Abstract: Peripheral-vision expanded images are streamed to a video streaming client. The peripheral-vision expanded images are generated from source images in reference to view directions of the viewer at respective time points. View direction data is collected and received in real time while the viewer is viewing display images derived from the peripheral-vision expanded images. A second peripheral-vision expanded image is generated from a second source image in reference to a second view direction of the viewer at a second time point. The second peripheral-vision expanded image has a focal-vision image portion covering the second view direction of the viewer and a peripheral-vision image portion outside the focal-vision image portion. The second peripheral-vision expanded image is transmitted to the video streaming client.

The non-uniform illumination pattern comprises different values of the one or more illumination properties in first and second spatial regions of the display panel. An illumination compensation pattern is generated based at least in part on the non-uniform illumination pattern. The illumination compensation pattern is configured to homogenize values of the illumination properties in a plurality of spatial regions of the display panel that include the first and second spatial regions, and implemented in the display device.

Abstract: A wearable device includes circuitry on substrate. The substrate is coupled to an optical element in an optical stack. A refractive index of the substrate perceptually matches a refractive index of the optical component. The circuitry is imperceptible to the viewer wearing the device, despite that the circuitry has a view of (or, as an example, an unobstructed line of sight to) the viewer's eye. The circuitry can include a camera or an emitter, or both. The camera captures one or more reflections of the emitter from the viewer's eye. In a specific embodiment, the substrate includes a waveguide, Fresnel lenses, or lens to bend light rays around from the circuitry to achieve the imperceptibility. In alternative embodiment, the circuitry can be a piezoelectric device, liquid crystal controller, or any electronic circuitry relevant for a wearable device.

Abstract: While a viewer is viewing a first stereoscopic image comprising a first left image and a first right image, a left vergence angle of a left eye of a viewer and a right vergence angle of a right eye of the viewer are determined. A virtual object depth is determined based at least in part on (i) the left vergence angle of the left eye of the viewer and (ii) the right vergence angle of the right eye of the viewer. A second stereoscopic image comprising a second left image and a second right image for the viewer is rendered on one or more image displays. The second stereoscopic image is subsequent to the first stereoscopic image. The second stereoscopic image is projected from the one or more image displays to a virtual object plane at the virtual object depth.

Abstract: Techniques for driving a dual modulation display include generating backlight drive signals to drive individually-controllable illumination sources. The illumination sources emit first light onto a light conversion layer. The light conversion layer converts the first light into second light. The light conversion layer can include quantum dots or phosphor materials. Modulation drive signals are generated to determine transmission of the second light through individual subpixels of the display. These modulation drive signals can be adjusted based on one or more light field simulations. The light field simulations can include: (i) a color shift for a pixel based on a point spread function of the illumination sources; (ii) binning difference of individual illumination sources; (iii) temperature dependence of display components on performance; or (iv) combinations thereof.
