Patent attributes
Discussed are a smart watch and a control method thereof. The smart watch includes a rotation sensor unit configured to sense a rotation direction and a rotation speed of the smart watch; a display unit configured to display visual information; and a processor configured to control the rotation sensor unit and the display unit and detect a first snap motion and a second snap motion of the smart watch. The first snap motion is detected when the smart watch rotates on an axis of rotation of the smart watch in a first direction at a first threshold speed or more, and the second snap motion is detected when the smart watch rotates on the axis of rotation in the first direction at less than the first threshold speed and then rotates in a second direction at a second threshold speed or more within a predetermined time.
