Abstract

A mobile terminal including a wireless communication unit configured to provide wireless communication; a touch screen; and a controller configured to receive a user signature that identifies a user and has a predetermined trace on the touch screen, and enter a user-only accessible folder based on the received user signature.

First claim

What is claimed is:

1. A mobile terminal comprising:
a wireless communication unit configured to provide wireless communication;
a touch screen; and
a controller configured to:
display a lock mode screen on the touch screen when the mobile terminal is in a locked state, wherein the lock mode screen does not react to a touch input other than a user's touch input for releasing the lock state,
activate and display a region for receiving a user signature on the touch screen in response to a predetermined touch input on the lock mode screen,
receive a user signature that identifies a user and has a predetermined trace on the activated region while the mobile terminal is in a locked state, and
release the locked state and allow entry to a user-only accessible folder based on the received user signature when the received user signature corresponds to a registered user signature.

2. The mobile terminal of claim 1 , wherein the controller is further configured to:
display a sub region on the touch screen in which a flicking input does not scroll information included in the sub region,
receive a flicking input in the sub region, and
activate the sub region for receiving the user signature based on the received flicking input.

3. The mobile terminal of claim 1 , wherein the predetermined input includes a stroke input applied to at least a portion of a body of the mobile terminal to generate a predetermined vibration in the mobile terminal.

4. The mobile terminal of claim 1 , wherein controller is further configured to:
display a background screen on the touch screen,
receive a pinch-out input applied to the touch screen as the predetermined touch input, and
display an area for receiving the user signature on the background screen.

5. The mobile terminal of claim 1 , wherein the predetermined input includes a touch input starting from a bezel and extending to the touch screen.

6. The mobile terminal of claim 1 , wherein the predetermined trace corresponding to the user signature is performed directly on the folder.

7. The mobile terminal of claim 1 , wherein the predetermined input includes a touch input of dragging an indicator area of the touch screen downwards by a multi-touch, and
wherein the controller is further configured to activate an area for receiving the user signature in the slid indicator area.

8. The mobile terminal of claim 1 , wherein the controller is further configured to:
turn power off to the touch screen, and
when a touch input is maintained at a spot where the trace according to the user signature is terminated for a predetermined period of time, turn on the power to the touch screen and enter the folder.

9. The mobile terminal of claim 1 , wherein the controller is further configured to:
display the folder to have first items when the user signature is traced with one finger, and
display the folder to have second items which is a restricted subset of the first items, when the user signature is traced using a stylus pen or a multi-touch input.

10. The mobile terminal of claim 1 , wherein the controller is further configured to:
receive a tag trace in addition to the user signature, and
display the folder with at least one filtered item filtered by the tag.

11. The mobile terminal of claim 1 , wherein the controller is further configured to:
receive a predetermined drag input with respect to an indicator area of the touch screen,
activate an area for receiving the user signature in the slid indicator area, and
display notification information related to items included in the folder on the slid indicator area.

12. The mobile terminal of claim 1 , wherein the controller is further configured to:
receive an input for associating at least one item displayed on the touch screen to the user signature, and
move the at least one item associated with the user signature to the folder.

13. The mobile terminal of claim 1 , wherein the controller is further configured to:
display an identifier in an indicator area of the touch screen indicating a state of entering the folder.

14. The mobile terminal of claim 1 , wherein the controller is further configured to:
pair the mobile terminal with a wearable device worn by the user,
receive at least one personal information included in the wearable device through the wireless communication unit, and
display the at least one personal information with contents included in the entered folder.

15. The mobile terminal of claim 1 , wherein the lock mode screen include a pattern guide for inputting of a pattern password, and
wherein the controller is configured to activate and display the region before displaying the pattern guide.

16. The mobile terminal of claim 15 , wherein the predetermined touch input is a flicking input rather than a touch input applied to a plurality of objects constituting the pattern guide.

17. The mobile terminal of claim 1 , wherein the predetermined touch input is a long touch input applied to an empty space of the lock mode screen.

18. A method of controlling a mobile terminal, the method comprising:
registering a user signature that identifies a user and has a predetermined trace;
displaying a lock mode screen on the screen when the mobile terminal is in a locked state, wherein the lock mode screen does not react to a touch input other than a user's touch input for releasing the lock state;
activating and displaying a region for receiving, via a controller of the mobile terminal, the user signature in response to a predetermined touch input on the lock mode screen;
receiving the user signature on the activated region while the mobile terminal is in the lock state; and
releasing the locked state and allowing entry to a user-only accessible folder when the received user signature is matched with the registered user signature.

19. The method of claim 18 , further comprising:
displaying a sub region on the touch screen in which a flicking input does not scroll information included in the sub region;
receiving a flicking input in the sub region; and
activating the sub region for receiving the user signature based on the received flicking input.
