Adaptive rendering in artificial reality environments

1. A method comprising, by a computing device for displaying augmented reality:

determining a virtual content to be displayed with a scene of a real-world environment;

generating an image depicting the virtual content, the image having one or more first characteristics;

detecting, using one or more sensors, one or more second characteristics of the scene of the real-world environment;

comparing the one or more first characteristics of the image with the one or more second characteristics of the scene to determine a perceptibility of the virtual content;

determining, based on the determined perceptibility of the virtual content, that a visual enhancement is to be applied to the virtual content depicted in the image to enhance a contrast between the depicted virtual content and the scene;

generating a visually-enhanced image depicting the virtual content by applying the visual enhancement to the virtual content depicted in the image and reducing a brightness of the scene of the real-world environment; and

displaying the visually-enhanced image of the virtual content on a display of the computing device, wherein the scene of the real-world environment is visible through the display.

2. The method of claim 1 , wherein a contrast between a result of the visually-enhanced image overlaid onto the scene and an underlying region of the scene is perceptibly higher than a contrast between a result of the image overlaid onto the scene and the underlying region.

3. The method of claim 1 , wherein the one or more second characteristics of the scene of the real-world environment comprise one or more of color, luminance, clutter of one or more objects, depth of one or more objects, location of one or more objects, or location of a user.

4. The method of claim 1 , wherein generating the visually-enhanced image depicting the virtual content comprises generating the visually-enhanced image based at least in part on one or more user preferences.

5. The method of claim 1 , wherein the visually-enhanced image includes a line drawn around a perimeter of the virtual content depicted in the visually-enhanced image.

6. The method of claim 1 , further comprising:

identifying an initial area of the scene where the virtual content depicted in the image is to be displayed; and

identifying an alternative area of the scene having a greater contrast with the virtual content than the initial area of the scene;

wherein the virtual content depicted in the visually-enhanced image is displayed over the alternative area of the scene.

7. The method of claim 6 , wherein the alternative area of the scene is within a threshold distance of the initial area of the scene.

8. The method of claim 6 , further comprising:

determining that the alternative area of the scene is free of physical hazards for a user of the computing device.

9. The method of claim 6 , further comprising:

determining that the alternative area of the scene is free of people.

10. The method of claim 1 , wherein applying the visual enhancement comprises adjusting a gamma of the virtual content depicted in the image.

11. The method of claim 1 , wherein applying the visual enhancement comprises:

accessing a normal map of the virtual content; and

generating one or more virtual lighting effects for the virtual content based on the normal map.

12. The method of claim 11 , wherein the virtual content is a first person, and the normal map is generated based on depth data of the first person captured by a first device being utilized by the first person or a second device being utilized by a second person.

13. The method of claim 1 , wherein application of the visual enhancement comprises two or more of:

generating a tone mapping of the virtual content depicted in the image;

generating a line around a perimeter of the virtual content depicted in the image;

increasing a local contrast by applying a high-pass filter to the virtual content depicted in the image; or

increasing a saturation of the virtual content depicted in the image.

14. One or more computer-readable non-transitory storage media embodying software that is operable when executed by a computing device to:

determine a virtual content to be displayed with a scene of a real-world environment;

generate an image depicting the virtual content, the image having one or more first characteristics;

detect, using one or more sensors, one or more second characteristics of the scene of the real-world environment;

compare the one or more first characteristics of the image with the one or more second characteristics of the scene to determine a perceptibility of the virtual content;

determine, based on the determined perceptibility of the virtual content, that a visual enhancement is to be applied to the virtual content depicted in the image to enhance a contrast between the depicted virtual content and the scene;

generate a visually-enhanced image depicting the virtual content by applying the visual enhancement to the virtual content depicted in the image and reducing a brightness of the scene of the real-world environment; and

display the visually-enhanced image of the virtual content on a display of the computing device, wherein the scene of the real-world environment is visible through the display.

15. The media of claim 14 , wherein a contrast between a result of the visually-enhanced image overlaid onto the scene and an underlying region of the scene is perceptibly higher than a contrast between a result of the image overlaid onto the scene and the underlying region.

16. The media of claim 14 , wherein application of the visual enhancement comprises two or more of:

generate a tone mapping of the virtual content depicted in the image;

generate a line around a perimeter of the virtual content depicted in the image;

increase a local contrast by applying a high-pass filter to the virtual content depicted in the image; or

increase a saturation of the virtual content depicted in the image.

17. A system comprising:

one or more non-transitory computer-readable storage media including instructions; and

one or more processors coupled to the storage media, the one or more processors configured to execute the instructions to:

determine a virtual content to be displayed with a scene of a real-world environment;

generate an image depicting the virtual content, the image having one or more first characteristics;

detect, using one or more sensors, one or more second characteristics of the scene of the real-world environment;

compare the one or more first characteristics of the image with the one or more second characteristics of the scene to determine a perceptibility of the virtual content;

determine, based on the determined perceptibility of the virtual content, that a visual enhancement is to be applied to the virtual content depicted in the image to enhance a contrast between the depicted virtual content and the scene;

generate a visually-enhanced image depicting the virtual content by applying the visual enhancement to the virtual content depicted in the image and reducing a brightness of the scene of the real-world environment; and
