摘要： A multifocal test system is described herein. The system includes a plurality of displays located at different focal distances. Each display includes a plurality of pixels with pixel intensity values. The system includes an eye tracking system that determines eye tracking information about a position of an eye relative to the displays. A controller is configured to determine pixel intensity values based on decomposition of a scene across the plurality of displays, and the position of the eye.

摘要： Systems and methods for displaying an image across a plurality of displays are described herein. Pixel intensity values in the multifocal display are determined using correlation values and numerical iterations. An eye tracking system measures eye tracking information about a position of a user's eye, and the pixel intensity values are modified based on the eye tracking information. An image is displayed on the plurality of displays based on the determined pixel intensity values. The plurality of displays may be within an HMD, and address vergence accommodation conflict by simulating retinal defocus blur.

摘要： A first image and a second image are presented to a user of a head mounted display (HMD) so that the first image and the second image are perceived as a combined image. The first image is inset into the second image and the first image may be a higher resolution image than the second image. The first image and the second image may be presented at different focal lengths and various techniques are utilized to gracefully blend the first image and the second image.

摘要： 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.

摘要： A method includes providing frames of video data for being displayed by a head mounted display (HMD). Pixel data is encoded in a pixel of at least some of the video data frames, the encoded pixel data defining a focal state of an optics block of the HMD for displaying the respective frame of the video data to a user. The predetermined focal state is determined from a plurality of available focal states of the optics block, each focal state corresponding to a different focal plane of a virtual image generated based on the video data. The pixel used for encoding may be disposed outside a region of the frame that is displayable by the HMD.
