Real-world portals for virtual reality displays
A virtual reality scene is displayed via a display device. A real-world positioning of a peripheral control device is identified relative to the display device. Video of a real-world scene of a physical environment located behind a display region of the display device is captured via a camera. A real-world portal is selectively displayed via the display device that includes a portion of the real-world scene and simulates a view through the virtual reality scene at a position within the display region that tracks the real-world positioning of the peripheral control device.
1. A method, comprising:
displaying a virtual reality scene via a display device;
identifying a real-world positioning of a peripheral control device relative to the display device;
capturing video of a real-world scene of a physical environment located behind a display region of the display device via a camera; and
displaying a real-world portal via the display device, the real-world portal including a portion of the real-world scene and simulating a view through the virtual reality scene at a position within the display region,
wherein the position of the real-world portal within the display region tracks a section of a virtual field of view of the peripheral control device that is spaced away from and spatially locked to the real-world positioning of the peripheral control device.
2. The method of claim 1 , wherein the portion of the real-world scene is a limited field of view of the camera that is less than an entire field of view of the camera; and
wherein the limited field of view is defined by a virtual viewing window corresponding to the section that is spaced away from and spatially locked to the real-world positioning of the peripheral control device.
3. The method of claim 2 , wherein the section is a section of a cone that represents the virtual field of view of the peripheral control device.
4. The method of claim 2 , wherein the virtual viewing window is spaced away from the peripheral control device by a pre-defined distance in physical space.
5. The method of claim 2 , further comprising:
locking a real-world positioning of the virtual viewing window relative to the physical environment responsive to engagement of a view-lock mode in which the virtual viewing window is no longer spatially locked to the real-world positioning of the peripheral control device.
6. The method of claim 2 , further comprising:
locking the position at which the real-world portal is displayed within the display region responsive to engagement of a portal-lock mode in which the position within the display region no longer tracks the real-world positioning of the peripheral control device.
7. The method of claim 1 , wherein an application provides the virtual reality scene for display, and wherein the real-world portal is displayed as an overlay to the virtual reality scene provided by the application.
8. The method of claim 1 , wherein the display device is a head-mounted display device.
9. The method of claim 8 , wherein the head-mounted display device is a near-eye head-mounted display device that occludes a user's view of the physical environment.
10. The method of claim 8 , wherein the camera is an outward facing camera of the head-mounted display device that approximates a perspective of a user wearing the head-mounted display device.
11. The method of claim 1 , wherein the peripheral control device is a handheld controller.
12. The method of claim 1 , further comprising:
receiving a user input via a user interface of the peripheral control device; and
responsive to the user input, engaging or disengaging a real-world viewing mode, wherein:
while the real-world viewing mode is engaged, the real-world portal is displayed via the display device, and
while the real-world viewing mode is disengaged, the real-world portal is not displayed via the display device.
13. The method of claim 1 , wherein the portion of the real-world scene included in the real-world portal is displayed at an apparent real-world scale.
14. A virtual reality system, comprising:
a computing system configured to:
display a virtual reality scene via a display device;
identify a real-world positioning of a peripheral control device relative to the display device;
capture video of a real-world scene of a physical environment located behind a display region of the display device via a camera; and
display a real-world portal via the display device, the real-world portal including a portion of the real-world scene and simulating a view through the virtual reality scene at a position within the display region,
wherein the position of the real-world portal within the display region tracks a section of a virtual field of view of the peripheral control device that is spaced away from and spatially locked to the real-world positioning of the peripheral control device.
15. The virtual reality system of claim 14 , wherein the display device is a head mounted display device;
wherein the camera is an outward facing camera of the head-mounted display device; and
wherein the peripheral control device is a handheld controller.
16. The virtual reality system of claim 14 , wherein the computing system is further configured to:
receive a user input via a user interface of the peripheral control device; and
responsive to the user input, engage or disengage a real-world viewing mode, wherein:
while the real-world viewing mode is engaged, the real-world portal is displayed via the display device, and
while the real-world viewing mode is disengaged, the real-world portal is not displayed via the display device.
17. The virtual reality system of claim 14 , wherein the portion of the real-world scene is a limited field of view of the camera that is less than an entire field of view of the camera; and
wherein the limited field of view is defined by a virtual viewing window corresponding to the section that is spaced away from and spatially locked to the real-world positioning of the peripheral control device.
18. The virtual reality system of claim 17 , wherein the computing system is further configured to:
receive a user input via a user interface of the peripheral control device; and
responsive to the user input, lock a real-world positioning of the virtual viewing window relative to the physical environment such that the virtual viewing window is no longer spatially locked to the real-world positioning of the peripheral control device.
19. The virtual reality system of claim 14 , wherein the computing system is further configured to:
receive a user input via a user interface of the peripheral control device; and
responsive to the user input, lock the position at which the real-world portal is displayed within the display region such that the position within the display region no longer tracks the real-world positioning of the peripheral control device.
20. A storage machine holding instructions executable by a logic machine to:
display a virtual reality scene via a display device;
identify a real-world positioning of a peripheral control device relative to the display device;
capture video of a real-world scene of a physical environment located behind a display region of the display device via a camera; and
display a real-world portal via the display device, the real-world portal including a portion of the real-world scene and simulating a view through the virtual reality scene at a position within the display region,
wherein the position of the real-world portal within the display region tracks a section of a cone that represents a virtual field of view of the peripheral control device that is spaced away from and spatially locked to the real-world positioning of the peripheral control device.
