Abstract: The technology provides an augmented reality display system for displaying a virtual object to be in focus when viewed by a user. In one embodiment, the focal region of the user is tracked, and a virtual object within the user focal region is displayed to appear in the focal region. As the user changes focus between virtual objects, they appear to naturally move in and out of focus as real objects would in a physical environment. The change of focus for the virtual object images is caused by changing a focal region of light processing elements in an optical path of a microdisplay assembly of the augmented reality display system. In some embodiments, a range of focal regions are swept through at a sweep rate by adjusting the elements in the optical path of the microdisplay assembly.

Abstract: La tecnología provee un sistema de visualización de realidad aumentada para lograr que un objeto virtual aparezca enfocado cuando es observado por un usuario. En una materialización, se sigue el movimiento de la región focal del usuario, y se representa un objeto virtual dentro de la región focal del usuario para que aparezca en la región focal. A medida que el usuario cambia de focalización entre objetos virtuales, éstos parecen moverse de manera natural dentro y fuera de foco como lo harían objetos reates en un entorno físico. El cambio de focalización para las imágenes de objetos virtuales se produce cambiando una región focal de elementos procesadores de luz en un camino óptico de un ensamble de una micropantalla del sistema de visualización de realidad aumentada. En algunas realizaciones, se barre a través de un rango de regiones focales a un ritmo de barrida, mediante el ajuste de los elementos en el camino óptico del ensamble de la micropantalla.

Abstract: An augmented reality system provides improved focus of real and virtual objects. A see-through display device includes a variable focus lens a user looks through. A focal region adjustment unit automatically focuses the variable focus lens in a current user focal region. A microdisplay assembly attached to the see-through display device generates a virtual object for display in the user's current focal region by adjusting its focal region. The variable focus lens may also be adjusted to provide one or more zoom features. Visual enhancement of an object may also be provided to improve a user's perception of an object.

Abstract: An optical see-through head-mounted display device includes see-through lens which combines an augmented reality image with light from a real-world scene, while 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 LCD panel can be selectively controlled to be transmissive or opaque, based on size, shape and position of the augmented reality image. Eye tracking can be used to adjust 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 representation of the augmented reality image. In another aspect, opaque pixels are provided at a time when an augmented reality image is not present.
