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.

First claim

What is claimed is:

1. A method of unlocking a looked mode of a terminal, the method comprising:
setting, by a controller, an unlocking pattern for unlocking the terminal, including
receiving, on a touch screen, a first input to assign a starting point of the unlocking pattern of the touch screen pattern, and receiving, on the touch screen, a second input to assign an ending point of the unlocking pattern of the touch screen,
setting a lattice having a preset range from the starting point of the unlocking pattern, wherein the preset range of the lattice is smaller than the touch screen, and
after receiving the first input on the touch screen and receiving the second input on the touch screen, receiving a first touch-and-drag input to provide a moving path of the unlocking pattern inside the lattice that extends from the starting point to the ending point, wherein the moving path of the unlocking pattern has a prescribed shape that correspond to a continuous touch-and-drag input on the touch screen, and
storing the unlocking pattern including the starting point, the ending point, and the moving path corresponding to the first touch-and-drag input; and
unlocking, by the controller, the terminal, including:
displaying, on the touch screen, a home screen in a locked mode that includes a first icon displayed at the starting point on the home screen, wherein the first icon is assigned to the starting point of the unlocking pattern;
inputting, on the touch screen, a second touch-and-drag input on the home screen to provide a moving path, wherein the moving path of the second touch-and-drag input has a prescribed shape that starts from the first icon at the starting point displayed on the home screen, extends in a first direction to a predetermined point on the home screen, extends in a second direction from the predetermined point on the home screen, and then extends to an ending point, wherein the predetermined point is positioned at a location on the home screen not occupied by an icon or object displayed on the home screen;
in response to the second touch-and-drag input on the home screen, comparing the starting point of the second touch-and-drag input to the starting point of the stored unlocking pattern, comparing the ending point of the second touch-and-drag input to the ending point of the stored unlocking pattern, and comparing the moving path having the prescribed shape of the second touch-and-drag input to the moving path having the prescribed shape of the stored unlocking pattern;
displaying, on the touch screen, a notification indicating a result of the comparison when the starting point, the ending point, and the moving path having prescribed shape of the second touch-and-drag input does not correspond to the set unlocking pattern; and
displaying the home screen in an unlocked mode when the starting point, the ending point, and the moving path having the prescribed shape of the second touch-and-drag input corresponds to the starting point, the ending point, and the moving path having the prescribed shape of the moving path of the stored unlocking pattern,
wherein an appearance of the home screen is the same in the locked mode as in the unlocked mode.

2. The method of claim 1 , wherein the setting includes associating a second icon on the home screen to the ending point, the associated second icon being positioned on the touch screen corresponding to the ending point.

3. The method of claim 2 , wherein the moving path of the unlocking pattern extends from the first icon at the starting point to the second icon at the ending point.

4. The method of claim 2 , wherein the prescribed shape of the unlocking pattern traverses over the first icon associated with the starting point to the second icon associated with the ending point.

5. The method of claim 1 , wherein the home screen in the locked mode is changed when the home screen in the unlocked mode is changed such that the appearance of the home screen in the locked mode and the unlocked mode are the same, and
wherein the arrangement of icons on the home screen in the looked mode corresponds to the arrangement of the icons on the home screen in the unlocked mode.

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

7. A terminal comprising;
a display to display a home screen in an unlocked mode and in a locked mode, the home screen displaying a plurality of icons and an appearance of the home screen being the same in the locked mode as in the unlocked mode;
a user input device; and
a controller configured to set an unlocking pattern and to unlock the home screen when an input received at the user input device matches the unlocking pattern,
wherein the controller is configured to:
receive a first input to assign a starting point of the unlocking pattern on the display, and receive a second input to assign an ending point of the unlocking pattern on the display, wherein a first icon displayed on the home screen is associated with the starting point and a second icon displayed on the home screen is associated with the ending point,
set a lattice having a preset range from the starting point of the unlocking pattern, wherein the preset range of the lattice is smaller than the display,
after receiving the first input on the display and receiving the second input on the display, receive a first touch-and-drag input to provide a moving path of the unlocking pattern inside the lattice that extends from the starting point to the ending point, wherein the moving path of the unlocking pattern has a prescribed shape that corresponds to a continuous touch-and-drag input on the display between the first icon and the second icon, and
store the unlocking pattern including the starting point, the ending point, and the moving path corresponding to the first touch-and-drag input, and
wherein a second touch-and-drag input to unlock the terminal is received while the home screen is displayed on the display in the locked mode, the second touch-and-drag input has a moving path that starts from the first icon displayed on the home screen, extends in a first direction to a predetermined point on the home screen, extends in a second direction from the predetermined point, and then extends to an ending point, wherein the predetermined point is positioned at a location on the home screen not occupied by an icon or object displayed on the home screen, and
in response to the second touch-and-drag input, the controller is configured to:
compare a starting point of the second touch-and-drag input, the ending point of the second touch-and-drag input, and the moving path of the second touch-and-drag input having a prescribed shape to the starting point, the ending point, and the moving path of the stored unlocking pattern having the prescribed shape;
display, on the home screen, a notification indicating a result of the comparison when the starting point, the ending point, and the moving path having the prescribed shape of the second touch-and-drag input does not correspond to the set unlocking pattern; and
display the home screen in an unlocked mode when the starting point, the ending point, and the moving path having the prescribed shape of the second touch-and-drag input corresponds to the starting point, the ending point, and the moving path having the prescribed shape of the stored unlocking pattern.

8. The terminal of claim 7 , wherein the moving path of the unlocking pattern extends from the first icon associated with the starting point on the lock screen, along the prescribed shape of the moving path to the second icon associated with the ending point.

9. The terminal of claim 7 , wherein, when the appearance of
