Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical see-through head-mounted display device, comprising: a see-through lens extending between a user's eye and a real-world scene when the display device is worn by the user, the see-through lens comprises an opacity filter and a display component, the opacity filter comprises a panel or film comprising a plurality of pixels, each pixel is individually controllable between minimum and maximum transmissivities to adjust an opacity of the pixel and to p…
