Abstract

A method for managing wide view content in a virtual reality (VR) environment and an apparatus therefor are provided. The method includes receiving content covering 360 degree or a wider viewing angle than a viewing angle of a user of the first device and displaying, on the VR device, a first view displaying at least one portion of the content covering the viewing angle of the user on a first view area of a display of the VR device, and a second view covering 360 degree or the wider viewing angle of the content using convex projection on a second view area of the display.

Claims

1. A method of managing wide view content in a virtual reality (VR) device, the method comprising:

receiving content covering a wider viewing angle than a viewing angle of a user of the VR device; and

displaying, on the VR device,

a first view displaying at least one portion of the content covering the viewing angle of the user on a first view area of a display of the VR device, and

a second view covering the wider viewing angle of the content using convex projection on a second view area of the display.

2. The method of claim 1, wherein the content comprises content with coverage of 360 degree viewing angle.

3. The method of claim 1,

wherein the first view is provided from an in-focal view point within a VR sphere where the content is rendered on an inner surface of the VR sphere, and

wherein the second view is provided from an out-focal view point outside the VR sphere on the display of the VR device where the content is rendered on an outer surface of the VR sphere.

4. The method of claim 3, further comprising:

generating the first view based on angle information corresponding to the at least one portion of the content covering the viewing angle of the user on the first view area of the display of the VR device.

5. The method of claim 3, further comprising:

generating the second view based on metadata associated with the content.

6. The method of claim 1, further comprising:

connecting to a device via a network; and

transmitting the second view to the device for displaying the second view covering the wider viewing angle of the content using convex projection on a display of the device.

7. The method of claim 1, further comprising:

displaying a configuration setting menu on the first view area of the display of the VR device,

wherein the configuration setting menu comprises at least one of shape, location, a degree of transparency, color, type of the second view, or a device to be connected for displaying the second view.

8. The method of claim 1, further comprising:

interchanging the first view and the second view in terms of at least one of size, location, and shape of each of the first view and the second view on the display of the VR device.

9. The method of claim 1, further comprising:

rotating the second view in response to a user input at a predetermined interval while the first view is halted.

10. The method of claim 9, further comprising:

halting the rotation of the second view in response to a user input.

11. The method of claim 1, further comprising:

extracting angle information of the content from the content covering the wider viewing angle than the viewing angle of the user of the VR device,

wherein the displaying of the first view and the second view comprises displaying the first view and the second view based on the angle information.

12. The method of claim 11, further comprising:

rotating the first view and the second view according to a user input of the user and the angle information.

13. The method of claim 11, wherein the user input comprises at least one of head movement, an eye movement, a text input or a gesture input of the user.

14. The method of claim 11, wherein the changing of the first view and the second view comprises:

synchronizing the first view and the second view; and

changing, based on the synchronizing of the first view and the second view, the first view and the second view according to the user input of the user and the angle information.

15. The method of claim 1, wherein the first view is displayed using at least one of concave projection or plain projection.

16. The method of claim 1, wherein the second view provides an out-focal view of an in-focal view of the first view.

17. An apparatus for managing wide view content, the apparatus comprising:

a communication circuit for receiving content covering a wider viewing angle than a viewing angle of a user of the apparatus; and

a display for displaying;

a first view displaying at least one portion of the content covering the viewing angle of the user on a first view area, and

a second view covering the wider viewing angle of the content using convex projection on a second view area.

18. The apparatus of claim 17, further comprising:

at least one processor configured to generate the first view based on angle information corresponding to the at least one portion of the content covering the viewing angle of the user on the first view area of the display,

wherein the first view is generated based on an in-focal view point within a VR sphere where the content is rendered on an inner surface of the VR sphere, and

wherein the second view is generated based on an out-focal view point outside the VR sphere where the content is rendered on an outer surface of the VR sphere.

19. The apparatus of claim 17, wherein the communication circuit is further configured to:

connect to a device via a network, and

transmit the second view to the device for displaying the second view covering the wider viewing angle of the content using convex projection on a display of the device.

20. A non-transitory computer readable storage medium having a computer readable program stored therein, the computer readable program, when executed on a first device, configured to execute instructions to cause the first device to:

receive content covering a wider viewing angle than a viewing angle of a user of the first device; and

display, on the first device,

a first view displaying at least one portion of the content covering the viewing angle of the user on a first view area of a display of the first device, and

a second view covering the wider viewing angle of the content using convex projection on a second view area of the display.
