The mobile terminal 100 includes a main body, a display unit 151, first and second grip sensors 142 and 143, a motion recognition sensor 144 (see FIG. 1), and a controller 180 (see FIG. 1).

Referring to FIG. 7, in a state where the first grip sensor 142 detects a touch input, an image may be displayed on the display unit 151 in the first display direction.

In this case, when the main body rotates, the motion recognition sensor 144 may detect a displacement according to the rotation of the main body, that is, the rotation direction and the rotation angle. For convenience of description, in the following drawings, whether the main body is rotated or not is shown through the relationship between the displacement and the gravity (G) direction according to the rotation of the main body.

The controller 180 may determine whether the detected rotation direction and rotation angle satisfy a rotation direction and rotation angle condition for switching the display direction of the image.

As a result of the determination by the controller 180, when it is determined that the rotation direction and the rotation angle condition for changing the display direction of the image are satisfied, and the second grip sensor 143 detects a touch input, the image is displayed with the first display direction. It may be displayed on the display unit 151 in another second display direction.

Referring to FIG. 8, in a state where the first grip sensor 142 detects a touch input, an image may be displayed on the display unit 151 in a first display direction.

In this case, when the main body rotates, the motion recognition sensor 144 may detect a displacement according to the rotation of the main body, that is, the rotation direction and the rotation angle. As a result of the determination by the controller 180, it is determined that the rotation direction and the rotation angle condition for changing the display direction of the image are satisfied, but when the second grip sensor 143 does not detect the touch input, the image is displayed in the second display direction. The display unit 151 may display the display unit 151 in the first display direction.

Referring to FIG. 9, in a state in which the first grip sensor 142 detects a touch input, an image may be displayed on the display unit 151 in the first display direction.
