Mobile terminal and control method thereof

1. A mobile terminal comprising:

a wireless communication unit configured to provide wireless communication;

a touch screen; and

a controller configured to:

display a video screen on the touch screen,

perform a first operation if a second gesture is not sequentially inputted after an input of a first gesture, and

perform a second operation if the second gesture is sequentially inputted after the input of the first gesture,

wherein the first gesture is a touch and drag on the touch screen with a first finger,

wherein the second gesture is a gesture of pressing the touch screen with the first finger or a second finger while the first finger remains touched to the touch screen after the first gesture,

wherein the first operation is an operation of changing a video on the video screen,

wherein the second operation is an operation of controlling a playback speed of the video on the video screen based on a strength of the second gesture, and

wherein the controller is further configured to:

increase the playback speed of the video when the strength of the second gesture increases, and

reduce the playback speed of the video when the strength of the second gesture decreases.

2. The mobile terminal according to claim 1 , wherein the touch and drag comprises dragging the touch screen from a left side to a right side, and

wherein the second finger is a middle finger and the first finger is an index finger.

3. The mobile terminal according to claim 1 , wherein the touch and drag comprises dragging the touch screen from a right side to a left side, and

wherein the second finger is an index finger and the first finger is a middle finger.

4. The mobile terminal according to claim 1 , wherein the controller is further configured to display an identifier for informing an end time of the video on the touch screen and end the playback of the video in response to the controlling the playback speed of the video reaching the end time of the video.

5. The mobile terminal according to claim 1 , wherein the controller is further configured to display a playback speed icon on the touch screen for controlling the playback speed of the video at a location of the second gesture.

6. The mobile terminal according to claim 1 , wherein the first gesture with the first finger and the second gesture with the second finger comprises a multi-touching operation.

7. The mobile terminal according to claim 1 , wherein the touch screen includes an electrostatic touch sensor configured to determine the strength of the second gesture based on a voltage recognized by the touch sensor.

8. The mobile terminal according to claim 1 , further comprising:

at least one pressure sensor configured to determine the strength of the second gesture based on a pressure recognized by the at least one pressure sensor.

9. The mobile terminal according to claim 1 , further comprising:

a pressure-touch sensor including an integrated pressure and touch sensor configured to determine the strength of the second gesture.

10. The mobile terminal according to claim 1 , wherein the controller is further configured to display a next video in a video list for changing the video on the video screen.

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

displaying, via a controller of the mobile terminal, a video screen on a touch screen of the mobile terminal;

performing, via the controller, a first operation if a second gesture is not sequentially inputted after an input of a first gesture; and

performing, via the controller, a second operation if the second gesture is sequentially inputted after the input of the first gesture,

wherein the first gesture is a touch and drag on the touch screen with a first finger,

wherein the second gesture is a gesture of pressing the touch screen with the first finger or a second finger while the first finger remains touched to the touch screen after the first gesture,

wherein the first operation is an operation of changing a video on the video screen,

wherein the second operation is an operation of controlling a playback speed of the video on the video screen based on a strength of the second gesture, and

wherein the method further comprises:

increasing the playback speed of the video when the strength of the second gesture increases; and

reducing the playback speed of the video when the strength of the second gesture decreases.

12. The method according to claim 11 , wherein the touch and drag comprises dragging the touch screen from a left side to a right side, and

wherein the second finger is a middle finger and the first finger is an index finger.

13. The method according to claim 11 , wherein the touch and drag comprises dragging the touch screen from a right side to a left side, and

wherein the second finger is an index finger and the first finger is a middle finger.

14. The method according to claim 11 , further comprising:

displaying an identifier for informing an end time of the video on the touch screen and ending playback of the video in response to the controlling the playback speed of the video reaching an end time of the video.

15. The method according to claim 11 , further comprising:

displaying a playback speed icon on the touch screen for controlling the playback speed of the video at a location of the second gesture.

16. The method according to claim 11 , wherein the first gesture with the first finger and the second gesture with the second finger comprises a multi-touching operation.

17. The method according to claim 11 , further comprising:

determining the strength of the second gesture based on a voltage recognized by an electrostatic touch sensor of the touch sensor.

18. The method according to claim 11 , further comprising:

determining the strength of the second gesture based on a pressure recognized by a pressure sensor.

19. The method according to claim 11 , further comprising:

determining the strength of the second gesture via a pressure-touch sensor including an integrated pressure and touch sensor.

20. The mobile terminal according to claim 11 , further comprising:

displaying a next video in a video list for changing the video on the video screen.
