first character in response to the first interaction, the first character being at least one of Korean consonants;
receiving a second interaction successively after the first interaction;
identifying a second character that can be formed by combining the first character with a character according to the second interaction, the character being at least one of Korean vowels; and
displaying the second character by replacing the first character with the second character,wherein the first interaction comprises;
a touch interaction input to a particular character area on a touch keypad; and
the second interaction comprises at least one of;
a draw interaction created when the first interaction occurs and then dragged in a first direction without releasing a touch and configured to input a preset group of vowels —
, and |’
,a draw-and-backtrack-flick interaction created when the draw interaction is dragged a distance in a second direction, and is moved in a direction opposite to the second direction and then is moved back a shorter distance in the opposite direction and configured to input a preset group of vowels ‘
, and ’
, anda draw-and-backtrack-drag interaction created when the draw interaction is moved a distance in a third direction, and then is dragged back greater than a preset distance in a direction opposite to the third direction and configured to input a preset group of vowels ‘

Abstract
A character input system and method is provided that enables a user to input and edit block characters via a touch-based electronic device, with a limited number of input motions. The character input method includes receiving a first interaction, displaying a first character in response to the first interaction, receiving a second interaction successively after the first interaction, identifying a second character that is formed by combining the first character with a character according to the second interaction, and displaying the second character instead of the first character.
