  • Patent number: 10539796
    Abstract: Described herein are systems and methods to provide privacy protection and brightness enhancement in an interactive environment. A system may include one or more of a headset, one or more light sources, one or more optical elements, one or more physical processor, and/or other components. A light source may be configured to generate linearly polarized light rays polarized on a first polarization plane along an axis of propagation. A reflective polarizer of an optical element may be configured to transmit light rays polarized on a second polarization plane transverse to the first polarization plane. Light rays polarized along the first polarization plane may be reflected off the reflective polarizer. An absorptive polarizer of an optical element may transmit light rays polarized on the second polarization plane so that light rays polarized along the second polarization plane may be transmitted through both the absorptive polarizer and the reflective polarizer.

  • Patent number: 10520735
    Abstract: Aspects of the disclosed apparatuses, methods and systems provide a wearable, augmented or virtual reality display system including two or more sets of backlight illumination arrangements. Each different set of backlight illumination is directed to a corresponding optical imaging system. The corresponding optical imaging system is designed to focus each set of illumination at a different distance. The selection of a particular optical focal distance is controlled by selecting the set of backlight illumination corresponding to the imaging system to provide the desired focal distance. As a result, selection of the backlight illumination determines at which distance an image is perceived by a user. When multiple backlight illumination sets are multiplexed with 2-D images, a single, 3-D image is perceived by the wearer of the display system.

  • Patent number: 10495879
    Abstract: Aspects of the disclosed apparatuses, methods, and systems provide enhanced display of images for personal wearable display devices. The display systems include various system components to implement one or more of: re-directing the maximal brightness of a display device towards the center of the eye-box of a user; selectively narrowing the viewing angle of light emitted by the display device; and by spatially optimizing the backlight of the display device based on the specification of the wearable optical system thereby optimizing and/or maximizing the amount of light entering the eye for a range of gaze rotation of a user of the wearable display system. In one example, the following description provides a display device including a light optimizing or directing layer. The light optimizing layer includes one or more films that optimize the amount of light directed to the eye box of a user of the wearable display system.

  • Patent number: 10473935
    Abstract: A system to provide views of virtual content in an interactive space, e.g., an augmented reality environment, may comprise one or more of a light source, directional control device, variable power lens, beam steering device, optical element, and/or one or more physical processors. A light source may generate collimated light rays in accordance with virtual content to be perceived within a three-dimensional light field. A directional control device may controllable adjust direction of travel of collimated light rays toward a beam steering device. A variable power lens may be positioned to receive collimated light rays between a light source and a directional control device. A beam steering device may be configured to direct collimated light rays to locations on an optical element. An optical element may be configured to reflect collimated light rays in a focal plane of a perceived three-dimensional light field.
