A mobile terminal, comprising: a body including a front surface, and side surfaces connected to the front surface; a touch screen disposed at the front surface of the body, and configured to display a video play screen; a grip sensor configured to sense external forces having different intensities applied to both side surfaces of the body; and a controller configured to: execute a video-related function on the basis of a position where an external force having higher intensity is sensed through the grip sensor, and output a video play screen to the touch screen; characterized in that the controller is further configured to: when an external force having an intensity more than a preset intensity is applied while a video is played, stop playing the video, when the external force having an intensity more than the preset intensity is applied when the video play is stopped, re-play the video from the play stop time, when the external force having an intensity less than the preset intensity is applied to the side surfaces of the body, play the video, when the external force applied to the side surfaces of the body with an intensity less than the preset intensity is not sensed while the video is played, determine that the user is not viewing the video and stop the video play, when the external force having higher intensity is sensed on a left side surface of the body, execute a rewinding function of the video, and when the external force having higher intensity is sensed on a right side surface of the body, execute a fast-forward function of the video. a body including a front surface, and side surfaces connected to the front surface; a touch screen disposed at the front surface of the body, and configured to display a video play screen; a grip sensor configured to sense external forces having different intensities applied to both side surfaces of the body; and a controller configured to: execute a video-related function on the basis of a position where an external force having higher intensity is sensed through the grip sensor, and output a video play screen to the touch screen; characterized in that the controller is further configured to: when an external force having an intensity more than a preset intensity is applied while a video is played, stop playing the video, when the external force having an intensity more than the preset intensity is applied when the video play is stopped, re-play the video from the play stop time, when the external force having an intensity less than the preset intensity is applied to the side surfaces of the body, play the video, when the external force applied to the side surfaces of the body with an intensity less than the preset intensity is not sensed while the video is played, determine that the user is not viewing the video and stop the video play, when the external force having higher intensity is sensed on a left side surface of the body, execute a rewinding function of the video, and when the external force having higher intensity is sensed on a right side surface of the body, execute a fast-forward function of the video. execute a video-related function on the basis of a position where an external force having higher intensity is sensed through the grip sensor, and output a video play screen to the touch screen; when an external force having an intensity more than a preset intensity is applied while a video is played, stop playing the video, when the external force having an intensity more than the preset intensity is applied when the video play is stopped, re-play the video from the play stop time, when the external force having an intensity less than the preset intensity is applied to the side surfaces of the body, play the video, when the external force applied to the side surfaces of the body with an intensity less than the preset intensity is not sensed while the video is played, determine that the user is not viewing the video and stop the video play, when the external force having higher intensity is sensed on a left side surface of the body, execute a rewinding function of the video, and when the external force having higher intensity is sensed on a right side surface of the body, execute a fast-forward function of the video.
