Systems, methods, and media for displaying real-time visualization of physical environment in artificial reality

1. A method comprising, by a computing system:

displaying a virtual-reality scene on a device worn by a user;

receiving a request from the user to display a visual representation of at least a portion of a physical environment surrounding the user;

accessing data associated with the physical environment captured by one or more cameras of the device;

generating, based on the data, depth measurements of one or more objects in the physical environment;

generating, based on the depth measurements, one or more three-dimensional (3D) models of the one or more objects in the physical environment;

rendering an output image based on a current viewpoint of an eye of the user and the one or more 3D models of the one or more objects in the physical environment;

generating, based on the output image, the visual representation requested by the user; and

displaying the visual representation with the virtual-reality scene to the user.

2. The method of claim 1 , wherein the visual representation is an outline of the one or more objects in the physical environment.

3. The method of claim 2 , wherein the displayed outline of the one or more objects is superimposed over the virtual-reality scene.

4. The method of claim 2 , wherein the displayed outline has a uniform color tint.

5. The method of claim 4 , wherein the virtual-reality scene is generated by an application and the uniform color tint is selected by the application.

6. The method of claim 1 , wherein generating the visual representation comprises applying a gradient filter to the output image.

7. The method of claim 1 , wherein the visual representation is generated by an operating system of the computing system.

8. The method of claim 1 , wherein the device worn by the user is a head-mounted device that blocks the user from seeing the physical environment directly.

9. The method of claim 1 , wherein:

the current viewpoint of the eye of the user corresponds to a first eye of the user; and

the visual representation and the virtual-reality scene are displayed on a first display of the device configured to be viewed by the first eye of the user.

10. The method of claim 9 , further comprising:

determining a second viewpoint of a second eye of the user;

rendering a second output image based on the second viewpoint of the user and the one or more 3D models of the objects;

generating a second visual representation of at least a portion of the physical environment surrounding the user; and

displaying the second visual representation with a second virtual-reality scene on a second display of the device configured to be viewed by the second eye of the user.

11. One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

display a virtual-reality scene on a device worn by a user;

receive a request from the user to display a visual representation of at least a portion of a physical environment surrounding the user;

access data associated with the physical environment captured by one or more cameras of the device;

generate, based on the data, depth measurements of one or more objects in the physical environment;

generate, based on the depth measurements, one or more three-dimensional (3D) models of the one or more objects in the physical environment;

render an output image based on a current viewpoint of an eye of the user and the one or more 3D models of the one or more objects in the physical environment;

generate, based on the output image, the visual representation requested by the user; and

display the visual representation with the virtual-reality scene to the user.

12. The media of claim 11 , wherein the visual representation is an outline of the one or more objects in the physical environment.

13. The media of claim 12 , wherein the displayed outline of the one or more objects is superimposed over the virtual-reality scene.

14. The media of claim 12 , wherein the displayed outline has a uniform color tint.

15. The media of claim 14 , wherein the virtual-reality scene is generated by an application and the uniform color tint is selected by the application.

16. A system comprising:

one or more processors; and

one or more computer-readable non-transitory storage media coupled to one or more of the processors and comprising instructions operable when executed by one or more of the processors to cause the system to:

display a virtual-reality scene on a device worn by a user;

receive a request from the user to display a visual representation of at least a portion of a physical environment surrounding the user;

access data associated with the physical environment captured by one or more cameras of the device;

generate, based on the data, depth measurements of one or more objects in the physical environment;

generate, based on the depth measurements, one or more three-dimensional (3D) models of the one or more objects in the physical environment;

render an output image based on a current viewpoint of an eye of the user and the one or more 3D models of the one or more objects in the physical environment;

generate, based on the output image, the visual representation requested by the user; and

display the visual representation with the virtual-reality scene to the user.

17. The system of claim 16 , wherein the visual representation is an outline of the one or more objects in the physical environment.

18. The system of claim 17 , wherein the displayed outline of the one or more objects is superimposed over the virtual-reality scene.

19. The system of claim 17 , wherein the displayed outline has a uniform color tint.

20. The system of claim 19 , wherein the virtual-reality scene is generated by an application and the uniform color tint is selected by the application.
