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 communicator configured to transfer and receive data to and from a master device;
a sensor configured to sense a motion of the user; and
a controller configured to;
obtain sensing data at a motionless point corresponding to a first point when the motion of the user stops, by determining a first variation of acceleration between the motion of the user at a second point prior to the motionless point and the 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,determine whether the user is looking at the screen using the sensing data at the motionless point,control the display based on the sensed motion,wherein the controller is further configured to transmit a first message to the master device to request the master device to stop transfer of the data to the wearable device based on the sensor sensing that the user has not moved for a first duration.

16. A method of controlling a wearable device that is wearable on a body of a user, the method comprising:
-
communicating with a master device to transfer and receive data; sensing a motion of the user; obtaining sensing data at a motionless point by determining a first variation of acceleration between the motion of the user at a second point prior to the motionless point and the 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; determining whether the user is looking at a screen of the wearable device by using the sensing data at the motionless point corresponding to a first point where the motion of the user stops; and displaying the screen on the wearable device based on the determination, transmitting a first message to the master device to request the master device to stop transfer of the data to the wearable device based on sensing that the user has not moved for a first duration. - View Dependent Claims (17)

18. A non-transitory computer-readable storage medium having a program stored thereon for executing a method comprising:
-
communicating with a master device to transfer and receive data; sensing a motion of a user; obtaining sensing data at a motionless point by determining a first variation of acceleration between the motion of the user at a second point prior to the motionless point and the 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; determining whether the user is looking at a screen of a wearable device, by using the sensing data at the motionless point corresponding to a first point where the motion of the user stops; and displaying the screen on the wearable device based on the determination, transmitting a first message to the master device to request the master device to stop transfer of the data to the wearable device based on sensing that the user has not moved for a first duration.
