• a camera unit configured to capture an image in a front direction;
• and
• a processor configured to control the display unit, the communication unit, and the camera unit,
• wherein the processor is further configured to:
• pair with a mobile device,
• sense a position of the mobile device with respect to the HMD,
• transmit location information, wherein the location information indicates whether the mobile device is positioned within a first view angle area of the HMD,
• receive a detail notification for a notification of an occurrence of an event from the mobile device and provide the detail notification when the mobile device is positioned within a second view angle area of the HMD, wherein the second view angle area corresponds to an area outside of the first view angle area,
• wherein the notification includes a simple notification providing a simple information of the occurrence of the event or the detail notification providing a detail information of the occurrence of the event.

A method of controlling a mobile device, the method comprising:

• when a head mounted display (HMD) is paired with the mobile device and an event occurs for which a notification is to be provided, wherein the notification includes a simple notification providing a simple information of an occurrence of the event and a detail notification providing a detail information of the occurrence of the event,
• receiving location information from the HMD, wherein the location information indicates whether the mobile device is positioned within a first view angle area of the HMD;
• providing, at the mobile device, the detail notification for the occurrence of the event when the mobile device is positioned within the first view angle area of the HMD;
• and
• transmitting a signal for providing the detail notification for the occurrence of the event to the HMD when the mobile device is positioned within a second view angle area of the HMD, wherein the second view angle area corresponds to an area outside of the first view angle area.
