Abstract

A mobile terminal and a method of controlling the operation of the mobile terminal are provided. The method includes placing the mobile terminal in lock mode; if a multi-touch signal including first and second touch signals is detected from a display module, releasing the mobile terminal from the lock mode, the first and second touch signals being touch signals detected from first and second areas, respectively, on the display module; and entering an operating mode which is set to enter upon the touching of the second area. Therefore, it is possible to unlock the mobile terminal and then readily enter a predefined operating mode in response to a multi-touch input detected from certain areas on the display module.

First claim

What is claimed is:

1. A mobile terminal comprising:
a touch screen;
a motion sensor; and
a controller configured to:
cause the touch screen to display a user interface for setting a predefined operating mode, the predefined operating mode set in response to an input received via the user interface, such that the mobile terminal enters the set predefined operating mode in response to a touch input received via the touch screen and a specific movement of the mobile terminal detected by the motion sensor while the mobile terminal is in a lock mode, the predefined operating mode comprising a camera mode;
cause the touch screen to display a lock screen when the mobile terminal is in the lock mode, wherein the mobile terminal remains in the lock mode when no movement of the mobile terminal is detected by the motion sensor while the touch input received via one or more arbitrary points of the touch screen displaying the lock screen is maintained;
unlock the mobile terminal that is in the lock mode and then enter the camera mode in response to detection of the specific movement of the mobile terminal by the motion sensor, the specific movement detected when the mobile terminal is rotated about an axis while the touch input received via one or more arbitrary points of the touch screen displaying the lock screen is maintained; and
cause the touch screen to display an operation screen associated with the camera mode instead of the lock screen when the mobile terminal is unlocked in response to the touch input and the specific movement that are received and detected concurrently.

2. The mobile terminal of claim 1 , wherein the motion sensor comprises at least an acceleration sensor or a gyro sensor.

3. The mobile terminal of claim 1 , wherein the receiving of the touch input and the detection of the specific movement of the mobile terminal occur sequentially such that the receiving of the touch input occurs prior to the detection of the specific movement, and the touch input is maintained on the touch screen while the specific movement is performed.

4. The mobile terminal of claim 1 , wherein:
the mobile terminal does not respond to any typical touch or key input while the mobile terminal is in the lock mode; and
the mobile terminal does not respond to the touch input received while the mobile terminal is in the lock mode unless the specific movement of the mobile terminal is detected sequentially or substantially at the same time such that the specific movement is detected while the touch input is maintained on the touch screen.

5. The mobile terminal of claim 1 , wherein the lock screen comprises at least a lock mode indicator, current time information, charge status information, or signal strength information.

6. The mobile terminal of claim 1 , wherein the touch input is received via a specific location of the touch screen such that the mobile terminal stays in the lock mode when a touch input is received at a location of the touch screen other than the specific location, when no touch input is received at the specific location, and when a specific movement of the mobile terminal is detected while the touch input received at the location of the touch screen other than the specific location is maintained.

7. The mobile terminal of claim 1 , wherein the predefined operating mode is pre-selected by a user via the user interface such that the predefined operating mode is changeable according to the user's selection of a function to be associated with the touch input and the specific movement of the mobile terminal.

8. A method of controlling a mobile terminal comprising a touch screen and a motion sensor, the method comprising:
displaying, on the touch screen, a user interface for setting a predefined operating mode, the predefined operating mode set in response to an input received via the user interface, such that the mobile terminal enters the set predefined operating mode in response to a touch input received via the touch screen and a specific movement of the mobile terminal detected by the motion sensor while the mobile terminal is in a lock mode, the predefined operating mode comprising a camera mode;
displaying a lock screen on the touch screen when the mobile terminal is in the lock mode, wherein the mobile terminal remains in the lock mode when no movement of the mobile terminal is detected by the motion sensor while the touch input received via one or more arbitrary points of the touch screen displaying the lock screen is maintained;
unlocking the mobile terminal that is in the lock mode and then entering the camera mode in response to detection of the specific movement of the mobile terminal by the motion sensor, the specific movement detected when the mobile terminal is rotated about an axis while the touch input received via one or more arbitrary points of the touch screen displaying the lock screen is maintained; and
displaying an operation screen associated with the camera mode, instead of the lock screen, on the touch screen when the mobile terminal is unlocked in response to the touch input and the specific movement that are received and detected concurrently.

9. The method of claim 8 , wherein the motion sensor comprises at least an acceleration sensor or a gyro sensor.

10. The method of claim 8 , wherein the touch input is received and then the specific movement of the mobile terminal is detected sequentially such that the receiving of the touch input occurs prior to the detection of the specific movement, and the touch input is maintained on the touch screen while the specific movement is performed.

11. The method of claim 8 , wherein:
the mobile terminal does not respond to any typical touch or key input while the mobile terminal is in the lock mode; and
the mobile terminal does not respond to the touch input received while the mobile terminal is in the lock mode unless the specific movement of the mobile terminal is detected sequentially or substantially at the same time such that the specific movement is detected while the touch input is maintained on the touch screen.

12. The method of claim 8 , wherein the lock screen comprises at least a lock mode indicator, current time information, charge status information, or signal strength information.

13. The method of claim 8 , wherein the touch input is received via a specific location of the touch screen such that the mobile terminal stays in the lock mode when a touch input is received at a location of the touch screen other than the specific location, when no touch input is received at the specific location, and when a specific movement of the mobile terminal is detected while the touch input received at the location of the touch screen other than the specific location is maintained.

14. The method of claim 8 , wherein the predefined operating mode is pre-selected by a user via the user interface such that the predefined operating mode is changeable according to the user's selection of a function to be associated with the touch input and the specific movement of the mobile terminal.
