• a display configured to electronically represent the received content as an image on a screen thereof;
• a sensor unit configured to detect a motion or gesture of a wearer of the wearable device;
• and
• a controller configured to control the communication unit and the display,
• wherein if the content displayed on the external device is changed from a first content to a second content different from the first content by a person other than the wearer of the wearable device, the controller controls the display to display the first content to be viewed by the wearer,
• wherein the first content is displayed only on the display of the wearable device, and
• wherein, the controller is configured to detect a specific motion or gesture of the wearer of the wearable device using the sensor unit, and if a content change signal is received after detecting the specific motion or gesture, determine the content displayed at the external device is changed from the first content to the second content by the person other than the wearer.

A method for controlling a wearable device including a display, the method comprising:

• changing a content currently displayed on an external device from a first content to a second content different from the first content;
• after the changing the content at the external device, displaying on the display of the wearable device a menu allowing a wearer of the wearable device to select whether the first content is displayed on the display;
• if the wearer selects to display the first content on the display using the menu, displaying the first content on the display to be viewed by the wearer;
• and
• determining whether the changing content is performed by the wearer of the wearable device,
• wherein during the displaying the first content on the display, the first content is displayed only on the display of the wearable device, and
• wherein the determining comprises:
• detecting a specific motion or gesture of the wearer of the wearable device;
• verifying whether a content change signal is received;
• and
• if the content change signal is received after detecting the specific motion or gesture, determining the changing the content is performed by the wearer of the wearable device.
