US 12,118,680 B2 · Augmented reality lens selective tint adjustments

Abstract

In an example in accordance with the present disclosure, an augmented reality (AR) display device is described. The AR display device includes a frame to be worn on a head of a user and a lens disposed within the frame. A user is to view a physical scene through the lens. The lens includes multiple regions. Each region is individually addressable and has a tint value that is individually adjustable. The AR display device also includes an input to receive virtual content to be presented on the lens and an imaging system to present the virtual content on the lens. The AR display device also includes a controller which 1) identifies a first region of the lens on which the virtual content is to be presented and 2) selectively adjusts a tint of the first region while suppressing a tint adjustment to a second region of the transparent lens.

Dependent claims

An augmented reality (AR) display device, comprising:

a frame to be worn on a head of a user;
a lens disposed within the frame, wherein:
the user is to view a physical scene through the lens;
the lens comprises multiple regions;
each region is individually addressable;
and
a tint in each region is individually adjustable;
an input to receive virtual content to be presented on the lens;
an imaging system to present the virtual content on the lens;
and
a controller to:
identify a first region of the lens on which the virtual content is to be presented;
and
selectively adjust a tint of the first region by applying an electrical potential to produce an electric field across the first region while suppressing a tint adjustment to a second region of the lens,
wherein a degree of the tint to be selectively adjusted for the first region is based on pixel values of pixels that make up the virtual content to be presented, and the controller is to determine the pixel values of the virtual content from metadata associated with the virtual content.

A non-transitory machine-readable storage medium encoded with instructions executable by a processor, the machine-readable storage medium comprising instructions to, when executed by the processor, cause the processor to:

present virtual content on a lens of an augmented reality (AR) display device wherein:
a user is to view a physical scene through the lens;
the lens comprises multiple regions;
each region is individually addressable;
and
a tint in each region is individually adjustable;
generate a mapping between pixel addresses of the virtual content to regions of the lens;
determine a first region of the lens on which the virtual content is to be presented, including to:
identify a bounding region around the virtual content,
identify pixel addresses of the bounding region, and
identify the first region based on a mapping between the pixel addresses of the bounding region and the regions of the lens;
and
increase contrast between the physical scene viewable through the lens and the virtual content in the first region by:
applying an electrical current to the first region;
and
suppressing a current from passing to a second region where virtual content is not to be presented.
