Abstract: A multiplanar head mounted display (HMD) includes two or more artificial display planes for each eye located at optical distances that can be dynamically adjusted based on a location within a scene presented by the HMD that the user views. For example, a scene is presented on two or more electronic display elements (e.g., screens) of the HMD. A focal length of an optics block that directs image light from the electronic display elements towards the eyes of a user is adjusted using a varifocal system (e.g., an element that mechanically changes a distance between a lens system in the optics block and the electronic display element, an element that changes shape of one or more lenses in the lens system in the optics block, etc.) based on a location or object within the scene where the user is looking.

Abstract: A head-mounted display (HMD) that includes a high resolution (HR) inset display and a peripheral display. The HR inset display is configured to display an inset region that includes a portion of an image at a first resolution that corresponds to a resolution of a fovea region of a human eye. The peripheral display displays a background region, the background region having a second resolution that is less than the first resolution, the second resolution corresponding to a resolution of a non-fovea region of the human eye. The HMD includes an optics block that combines the inset region and the background region to create composite content at retinal resolution, and direct the composite content to an exit pupil of the HMD corresponding to a location of an eye of a user of the HMD.

Abstract: A lens for a head mounted display is configured for directing and collimating image light from pixels of an electronic display to a pupil of a user's eye to lessen a pupil swim effect. A method of configuring a lens for directing and collimating image light from an electronic display to a pupil of a user's eye includes configuring the lens to lessen a difference between observed distortions of imagery displayed by the electronic display at different gaze angles of the user's eye.

Abstract: A head-mounted display (HMD) divides an image into a high resolution (HR) inset portion at a first resolution, a peripheral portion, and a transitional portion. The peripheral portion is downsampled to a second resolution that is less than the first resolution. The transitional portion is blended such that there is a smooth change in resolution that corresponds to a change in resolution between a fovea region and a non-fovea region of a retina. An inset region is generated using the HR inset portion and the blended transitional portion, and a background region is generated using the downsampled peripheral portion. The inset region is provided to a HR inset display, and the background region is provided to a peripheral display. An optics block combines the displayed inset region with the displayed background region to generate composite content.

Abstract: A near-eye-display (NED) includes an eye tracking system and a waveguide display. The eye tracking system tracks locations based on a location of the user's eyes. The waveguide display includes a light source, an output waveguide and a controller. The output waveguide includes a dynamic output grating that outputs an expanded image light to the tracked eyebox locations. The decoupling grating is a 2D array of spatially switchable liquid crystal (LC) pixels including an active subset of LC pixels emitting light to regions within the tracked eyebox locations. The decoupling grating dynamically out-couples the expanded image light to the tracked location based on switching instructions generated and provided by the controller.

Abstract: A head-mounted display (HMD) includes a multifocal block having one or more possible focal distances and includes a multifocal structure. The multifocal structure has a first focal distance and a second focal distance of the one or more possible focal distances. The multifocal structure includes one or more optical components positioned in series such that light from an electronic display is received and passes through each of the one or more optical components at least once before being output from the multifocal structure. The one or more optical components includes a switchable half waveplate (SHWP). The SHWP has a first state that causes the multifocal structure to output image light at the first focal distance, and a second state that causes the multifocal structure to output the image light at the first focal distance.
