Abstract

An apparatus performs a method for locking automatic screen rotation in a portable terminal with a touch screen. The method for locking the screen rotation includes sensing a touch in a screen and, when a rotation of the portable terminal is sensed in a state where the touch is held, locking screen rotation.

Claims

1. A method for locking screen rotation in a portable terminal in which an automatic screen rotation service is activated, the method comprising:

sensing a touch in a screen of the portable terminal; and

when a rotation of the portable terminal is sensed in a state where the touch is maintained, locking or deactivating the automatic screen rotation service.

2. The method of claim 1, wherein the step of locking or deactivating the automatic screen rotation service comprises:

when the rotation of the portable terminal is sensed in the state where the touch is held, identifying a touch and hold time; and

when the touch is held during a reference time, locking or deactivating the automatic screen rotation service.

3. The method of claim 1, wherein the step of locking or deactivating the automatic screen rotation service comprises:

when the rotation of the portable terminal is sensed in the state where the touch is held, identifying the rotation direction of the portable terminal; and

when the rotation direction of the portable terminal is a reference direction, locking or deactivating the automatic screen rotation service.

4. The method of claim 1, further comprising:

after sensing the touch, identifying a touch and hold time; and

when the touch is held during a reference time, displaying a reference direction

wherein the reference direction indicates a criterion for determining whether the screen rotation locked.

5. The method of claim 1, further comprising executing a first application before sensing the touch.

6. The method of claim 5, further comprising, after the step of locking or deactivating the automatic screen rotation service, when the execution of the first application is ended, releasing the locked automatic screen rotation service or activating the automatic screen rotation service.

7. A method for rotating screen in a portable terminal in which an automatic screen rotation service is deactivated, the method comprising:

sensing a touch in a screen of the portable terminal; and

when a rotation of the portable terminal is sensed in a state where the touch is maintained, unlocking the deactivated automatic screen rotation service or activating the automatic screen rotation service.

8. The method of claim 7, wherein the step of unlocking the deactivated automatic screen rotation service or activating the automatic screen rotation service comprises:

when the rotation of the portable terminal is sensed in the state where the touch is held, identifying a touch and hold time; and

when the touch is held during a reference time, unlocking the deactivated automatic screen rotation service or activating the automatic screen rotation service.

9. The method of claim 7, wherein the step of unlocking the deactivated automatic screen rotation service or activating the automatic screen rotation service comprises:

when the rotation of the portable terminal is sensed in the state where the touch is held, identifying the rotation direction of the portable terminal; and

when the rotation direction of the portable terminal is a reference direction, unlocking the deactivated automatic screen rotation service or activating the automatic screen rotation service.

10. The method of claim 7, further comprising:

after sensing the touch, identifying a touch and hold time; and

when the touch is held during a reference time, displaying a reference direction,

wherein the reference direction indicates a criterion for determining whether the screen rotation.

11. A portable terminal in which an automatic screen rotation service is set, the terminal comprising:

a touch screen;

a sensing module configured to sense motion information of a portable terminal; and

a controller configured to, when a rotation of the portable terminal is sensed in a state where a touch on the touch screen is maintained, lock or deactivate the automatic screen rotation service.

12. The portable terminal of claim 11, wherein, when the rotation of the portable terminal is sensed in the state where the touch is held, the controller identifies a touch and hold time and, when the touch is held during a reference time, the controller locks or deactivates the automatic screen rotation service.

13. The portable terminal of claim 11, wherein, when the rotation of the portable terminal is sensed in the state where the touch is held, the controller identifies the rotation direction of the portable terminal and, when the rotation direction of the portable terminal is a reference direction, the controller locks or deactivates the automatic screen rotation service.

14. The portable terminal of claim 11, wherein, after sensing the touch on the touch screen, the controller identifies a touch and hold time and, when the touch is held during a reference time, the controller displays a reference direction on the touch screen,

wherein the reference direction indicates a criterion for determining whether the screen rotation locked.

15. The portable terminal of claim 11, wherein the controller is configured to execute a first application before sensing the touch on the touch screen.

16. The portable terminal of claim 15, wherein, after locking the screen rotation, when the execution of the first application is ended, the controller releases the locked automatic screen rotation service or activates the automatic screen rotation service.

17. A portable terminal in which an automatic screen rotation service is deactivated, the terminal comprising:

a touch screen;

a sensing module configured to sense motion information of a portable terminal; and

a controller configured to, when a rotation of the portable terminal is sensed in a state where a touch on the touch screen is maintained, unlock the deactivate automatic screen rotation service or activating the automatic screen rotation service.

18. The portable terminal of claim 17, wherein, when the rotation of the portable terminal is sensed in the state where the touch is held, the controller identifies a touch and hold time and, when the touch is held during a reference time, the controller unlocks the deactivates automatic screen rotation service or activating the automatic screen rotation service.

19. The portable terminal of claim 17, wherein, when the rotation of the portable terminal is sensed in the state where the touch is held, the controller identifies the rotation direction of the portable terminal and, when the rotation direction of the portable terminal is a reference direction, the controller unlocks the deactivates automatic screen rotation service or activating the automatic screen rotation service.

20. The portable terminal of claim 17, wherein, after sensing the touch on the touch screen, the controller identifies a touch and hold time and, when the touch is held during a reference time, the controller displays a reference direction on the touch screen,

wherein the reference direction indicates a criterion for determining whether the screen rotation.
