Mobile terminal and method of controlling the mobile terminal

1. A method of controlling a mobile terminal, the method comprising:

storing, in a memory of the mobile terminal, a plurality of fingerprint information on at least one of a finger-by-finger basis, a user-by-user basis, and a fingerprint pattern-by-pattern basis in association with different operations to be performed on the mobile terminal;

displaying an operation screen on a display module;

receiving a fingerprint-touch input through the display module, the display module configured to receive a touch input and simultaneously identify a fingerprint;

performing an operation on the mobile terminal corresponding to fingerprint information of the received fingerprint-touch input that matches with one of the stored plurality of fingerprint information; and

recognizing the received fingerprint-touch input as an ordinary touch input and performing a predefined operation corresponding to a point of detection of the received fingerprint-touch input if the fingerprint information of the received fingerprint-touch input is determined not to match one of the plurality of fingerprint information stored in the memory,

wherein the performing the operation comprises controlling the display of the operation screen in accordance with a control value corresponding to the fingerprint information that matches with the fingerprint information of the received fingerprint-touch input, and

wherein the controlling the display of the operation screen comprises scrolling the operation screen at a speed corresponding to the control value, changing a playback speed of the operation screen to a speed corresponding to the control value and moving the operation screen by a distance corresponding to the control value.

2. The method of claim 1 , further comprising:

searching the stored plurality of the fingerprint information for the fingerprint information of the received fingerprint-touch input; and

extracting the operation to be performed on the mobile terminal that corresponds with the searched fingerprint information of the received fingerprint-touch input.

3. The method of claim 1 , wherein the operation performed on the mobile terminal includes one of locking the mobile terminal, unlocking the mobile terminal, and temporarily unlocking the mobile terminal for a predetermined amount of time.

4. The method of claim 1 , wherein the operation performed on the mobile terminal includes one of locking all operating menus, locking only particular operating menus, unlocking only the particular operating menus and unlocking all operating menus.

5. The method of claim 1 , wherein the different operations to be performed on the mobile terminal stored in association with the plurality of fingerprint information include instructions for displaying different groups of menu icons.

6. The method of claim 5 , wherein the different groups of menu icons include menu icons representing operating system applications, menu icons representing downloaded applications, and menu icons representing user-preferred applications.

7. The method of claim 1 , wherein the operation performed on the mobile terminal includes playing a multimedia program on the mobile terminal at a predetermined playback speed corresponding to the fingerprint information of the received fingerprint-touch input that matches with one of the stored plurality of fingerprint information.

8. The method of claim 1 , further comprising:

outputting an indicating event indicating the operation is being performed on the mobile terminal.

9. The method of claim 1 , wherein the received fingerprint-touch input includes one of 1) a fingerprint-touch input generated by touching the display module with a finger and dragging the finger in a predetermined direction, 2) a fingerprint-touch input generated by touching the display module with a finger and dragging the finger in a predetermined pattern, 3) a fingerprint-touch input generated by touching a first position on the display module with a finger and dragging the finger from the first position to a second position on the display module, 4) a fingerprint-touch input generated by touching the display module with pressure, and 5) a fingerprint-touch input generated by touching the display module for more than a predefined amount of time.

10. A mobile terminal, comprising:

a memory configured to store a plurality of fingerprint information on at least one of a finger-by-finger basis, a user-by-user basis, and a fingerprint pattern-by-pattern basis in association with different operations to be performed on the mobile terminal;

a display module configured to display an operation screen and to receive a touch input and simultaneously identify a fingerprint; and

a controller configured to:

receive a fingerprint-touch input through the display module and perform an operation on the mobile terminal corresponding to fingerprint information of the received fingerprint-touch input that matches with one of the stored plurality of fingerprint information,

recognize the received fingerprint-touch input as an ordinary touch input and perform a predefined operation corresponding to a point of detection of the received fingerprint-touch input if the fingerprint information of the received fingerprint-touch input is determined not to match any of the plurality of fingerprint information stored in the memory, and

control the display of the operation screen in accordance with a control value corresponding to the fingerprint information that matches with the fingerprint information of the received fingerprint-touch input,

wherein the controller controlling the display of the operation screen comprises scrolling the operation screen at a speed corresponding to the control value, changing a playback speed of the operation screen to a speed corresponding to the control value and moving the operation screen by a distance corresponding to the control value.

11. The mobile terminal of claim 10 , wherein the controller is further configured to search the stored plurality of the fingerprint information for the fingerprint information of the received fingerprint-touch input, and to extract the operation to be performed on the mobile terminal that corresponds with the searched fingerprint information of the received fingerprint-touch input.

12. The mobile terminal of claim 10 , wherein the operation performed on the mobile terminal includes one of locking the mobile terminal, unlocking the mobile terminal, and temporarily unlocking the mobile terminal for a predetermined amount of time.

13. The mobile terminal of claim 10 , wherein the operation performed on the mobile terminal includes one of locking all operating menus, locking only particular operating menus, unlocking only the particular operating menus and unlocking all operating menus.

14. The mobile terminal of claim 10 , wherein the different operations to be performed on the mobile terminal stored in association with the plurality of fingerprint information include instructions for displaying different groups of menu icons.

15. The mobile terminal of claim 14 , wherein the different groups of menu icons include menu icons representing operating system applications, menu icons representing downloaded applications, and menu icons representing user-preferred applications.

16. The mobile terminal of claim 10 , wherein the operation performed on the mobile terminal includes playing a multimedia program on the mobile terminal at a predetermined playback speed corresponding to the fingerprint information of the received fingerprint-touch input that matches with one of the stored plurality of fingerprint information.

17. The mobile terminal of claim 10 , further comprising:

an output unit configured to output an indicating event indicating the operation is being performed on the mobile terminal.

18. The mobile terminal of claim 10 , wherein the received fingerprint-touch input includes one of 1) a fingerprint-touch input generated by touching the display module with a finger and dragging the finger in a predetermined direction, 2) a fingerprint-touch input generated by touching the display module with a finger and dragging the finger in a predetermined pattern, 3) a fingerprint-touch input generated by touching a first position on the display module with a finger and dragging the finger from the first position to a second position on the display module, 4) a fingerprint-touch input generated by touching the display module with pressure, and 5) a fingerprint-touch input generated by touching the display module for more than a predefined amount of time.
