Opacity Filter For Display Device
First Claim
1. An optical see-through head-mounted display device, comprising:
- a see-through lens comprising an augmented reality display region and an opacity filter, the opacity filter comprising a plurality of pixels, each pixel is controllable to adjust an opacity of the pixel, and;
at least one augmented reality emitter which emits light to a user'"'"'s eye via the augmented reality display region, the light represents an augmented reality image having a boundary; and
at least one control circuit, the at least one control circuit is configured to cause the opacity filter to provide a gradual transition in opacity based on a distance from the boundary of the augmented reality image.

Abstract
An optical see-through head-mounted display device includes a see-through lens which combines an augmented reality image with light from a real-world scene, while an opacity filter is used to selectively block portions of the real-world scene so that the augmented reality image appears more distinctly. The opacity filter can be a see-through LCD panel, for instance, where each pixel of the LCD panel can be selectively controlled to be transmissive or opaque, based on a size, shape and position of the augmented reality image. Eye tracking can be used to adjust the position of the augmented reality image and the opaque pixels. Peripheral regions of the opacity filter, which are not behind the augmented reality image, can be activated to provide a peripheral cue or a representation of the augmented reality image. In another aspect, opaque pixels are provided at a time when an augmented reality image is not present.

11. A method for displaying an augmented reality image on a head-mounted display device, comprising:
-
emitting light to a user'"'"'s eye via an augmented reality display region of the head-mounted display device, the light represents an augmented reality image, the augmented reality image comprises a virtual object having a size and shape; and causing an opacity filter of the head-mounted display device to provide a first region of increased opacity which is separated from the virtual object and which corresponds to the size and shape of the virtual object. - View Dependent Claims (12, 13, 14, 15, 16)

17. An optical see-through head-mounted display device, comprising:
-
a see-through lens comprising an augmented reality display region and an opacity filter, the opacity filter comprising a plurality of pixels, each pixel is controllable to adjust an opacity of the pixel, the augmented reality display region extends in a central field of view of a user and the opacity filter extends in a peripheral field of view of the user, peripheral to the central field of view; at least one augmented reality emitter which emits light to the user'"'"'s eye via the augmented reality display region, the light represents an augmented reality image which has a shape and a movement; and at least one control circuit, the at least one control circuit is configured to detect when the augmented reality image reaches a boundary of the augmented reality display region, and in response, activate the opacity filter to provide a region of increased-opacity pixels which represents the augmented reality image in the peripheral field of view of the user. - View Dependent Claims (18, 19, 20)
