摘要： A display assembly includes: a scene display screen; a privacy screen mounted over the scene display screen; a first mirror having a reflection side (“the first reflection side”) and a transmission side (“the first transmission side”). The first reflection side is mounted at an angle to the scene display screen for illumination; a background display screen faces the first transmission side for illumination thereof; and a housing arranged about the scene display screen, background display screen and first mirror for reducing ambient light within the housing including an opening for viewing of the reflection side of the first mirror therethrough. An image generation assembly is coupled to the scene display screen for producing a moving scene image thereon. The observer views the background display screen and the scene display screen simultaneously when viewing the reflection side of the first mirror and the privacy screen prevents viewing a secondary scene image.

摘要： A system projects a user-viewable, computer-generated or -fed image, wherein a head-mounted projector is used to project an image onto a retro-reflective surface, so only the viewer can see the image. The projector is connected to a computer that contains software to create virtual 2-D and or 3-D images for viewing by the user. Further, one projector each is mounted on either side of the user's head, and, by choosing for example a retro angle of less than about 10 degrees, each eye can only see the image of one of the projectors at a given distance up to 3 meters, in this example, from the retro-reflective screen. The retro angle used may be reduced with larger viewing distance desired. These projectors use lasers to avoid the need for focusing, and in some cases these projectors use instead of lasers highly collimated LED light sources to avoid the need for focusing.

摘要： Methods, devices and systems are disclosed for improved depth perception in stereoscopic night vision devices. Among these are embodiments for aligning information overlays in the stereo view with associated objects, and for generating stereo information from single lenses or intensifiers. In some illustrative embodiments, a camera and position sensor are provided for at least two viewers, e.g., a pilot and a copilot, such that when a scene overlaps between viewers, the system produces a stereoptic scene, in which the users can more accurately determine a difference in depth between two or more distant objects. An illustrative binocular night vision system uses a high-resolution depth map to present binocular images to a user. In some embodiments, supplementary content can be overlaid, with an appropriate binocular disparity that is based on the depth map.

摘要： The information processing device includes an image analysis unit (A4-i) and a content rendering unit. The image analysis unit (A4-i) generates spatial position/range information (D4) of a virtual space in which a spatial display performs 3D display based on a captured image of a marker displayed on the spatial display. The content rendering unit performs rendering processing of the spatial video presented in the virtual space, based on the spatial position/range information (D4) and a viewpoint position.

摘要： Provided are techniques for collaborative enhancement of volumetric video with a device having multiple cameras. A volumetric video is displayed as a holographic projection. In response to identifying one or more user actions of a user at the device with the holographic projection of the volumetric video, the volumetric video is updated and an updated holographic projection that indicates the one or more user actions of the user is displayed. Additional content is received for the updated volumetric video from a plurality of other devices, where the additional content comprises one or more user actions of other users at the plurality of other devices. The additional content is aggregated to generate an aggregated volumetric video that indicates the one or more user actions of the user and the one or more user actions of the other users. A further updated holographic projection based on the aggregated volumetric video is displayed.

摘要： A display system suitable for use inside an MRI system bore to display images to a patient undergoing an MRI procedure. The display system includes a curved display structure fitted inside the MRI bore, and having a width and length sufficient to present images to the patient inside the tunnel. First and second EMI shielding layers sandwich the curved display structure. A display electronics module is electrically connected to the curved display structure to provide video drive signals to the curved display structure. A housing for the display electronics module is configured to provide shielding to prevent EM signals from within the housing to affect MRI image processing.
