Abstract

Provided are a method and a terminal for unlocking a locked mode of the terminal. The terminal may include a display to display a home screen in an unlocked mode and a lock screen in a locked mode, an appearance of the lock screen being the same as a home screen, a user interface to receive inputs to unlock the lock screen, and a controller configured to unlock the lock screen based on the received inputs. The input may be received when the lock screen is displayed on the display in the lock mode, the input having a prescribed pattern. When the prescribed pattern of the input corresponds to a previously stored unlocking pattern, the lock screen may be unlocked to display the home screen.

Claims

1. A method of unlocking a locked mode of a terminal, the method comprising:

displaying, on a touch screen for receiving inputs, a lock screen in a locked mode;

inputting, on the touch screen, a touch input on the lock screen having a prescribed pattern; and

displaying a home screen by unlocking the locked mode based on the touch input, wherein an appearance of the home screen is the same as an appearance of the lock screen.

2. The method of claim 1, further comprising:

setting, by a controller, a prescribed unlocking pattern for unlocking the terminal.

3. The method of claim 2, wherein the setting includes

inputting a starting point, an ending point, and a moving path on the touch screen, and

storing the starting point, the ending point, and the moving path.

4. The method of claim 3, wherein the setting includes

associating at least one icon on the lock screen to the starting point, the ending point or the moving path, the associated icon being positioned on the touch screen corresponding to the starting point, ending point or moving pattern of the unlocking pattern.

5. The method of claim 4, wherein the moving path of the prescribed unlocking pattern extends from the associated icon according to a prescribed pattern of movement to the ending point.

6. The method of claim 4, wherein the prescribed unlocking pattern traverses over the at least one icon associated with the starting point, ending point or the moving path.

7. The method of claim 3, wherein the setting includes

setting a lattice having a prescribed range from the starting point, and

extracting the moving path on the lattice based on the starting point.

8. The method of claim 3, further comprising:

comparing the input pattern to the set unlocking pattern, and

unlocking the terminal when the input pattern corresponds to the set unlocking pattern.

9. The method of claim 3, further comprising:

comparing the input pattern to the set unlocking pattern; and

displaying, on the touch screen, a notification indicating a result of the comparison when the input pattern does not correspond to the set unlocking pattern.

10. The method of claim 1, wherein the lock screen is changed when the home screen is changed such that the appearance of the lock screen and the home screen are the same, and

wherein at least one icon on the lock screen corresponds to at least one icon on the home screen.

11. The method of claim 1, wherein the inputting includes

inputting, at a user input interface, an input to unlock the terminal including at least one of a touch gesture of the user, a predetermined movement of the touch gesture, or an air flow caused by the user.

12. A non-transitory computer-readable medium comprising a program for instructing a computer to perform the method of claim 1.

13. A terminal comprising:

a display to display a home screen in an unlocked mode and a lock screen in a locked mode, an appearance of the lock screen being the same as a home screen;

a user interface to receive inputs to unlock the lock screen; and

a controller configured to unlock the lock screen based on the received inputs, wherein

the input is received when the lock screen is displayed on the display in the lock mode, the input having a prescribed pattern, and when the prescribed pattern of the input corresponds to a previously stored unlocking pattern, the lock screen is unlocked to display the home screen.

14. The device of claim 13, wherein the user interface includes a touch screen and the unlocking pattern is set using the touch screen, the unlocking pattern including a starting point, an ending point, and a moving path between the starting point and the ending point.

15. The device of claim 14, wherein the unlocking pattern includes at least one icon on the lock screen that is associated with the starting point, the ending point or the moving path.

16. The device of claim 15, wherein the unlocking pattern traverses over the at least one icon that is associated with the starting point, the ending point or the moving path.

17. The device of claim 15, wherein the moving path of the unlocking pattern extends from the icon associated with the starting point on the lock screen, along the moving path to the ending point.

18. The device of claim 14, wherein the controller sets a lattice having a preset range from the starting point, and extracts the moving path on the lattice based on the starting point.

19. The device of claim 13, wherein, when the appearance of the home screen is changed, the appearance of the lock screen is changed corresponding to the change to the home screen such that the lock screen and the home screen remain the same.

20. The device of claim 13, wherein the input at the user interface includes at least one of a touch gesture on a touch screen, a predetermined movement of a gesture input, or an air flow caused by a user.
