1. A wearable device that is wearable on a body of a user, the wearable device comprising:
- a display configured to display a screen;
a sensor configured to sense a motion of the user; and
a controller configured to control the display based on the sensed motion, wherein the controller is configured to determine whether the user is looking at the screen using sensing data at a motionless point corresponding to a first point where the motion of the user stops, wherein the sensing data at the motionless point for determining that the user is looking at the screen of the wearable device is determined based on an acceleration variation value from a second point prior to the motionless point to the motionless point by using at least one acceleration variation regarding at least one direction, and wherein the controller is further configured to obtain the sensing data at the motionless point by determining a first variation of acceleration between motion of the user at the second point prior to the motionless point and motion of the user at the motionless point in a forward-rear direction of the user and by determining a sum of a second variation of acceleration at the motionless point in a left-right direction of the user and a third variation of acceleration at the motionless point in an up-down direction of the user.

12. A method of controlling a wearable device that is wearable on a body of a user, the method comprising:
- sensing a motion of the user;
determining whether to display a screen on the wearable device based on the sensed motion; and
displaying the screen on the wearable device based on the determination, wherein the determining comprises determining whether the user is looking at the screen using sensing data at a motionless point corresponding to a first point where the motion of the user stops, wherein the sensing data at the motionless point for determining that the user is looking at the screen of the wearable device is determined based on an acceleration variation value from a second point prior to the motionless point to the motionless point by using at least one acceleration variation regarding at least one direction, and wherein the sensing data is obtained at the motionless point by determining a first variation of acceleration between motion of the user at the second point prior to the motionless point and motion of the user at the motionless point in a forward-rear direction of the user and by determining a sum of a second variation of acceleration at the motionless point in a left-right direction of the user and a third variation of acceleration at the motionless point in an up-down direction of the user. - View Dependent Claims (13, 14, 15, 16, 17, 18)
