Abstract:
1. A smart watch comprising: 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; a position sensor unit configured to sense a position of the smart watch; and a processor configured to control the rotation sensor unit and the display unit, wherein the processor is further configured to: detect whether the smart watch is in a first position or a second position using the position sensor unit, the first position being when the display unit is worn on a back side of a hand of a user, the second position being when the display unit is worn on a palm side of the hand of the user, wherein when the processor detects the first position, a first direction is an outward direction and a second direction is an inward direction, and wherein when the processor detects the second position, the first direction is an inward direction and the second direction is an outward direction, detect a first snap motion and a second snap motion of the smart watch in the detected first or second position, wherein the first snap motion is detected when the smart watch rotates on an axis of rotation of the smart watch in the first direction set according to the detected position of the smart watch, at a speed higher than a threshold speed, and wherein the second snap motion is detected, when the smart watch rotates on the axis of rotation in the first direction at a speed lower than the threshold speed and then rotates on the axis of rotation in the second direction set according to the detected position of the smart watch, at a speed higher than the threshold speed within a predetermined time, the second direction being an opposite direction of the first direction, and execute a first command corresponding to the first direction when the first snap motion is detected, and execute a second command corresponding to the second direction when the second snap motion is detected.
