A key input device using a direction selection input unit, a method thereof, and a character input method using the device are provided to process inputted key values by a key input method in accordance with the character input method which is employed in itself, and then to provide the processed results to a user. A direction selection input unit(10) inputs a selection signal and a direction signal from a user. A storage unit(30) stores key values distinguished by time and frequency of the selection signal and the direction signal. An action detection decider(20) inquires about the key values distinguished by the time and frequency of the selection signal and the direction signal, from the storage unit(30).
