Abstract
A device, computer program product and method of inputting a character in a touch screen device, in which a touch area is partitioned into a plurality of array positions, and one or more letters are assigned to each of the partitioned array positions. The method comprises the steps of: partitioning a touch area of the touch panel into a plurality of array positions and assigning one or more characters to each of the partitioned array positions; sensing an expansion event of selecting one among the array positions; dividing the touch area into a plurality of selection positions and assigning the characters assigned to the array position selected by the expansion event to the respective selection positions; sensing a selection event of selecting one among the selection positions; and recognizing the character assigned to the selection position selected by the selection event as an input character.
