generating a locking-release preliminary signal on the locking; creating a locking-release icon based on a generated position of the locking-release preliminary signal; and releasing the locking by selecting the locking-release icon, and to a mobile terminal using the same. ## Claims ### Claim 1 A method for releasing a locking on a mobile terminal, the method comprising: locking the mobile terminal; generating a locking-release preliminary signal on the locking; generating a locking-release icon based on a generated position of the locking-release preliminary signal; and releasing the locking by selecting the locking-release icon. ### Claim 2 (depends on 1) The method of the claim 1, wherein the step of generating the locking-release preliminary signal comprises, determining, by a proximity sensor, whether a pointing device approaches within a predetermined distance; and generating a proximity signal if the pointing device approaches within the predetermined distance. ### Claim 3 (depends on 1) The method of the claim 1, wherein the step of generating the locking-release preliminary signal comprises being touched on a first area of a touch sensor, and the step of creating the locking-release icon based on the generated position of the locking-release preliminary signal comprises creating the locking-release icon on a second area which places near the first area. ### Claim 4 (depends on 1) The method of the claim 1, wherein the step of generating the locking-release preliminary signal comprises, being touched on a first area of a touch sensor, determining whether the size of the first area corresponds to that of a thumb of a human, and creating the locking-release preliminary signal when the size of the first area corresponds to that of the thumb of the human. ### Claim 5 (depends on 1) The method of the claim 1, wherein, the locking-release icon is a direction icon, and the step of releasing the locking by selecting the locking-release icon comprises detecting a dragging operation corresponding to a direction indicated by the direction icon. ### Claim 6 (depends on 1) The method of the claim 1, wherein, the step of generating a locking-release preliminary signal on the locking comprises limiting a preliminary signal area by user setting where the locking-release preliminary signal can be generated, and generating a locking-release preliminary signal on the locking by selecting the preliminary signal area. ### Claim 7 A mobile terminal comprising: a locking set-up unit configured to lock the mobile terminal; a sensing unit configured to generate a locking-release preliminary signal; a display unit configured to display a locking-release icon; and a controller configured to create the locking-release icon on the display unit based on a generated position of the locking-release preliminary signal, and to release the locking by selecting the locking-release icon. ### Claim 8 (depends on 7) The mobile terminal of the claim 7, wherein the sensing unit comprises a proximity sensor generating the locking-release preliminary signal by detecting a pointing device if the pointing device approaches within a predetermined distance. ### Claim 9 (depends on 7) The mobile terminal of the claim 7, wherein the sensing unit comprises a touch sensor having a first area where a pointing device is touched, and the controller creates to display the locking-release icon in a second area near the first area if the locking-release preliminary signal is generated by the touch of the first area. ### Claim 10 (depends on 7) The mobile terminal of the claim 7, wherein the sensing unit comprises a touch sensor having a first area where a pointing device is touched, and the controller creates to display the locking-release icon in a second area near the first area if the size of the first area corresponds to that of a thumb of a human. ### Claim 11 (depends on 7) The mobile terminal of the claim 7, wherein, the locking-release icon is a direction icon, and the controller controls to release the locking if a drag signal to the direction icon is generated. ### Claim 12 (depends on 7) The mobile terminal of the claim 7, wherein the controller controls to limit a preliminary area by user setting, where the locking-release preliminary signal is able to be generated. ### Claim 13 A mobile terminal comprising: a locking set-up unit configured to lock the mobile terminal; a sensing unit configured to generate a locking-release preliminary signal where a pointing device approaches a predetermined distance; a display unit configured to display a locking-release icon; and a controller configured to create the locking-release icon on the display unit based on a generated position of the locking-release preliminary signal, and to release the locking by selecting the locking-release icon. ### Claim 14 (depends on 13) The mobile terminal of the claim 13, wherein the sensing unit comprises a touch sensor having a first area where a pointing device is touched, and the controller creates to display the locking-release icon in a second area near the first area if the locking-release preliminary signal is generated by the touch of the first area. ### Claim 15 (depends on 13) The mobile terminal of the claim 13, wherein the sensing unit comprises a touch sensor having a first area where a pointing device is touched, and the controller creates to display the locking-release icon in a second area near the first area if the size of the first area corresponds to that of a thumb of a human. ### Claim 16 (depends on 13) The mobile terminal of the claim 13, wherein, the locking-release icon is a direction icon, and the controller controls to release the locking if a drag signal to the direction icon is generated. ### Claim 17 (depends on 13) The mobile terminal of the claim 13, wherein the controller controls to limit a preliminary area by user setting, where the locking-release preliminary signal can be generated.
