Abstract
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.
