Abstract

The present specification relates to a mobile device, a head mounted display (HMD) paired with the mobile device and a method of controlling therefor, and more particularly, to a method of providing a notification for an occurrence of an event from at least one of the mobile device and the HMD based on a position of the mobile device for the HMD.

Claims

1. A mobile device, comprising:

a display unit configured to display content;

a sensor unit configured to detect an input signal and transmit the detected input signal to a processor;

a communication unit configured to transmit and receive a data;

a camera unit configured to capture an image in front direction; and

the processor configured to control the display unit, the sensor unit, the communication unit, and the camera unit,

wherein when the mobile device is paired with a head mounted display (HMD) and an event to which a notification to be provided occurs, the processor is further configured to;

receive a location information from the HMD, wherein the location information indicates whether the mobile device is positioned at a first view angle area of the HMD,

provide a detail notification for an occurrence of the event in the mobile device when the mobile device is positioned at the first view angle area of the HMD,

transmit a signal for providing the detail notification for the occurrence of the event to the HMD when the mobile device is positioned at 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.

2. The mobile device of claim 1, wherein the first view angle area comprises a third view angle area positioned at an inside of a predetermined angle within the first view angle area of the HMD and a fourth view angle area positioned at an outside of the predetermined angle within the first view angle area.

3. The mobile device of claim 2, wherein the processor is further configured to provide the detail notification for the occurrence of the event in the mobile device, when the mobile device is positioned at the third view angle area of the HMD, and

provide a simple notification for the occurrence of the event in the mobile device, when the mobile device is positioned at the fourth view angle area of the HMD.

4. The mobile device of claim 3, wherein the processor is further configured to transmit a signal for providing the simple notification for the occurrence of the event to the HMD, when the mobile device is positioned at the second view angle area of the HMD.

5. The mobile device of claim 1, wherein the location information comprises a distance between the mobile device and the HMD.

6. The mobile device of claim 5, wherein the processor is further configured to provide the detail notification for the occurrence of the event in the mobile device, when the distance between the mobile device and the HMD corresponds to a predetermined distance range, and

provide a simple notification for the occurrence of the event in the mobile device, when the distance between the mobile device and the HMD does not correspond to the predetermined distance range.

7. The mobile device of claim 6, wherein the processor is further configured to transmit a signal for providing the simple notification for the occurrence of the event to the HMD when the distance between the mobile device and the HMD does not correspond to the predetermined distance range.

8. The mobile device of claim 6, wherein the mobile device is positioned at the first view angle area of the HMD.

9. The mobile device of claim 1, wherein the processor is further configured to transmit a signal for providing a notification, which indicates an occurrence of the event, to the HMD, when a display screen of the mobile device is not facing a user.

10. The mobile device of claim 9, wherein the notification corresponds to the detail notification or a simple notification.

11. The mobile device of claim 9, wherein the mobile device is positioned at the first view angle of the HMD.

12. The mobile device of claim 1, wherein the HMD is in a wearing mode.

13. The mobile device of claim 1, wherein the processor is further configured to provide the detail notification for the occurrence of the event at the mobile device when the HMD is in a non-wearing mode.

14. The mobile device of the claim 1, wherein the processor is further configured to provide a vibration notification for the occurrence of the event in the mobile device when the mobile device is in contact with a user.

15. The mobile device of claim 14, wherein the mobile device is positioned at the second view angle area of the HMD.

16. The mobile device of claim 1, wherein the processor is further configured to identify an identification(ID) of the HMD,

transmit a signal for providing the detail notification for the event to the HMD when the ID of the HMD corresponds to a predetermined ID, and

provide the detail notification for the occurrence of the event in the mobile device when the ID of the HMD does not correspond to the predetermined ID.

17. The mobile device of claim 16, wherein the mobile device is positioned at the second view angle area of the HMD.

18. A head mounted display (HMD), comprising:

a display unit configured to display content;

a sensor unit configured to detect an input signal and transmit the detected input signal to a processor;

a communication unit configured to transmit and receive a data;

a camera unit configured to capture an image in front direction; and

the processor configured to control the display unit, the sensor 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 at a first view angle area of the HMD,

receive a detail notification for an occurrence of an event from the mobile device and provide the detail notification when the mobile device is positioned at 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.

19. A method of controlling a mobile device, comprising the steps of:

when a head mounted display (HMD) is paired with the mobile device and an event to which a notification is to be provided occurs,

receiving location information from the HMD, wherein the location information indicates whether the mobile device is positioned at a first view angle area of the HMD;

providing a detail notification for an occurrence of the event in the mobile device when the mobile device is positioned at 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 at 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.

20. A method of controlling a head mounted display (HMD), comprising the steps of:

pairing with a mobile device;

sensing a position of the mobile device with respect to the HMD;

transmitting location information, wherein the location information indicates whether the mobile device is positioned at a first view angle area of the HMD, to the mobile device; and

receiving a detail notification for an occurrence of an event from the mobile device and providing the detail notification when the mobile device is positioned at a second view angle area, wherein the second view angle area corresponds to an area outside of the first view angle area.
