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 the augmented reality display region extends in a field of view between a first boundary line and second boundary line of the field of view;
at least one augmented reality emitter which emits light to an eye of a user 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 region having a shape which corresponds to a shape of the augmented reality image, to provide the region with an opacity which is relatively high when the augmented reality image is at least a specified distance from the first boundary line and the second boundary line, and to provide a gradual transition in the opacity to a relatively low opacity as a head of the user moves sideward and the augmented reality image moves correspondingly toward the first boundary line, the gradual transition is based on a distance between the first boundary line and 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 an eye of a user 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; causing an opacity filter of the head-mounted display device to provide a first region of increased opacity, the first region of increased opacity is separated from the virtual object and corresponds to the size and shape of the virtual object; and causing the opacity filter to provide a second region of increased opacity which is behind the virtual object, from a perspective of the eye of the user, the second region of increased opacity is separated from the first region of increased opacity by a transmissive region of the opacity filter. - 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 between a first boundary line and a second boundary line, the opacity filter extends in a field of view, the field of view of the opacity filter comprises a central portion which is behind the augmented reality display region from a perspective of an eye of a user and a peripheral portion which is peripheral to the central portion from the perspective of the eye of the user; at least one augmented reality emitter which emits light to the eye of the user 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 make a detection of when the augmented reality image reaches the first boundary line as a head of the user moves sideward and the augmented reality image moves correspondingly toward the first boundary line, and in response to the detection, activate the opacity filter to provide a region of increased-opacity pixels in the peripheral portion of the field of view of the opacity filter, the region of increased-opacity pixels represents the augmented reality image. - View Dependent Claims (18, 19, 20)
